Part I - Financial Information

Item I. Financial Statements

The condensed unaudited financial statements of Peoples Energy Corporation (the Company) have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).

This Quarterly Report on Form 10-Q is a combined report of the Company, The Peoples Gas Light and Coke Company (Peoples Gas) and North Shore Gas Company (North Shore Gas).

Certain footnote disclosures and other information, normally included in financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted from these interim financial statements, pursuant to
SEC rules and regulations.  Therefore, the statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company's, Peoples Gas' and North Shore Gas' Annual Report on Form 10-K, as amended, for the
fiscal year ended September 30, 2000.  Certain items previously reported for the prior periods have been reclassified to conform with the presentation in the current period.

The business of the Company's utility subsidiaries (Peoples Gas and North Shore Gas) is influenced by seasonal weather conditions because a large element of the utilities' customer load consists of gas used for space heating.  Weather-related
deliveries can, therefore, have a significant positive or negative impact on net income.  Swings in natural gas prices can also impact revenue sensitive items such as customer accounts receivable balances and reserves for uncollectible accounts.  The
quarterly results of operations and balances should not be considered indicative of the year as a whole.

The information furnished reflects, in the opinion of management, all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of the results of operations for the interim periods presented.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)



1. SIGNIFICANT ACCOUNTING POLICIES

Recovery of Gas Costs

Under the tariffs of Peoples Gas and North Shore Gas, all reasonably incurred gas costs are recoverable from customers through a charge for gas (the "Gas Charge").  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 Illinois Commerce Commission (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 the fiscal year 2000 are currently pending before the Commission.

Derivative Instruments and Hedging Activities

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities", amended by SFAS No. 137 and SFAS No. 138, (collectively "SFAS
No. 133").  SFAS No. 133 establishes accounting and reporting standards requiring that every derivative instrument (including certain derivative instruments embedded in other contracts) be recorded on the balance sheet as either an asset or liability
measured at its fair value.  SFAS No. 133 requires that changes in the derivative's fair value be recognized currently in earnings unless specific hedge accounting criteria are met.  Special accounting for qualifying hedges allows a derivative's gains and
losses to offset related results on the hedged item on the income statement, and requires that a company must formally document, designate, and assess the effectiveness of transactions that receive hedge accounting.

The Company hedges forecasted cash flows related to commodities and certain interest rate risks.  The impact on the financial statements of adopting SFAS No. 133 as of October 1, 2000, was to reduce earnings by $34,000, net of tax, reduce
accumulated other comprehensive income (AOCI) by $23.6 million, net of tax, record a liability of $40.0 million, record an increase in investment in equity investees of $900,000 and record deferred taxes of $15.5 million.  Based on October 1 values, the
Company estimates that in 2001, it will reclassify from AOCI to the Consolidated Statement of Income deferred losses totaling $17.9 million, net of tax, which are expected to offset gains on the hedged transactions.

The Company has hedged various anticipated cash flow transactions through 2006.  During the three and six months ended March 31, 2001, the Company reclassified $5.4 million and $9.9 million net of tax, respectively, of deferred losses from AOCI to
the Consolidated Statement of Income to offset gains realized by the hedged transactions.  In the following 12 months, $12.9 million of deferred losses will be reclassified from AOCI into earnings.  The deferred loss is reported in the same income
statement line as the gain or loss from the hedged transaction.  As of March 31, 2001, the Company has $49.8 million of derivative liabilities and has cumulative deferred losses in AOCI of $30.0 million, net of tax.  As of the balance sheet date, Peoples
Gas and North Shore Gas have no derivative instruments.

In the three-month period, the cash flow hedges by the Elwood joint venture were liquidated as hedges resulting in recognizing gains of $4.0 million ($2.4 million, net of taxes).  The power sales contracts were renegotiated to essentially
eliminate the fuel price risk that the hedges were designed to protect.

3.  ENVIRONMENTAL MATTERS

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 $26.5 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.

On December 22, 2000, OMC filed a petition in federal bankruptcy court seeking protection under Chapter 11 of the United States Bankruptcy Code.

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 March
31, 2001, the total of the costs deferred (stated in current year dollars) for Peoples Gas was $34.8 million; for North Shore Gas the total was $20.2 million; and for the Company on a consolidated basis the total deferred was $55.0 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 March 31, 2001 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
March 31, 2001 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.

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 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 $31.0 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.

In August 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.

In November 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.  In June 2000, the EPA amended the ROD to
require removal of the radioactive wastes from the site to a licensed off-site disposal facility.  The EPA estimates that this action will cost  an additional $21.5 million (representing the present worth of estimated capital costs and estimated operation
and maintenance costs).

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.

Peoples Gas and North Shore Gas are inspecting for mercury contamination in certain of their customers' premises where gas pressure regulators, manometers and other equipment containing mercury may have been used.  The utilities have identified
approximately 93,000 locations where gas pressure regulators, manometers and other equipment containing mercury may have been used.  Virtually all of the gas pressure regulators containing mercury that were used for residences and other small volume
customers were removed by the utilities in the 1960's, 1970's and 1980's.  The utilities' inspection program includes both a visual check for mercury and a verification with mercury detection equipment.



As of March 31, 2001, Peoples Gas has visually inspected approximately 31,119 premises (including 29,523 small volume customers, primarily residences) and small amounts of mercury were found in 34 of these locations (of which 16 were residences).
North Shore Gas has visually inspected approximately 37,598 premises (including 37,219 small volume customers, primarily residences) and small amounts of mercury were found in 26 of these locations (of which 25 were residences).

In each case where mercury contamination is found, Peoples Gas or North Shore Gas will perform appropriate remediation at the premises to eliminate contamination.  Based on information available at March 31, 2001, it does not appear that mercury
contamination discovered by the utilities has had or will have a significant harmful effect on the public.

The Company has incurred and expects to continue to incur costs for inspection and remediation and other costs related to the program.  The Company charged $16.1 million (of which Peoples Gas and North Shore Gas charged $8.0 million and $8.1
million, respectively) to operating expense in the fourth quarter of fiscal year 2000, including the accrual recorded in accounts payable of $15.0 million (of which Peoples Gas and North Shore Gas recorded $7.0 million and $8.0 million, respectively) to
account for the estimated remaining costs related to the program.  Actual costs incurred as of March 31, 2001 for Peoples Gas and North Shore Gas were $2.5 million and $2.8 million, respectively.  As of March 31, 2001 neither the Company nor the utilities
have been named as a defendant in any lawsuit.  The Company intends to vigorously pursue the recovery of mercury-related costs from insurance.



4.  COMPREHENSIVE INCOME

SFAS No. 130, "Reporting Comprehensive Income," 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, the effect of the additional pension liability not yet recognized as net periodic pension cost, and  unrealized gains and losses from derivative instruments that qualify as cash flow hedges per SFAS No.
133. The Company and Peoples Gas have reported accumulated other comprehensive income in their respective Consolidated Balance Sheets

Comprehensive income for the Company for the three and six months ended March 31, 2001 and 2000 is as follows:

Item 2.  Management's Discussion and Analysis of Results of Operations and Financial Condition

RESULTS OF OPERATIONS



The following should be read in conjunction with the Management's Discussion and Analysis of Results of Operations and Financial Condition (MD&A) of Peoples Energy Corporation, The Peoples Gas Light and Coke Company and North Shore Gas Company
2000 Annual Report on Form 10-K, as amended.

Summary

Net income for the three months ended March 31, 2001 increased to $62.5 million, compared to $57.4 million in the year ago period.  The $5.1 million increase ($9.4 million before taxes) was mainly the result of increased gas delivery volumes
due to weather that was 19 percent colder than the same period last year and increased earnings from diversified businesses. In addition to the positive impact from weather ($11.7 million), gas distribution segment income also benefited from lower
depreciation expense ($3.6 million) and the effects of pension benefit accounting ($7.6 million).  Earnings for the quarter were negatively impacted by an increase in the utilities provision for uncollectible accounts ($8.3 million) due to higher revenues
resulting from unusually cold weather and significantly higher natural gas prices.  (See Liquidity and Capital Resources - "Balance Sheet Variations" for discussion of increased accounts receivables due to increased gas prices and related impact on bad
debt reserves.)  Increased earnings from the power generation ($5.0 million), retail energy services ($2.3 million) and oil and gas production ($1.1 million) segments were partially offset by a decrease in earnings from the midstream services segment
($798,000).  The current period also included higher financing costs due to increased short-term borrowings by the utilities ($1.9 million) and interest on the Company's long-term notes issued in July 2000 and January 2001 ($6.2 million).

Net income for the six months ended March 31, 2001 increased to $98.8 million, compared to $87.0 million in the year ago period.  The $11.8 million increase ($19.5 million before taxes) was mainly a result of increased gas delivery volumes due to
weather that was 23 percent colder than the same period last year.  The gas distribution segment earnings benefited from the effects of pension benefit accounting ($11.6 million) and lower depreciation expense ($6.8 million).  These effects were offset,
in part, by an increase in the utilities provision for uncollectible accounts ($12.9 million) due to unseasonably cold weather and significantly higher natural  gas prices.  All diversified business segments produced earnings growth for the six-month
period.

A summary of variations affecting income between years is presented below, followed by explanations of significant differences by segment.

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 one 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 six major interstate pipelines 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.  In general, the unit cost of gas does not have a significant direct effect on operating income because of the utilities' tariffs that provide for dollar-for-dollar recovery of gas costs.  (See Note 1 of the Notes to Consolidated
Financial Statements.)  However, unusually higher natural gas costs that continue for an extended period of time could adversely affect the accrual for the provision for uncollectible accounts and interest expense.

Operating revenues for the Company increased $467.4 million to $902.0 million and $720.7 million to $1.49 billion for the three- and six-month periods, respectively.  The increases were due mainly to higher unit prices of gas ($424.5 million and
$607.0 million) and to weather that was 19 percent and 23 percent colder than the prior periods.  Increases in revenues are not necessarily indicative of operating results.  Operating income increased $2.7 million to $101.6 million and $23.7 million to
$180.0 million for the three- and six-month periods, respectively.  The increase was due mainly to the colder weather ($11.7 million and $27.8 million), pension accounting benefits ($7.6 million and $ 11.6 million), lower depreciation expense ($3.6
million and $ 6.8 million) and the reduced use of external labor ($1.7 million and $1.6 million). However, operating income was negatively affected by reduced normalized gas deliveries primarily from customer conservation resulting from higher natural gas
costs ($13.7 million and $14.5 million) and an increase in the provision for uncollectible accounts ($8.3 million and $ 12.9 million).  (See Liquidity and Capital Resources - "Balance Sheet Variations" for discussion of increased accounts receivables due
to increased gas prices and related impact on bad debt reserves.)







The Company's objectives for the Gas Distribution segment center on continuous improvement, technological advancements, safety and customer service. Operating revenues are expected to increase from the prior year due to colder weather and
increased gas prices.  Segment operating income for fiscal 2001 is expected to improve due to the colder weather, reduced operation and maintenance expense and lower depreciation expense, partially offset by reduced normalized consumption and increased
uncollectible expense due to colder weather and higher gas prices.

Power Generation Segment

The Company is engaged in the development, construction, operation and ownership of natural gas-fired electric generation facilities for sales to electric utilities and marketers.  The Company and Dominion Energy, Inc. are equal investors in
Elwood Energy, which owns and operates a 600-megawatt peaking facility near Chicago, Illinois.  Expansion of the Elwood facility has begun which will increase the generating capacity to 1,350 megawatts upon completion of construction in time to meet power
demand for summer 2001.

Revenue recognition for these peaking facilities is based on contract provisions which assign higher value to summer capacity.  Additionally, current quarter results reflect a restructuring of existing contracts, therefore quarterly results are
not indicative of total year results.

Operating income and equity investment income for the three- and six-month periods was $5.6 million and $6.0 million, respectively, representing increases of $5.0 million and $2.1 million from the year ago periods.  These results are primarily due
to a gain on the liquidation of financial hedges associated with Elwood's gas supply requirements ($4.0 million and $4.0 million) and increased capacity payments during the second quarter ($2.3 million).  These increases were offset, in part, by higher
gas costs during both periods ($700,000 and $1.7 million).  Effective March 1, 2001, the power sales contracts on the Phase I Elwood units were restructured to essentially eliminate Elwood's fuel price risk.

In addition to further expansion of the Elwood facility, which is permitted for 3,850 megawatts in generating capacity, including 2,500 megawatts for combined-cycle power development, the Company is pursuing other power generation opportunities.
It will jointly develop and operate, with Exelon Corporation, a 350-megawatt natural gas-fired "peaker" electric plant on Chicago's southeast side.  The plant will provide reliable electricity to the city in times of high electric demand.  It is targeted
to begin operations in late spring 2002.

The Company expects fiscal 2001 equity investment income to increase due to operational commencement of the 750-megawatt expansion of the Elwood facility partially offset by increased partnership interest expense resulting from a project financing
of the entire facility.  Closing on the project financing is expected to occur in the fourth quarter of fiscal 2001.

Midstream Services Segment

The Company is engaged in wholesale activities that provide value to gas distribution marketers, utilities and pipelines.  The Company, through Peoples Gas, operates a natural gas hub.  It also owns and operates, through Peoples Energy Resources
Corp. (PERC), a natural gas liquids peaking facility and is active in other asset-based wholesale activities.  The Company and Enron North America, Inc. ("Enron") are equal partners in enovate, L.L.C. ("enovate"), which is expanding the Peoples Gas hub by
offering additional hub services and peaking services, developing new products and pursuing strategic asset acquisitions.  PERC is also an equal partner in Whitecap Energy System (Whitecap) with ANR Pipeline Company, a subsidiary of the El Paso
Corporation.  Whitecap is a proposed pipeline designed to deliver natural gas to new and existing power plants in Indiana, Illinois and Wisconsin and to serve growth markets in existing gas utility systems.



Operating revenues for the three- and six-month periods increased $9.0 million to $47.6 million and $9.5 million to $87.9 million.  Success in this segment is dependent upon capturing margin in a volatile wholesale market.  The size of this margin
can vary daily and is small in relation to the market value of the commodity.  Therefore, revenue statistics are not necessarily a good indicator of results.  Operating income and equity investment income for the three months ended decreased $798,000 to
$5.0 million. Operating income and equity investment income for the six-month period increased $2.5 million to $10.6 million.  Both periods were positively impacted by the results from the enovate partnership with Enron ($4.8 million and $6.2 million),
partially offset by lower operating income from hub ($2.2 million and $1.7 million) and peaking ($12,000 and $564,000) activities.  Wholesale activities benefited in the prior period from a nonrecurring pipeline construction project ($1.5 million).

The Company's objective is to become the primary player in the Midwest energy market, developing additional hub services such as storage, transportation and title tracking while pursuing an exchange-traded Chicago contract.  The enovate
partnership is anticipated to grow through development of new products and services, development of wholesale business for the Chicago niche marketplace and identification of asset based projects in the Chicago area that have a clear strategic fit.  The
Company expects operating income and equity investment income in fiscal 2001 to increase by at least 10 percent over the prior year.

Retail Energy Services Segment

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

For the three-and six-month periods, operating revenues increased $69.0 million to $115.5 million and $115.4 million to $196.7 million, respectively, due to increased gas sales resulting from higher gas prices and from the start-up of electricity
sales.  Operating income for the second quarter grew to $2.2 million, an increase of $2.3 million over the year ago period.  Fiscal year-to-date results reflect an increase of $1.9 million over the prior period loss of $1.6 million.  The current periods
benefited from increased gas and electric margins, partially offset by higher operating expenses related to growth.  Both current periods also benefited from a one-time change in inventory accounting methods ($1.5 million).

The Company intends to develop proprietary products as it participates in the electric and gas unbundling process and will continue to build the necessary infrastructure to support its growth.  As a result of growing customer base and volumes,
margin enhancement and cost management initiatives, the Company expects that the fiscal year results for this segment will show a smaller loss than last year.

Oil and Gas Production Segment

The Company is active in the acquisition, development and production of oil and gas reserves in selected onshore basins in North America.  The Company also has an investment in EnerVest Energy, L.P. (EnerVest) which acquires, develops and manages
a portfolio of U.S. and Canadian oil and gas producing properties.  The Company's focus is on natural gas, with growth coming from low risk drilling opportunities and the acquisition of proved reserves with upside potential which can be realized through
drilling, production enhancements and reservoir optimization programs.  Certain producing properties owned by the Company qualify for income tax credits as defined in Section 29 of the Internal Revenue Code of 1986.  These credits are computed based on
units of production.



Operating revenues for the three- and-six month periods increased $4.5 million to $10.8 million and $9.7 million to $20.4 million, respectively, due primarily to the impact of new reserve acquisitions subsequent to the year ago periods, positive
results from drilling programs and higher sales prices on production volumes. Operating income and equity investment income for the three months ended increased $1.1 million to $2.8 million due to the higher revenue from production sales offset, in part,
by higher operating expenses ($1.2 million) and increased depletion expense ($820,000).  Equity investment income for the quarter is down due to unexpected operating costs for the recompletion of certain wells and lower production as a result of drilling
delays.  Operating income and equity investment income for the six months ended increased $3.9 million to $6.6 million due to higher revenues from production sales and positive results from the EnerVest partnership ($1.4 million).  Partially offsetting
these gains were higher operating expenses ($2.3 million) and increased depletion expenses ($3.2 million).

The Company's objective is to become a top-fifty owner of natural gas reserves.  Existing oil and gas properties will be developed through drilling and operational enhancements.  The Company will continue to hedge a substantial portion of its
production in order to mitigate price risk and will pursue oil and gas reserve acquisitions that are consistent with its growth strategy.

On April 26, 2001, the Company acquired interests in South Texas properties consisting of approximately 11,500 gross acres (8,900 net) of developed and undeveloped oil and gas leasehold, which will be operated by Peoples Energy Production, the
Company's oil and gas production subsidiary.  The acquired reserves, 91 percent of which are natural gas, were purchased for about $120.0 million.  The transaction increases the Company's total proved reserves to approximately 130 billion cubic feet of
gas equivalent, with current net production capability of approximately 55 million cubic feet of gas equivalent per day.  The Company is responsible for the operation of 32 producing wells.

Operating income in fiscal 2001 is expected to increase due to full year impacts of reserves acquired in 2000, development drilling and the impact of the South Texas acquisition.

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.  The Company has invested in Enertech Capital Partners II, L.P., a venture capital fund specializing
in energy-related and telecommunication entities, providing the opportunity for attractive financial returns along with information regarding new technology developments.  These and certain business development activities do not fall under the above
segments and are reported in the Other segment.  Results for the three- and six-month periods were virtually unchanged from the prior year periods.

Corporate and Adjustments

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

The $1.4 million and $7.5 million decreases in operating income for the three- and six-month periods, respectively, is mainly due to increased operating expenses.  The six-month period reflects the mark-to-market pricing of unrealized liabilities
for stock appreciation rights granted to certain employees under the Company's long-term incentive compensation plans ($4.6 million).  Comparison of results for the three- and six-month periods reflect prior period costs related to the corporate branding
campaign ($968,000 and $2.5 million).



Other Income and Deductions

Other income and deductions for the three- and six-month periods increased by $5.4 million to $6.3 million and $3.8 million to $5.3 million, respectively.  The increases are mainly a result of interest income associated with advances to Elwood
Energy ($1.9 million and $3.2 million), interest income from a note receivable originating from the cancellation of equipment purchases associated with the development of the Company's Calumet site ($1.7 million and $1.7 million) and the benefit from an
interest rate swap ($1.5 million and $1.5 million).  Partially offsetting the effects in the fiscal year-to-date period was a loss on the disposition of equipment associated with development of the Company's Calumet site ($2.8 million).

Other income and deductions for Peoples Gas increased $307,000 to $857,000 for the three-month period.  These variations are primarily a result of increases in imputed interest on amounts recoverable from customers ($676,000).  Offsetting this
effect in part was the prior period's recognition of the allowance for other funds used during construction ($434,000) and a prior period gain on the disposition of property ($114,000).  A decrease was reflected in the fiscal year-to-date period of
$79,000 to $1.2 million.  The decrease was due primarily to the prior period's recognition of the allowance for other funds used during construction ($1.1 million) and a prior period gain on disposition of property ($114,000) offset, in part, by an
increase in imputed interest on amounts recoverable from customers ($986,000).

Other income and deductions for North Shore Gas increased $69,000 to $117,000 and $122,000 to $211,000, for the three- and six-month periods, respectively, due primarily to imputed interest on amounts recoverable from customers ($125,000 and
$184,000) partially offset by miscellaneous interest revenues ($64,000 and $66,000).

Interest Expense

For purposes of the following discussion, long-term obligations refer to instruments with maturity dates over one year, including obligations classified as short-term debt in the balance sheet due to tender provisions.

For the three- and six-month periods, interest expense for the Company increased $5.2 million to $18.9 million and $11.1 million to $36.2 million, respectively.  Short-term interest expense in both periods increased primarily due to increased
working capital needs of the utilities ($3.5 million and $5.4 million) partially offset in the quarter by a decrease in Peoples Energy's corporate short-term interest expense ($1.7 million).  Long-term interest expense increased ($6.2 million and $8.0
million) due to the Company's issuances of long-term debt in July 2000 and January 2001.  Partially offsetting these effects was lower interest on Peoples Gas' long-term debt due to prior year refinancing ($2.6 million and $3.7 million).

Interest expense for the three- and six-month periods increased $963,000 to $10.2 million and $2.3 million to $20.1 million respectively, for Peoples Gas.  The increased interest expense is primarily due to additional working capital required to
pay for gas supply in advance of collections from customers ($3.4 million and $5.1 million).  Peoples Gas issued $200 million in one-year notes to fund these working capital needs.  Interest expense on long-term obligations decreased due to the prior year
refinancing.

Interest expense for North Shore Gas for the three- and six-month periods increased $150,000 to $1.5 million and $319,000 to $2.9 million, respectively, due mainly to additional working capital required to pay for gas supply in advance of
collections from customers ($140,000 and $289,000).

Income Taxes

For the three and six months ended, income taxes for the Company increased $4.3 million to $38.3 million and $7.6 million to $59.0 million, respectively, due mainly to higher pre-tax income.  A partial offset for the fiscal year-to-date period was
an increase of $801,000 in Section 29 tax credits associated with production from certain oil and gas production properties.



Income taxes for Peoples Gas increased $3.0 million to $31.6 million and $12.2 million to $55.8 million for the three- and six-month periods, respectively, due primarily to higher pre-tax income.  For the three- and six-month periods for North
Shore Gas, income taxes increased $431,000 to $4.8 million and $1.3 million to $8.4 million, respectively, due primarily to higher pre-tax income.

Fiscal 2001 Outlook

The Company is raising its earnings per share estimate for fiscal 2001 to range between $3.15 and $3.25, assuming normal weather for the remaining six months of the year, planned utility operations and partial year impacts of the South Texas oil and
gas property acquisition announced in late April.  The financial target for the gas distribution segment is to achieve a 13 percent return on common equity. The target for the diversified business segments is to achieve between 16 percent and 20 percent
of the Company's total earnings from such segments, based on an Earnings Before Income Taxes (EBIT) range of $45.0 million to $55.0 million.

Other Matters

Accounting Standards.  On October 1, 2000 the Company adopted SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended by SFAS No. 137 and SFAS No. 138.  See Note 1 of the Notes to Consolidated
Financial Statements.  The standard involves assessing and recording the effectiveness of a cash flow hedge when incurred and may result in additional volatility in reported earnings.

See the consolidated statement of cash flows and the discussion of major balance sheet fluctuations for more detail.

Balance Sheet Variations

In addition to a comparison of the March 31, 2001 balance sheet to the prior fiscal year ended balance sheet, the Company, Peoples Gas and North Shore Gas have included the comparable March 31, 2000 balance sheet.  Many of the fluctuations between
the current quarter and the prior fiscal year end are due to weather seasonality and volatility in natural gas prices.

The Company's total assets at March 31, 2001 increased $634.4 million, or 25 percent, from September 30, 2000.  The increase was primarily due to a $523.7 million increase in utility customer accounts receivable resulting from historically high
gas prices and an increase of $76.6 million in advances to Elwood Energy for expansion of the peaking facility.  These effects were partially offset by a $62.7 million reduction in gas in storage and a $20.5 million reduction in gas costs recoverable
through rate adjustments.



The utility accounts receivable balances at March 31, 2001 increased $434.7 million to $651.1 million as compared to March 31, 2000 primarily due to the higher unit cost of natural gas and the effects of colder weather.

Peoples Gas and North Shore Gas implemented several payment programs including short-term payment arrangements and more flexible budget plans.  Additionally, the Company has pledged up to $2.0 million dollars to assist eligible low income
customers.  At March 31, 2001 $180.0 million of the utility accounts receivable balances represented amounts owed by customers who were either enrolled in budget plans or had called to establish short-term payment arrangements.  Timing of cash receipts
will be affected by increased use of these plans.  The utilities are vigorously pursuing collection of past-due accounts, and have prioritized its efforts in terms of payment history, arrearage aging and bill size.  The utilities' bad debt reserves at
March 31, 2001 totaled $43.9 million, an increase of $16.2 million from the March 31, 2000 balances.  The Company believes the reserves will be adequate to absorb anticipated increased bad debt write-offs.  However, it is closely monitoring the aging of
receivables and will make adjustments to the reserves if warranted.

The Company's current liabilities rose at March 31, 2001 by $261.4 million from September 30, 2000.  The change was mostly a result of a temporary LIFO liquidation credit ($184.4 million) in the current period due to the anticipated replenishment
of the lower cost LIFO price layer by fiscal year end.  Also affecting the change were increases in accrued taxes ($112.3 million) and accounts payable ($108.5 million) due to higher gas costs offset, in part, by a decrease in short-term debt ($137.8
million).

Variations in the Company's deferred credits and other liabilities and accumulated other comprehensive income are due to the adoption of SFAS No. 133, (See Note 1 of the Notes to Consolidated Financial Statements.)

Total assets of Peoples Gas at March 31, 2001 increased $455.8 million, or 25 percent, from September 30, 2000 primarily due to higher customer accounts receivable ($460.2 million) and prepaid pension costs ($24.7 million).  These increases were
partially offset by a decrease in gas in storage ($55.1 million) due to increased demand during colder weather periods and decreased gas costs recoverable ($17.2 million) resulting from higher gas charges and increased volumes due to colder weather.
Current liabilities increased $402.1 million due to increased accrued taxes ($101.1 million) and to a higher level of accounts payable ($50.7 million) resulting from higher gas costs.  The short-term debt was $88.2 million higher to supplement working
capital needs.  The estimated LIFO liquidation credit ($153.3 million) anticipates the replenishment of the lower cost LIFO price layer by fiscal year end.  The LIFO adjustment was also greater than in the comparable fiscal year period because of
additional withdrawals due to colder weather and higher gas prices.

The accounts receivable at March 31, 2001 for Peoples Gas increased $382.3 million to $574.2 million as compared to March 31, 2000 primarily due to the higher unit cost of natural gas and the effects of colder weather.  The bad debt reserve at
March 31, 2001 totaled $42.1 million, an increase of $15.5 million from the March 31, 2000 balance.  The average gas charge for the current six-month period was 80.65 cents per therm versus 33.18 cents per therm for the prior year period.



Total assets of North Shore Gas at March 31, 2001 increased $56.6 million, or 21 percent, from September 30, 2000 primarily due to higher customer accounts receivable ($63.5 million) offset, in part, by decreased gas in storage ($6.7 million) due
to increased demand during colder weather periods.  Current liabilities increased $49.9 million due to increases in accrued taxes ($10.1 million) and accounts payable ($6.7 million) due to higher gas costs.  The estimated LIFO liquidation credit ($31.2
million) anticipates the replenishment of the lower cost LIFO price layer by fiscal year end.  The LIFO adjustment was also greater than in the comparable fiscal year period because of additional withdrawals due to colder weather and higher gas prices.

The accounts receivable at March 31, 2001 for North Shore increased $52.3 million to $76.9 million as compared to March 31, 2000 primarily due to the higher unit cost of natural gas and the effects of colder weather.  The bad debt reserve at March
31, 2001 totaled $1.8 million, an increase of $700,000 from the March 31, 2000 balance.  The average gas charge for the current six-month period was 80.52 cents per therm versus 34.03 cents per therm for the prior year period.



Financial Sources

In the first quarter, Peoples Gas issued short-term debt of $200 million to supplement working capital needs and replace maturing short-term obligations.  The Company, as of March 31, 2001 has lines of credit of $305.0 millionand had unused credit
available from banks of $277.0 million.  Peoples Gas had $190.0 million of available credit facilities of which $24.0 million was available to North Shore Gas.  At March 31, 2001 Peoples Gas had unused credit available from banks of $162.0 million and
North Shore Gas had unused credit available from banks of $24.0.

In January 2001, the Company issued $325.0 million 6.9% Notes, due January 15, 2011.  In March 2001, the Company commenced an exchange offering for all of its outstanding 6.9% Notes due January 15, 2011, for an equal amount of 6.9% Notes due
January 15, 2011, Series A.

Financial Uses

Capital Spending.  In the six-month period, the Company spent $56.1 million on property, plant and equipment, including partnership investments of $6.5 million.  Peoples Gas and North Shore Gas, which make up the Gas Distribution segment, spent
$39.1 million, and $4.8 million, respectively on property, plant and equipment in the same period.  The remaining $12.2 million was spent by the diversified business segments as follows:  Power Generation $1.4 million; Midstream Services $1.9 million; Oil
and Gas Production $6.4 million and Corporate and Other $2.5 million.

Dividends.  On February 7, 2001, the Directors of the Company voted to increase the regular quarterly dividend on the Company's common stock to 51 cents per share from the 50 cents per share previously in effect.  The annualized dividend rate
now amounts to $2.04 per share.

Contingencies

Environmental Matters.  Peoples Gas and North Shore Gas are conducting environmental investigations and work at certain sites that were the location of former manufactured gas operations.  (See Note 3 of the Notes to Consolidated Financial
Statements.)

In 1994, North Shore Gas has received a demand from a responsible party under 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 in the District Court for the Northern District of Illinois asking the court to declare that North Shore Gas is not liable for response costs relating to the site.  The defendant filed a counterclaim for costs incurred by the
defendant with respect to the site.  (See Note 3 of the Notes to Consolidated Financial Statements.)

Peoples Gas and North Shore Gas are conducting a mercury inspection and remediation program.  (See Note 3 of the Notes to Consolidated Financial Statements.)

Market Risk Management

Commodity Price Risk.  The Company uses forward contracts and financial instruments, including futures, swaps, collars 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.  Except as discussed below for enovate, the Company's policy for risk management activities stipulates that such financial instruments are only to be used for management of price
risk. The Company monitors and controls derivative and related physical positions using a mark-to-market (MTM) analysis.  This analysis provides information on credit exposure as well as the current value of the portfolio.



Peoples Gas and North Shore Gas 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.

Investments by the Company's diversified businesses are subject to a thorough analysis of related market risk and an acceptable plan for each investment 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 MTM reports and established notification policies.

The Company has working interests in natural gas and crude oil producing properties.  Using swaps and options, approximately 80 percent of the production estimated as of March 31, 2001 for the next twelve months is hedged, thereby removing market
risk on that portion of the production.  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
should be substantially offset by an equal gain in value resulting from the financial transaction.  Sensitivity analyses are used 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 March 31, 2001, the sensitivity analysis for oil and gas producing properties demonstrated an instantaneous 10 percent adverse movement in the NYMEX forward curve for natural gas and oil
would have reduced future EBIT by approximately $13.0 million for all proved reserves.

The Company sells fixed price and variable priced products as part of its retail energy services businesses.  Risk is reduced through the use of fixed price supplier contracts that hedge the expected price for monthly volume of customer usage.
Variations in monthly usage from expected can expose the Company to additional price risk.  Risk management trading and optimization of storage assets are utilized to mitigate this intramonth  risk.  As of March 31, 2001, exposure from these activities
was not material.  As of March 31, 2001 the retail energy services segment had no open notional financial positions.

The Elwood partnership owns a natural gas-fired electric generating peaking facility.  Elwood has agreed to sell all of the facility's current generation capacity and energy produced at fixed demand and commodity charges under multi-year
contracts.  The power sales contracts with the customers were renegotiated March 1, 2001 to essentially eliminate fuel price risk.  Therefore, Elwood has no price risk for fuel purchases or power sales during the term of these contracts.

The Company has an equity investment in enovate.  It may participate in trading activities other than for hedging purposes and hold a number of open, uncovered positions.  It is subject to position, dollar and Value at Risk loss limits established
by the Company and Enron through the risk management policy of enovate.  Management believes that these maximum loss limits are at a level such that any adverse results from such trading activity would not have a material adverse effect on the results of
operations or the financial condition of the Company.

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.  The Company currently has outstanding a mix of $502.0 million in variable rate bonds and notes (taxable and tax-exempt) and $28.4 million in
other short-term borrowings. Assuming interest rates are 10 percent higher than the rates reported at the end of March 31, 2001, the Company's annualized interest expense would increase by approximately $2.4 million before considering the effect of income
taxes.

Included in the Company's variable rate debt are its $100.0 million Notes due August 1, 2002.  The Company's interest rate risk has been further reduced due to an interest rate swap effective February 1, 2001, to fix the rate for $75.0 million of
the $100.0 million at 6.8 percent.

Labor Negotiations.

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 business and financial goals regarding its business segments, the effect of weather on net income, cash
position, source of funds, financing activities, market risk, completion of the Elwood facility expansion, the insignificant effect on income arising from changes in revenue from customers' gas purchases from entities other than the gas distribution
utility subsidiaries, and environmental matters.  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, including but not limited to the effect of unusually high gas prices on cost of gas supplies, accounts receivable and the provision for uncollectible accounts, and interest expense;

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

- developments regarding Peoples Gas' and North Shore Gas' mercury investigation and remediation program;

- 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;

- drilling risks and the inherent uncertainty of gas and oil reserve estimates; and

- adverse effects, if any, of a union work stoppage at Peoples Gas.

Some of these uncertainties that may affect future results are discussed in more detail under the captions "Competition and 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 statements.
