NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



The following Notes present information on both Duquesne Light Holdings,
Inc. (Holdings) and Duquesne Light Company (Duquesne Light). Information on Holdings and its subsidiaries (not including Duquesne Light and its subsidiaries) shall not be deemed to be included as part of Duquesne Lights Notes.



References in the Notes to we, us and our
are to Holdings and its subsidiaries, collectively.



1. ACCOUNTING POLICIES



Consolidation



Holdings is an energy services holding company. Our subsidiaries include
those discussed below.



The consolidated financial statements
of Holdings and Duquesne Light include their accounts and their wholly and majority owned subsidiaries. The equity method of accounting is used for 20% to 50% interests in other companies. Under the equity method, original investments are recorded
at cost and adjusted by our share of undistributed earnings or losses of these companies. All material intercompany balances and transactions have been eliminated in the consolidation.



In addition, effective March 31, 2004, we consolidate variable interest entities for which we are the primary
beneficiary in accordance with Financial Accounting Standards Board (FASB) Interpretation No. 46, Consolidation of Variable Interest Entities (revised December 2003) (FIN 46), regardless of the ownership percentage held by us.



Continuing Operations



Duquesne Light, our largest subsidiary, is an electric utility engaged in
the supply (through its provider-of-last-resort service (POLR)), transmission and distribution of electric energy.



Duquesne Power, L.P., an unregulated subsidiary, maintains a portfolio of energy commodity contracts to provide full-requirements energy supply contracts
for both (i) Duquesne Lights residential and small commercial POLR customers and (ii) Duquesne Light Energy, LLCs large commercial and industrial customers. These energy commodity contracts are with unrelated parties and
include payment guarantees from Holdings.



Duquesne Light
Energy, LLC (DLE) is an unregulated, competitive, retail electric generation supplier that offers customized solutions tailored to meet its customers specific electricity needs. DLEs primary focus is on the large commercial and
industrial customer market segment in Duquesne Lights service territory.



Duquesne Energy Solutions, LLC (DES) is an energy facilities management company that provides energy outsourcing solutions including operation and maintenance of energy and synthetic fuel facilities.



DQE Financial Corp. owns, operates and maintains landfill gas collection and
processing systems, and is an investment and portfolio management organization focused on structured finance and alternative energy investments.



DQE Communications, LLC owns, operates and maintains a high-speed, fiber optic based network, and leases dark fiber from the network to commercial,
industrial and academic customers.



DQE Capital Corporation
provides financing to Holdings for use with its affiliates.



Discontinued
Operations



During 2003, AquaSource, Inc. (formerly our
water resource management subsidiary) completed the sale of its assets, pursuant to agreements entered into in 2002. We sold the propane distribution business of our subsidiary, Pro Am, Inc., in December 2002. (See Note 8.)



Basis of Accounting



Holdings and Duquesne Light are subject to the accounting and reporting requirements of the Securities and Exchange
Commission (SEC). Duquesne Lights electricity delivery business is also subject to regulation by the Pennsylvania Public Utility Commission (PUC) and the Federal Energy Regulatory Commission (FERC) with respect to rates for delivery of
electric power, accounting and other matters.



The electricity
delivery business segment meets the criteria of Statement of Financial Accounting Standards (SFAS) No. 71, Accounting for the Effects of Certain Types of Regulation, and accordingly reflects regulatory assets and liabilities
consistent with cost-based ratemaking regulations. The regulatory assets represent probable future revenue, because provisions for these costs are currently included, or are expected to be included, in charges to electric utility customers through
the ratemaking process. The majority of these assets are currently being recovered over a period of approximately 26 years and are not earning a rate of return.



Pursuant to the PUCs final restructuring order, generation-related transition costs were being recovered through a competitive transition charge
(CTC) collected in connection with providing transmission and distribution services. This collection period ended in the third quarter of 2005 when the remaining CTC balance was collected from the last customer class.

---

The preparation of financial statements in conformity with accounting principles generally accepted in
the United States of America requires management to make estimates and assumptions with respect to values and conditions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of
the financial statements. The reported amounts of revenues and expenses during the reporting period also may be affected by these estimates and assumptions. Management evaluates these estimates on an ongoing basis, using historical experience and
other methods considered reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from these estimates.



The interim financial information for the three and nine month periods ended September 30, 2005 and 2004 is unaudited and has been prepared on the
same basis as the audited financial statements. In the opinion of management, such unaudited information includes all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the interim information. This
information does not include all footnotes which would be required for complete annual financial statements in accordance with accounting principles generally accepted in the United States of America.



These statements should be read with the financial statements and notes
included in our Annual Report on Form 10-K for the year ended December 31, 2004 filed with the SEC. The results of operations for the three and nine months ended September 30, 2005, are not necessarily indicative of the results that
may be expected for the full year.



Recent Accounting Pronouncements



Share-Based Payments



In December 2004, the FASB issued SFAS No. 123R, Share-Based
Payment (revised December 2004), which will eliminate the use of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees. SFAS 123R requires entities to recognize the cost of employee services
received in exchange for awards of equity instruments based on the grant-date fair value of those awards. This standard is effective at the beginning of the first fiscal year that begins after June 15, 2005. We are currently evaluating the
impact of the adoption of this standard on our financial statements.



Accounting for Conditional Asset Retirement Obligations



In March 2005, the FASB issued Financial Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations  an interpretation of FASB Statement No. 143, which clarifies that
the term conditional asset retirement obligation refers to a legal obligation to perform an asset retirement activity. This interpretation also states that the fair value of a liability for the conditional asset obligation should be
recognized when incurred. This interpretation is effective no later than the end of the fiscal year ending after December 15, 2005. We are currently evaluating the impact of the adoption of this standard on our financial statements.



Earnings Per Share



Basic earnings per share are computed on the basis of the weighted average number of common shares outstanding. Diluted
earnings per share are computed on the basis of the weighted average number of common shares outstanding, plus the effect of the outstanding Employee Stock Ownership Plan shares, Holdings preferred stock, stock options and performance share awards.
The treasury stock method is used in computing the dilutive effect of stock options. This method assumes any proceeds obtained upon the exercise of options would be used to purchase common stock at the average market price during the period. The
following tables present the numerators and denominators used in computing the diluted earnings per share from continuing operations for Holdings for the three and nine months ended September 30, 2005 and 2004.

2. RATE MATTERS



Effective January 1, 2005, Duquesne Light joined PJM Interconnection
(PJM), becoming (along with other electric generation suppliers) a load-serving entity within PJM. In addition, POLR III became effective on that date.



As previously reported, the FERC has issued a series of orders eliminating the regional through and out rates (RTOR) for certain transmission services
between the Midwest Independent System Operator (MISO) and PJM effective December 1, 2004. A transitional pricing mechanism called the seams elimination charge adjustment (SECA) has been put in place through March 2006 in order to compensate
transmission owners for the estimated revenue lost as a result of the elimination of the RTOR. Total SECA charges for the Duquesne Light zone are expected to be approximately $39 million. The FERC has accepted revised compliance filings
implementing SECA charges among load-serving entities within the Duquesne Light zone. Under that filing, Duquesne Light was allocated approximately $11 million of the SECA charges. The other load-serving entities in the Duquesne Light zone were
allocated the remainder of such charges. DLEs allocation of SECA charges will depend on the amount of load it serves; based on current load, DLEs allocation is expected to be approximately $1.8 million.



The SECA charges must be paid by load-serving entities within the Duquesne
Light zone on a current basis. In June 2005, Duquesne Light filed a request with the PUC for permission to pass SECA charges through to its POLR customers. This request was granted by the PUC in August 2005, subject to disposition of any complaints
filed against the request. Duquesne Light has put these charges into effect for service beginning August 26, 2005. However, if the FERC ultimately adopts a SECA level and allocation method that differs from the proposed charges initially
accepted by the FERC for billing purposes, refunds or surcharges will be used to compensate or charge the appropriate entity for the difference between the amounts initially accepted by the FERC and the amounts ultimately determined to be just and
reasonable by the FERC. The final amount of our SECA obligations therefore remains uncertain.



As of September 30, 2005, Duquesne Light has reflected SECA charges totaling $6.7 million on the condensed consolidated balance sheets in regulatory assets.

4. DERIVATIVE INSTRUMENTS



Energy Contracts



Beginning January 1, 2005, our supply business is responsible for
providing all of the energy requirements for both (i) residential and small commercial POLR customers and (ii) any customers with whom DLE contracts. To meet this obligation, we entered into energy commodity contracts with multiple
investment-grade suppliers for a significant portion of our expected customer requirements. These purchase contracts are designed solely to provide for the delivery of energy as needed to supply customer usage. A Board-approved risk management
policy permits transactions for the prudent management of customer energy requirements, and precludes any speculative transactions.



The accounting for these contracts considers the provisions of SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities, as amended and interpreted. Under the terms of the contracts, some of the energy purchases are delivered to the Duquesne Light zone as defined by PJM. These purchases qualify for the normal purchase and sale exemption under SFAS
No. 133 and are reflected as purchased power expense in the condensed consolidated statements of income at their wholesale price upon delivery to us. As of September 30, 2005, the remaining notional value of these contracts was $414.2
million, including $372.7 million for the contracts that mature after December 31, 2005.



We also entered into certain purchase contracts that are for delivery to points other than the Duquesne Light zone within PJM. Because these contracts are
not settled at the Duquesne Light zone, they do not qualify for the normal purchase and sale exemption and are recorded in the condensed consolidated financial statements at fair value. Subsequent changes in the fair value of these contracts are
recorded currently in earnings unless certain hedge accounting criteria are met. The remaining notional amount of these contracts as of September 30, 2005, is $372.1 million, including $353.4 million for the contracts maturing after
December 31, 2005. The above amounts include contracts maturing after December 31, 2005 with aggregate notional values of $97.5 million that have been designated as cash flow hedges. To the extent the hedges are determined to be effective,
and certain other criteria are met, the changes in the value of these contracts are included in the statement of comprehensive income, net of deferred taxes. Amounts recorded in the statement of comprehensive income related to cash flow hedges will
be recognized in earnings as the related contracts are settled.



We entered into sales contracts maturing in 2005 through 2007 that are accounted for on a mark-to-market basis. The notional amount of these sales contracts was $184.9 million as of September 30, 2005. These contracts were entered
into primarily for the purpose of offsetting volatility associated with the mark-to-market accounting for the purchase contracts maturing in 2006 and 2007, as described above. We record the revenue associated with our mark-to-market contracts on a
net basis in purchased power expense in our condensed consolidated statements of income.



The following table summarizes the derivative assets and liabilities for the energy contracts included in the condensed consolidated balance sheets for both Holdings and Duquesne Light:

---

The change in the net derivative assets, for contracts not accounted for as cash flow hedges, of
$22.8 million for the nine months ended September 30, 2005, has been recorded as an offset to purchased power expense in the condensed consolidated statements of income for both Holdings and Duquesne Light. For the nine months ended
September 30, 2005, the amount related to hedge ineffectiveness of energy contracts was immaterial.



Interest Rate Locks



In anticipation of the August 2005 issuance of $320 million of senior unsecured debt, Holdings entered into a series of interest rate lock agreements
during the second quarter of 2005 to hedge exposure to interest rate fluctuations for $250 million of the senior unsecured debt. These agreements were designated as cash flow hedges under SFAS No. 133. Holdings settled the rate lock agreements
in conjunction with the issuance of the debt, therefore the hedge was determined to be 100% effective. As a result of the settlement, Holdings received $7.4 million in cash and recorded $4.3 million in the statement of comprehensive income, net of
deferred taxes of $3.1 million. Amounts recorded in comprehensive income related to these agreements will be recognized as an approximate $0.3 million reduction of annual interest expense through August 2015, and an approximate $0.2 million annual
reduction from September 2015 through August 2035.



On
February 9, 2005, we entered into an interest-rate lock agreement for $100 million of senior unsecured debt that we originally planned to issue in the first quarter of 2005. The interest-rate lock was designated as a cash flow hedge under SFAS
No. 133. Changes in our cash requirements resulted in the postponement of the debt offering. On March 30, 2005, we unwound the interest-rate lock agreement, resulting in a $4.0 million pre-tax gain that was recorded in other income on
Holdings condensed consolidated statements of income.



5. DISPOSITIONS



In September 2005, DQE Financial sold its investment in a
leveraged lease involving a gas processing facility, received $9.9 million in cash and recorded a pre-tax loss of $1.3 million in other income on Holdings condensed consolidated statement of income.



In August 2005, DES entered into agreements to sell up to six on-site energy
facility management projects to DTE Energy Services for expected aggregate cash proceeds of between $35 and $40 million, subject to working capital adjustments. On September 30, 2005, DES closed on the sale of one of the energy facility
management projects, received $24.5 million in cash and recognized a pre-tax gain of $18 million in other income on Holdings condensed consolidated statement of income.



In the first nine months of 2005, DQE Financial received $2.5 million in additional cash sales proceeds related to the 2004
sale of 50% of its investment in a synthetic fuel partnership, and has recognized an additional pre-tax gain in other income on Holdings condensed consolidated statement of income. Additional sale proceeds may be received during the remainder of the
tax credit period through December 2007.



In January 2005, DQE
Financial sold its investment in a natural gas operating partnership for $12.7 million in cash and recognized a pre-tax gain of $7.1 million in other income on Holdings condensed consolidated statement of income.



In September 2004, DQE Financial sold an investment in a landfill gas
operation and received $2.9 million of cash proceeds, and recognized a pre-tax loss of $2.1 million in other income on Holdings condensed consolidated statement of income. In August 2005, DQE Financial determined that no additional proceeds are to
be received related to the contingent portion of the sale. Therefore, DQE Financial has recognized an additional pre-tax loss of $3 million in other income, on Holdings condensed consolidated statement of income, related to the basis in the assets
that were subject to the contingent portion of the sale.



In
September 2004, Duquesne Power terminated the acquisition of the Sunbury generation station and recorded an $8.3 million pre-tax charge related to the write-off of deferred costs and deposits made.



6. NOTES PAYABLE AND LONG-TERM DEBT



During August 2005, Holdings issued $200 million of 5.5% senior notes due
August 15, 2015 and $120 million of 6.25% senior notes due August 15, 2035. Proceeds were used to repay the $250 million intercompany loan with Duquesne Light and approximately $37 million of variable rate borrowings under Holdings
credit facility. The remaining balance was used for general corporate purposes.



Duquesne Light used the proceeds received from the repayment of the Holdings intercompany loan plus available cash to purchase at par upon mandatory tender $320.1 million of variable rate Pollution Control
Revenue Refunding Bonds with maturity dates ranging from 2020 to 2033. The purchased bonds are presented as extinguished debt



12



---

in conformity with SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets
and Extinguishments of Liabilities.



During July 2005,
both Holdings and Duquesne Light extended the maturity date of their existing revolving credit facilities from September 2007 to July 2010. In addition, Holdings credit facility was increased from $175 million to $200 million.



As of September 30, 2005, no borrowings were outstanding under either
the Holdings or Duquesne Light revolving credit facility. Letters of credit totaling $62.1 million at Holdings (including $6.7 million at Duquesne Light) were outstanding under the credit facilities on September 30, 2005.



In May 2004, Duquesne Light issued $200 million of 5.7% first mortgage bonds
(due 2014).



During 2004, Duquesne Capital redeemed
$150 million principal amount of its Monthly Income Preferred Securities, Series A (MIPS). Pursuant to the terms of the MIPS, Duquesne Light simultaneously redeemed $151.5 million of its Subordinated Debentures.



On February 18, 2004, as part of an amended and restated concession
agreement with the City of New York, GSF Energy, L.L.C., a DQE Financial subsidiary, paid $4.5 million to the City and was released from all financial obligations under the prior concession agreement, including the $21.4 million note
payable to the City. As a direct result of the settlement, we are recognizing approximately $16 million in pre-tax income ratably over the new contract term, scheduled to end June 30, 2006.



7. COMMITMENTS AND CONTINGENCIES



Guarantees



As part of DQE Financials investment portfolio in seven affordable housing funds, we have received fees in exchange
for guaranteeing a minimum defined yield to unrelated investors. We entered into these transactions between 1995 and 1999 because of the attractive risk/reward characteristics available to guarantors. The guarantee period will expire by 2015. In the
event the underlying affordable housing properties do not generate the necessary minimum yield during the guarantee period, we will make cash payments necessary to achieve the minimum yield. The original amount guaranteed was approximately $250
million, and has declined as investors have earned the guaranteed returns. We estimate the maximum potential amount of undiscounted future payments that we could be required to make under the guarantees if the investors earn no future returns was
$40.5 million as of September 30, 2005.



In connection
with the sale of six synthetic fuel facilities in 2000 by our indirect subsidiary, Duquesne Energy, Inc., we agreed to guarantee our subsidiarys obligations and liabilities to the third party purchaser under the purchase agreement, including
our subsidiarys indemnification obligations against breaches of warranties, representations and covenants contained therein. The guarantee generally extends up to six years or otherwise as provided under the applicable statute of limitations,
based on the expiration of the underlying representations, warranties and covenants. We have determined our exposure to be limited, as both legal and factual representations and warranties have been primarily limited to matters within the control
and knowledge of our subsidiary. As such, no liability has been recorded on the condensed consolidated balance sheets. In connection with an IRS audit for the years 1998 through 2002 described in this footnote below under the subheading Income
Taxes, in July 2005, the IRS issued a Notice of Proposed Adjustment in which its field auditors asserted that five of the six synthetic fuel facilities sold in 2000 were not placed in service by the required June 30, 1998 date and,
therefore, the Section 29 tax credits for those five facilities should be disallowed.



We do not agree with the IRS position and will vigorously defend our position that the synthetic fuel facilities were placed in service by June 30, 1998.



In addition, Holdings has backed certain limited obligations during a
long-term contract held by a subsidiary with a $1.5 million payment guarantee that has not been recorded as a liability on the condensed consolidated balance sheets. We do not believe these guarantees will have any material impact on our results of
operations, financial position or cash flows.



Holdings has
guaranteed portions of the obligations of Duquesne Power under its energy commodity contracts in order to use Holdings stronger credit profile to obtain better pricing and contract terms for Duquesne Power. In general, if Duquesne Power is
required to make a payment under these contracts and fails to do so, Holdings would be required to make such payment. The notional value of the contracts (and consequently the guarantee amounts) changes as additional energy commodities are bought or
sold, and as Duquesne Power pays for its energy commodity deliveries. As of September 30, 2005, the maximum amount of Holdings payment guarantee related to the purchase and capacity obligations totaled $687.7 million, or 85%, of the total
remaining notional value under these contracts. In addition, Holdings guarantees Duquesne Powers obligations to deliver energy



13



---

under the energy sales contracts, to the extent that Duquesne Power would be obligated to compensate the counterparty for
the difference in the counterpartys cost to procure the energy and the contract price. As of September 30, 2005, no guarantee amount has been recorded as a liability on the condensed consolidated balance sheets. In addition, Holdings
posts collateral on behalf of Duquesne Power as needed under the energy commodity contracts. As of September 30, 2005, no collateral was outstanding.



In conjunction with certain transactions, primarily divestitures, we provide routine indemnifications (e.g., retention of previously existing
environmental, tax and employee liabilities) whose terms range in duration and often are not explicitly defined. Where appropriate, an obligation for such indemnifications is recorded as a liability. Because the obligated amounts of these types of
indemnifications often are not explicitly stated, the overall maximum amount of the obligation under such indemnifications cannot be reasonably estimated. Other than obligations recorded as liabilities at the time of divestiture, historically we
have not made significant payments for these indemnifications.



Income Taxes



The IRS has audited all federal corporate tax returns for
the years through 1997 and these years are closed. As a result of this audit, the balance, including interest due to the IRS, of $52.9 million and $50.9 million as of September 30, 2005 and December 31, 2004, is included in other current
liabilities on our condensed consolidated balance sheets.



The
IRS is currently auditing the 1998 through 2002 tax years. During that period, one of our subsidiaries constructed and operated six synthetic fuel facilities, which were subsequently sold in the year 2000 to a third party, as described more fully in
this footnote above under the subheading Guarantees. DES currently operates five of these six facilities under an agreement with the third party purchaser. In July 2005, the IRS issued a Notice of Proposed Adjustment in which it
determined that five of these six facilities were not placed in service by the required June 30, 1998 date and, therefore, the Section 29 tax credits for these five facilities should be disallowed. As discussed above, we do not agree with
the IRS position. We cannot predict when this issue will ultimately be resolved. We claimed approximately $6.5 million of Section 29 tax credits relating to the ownership of these five synthetic fuel facilities prior to their sale in
2000.



The Pennsylvania Department of Revenue has issued
assessments of additional tax for 1999 through 2002 primarily to include income of a Duquesne Light out of state subsidiary corporation in Pennsylvania taxable income. If, as expected, the Department asserts the same positions for 2003 and 2004,
Duquesne Lights total exposure for all years, without interest or penalty, could approximate $96 million (net of associated federal benefit). Ultimately, Duquesne Light expects all years involved to be appealed to and decided at the
Pennsylvania Commonwealth Court.



It is not possible to predict
if, when, or to what extent any state income tax adjustments ultimately proposed for the period 1999 through 2004 will be sustained. Duquesne Light does not believe that the ultimate resolution of its state tax issue for the years 1999 through 2004
will have a material adverse effect on its financial position or results of operation. However, the resolution, depending on the extent and timing thereof, could have a material adverse effect on cash flows for the period in which they are paid.



In connection with the above examinations, both Holdings and
Duquesne Light have established tax reserves, which are included in other current and non-current liabilities on the condensed consolidated balance sheets. We believe these reserves are adequate in relation to the above matters. We regularly assess
the likelihood of additional assessments resulting from these and subsequent years examinations. Once established, reserves are adjusted only when there is more information available or when an event occurs that necessitates a change to the
reserves.



Employees



Duquesne Light is a party to a labor contract with the International
Brotherhood of Electrical Workers, which represents more than 70% of Duquesne Lights approximately 1,400 employees. This contract was recently renegotiated, and expires in September 2010.



Legal Proceedings



Shareholder Class Action. In October 2005, the court approved a settlement of all claims of the class and sub-class.
The settlement will be covered in full by our insurance.



Possible Phase-out
of Section 29 Tax Credits



Section 29 of the
Internal Revenue Code provides tax credits through 2007 for the production and sale of non-conventional fuels, including solid synthetic fuels and landfill gas. Holdings earns Section 29 tax credits from DQE Financials landfill gas
operations

and an investment in a synthetic fuel partnership. Duquesne Energy Solutions operates synthetic fuel facilities for a
single customer, earning fees based on production.



Section 29 tax credits are subject to a phase-out provision that reduces tax credits as the average annual wellhead price per barrel of domestic crude oil increases into an inflation-adjusted phase-out range. For 2004, the tax credit
would have begun to phase-out if the annual average wellhead price of domestic crude oil exceeded $51.35 per barrel and would have been completely phased out if the annual average wellhead price of domestic crude oil exceeded $64.47 per barrel.



The 2005 phase-out range will be calculated using inflation
rates published in 2006 by the IRS. Based on both the estimated average wellhead price to date and current futures prices for the remaining months of 2005, we believe that there will not be a phase-out of tax credits in 2005.



Absent any efforts to mitigate market price exposure, if domestic crude oil
prices increase further in 2005 and continue to stay at a high level in 2006 and/or 2007, tax credits and net income may be reduced substantially due to the phase-out. Based on our evaluation, as of September 30, 2005, we have thus far
determined not to enter into hedging arrangements to reduce this exposure.



During the first nine months of 2005, we recorded $15.2 million of Section 29 tax credits on Holdings condensed consolidated statement of income. In addition, as of September 30, 2005, we have certain
tangible and intangible assets related to DQE Financials landfill gas operations with a net book value of approximately $6 million that may become impaired if domestic crude oil prices continue to increase in the future. As of
September 30, 2005, we have no net book value related to synthetic fuel assets or investments.



Discontinued Operations



As part of the sale of AquaSource, we retained certain obligations related to the business that was sold to Aqua America, Inc., including responsibility for certain existing litigation matters as well as a 10-year indemnity for certain
pre-closing environmental claims. We purchased an environmental liability policy to mitigate this indemnity. We also had a maximum three-year indemnity obligation for certain other pre-closing liabilities that was originally limited by a
$15 million indemnity cap. Because Aqua America had not made the minimum required threshold of indemnification requests during the first year after closing, this indemnity obligation was reduced to a $7.5 million cap over a two year period. We
have notified Aqua America that with the passage of the second anniversary of the closing of the transaction, the indemnification has terminated, and no further claims can be made under the indemnity obligation. Based on the closing of the
indemnification period and information relating to indemnification requests made to date, it does not appear that our ultimate liability to Aqua America under the indemnity obligation will have a material impact on Holdings earnings or cash
flow.



8. DISCONTINUED OPERATIONS



Pursuant to agreements entered into in 2002 to sell the majority of our
investment in AquaSource and our investment in Pro Am, as well as our subsequent sale of the remaining net assets of AquaSource, these subsidiaries have been reflected as discontinued operations in the condensed consolidated financial statements.



The $3.3 million promissory note, due April 1, 2005, from
former members of AquaSource management from the sale of AquaSources water and wastewater utility construction business was paid in full in January 2005 when the corresponding value of outstanding shares of Holdings common stock were
surrendered by these individuals.



In March 2005, we received
$0.9 million in cash as final settlement on the sale of Pro Am.

13. SUBSEQUENT EVENTS



On October 18, 2005, Holdings filed a shelf
registration statement for up to $400 million of preferred stock, common stock, stock purchase contracts, stock purchase units, warrants and debt securities, to be issued from time to time.



On October 31, 2005, DES closed on the sale of two energy facility
management projects, pursuant to the agreements entered into in August 2005, for $10.1 million in cash and the assumption by the buyer of certain non-cash lease related liabilities. As a result, DES will record a pre-tax gain of approximately
$13 million in October. The agreement for one of the above energy facility management



21



---

contracts provides the buyer with a guarantee that DES would repay a portion of the purchase price if the counterparty to
the management contract would terminate the contract for convenience, as defined by the agreement (the Repayment Guarantee). The maximum Repayment Guarantee amount is approximately $3.7 million if the contract is terminated immediately. The
Repayment Guarantee is reduced daily, based on the passage of time, through January 1, 2016, at which time the Repayment Guarantee expires. The estimated recorded liability for the fair value of the Repayment Guarantee is not material.



On October 31, 2005, DES agreed to terminate the
agreement to sell one of the six energy facility management projects entered into in August 2005. The termination of this agreement does not materially change the total expected proceeds resulting from these sales. (See Note 5.)



Item 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.



Part I, Item 2 of this combined
Quarterly Report on Form 10-Q should be read in conjunction with our combined Annual Report on Form 10-K for the year ended December 31, 2004 filed with the Securities and Exchange Commission (SEC), and with the condensed consolidated
financial statements, set forth in Part I, Item 1 of this Report.



This combined Quarterly Report on Form 10-Q presents information on both Duquesne Light Holdings, Inc. (Holdings) and Duquesne Light Company (Duquesne Light).



References in this report to we, us and
our are to Holdings and its subsidiaries, collectively. References to Notes are to the notes to the condensed consolidated financial statements, set forth in Part I, Item 1 of this report.



Holdings is an energy services holding company formed in 1989 to serve as the
holding company for Duquesne Light and to engage in unregulated energy and related businesses.



Duquesne Light, our largest subsidiary, was formed in 1912 by the consolidation and merger of three constituent companies. Duquesne Light is an electric utility engaged in the supply (through its
provider-of-last-resort service (POLR)), transmission and distribution of electric energy.



Duquesne Power, L.P., an unregulated subsidiary, maintains a portfolio of energy commodity contracts to provide full-requirements energy supply contracts for both (i) Duquesne Lights residential and small
commercial POLR customers and (ii) Duquesne Light Energy, LLCs large commercial and industrial customers. These energy commodity contracts are with unrelated parties and include payment guarantees from Holdings.



Duquesne Light Energy, LLC (DLE) is an unregulated, competitive, retail
electric generation supplier that offers customized solutions tailored to meet its customers specific electricity needs. DLEs primary focus is on the large commercial and industrial customer market segment in Duquesne Lights
service territory.



Duquesne Energy Solutions, LLC (DES) is an
energy facilities management company that provides energy outsourcing solutions including operation and maintenance of energy and synthetic fuel facilities.



DQE Financial Corp. owns, operates and maintains landfill gas collection and processing systems, and is an investment and portfolio management
organization focused on structured finance and alternative energy investments. Effective November 2004, DQE Financial became the sole owner of Waste Energy Technology, LLC (WET), a landfill gas engineering, design, construction and operations firm.



DQE Communications, Inc. owns, operates and maintains a
high-speed, fiber optic based metropolitan network, and leases dark fiber from the network to commercial, industrial and academic customers.



DQE Capital Corporation provides financing to Holdings for use with its affiliates.



Service Areas and Customer Concentrations



Duquesne Lights electric utility operations provide service to approximately 587,000 direct customers in southwestern Pennsylvania (including in
the City of Pittsburgh), a territory of approximately 800 square miles.



Our other business lines have operations and investments in several states and Canada. Duquesne Energy Solutions relies on a single customer, that owns several synthetic fuel facilities, for substantially all of its revenues and earnings.



Section 29 Tax Credits



In connection with the sale of six synthetic fuel facilities in 2000 by our
indirect subsidiary, Duquesne Energy, Inc., we agreed to guarantee our subsidiarys obligations and liabilities to the third party purchaser under the purchase agreement, including our subsidiarys indemnification obligations against



22



---

breaches of warranties, representations and covenants contained therein. The guarantee generally extends up to six years
or otherwise as provided under the applicable statute of limitations, based on the expiration of the underlying representations, warranties and covenants. We have determined our exposure to be limited, as both legal and factual representations and
warranties have been primarily limited to matters within the control and knowledge of our subsidiary. As such, no liability has been recorded on the condensed consolidated balance sheets. In connection with an Internal Revenue Service (IRS) audit
for the years 1998 through 2002, in July 2005, the IRS issued a Notice of Proposed Adjustment in which its field auditors asserted that five of the six synthetic fuel facilities sold in 2000 were not placed in service by the required June 30,
1998 date and, therefore, the Section 29 tax credits for these five facilities should be disallowed for the current owner and us.



DES currently operates five of these six facilities under an agreement with the third party owner. The third party owner claims Section 29 tax
credits with regard to the production of the synthetic fuel. We previously claimed approximately $6.5 million of Section 29 tax credits relating to the ownership of these five synthetic fuel facilities prior to their sale in 2000. Both the
third party owner and we disagree with the IRS position. We will vigorously defend our position that the synthetic fuel facilities were properly placed in service by June 30, 1998. We are currently considering resolution of this matter by
seeking technical advice from the IRS National Office, pursuing an administrative appeal and/or litigating the matter. We believe that the tax credits for the years we owned the facilities, as well as for all of the years the current owner is
otherwise eligible to claim the credits, will eventually be allowed. This belief is based on our understanding of the relevant facts, and our understanding that another taxpayer recently announced that it received from the IRS National Office a
favorable technical advice memorandum regarding the placed in service date of its synthetic fuel facilities after disputing this issue with the field agents auditing its tax returns. We cannot predict the timing or the nature of the ultimate outcome
of this process. It could take a number of years before it is ultimately resolved. In the meantime, we continue to operate all of these facilities for the owner.



Should the third party owner reduce or terminate operation of the synthetic fuel facilities for whatever reason, our
earnings and revenues from operating and maintaining the facilities would also be reduced or terminated.



Regulation



Holdings
and Duquesne Light are subject to the accounting and reporting requirements of the SEC. Duquesne Lights electricity delivery business is also subject to regulation by the Pennsylvania Public Utility Commission (PUC) and the Federal Energy
Regulatory Commission (FERC) with respect to rates for delivery of electric power, accounting and other matters.



Business Segments



This information is set forth in Results of Operations below and in Note 12 to our condensed consolidated financial statements.



Critical Accounting Policies



As of September 30, 2005, there have been no significant changes with
regard to the critical accounting policies disclosed in Managements Discussion and Analysis in our Annual Report on Form 10-K for the year ended December 31, 2004 except as discussed below. The policies disclosed included the accounting
for the following: the effects of regulation, unbilled electricity revenues, impairment of long-lived assets and investments, pension and other postretirement benefit plan assumptions, income taxes, derivative instruments and contingent liabilities.



We have expanded our policy concerning derivative instruments
to include the accounting for revenue associated with the settlement of our mark-to-market energy contracts and for derivative instruments that qualify for hedge accounting.



Beginning January 1, 2005, we record the revenue associated with our mark-to-market contracts on a net basis in
purchased power expense in our condensed consolidated statements of income in accordance with the Emerging Issues Task Force No. 99-19 Reporting Revenue Gross as a Principal versus Net as an Agent.



When a derivative instrument is entered into management also determines if
the derivative qualifies as either a cash flow hedge (a hedge of variable cash flows of a single transaction or a group of similar transactions) or as a fair value hedge (a hedge of the fair value of specific assets and liabilities or specific firm
commitments), in accordance with Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended and interpreted. This process includes formally documenting
(i) the hedging relationships and its risk-management objective and strategy for undertaking the hedge transactions, (ii) the hedging



23



---

instrument, (iii) the hedged item or transaction, (iv) the nature of the risk being hedged, (v) how the
hedging instruments effectiveness in offsetting the hedged risk will be assessed, and (vi) a description of the method of measuring ineffectiveness. Management also formally assesses, both at the hedges inception and on an ongoing
basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows or fair values of hedged items.



Changes in the fair value of a derivative designated as a cash flow hedge that is determined to be highly effective are recorded in the statement of
comprehensive income, net of tax, and are recognized in earnings over the life of the hedged item. The ineffective portion of the change in fair value of a derivative instrument that qualifies as a cash flow hedge is recognized currently in
earnings. Changes in the fair value of a derivative designated as a fair value hedge that is determined to be highly effective, along with the corresponding gain or loss on the hedged item, are recognized currently in earnings.



When it is determined that a derivative has ceased to be a highly effective
hedge, hedge accounting is discontinued prospectively. When hedge accounting is discontinued for cash flow hedges, the derivative asset or liability remains on the condensed consolidated balance sheet at its fair value, and gains and losses that
were in accumulated other comprehensive income are recognized in earnings. When hedge accounting is discontinued for fair value hedges, the derivative asset or liability remains on the condensed consolidated balance sheet at its fair value and the
hedged asset or liability is no longer adjusted for changes in its fair value.



Proposed Accounting Standards



In July 2005
the Financial Accounting Standards Board (FASB) issued proposed FASB Staff Position No. 13-a Accounting for a Change or Projected Change in the Timing of Cash Flows Relating to Income Taxes Generated by a Leveraged Lease Transaction
(FSP No. 13-a). The proposed changes included in FSP No. 13-a are not yet in effect, but if issued in their current form, would be effective as of the end of the first fiscal year ending after December 15, 2005. As the December
2003 settlement with the IRS regarding DQE Financials structured lease and other similar investments modified our tax benefits under these leases, this proposed staff position, if issued in its current form, would apply to Holdings and be
effective as of December 31, 2005. This proposed staff position requires recognition of the modified tax benefits from the inception of the leases, and as a result, upon adoption of this standard, Holdings would record an after-tax, cumulative
effect charge of approximately $90 to $95 million as of December 31, 2005. We previously disclosed that the earnings volatility of the lease investments was removed as a result of the settlement with the IRS, and the revised earnings of $3
million to $4 million annually would be realized over the remaining lives of these leases. After adopting this staff position, the amount of the cumulative effect charge initially recorded would be recognized as additional lease earnings, beginning
in 2006, over the remaining lives of these leases, which range from 22 to 31 years (with early buy-out periods ranging from 7 to 18 years). Our current and future cash flows would be unaffected by the adoption of this proposed FASB Staff Position.



In July 2005 the FASB issued an exposure draft of a proposed
interpretation of FASB Statement No. 109 Accounting for Uncertain Tax Positions. The proposed changes are not yet in effect, but are expected to be issued in the first quarter of 2006. We currently have certain tax disputes and are
under audit by both the Commonwealth of Pennsylvania and the IRS, as outlined in Note 7 to the condensed consolidated financial statements. This proposed interpretation, if issued in its current form, would apply to both Holdings and Duquesne Light
and would require recognition of a cumulative effect upon adoption. We are currently evaluating the overall impact of this proposed interpretation on both Holdings and Duquesne Lights financial statements.

RESULTS OF OPERATIONS



Duquesne Light reports the following business segments: (1) transmission and distribution of electricity (electricity delivery business segment),
(2) supply of electricity by Duquesne Light (Duquesne Light supply business segment), and (3) collection of transition costs (CTC business segment).



Holdings reports the following business segments: (1) transmission and distribution of electricity (electricity delivery business segment),
(2) supply of electricity (which includes the Duquesne Light supply business segment and beginning in 2005, supply by DLE) (electricity supply business segment), (3) collection of transition costs (CTC business segment), (4) DES
development, operation and maintenance of energy and, for a single customer, synthetic fuel facilities (Energy Solutions business segment), (5) DQE Financials collection and processing of landfill gas and management of structured finance
and alternative energy investments (Financial business segment), and (6) DQE Communications operation, maintenance and leasing of its fiber optic based network (Communications business segment). We also report an all other
category which includes our other subsidiaries that are below the quantitative threshold for disclosure. These subsidiaries provide corporate administrative functions, financing, and insurance services for our various affiliates.



Note 12 to the condensed consolidated financial statements shows the
financial results of each principal business segment in tabular form. Following is a discussion of these results. Unless otherwise stated, the terms earnings and loss used in the following discussion refer to after-tax
amounts.



Significant Changes in the Supply Business



The factors impacting the Duquesne Light supply business segment have
significantly changed when compared to prior periods. From the time that Duquesne Light sold its generation assets in April 2000 through December 31, 2004, the default energy supply requirement for all customers had been met through a full
requirements contract with one supplier. From the time that Duquesne Light completed its stranded cost recovery  different by each rate class, but generally during the 2002 to 2003 time period  Duquesne Light had earned a margin on each
megawatt-hour (MWh) supplied.



25



---

Effective January 1, 2005, residential and small commercial customers remaining on POLR service saw
an average increase of 11.5% above their POLR II generation rates, reflecting the increase in market energy prices in the time since the POLR II rates were established. Despite this increase in rates, residential and small commercial customer
retention has increased to 74% in the first nine months of 2005 compared to 73% in the first nine months of 2004.



Also effective January 1, 2005, Duquesne Light is meeting its POLR III energy supply requirements for residential and small commercial customers
through Duquesne Powers portfolio of energy and capacity supply contracts with multiple investment-grade counter-parties as well as through interactions with PJM Interconnection (PJM). This change in energy supply strategy is designed to
provide the opportunity to earn a larger margin in the supply business. While taking on increased commodity price risk, we have decreased our supplier credit/default risk. The increased commodity price risk has been managed at a prudent level
through the portfolio of energy commodity contracts. Because some of these contracts are not settled at the Duquesne Light zone, they are accounted for on a mark-to-market basis, with changes in the fair value of these contracts recorded currently
in earnings in 2005 unless certain hedge accounting criteria are met. To the extent the hedges are determined to be effective, the changes in the value of these contracts are included in the statement of comprehensive income, net of deferred taxes.
Amounts recorded in the statement of comprehensive income related to cash flow hedges will be recognized in earnings as the related contracts are settled.



While previously Duquesne Lights margin on residential and small commercial customers was a fixed dollar amount per MWh, beginning in 2005 the
earnings have an element of seasonality. Revenues per MWh, while fixed on an annual basis through 2007, are lowest in the first and fourth quarters reflecting the discount rate offered to electric heating customers in the November through April
heating season. The revenues per MWh are then higher in the remaining months. Similarly, costs per MWh are expected to have a seasonal element, being higher in the first and third quarters reflecting the peak energy consumption in the heating and
cooling seasons. As a result, margins on residential and small commercial customer energy supply are anticipated to be higher in the second and fourth quarters.



For large business customers, effective January 1, 2005, the POLR energy supply product is a fluctuating hourly-priced service. Additionally, for
a limited time, Duquesne Light offers a fixed-price service whose rate has increased by an average of more than 20% reflecting the results of a competitive wholesale request-for-proposal conducted in the fall of 2004. Duquesne Light continues to
meet its POLR energy supply requirement for large customers through interactions with PJM and with full requirements contracts, now with two investment-grade suppliers. Because of the volatility of hourly-priced POLR service and the increase in the
fixed-price rates, POLR retention for large commercial and industrial customers has decreased from 60% in the first nine months of 2004 to 22% in the first nine months of 2005. It is anticipated that the POLR retention rate will continue to decline
throughout 2005.



Under the POLR II arrangement that ended
December 31, 2004, Duquesne Light earned a margin on each MWh sold to its large commercial and industrial customers. During the three and nine months ended September 30, 2004, Duquesne Light earned net income of $1.1 million and
$3.6 million in the supply business related to sales to its large commercial and industrial customers. Under the POLR III arrangement that became effective January 1, 2005, Duquesne Light no longer earns a margin in the supply
business on these sales.



In response to the change in large
customer POLR service, DLE has begun to offer competitive electric generation (EGS) service to customers in the Duquesne Light service territory. The DLE supply requirements are managed together with the Duquesne Light residential and small
commercial customer POLR III supply requirements by Duquesne Power.



Overall
Performance



Three months ended September 30,
2005. Our net income was $43.6 million, or $0.56 basic earnings per share in the third quarter of 2005, compared to $23.6 million, or $0.31 basic earnings per share, in the third quarter of 2004. The average shares outstanding increased
1.2 million, or 1.6%, compared to 2004.



Our income from
continuing operations was $43.5 million, or $0.56 basic earnings per share, in the third quarter of 2005, compared to $23.4 million, or $0.31 basic earnings per share, in the third quarter of 2004. The increase of $20.1 million is primarily due
to an $11.7 million after-tax gain recorded in the Energy Solutions business segment related to the sale of an equity investment in an energy facility operating partnership during the third quarter of 2005, and a $10.3 million increase in earnings
at Duquesne Light, discussed below.



26



---

Duquesne Lights earnings available for common stock were $25.3 million in the third quarter of
2005, compared to $15.0 million in the third quarter of 2004, an increase of $10.3 million, or 68.7%. This was primarily due to a $9.5 million increase in earnings from Duquesne Lights electricity supply business segment. This increase
includes a $6.5 million after-tax increase in earnings as a result of an increase in the fair value of the mark-to-market energy contracts since June 30, 2005 and a $4.8 million after-tax charge related to the termination of the acquisition of
the Sunbury generation station that was included in the third quarter of 2004 results. These increases were partially offset by a $1.8 million decrease in earnings primarily due to the fact that Duquesne Light earns no margin on sales to large
commercial and industrial customers under the POLR III arrangement.



Nine months ended September 30, 2005. Our net income was $100.1 million, or $1.29 basic earnings per share in the first nine months of 2005, compared to $68.8 million, or $0.90 basic earnings per share, in the first nine
months of 2004. The average shares outstanding increased 1.3 million, or 1.7%, compared to 2004.



Our income from continuing operations was $99.7 million, or $1.28 basic earnings per share, in the first nine months of 2005, compared to $68.1
million, or $0.89 basic earnings per share, in the first nine months of 2004. The increase of $31.6 million is primarily due to the $11.7 million after-tax gain recorded in the Energy Solutions business segment discussed above, a $9.3 million
increase in earnings at Duquesne Light, discussed below, the elimination of $3.7 million of after-tax interest costs at DQE Capital Corporation related to the long-term debt redeemed in the fourth quarter of 2004, and a $3.1 million increase in
earnings from operations related to pipeline quality landfill gas. These increases were partially offset by $1.4 million of additional after-tax interest costs related to the issuance of $320 million of senior unsecured notes at Holdings in August
2005.



Duquesne Lights earnings available for common
stock were $57.8 million in the first nine months of 2005, compared to $48.5 million in the first nine months of 2004, an increase of $9.3 million, or 19.2%. The increase was primarily due to a $17 million increase in earnings from Duquesne
Lights supply business segment, primarily as a result of a $13.1 million after-tax increase in the fair value of the mark-to-market energy contracts at Duquesne Power since December 31, 2004, and the $4.8 million after-tax charge included
in the 2004 results, discussed above. These increases were partially offset by a $7.7 million decrease in earnings from the electricity delivery business segment, primarily as a result of increases in operating expenses, interest expense and
preferred dividends, as compared to the first nine months of 2004.



Business
Segment Performance



Electricity Delivery Business Segment



Three months ended September 30, 2005. This
segment reported earnings of $16.3 million in the third quarter of 2005, compared to $15.5 million in the third quarter of 2004, an increase of $0.8 million, or 5.2%. This increase was the result of increased revenues more than offsetting
higher operating expenses.



Operating revenues are primarily
derived from the delivery of electricity, and include related excise taxes. Sales to residential and commercial customers are primarily influenced by weather conditions. Warmer summer and colder winter seasons generally lead to increased customer
use of electricity for cooling and heating. Commercial sales also are affected by regional development. Sales to industrial customers are influenced by national and global economic conditions.



The following table sets forth the MWh delivered to electric utility
customers.

Operating revenues
increased $4.9 million, or 5.3%, compared to the third quarter of 2004. The increase was primarily due to increased MWh sales to residential and commercial customers as a result of the relatively hot weather that occurred in 2005 compared to 2004.
These increased sales were more than sufficient to offset a decline in MWh sales to and revenue from the industrial sector, as well as the loss of ancillary services revenue in 2005 as this revenue is now being reported in the Duquesne Light supply
business segment as a result of the POLR III arrangement.



Operating expenses consist primarily of costs to operate and maintain the transmission and distribution system; meter reading, billing and collection costs; customer service; administrative

expenses; and non-income taxes, such as gross receipts, property and payroll taxes Operating expenses increased $3.1
million, or 7.6%, compared to the third quarter of 2004. Due to increased participation in the customer assistance program, collection costs increased $2.2 million compared to the third quarter of 2004. In addition, approximately $0.8 million of
regulatory related expenses were incurred in the third quarter of 2005 related to preparation work for the upcoming distribution and transmission rate cases. Other cost increases are primarily due to the acceleration of the timing of certain
maintenance projects in anticipation of significant capital expenditures to be done in the fourth quarter of 2005. Ancillary services expense decreased $2.1 million in the third quarter of 2005, due to the majority of this cost now being reported in
the Duquesne Light supply segment as a result of the POLR III arrangement.



Nine months ended September 30, 2005.This segment reported earnings of $31.1 million in the first nine months of 2005, compared to $38.8 million in the first nine months of 2004, a decrease of $7.7
million, or 19.8%. The decrease was primarily the result of increases in operating expenses, interest expense and preferred dividends.



The following table sets forth the MWh delivered to electric utility customers.

Operating expenses
increased $8.3 million, or 6.7%, compared to the first nine months of 2004. As a result of the increased focus on Duquesne Light following the sale of several of Holdings non-complementary businesses, there are approximately $4.3 million of
additional costs that were borne by this segment in the first nine months of 2005 compared to the prior year. Due to increased participation in the customer assistance program, collection costs increased $3.5 million compared to the first nine
months of 2004. In addition, approximately $1.8 million of regulatory related expenses have been incurred in 2005 related to the filing for recovery of SECA charges and preparation work for the upcoming distribution and transmission rate cases.
Other cost increases are primarily due to the acceleration of the timing of certain maintenance projects, as previously discussed. Ancillary services expense decreased $5.3 million in the first nine months of 2005, for the reason discussed above.



Interest and other charges increased $2.4 million, or 7.0%,
compared to the first nine months of 2004, primarily due to $4.3 million in additional interest on the $200 million of 5.7% debt issued in May 2004, and $2.3 million in additional interest expense resulting from higher interest rates in 2005 on
variable rate debt. These increases were partially offset by a $3.1 million reduction in interest due to the redemption of $151.5 million of subordinated debentures in the first six months of 2004.



Dividends on preferred and preference stock increased $1.4 million, or 30.4%,
compared to the first nine months of 2004 due to the $75 million of 6.5% preferred stock issued in April 2004.



Dividends on Duquesne Lights preferred stock are included in interest and other charges in the Holdings presentation of the Electricity Delivery
Business Segment.



Duquesne Light Supply Business Segment



Three months ended September 30, 2005. As previously discussed,
the factors impacting this segment in 2005 have significantly changed when compared to the prior year. The following table summarizes the earnings from this segment.

Under the POLR II
arrangement in 2004, the margin on sales to residential and small commercial customers was a fixed dollar amount per MWh supplied, while under the POLR III arrangement in 2005, the margin on these customers is no longer fixed. The $0.7 million
decrease in earnings from the residential and small commercial customers compared to the third quarter of 2004 reflects the higher POLR III rates as well as the seasonal effects on the costs to serve those customers. As previously

stated, costs per MWh under the POLR III arrangement are expected to have a seasonal element, and are expected to be
higher in the third quarter, reflecting peak energy consumption during the cooling season. Under the POLR II arrangement, Duquesne Light earned a margin per MWh on sales to large commercial and industrial customers, however there is no margin under
the POLR III arrangement associated with these customers, which accounts for a $1.1 million decrease in earnings from the third quarter of 2004. In addition, certain energy contracts entered into by Duquesne Power are accounted for on a
mark-to-market basis, with changes in the fair value of these contracts recorded currently in earnings in 2005. As shown above, the earnings from the Duquesne Light supply business segment were favorably impacted in the third quarter of 2005 by a
$6.5 million after-tax increase in the fair value of these energy contracts. In the third quarter of 2004, Duquesne Light recorded a $4.8 million after-tax charge related to the termination of the acquisition of the Sunbury generation station.



Operating revenues are derived primarily from the supply of
electricity to POLR retail customers. Retail energy requirements fluctuate as the number of customers choosing alternative generation suppliers changes. Energy requirements for residential and commercial customers are also influenced by weather
conditions; temperature extremes lead to changes in customer use of electricity for cooling and heating. Commercial energy requirements are also affected by regional economic development. Energy requirements for industrial customers are primarily
influenced by national and global economic conditions.



In
addition, operating revenues include, to a lesser extent, the supply of electricity to wholesale customers. Beginning in 2005, these sales are primarily comprised of sales to DLE by Duquesne Power under its full-requirements energy supply contract.
In 2004, these sales primarily consisted of short-term sales to other utilities that were made at market rates, and resulted primarily from excess daily energy deliveries to Duquesne Lights electricity delivery system.

Operating revenues
increased $9.6 million, or 8.2%, compared to the third quarter of 2004. Effective January 1, 2005, Duquesne Light began operating under the POLR III arrangement, which allows for a higher average generation rate to be charged to customers
compared to the POLR II arrangement. In addition, ancillary services revenue is now being reported in this segment, as previously discussed. These two items represent an approximate $25 million increase in operating revenues as compared to
the third quarter of 2004. There was also an approximate $12 million increase in wholesale sales of electricity in the third quarter of 2005, primarily due to sales to DLE. As expected, there has been a significant decrease in MWh supplied to large
commercial and industrial customers compared to 2004, as a higher percentage of these customers chose an alternative generation supplier in 2005. This resulted in an approximate $28 million decrease in operating revenues compared to the third
quarter of 2004.

In 2005, operating expenses consist of (i) costs to obtain energy and capacity for Duquesne
Lights POLR service and to supply DLE, (ii) changes in the market value of derivative energy commodity contracts, (iii) administrative expenses at Duquesne Power, and (iv) gross receipts tax. In 2004, operating expenses
consisted primarily of costs to obtain energy for our POLR service and gross receipts tax, both of which fluctuated directly with operating revenues.



Operating expenses increased $1.0 million, or 0.9%, compared to the third quarter of 2004. The cost for the energy supplied was approximately $10.5
million higher in the third quarter of 2005, but was offset by an increase in the fair value of the energy commodity contracts from June 30, 2005.



Nine months ended September 30, 2005. The following table summarizes the earnings from this segment.

The $2.7 million
increase in the earnings from the residential and small commercial customers from the first nine months of 2004 reflects the higher POLR III rates as well as the seasonal effects on the costs to serve those customers. As previously stated, costs per
MWh under the POLR III arrangement are expected to have a seasonal element, and are expected to be higher in the first and third quarters, reflecting the peak energy consumption in the heating and cooling seasons, and lower in the second quarter.
Under the POLR II arrangement, Duquesne Light earned a margin per MWh on sales to large commercial and industrial customers, however there is no margin under the POLR III arrangement associated with these customers, and this accounts for a $3.6
million decrease in earnings from the first nine months of 2004. In addition, some of the energy contracts entered into by Duquesne Power are accounted for on a mark-to-market basis, with changes in the fair value of these contracts recorded
currently in earnings in 2005. As shown above, the earnings from the Duquesne Light supply business segment were favorably impacted in the first nine months of 2005 by a $13.1 million after-tax increase in the fair value of these energy contracts
since December 31, 2004. The results for 2004 included the $4.8 million after-tax charge related to the termination of the Sunbury acquisition.

Operating revenues
increased $9.2 million, or 2.8%, compared to the first nine months of 2004. The combination of the higher average generation rate charged to customers under the POLR III arrangement, and the addition of the ancillary services revenue that is being
reported in this segment in 2005 caused an approximate $49 million increase in operating revenues in the first nine months of 2005 compared to the prior year. In addition, there was an approximate $26 million increase in wholesale sales of
electricity in the first

---

nine months of 2005, due primarily to sales to DLE. As shown in the tables above, there has been a significant decrease
in the MWh supplied to large commercial and industrial customers as a higher percentage of these customers chose an alternative generation supplier in 2005. This resulted in an approximate $66 million decrease in operating revenues as compared to
the first nine months of 2004.



Operating expenses decreased
$12.7 million, or 4.1%, compared to the first nine months of 2004, due primarily to the reduction in purchased power expense as a result of the increase in the fair value of the mark-to-market energy commodity contracts from December 31, 2004.
This decrease was partially offset by increased selling, general and administrative expenses as well as gross receipts tax in 2005.



Electricity Supply Business Segment



Three and nine months ended September 30, 2005.Earnings from this segment include the results of the Duquesne Light supply business segment
and, beginning January 1, 2005, the results of Holdings unregulated retail electric generation supplier, DLE. The revenues and energy and capacity costs relating to the full-requirements contract between Duquesne Power (which are included
in the Duquesne Light supply business segment) and DLE are eliminated and instead DLEs retail sales to its large commercial and industrial customers are presented. As a result, overall earnings and operating revenues and expenses of this
segment are substantially unchanged from corresponding amounts discussed in the Duquesne Light supply business segment above.



The following tables set forth the retail MWh supplied to the electricity supply business segment customers.

Energy Solutions Business Segment.



Three months ended September 30, 2005. This
segment reported income of $19.1 million in the second quarter of 2005, compared to $6.9 million in the second quarter of 2004, an increase of $12.2 million, or 176.8%. The increase is primarily due to an $11.7 million after-tax gain
related to the sale of our equity investment in an energy facility operating partnership.



Operating revenues are derived primarily from the facility management services for synthetic fuel, industrial, and manufacturing customers. Operating revenues for the third quarter of 2005 increased $1.3 million,
or 6.4%, compared to 2004 as a result of increased revenues from both the synthetic fuel and energy facility contracts in the third quarter of 2005.



Other income consisted of income from an equity investment in an energy facility operating partnership until its sale in the third quarter of 2005, and
various other gains and losses. Other income increased $18.3 million from the third quarter of 2004 primarily as a result of an $18 million pre-tax gain on the sale of our equity investment previously discussed.



Nine months ended September 30, 2005. This segment reported
income of $29.5 million in the first nine months of 2005, compared to $16.2 million in the first nine months of 2004, an increase of $13.3 million, or 82.1%. The increase is primarily due to the $11.7 million after-tax gain previously discussed and
a $2.3 million increase in earnings from the synthetic fuel facilities management services contract.



Operating revenues for the first nine months of 2005 increased $3.7 million, or 7.4%, compared to 2004. The increase was primarily due to a
$2.6 million increase in revenues related to the synthetic fuel facilities as a result of an approximate 6% increase in synthetic fuel production in the first nine months of 2005.



Other income increased $17.6 million from the first nine months of 2004 primarily as a result of the $18 million pre-tax
gain previously discussed.

Financial Business Segment.



Three months ended September 30, 2005. This segment reported income of $4 million in the third quarter of 2005,
compared to $6 million in the third quarter of 2004, a decrease of $2 million, or 33.3%, primarily due to a net after-tax reduction in earnings of $2.6 million in the third quarter of 2005 relating to the divestitures of certain equity
investments. This decrease was partially offset by a $0.9 million increase in earnings from operations related to pipeline quality landfill gas.



Operating revenues are derived primarily from the sale of landfill gas and related services. Operating revenues for the third quarter of 2005 increased
$3.8 million, or 50.7%, compared to 2004. The increase is primarily the result of $1.9 million of revenues included in the results for the third quarter of 2005 related to the consolidation of WET as a result of our purchase of the remaining 50%
interest in the company in the fourth quarter of 2004. In addition, there was a $1.8 million increase in pipeline quality landfill gas sales in the third quarter of 2005, compared to the same period in 2004. This increase is a result of an
approximate 42% increase in the average price of pipeline quality landfill gas, which more than offset the approximate 7% decrease in volumes of pipeline quality landfill gas sold primarily as a result of planned outages that occurred in the third
quarter of 2005.



Operating expenses consist of various costs
to operate and maintain the landfill gas sites, as well as expenses related to alternative fuel investments. Operating expenses increased $2.2 million, or 20.6%, compared to the third quarter of 2004, primarily due to $1.6 million of net operating
expenses included in the results for the third quarter of 2005 related to the consolidation of WET.



Other income consists of income from the structured lease, affordable housing and equity investments, and various other gains and losses. Other income
decreased $1.9 million compared to the third quarter of 2004, primarily due a $1.3 million pre-tax loss from the sale of an investment in a leveraged lease transaction.



Income taxes consist of our provision for federal income taxes as well as the tax credits generated from our synthetic fuel
limited partnership, landfill gas and affordable housing investments. The income tax benefit for the third quarter of 2005 decreased $1.6 million, or 20.5%, compared to 2004 due to a $2 million decrease in tax credits generated in the third quarter
of 2005, primarily as a result of our sale of 50% of our investment in the synthetic fuel partnership in 2004.



Nine months ended September 30, 2005. This segment reported income of $22.8 million in the first nine months of 2005, compared to $19.7
million in the first nine months of 2004, an increase of $3.1 million, or 15.7%, primarily due to a $3.1 million increase in earnings from operations related to pipeline quality landfill gas.



Operating revenues for the first nine months of 2005 increased $10.1 million,
or 45.5%, compared to 2004. The increase is primarily the result of $6.3 million of revenue included in the results for the first nine months of 2005 related to the consolidation of WET. In addition, there was a $4 million increase in
pipeline quality landfill gas sales as a result of an approximate 22% increase in the average price of pipeline quality landfill gas sold in the first nine months of 2005, compared to the same period in 2004.



Operating expenses increased $3.4 million, or 10.9%, compared to the first
nine months of 2004, primarily due to $4.4 million of net operating expenses for the first nine months of 2005 related to the consolidation of WET.



Other income for the first nine months of 2005 increased $5.2 million, or 102%, compared to 2004, primarily due to the pre-tax gain of $7.1 million
related to the sale of the investment in a natural gas partnership. These increases were partially offset by a $2.4 million decrease in other income in the first nine months of 2005 due to the consolidation of the affordable housing investments as
described below.



The benefit from limited partners
interest reflects the portion of the losses related to the affordable housing guarantee funds that are not owned by the DQE Financial subsidiary as a result of the consolidation of the affordable housing investments effective March 31, 2004.



The income tax benefit for the first nine months of 2005
decreased $10.8 million, or 47.2%, compared to 2004, due to a $5.9 million decrease in tax credits generated in the first nine months of 2005, primarily due to the sale of 50% of our investment in the synthetic fuel partnership as previously
discussed, and the increase in pre-tax earnings in the first nine months of 2005 as compared to 2004.



Communications Business Segment.



Three and nine months ended September 30, 2005. This segment reported income of $0.7 million in the third quarter of 2005, compared to $0.6 million in the third quarter of 2004, an increase of $0.1
million, or 16.7%. This segment reported income of $1.9 million in the first nine months of 2005, compared to $1.3 million in the first nine months of 2004, an increase of $0.6 million, or 46.2%. The increases are primarily due to increases in
revenues from new and existing customers.

All Other.



Three months ended September 30, 2005. The all other category reported a loss of $5.6 million in the third quarter of 2005, compared to a loss
of $4.8 million in the third quarter of 2004, a decrease of $0.8 million, or 16.7%. The decrease is primarily due to an increase in operating expenses, due in large part to costs related to the current IRS audits.



Nine months ended September 30, 2005. The all other category
reported a loss of $11.9 million in the first nine months of 2005, compared to a loss of $17.3 million in the first nine months of 2004, an improvement of $5.4 million, or 31.2%. The improvement is primarily due to the elimination of $3.7 million of
after-tax interest costs related to the retirement of $100 million of debt in the fourth quarter of 2004 and a $2.4 million after-tax gain recorded at Holdings resulting from the favorable settlement of an interest rate lock arrangement in 2005.
These improvements were partially offset by $1.4 million of additional after-tax interest costs related to the issuance of $320 million of senior unsecured notes at Holdings in August 2005.



LIQUIDITY AND CAPITAL RESOURCES



Capital Expenditures



In the first nine months of 2005, Duquesne Light spent $73.9 million of capital expenditures for electric utility
construction. In addition, Holdings spent $2.8 million of capital expenditures relating to its other business lines and other investments. We estimate that during 2005, Duquesne Light will spend, excluding the allowance for funds used during
construction, approximately $150 million for electric utility construction related to its transmission and distribution infrastructure, and Holdings will spend approximately $5 million for construction by its other businesses.



Financing Plan



During August 2005, Holdings issued $200 million of 5.5% senior notes due August 15, 2015 and $120 million of 6.25%
senior notes due August 15, 2035. Proceeds were used to repay the $250 million intercompany loan with Duquesne Light and approximately $37 million of variable rate borrowings under Holdings credit facility. The remaining balance was used
for general corporate purposes.



Duquesne Light used the
proceeds received from the repayment of Holdings intercompany loan plus available cash to purchase at par upon mandatory tender $320.1 million of variable rate Pollution Control Revenue Refunding Bonds (PCRBs) with maturity dates ranging from
2020 to 2033. This purchase was in accordance with SFAS 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities, and is presented on Duquesne Lights balance sheet as an extinguishment of
debt, because Duquesne Light is the primary obligor of the PCRBs. Duquesne Light could remarket all of the PCRBs at future dates to refinance higher cost securities, fund infrastructure investments, and for general corporate purposes.



Duquesne Light has embarked on a significant infrastructure investment
program and plans to fund the program using equity infusions from Holdings and available cash. This financing plan originally included an equity issuance by Holdings of up to $150 million, however the ultimate amount of equity issued may be less,
depending on a number of factors, including available cash. We continue to explore other sources of funds for the infrastructure investment, including the potential divestiture of certain non-core assets. The timing of the equity issuance will
depend on the need for funds, and may occur as late as nine months after the distribution rate case is filed with the PUC, as discussed below in Rate Matters.



Liquidity



On October 18 2005, we filed a shelf registration statement for up to $400 million of preferred stock, common stock, stock purchase contracts, stock
purchase units, warrants and debt securities, to be issued from time to time. Our ability to issue such securities will depend on, among other things, market demand, interest rates, and corporate strategy.



During the first ten months of 2005, Holdings received cumulative cash
proceeds from dispositions of certain non-core assets totaling approximately $60 million. Holdings anticipates additional proceeds of approximately $5 million related to sales of two additional energy facility management projects that are expected
to close in the fourth quarter of 2005. Also in 2005, Holdings settled a series of interest rate lock agreements for cumulative cash proceeds of $11.4 million. These proceeds are to be used to fund capital expenditures and for general corporate
purposes.



In addition, during the first quarter of 2005,
Duquesne Light contributed $32.1 million to its pension plans, pursuant to a 2001 PUC order.

We believe that cash on hand, access to debt and equity capital markets, and bank borrowing capacity
continue to provide sufficient resources to fund our ongoing operating requirements, capital expenditures and estimated future infrastructure investments.



Available cash at all subsidiaries, including Duquesne Light, is deposited in the DQE Capital cash pool. Duquesne Lights investments in or
withdrawals from this cash pool are reflected as cash flows from investing activities on its condensed consolidated statements of cash flows.



Bank Credit Facilities. Prior to July 27, 2005 Holdings and Duquesne Light maintained unsecured credit facilities (Prior Revolvers) expiring
in September 2007, Holdings for $175 million and Duquesne Light for $100 million. On July 27, 2005 the Prior Revolvers were amended and extended to July 2010 (2005 Revolvers). Holdings 2005 Revolver is for $200 million and Duquesne Lights
2005 Revolver is for $100 million. Both 2005 Revolvers permit borrowings at interest rates of LIBOR (plus a margin of 0.40% to 1.00%) or an alternate base rate, as defined in the credit facilities. Both 2005 Revolvers have commitment fees applicable
to the remaining available amount. Interest rates and commitment fees are based on the borrowers then-current senior unsecured credit rating. Both 2005 Revolvers are subject to cross-default if the borrower or any of its subsidiaries defaults
on any payment due under any indebtedness exceeding $50 million. Undrawn amounts under both 2005 Revolvers are fully available for the issuance of letters of credit.



Under our Prior Revolvers and 2005 Revolvers, we are subject to financial covenants requiring each of Holdings and Duquesne
Light to maintain a debt-to-capitalization ratio of not more than 65%, as defined in the facilities. In addition, Holdings is required to maintain a minimum coverage ratio of 2-to-1, as defined in the facilities. As of September 30, 2005, we
were in compliance with the applicable covenants.



As of
September 30, 2005, our total borrowing capacity under our 2005 Revolvers and the use of this borrowing capacity were as follows:

During the first nine
months of 2005, the maximum amount of credit facility borrowings outstanding was $50 million (all at Holdings), the average daily borrowings were $6.1 million and the weighted average daily interest rate was 4.15%. As of September 30, 2005,
Holdings had $18.2 million of outstanding letters of credit (LOCs) (including $12.7 million at Duquesne Light) unrelated to the credit facilities.



OFF-BALANCE SHEET ARRANGEMENTS



Except for the guarantees discussed in Note 7, neither Holdings nor Duquesne Light has any material off-balance sheet arrangements. Neither Holdings
nor Duquesne Light is involved in any material contract trading activities.



RATE MATTERS



Seams Elimination Charge Adjustment



Effective January 1, 2005, Duquesne Light joined
PJM, becoming (along with other electric generation suppliers) a load-serving entity within PJM. In addition, POLR III became effective on that date.



As previously reported, the FERC has issued a series of orders eliminating the regional through and out rates (RTOR) for certain transmission services
between the Midwest Independent System Operator (MISO) and PJM effective December 1, 2004. A transitional pricing mechanism called the seams elimination charge adjustment (SECA) has been put in place through March 2006 in order to compensate
transmission owners for the estimated revenue lost as a result of the elimination of the RTOR. Total SECA charges for the Duquesne Light zone are expected to be approximately $39 million. The FERC has accepted revised compliance filings implementing
SECA charges among load-serving entities within the Duquesne Light zone. Under that filing, Duquesne Light was allocated approximately $11 million of the SECA charges. The other load-serving entities in the Duquesne Light zone were allocated the
remainder of such charges. DLEs allocation of SECA charges will depend on the amount of load it serves; based on current load, DLEs allocation is expected to be approximately $1.8 million.



The SECA charges must be paid by load-serving entities within the Duquesne
Light zone on a current basis. In June 2005, Duquesne Light filed a request with the PUC for permission to pass SECA charges through to its POLR customers. This request was granted, subject to disposition of any complaints filed



34



---

against the request, by the PUC in August 2005. Duquesne Light has put these charges into effect for service beginning
August 26, 2005. However, if the FERC ultimately adopts a SECA level and allocation method that differs from the proposed charges initially accepted by the FERC for billing purposes, refunds or surcharges will be used to compensate or charge
the appropriate entity for the difference between the amounts initially accepted by the FERC and the amounts ultimately determined to be just and reasonable by the FERC. The final amount of our SECA obligations therefore remains uncertain.



Distribution and Transmission Rate Cases



As a regulated utility, Duquesne Light may only change its distribution or
transmission rates by applying, through the rate case process, to the PUC or the FERC for approval. The goal of a rate case is to establish customer rates such that the utility (i) recovers its costs of providing the service, (ii) recovers
its costs of investing in the transmission and/or distribution infrastructure, and (iii) earns a reasonable and fair return on that investment. During a rate case, the utility must prove that its proposed rate increase is needed by showing its
costs during a given test year. The utilitys costs and expenditures are reviewed and challenged during this process. A rate case also considers a utilitys rate of return on its investment, as well as its costs of financing, in order to
derive its annual revenue requirement. The rates ultimately set are intended to give the utility a reasonable chance to achieve its revenue requirement.



Since customer choice was instituted in Pennsylvania in 1996, rate caps have prevented recovery of any new investment in transmission and distribution.
The last Duquesne Light rate case involving transmission and distribution costs dates back to 1987. Our transmission and distribution rate freeze expired at the end of 2003. We plan to file a distribution rate case with the PUC in the first half of
2006. The PUC has nine months from the date of the filing to render a final decision. We also plan to file a transmission rate case with the FERC later in 2006.



Item 3. Quantitative and Qualitative Disclosures About Market Risk.



Market risk represents the risk of financial loss that may impact our consolidated financial position, results of operations
or cash flows due to adverse changes in market prices and rates.



Both Holdings and Duquesne Light have potential market risk exposures to interest rate risk, commodity price risk and credit/default risk. Holdings also faces the potential risk of Section 29 tax credit phase-out. Holdings and Duquesne
Light have risk management procedures to monitor and assist in controlling these market risks and may use derivative and other instruments to manage some of these exposures.



Interest Rate Risk. Currently, neither Holdings nor Duquesne Light have any variable interest rate debt outstanding.
We manage our interest rate risk by retiring and issuing debt from time to time and by maintaining a range of maturity dates. A 10% reduction in interest rates would have increased the market value of fixed-rate debt by approximately
$36.1 million for Holdings and $27.6 million for Duquesne Light as of September 30, 2005. Such changes would not have had a significant near-term effect on our future earnings or cash flows.



In anticipation of the August 2005 issuance of $320 million of senior
unsecured debt Holdings entered into a series of interest rate lock agreements during the second quarter of 2005 to hedge exposure to interest rate fluctuations for $250 million of the senior unsecured debt. These agreements were designated as cash
flow hedges under SFAS No. 133. Holdings settled the rate lock agreements in conjunction with the issuance of the debt, therefore the hedge was determined to be 100% effective. As a result of the settlement, Holdings received $7.4 million in
cash and recorded $4.3 million in the statement of comprehensive income, net of deferred taxes of $3.1 million. Amounts recorded in comprehensive income related to these agreements will be recognized as an approximate $0.3 million reduction of
annual interest expense through August 2015, and an approximate $0.2 million annual reduction from September 2015 through August 2035.



Commodity Price Risk. Both Holdings and Duquesne Light are exposed to commodity price risk arising from market price fluctuations in electricity
supply. We manage this risk by entering into energy commodity contracts, principally through Duquesne Power.



The energy commodity contracts have been structured to begin and end primarily during the POLR III time period. The net result of these transactions is
that, as of September 30, 2005, Duquesne Power had secured substantially all of the combined expected load obligation for its full-requirements contracts with Duquesne Light and DLE.



If Duquesne Power does not enter into contracts for the remaining portion of its anticipated obligations, it will acquire
the necessary supply through spot market purchases, and will therefore be exposed to



35



---

market risk. Assuming Duquesne Power were to make such spot market purchases, we performed a sensitivity analysis using a
hypothetical 10% increase in the projected forward market prices of electricity supply in our valuation model. The analysis indicated that such market movements would change the projected cost of acquiring electricity supply by approximately $3.5
million for the remaining POLR III period through 2007. The projected forward market prices used in our valuation model are derived from broker quotes for the applicable delivery points for both on-peak and off-peak power. Our valuation model
seasonalizes annual or quarterly prices based on historical trends. Actual costs in the future may differ significantly from our analysis, however, based on changes in the timing and amount of commodity price fluctuations and our actual exposures.



The fair value of the sale contracts, and certain purchase
contracts that are classified as derivative instruments, is recorded as mark-to-market derivative assets or liabilities in the condensed consolidated financial statements.



The mark-to-market contracts are exposed to commodity price risk based on price changes in the forward energy market.
Therefore, as the forward market prices change, so will the fair value of these contracts. A hypothetical 10% increase or decrease in the projected forward market prices of electricity supply would increase or decrease the fair value of our
mark-to-market energy contracts by approximately $10.9 million as of September 30, 2005.



As a result of fixed POLR prices for our residential and small commercial customers through December 31, 2007, and customers being able to initiate switches to and from POLR service, we have an additional risk of
loss. Specifically, customers could opt for POLR service in a period of high energy prices or leave POLR service for an alternative generation supplier in a period of low energy prices. Significant changes in customer switching behavior could cause
Duquesne Powers energy supply portfolio to be disproportionate to its full requirements obligations to Duquesne Light and DLE. Accordingly, Duquesne Power could be required to purchase or sell power in periods of high or low prices which could
result in a loss.



During the third quarter of 2005, one
alternative supplier notified Duquesne Light that their customers would be returning to POLR service beginning in the fourth quarter of 2005. Had these customers been served under the POLR arrangement during the nine months ended September 30,
2005, the POLR retention for residential and small commercial customers would have increased approximately 1%. Once these customers return to POLR service, essentially all of the residential customers that are not currently on POLR service are
served by one alternative supplier. Should this alternative supplier also return these residential customers to POLR service, the POLR retention for residential and small commercial customers would increase approximately 10%.



We mitigate risks associated with our POLR obligation by contracting for firm
energy purchases within a range of probabilities based on historical customer retention rates and switching trends along with projected forward energy prices.



Credit/Default Risk.Our credit risk is the exposure to the possibility of economic loss that would occur as a result of nonperformance by
counter-parties of their contractual obligations.



As part of
our overall risk management strategy, Duquesne Power has entered into fixed-price energy contracts with eight investment-grade suppliers and has contracted for unforced capacity credits from six suppliers.



As of September 30, 2005, Duquesne Power has contracted to purchase from
one supplier approximately 56%, 40% and 35% of the notional values of the energy commodity contracts for the years ended December 31, 2005, 2006 and 2007, with no other supplier representing as much as 25% for each of the respective years.



Duquesne Powers energy commodity contracts contain
certain safeguards designed to mitigate potential losses by requiring collateral to be posted by either party depending on changes in energy or capacity prices.



As of October 31, 2005, no collateral was required to be posted under these contracts.



Duquesne Light purchases energy and capacity, beginning January 1, 2005,
under a full-requirements contract from two investment grade suppliers for sale to its large commercial and industrial customers receiving fixed-price POLR III service. Duquesne Lights contracts only require collateral to be posted by the
counter-party. As of October 31, no collateral was required to be posted under these contracts.



In addition to collateral postings, supplier default risk is further mitigated by accelerated damage payment terms. If a supplier fails to deliver the
contracted power, we may exercise our right to force the supplier to compensate us for the difference between the market price and the contracted price of power. If such supplier would fail to make the accelerated damage payments, the supplier would
be in default and we would be permitted to apply any funds due that supplier against our excess energy costs.



36



---

Other than large commercial and industrial POLR III customers on hourly-priced service, Duquesne Light is
obligated to serve its POLR III customers at fixed rates. Duquesne Power is also contractually obligated to serve its customers, Duquesne Light and DLE, at fixed rates. If an energy supplier to Duquesne Light or Duquesne Power were to default on its
contract, we could potentially be acquiring energy and/or capacity at a cost in excess of our revenues, resulting in a loss, if the collateral provisions were not sufficient to cover such excess.



If this would occur it is uncertain, under the current PUC-approved POLR III
arrangement, that Duquesne Light could pass any additional costs related to these energy and capacity purchases on to its customers.



Tax Credit Phase-Out.Section 29 tax credits are subject to a phase-out provision that reduces tax credits as the average annual wellhead
price per barrel of domestic crude oil increases into an inflation-adjusted phase-out range. For 2004, the tax credit would have begun to phase out if the annual average wellhead price of domestic crude oil had exceeded $51.35 per barrel and would
have been completely phased out if the annual average wellhead price of domestic crude oil had exceeded $64.47 per barrel.



The 2005 phase-out range will be calculated using inflation rates published in 2006 by the IRS. We have estimated that for 2005 the tax credits will begin
to phase out if the annual average wellhead price of domestic crude oil exceeds approximately $52 per barrel and will be completely phased out if that price exceeds approximately $66 per barrel. For the first ten months of 2005 the
estimated average wellhead price was approximately $50 per barrel. In order for the price to reach the low end of the phase-out range, the estimated average wellhead price would need to be approximately $64 per barrel for the remainder of 2005.
Based on both the average wellhead price to date and current futures prices for the remaining months of 2005, we do not anticipate that there will be a phase-out of tax credits in 2005.



If domestic crude oil prices continue to increase over the remainder of 2005 and stay at a high level in 2006 and/or 2007,
the estimated tax credits to be generated from DQE Financials landfill gas operations and investment in a synthetic fuel partnership of approximately $20 million, as well as Duquesne Energy Solutions estimated annual after-tax earnings
of approximately $20 million from its synthetic fuel facilities management contract may be substantially reduced or eliminated. However, due to significant levels of tax credit carry-forwards existing at Holdings, the potential phase-out of DQE
Financials tax credits in 2006 and 2007 would not adversely impact our cash flow in those years. Based upon our evaluation, we have thus far determined not to enter into hedging arrangements to reduce this potential exposure.



In addition, as of September 30, 2005, we have certain tangible and
intangible assets related to DQE Financials landfill gas operations with a net book value of approximately $6 million that may become impaired if domestic crude oil prices continue to increase in the future. As of September 30, 2005, we
have no net book value related to synthetic fuel assets or investments.



Item 4. Controls and Procedures.



Disclosure Controls
and Procedures



Management of both Holdings and Duquesne
Light, with the participation of each entitys Chief Executive Officer and the Chief Financial Officer, has evaluated their respective disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange
Act of 1934, as amended) as of the end of the period covered by this report. Each entitys Chief Executive Officer and the Chief Financial Officer have concluded that these controls and procedures are effective to ensure that the information
required to be disclosed in Holdings and Duquesne Lights reports under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC.



Changes in Internal Control Over Financial Reporting



There have been no changes in Holdings or Duquesne Lights
internal control over financial reporting during the third quarter that have materially affected, or are reasonably likely to materially affect, such internal control over financial reporting.



PART II. OTHER INFORMATION.



Item 1. Legal Proceedings.



Shareholder Class Action. In October and November 2001, a number of
putative class action lawsuits were filed by purported shareholders of Holdings against Holdings and David Marshall, our



37



---

former chairman, chief executive officer and president, in the United States District Court for the Western District of
Pennsylvania. These cases were consolidated under the caption In re DQE, Inc. Securities Litigation, Master File No. 01-1851 (W.D. Pa.), and the plaintiffs filed a second consolidated amended complaint on April 15, 2002. The complaint
alleged violations of Section 10(b) of the Securities Exchange Act of 1934 (Exchange Act) and Rule 10b-5 promulgated thereunder, and Section 12(a)(2) of the Securities Act of 1933 (Securities Act). The complaint also alleged controlling
person liability under Section 20(a) of the Exchange Act and Section 15 of the Securities Act. The complaint alleged that between December 6, 2000 and April 30, 2001, the defendants issued a number of materially false and
misleading statements concerning investments made by our subsidiary, DQE Enterprises, Inc., and the impact that these investments would have on our current and future financial results.



On May 20, 2003, the court certified a class to include purchasers of our common stock during the period from
December 6, 2000 through April 30, 2001, and a sub-class to include purchasers of our common stock through our dividend reinvestment and stock purchase plan during the same period.



On October 7, 2005 the court approved a final settlement of all claims.
Our insurance covers the settlement in full.



Other. We
are involved in various other legal proceedings and environmental matters. We believe that the resolution of such proceedings and matters, in total, will not have a materially adverse effect on our financial position, results of operations or cash
flows.
