 sales and transportation customers within its service area of approximately
 275 square miles, located in northeastern Illinois.

The Power Generation segment is engaged in the development, construction,
 operation, and ownership of gas-fired electric generation facilities for sales
 to electric utilities and marketers.  The Company and Dominion Resources Inc. are
 equal investors in Elwood Energy, which owns and operates a 600-megawatt peaking
 facility near Chicago, Illinois.

The Midstream Services segment performs wholesale activities that
 provide value to gas distribution utilities, marketers and pipelines.  The
 Company owns and operates a natural gas liquids (NGL) peaking facility and
 is active in other asset-based wholesale activities.  In addition, Peoples
 Gas operates a natural gas hub.

The Retail Energy Services segment markets gas and electricity and
 provides energy management and other services to retail customers.  In
 addition, Peoples Gas also offers a variety of HVAC related products and
 services to small commercial and residential consumers.

The Oil and Gas Production segment is active in the development and
 production of oil and gas reserves in selected basins in the United States.
 The Company targets on-shore prospects with proved producing oil and gas
 reserves and the potential for enhancement through drilling programs.

The Company is involved in other activities such as district heating
 and cooling and the development of fueling stations for natural gas
 vehicles.  These and other activities do not fall under the above segments
 and are reported in the Other segment.



COMPETITION AND DEREGULATION

Peoples Gas and North Shore Gas are authorized by statute and/or
 certificates of public convenience and necessity to conduct operations in
 the territories they serve.  In addition, these subsidiaries operate under
 franchises and license agreements granted them by the communities they
 serve.  Peoples Gas holds a perpetual, non-exclusive franchise from the
 City.  North Shore Gas' franchises with communities within its service
 territory are of various terms and expiration dates.

Absent extraordinary circumstances, potential competitors are barred
 from constructing competing gas distribution systems in the utility
 subsidiaries' service territories by a judicial doctrine known as the
 "first in the field" doctrine.  In addition, the high cost of installing
 duplicate distribution facilities would render the construction of a
 competing system impractical.

Competition in varying degrees exists between natural gas and other
 fuels or forms of energy available to consumers in Peoples Gas' and North
 Shore Gas' service areas.

On December 16, 1997, the State of Illinois enacted legislation to
 restructure the electric market in Illinois.  Under the legislation,
 approximately one-third of non-residential electric customers, including
 customers with very large loads, were able to purchase electric power from
 the supplier of their choice beginning on October 1, 1999.  All
 non-residential customers will have this choice by December 31, 2000.  All
 residential customers will be given the choice by May 1, 2002.  Customers
 who buy their electicity from a supplier other than the local electric
 utility will be required to pay transition charges to the utility through
 the year 2006.  These charges are intended to compensate the electric
 utilities for revenues lost because of customers buying electricity from
 other suppliers.  The legislation also allows an electric utility to issue
 bonds, in aggregate amounts up to 50% of its Illinois jurisdictional
 capitalization, to be financed by a specific charge to its customers.  An
 electric utility also may transfer up to 15% of its assets to an affiliated
 or unaffiliated entity without approval from the Illinois Commerce
 Commission (Commission).  In return for these and other benefits, electric
 utilities are required to reduce their rates to residential customers.  The
 state's two largest electric utilities, including the utility that serves
 northeastern Illinois, reduced their residential rates by 15% on August 1,
 1998.  In addition, both utilities must further reduce their residential
 rates by 5% on October 1, 2001, and the other must do so on May 1, 2002.
 The legislation does not require electric utilities to divest their power
 generation assets. However, subject to certain capacity restrictions,
 electric utilities can divest assets without Commission approval.  It is
 too early to determine what effects this restructuring of the electric
 market will have on the competitive position of the Company's subsidiaries.

In addition to restructuring the electric market, the legislation
 provides for additional funding for assistance to low-income energy users,
 including customers of the Companys' utility subsidiaries.  The legislation
 creates a fund, financed by charges to electric and gas customers of public
 utilities and participating municipal utilities and electric co-ops, which
 supplements currently available federal energy assistance.

A substantial portion of the gas that Peoples Gas and North Shore Gas
 deliver to their customers consists of gas that the subsidiaries' customers
 purchase directly from producers and marketers rather than from the
 subsidiaries.  These direct customer purchases have little effect on net
 income because the utilities provide transportation service for such gas
 volumes and recover margins similar to those applicable to conventional gas
 sales.

A pipeline may seek to provide transportation service directly to
 end-users.  Such direct service by a pipeline to an end-user would bypass
 the local distributor's service and reduce the distributor's earnings.
 However, none of the subsidiaries' pipeline suppliers has undertaken any
 service bypassing the subsidiaries.  Both utility subsidiaries have a bypass
 rate approved by the Commission which allows the utilities to renegotiate
 rates with customers that are potential bypass candidates.

Through its Retail Energy Services segment, the Company is involved in
 the marketing of gas and electricity to retail customers.  The Company has
 seen substantial growth in its nearly three years of full operation.  As one
 of the three largest energy suppliers in the state of Illinois, the Company
 now sells over 20% of all the gas to eligible retail customers.  Competition
 in this arena comes from utility affiliates, purchased by, some larger
 marketers, and a number of smaller marketers as the market continues to
 expand.  Through its positive name recognition, acquisition of customer
 contracts and strategic marketing efforts towards higher margin customers,
 the Company aims to capture major regional market share of this business.
 The business climate is volatile with many companies entering and exiting
 the business.

SALES AND RATES

Peoples Gas and North Shore Gas sell natural gas having an average
 heating value of approximately 1,000 British thermal units (Btus) per cubic
 foot.*  Sales are made and service rendered by Peoples Gas and North Shore
 Gas pursuant to rate schedules on file with the Commission containing
 various service classifications largely reflecting customers' different uses
 and levels of consumption.  The Gas Charge is determined in accordance with
 the provisions in Rider 2, Gas Charge, to recover the costs incurred by
 Peoples Gas and North Shore Gas to purchase, transport, manufacture, and
 store gas supplies.  The level of the Gas Charge under both subsidiaries'
 rate schedules is adjusted monthly to reflect increases or decreases in
 natural gas supplier charges, purchased storage service costs, transportation
 charges and liquefied petroleum gas costs.  In addition, under the tariffs
 of Peoples Gas and North Shore Gas, the difference for any month between
 costs recoverable through the Gas Charge and revenues billed to customers
 under the Gas Charge is refunded to or recovered from customers.  Consistent
 with these tariff provisions, such difference for any month is recorded
 either as a current liability or a current asset (with a contra entry to Gas
 Costs).  (See Note 1L of the Notes to Consolidated Financial Statements.)

The business of the Company's utility subsidiaries is influenced by
 seasonal weather conditions because a large element of the subsidiaries'
 customer load consists of space heating.  (For discussion of the effects of
 weather, see Other Matters in Item 7.)  Therefore, weather-related deliveries
 can have a significant positive or negative impact on net income.  (For
 discussion of the effect of the seasonal nature of gas revenues on cash flow,
 see Liquidity in Item 7.)

The basic marketing plans of Peoples Gas and North Shore Gas are to
 maintain their existing shares in all market segments and develop
 opportunities emerging from changes in the utility environment and
 technological equipment advances for new, expanded, or current natural gas
 applications, including cogeneration, prime movers, natural gas-fueled
 vehicles and natural gas air-conditioning.

STATE LEGISLATION AND REGULATION

Peoples Gas and North Shore Gas are subject to the jurisdiction of
 and regulation by the Commission, which has general supervisory and
 regulatory powers over practically all phases of the public utility business
 in Illinois, including rates and charges, issuance of securities, services
 and facilities, systems of accounts, investments, safety standards,
 transactions with affiliated interests, as defined in the Illinois Public
 Utilities Act, and other matters.





*  All volumes of natural gas set forth in this report are stated on a
 1,000 Btu (per cubic foot) billing basis.

(100 cubic feet = 1 therm; 10 therms = 1 Dekatherm - Dth)

FEDERAL LEGISLATION AND REGULATION

The Company is a holding company as defined in the Public Utility
 Holding Company Act of 1935 (Act).  By Order entered on December 6, 1968
 (Holding Company Act Release No. 16233), the Securities and Exchange
 Commission, pursuant to Section 3(a)(1) of the Act, exempted the Company and
 its subsidiary companies as such from the provisions of the Act, other than
 Section 9(a)(2) thereof.

Most of the gas distributed by Peoples Gas and North Shore Gas is
 transported to the utilities' distribution systems by interstate pipelines.
 In their provision of gas sales services (gathering, transportation and
 storage services, and gas supply), pipelines are regulated by the Federal
 Energy Regulatory Commission (FERC) under the Natural Gas Act and the
 Natural Gas Policy Act of 1978.  (See "Sales and Rates" and "Current Gas
 Supply" in Item 1.)

Peoples Gas' operation of its natural gas hub is subject to the
 jurisdiction of and regulation by the FERC, which has authority over the
 rates, terms and conditions of the hub services.

ENVIRONMENTAL MATTERS

The Company and its subsidiaries are subject to federal and state
 environmental laws.  Peoples Gas and North Shore Gas are conducting
 environmental investigations and work at certain sites that were the
 location of former manufactured gas plant operations.  (See Note 3A of the
 Notes to Consolidated Financial Statements.)  In addition, North Shore Gas
 has received a demand for payment of environmental response costs at a former
 mineral processing site in Denver, Colorado.  (See Note 3B of the Notes to
 Consolidated Financial Statements.  Also see Note 18 "Events (Unaudited)
 Subsequent to the Auditors' Report Dated October 29, 1999.")

CURRENT GAS SUPPLY

Peoples Gas and North Shore Gas have each entered into various
 long-term and short-term firm gas supply contracts.  When used in conjunction
 with contract peaking and contract storage, Peoples Gas' company-owned
 storage, and the peak-shaving facilities of the utilities, such supply is
 deemed sufficient to meet current and foreseeable peak and annual market
 requirements.

Although the Company believes North American supply to be sufficient
 to meet U.S. market demands for the foreseeable future, it is unable to
 quantify or otherwise make specific representations regarding national
 supply availability.

The following tabulation shows the expected design peak-day
 availability of gas in thousands of dekatherms (MDth) during the 1999-2000
 heating season for Peoples Gas and North Shore Gas:

Peoples Energy Sevices purchased the majority of the natural gas
 required to serve its retail customers from a single wholesale supplier,
 with the remaining requirements met through purcahses from a small number of
 other suppliers.  The gas supply agreement with the major supplier extends
 through March 31, 2002.  The agreement applies to deliveries to serve retail
 customers in the northern Illinois market area.  All gas is delivered to
 Peoples Energy Services at the Chicago city gates for those local
 distribution companies.  Peoples Energy Services does not contract for
 interstate pipeline capacity in connection with purchases from the maajor
 supplier.





ITEM 2.  Properties

All of the principal plants and properties of Peoples Gas and North
 Shore Gas have been maintained in the ordinary course of business and are
 believed to be in satisfactory operating condition.  The distribution
 facilities serve the City and other areas in northeastern Illinois.
 Peoples Gas owns and operates an underground gas storage reservoir and an
 LNG plant at Manlove Field located near Champaign, Illinois.  Peoples Gas
 also owns a transmission system that transports gas from Manlove Field to
 Chicago.  The underground storage reservoir and LNG plant also serve North

ITEM 7.  Management's Discussion and Analysis of
 Results of Operations and Financial Condition



RESULTS OF OPERATIONS

Representative of its progress towards becoming a more diversified
 energy company, Peoples Energy is reporting, for the first time, year-end
 operating income and equity investment income for each of its six business
 segments: Gas Distribution, Power Generation, Midstream Services, Retail
 Energy Services, Oil and Gas Production and Other.  (See Note 2 of the Notes
 to Consolidated Financial Statements.)  North Shore Gas is active in the Gas
 Distribution segment only.  Peoples Gas' main activity is in the Gas
 Distribution segment but is also involved in activity reported in the
 Midstream and Retail Energy Services segments.

Net Income

In 1999, net income for the Company increased $13.2 million to $92.6
 million, due primarily to an increase in operating income and equity
 investment income from diversified business segments, the elimination of the
 decommissioning reserve associated with the 1995 retirement of Peoples Gas'
 synthetic natural gas plant and a state tax refund.  These effects were
 partially offset by lower operating income from the gas distribution
 segment.

In 1998, net income for the Company decreased $19.0 million to $79.4
 million, principally as a result of weather that was 18 percent warmer than
 the prior year.  Increases in costs associated with outside professional
 services and advertising expense also contributed to the decline in net
 income.  These effects were offset, in part, by increased earnings from
 diversified business segments, a reduction in the provision for
 uncollectible accounts, and lower group insurance expense.

In 1999, net income for Peoples Gas increased $9.8 million to $78.2
 million, primarily as a result of the elimination of the decommissioning
 reserve associated with the 1995 retirement of its synthetic natural gas
 plant, a state income tax refund, and an increase in income from hub
 activities.

In 1998, net income for Peoples Gas decreased $16.7 million to $68.4
 million, due primarily to weather that was warmer than the prior year.
 Increases in the costs associated with outside professional services and
 depreciation expense also contributed to the decline of net income.  These
 effects were partially offset by decreases in the provision for
 uncollectible accounts and labor costs.

In 1999, net income for North Shore Gas decreased by $493,000 to $12.5
 million, primarily as a result of increases in operation and maintenance
 expenses and depreciation expense, partially offset by a state income tax
 refund.

In 1998, net income for North Shore Gas decreased $1.8 million to
 $13.0 million, principally as a result of weather that was warmer than the
 prior year.  Increases in labor costs and depreciation expense also
 contributed to the decline in net income.  These effects were offset in part
 by a decrease in pension expense and a decline in the costs associated with
 outside professional services.



A summary of variations affecting income between years is presented
 below, with explanations of significant differences following:

Gas Distribution Segment

The Company's core business is the distribution of natural gas.  Its
 two regulated utilities purchase, distribute, sell and transport natural
 gas to approximately 1 million retail customers through a 6,000 mile
 distribution system serving the City of Chicago and 54 communities in
 northeastern Illinois.  The Company also owns a storage facility in central
 Illinois and a pipeline which connects the facility and five major pipeline
 suppliers to Chicago.

Gross revenues of Peoples Gas and North Shore Gas are affected by
 changes in the unit cost of the utilities' gas purchases and do not include
 the cost of gas supplies for customers who purchase gas directly from
 producers and marketers rather than from the utilities.  The unit cost of
 gas does not have a direct significant effect on operating income because
 of the utilities' tariffs that provide for dollar-for-dollar recovery of gas
 costs.  (See Note 1L of the Notes to Consolidated Financial Statements.

In 1999, operating revenues for the Company decreased compared to
 1998 due mainly to lower unit costs of gas.  Operating income decreased
 $5.4 million to $154.9 million in 1999, due chiefly to a decrease in gas
 deliveries.  Also negatively affecting operating income were lower pension
 credits and an increase in depreciation expense due to depreciable property
 additions.  Partially offsetting these effects were reductions in labor,
 group insurance expense and the provision for uncollectible
 accounts.

In 1998, operating revenues for the Company decreased from the
 previous year due primarily to weather being 18 percent warmer.  Operating
 income decreased $29.4 million to $160.2 million in 1998, due mainly to the
 effect of warmer weather.  Also contributing to the decrease in operating
 income was an increase in the cost of outside professional services.
 Offsetting these negative impacts were a lower provision for uncollectible
 accounts and a reduction in group insurance expense.

In 1999, operating income decreased $3.9 million to $130.4 million
 for Peoples Gas due primarily to increased customer conservation, a prior
 period accrual adjustment, a decrease in other operating revenues, lower
 pension credits and an increase in depreciation expense due to depreciable
 property additions.  Partially offsetting these effects were reductions in
 labor costs, group insurance expense and the provision for uncollectible
 accounts.

In 1998, operating income for Peoples Gas decreased $26.6 million to
 $134.3 million, due chiefly to lower gas deliveries resulting from the
 effects of warmer weather.  Also contributing to this negative effect were
 increases in outside professional services and depreciation expense due
 largely to depreciable property additions.  Partially offsetting these
 effects were reductions in group insurance expense, labor costs and higher
 pension credits.

In 1999, operating revenues for North Shore Gas decreased $1.5 million
 to $24.4 million, due mainly to a decrease in gas deliveries.
 Also negatively affecting operating income were lower pension credits and
 increases in labor costs and depreciation expense due primarily to
 depreciable property additions.

In 1998, operating income for North Shore Gas decreased $2.8 million
 to $25.9 million, due primarily to a decrease in gas deliveries due mainly
 to the effects of warmer weather.  Also negatively affecting operating
 income were increases in labor costs and depreciation expense due mainly to
 depreciable property additions.  These negative effects were partially
 offset by increased pension credits and lower costs associated with outside
 professional services.

The Company's objectives for this segment center on continuous
 improvement, technological advancements and customer service.  Initiatives
 for fiscal 2000 include the implementation and enhancement of the C-first
 customer information system, the near completion of the SureRead(sm)
 automatic meter reading system, gas supply optimization through an agreement
 with Enron North America Corp., and continued pursuit of performance-based
 rates.  The Company is targeting returns on equity of 12% for fiscal 2000
 and has no plans to file rate cases.  Operating revenues are expected to
 increase due to normal weather and increased gas prices.  Segment operating
 income is expected to improve due to normal weather, partially offset by
 increased labor and depreciation expenses.

Power Generation Segment

The Company is engaged in the development, construction, operation,
 and ownership of gas-fired electric generation facilities for sales to
 electric utilities and marketers.  The Company and Dominion Resources Inc.
 are equal investors in Elwood Energy, which owns and operates a 600-megawatt
 peaking facility near Chicago, Illinois.

Operating income and equity investment income amounted to $6.9 million
 in 1999, mostly as a result of the Company's investment in Elwood Energy.
 Income from this partnership, $8.5 million, was partially offset by labor
 and other costs associated with activities related to this project and other
 potential power generation projects.

The Company's objective is to own and operate more than 1,000
 megawatts of peaking capacity.  It is pursuing regional opportunities in and
 near the City of Chicago as well as considering the expansion of the Elwood
 facility, which has received regulatory approvals for a total of 3,100
 megawatts in generating capacity.  The Company expects equity investment
 income for fiscal 2000 to increase substantially due to the full year impact
 of Elwood.  Annual revenues from the two contracts for the entire plant
 capacity are recognized based on utilization of the plant.

Midstream Services Segment

The Company performs wholesale activities that provide value to gas
 distribution utilities, marketers and pipelines.  The Company operates a
 natural gas hub, owns and operates a natural gas liquids (NGL) peaking
 facility and is active in other asset-based wholesale activities.

In 1999, operating income increased $1.6 million to $9.0 million
 compared to 1998, due primarily to an increase in operating revenues
 resulting from increased Peoples Gas hub activity and additional capacity
 revenue from the NGL peaking facility.  Partially offsetting these increases
 was lower operating income from wholesale marketing.

In 1998, operating income increased $5.3 million over 1997, to $7.4
 million due mainly to increased revenue from wholesale marketing, Peoples
 Gas hub activity, and the NGL peaking facility.  These impacts on operating
 income were partially offset by the increased cost of energy sold.

In 1999 and 1998, operating income for Peoples Gas, relative to this
 segment, increased $2.7 million to $6.0 million and $1.6 million to $3.3
 million, respectively, resulting from increased hub activity.

The Company's objective is to become the primary player in the Midwest
 market center, developing additional hub services such as storage,
 transportation and title tracking while pursuing an exchange-traded Chicago
 contract.  A recent agreement with Enron North America Corp. is expected to
 enable the Company to expand its Chicago hub and pursue wholesale marketing
 opportunities.  The Company intends to market additional capacity from its
 existing NGL peaking facility and pursue the development of an additional
 gas peaking facility.  The Company will also be active in the development of
 regional wholesale projects such as its proposed pipeline from the Midwest
 market center to Wisconsin.

Retail Energy Services Segment

The Company markets gas and electricity and provides energy management
 and other services to retail customers.

In 1999, the operating loss of $3.6 million was $408,000 less than in
 1998 for the Company, due mainly to an increase in operating revenues from
 retail gas sales.  Partially offsetting this improvement were increases in
 the cost of energy sold and higher operating costs, due to growth in
 operatrions infrastructure and the development of a retail electric
 business.

In 1999, Peoples Gas reflected an operating loss for this segment of
 $365,000 due to costs associated with Peoples Home Services a business unit
 providing home furnance and air conditioning maintenance services.  Peoples
 Gas' involvement in this segment began in fiscal 1999.

In 1998, operating losses for the Company increased by $1.8 million
 from the prior year, to $4.0 million due chiefly to increases in the cost of
 energy sold, higher labor costs and increased costs of outside professional
 services.  These negative impacts were partially offset by increased
 revenues from retail gas sales.

The Company's objective is to capture major regional market share in
 energy sales.  It will develop proprietary products as it participates in
 the Illinois electric and gas unbundling process and will continue to build
 the necessary infrastructure as it grows through acquisitions and direct
 marketing efforts.  Recently certified by the Illinois Commerce Commission
 (Commission) as an Alternative Retail Electric Supplier (ARES) in Illinois,
 the Company is one of the first ARES to provide electric products to eligible
 customers in the state.

Oil and Gas Production Segment

The Company is active in the development and production of oil and gas
 reserves in selected basins in the United States.  The Company targets
 on-shore prospects with proved producing oil and gas reserves and the
 potential for enhancement through drilling programs.

In 1999, the first full year of activity, operating income and equity
 investment income increased $2.6 million to $2.2 million, due primarily to
 new investments in oil and gas properties along with successful drilling of
 new wells.

The Company's objective is to become a top-fifty owner of U.S. gas
 reserves with holdings of between 350 to 400 billion cubic feet.  Existing
 oil and gas properties will be developed through drilling and production
 enhancements.  The Company will continue to hedge production in order to
 mitigate price risk and will pursue reserve acquisitions that are consistent
 with its basin strategy.  The Company intends to develop or acquire the
 expertise to operate its properties.

Other Segment

The Company is involved in other activities such as district heating
 and cooling and the development of fueling stations for natural gas
 vehicles.  These and other activities do not fall under the above segments.

The variations for the two reportable periods are primarily
 attributable to fluctuating costs associated with business development
 activities.

Corporate and Adjustments

This category encompasses corporate activities that support the six
 segments, as well as consolidating adjustments.

The variations for the two reportable periods are due to increased
 advertising costs and higher labor costs.

Other Income and Deductions

Other income and deductions for the Company increased $15.5 million to
 $19.8 million in 1999, due mainly to the elimination of the decommissioning
 reserve associated with the 1995 retirement of Peoples Gas' synthetic
 natural gas plant (see Note 8 of the Notes to Consolidated Financial
 Statements) and the interest income on a state income tax refund.

In 1998, other income and deductions for the Company decreased
 $844,000 to $4.3 million, due mainly to a reduction in miscellaneous
 interest revenues.

In 1999, other income and deductions for Peoples Gas increased by
 $16.8 million to $18.9 million, due primarily to the elimination of the
 decommissioning reserve associated with the 1995 retirement of its synthetic
 natural gas plant, interest income arising from a state income tax refund,
 an increase in the allowance for other funds used during construction and a
 prior period loss on disposition of property.

In 1998, other income and deductions decreased $1.9 million to $2.1
 million for Peoples Gas, due primarily to lower miscellaneous interest
 revenues.  Partially offsetting this effect was an increase in the allowance
 for other funds used during construction.

In 1999, other income and deductions for North Shore Gas increased by
 $234,000 to $648,000, primarily due to interest income arising from a state
 income tax refund.

Interest Expense

Interest expense for the Company increased $966,000 in 1999 due
 primarily to increased interest on short-term debt, offset, in part, by
 increases in capitalized interest expense and the allowance for borrowed
 funds used during construction.

Interest expense increased $217,000 in 1998 for the Company due to
 increased interest on short-term debt and increased interest expense on
 utility budget plan accounts, offset, in part, by an increase in the
 allowance for borrowed funds used during construction.

In 1999, interest expense for Peoples Gas decreased $523,000 to $32.6
 million, primarily due to an increase in the allowance for borrowed funds
 used during construction and to a decrease in interest on long-term debt,
 partially offset by increases in other interest expense, including carrying
 charges on an environmental insurance recovery.

In 1999, interest expense for North Shore Gas decreased by $27,000 to
 $5.2 million, primarily due to a decrease in interest expense on promissory
 notes and interest income on a construction fund, partially offset by an
 increase in carrying charges on an environmental insurance recovery and an
 increase in interest on long-term debt.

Interest expense increased $120,000 to $5.2 million for North Shore
 Gas, due mainly to an increase in interest on promissory notes.

Income Taxes

In 1999, income taxes for the Company increased $7.5 million to $52.6
 million, due mainly to higher pre-tax income.  Fiscal year 1999 also
 includes a tax accrual adjustment for a state income tax refund.
 Income taxes decreased $11.3 million to $45.1 million in 1998, due to lower
 pre-tax income.  Fiscal years 1998 and 1997 reflect other tax accrual
 adjustments.  Variations between periods for these adjustments are minimal.

In 1999, income taxes increased for Peoples Gas $5.9 million to
 $44.1 million due primarily to higher pre-tax income and to a state income
 tax refund.  In 1998, income taxes decreased $10.1 million to $38.2 million,
 due mainly to lower pre-tax income.

In 1999, income taxes for North Shore Gas decreased $728,000 to
 $7.4 million, primarily due to lower pretax income and to a state income tax
 refund.  In 1998, income taxes decreased $1.1 million to $8.1 million, due
 mainly to lower pre-tax income.

Fiscal 2000 Outlook

The Company expects its earnings per share for fiscal 2000 to fall between $2.65 and $2.75, assuming normal weather.  The financial target for the gas distribution segment is to achieve a 12% return on common equity.  The target for the diversified
business segments is to achieve between 12% and 16% of total earnings, based on an EBIT range between $25 and $35 million.

Other Matters

Effect of Weather.  Weather variations affect the volumes of gas delivered for heating purposes and, therefore, can have a significant positive or negative impact on net income, cash position and coverage ratios of the Company.  Weather in
fiscal years 1999 and 1998 was warmer than normal by 14% and 15%, respectively.  In order to mitigate the effect of substantially warmer weather, Peoples Energy has purchased a five-year weather insurance policy.  The weather insurance program, beginning
in fis
ny to protect earnings when weather is more than 8% warmer than normal.  The Company will continue to retain all upside revenue potential when weather is colder than normal.

Accounting Standards. In fiscal 1999, Peoples Energy and its subsidiaries adopted Statement of Financial Accounting Standard (SFAS) Nos. 130, 131, and 132.  Refer to Note 1P of the Notes to Consolidated Financial Statements for a further
explanation.

In March 1998, the American Institute of Certified Public Accountants (AICPA) issued Statement of Position 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use."  This statement provides guidance on
accounting for the costs of computer software developed or obtained for internal use.  The statement will be adopted in fiscal year 2000.  The Company does not expect the application of this standard to have a material effect on its financial condition or
r

In June 1998, as amended on May 19, 1999, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities."  This statement establishes accounting and reporting standards for
derivative financial instruments, including certain derivative instruments embedded in other contracts, and for hedging activities.  It requires that an entity recognize all derivatives as either assets or liabilities on the consolidated balance sheet and
meas
alue.  The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and resulting designation.

Changes in the fair value of derivatives will be recognized in the current period earnings, unless specific hedge accounting criteria are met.  If a transaction qualifies for hedge accounting, the gains and losses of derivatives will offset the
related results of the hedged item in the current period's income statement.  SFAS No. 133 requires that formal documentation be maintained and that the effectiveness of the hedge be assessed quarterly.  The statement must be adopted no later than the
Company'
ts current risk management strategies, the Company does not expect the adoption of this standard to have a material effect on its financial condition or results of operations.  The Company cannot predict how financial results may be affected by
application of this standard toward any new risk management strategies it may adopt in the future.

COMPETITION AND DEREGULATION

Competition in varying degrees exists between natural gas and other fuels or forms of energy available to consumers in the Peoples Gas and North Shore Gas service areas.

On December 16, 1997, the State of Illinois enacted legislation to restructure the electric market in Illinois.  Under the legislation, approximately one-third of non-residential electric customers, including customers with very large loads, were
able to purchase electric power from the supplier of their choice beginning on October 1, 1999.  All non-residential customers will have this choice by December 31, 2000.  All residential customers will be given this choice by May 1, 2002.  Customers who
buy

In addition to restructuring the electric market, the legislation provides for additional funding for assistance to low-income energy users, including customers of the Company's utility subsidiaries.  The legislation creates a fund, financed by
charges to electric and gas customers of public utilities and participating municipal utilities and electric co-ops, which supplements currently available federal energy assistance.

LIQUIDITY

Source of Funds

The Company has access to outside capital markets and to internal sources of funds that together provide sufficient resources to meet capital requirements.  It does not anticipate any changes that would materially alter its current liquidity position
 .

Due to the seasonal nature of gas usage, a major portion of the utilities' cash collections occurs between December and May.  Because of timing differences in the receipt and disbursement of cash and the level of construction requirements, the
utility subsidiaries may borrow on a short-term basis.  Short-term borrowings are repaid with cash from operations, other short-term borrowings, or refinanced on a permanent basis with debt or equity, depending on market conditions and capital structure
conside

Credit Lines

The Company has lines of credit of $170.0 million.  At September 30, 1999, the Company had unused credit available from banks of $54.8 million.  The utility subsidiaries have lines of credit of $119.0 million.  At September 30, 1999, the utility
subsidiaries had unused credit available from banks of $102.9 million.  (See Note 13 of the Notes to Consolidated Financial Statements.)

Cash Flow Activities

Net cash provided by operating activities for the Company increased $24.9 million in fiscal 1999, due chiefly to an increase in net income and changes in other assets and accounts payable.  Partially offsetting these items were changes in net
receivables, deferred credits and other liabilities and gas costs recoverable.

In fiscal 1998, net cash provided by operating activities for the Company decreased $8.1 million, primarily due to changes in deferred credits and other liabilities and net income.  These items were partially offset by changes in material and
supplies and net receivables.

Net cash used in investing activities for the Company for 1999 and 1998 largely represents the level of capital expenditures and investments (capital spending) for the Company and its subsidiaries in the respective years.

In 1999, net cash provided by financing activities for the Company increased $98.0 million, due mainly to increased short-term borrowing by the Company to fund activities of its diversified business segments and the issuance of long-term debt by
the utilities, offset by the retirement of long-term debt and the payment of dividends.

In fiscal 1998, net cash used in financing activities for the Company increased $12.0 million, due largely to the issuance of new shares of common stock through the Direct Purchase and Investment Plan and increased borrowing for the gas
distribution segment.  These effects were offset, in part, by the payment of dividends.

Net cash provided by operating activities for Peoples Gas increased $33.9 million in fiscal 1999, due primarily to changes in deferred charges, accounts payable, and gas in storage, as well as an increase in net income, partially offset by changes
in other deferred credits and other liabilities, receivables - net, and accrued unbilled revenues.

In 1998, net cash provided by operating activities for Peoples Gas decreased by $11.1 million,  due primarily changes in deferred charges,  net income, current regulatory assets and gas costs recoverable, partially offset by changes in receivables
- net, other deferred credits and other liabilities, and accrued taxes.

Net cash used in investing activities by Peoples Gas increased $ 26.8 million in fiscal 1999, due primarily to an increase in capital spending and the prior year's receipt of cash from temporary cash investments.

In 1998, net cash used in investing activities by Peoples Gas decreased $12.6 million, due primarily to cash received from temporary cash investments, partially offset by an increase in capital expenditures.

Net cash used in financing activities by Peoples Gas decreased $8.8 million in fiscal 1999, primarily due to a reduction in dividends paid on common stock, partially offset by the retirement of long-term debt.

In 1998, net cash used in financing activities by Peoples Gas increased by $17.9 million,  due primarily to an increase in dividends paid on common stock, partially offset by an increase in short-term borrowings.

Net cash provided by operating activities for North Shore Gas decreased $7.8 million in fiscal 1999, due primarily to changes in other deferred credits and other liabilities, receivables - net, deferred income taxes and investment tax credits -
net, and gas costs recoverable, partially offset by changes in  deferred charges and accrued taxes.

In 1998, net cash provided by operating activities for North Shore Gas increased $8.1 million,  due primarily changes in other deferred credits and other liabilities, payables, and gas sales revenue refundable, partially offset by changes in
deferred charges and in current regulatory assets.

Net cash used in investing activities by North Shore Gas in fiscal 1999 increased $ 11.4 million due to an increase in capital expenditures and to a temporary cash investment.

In 1998, net cash used in investing activities by North Shore Gas decreased $1.1 million, due to a decrease in capital expenditures.

Net cash used in financing activities by North Shore Gas decreased $10.5 million in fiscal 1999, due to the issuance of long-term debt, a reduction in dividends paid on common stock, and the prior year's repayment of short-term debt, partially
offset by the retirement of long-term debt.

In 1998, net cash used in financing activities by North Shore Gas increased by $4.8 million, due to an increase in dividends paid on common stock and the repayment of short-term borrowings.

Indenture Restrictions

North Shore Gas' indenture relating to its first mortgage bonds contains provisions and covenants restricting the payment of cash dividends and the purchase or redemption of capital stock. At September 30, 1999, such restrictions amounted to $11.6
million out of North Shore Gas' total retained earnings of $72.1 million.  (See Note 4 of the Notes to Consolidated Financial Statements.)



Interest Coverage

The fixed charges coverage ratios for Peoples Gas and North Shore Gas for fiscal 1999, 1998 and 1997 are as follows:



|Fiscal years    | 1999 | 1998 | 1997
|--------------- | ---- | ---- | ----
|Peoples Gas     | 4.59 | 4.15 | 5.01
|North Shore Gas | 4.77 | 5.07 | 5.74

The increase in the ratio for Peoples Gas in 1999 reflects higher pre-tax income and slightly higher interest expense.  The decrease in the ratio for North Shore Gas in 1999 is due to lower pre-tax income and higher interest expense.  The decrease
in the ratios for both companies in 1998 reflects lower pre-tax income, primarily due to warmer weather.

Debt Ratings

The Company has been assigned corporate credit ratings of A2 by Moody's Investors Service and A+ by Standard & Poor's Corporation.  The commercial paper ratings are P-1 and A-1, respectively.

The long-term debt of both gas distribution utility subsidiaries
 is rated Aa2 by Moody's Investors Service and AA- by Standard & Poor's Corporation.  Moody's upgraded its ratings from Aa3 in November 1997.  Standard & Poor's Corporation last changed its ratings in 1985.  The commercial paper of both
subsidiaries has the top rating from the major rating agencies.

Environmental Matters

The Company's gas distribution utility subsidiaries are conducting environmental investigations and work at certain sites that were the location of former manufactured gas operations.  (See Note 3A of the Notes to Consolidated Financial Statements.)

In 1994, North Shore Gas received a demand from a responsible party under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA), for reimbursement, indemnification and contribution for response costs
incurred at a former mineral processing site in Denver, Colorado.  North Shore Gas filed a declaratory judgment action asking the court to declare that North Shore Gas is not liable for response costs relating to the site.  The defendant filed a
counterclai
 District Court's decision and remanded the case for determination of what liability, if any, the former entity has and therefore North Shore Gas has for activities at the site.  (See Note 3B of the Notes to Consolidated Financial Statements.  Also see
Note 18 "Events (Unaudited) Subsequent to the Auditors' Report Dated October 29, 1999.")

Year 2000 Readiness

Peoples Energy, Peoples Gas and North Shore Gas began their efforts to assess the Year 2000 readiness of their mainframe computer systems in March 1996.  Peoples Energy and North Shore Gas obtain their information technology services from Peoples
Gas.  The following discussion applies to Peoples Energy, Peoples Gas and North Shore Gas.

Peoples Energy has developed a comprehensive Year 2000 readiness plan that incorporates all of its information technology systems,
 including computer hardware and software, and its embedded systems equipment, including telecommunications equipment.  The plan also includes a review by the Company of the Year 2000 compliance efforts of its key suppliers and customers and Year 2000
contingency planning.
  The Company-wide Year 2000 effort includes the Company's wholly owned subsidiaries, as well as various joint ventures, and utilizes a combination of consultants and employees of the Company's subsidiaries.

For all internal information technology systems developed by the Company, Year 2000 readiness efforts proceed through the following phases: inventory, assessment, remediation (which includes replacement where appropriate), testing, and
implementation.  Rather than completing each phase for all systems prior to proceeding to the next phase, the Company progresses through all phases on a system-by-system basis, gradually implementing each compliant system.  When a fully-tested application
has been impl

Of the Company's mainframe applications, 29 of 38 applications have been fully remediated, tested and implemented, and nine have been (or are in the process of being) eliminated.  Additionally, all mainframe system modules and non-mainframe
applications, spreadsheets and interfaces have been remediated and tested.

As part of its Year 2000 Project, the Company has also contacted the vendors of its licensed or purchased hardware and software to determine the Year 2000 compliance status of their products and has remediated or eliminated non-compliant vendor
products as appropriate.  (Methods of remediating vendor products include installing product upgrades or replacements or developing reasonable procedures to work around readiness issues.)  The Company also has tested its desktop computer inventory and
believes

The Company has contracted with a consultant that has significant utility and engineering expertise to assist with its Year 2000 readiness efforts for embedded systems.  The Company has completed an inventory of all equipment containing embedded
systems, including telecommunications equipment and facilities, and has assessed the Year 2000 compliance status of the equipment.  The Company has remediated any equipment identified as not Year 2000 ready and has completed testing and implementation.

The Company has a written contingency plan to address risks to the Company created by the Company's or third parties' systems and embedded technology in the event such systems or technology prove not to be Year 2000 compliant.  The plan covers all
critical processes and will be maintained and adjusted as necessary on an ongoing basis.

The Company has contacted key suppliers to determine their Year 2000 compliance efforts.  It is in the process of following up with certain critical suppliers for contingency planning purposes.  The Company has also contacted certain of its major
customers to determine their Year 2000 readiness.

Essential elements of the Company's business are dependent on certain key third parties (for example, interstate pipeline companies, natural gas suppliers, banks, electric utilities and telecommunication companies).  A material failure by any such
key third party could significantly disrupt the Company's business.  With respect to operations over which it has direct control, management perceives that the most significant potential risks in the event that a Year 2000 problem causes one or more
systems

The Company currently estimates that it will incur expenses of approximately $1.2 million through March 31, 2000 to complete its Year 2000 compliance efforts, in addition to the $7.5 million already incurred through September 30, 1999.  Management
does not expect the cost of the Company's Year 2000 compliance efforts to have a material adverse impact on the financial position or results of operations of the Company.



Market Risk Management

Commodity Price Risk. The Company uses market risk sensitive financial instruments, including futures, forward contracts, and derivatives such as swaps and options, to manage its exposure to certain commodity price risks in its
subsidiaries' operations.  These risks occur because of the changing prices of natural gas, power, crude oil, ethane, and propane.  The Company's policy for risk management activities stipulates that such financial instruments are only to be used for
hedging purposes.

The Company's gas distribution utility subsidiaries are not currently exposed to market risk caused by changes in commodity prices.  This is due to current Illinois rate regulation, which allows for all reasonably incurred costs of natural gas to
be recovered from the utilities' customers through the operation of the utilities' Gas Charges.  However, the Company entered into contracts to fix prices for less than 1% of Peoples Gas' gas supplies.  Any gains or losses from financial trades are
deferred

Investments by the Company's diversified business segments are subject to
 a thorough analysis of related market risk and an acceptable plan for each
 investment is formulated to manage this risk.  After a risk management program
 for the investment is approved, both the operating unit's and the Company's
 senior management are kept apprised of any remaining market risk through
 daily mark-to-market reports.

The Company has working interests in natural gas and crude oil
 producing properties.  Using swaps, approximately 85% of the production for
 calendar year 2000 is hedged, thereby removing market risk on that portion of
 the output.  Price movements in natural gas and crude oil swaps and futures are
 highly correlated to any price changes in the underlying physical commodities.
  Therefore, a loss in the market value of the hedged commodity would be
 substantially offset by an equal gain in value resulting from the financial transaction.  As of September 30, 1999, the exposure from non-hedged production was immaterial to the
 consolidated financial statements.  A sensitivity analysis has been prepared
 to estimate the Company's price exposure to the market risk of its physical natural gas and oil reserves and related financial instruments used to mitigate the price exposure.
  As of September 30, 1999, an instantaneous 10% adverse movement in the
 Nymex forward curve for natural gas and oil would have reduced future earnings
 before income taxes by approximately $840,000.

The Company sells fixed price and variable priced products as part of its retail energy services.  These contracts call for physical delivery and can not be settled financially.  Risk is reduced through the use of fixed price supplier contracts and
storage assets.  As of September 30, 1999, exposure from these activities was not material.

The Elwood facility is a gas-fired electric generating peaking facility.  Elwood has agreed to sell all of the facility's generation capacity and energy produced at fixed demand and commodity charges under multi-year contracts.  Therefore, Elwood
has no price risk on its power sales.  However, it does bear fuel price risk when natural gas prices exceed its targeted weighted average cost of gas (WACOG).  The partnership has implemented a comprehensive risk management program that is intended to
reduce
 cash flow and extract maximum value from its investment.  The program includes the purchase of gas supply at or near targeted WACOG prices, limits to minimize the threat of loss through market movements, daily review of price exposure and frequent senior
management review.  As of September 30, 1999, Elwood had no open financial positions related to its risk management strategy.

The Company is also exposed to credit risk when a hedging transaction counterparty or supplier defaults on a contract to pay for or deliver product at agreed-upon terms and conditions.  To mitigate this risk, the Company has established procedures
to determine and monitor the creditworthiness of counterparties.  Transactions are executed only with counterparties having strong credit ratings.  Controls are also in place to limit dollar exposure and transaction term based upon creditworthiness.  The
Co
 the counterparties to fail to meet their contractual obligations with these controls in place.

Interest Rate Risk. Interest rate risk generally is related to the Company's and its gas distribution subsidiaries' outstanding debt.  A sensitivity analysis methodology is being utilized to determine potential loss of future earnings, fair
values, or cash flows from market risk sensitive instruments over a selected time period due to hypothetical changes in interest rates.

The Company manages its interest rate risk exposure by maintaining a mix of fixed and variable rate debt.  Based on the current mix of $27.0 million in long-term variable rate debt and $129.0 million in short-term borrowings, assuming interest
rates are 10% higher than the rates reported at the end of fiscal 1999, the Company's annualized interest expense would increase by approximately $820,000 before considering the effect of income taxes.

Peoples Gas manages its interest rate risk exposure by maintaining a
 mix of fixed and variable rate debt.  Based on the current mix of $27.0 million
 in long-term variable rate debt and $16.0 million in short-term borrowings,
 assuming interest rates are 10% higher than the rates reported at the end of
 fiscal 1999, Peoples Gas' annualized interest expense would increase by
 approximately $190,000 before considering the effect of income taxes.

CAPITAL RESOURCES

Capital Spending

Capital spending for the Company totaled $229.1 million in 1999, $143.5 million in 1998, and $95.2 million in 1997.

Capital spending for the Company for fiscal 1999 increased $85.6 million from fiscal 1998, due principally to a $57.6 million increase for the Elwood facility which began supplying electricity to customers in July 1999, an increase of $11.8 million
associated with the oil and gas producing properties, an increase of $4.9 million for the SureRead remote automated meter reading system and an additional $6.7 million for the C-first customer information system.

Capital spending for the Company for fiscal 1998 increased $49.7 million from fiscal 1997.  The change is mainly attributable to $38.0 million in diversified business segment projects, primarily consisting of $15.5 million for the Elwood facility
and $16.0 million for the acquisition of oil and gas producing properties, and a $10.0 million increase for the C-first customer information system.

Capital spending for Peoples Gas totaled $111.4 million in 1999, $94.8 million in 1998, and $74.9 million in 1997.

Capital spending for Peoples Gas for fiscal 1999 increased $16.6 million due primarily to an increase of $4.9 million associated with the SureRead remote automated meter reading system and additional spending for the C-first customer information
system of $6.7 million.

In fiscal 1998 capital spending for Peoples Gas increased $19.9 million from the prior year.  The increase is primarily attributable to the new customer information system, offset, in part, by the continuation of a cost containment program.

Capital spending for North Shore Gas totaled $13.8 million in 1999, $10.3 million in 1998, and $11.4 million in 1997.

Capital spending for North Shore Gas increased $3.5 million in 1999. The amount reflects a level that is consistent with the Company's financial goals.

In fiscal 1998 capital spending for North Shore Gas decreased $1.1 million from the prior year.  The reduction reflects North Shore Gas' commitment to its cost containment program.

Fiscal 2000 Outlook

Capital spending is likely to total $200 million in fiscal 2000, but the potential exists for additional spending.  The amount for gas distribution is expected to be less than 1999; the amount for diversified business segments could increase from
the 1999 level.

Financing Activities

Pursuant to notice given to the trustee of the City of Joliet 1984 Series
 C Bonds, due October 1, 1999, which were secured by Peoples Gas' adjustable Rate First and Refunding Mortgage Bonds, Series W, these bonds were redeemed on October 1, 1998.

There are no sinking fund requirements for long-term debt due in fiscal 2000.  (See Notes 14A and 14B of the Notes to Consolidated Financial Statements.)

The Company anticipates that the gas distribution utilities future cash needs for capital expenditures and sinking fund requirements and maturities will be met through internally generated funds, intercompany loans from the Company, borrowing
arrangements with banks or the issuance of short-term debt and periodic long-term financing involving
 equity or the utilities' first mortgage bonds.

The capital needs of the Companys diversified business segments have been met through equity investments, funded, in part, by the issuance of short-term debt.  The Company has established a $150 million commercial paper program for this purpose.
(See Note 13 of the Notes to Consolidated Financial Statements.)

The Company intends to increase its commitments to the diversified business segments.  Capital needs for future investments will be met through equity and short and long-term debt financing based on capital structure consideration and market
conditions, as well as internally generated funds.

FORWARD LOOKING INFORMATION

The MD&A contains statements that may be considered
 forward-looking, such as management's expectations, the statements of the
 Company's financial goals regarding diversified earnings, the effect of
 weather on net income, cash position, source of funds, coverage ratios,
 credit lines and financing activities, market risk, and the insignificant
 effect on income arising from changes in revenue from customers' gas
 purchases from entities other than the gas distribution utility subsidiaries,
 environmental matters, and the discussion concerning Year 2000 compliant systems.  These
 statements speak of the Company's plans, goals, beliefs, or expectations,
 refer to estimates or use similar terms.  Actual results could differ
 materially, because the realization of those results is subject to many
 uncertainties including:

- The future health of the U.S. and Illinois economies;

- The timing and extent of changes in energy commodity prices and interest rates;

- Litigation concerning North Shore Gas' liability for CERCLA response costs relating to a former mineral processing site in Denver, Colorado;

- Regulatory developments in the U.S., or in Illinois and other states where the Company does business;

- Changes in the nature of the Company's competition resulting from industry consolidation, legislative change, regulatory change and other factors, as well as action taken by particular competitors;

- The Company's success in identifying diversified business segment projects on financially acceptable terms and generating earnings from projects in a reasonable time; and

- The ability of various vendors and others with whom the Company interacts to complete Year 2000 systems modification efforts in a timely manner that allows them to continue normal business transactions with the Company without disruption.

Some of these uncertainties that may affect future results are
 discussed in more detail under the captions "Competition & Deregulation,"
 "Sales and Rates," "State Legislation and Regulation,"
 "Federal Legislation and Regulation," "Environmental Matters,"
 and "Current Gas Supply" in "Item 1 - Business" of the
 Annual Report on Form 10-K.  All forward-looking statements included in this
 MD&A are based upon information presently available, and the Company
 assumes no obligation to update any forward-looking stataements.

STATEMENT OF MANAGEMENT'S RESPONSIBILITY



The financial statements and other financial information included in this report were prepared by management, who is responsible for the integrity and objectivity of presented data.  The consolidated financial statements of the Company and its
subsidiaries were prepared in conformity with generally accepted accounting principles and necessarily include some amounts that are based on the best estimates and judgments of management.

The Company maintains internal accounting systems and related administrative controls, along with internal audit programs, that are designed to provide reasonable assurance that the accounting records are accurate and assets are safeguarded from
loss or unauthorized use.  Consequently, management believes that the accounting records and controls are adequate to produce reliable financial statements.

Arthur Andersen LLP, the Company's independent public accountants approved by the shareholders, as a part of its audit of the financial statements, selectively reviews and tests certain aspects of internal accounting controls solely to determine
the nature, timing, and extent of its audit tests.  Management has made available to Arthur Andersen LLP all of the Company's financial records and related data and believes that all representations made to the independent public accountants during its
audit

The Audit Committee of the Board of Directors, comprised of six outside directors, meets periodically with management, the internal auditors, and Arthur Andersen LLP, jointly and separately, to ensure that appropriate responsibilities are
discharged.  These meetings include discussion and review of accounting principles and practices, internal accounting controls, audit results, and the presentation of financial information in the annual report.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. Principles of Consolidation

All subsidiaries are included in the consolidated financial statements.  All significant intercompany transactions have been eliminated in consolidation.  Investments for which the Company's subsidiaries have at least a 20% interest, but less than
a majority ownership, and partnerships in which the Company has less than a majority interest are accounted for under the equity method.  Certain items previously reported for years prior to 1999 have been reclassified to conform with the current-year
presentation.

B. Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent
liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

C. Concentration of Credit Risk

Peoples Gas provides natural gas service to approximately 837,000 customers within the City of Chicago.  North Shore Gas provides natural gas service to about 146,000 customers within approximately 275 square miles in northeastern Illinois.
Peoples Energy Services, the Company's retail energy marketing subsidiary, sells natural gas and electricity to approximately 17,000 customers in northern Illinois.  Credit risk for each Company is spread over a diversified base of residential,
commercial, and industrial customers.  The Company's interest in oil and gas reserves are managed by 32 operators.

Peoples Gas and North Shore Gas encourage customers to participate in their long-standing budget payment programs, which allow the cost of higher gas consumption levels associated with the heating season to be spread over a 12-month billing cycle.
Customers' payment records are continually monitored and credit deposits are required, when appropriate, to minimize uncollectible write-offs.

The counterparties of Elwood Energy consist of an investor-owned utility and an energy trading company, both of which are considered investment grade or higher.  The Company minimizes credit risk by dealing with creditworthy counterparties in
accordance with established credit approval practices and limits.  The Company and Elwood Energy routinely assess the financial strength of their counterparties and may require letters of credit or parental guarantees when the financial strength of a
counterparty is not considered sufficient.

D. Revenue Recognition

Gas sales and transportation revenues are recorded on the accrual basis for all gas delivered during the month, including an estimate for gas delivered but unbilled at the end of each month.  Oil and gas production revenues are accrued based on
estimated monthly production from each well.

E. Property, Plant and Equipment

Property, plant and equipment is stated at original cost and includes appropriate amounts of capitalized labor costs, payroll taxes, employee benefit costs, administrative costs and an allowance for funds used during construction or capitalized
interest as appropriate.

F. Accounts Payable

The Company utilizes controlled disbursement banking arrangements under which certain bank accounts have negative book balances due to checks in transit.  The negative balances are classified as Accounts Payable.

G. Depreciation, Depletion and Amortization

The Company's utility subsidiaries charge the cost of maintenance and repairs of property and minor renewals and improvements of property to maintenance expense.  When depreciable property is retired, its original cost is charged to the accumulated
provision for depreciation.

The provision for depreciation substantially reflects the systematic amortization of the original cost of depreciable property over estimated useful lives on the straight-line method.  Additionally, actual dismantling cost, net of salvage, is
included in the provision for depreciation in the month incurred.  The amounts provided are designed to cover not only losses due to wear and tear that are not restored by maintenance, but also losses due to obsolescence and inadequacy.

Peoples Gas and North Shore Gas' provision for depreciation and amortization, expressed as an annual percentage of the original cost of depreciable property, was 3.7% and 3.1%, respectively, for fiscal years 1999, 1998 and 1997.

In the case of oil and gas producing properties, the Company is amortizing the capitalized costs on an overall units-of-production method based on total estimated proved oil and gas reserves.  The fiscal 1999 and 1998 rate of depletion was $.99 and
$1.23 per equivalent Mcf unit of production, respectively.

Other diversified businesses' depreciable property is amortized over its estimated useful lives.  Gains and losses are recognized at the time of asset sale or disposition.

The consolidated provision for depreciation and amortization, expressed as an annual percentage of the original cost of depreciable property, was 3.6% for fiscal years 1999, 1998 and 1997.

H. Regulated Operations

Peoples Gas' and North Shore Gas' utility operations are subject to regulation by the Commission.  Regulated operations are accounted for in accordance with SFAS No. 71, "Accounting for the Effects of Certain Types of Regulation."  This
standard controls the application of generally accepted accounting principles for companies whose rates are determined by an independent regulator such as the Commission.  Regulatory assets represent certain costs that are expected to be recovered from
customers through the ratemaking process.  When incurred, such costs are deferred as assets on the balance sheet and subsequently recorded as expenses when those same amounts are reflected in rates.

|Total regulatory assets of North Shore Gas                |  |  | $ 21,533    |  | $ 25,102

If all or a reportable portion of the utility operations becomes no longer subject to the provision of SFAS No. 71, a write-off of related regulatory assets and liabilities would be required, unless some form of transition cost recovery continues
through rates established and collected for the remaining regulated operations.



I. Income Taxes

The Company and its subsidiaries follow the liability method of accounting for deferred income taxes.  Under the liability method, deferred income taxes have been recorded using currently enacted tax rates for the differences between the tax basis
of assets and liabilities and the basis reported in the financial statements.  Due to the effects of regulation on Peoples Gas and North Shore Gas, certain adjustments made to deferred income taxes are, in turn, debited or credited to regulatory assets or
liabilities.  (See Note 10C.)

Each utility subsidiary within the consolidated group nets its income tax-related regulatory assets and liabilities.  At September 30, 1999 and 1998, net regulatory income tax assets recorded in Other Assets amounted to $12.0 million and $9.1
million, respectively, while net regulatory income tax liabilities recorded in Other Liabilities equaled $4.7 million and $5.0 million, respectively.

Investment tax credits have been deferred and are being amortized through credits to income over the book lives of related property.

J. Gas in Storage

For Peoples Gas and North Shore Gas, storage injections are priced at the fiscal-year average of costs of supply.  Withdrawals from storage for the utilities are priced on the last-in, first-out (LIFO) cost method.  The estimated current
replacement cost of gas in inventory at September 30, 1999 and 1998 exceeded the LIFO cost by approximately $67.4 million and $99.0 million, respectively.  The retail energy services segment accounts for gas in inventory using the first-in, first-out
(FIFO) method.  The volumes of gas and the associated costs involved are not material.

K. Statement of Cash Flows

For purposes of the balance sheet and the statement of cash flows, the Company considers all short-term liquid investments with maturities of three months or less to be cash equivalents.

Income taxes and interest paid (excluding capitalized interest of $2,608, $646 and $147 for the respective years) were as follows:



|For fiscal years    | Peoples Energy |  | Peoples Gas |  | North Shore Gas
|------------------- | -------------- |  | ----------- |  | ---------------
|Ended September 30, | 1999           |  | 1998        |  | 1997

|Income taxes paid   | $20,502        |  | $19,832     |  | $55,037        
|Interest paid       | 39,778         |  | 37,239      |  | 36,906         

L. Recovery of Gas Costs

Under the tariffs of Peoples Gas and North Shore Gas, all reasonably incurred gas costs are recoverable from customers.  The difference for any month between costs recoverable through the Gas Charge and revenues billed to customers under the Gas
Charge is refunded to or recovered from customers.  Consistent with these tariff provisions, such difference for any month is recorded either as a current liability or as a current asset (with a contra entry to Gas Costs).

For each gas distribution utility, the Commission conducts annual proceedings regarding the reconciliation of revenues from the Gas Charge and related costs incurred for gas.  In such proceedings, costs recovered by a utility through the Gas Charge
are subject to challenge.  Such proceedings, regarding Peoples Gas and North Shore Gas for fiscal years 1997 and 1999, are currently pending before the Commission.



M. Recovery of Costs of Environmental Activities Relating to Former Manufactured Gas Operations

Peoples Gas and North Shore Gas are recovering the costs of environmental activities relating to the utilities' former manufactured gas operations, including carrying charges on the unrecovered balances, under rate mechanisms approved by the
Commission.  For each utility with such a rate mechanism, the Commission conducts annual proceedings regarding the reconciliation of revenues from the rate mechanism and related costs.  In such proceedings, costs recovered by a utility through the rate
mechanism are subject to challenge.  Such proceedings regarding the companies for fiscal year 1998 are currently pending before the Commission.

N. Hedging Activities

The Company has a formal risk management policy that establishes monitoring and control procedures for the execution, recording and reporting of derivative financial instruments.  The intent of the policy is to utilize risk management trading
solely to minimize risk, and not for any speculative purpose.  The Company may use interest rate swaps, forward rate transactions, commodity futures contracts, options and swaps to hedge the impact of interest rate, price and volume fluctuations related
to its business activities, including price risk related to the geographic location of the commodity (basis risk).

The Company is accounting for all current derivative transactions through hedge accounting.  These derivatives are designated as fair value hedges.  Realized gains or losses from derivative instruments (through maturity or termination of the hedge)
are deferred until the underlying hedged item is sold or matures.  If the Company determines that any portion of the underlying hedged item will not be purchased or sold, the unmatched portion of the instrument is marked to market and any gain or loss is
recognized on the Consolidated Statement of Income.  Recognized gains or losses are recorded on the Consolidated Statement of Income with the underlying hedged item.  As of September 30, 1999 and 1998, the Company had open derivative financial instruments
representing hedges of equivalent natural gas production of 9.3 Bcf and 1.0 Bcf.  At September 30, 1999, the Company had no gain or loss on the Consolidated Balance Sheet.  At September 30, 1998, the Company had deferred gains of $13,000 on the
Consolidated Balance Sheet.

O. Oil and Gas Production Properties

For oil and gas activities, the Company follows the full-cost method of accounting as prescribed by the Securities and Exchange Commission.  Under the full-cost method, all costs directly associated with acquisition, exploration and development
activities are capitalized, with the principal limitation that such amounts not exceed the present value of estimated future net revenues to be derived from the production of proved oil and gas reserves (the full-cost ceiling).  If net capitalized costs
exceed the full-cost ceiling at the end of any quarter, a permanent impairment of the assets is required to be charged to earnings in that quarter.  Such a charge would have no effect on the Company's cash flow.  For fiscal years 1999 and 1998, there was
no such charge to income.

P. Accounting Standards

On October 1, 1998, Peoples Energy and its subsidiaries adopted SFAS No. 130, "Reporting Comprehensive Income."  This Statement establishes the standards for reporting and display of comprehensive income and its components in a full set
of financial statements.  The statement requires that all items that are required to be recognized as components of comprehensive income be reported in a financial statement with equal prominence as the other financial statements.  (See Note 7.)

Peoples Energy and its subsidiaries adopted SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information," effective October 1, 1998.  SFAS No. 131 establishes standards for the way to report selected information
about operating segments in annual financial statements and requires reporting selected information about operating segments in interim financial statements.  The statement requires reporting financial and descriptive information about our reportable
operating segments on a basis that is used internally by management in evaluating segment performance.  The adoption of this standard did not affect results of operations or financial position, but did affect the disclosure of segment information.  (See
Note 2.)

In fiscal 1999, the Company and its subsidiaries adopted SFAS No. 132, "Employers' Disclosures about Pensions and Other Postretirement Benefits."  This statement requires disclosure of new accounting information on changes in plan benefit
obligations and fair values of plan assets.  The adoption of this standard did not affect results of operations or financial position, but did affect the disclosure of pension and other postretirement benefits information.  (See Note 9.)

In June 1998, as amended on May 19, 1999, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities."  This statement establishes accounting and reporting standards for
derivative financial instruments, including certain derivative instruments embedded in other contracts, and for hedging activities.  It requires that an entity recognize all derivatives as either assets or liabilities on the consolidated balance sheet and
measure those instruments at fair value.  The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and resulting designation.

Changes in the fair value of derivatives will be recognized in the current period earnings, unless specific hedge accounting criteria are met.  If a transaction qualifies for hedge accounting, the derivative's gains and losses will offset the
related results of the hedged item in the current period's income statement.  SFAS No. 133 requires that formal documentation be maintained and that the effectiveness of the hedge be assessed quarterly.  The statement must be adopted no later than the
Company's fiscal year 2001.  The Company does not expect the adoption of this standard to have a material effect on its financial condition or results of operations.

2: BUSINESS SEGMENTS

The Company is presenting below information about its operating segments for the fiscal years 1999, 1998 and 1997, according to SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information," which was adopted this
year.  The Company has six business segments: Gas Distribution, Power Generation, Midstream Services, Retail Energy Services, Oil and Gas Production, and Other.  Operating income also includes the effect of corporate activities and consolidating
adjustments.  North Shore Gas is active in the Gas Distribution segment only.  Peoples Gas' main activity is the Gas Distribution segment but is also involved in activity reported in the Midstream and Retail Energy Services segments.

The Company has determined its business segments based on regulation plus a delineation based on type of product or services and activity related to those products or services, such as production versus marketing of natural gas.  These segments are
consistent with how the Company's Strategic Planning Committee develops overall strategy for the Company.  The financial performance of each segment is evaluated based on its operating income and equity investment income before interest expense, other
income and deductions, and income taxes.  The accounting policies of the six segments are the same as those described in Note 1 of the Notes to Consolidated Financial Statements.  No single customer represents more than 5% of consolidated revenues.  In
addition, all of the reportable segments' revenues are derived from sources within the U.S. and all reportable segments long-lived assets are located in the U.S.

The Gas Distribution segment is the Company's core business.  Its two regulated utilities purchase, distribute, sell and transport natural gas to approximately 1 million retail customers through a 6,000 mile distribution system serving the City of
Chicago and 54 communities in northeastern Illinois.  The Company also owns a storage facility in central Illinois and a pipeline which connects the facility and five major pipeline suppliers to Chicago.

The Power Generation segment is engaged in the development, construction, operation, and ownership of gas-fired electric generation facilities for sales to electric utilities and marketers.  The Company and Dominion Resources are equal investors in
Elwood Energy, which owns and operates a 600-megawatt peaking facility near Chicago, Illinois.

The Midstream Services segment performs wholesale activities that provide value to gas distribution utilities, marketers and pipelines.  The Company, through Peoples Gas, operates a natural gas hub.  It also owns and operates an NGL peaking
facility and is active in other asset-based wholesale activities.

The Retail Energy Services segment markets gas and electricity and provides energy management and other services to retail customers.  Peoples Gas home services activity is also part of this segment.

The Oil and Gas Production segment is active in the development and production of oil and gas reserves in selected basins in the United States.  The Company targets on-shore prospects with proved producing oil and gas reserves and the potential for
enhancement through drilling programs.

The Company is involved in other activities such as district heating and cooling and the development of natural gas fueling stations for natural gas vehicles.  These and other activities do not fall under the above segments and are reported in the
Other segment.

3: ENVIRONMENTAL MATTERS

A. Former Manufactured Gas Plant Operations

The Company's utility subsidiaries, their predecessors, and certain former affiliates operated facilities in the past at multiple sites for the purpose of manufacturing gas and storing manufactured gas (Manufactured Gas Sites).  In connection with
manufacturing and storing gas, various by-products and waste materials were produced, some of which might have been disposed of rather than sold.  Under certain laws and regulations relating to the protection of the environment, the subsidiaries might be
required to undertake remedial action with respect to some of these materials.  Two of the Manufactured Gas Sites are discussed in more detail below.  The subsidiaries, under the supervision of the Illinois Environmental Protection Agency (IEPA), are
conducting investigations of an additional 31 Manufactured Gas Sites.  These investigations may require the utility subsidiaries to perform additional investigation and remediation.  The investigations are in a preliminary stage and are expected to occur
over approximately three years.

In 1990, North Shore Gas entered into an Administrative Order on Consent (AOC) with the United States Environmental Protection Agency (EPA) and the IEPA to implement and conduct a remedial investigation/feasibility study (RI/FS) of a Manufactured
Gas Site located in Waukegan, Illinois, where manufactured gas and coking operations were formerly conducted (Waukegan Site).  The RI/FS was comprised of an investigation to determine the nature and extent of contamination at the Waukegan Site and a
feasibility study to develop and evaluate possible remedial actions.  North Shore Gas entered into the AOC after being notified by the EPA that North Shore Gas, General Motors Corporation (GMC), and Outboard Marine Corporation (OMC) were each a
potentially responsible party (PRP) under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA), with respect to the Waukegan Site.  A PRP is potentially liable for the cost of any investigative and remedial
work that the EPA determines is necessary.  Other parties identified as PRPs did not enter into the AOC.

Under the terms of the AOC, North Shore Gas is responsible for the cost of the RI/FS.  North Shore Gas believes, however, that it will recover a significant  portion of the costs of the RI/FS from other entities.  GMC has shared equally with North
Shore Gas in funding of the RI/FS cost, without prejudice to GMC's or North Shore Gas' right to seek a lesser cost responsibility at a later date.

On May 14, 1999, the EPA notified GMC, OMC, Elgin Joliet and Eastern Railway Company, and North Shore Gas that they were potentially liable with respect to the Waukegan Site and that the EPA intended to begin discussions regarding the design and
implementation of the remedial action selected for the Waukegan Site.

On September 30, 1999, the EPA issued the Record of Decision (ROD) selecting the remedial action for the Waukegan Site.  The remedy consists of on-site treatment of ground water, off-site treatment and disposal of soil containing polynuclear
aeromatic hydrocarbons or creosote, and on-site solidification/stabilization of arsenic contaminated soils.  The EPA has estimated the present worth of the remedy to be $26 million (representing the present worth of estimated capital costs and of
estimated operation and maintenance costs).

North Shore Gas and the other parties notified by the EPA have entered into discussions regarding implementation of the remedy and the allocation of costs associated with the investigation and remediation of the Waukegan Site.

The current owner of a site in Chicago, formerly called Pitney Court Station, filed suit against Peoples Gas in federal district court under CERCLA.  The suit seeks recovery of the past and future costs of investigating and remediating the site.
Peoples Gas is contesting this suit.

The utility subsidiaries are accruing and deferring the costs they incur in connection with all of the Manufactured Gas Sites, including related legal expenses, pending recovery through rates or from insurance carriers or other entities.  At
September 30, 1999, the total of the costs deferred (stated in current year dollars) for Peoples Gas was $23.5 million; for North Shore Gas the total was $19.7 million; and for the Company on a consolidated basis the total deferred was $43.2 million.
This amount includes management's best estimate of the costs of investigating and remediating the Manufactured Gas Sites.  The estimate is based upon a comprehensive review by management and its outside consultants of potential costs associated with
conducting investigative and remedial actions at the Manufactured Gas Sites as well as the likelihood of whether such actions will be necessary.  While each subsidiary intends to seek contribution from other entities for the costs incurred at the sites,
the full extent of such contributions cannot be determined at this time.

Peoples Gas and North Shore Gas have filed suit against a number of insurance carriers for the recovery of environmental costs relating to the utilities' former manufactured gas operations.  The suit asks the court to declare, among other things,
that the insurers are liable under policies in effect between 1937 and 1986 for costs incurred or to be incurred by the utilities in connection with five of their Manufactured Gas Sites in Chicago and Waukegan.  The utilities are also asking the court to
award damages stemming from the insurers' breach of their contractual obligation to defend and indemnify the utilities against these costs.  In November 1998, the utilities reached a settlement agreement with one of the insurance carriers.  The costs
deferred at September 30, 1999 have been reduced by the proceeds of the settlement.  At this time, management cannot determine the timing and extent of the subsidiaries' recovery of costs from the other insurance carriers.  Accordingly, the costs deferred
at September 30, 1999 have not been reduced to reflect recoveries from other insurance carriers.

Management believes that the costs incurred by Peoples Gas and by North Shore Gas for environmental activities relating to former manufactured gas operations are recoverable from insurance carriers or other entities or through rates for utility
service.  Accordingly, management believes that the costs incurred by the subsidiaries in connection with former manufactured gas operations will not have a material adverse effect on the financial position or results of operations of the utilities.
Peoples Gas and North Shore Gas are recovering the costs of environmental activities relating to the utilities' former manufactured gas operations, including carrying charges on the unrecovered balances, under rate mechanisms approved by the Commission.

B. Former Mineral Processing Site in Denver, Colorado

In 1994, North Shore Gas received a demand from the S.W. Shattuck Chemical Company, Inc. (Shattuck), a responsible party under CERCLA, for reimbursement, indemnification, and contribution for response costs incurred at a former mineral processing
site in Denver, Colorado.  Shattuck is a wholly owned subsidiary of Salomon, Inc. (Salomon).  The demand alleges that North Shore Gas is a successor to the liability of a former entity that was allegedly responsible during the period 1934-1941 for the
disposal of mineral processing wastes containing radium and other hazardous substances at the site.  In 1992, the EPA issued the Record of Decision (ROD) for the Denver site.  The remedy selected in the ROD consisted of the on-site stabilization,
solidification and capping of soils containing radioactive wastes.  In 1997, the remedial action was completed.  The cost of the remedy at the site has been estimated by Shattuck to be approximately $31 million.  Salomon has provided financial assurance
for the performance of the remediation of the site.

North Shore Gas filed a declaratory judgment action against Salomon in the District Court for the Northern District of Illinois.  The suit asked the court to declare that North Shore Gas is not liable for response costs at the Denver site.  Salomon
filed a counterclaim for costs incurred by Salomon and Shattuck with respect to the site.  In 1997, the District Court granted North Shore Gas' motion for summary judgment, declaring that North Shore Gas is not liable for any response costs in connection
with the Denver site.

On August 5, 1998, the U.S. Court of Appeals, Seventh Circuit, reversed the District Court's decision and remanded the case for determination of what liability, if any, the former entity has and therefore North Shore Gas has for activities at the
site.

North Shore Gas does not believe that it has liability for the response costs, but cannot determine the matter with certainty.  At this time, North Shore Gas cannot reasonably estimate what range of loss, if any, may occur.  In the event that North
Shore Gas incurred liability, it would pursue reimbursement from insurance carriers, other responsible parties, if any, and through its rates for utility service.

4: COVENANTS REGARDING RETAINED EARNINGS

North Shore Gas' indenture relating to its first mortgage bonds contains provisions and covenants restricting the payment of cash dividends and the purchase or redemption of capital stock.  At September 30, 1999, such restrictions amounted to $11.6
million out of North Shore Gas' total retained earnings of $72.1 million.

5: LONG-TERM LEASE

Peoples Gas has entered into a long-term operating lease for its headquarters office which expires in 2008.

The rental obligation consists of a base rent of $2.3 million plus operating expenses and taxes.  The base rent escalates by 2 percent each year through 2003.  Base rent in 2004 is approximately $3.6 million with annual increases of 2 percent each
year through 2008.

Rental expenses for the headquarters office were $6.6 million, $6.5 million, and $6.4 million for fiscal years 1999, 1998 and 1997, respectively.

6: EARNINGS PER SHARE

The table below shows average and diluted shares for computing the Company's per share amounts.  The dilution is attributable to stock options outstanding under the Long-Term Incentive Compensation Plan.



|                   | Average Common Stock 
|------------------ | ---------------------
|                   | Shares (in thousands)
|Fiscal Years       | 1999                 
|As reported shares | 35,477               
|Effects of options | 13                   
|Diluted shares     | 35,490               

Options for which the average stock price is lower than the grant price are considered antidilutive and, therefore, are not included in the calculation of diluted earnings per share.

7: COMPREHENSIVE INCOME

SFAS No. 130, "Reporting Comprehensive Income," was adopted in fiscal 1999.  This statement requires the reporting of comprehensive income in addition to net income.  Comprehensive income is the total of net income and all other nonowner
changes in equity (other comprehensive income).  Comprehensive income includes net income plus the effect of the additional pension liability not yet recognized as net periodic pension cost.  The Company has reported accumulated other comprehensive income
in its Consolidated Statement of Stockholders' Equity.

Comprehensive income for the Company for fiscal years 1999, 1998 and 1997 is as follows:

In January 1999, Peoples Gas eliminated a $13.0 million decommissioning reserve associated with the 1995 retirement of its synthetic natural gas plant.  This elimination resulted in the recognition of $13.0 million in other income.  Management
determined that it did not expect the plant's decommissioning costs to exceed amounts incurred to date through January 1999.

9: RETIREMENT AND POSTRETIREMENT BENEFITS

The Company and its subsidiaries adopted SFAS No. 132, "Employers' Disclosures about Pensions and Other Postretirement Benefits."  This statement requires disclosure of new accounting information on changes in plan benefit obligations and fair
values of plan assets.  The adoption of this standard did not affect results of operations or financial position, but it did affect the disclosure of pension and postretirement benefits information.

The Company and its subsidiaries participate in two defined benefit pension plans covering substantially all employees.  These plans provide pension benefits that generally are based on an employee's length of service, compensation during the five
years preceding retirement, and social security benefits.  System companies make contributions to the plans based upon actuarial determinations and in consideration of tax regulations and funding requirements under federal law.  The Company and its
subsidiaries also has non-qualified pension plans that provide certain employees with pension benefits in excess of qualified plan limits imposed by federal tax law.

In addition, the Company and its subsidiaries provide certain health care and life insurance benefits for retired employees.  Substantially all employees may become eligible for such benefit coverage if they reach retirement age while working for
the Company.  The plans are funded based upon actuarial determinations and in consideration of tax regulations.  The Company accrues the expected costs of such benefits during the employees' years of service.

Reconciliations of the beginning and ending balances of the projected pension benefit obligation and the accumulated postretirement benefit obligation, reconciliations of the beginning and ending balances of the plan assets, and the funded status
of these plans for years 1999 and 1998 are as follows:

For measurement purposes, a health care cost trend rate of 7.1% was assumed for fiscal 1999, and that rate thereafter will decline gradually to 4.75% in 2001 and subsequent years.  The health care cost trend rate assumption has a significant effect
on the amounts reported.  Increasing the assumed health care cost trend rate by one percentage point for each future year would have increased the accumulated postretirement benefit obligation at September 30, 1999, by $8.7 million and the aggregate of
service and interest cost components of the net periodic postretirement benefit cost by $1.3 million annually.  Decreasing the assumed health care cost trend rate by one percentage point for each future year would have decreased the accumulated
postretirement benefit obligation at September 30, 1999, by $7.5 million and the aggregate of service and interest cost components of the net periodic postretirement benefit cost by $1.1 million annually.

At September 30, 1999, Peoples Energy had combined lines of credit totaling $170.0 million.  Agreements covering $150.0 million of the total at September 30, 1999, will expire on December 12, 1999; the agreement covering the remaining $20.0 million
will expire on July 30, 2000.  Such lines of credit cover the projected short-term credit needs of the Company.  Payment for the lines of credit is by fee.

At September 30, 1999 and 1998, the utility subsidiaries had combined lines of credit totaling $119.0 million and $129.4 million, respectively.  Of this total, North Shore Gas could borrow up to $30.0 million.  Agreements covering $92.0 million of
the total at September 30, 1999, will expire on August 28, 2000; the agreement covering the remaining $27.0 million will expire on January 31, 2001.  Such lines of credit cover projected short-term credit needs of the subsidiaries and support the
long-term debt treatment of Peoples Gas' adjustable-rate mortgage bonds.  (See Note 14A.)  Payment for the lines of credit is by fee.

14: LONG-TERM DEBT

A. Interest-Rate Adjustments

The rate of interest on the City of Chicago 1993 Series B Bonds, which are secured by Peoples Gas' Adjustable-Rate First and Refunding Mortgage Bonds, Series EE, is subject to adjustment annually on December 1.  Owners of the Series B Bonds have
the right to tender such bonds at par during a limited period prior to that date.  Peoples Gas is obligated to purchase any such bonds tendered if they cannot be remarketed.  All Series B Bonds that were tendered prior to December 1, 1998, have been
remarketed.  The interest rate on such bonds is 3.20% for the period December 1, 1998, through November 30, 1999.

Peoples Gas classifies these adjustable-rate bonds as long-term liabilities since it would refinance them on a long-term basis if they could not be remarketed.  In order to ensure its ability to do so, Peoples Gas has established a $27.0 million
line of credit with The Northern Trust Company which  extends to January 31, 2001. (See Note 13.)

B. Sinking Fund Requirements and Maturities of Subsidiaries

At September 30, 1999, long-term debt sinking fund requirements and maturities for the next five years are:

On October 1, 1998, Peoples Gas redeemed, from general corporate funds, $10.4 million aggregate principal amount of the City of Joliet 1984 Series C Bonds, which were secured by Peoples Gas' Adjustable-Rate First and Refunding Mortgage Bonds,
Series W.  The rate of interest on the City of Joliet 1984 Series C Bonds, which were secured by Peoples Gas' Adjustable-Rate First and Refunding Mortgage Bonds, Series W, was subject to adjustment annually on October 1.  Owners of the Series C Bonds had
the rig
such bonds at par during a limited period prior to that date.  Peoples Gas was obligated to purchase any such bonds tendered if they could not be remarketed.  The interest rate for the Series C Bonds for fiscal 1998 was 3.875%.  All Series C Bonds were
redeemed on October 1, 1998.

On December 18, 1998, the Illinois Development Finance Authority issued $30,035,000 aggregate principal amount of 5.00% Gas Supply Revenue Bonds, Series 1998, which were collateralized by an equal amount of North Shore Gas' 30-year First Mortgage
Bonds, Series M.  The net proceeds were deposited with a trustee to be used for the redemption of long-term debt, the payment of issuance costs, and for the payment of certain construction expenditures.

C. Fair Value of Financial Instruments

At September 30, 1999, the carrying amount of the Company's long-term debt of $521.7 million had an estimated fair value of $523.1 million.  At September 30, 1998, the carrying amount of the Company's long-term debt of $527.0 million had an
estimated fair value of $561.7 million.  The estimated fair value of the Company's long-term debt is based on yields for issues with similar terms and remaining maturities.  Since Peoples Gas and North Shore Gas are subject to regulation, any gains or
losses related to the difference between the carrying amount and the fair value of financial instruments may not be realized by the Company's shareholders.

The carrying amount of all other financial instruments approximates fair value.

At September 30, 1999, the carrying amount of Peoples Gas' long-term debt of $452.0 million had an estimated fair value of $457.0 million.  At September 30, 1998, the carrying amount of Peoples Gas' long-term debt of $462.4 million had an estimated
fair value of $494.9 million.  The estimated fair value of Peoples Gas' long-term debt is based on yields for issues with similar terms and remaining maturities.  Since Peoples Gas is subject to regulation, any gains or losses related to the difference
between the carrying amount and the fair value of financial instruments may not be realized by Peoples Gas' shareholder.  The carrying amount of all other financial instruments approximates fair value.

At September 30, 1999, the carrying amount of North Shore Gas' long-term debt of $69.7 million had an estimated fair value of $66.1 million.  At September 30, 1998, the carrying amount of North Shore Gas' long-term debt of $64.6 million had an
estimated fair value of $66.8 million.  The estimated fair value of North Shore Gas' long-term debt is based on quoted market prices or yields for issues with similar terms and remaining maturities.  Since North Shore Gas is subject to regulation, any
gains or losses related to the difference between the carrying amount and the fair value of financial instruments may not be realized by the North Shore Gas' shareholder.  The carrying amount of all other financial instruments approximates fair value.

15: PREFERRED STOCK

The Company has five million shares of Preferred Stock, no par value, authorized for issuance, of which none was issued and outstanding at September 30, 1999.

Restricted stock awards granted to officers of the Company during the last three fiscal years are as follows: 1999, 17,750 shares; 1998, 15,800 shares; and 1997, 15,100 shares.  Forfeitures during the same period were as follows: 1999, 0 shares;
1998, 940 shares; and 1997, 2,025 shares.  At September 30, 1999, there were 262,535 shares available for future grant under options or restricted stock awards.  At September 30, 1999, there were 404,975 SARs available for future grant.

The grant of a restricted stock award entitles the recipient to vote the shares of company common stock covered by such award and to receive dividends thereon.  Restricted stock awards are valued at the closing market price of the stock as of the
date of the grant.  The recipient may not transfer or otherwise dispose of such shares until the restrictions thereon lapse.  Restricted stock awards granted to date vest in equal annual increments over a five-year period from the date of grant.  If a
recipient's employment with the Company terminates, other than by reason of death, disability, or retirement after attaining age 65, the recipient forfeits all rights to the unvested portion of the restricted stock award.  The Compensation-Nominating
Committee of the Company's Board of Directors (and with respect to the Chief Executive Officer, the Compensation-Nominating Committee, subject to the approval of the non-employee directors) may, in its sole discretion, accelerate the vesting of any
restricted stock awards granted under the LTIC.

The grant of an option enables the recipient to purchase company common stock at a purchase price equal to the fair market value of the shares on the date the option was granted.  The grant of an SAR enables the recipient to receive, for each SAR
granted, cash in an amount equal to the excess of the fair market value of one share of company common stock on the date the SAR is exercised over the fair market value of one share on the date the SAR was granted.  Before an option or SAR may be
exercised, the recipient must complete 12 months of continuous employment subsequent to the grant of the option or SAR.  Options and SARs may be exercised within 10 years from the date of grant, subject to earlier termination in case of death, retirement,
or termination of employment for other reasons.

The Company grants stock options, SARs, and restricted stock awards under its LTIC.  The Company also offers employees periodic opportunities to purchase shares of its common stock at a discount from the then current market price under its Employee
Stock Purchase Plan (ESPP).  The Company applies Accounting Principles Board (APB) Opinion No. 25 and related Interpretations in accounting for these plans.

The Company may sell up to 952,306 shares of common stock to its employees under the ESPP.  Under the terms of this plan, all employees with a minimum of one year of service are eligible to purchase shares at 90% of the stock's market price at the
date of purchase.  The Company sold 13,961 shares, 15,381 shares and 16,349 shares to employees in 1999, 1998 and 1997, respectively.

Under APB Opinion No. 25, no compensation cost has been recognized for nonqualified stock options and shares issued under the ESPP.  The compensation cost that has been charged against net income for restricted stock awards was $618,000, $345,000
and $452,000 for the years ended September 30, 1999, 1998 and 1997, respectively.  Had compensation cost for stock options, SARs and shares issued under the ESPP been determined consistent with SFAS No. 123, "Accounting for Stock-Based
Compensation," the Company's net income and earnings per share would have been reduced to the following pro forma amounts:

|Pro forma            | 2.58                                 

Since the SFAS No. 123 method of accounting has not been applied to options granted prior to October 1, 1995, the resulting pro forma compensation costs may not be representative of those to be expected in future years.

The fair value of each option grant used to determine pro forma net income is estimated as of the date of grant using a variation of the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants in the years
ended September 30, 1999, 1998, and 1997 respectively: expected volatility of 17.48, 18.39 and 15.78 percent; dividend yield of 5.6, 5.3, and 5.0 percent; risk-free interest rates of 4.29, 5.78 and 6.03 percent, and expected lives of three and one-half
years for 1999 and 1998, and two years for 1997.  The weighted-average fair value of options, SARs and Restricted Stock Awards granted was $3.35, $4.61, and $2.90 for the years ended September 30, 1999, 1998, and 1997, respectively.

17: QUARTERLY FINANCIAL DATA (UNAUDITED)

All quarterly results were impacted by weather.  The second quarter of fiscal 1999 also reflected the elimination of the decommissioning reserve associated with the 1995 retirement of Peoples Gas' synthetic natural gas plant.  Fourth quarter
results were positively impacted by income from the Company's investment in the Elwood facility.

Quarterly financial data for Peoples Energy was as follows:

18: EVENTS (UNAUDITED) SUBSEQUENT TO THE AUDITORS' REPORT DATED OCTOBER 29, 1999

On November 16, 1999, the EPA announced that it was reopening the ROD for the Denver site.  The EPA's announcement followed a six-month scientific/technical review by the agency of the remedy's effectiveness.  The EPA stated that it would issue a
proposed plan for public comment in December 1999 that would recommend removal of the wastes to an off-site disposal facility as the preferred alternative for further action at the site.  According to the agency, the preferred alternative would have an
estimated additional cost of $15 million to $25 million.  The EPA said that it would make a final decision on additional measures to be taken at the site by March 2000.  (See Note 3B of the Notes to Consolidated Financial Statements.)

(1)  Restricted stock awards are valued at the closing market price as of the date of grant.  The total number of restricted shares held by the named executive officers and the aggregate market value of such shares at September 30, 
1999 were as follows: Mr. Terry, 15,480 shares, valued at $544,703; Mr. Patrick, 5,720 shares, valued at $201,273; Mr. Hinchliff, 4,830 shares, valued at $169,956; Mr. Field, 2,155 shares, valued at $75,829; and Mr. Luebbers, 1,275 shares, valued at
$44,864.  Dividends are paid on the restricted shares at the same time and at the same rate as dividends paid to all shareholders of common stock.  Aggregate market value is based on a per share price of $35.1875, the closing price of Peoples Energy's
stock on the New York Stock Exchange on September 30, 1999.

(2)  Restricted stock awards granted to date vest in equal annual increments over a five-year period.  If a recipient's employment with Peoples Gas or North Shore Gas terminates, other than by reason of death, disability, or retirement after
attaining age 65, the recipient forfeits all rights to the unvested portion of the restricted stock award.  In addition, the Compensation-Nominating Committee (and with respect to the CEO, the Compensation-Nominating Committee, subject to the approval of
the non-employee directors) may, in its sole discretion, accelerate the vesting of any restricted stock awards granted under the Long-Term Incentive Compensation Plan.  Total restricted stock awarded to the named individuals for 1997 constitutes 7,575
shares, of which 1,515 shares vested in 1998; 1,515 shares vested in 1999; 1,515 shares will vest in 2000; 1,515 shares will vest in 2001; and the remaining 1,515 shares will vest in 2002. Total restricted stock awarded to the named individuals for 1998
constitutes 8,800 shares, of which 1,760 shares vested in 1999; 1,760 shares will vest in 2000; 1,760 shares will vest in 2001; 1,760 shares will vest in 2002; and the remaining 1,760 shares will vest in 2003. Total restricted stock awarded to the named
individuals for 1999 constitutes 12,850 shares, of which 2,570 shares will vest in 2000; 2,570 shares will vest in 2001; 2,570 shares will vest in 2002; 2,570 shares will vest in 2003; and the remaining 2,570 shares will vest in 2004.

Peoples Gas and North Shore Gas contributions to the Capital Accumulation Plan accounts of the named executive officers during the above fiscal years.  Employee contributions under the plan are subject to a maximum limitation under the
Internal Revenue Code of 1986, as amended.  Peoples Gas and North Shore Gas pays an employee who is subject to this limitation an additional 60 cents, effective October 1, 1998, for each dollar that the employee is prevented from contributing solely by
reason of such limitation.  The amounts shown in the table above reflect, if applicable, this additional payment by Peoples Gas and North Shore Gas.

(1)  The grant of an Option enables the recipient to purchase Peoples Energy common stock at a purchase price equal to the fair market value of the shares on the date the Option is granted.  The grant of an SAR enables the recipient to
receive, for each SAR granted, cash in an amount equal to the excess of the fair market value of one share of Peoples Energy common stock on the date the SAR is exercised over the fair market value of such common stock on the date the SAR was granted.
Options or SARs that expire unexercised become available for future grants.  Before an Option or SAR may be exercised, the recipient must complete 12 months of continuous employment subsequent to the grant of the Option or SAR.  Options and SARs may be
exercised within 10 years from the date of grant, subject to earlier termination in case of death, retirement, or termination of employment.

(2)  Based on 107,575 Options and 107,575 SARs granted to all employees under Peoples Energy's Long-Term Incentive Compensation Plan during fiscal 1999.

(3)  The Present Value of each option grant used to determine pro forma net income is estimated as of the date of grant using a variation of the Black-Scholes option-pricing model with the following weighted-average assumptions: expected
volatility of 17.48 percent, dividend yield of 5.6 percent, risk-free interest rate of 4.29 percent, and expected life of three and one-half years.  The weighted-average fair value of options granted was $3.35 for the year ended September 30, 1999.

The above table illustrates various annual straight-life benefits at normal retirement (age 65) for the indicated levels of average annual compensation and various periods of service, assuming no future changes in the Company's pension benefits.
The compensation used in the computation of annual retirement benefits is substantially equivalent to the salary and bonus reported in the Summary Compensation Table.  The benefit amounts shown reflect reduction for applicable Social Security benefits.

Average annual compensation is the average 12-month compensation for the highest 60 consecutive months of the last 120 months of service prior to retirement.  Compensation is total salary paid to an employee by the Company and/or its affiliates,
including bonuses under Peoples Energy's Short-Term Incentive Compensation Plan, pre-tax contributions under Peoples Energy's Capital Accumulation Plan, pre-tax contributions under Peoples Energy's Health and Dependent Care Spending Accounts Plan, and
pre-tax contributions for life and health care insurance, but excluding moving allowances, exercise of stock options and SARs, and other compensation that has been deferred.

At September 30, 1999, the credited years of retirement benefit service for the individuals listed in the Summary Compensation Table were as follows: Mr. Terry, 35 years; Mr. Patrick, 23 years; Mr. Hinchliff, 27 years; Mr. Field, 28 years; and
Mr. Luebbers, 30 years.  The benefits shown in the foregoing table are subject to maximum limitations under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended.  Should these benefits at the
time of retirement exceed the then-permissible limits of the applicable Act, the excess would be paid by the Company as supplemental pensions pursuant to Peoples Energy's Supplemental Retirement Benefit Plan.  The benefits shown give effect to these
supplemental pension benefits.



SEVERANCE AGREEMENTS

The Company has entered into separate severance agreements with certain key executives, including each of the executives named in the Summary Compensation Table.  The intent of the severance agreements is to assure the continuity of the Company's
administration and operations in the event of a Change in Control of the Company (as described below).  The severance agreements were developed in accordance with the advice of outside consultants.

The term of each severance agreement is for the longer of 36 months after the date in which a Change in Control of the Company occurs or 24 months after the completion of the transaction approved by shareholders described in (iii) below of the
description of a Change in Control.  A  Change in Control is defined as occurring when (i) the Company receives a report on Schedule 13D filed with the Securities and Exchange Commission pursuant to Section 13(d) of the Securities Exchange Act of 1934, as
amended, disclosing that any person, group, corporation, or other entity is the beneficial owner, directly or indirectly, of 20% or more of the common stock of the Company; (ii) any person, group, corporation, or other entity (except the Company or a
wholly-owned subsidiary), after purchasing common stock of the Company in a tender offer or exchange offer, becomes the beneficial owner, directly or indirectly, of 20% or more of such common stock; (iii) the shareholders of the Company approve (a) any
consolidation or merger of the Company in which the Company is not the continuing  or surviving corporation, other than a consolidation or merger in which holders of the Company's common stock prior to the consolidation or merger have substantially the
same proportionate ownership of common stock of the surviving corporation immediately after the consolidation or merger as immediately before; (b) any consolidation or merger in which the Company is the continuing or surviving corporation, but in which
the common shareholders of the Company immediately prior to the consolidation or merger do not hold at least 90% of the outstanding common stock of the Company; (c) any sale, lease, exchange or other transfer of all or substantially all of the assets of
the Company, except where the Company owns all of the outstanding stock of the transferee entity or the Company's common shareholders immediately prior to such transaction own at least 90% of the transferee entity or group of transferee entities
immediately after such transaction; or (d) any consolidation or merger of the Company where, after the consolidation or merger, one entity or group of entities owns 100% of the shares of the Company, except where the Company's common shareholders
immediately prior to such merger or consolation own at least 90% of the outstanding stock of such entity or group of entities immediately after such consolidation or merger; or (iv) a change in the majority of the members of the Company's Board of
Directors within a 24-month period, unless approved by two-thirds of the directors then still in office who were in office at the beginning of the 24-month period.

Each severance agreement provides for payment of severance benefits to the executive in the event that, during the term of the severance agreement, (i) the executive's employment is terminated by the Company, Peoples Gas or North Shore Gas except
for "cause" as defined therein; or (ii) the executive's employment is terminated due to a constructive discharge, which includes (a) a material change in the executive's responsibilities, which change would cause the executive's position with the Company
to become of less dignity, responsibility, prestige or scope; (b) reduction, which is more than de minimis, in total compensation; (c) assignment without the executive's consent to a location more than 50 miles from the current place of employment; or (d)
liquidation, dissolution, consolidation,  merger, or sale of all or substantially all of the assets of the Company, Peoples Gas or North Shore Gas unless the successor corporation has a net worth at least equal to that of the Company, Peoples Gas or North
Shore Gas and expressly assumes the obligations of the Company under the executive's severance agreement.

The principal severance benefits payable under each severance agreement consist of the following:  (i) the executive's base salary and accrued benefits through the date of termination, including a pro rata portion of  awards under the Company's
STIC Plan; (ii) three times the sum of the individual's base salary, the average of the STIC Plan awards for the prior three years and the value of the LTIC Plan awards in the prior calendar year; and (iii) the present value of the executive's accrued
benefits under the Company's Supplemental Retirement Benefits Plan (SRBP) that would be payable upon retirement at normal retirement age, computed as if the executive had completed three years of additional service.  In addition, the executive will be
entitled to continuation of life insurance and medical benefits for the longer of (a) a period of three years after termination or (b) a period commencing after termination and ending when the executive may receive pension benefits without actuarial
reduction, provided that the Company's obligation for such benefits under the severance agreement shall cease upon the executive's employment with another employer that provides life insurance and medical benefits.  Each severance agreement also provides
that the executive's Options and SARs shall become exercisable upon a Change in Control and that all Options and SARs shall remain exercisable for the shorter of (a) three years after termination or (b) the term of such Options and SARs.  Any restricted
stock previously awarded to the executive under the LTIC Plan would vest upon a Change in Control if such vesting does not occur due to a Change in Control under the terms of the LTIC Plan.  The Company is also obligated under each severance agreement to
pay an additional amount to the executive sufficient on an after-tax basis to satisfy any excise tax liability imposed by Section 4999 of the Internal Revenue Code of 1986, as amended.  The benefits received by the executive under each agreement are in
lieu of benefits under the Company's termination allowance plan and the executive's benefits under the SRBP.  Each executive would be required to waive certain claims prior to receiving any severance benefits.
