**Notes to Condensed Consolidated Financial Statements**

(Unaudited)

The accompanying notes should be read in conjunction with Notes to Consolidated Financial Statements included in NSTAR’s 2003 Annual Report on Form 10-K.

**Note A.  Business Organization and Summary of Significant Accounting Policies**

1.  About NSTAR

NSTAR (or the Company) is an energy delivery company serving approximately 1.4 million customers in 107 cities and towns in Massachusetts, including approximately 1.1 million electric customers in 81 communities and approximately300,000 gas customers in 51 communities.  NSTAR’s retail utility subsidiaries are Boston Edison Company (Boston Edison), Commonwealth Electric Company (ComElectric), Cambridge Electric Light Company (Cambridge Electric) (collectively operating as“NSTAR Electric”) and NSTAR Gas Company (NSTAR Gas).  Reference in this report to “NSTAR” shall mean the registrant NSTAR or one or more of its subsidiaries as the context requires.  Reference in this report to “NSTARElectric” shall mean each of Boston Edison, ComElectric and Cambridge Electric.  NSTAR also has ownership interests in and conducts non-utility, unregulated operations.

2.  Basis of Consolidation and Accounting

The financial information presented as of March 31, 2004 and for the three-month periods ended March 31, 2004 and 2003 has been prepared from NSTAR’s books and records without audit by independent accountants.  However,NSTAR’s independent accountants have performed a review of these interim financial statements in accordance with standards established by the American Institute of Certified Public Accountants.  Financial information as of December 31, 2003 was derivedfrom the audited consolidated financial statements of NSTAR, but does not include all disclosures required by accounting principles generally accepted in the United States of America (GAAP).  In the opinion of NSTAR’s management, all adjustments (which areof a normal recurring nature) necessary for a fair presentation of the financial information for the periods indicated have been included.  Certain immaterial reclassifications have been made to the prior year amounts to conform with the currentpresentation.

The utility subsidiaries are subject to the Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No. 71, “Accounting for the Effects of Certain Types of Regulation” (SFAS 71). The application of SFAS 71 results in differences in the timing of recognition of certain expenses from that of other businesses and industries.  The distribution and transmission businesses remain subject to rate-regulation and continue to meet the criteria forapplication of SFAS 71.

The preparation of financial statements in conformity with GAAP requires management of NSTAR and its subsidiaries to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingentassets and 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 these estimates.

The results of operations for the three-month periods ended March 31, 2004 and 2003 are not indicative of the results that may be expected for an entire year.  Electric energy sales and revenues are typically higher in the winterand summer months than in the spring and fall months, as sales tend to vary with weather conditions.  Gas energy sales and revenues are typically higher in the winter months than during other periods of the year.

3.  Stock Option Plan

NSTAR applies the recognition and measurement principles of Accounting Principles Board Opinion    No. 25, “Accounting for Stock Issued to Employees” and related Interpretations in accounting for its 1997Share Incentive Plan.  Currently, no stock-based employee compensation expense for option grants is reflected in net income, as all options granted under this plan had an exercise price equal to the market value of the underlying common shares on the date ofgrant.  The following table illustrates the effect on net income and earnings per share if NSTAR had applied the fair value recognition provisions of SFAS No. 123, “Accounting for Stock-Based Compensation” to stock-based employeecompensation.

4.  Pension and Other Postretirement Benefits

Pension

NSTAR sponsors a defined benefit retirement plan, the NSTAR Pension Plan (the Plan), that covers substantially all employees.  For the three months ended March 31, 2004, NSTAR has contributed approximately $12 million to thePlan.  The Company anticipates contributing approximately $31 million to the Plan over the remaining nine months.

Effective for the quarter ended March 31, 2004, SFAS No. 132R, “Employers’ Disclosures about Pension and Other Postretirement Benefits,” requires disclosure of the net periodic pension and postretirement benefitcost.

Other Postretirement Benefits

NSTAR also provides health care and other benefits to retired employees who meet certain age and years of service eligibility requirements.  These benefits include health and life insurance coverage and until April 1, 2003,reimbursement of certain Medicare premiums for certain retirees.  Under certain circumstances, eligible retirees are required to make contributions for postretirement benefits.  For the three months ended March 31, 2004, NSTAR has contributed approximately$3.6 million toward these benefits.  The Company anticipates contributing approximately $16 million for these benefits over the remaining nine months.

The net periodic pension and other postretirement benefit costs for the first quarter were estimated based on the latest available participant census data.  A full actuarial valuation will be completed during the secondquarter.  At that time, the cost amounts will be adjusted based on the actual actuarial study results.

In December 2003, the FASB issued Staff Position (FSP) 106-1, “Accounting and Disclosure Requirements related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003” (the Act).  The Act providesfor drug benefits for retirees over the age of 65 under a new Medicare Part D program.  For employers like NSTAR, who currently provide retiree medical programs for former employees over the age of 65, there are potential subsidies available which are inherentin the Act.  The Act potentially entitles these employers to a direct tax-exempt federal subsidy.

In accordance with this FSP, NSTAR elected to defer recognition of the provisions of this Act until further accounting guidance is issued.  As a result, the provisions of the Act are not reflected in this disclosure or in theaccompanying Condensed Consolidated Financial Statements.  Specific authoritative accounting guidance on the accounting for the federal subsidy is pending and that guidance, when issued, could

Table of Contents

require NSTAR to change previously reported amounts related to accumulated benefit obligations and net periodic postretirement benefit costs.

In April 2004, the FASB issued a proposed Staff Position that provides proposed guidance on the accounting for the effects of the Act.  The proposed guidance indicates that, when an employer initially accounts for the subsidy, theeffect on the accumulated postretirement benefit obligation should be accounted for as an actuarial gain (assuming no plan amendments are made).  In addition, since the subsidy would affect the employer’s share of its plan’s costs, the subsidy isincluded in measuring the costs of benefits attributable to current service.  Therefore, the subsidy should reduce service cost when it is recognized as a component of net periodic postretirement benefit cost.  After a comment period, this Staff Position iscurrently expected to be effective in the third quarter of 2004.  NSTAR is evaluating the impact that the ACT and this Staff Position will have on its financial position..

5.  New Accounting Standards

In January 2003, the FASB issued Interpretation No. 46, “Consolidation of Variable Interest Entities,” as revised in December 2003 (FIN 46R), which addresses the consolidation of variable interest entities (VIE) by businessenterprises that are the primary beneficiaries.  A VIE is an entity that does not have sufficient equity investment at risk to permit it to finance its activities without additional subordinated financial support, or whose equity investors lack thecharacteristics of a controlling financial interest.  The primary beneficiary of a VIE is the enterprise with the majority of the risks or rewards associated with the VIE.  This interpretation has two effective dates:  December 31, 2003 and March 31,2004.

NSTAR has a wholly owned special purpose subsidiary, BEC Funding LLC, established to facilitate the sale and administration of $725 million in notes to a special purpose trust created by two Massachusetts state agencies. Historically, NSTAR has consolidated this entity.  As part of NSTAR’s assessment of FIN 46R and for compliance at December 31, 2003, NSTAR reviewed the substance of this entity to determine if it is still proper to consolidate this entity.  Based onits review, NSTAR has concluded that BEC Funding LLC is a variable interest entity and should continue to be consolidated by NSTAR.

For the quarter ended March 31, 2004, NSTAR evaluated, among other entities, its power purchase agreements and determined that it is possible that five counterparties might be considered variable interest entities.   These entitieshave daily capacity output ranging from 20 MW to 330 MW.  For the quarters ended March 31, 2004 and 2003, NSTAR purchased a total of approximately 1,121 MWH and 1,233 MWH, respectively, under these agreements.  These purchases approximate 18% of the totalmegawatts purchased for the quarters ended March 31, 2004 and 2003 and amounted to approximately $102 million and $100 million, respectively.  In order to determine if these counterparties are VIEs and if NSTAR is the primary beneficiary of these counterparties,NSTAR concluded that it needed more information from the entities.  NSTAR attempted to obtain the information required and requested, in writing, these entities provide the Company with the necessary information.  However, all of the entities have indicatedthat they will not provide the requested information as they are not contractually obligated to provide such confidential information.  Since NSTAR was unable to obtain the necessary information and as allowed under a scope exception in FIN 46R, the accompanyingCondensed Financial Statements do not reflect the consolidation of any entities with which NSTAR has a power purchase agreement. 

In March 2004, the FASB issued an Exposure Draft for a Proposed Statement of Financial Accounting Standards, “Share-Based Payment.”  This proposed Statement addresses the accounting for transactions in which a companyreceives employee services in exchange for (a) equity instruments of the company or (b) liabilities that are based on the fair value of the company’s equity instruments or that may be settled by the issuance of such equity instruments.  This proposedStatement would also eliminate the ability to account for share-based compensation transactions using APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and generally would require that such transactions be accounted for using afair-value-based method.  This Exposure Draft is open for public comment until June 30, 2004.  The final Statement is expected to be applied prospectively, for NSTAR, for fiscal years beginning after December

Table of Contents

15, 2004.  NSTAR is currently assessing the impact of this proposed Statement on its share-based compensation programs.

**Note B.  Cost of Removal**

For NSTAR’s regulated utility businesses, cost of removal (negative net salvage) is recognized as a component of depreciation expense in accordance with approved regulatory treatment.  Cost of removal was previously includedin accumulated deprecation but is currently reflected as a regulatory liability.  As of March 31, 2004 and December 31, 2003, the estimated amount of the cost of removal included in

regulatory liabilities was approximately $233 million and $223 million, respectively, based on the cost of removalcomponent in current depreciation rates.

**Note C.  Derivative Instruments - Power Contracts**

NSTAR accounts for its power contracts in accordance with SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (SFAS 133).  NSTAR has six purchased power contracts that contain components withpricing mechanisms that are partly based on a pricing index, such as the Gross National Product or Consumer Price Index.   The recognition of a liability for the fair value of the above-market portion of these contracts at March 31, 2004 and December 31,2003 is approximately $603 million and $666 million, respectively, and is a component of Deferred credits - Power contracts on the accompanying Condensed Consolidated Balance Sheets.  NSTAR has recorded a corresponding regulatory asset to reflect the futurerecovery of the above-market component of these contracts through its transition charge.  Therefore, as a result of this regulatory treatment, the recording of these contracts on its accompanying Condensed Consolidated Balance Sheets does not result in anearnings impact.

NSTAR has other purchased power contracts in which the contract value is significantly above-market.  However, these contracts have met the criteria for the normal purchases and sales exception pursuant to SFAS 133 and have notbeen recorded on the accompanying Condensed Consolidated Balance Sheets.  The above-market portion of these contracts is currently being recovered through the transition charge.  Therefore, NSTAR does not account for these types of capacity and energycontracts, gas supply contracts, or purchase orders for numerous supply arrangements as derivatives.

**Note D.  Other Utility Matters**

1.  Service Quality Indicators

Service quality indicators are established performance benchmarks for identified measures of service quality relating to customer service and billing performance, customer satisfaction, and reliability and safety performance for allMassachusetts utilities.  NSTAR Electric and NSTAR Gas are required to report annually to the Massachusetts Department of Telecommunications and Energy (MDTE) concerning their performance as to each measure and are subject to maximum penalties of up to twopercent of transmission and distribution revenues should performance fail to meet the applicable benchmarks. 

On March 1, 2004, NSTAR Electric and NSTAR Gas filed their 2003 Service Quality Reports with the MDTE that reflected sufficient levels of reliability and performance; the reports indicate that no penalty will be assessed for 2003. The MDTE will review this filing and will likely issue an order later in 2004.  NSTAR monitors its service quality continuously to determine its contingent liability, and if it were determined that a liability has been incurred and is estimable, an appropriateliability would be accrued.  Annually, each NSTAR utility subsidiary makes a service quality performance filing with the MDTE.  Any settlement or rate order that would result in a different liability level from what has been accrued would be adjusted in theperiod that the MDTE issues an order determining the amount of any such liability.

As of March 31, 2004, NSTAR Electric’s and NSTAR Gas’ 2004 performance has exceeded the applicable established benchmarks such that no liability has been accrued for 2004.  However, these

Table of Contents

results may not be indicative of the results that may be expected for the remainder of the year, including the peak demand period anticipated during the summer period.

2.  Regulatory Proceedings

On March 24, 2004, the Federal Energy Regulatory Commission (FERC) set for hearing a joint return on equity (ROE) filing made by participating New England Transmission Owners (NETO), including NSTAR Electric.  The NETO proposalrequested an increase in the base ROE component of the regional and local transmission rates, to be provided under the Regional Transmission Organization for New England  (RTO-NE) open access transmission tariff (OATT) to a single ROE of 12.8% for all regionaland local transmission rates.  Presently, transmission service in New England is provided under a two-tier structure, with the potential for the ROE for local service to be different than regional service for the same transmission provider.  While the FERCset for hearing the base ROE proposal and, consistent with decisions in prior RTOs, FERC approved a ROE adder of 50 basis points, as an incentive for joining an RTO for regional service.  In addition, FERC set for hearing NETO’s proposal for an additional100 basis points applicable to all future transmission expansion.  The NETO maintain that sufficient equity returns are needed to elicit the necessary investments by the transmission owners within an RTO.  Hearings on the base ROE and 100 basis point adderissues will be held in abeyance while settlement negotiations are held before a FERC administrative law judge.

The joint filing among the NETO was made in connection with the proposed formation of RTO-NE by the NETO and Independent System Operator - New England (ISO-NE), the present administrator of the New England Power Pool (NEPOOL) OATT, andis an important and integral component of the agreement to form an RTO for the New England region.

Also, on March 24, 2004, the FERC conditionally approved RTO status for ISO-NE pending the acceptance of certain conditions.  RTO-NE will act as both the regional transmission provider and the tariff administrator with the RTO-NEOATT replacing the NEPOOL OATT.  RTO-NE will also have operational authority over all transmission within the New England region’s bulk electric power system under a longer-term and more stable contractual structure than the current interim agreementbetween the ISO-NE and NEPOOL.  The NETO are seeking rehearing and clarification of certain provisions of the FERC RTO order issued on March 24, 2004.

**Note E.  Income Taxes**

Income taxes are accounted for in accordance with SFAS No. 109, “Accounting for Income Taxes” (SFAS 109).  SFAS 109 requires the recognition of deferred tax assets and liabilities for the future tax effects of temporarydifferences between the carrying amounts and the tax basis of assets and liabilities.  In accordance with SFAS 109, net regulatory assets include $50 million and $50.2 million of deferred tax assets and corresponding amounts in accumulated deferred income taxesthat were recorded as of March 31, 2004 and December 31, 2003, respectively.  The regulatory assets represent the additional future revenues to be collected from customers for deferred income taxes.

**Note F.  Earnings Per Common Share**

Basic earnings per common share (EPS) is calculated by dividing net income, which includes a deduction for preferred dividends of a subsidiary, by the weighted average common shares outstanding during the year.  SFAS No. 128,“Earnings per Share,” requires the disclosure of diluted EPS.  Diluted EPS is similar to the computation of basic EPS except that the weighted average common shares is increased to include the number of dilutive potential common shares.  DilutedEPS reflects the impact on shares outstanding of the deferred (nonvested) shares and stock options granted, adjusted for forfeitures, under the NSTAR 1997 Share Incentive Plan.

The following table summarizes the reconciling amounts between basic and diluted EPS:

**Note G.  Long-Term Debt Redemption / Issuance**

On March 16, 2004, Boston Edison redeemed the entire outstanding balance of $181 million aggregate principal amount of its 7.80% Debentures due March 15, 2023.  The redemption also included payment of an approximate $6.1 millionpremium plus accrued interest.  Subsequent to the end of the quarter, on April 16, 2004, Boston Edison sold $300 million of ten-year fixed rate (4.875%) Debentures.   The net proceeds were used to repay outstanding short-term debt balances, incurred, inpart, to pay the redemption price of the 7.80% Debentures.  The premium paid to redeem the 7.80% Debentures will be amortized over ten years, the life of the new 4.875% Debentures.

For financial reporting purposes, $300 million of short-term Notes payable at March 31, 2004 have been reclassified on the accompanying Condensed Consolidated Balance Sheets as Long-term debt to reflect this transaction.

**Note H.  Segment and Related Information**

For the purpose of providing segment information, NSTAR’s principal operating segments, or its traditional core businesses, are the electric and natural gas utilities that provide energy delivery services in 107 cities and townsin Massachusetts.  NSTAR subsidiaries also supply electricity at wholesale to municipalities.  The unregulated operating segment engages in business activities that include district energy operations, telecommunications and a liquefied natural gasservice.  Amounts shown on the following table include the allocation of NSTAR’s (parent company) results of operations and assets, net of inter-company transactions, and primarily consist of interest charges and investment assets, respectively, to thesebusiness segments.  The allocation of parent company charges is based on an indirect allocation of the parent company’s investment relating to these various business segments.

**Note I.  Commitments and Contingencies**

1.  Environmental Matters

As of March 31, 2004, NSTAR’s subsidiaries are involved in four state-regulated properties (“Massachusetts Contingency Plan, or “MCP” sites”) where oil or other hazardous materials were previously spilledor released.  The NSTAR subsidiaries are required to clean up or otherwise remediate these properties in accordance with specific state regulations.  There are sometimes uncertainties associated with total remediation costs due to the final selection of thespecific cleanup technology and the particular characteristics of the different sites.  Estimates of approximately $0.7 million are included as liabilities in the accompanying Condensed Consolidated Balance Sheets at both March 31, 2004 and December 31,2003.

In addition to the MCP sites, NSTAR subsidiaries also face possible liability as a result of involvement in 12 multi-party disposal sites or third party claims associated with contamination remediation.  NSTAR generally expects tohave only a small percentage of the total potential liability for these sites.  Estimates of approximately $3.4 million are included as liabilities in the accompanying Condensed Consolidated Balance Sheets at both March 31, 2004 and December 31, 2003.

The MCP and multi-party disposal site amounts have not been reduced by any potential rate recovery treatment of these costs or any potential recovery from NSTAR’s insurance carriers.  Prospectively, should NSTAR be allowed tocollect these specific costs from customers, it would record an offsetting regulatory asset and record a credit to operating expenses equal to previously expensed costs.

NSTAR Gas is participating in the assessment or remediation of five former manufactured gas plant (MGP) sites and alleged MGP waste disposal locations to determine if and to what extent such sites have been contaminated and whetherNSTAR Gas may be responsible for remedial action.  The MDTE has

Table of Contents

approved recovery of costs associated with MGP sites over a 7-year period, without carrying costs.  As of both March 31, 2004 and December 31, 2003, NSTAR has recorded a liability of approximately $4.4 million as an estimate forsite cleanup costs for several MGP sites for which NSTAR Gas was previously cited as a potentially responsible party.  A corresponding regulatory asset has been recorded that reflects the future rate recovery for these costs.

Estimates related to environmental remediation costs are reviewed and adjusted periodically as further investigation and assignment of responsibility occurs and as either additional sites are identified or NSTAR’s responsibilitiesfor such sites evolve or are resolved.  NSTAR’s ultimate liability for future environmental remediation costs may vary from these estimates.  Based on NSTAR’s current assessment of its environmental responsibilities, existing legal requirementsand regulatory policies, NSTAR does not believe that these environmental remediation costs will have a material adverse effect on NSTAR’s consolidated financial position, results of operations or cash flows for a reporting period.

2.  Income Tax Matters

On December 24, 2003, NSTAR exited from its investment in RCN and formally abandoned the 11.6 million shares of RCN common stock.  The Company will claim an ordinary loss on its 2003 tax return as opposed to a capital loss thatwould have resulted from a sale of the stock.  The Company’s position relative to the tax consequences of the transaction is supported by an opinion from an independent tax advisor.

The ordinary loss tax treatment results in the Company realizing the benefits represented by the tax asset recorded on its books that resulted from the previous write-down of this asset for financial reporting purposes.  Therequirement for a tax valuation allowance, therefore, no longer exists.  The Company has reversed this reserve as of December 31, 2003.

The Company believes it more likely than not that it is entitled to an ordinary loss deduction.  The Company expects the IRS to review this transaction and it is reasonably possible that the IRS will disagree.  In accordancewith the Company’s tax policy as it relates to uncertain tax positions, the Company has established a loss contingency reserve of approximately $44 million at December 31, 2003.  This amount represents the tax impact to the Company should the ordinary lossultimately be recharacterized to a capital loss.  This reserve is recorded as part of Deferred credits - other on the accompanying Consolidated Balance Sheets.

The Company believes that its position is well supported.  However, if the Company’s position proves incorrect, the Company may be required to make future cash expenditures that may impact NSTAR’s consolidated resultsof operations and cash flows in a future period.

3.  Legal Proceedings

In the normal course of its business, NSTAR and its subsidiaries are involved in certain legal matters, including civil litigations.  Management is unable to fully determine a range of reasonably possible court-ordered damages,settlement amounts, and related litigation costs (“legal liabilities”) that would be in excess of amounts accrued and amounts covered by insurance.  Based on the information currently available, NSTAR does not believe that it is probable that anysuch legal liability will have a material impact on its consolidated financial position.  However, it is reasonably possible that additional legal liabilities that may result from changes in estimates could have a material impact on its results of operations fora reporting period.

**Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A)**

The accompanying MD&A focuses on factors that had a material effect on the financial condition, results of operations and cash flows of NSTAR during the periods presented and should be read in conjunction with the accompanyingcondensed consolidated financial statements and related notes and with the MD&A in NSTAR’s 2003 Annual Report on Form 10-K.

**Overview**

NSTAR (or the Company) is an energy delivery company serving approximately 1.4 million customers in 107 cities and towns in Massachusetts, including approximately 1.1 million electric customers in 81 communities and approximately300,000 gas customers in 51 communities.  NSTAR’s retail utility subsidiaries are Boston Edison Company (Boston Edison), Commonwealth Electric Company (ComElectric), Cambridge Electric Light Company (Cambridge Electric) (collectively operating as“NSTAR Electric”) and NSTAR Gas Company (NSTAR Gas).  Reference in this report to “NSTAR” shall mean the registrant NSTAR or one or more of its subsidiaries as the context requires.  Reference in this report to “NSTARElectric” shall mean each of Boston Edison, ComElectric and Cambridge Electric.  NSTAR also has ownership interests in and conducts non-utility, unregulated operations.

**Cautionary Statement**

**Rate and Regulatory Proceedings**

a.  Service Quality Indicators

Service quality indicators are established performance benchmarks for identified measures of service quality relating to customer service and billing performance, customer satisfaction, and reliability and safety performance for allMassachusetts utilities.  NSTAR Electric and NSTAR Gas are required to report annually to the MDTE concerning their performance as to each measure and are subject to maximum penalties of up to two percent of transmission and distribution revenues shouldperformance fail to meet the applicable benchmarks. 

Table of Contents

On March 1, 2004, NSTAR Electric and NSTAR Gas filed their 2003 Service Quality Reports with the MDTE that reflected sufficient levels of reliability and performance; the reports indicate that no penalty will be assessed for 2003. The MDTE will review this filing and will likely issue an order later in 2004.  NSTAR monitors its service quality continuously to determine its contingent liability, and if it were determined that a liability has been incurred and is estimable, an appropriateliability would be accrued.  Annually, each NSTAR utility subsidiary makes a service quality performance filing with the MDTE.  Any settlement or rate order that would result in a different liability level from what has been accrued would be adjusted in theperiod that the MDTE issues an order determining the amount of any such liability.

As of March 31, 2004, NSTAR Electric’s and NSTAR Gas’ 2004 performance has exceeded the applicable established benchmarks such that no liability has been accrued for 2004.  However, these results may not be indicativeof the results that may be expected for the remainder of the year, including the peak demand period anticipated during the summer period.

b.  Retail Electric Rates

Electric distribution companies in Massachusetts are required to obtain and resell power to retail customers through either standard offer or default service for those who choose not to buy energy from a competitive energysupplier.  Currently, standard offer service is scheduled to be available to eligible customers through February 2005 at prices approved by the MDTE.  The total rate paid by customers taking standard offer service are set at levels so as to guaranteemandatory overall rate reductions required by the Massachusetts Electric Restructuring Act of 1997 (Restructuring Act) (excluding the impact of standard offer service fuel index adjustments).  Currently, new retail customers in the NSTAR Electric serviceterritories and other customers who are no longer eligible for standard offer service and have not chosen to receive service from a competitive supplier are provided default service.  Default service rates are reset every six months (every three months for largecommercial and industrial customers).  The price of default service is intended to reflect the average competitive market price for power.  NSTAR anticipates that upon the expiration of standard offer service, effective March 1, 2005, all customers notpurchasing generation service from competitive retail suppliers will be eligible for default service.  However, Massachusetts officials are considering new deregulation legislation to be effective after March 1, 2005.  NSTAR cannot predict or anticipate theoutcome of this process or its impact on NSTAR or its customers.  As of March 31, 2004 and December 31, 2003, customers of NSTAR Electric had approximately 23% and 26%, respectively, of their load requirements provided by competitive suppliers.

c.  Natural Gas Rates

****

NSTAR Gas generates revenues primarily through the sale and/or transportation of natural gas.  Gas sales and transportation services are divided into two categories: firm, whereby NSTAR Gas must supply gas and/or transportationservices to customers on demand; and interruptible, whereby NSTAR Gas may, generally during colder months, temporarily discontinue service to high volume commercial and industrial customers.  Sales and transportation of gas to interruptible customers do notmaterially affect NSTAR Gas’ operating income because substantially the entire margin for such service is returned to its firm customers as rate reductions.

In addition to delivery service rates, NSTAR Gas’ tariffs include a seasonal Cost of Gas Adjustment Clause (CGAC) and a Local Distribution Adjustment Clause (LDAC).  The CGAC provides for the recovery of all gas supply costsfrom firm sales customers or default service customers.  The LDAC provides for the recovery of certain costs applicable to both sales and transportation customers.  The CGAC is filed semi-annually for approval by the MDTE.  The LDAC is filed annuallyfor approval.  In addition, NSTAR Gas is required to file interim changes to its CGAC factor when the actual costs of gas supply vary from projections by more than 5%.

d.  Regional Transmission Organization (RTO)

On March 24, 2004, the FERC conditionally approved RTO status to the Independent System Operator - New England (ISO-NE), pending the acceptance of certain conditions.  The ISO-NE will be transformed into an RTO through a change ofname and governance structure, designed to ensure independence from market participants.  RTO-NE will be responsible for the day-to-day operation of New England’s bulk generation and transmission systems, together with the utility companies that owntransmission facilities in New England including NSTAR, filed a proposal with FERC creating a RTO in compliance with FERC directives and pronouncements. 

RTO-NE will be an independent entity, without a financial interest in the region’s marketplace, having operating authority over the New England transmission grid and have the responsibility to make impartial decisions on thedevelopment and implementation of market rules.  The new RTO will enter into a series of contractual arrangements that will define its functions and responsibilities, including a Transmission Operating Agreement, which will govern the relationship between theowners of transmission facilities, such as NSTAR Electric and the RTO, as the operator of the New England transmission grid.  Separate agreements will govern the operation of the spot power and related markets, and merchant transmission facilities. Management cannot estimate the impact of this approval on the Company.

**Other Legal Matters**

In the normal course of its business, NSTAR and its subsidiaries are involved in certain legal matters, including civil litigations.  Management is unable to fully determine a range of reasonably possible court-ordered damages,settlement amounts, and related litigation costs (“legal liabilities”) that would be in excess of amounts accrued and amounts covered by insurance.  Based on the information currently available, NSTAR does not believe that it is probable that anysuch legal liability will have a material impact on its consolidated financial position.  However, it is reasonably possible that additional legal liabilities that may result from changes in estimates could have a material impact on its results of operations fora reporting period.

**Other Events**

NSTAR previously disclosed in its Annual Report on Form 10-K for the year ended December 31, 2003 that NSTAR Electric had initiated a process to auction off certain power purchase agreements under which the Company had contracted topurchase approximately 1,100 megawatts of power under long-term contracts with non-utility generators.  The auction is intended to further NSTAR’s efforts to mitigate stranded costs, which continue to be recovered from customers.  Currently, theauction process is closed and NSTAR is evaluating bids and has begun negotiations with certain parties that, if successful, will lead to a restructuring or buy-out of one or more of these contracts.

Net income was $49.7 million for the quarter ended March 31, 2004 compared to $42.3 million for the same period in 2003.  Factors that contributed to the $7.4 million, or 17.5%, increase in 2004 earnings include additional revenuereceived as part of a reconciliation rate adjustment mechanism related to pension and postretirement benefits other than pensions (PBOP), additional revenue related to a cost reconciliation true-up adjustment, higher electric distribution revenues, interest savingson the Company’s outstanding indebtedness due to lower short-term and long-term interest, and a reduction in operations and maintenance expense.

For the first quarter of 2004, NSTAR generated $78.6 million of cash from operations to fund approximately $49.7 million of net capital expenditures, and $29.9 million of cash dividends.  In comparison to the same period of theprior year, cash from operations increased slightly due to higher earnings offset by the timing of the collection of energy costs.  Financing activities include the retirement of $181 million of the 7.80% series of Debentures.  This retirement wastemporarily funded with short-term borrowings pending a long-term financing, which was completed in April 2004.

The 1.6% increase in retail MWH sales in the first quarter of 2004 reflects, by customer sectors, an improvement of 2.9% in commercial sales offset somewhat by the continued sales decline of 0.9% in the industrial sector.  The 0.6%decrease in firm gas sales in the first quarter of 2004 primarily reflects warmer overall temperatures than in 2003.   Electric and gas sales both reflect the impact of one additional day in 2004 due to the leap year.

Table of Contents

In terms of customer sectors, industrial sales are less sensitive to weather while residential and commercial sales are influenced by temperature extremes.  Despite the overall warmer winter weather in 2004, the increase inelectric sales is attributable in part to commercial building and expansion of existing units and the resulting extension of commercial energy uses, while residential electric sales were unchanged due to warmer weather.  Electric residential and commercialcustomers were approximately 33% and 59%, respectively, of NSTAR’s total retail sales mix for the first quarter of 2004 and provided 53% and 42% of distribution revenues, respectively.  Refer to the “Electric revenues” section below for a moredetailed discussion.  Industrial sales are primarily influenced by national and local economic conditions and sales to these customers further declined in 2004 primarily due to a slowdown in economic conditions that led to reduced production or facilityclosings.

  Electric revenues

Electric retail distribution revenues primarily represent charges to customers for the Company’s recovery of its capital investment, including a return component, and operation and maintenance related to its electric distributioninfrastructure.  The transmission revenue component represents charges to customers for the recovery of costs to move the electricity over high voltage lines from the generator to the Company’s substations.  The increase in retail revenues primarilyreflects the 1.6% increase in retail

Table of Contents

MWH sales substantially all in the commercial sector.  Retail electric revenues also include approximately $5.1 million in additional revenues received as part of a reconciliation rate adjustment mechanism related to pension andPBOP.

NSTAR’s largest earnings sources are the revenues derived from distribution rates approved by the MDTE.  The level of distribution revenues is affected by weather conditions and the economy.  Weather conditions affectsales to NSTAR’s residential and small commercial customers.  Economic conditions affect NSTAR’s large commercial and industrial customers. 

Energy, transition and other revenues primarily represent charges to customers for the recovery of costs incurred by the Company in order to acquire the energy supply on behalf of its customers and a transition charge for recovery ofthe Company’s prior investments in generating plants and the costs related to long-term power contracts.  The energy supply revenues relate to customers being provided energy supply under either standard offer or default service.  Energy supplycontract prices vary among the NSTAR Electric companies and for standard offer and default service customers.  However, the retail revenues related to standard offer and default services are fully reconciled to the costs incurred and have no impact onNSTAR’s consolidated net income. Furthermore, energy and transition revenues are fully reconciled with the cost currently recognized by the Company and, as a result, do not have an effect on the Company’s earnings.  Other revenues primarily relate tothe Company’s ability to effectively reduce stranded costs (mitigation incentive), rental revenue from electric property and annual cost reconciliation true-up adjustments.  In 2004, the cost reconciliation true-up adjustments increased revenues byapproximately $4.7 million.  The $34.6 million increase in energy, transition and other revenues is primarily attributable to higher rates for default service and standard offer service, which include the ComElectric and Cambridge Electric standard offer servicefuel index adjustments.

Wholesale revenues relate to services provided to municipalities and certain other governmental authorities.  This decrease in 2004 wholesale revenues reflects the expiration of two wholesale power supply contracts in January andMarch of 2003.  After October 31, 2005, NSTAR Electric anticipates it will no longer have contracts for the supply of wholesale power.  Amounts collected from wholesale customers are credited to retail customers through the transition charge. Therefore, the expiration of these contracts will have no impact on results of operations.  In October 2004, a municipal wholesale electric contract will expire resulting in a further decline in wholesale revenues and sales.

  Gas revenues

Firm and transportation gas revenues primarily represent charges to customers for NSTAR Gas’ recovery of costs of its capital investment in its gas infrastructure, including a return component, and for the recovery of costs forthe ongoing operation and maintenance of that infrastructure.  The transportation revenue component represents charges to customers for the recovery of costs to move the natural gas over pipelines from gas suppliers to take stations located within NSTARGas’ service area.  The $1.4 million increase in firm and transportation revenues is attributable to additional customers and includes approximately $0.9 million in additional revenues received as part of a reconciliation rate adjustment mechanism relatedto the pension and PBOP.

Energy supply and other gas revenues primarily represent charges to customers for the recovery of costs to the Company in order to acquire the natural gas in the marketplace and a charge for recovery of the Company’s gas supplierservice costs.  This revenue increase of $7.3 million primarily reflects the higher costs of gas supply that reflected a weighted average cost of gas per therm increase over the same period in 2003 of approximately 16%.  These revenues are fully reconciledwith the cost currently recognized by the Company and, as a result, do not have an effect on the Company’s earnings.

Table of Contents

  Unregulated operations revenues

Unregulated operations revenues are derived from NSTAR’s businesses that include district energy operations and telecommunications.  Unregulated revenues were $37.0 million in the first three months of 2004 compared to $34.8million in the same period of 2003, an increase of $2.2 million, or 6%.  The increase in unregulated revenues is primarily the result of an increase in the rates for electric and chilled water services and higher steam revenues resulting from the significantlycolder weather in January.

Operating expenses

Purchased power costs were $333.5 million in the first quarter of 2004 compared to $304.5 million in the same period of 2003, an increase of $29.0 million, or 10%.  The increase is primarily the result of increased sales and thehigher costs of fuel, partially offset by the recognition of $15.1 million relating to the recovery of deferred standard offer and default service supply costs.  NSTAR Electric adjusts its rates to collect the costs related to energy supply from customers on afully reconciling basis.  Due to the rate adjustment mechanisms, changes in the amount of energy supply expense have no impact on earnings.

The cost of gas sold, representing NSTAR Gas’ supply expense, was $137.6 million in the first quarter of 2004 compared to $130.1 million in 2003, an increase of $7.5 million, or 6%, due to recognition of the higher costs of gassupply.  NSTAR Gas maintains a flexible resource portfolio consisting of gas supply contracts, transportation contracts on interstate pipelines, market area storage and peaking services. However, these expenses are also fully reconciled to the current level ofrevenues collected.

Operations and maintenance expense was $106.5 million in the first quarter of 2004 compared to $109.8 million in the same period of 2003, a decrease of $3.3 million, or 3%.  This decrease reflects a reduction in benefits expensesand lower labor costs.

Depreciation and amortization expense was $65.5 million in the first quarter of 2004 compared to $62.1 million in the same period of 2003, an increase of $3.4 million or 5%.  The increase primarily reflects higher depreciabledistribution and transmission plant in service, as well as an increase to the transmission depreciation rate, and increased expense related to software and merger costs to achieve amortization.

DSM and renewable energy programs expense was $17.5 million in the first quarter of 2004 compared to $16.9 million in the same period of 2003, an increase of $0.6 million, or 4%, which are consistent with the collection of conservationand renewable energy revenues.  These costs are in accordance with program guidelines established by the MDTE and are collected from customers on a fully reconciling basis. 

Property and other taxes were $28.8 million in the first quarter of 2004 compared to $26.4 million in the same period of 2003, an increase of $2.4 million, or 9%.  This increase was due to higher overall municipal property taxes of$1.5 million caused primarily by higher property assessments, capital additions and tax rates in the City of Boston.  The overall level of municipal property taxes paid by NSTAR has increased due to legislation passed in Massachusetts allowing for the temporaryshift of property tax burdens from residential to commercial property owners.

Income taxes attributable to operations were $33.1 million in the first quarter of 2004 compared to $28.5 million in the same period of 2003, an increase of $4.6 million, or 16%, reflecting higher pre-tax operating income in2004.

Interest charges

Interest on long-term debt and transition property securitization certificates was $36.5 million in the first quarter of 2004 compared to $40.5 million in the same period of 2003, a decrease of $4.0 million, or 10%.  The decreasein expense primarily reflects the absence of $2.1 million in 2004 resulting from the

Table of Contents

retirement of Boston Edison’s $150 million 6.80% Debentures in March 2003, the retirement of Boston Edison’s $181 million 7.80% Debentures on March 15, 2004 that lowered expense by $0.6 million and the lower principalbalance of transition property securitization certificates outstanding that resulted in reduced interest expense of $1.1 million.  Securitization interest represents interest on debt of BEC Funding collateralized by the future income stream associated primarilywith the stranded costs of the Pilgrim Unit divestiture.  The future income stream was sold to BEC Funding by Boston Edison.  These certificates are non-recourse to Boston Edison.  Partially offsetting these interest declines was additional interestexpense of $719,000 on ComElectric’s Term Loan issued on May 14, 2003 ($150 million, three-year, variable rate)(1.895% at March 31, 2004). 

Short-term and other interest expense was $1.9 million in the first quarter of 2004 compared to $3.0 million in the same period of 2003, a decrease of $1.1 million, or 37%.  The decrease in short-term and other interest expenseprimarily relate to a reduction in bank service fees and other charges ($1.1 million) resulting from a reduction in NSTAR’s revolving credit agreements.  Despite a higher level of debt outstanding of $258.8 million as compared to $223.6 million for thethree-month periods ended March 31, 2004 and 2003, respectively, due to the early debt redemption mentioned above, interest charges were less than the prior year due to lower bank borrowing rates that averaged 1.09% through March 2004 as compared to 1.49% in the sameperiod of last year.  This decreased short-term borrowing costs by $321,000.

On April 16, 2004, Boston Edison paid down short-term debt with the net proceeds of its issuance of $300 million of ten year, 4.875% debentures.

Allowance for funds used during construction/capitalized interest decreased nearly $1.0 million, or 75%, in the first quarter of 2004 primarily due to a lower average balance of construction work in progress as compared to the sameperiod in 2003 due to the completion of construction in December 2003 of combustion turbines at AES’ MATEP facility.

****

**Liquidity and Capital Resources**

NSTAR’s primary uses of cash in the first quarter of 2004 include capital expenditures, dividend payments, debt reductions, minimum lease commitments, electric capacity charge obligations under contracts and natural gascontractual agreements.

Operating activities in the first quarter of 2004 provided $78.6 million of cash.  The Company used $52.5 million in its investing activities, primarily to fund plant expenditures, which included system reliability infrastructureimprovement projects incurred by NSTAR Electric and NSTAR Gas operations.

Operating Activities

The net cash provided by the first quarter of 2004 operating activities of $78.6 million was partially attributable to net income of $49.7 million, which, when adjusted for depreciation and amortization, deferred income taxes andinvestment tax credits, provided $152.7 million of cash as compared to $128.8 million in the same period of 2003 from net income as similarly adjusted.  Deferred income taxes and investment tax credits increased by $13.2 million reflecting the deferred taximpact of a change in the tax laws that allows for an additional 50% acceleration of tax depreciation on current year additions.  In February 2003, the tax law allowance was for only 30% accelerated tax depreciation on current year additions.  Major driversto decreased working capital are a decrease in accounts payable of approximately $55 million year-to-year due to the timing of energy supply invoices and decreased recovery of energy costs of approximately $16 million year-to-year.  There is no impact onearnings from the timing of the recovery of energy costs other than the accrued costs on outstanding balances.  These decreases were offset by an increase in accounts receivable and unbilled revenues of approximately $20 million year-to-year due to the increasedenergy consumption during the quarter and reduced pension contributions year-to-year of approximately $24 million.  NSTAR currently anticipates that it will contribute

Table of Contents

approximately $43 million to its Pension Plan and approximately $23 million to its other postretirement benefit plans in 2004.

Investing Activities

The net cash used in investing activities in the first quarter of 2004 of $52.5 million consists primarily of capital expenditures related to transmission and distribution systems.

Financing Activities

The net cash used in financing activities in the first quarter of 2004 of $26.8 million reflects long-term debt redemptions and sinking funds payments of $201.2 million, dividends paid of $29.9 million and a higher level of short-termborrowings of $204.3 million.

NSTAR is continuing the regulatory filing process to obtain approval to construct a 345 kv transmission line from the southern suburbs of Boston to South Boston in order to assure continued reliability of service and improve power inputcapacity in the Northeast Massachusetts area (NEMA).  If approved, construction is estimated to begin in the fourth quarter of 2004 and the new transmission line is anticipated to be placed in service during the summer of 2006.  This project is a regionaltransmission investment and, as a result, the cost will be shared by all of New England and recovered in rates by NSTAR.  This proposed plan is subject to siting and license requirements. 

Short-Term Financing Activities

NSTAR’s short-term debt increased by $204.3 million to $443.4 million at March 31, 2004 (reflected as $143.4 million on the March 31, 2004 Consolidated Balance Sheet as a result of a reclassification, for financial reportingpurposes,) as compared to $239.1 million at December 31, 2003.  The increase resulted primarily from additional borrowings to redeem $181 million of long-term debentures.

On March 16, 2004, Boston Edison redeemed the entire $181 million aggregate principal amount of its 7.80% Debentures due March 15, 2023.  The redemption included payment of an approximate $6.1 million premium plus accruedinterest. 

Management continuously reviews its capital expenditure and financing programs.  These programs and, therefore, the forecasts included in NSTAR’s 2003 Form 10-K are subject to revision due to changes in regulatoryrequirements, operating requirements, environmental standards, availability and cost of capital, interest rates and other assumptions.

**Sources of Additional Capital and Financial Covenant Requirements**

NSTAR and Boston Edison have no financial covenant requirements under their respective long-term debt arrangements.  ComElectric, Cambridge Electric and NSTAR Gas have financial covenant requirements under their long-term debtarrangements and were in compliance at March 31, 2004 and December 31, 2003.  NSTAR’s long-term debt other than the Mortgage Bonds of NSTAR Gas is unsecured.

The Transition Property Securitization Certificates issued by Boston Edison’s subsidiary, BEC Funding, LLC, are collaterized with a securitized regulatory asset that was sold to BEC Funding with a balance of $408.3 million and$425.4 million as of March 31, 2004 and December 31, 2003, respectively.  Boston Edison, as servicing agent for BEC Funding, collected $25.2 million in the first quarter of 2004.  These collected funds are remitted daily to the trustee of BEC Funding. These Certificates are non-recourse to Boston Edison.

NSTAR has a credit facility that consists of a three year, $175 million revolving credit agreement that expires on November 14, 2005.  At March 31, 2004 and December 31, 2003, there were no amounts outstanding under these revolvingcredit agreements.  The $175 million credit facility serves as a backup to NSTAR’s $175 million commercial paper program that, at March 31, 2004 and December 31, 2003, had $74.5 million and $1.5 million outstanding, respectively.  Under the terms ofthis credit agreement, NSTAR is required to maintain a maximum total consolidated debt to total capitalization ratio of not greater than 65% at all times, excluding Transition Property Securitization Certificates, and excluding Accumulated other comprehensive income(loss) from Common equity, and to maintain a ratio of consolidated earnings before interest and taxes to consolidated total interest expense of not less than 2 to 1 for each period of four consecutive fiscal quarters.  Commitment fees must be paid on the totalagreement amount.  At March 31, 2004 and December 31, 2003, NSTAR was in full compliance with all of the aforementioned covenants.

In December 2003, Boston Edison filed a shelf registration with the SEC to allow Boston Edison to issue up to $500 million in debt securities.  The registration went effective on January 9, 2004.  On April 1, 2004, the MDTEapproved the issuance by Boston Edison of up to $500 million of debt securities from time to time on or before December 31, 2005.  As of March 31, 2004, no amounts were issued under this shelf registration.  On April 16, 2004, Boston Edison sold $300million of ten-year fixed rate (4.875%) Debentures.  The net proceeds were used to repay outstanding short-term debt balances.  For financial reporting purposes, $300 million of short-term Note payable at March 31, 2004, has been reclassified on theaccompanying Condensed Consolidated Balance Sheets as Long-term debt to reflect this transaction. 

Boston Edison has approval from the FERC to issue short-term debt securities from time to time on or before December 31, 2004, with maturity dates no later than December 31, 2005, in amounts such that the aggregate principal does notexceed $350 million at any one time.  Boston Edison has a $350 million revolving credit agreement that expires on November 10, 2004.  At March 31, 2004 and December 31, 2003, there were no amounts outstanding under this revolving credit agreement.

Historically, NSTAR and its subsidiaries have had a variety of external sources of financing available, as indicated above, at favorable rates and terms to finance its external cash requirements.  However, the availability of suchfinancing at favorable rates and terms depends heavily upon prevailing market conditions and NSTAR’s or its subsidiaries’ financial condition and credit ratings.

Table of Contents

An adverse change in NSTAR’s or its subsidiaries’ credit ratings or market conditions could have an adverse impact on the terms and conditions upon which NSTAR or its subsidiaries have access to capital markets.  NSTARhas no financial guarantees, commitments, debt or lease agreements that would require a change in terms and conditions, such as acceleration of payment obligations, as a result of a change in its credit rating.  However, NSTAR’s subsidiaries could berequired to provide additional security for power supply contract performance, such as a letter of credit for their pro-rata share of the remaining value of such contracts.  Refer to “Performance Assurances from Electricity and Gas Supply Agreements”and “Financial and Performance Guarantees” as disclosed in NSTAR’s Annual Report on Form 10-K for the year ended December 31, 2003.

NSTAR’s goal is to maintain a capital structure that preserves an appropriate balance between debt and equity.  Based on NSTAR’s key cash resources available as discussed above, management believes its liquidity andcapital resources are sufficient to meet its current and projected requirements.

**Item 3.  Quantitative and Qualitative Disclosure about Market Risk**

****

**Item 4.  Controls and Procedures**

NSTAR’s disclosure controls and procedures are designed to ensure that information required to be disclosed in reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized andreported within the time periods specified in the rules and forms of the Securities and Exchange Commission.

NSTAR carried out an evaluation, under the supervision and with the participation of NSTAR’s management, including NSTAR’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operationof NSTAR’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15 as of the end of the period covered by this report.  Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that NSTAR’sdisclosure controls and procedures were effective (1) to timely alert them to material information relating to NSTAR’s information required to be disclosed by NSTAR in the reports that it files or submits under the Securities Exchange Act of 1934 and (2) toensure that appropriate information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

**Part II.  Other Information**

****

**Item 1.  Legal Proceedings**

In the normal course of its business, NSTAR and its subsidiaries are involved in certain legal matters, including civil litigation.  Management is unable to fully determine a range of reasonably possible court-ordered damages,settlement amounts, and related litigation costs (“legal liabilities”) that would be in excess of amounts accrued and amounts covered by insurance.  Based on the information currently available, NSTAR does not believe that it is probable that anysuch legal liability will have a material impact on its consolidated financial position.  However, it is reasonably possible that additional legal liabilities that may result from changes in estimates could have a material impact on its results of operations fora reporting period.
