Second Quarter 2011 Financial Results

Revenues decreased $0.6 million to $444.9 million for the second quarter 2011 compared to $445.5 million for the same period in 2010.  This decrease was primarily the result of lower retail and wholesale sales volumes partially offset by higher average retail rates, higher average wholesale prices, and an increase in RTO capacity revenues.

Retail revenues increased $5.4 million resulting primarily from the continued recovery of fuel, energy efficiency, transmission and capacity costs partially offset by a slight reduction in retail sales volumes as cooling degree days were 15% lower than in the second quarter of 2010.

Wholesale revenues decreased $10.4 million primarily as a result of a 34% decrease in wholesale sales volume, partially offset by an 11% increase in average wholesale prices.  RTO, RTO capacity and other revenues increased $4.4 million primarily due to an increase in PJM capacity revenue.

Other Revenues	(1.1		)	3.2		(4.3		)
Total Revenues	$	444.9		$	445.5	(0.6		)

For the six months ended June 30, 2011, revenues increased $42.9 million, or 5%, to $939.6 million compared to $896.7 million for the same period in 2010.

Fuel costs, which include coal, gas, oil, and emission allowances (net of gains on sales), increased $1.2 million, or 1%, for the second quarter 2011 compared to the same period in 2010. The increase was primarily due to a 13% increase in average fuel prices and a $0.3 million net reduction in gains realized from emission allowance and coal sales. Partially offsetting these increases was a 17% reduction in generation volume.

For the six months ended June 30, 2011, fuel costs decreased $0.9 million to $191.9 million compared to $192.8 million for the same period in 2010.

Purchased power costs increased $22.7 million, or 25%, for the second quarter 2011 compared to the same period in 2010.  This increase was primarily due to a $34.5 million increase in purchased power volumes and a $4.5 million increase in RTO capacity and other RTO charges, partially offset by a $10.1 million decrease in average purchased power prices.

For the six months ended June 30, 2011, purchased power costs increased $70.7 million, or 43%, to $234.4 million compared to $163.7 million for the same period in 2010.

Gross margin decreased $24.5 million, or 9%, to $239.2 million for the second quarter 2011 compared to $263.7 million for the second quarter of 2010.  For the six months ended June 30, 2011, gross margin decreased $26.9 million, or 5%, to $513.3 million compared to $540.2 million for the same period in 2010.

Operation and maintenance expense increased $19.3 million, or 22%, for the second quarter 2011 compared to the same period in 2010.  The increase was primarily attributable to an $8.7 million increase in costs at DPL’s generating facilities due largely to the timing of planned generation plant outages, $5.8 million of merger related costs, a $3.5 million increase in costs which are funded through rate riders, and a $2.2 million increase in storm and line clearance costs.

For the six months ended June 30, 2011, operation and maintenance expense increased $38.1 million, or 23%, to $206.2 million compared to $168.1 million for the same period in 2010.

Depreciation and amortization expense decreased $0.6 million, or 2%, for the second quarter 2011 compared to the same period in 2010.  This decrease was primarily due to lower depreciation rates on generation property which were implemented during the third quarter of 2010.

For the six months ended June 30, 2011, depreciation and amortization expense decreased $2.9 million, or 4%, to $70.2 million compared to $73.1 million for the same period in 2010.

General taxes increased $0.3 million, or 1%, for the second quarter 2011 compared to the same period in 2010 primarily due to higher property tax accruals.

For the six months ended June 30, 2011, general taxes increased $6.6 million, or 10%, to $70.3 million compared to $63.7 million for the same period in 2010.

3

Interest expense increased $0.1 million, or 1%, for the second quarter 2011 compared to the same period in 2010.  The increase was primarily due to a $2.0 million write-off of the ineffective portion of DPL’s existing interest rate hedges offset by a reduction to interest expense due to the purchase of the DPL Capital Trust II 8.125% capital securities noted below.

For the six months ended June 30, 2011, interest expense decreased $0.9 million, or 3%, to $34.5 million compared to $35.4 million for the same period in 2010.

Charge for the early redemption of debt

DPL purchased $122.0 million principal amount of DPL Capital Trust II 8.125% capital securities in a privately negotiated transaction in February 2011.  As part of this transaction, DPL paid a $12.2 million, or 10%, premium and recognized $3.1 million of unamortized discount and issuance costs during the first quarter 2011.

Income taxes decreased $13.8 million, or 46%, for the second quarter 2011 compared to the same period in 2010 primarily due to a decrease in pre-tax income.

For the six months ended June 30, 2011, income taxes decreased $25.4 million, or 38%, to $41.1 million compared to $66.5 million for the same period in 2010.

Liquidity and Cash Flow

DPL’s cash and cash equivalents totaled $72.8 million at June 30, 2011 compared to $124.0 million at December 31, 2010.  The decrease in cash and cash equivalents was primarily attributed to $134.2 million related to the purchase of DPL Capital Trust II 8.125% capital securities, $91.4 million of capital expenditures, $76.4 million of dividends paid on common stock, $8.2 million related to the acquisition of MC Squared Energy Services, LLC, and the posting of $13.5 million of MC Squared debt and collateral, partially offset by $185.1 million of cash generated from operating activities, net sales of $69.2 million of short-term investments, and proceeds from warrant exercises of $14.7 million.

As of July 28, 2011, DP&L had no borrowings on its combined revolving credit facilities.  As a result, we currently have $420 million available on the combined revolving credit facilities.

Construction additions were $86.8 million during the six months ended June 30, 2011.  Capital projects are subject to continuing review and are revised in light of changes in financial and economic conditions, load forecasts, legislative and regulatory developments and changing environmental standards, among other factors.  For the period 2011 through 2013, DPL is projecting to spend an estimated $770 million on capital projects.

Retail Competition Update

The annualized percentage of DP&L’s retail load (in MWHs) that has switched to Competitive Retail Electric Service (“CRES”) providers increased from 47% at the end of the first quarter 2011 to 51% currently. 

4

However, DPL Energy Resources (“DPLER”), our retail marketer affiliate, supplies approximately 85% of the switched load.  The change in the annualized switched load reflects increased switching to unaffiliated CRES providers and residential shopping which began during the second quarter 2011.  Approximately 6% of DP&L’s annualized residential load switched to CRES providers during the past two months with DPLER acquiring 54% of the switched load.  For the calendar year 2011, based on current trends, we project customer shopping will negatively impact gross margin by approximately $40 to $45 million compared to the 2010 impact of approximately $17 million.

Current Annualized Estimate	% of MWHs
Retail Load Supplied by DP&L	49	%
CRES Share of DP&L Load
DPLER Share of DP&L Load	44	%
3rd Party Share of DP&L Load	7	%
Total CRES Provided Load	51	%
Total Retail Load	100	%

2011 Earnings Guidance

DPL has reaffirmed its 2011 adjusted earnings from continuing operations guidance of $2.30 to $2.55 per share and currently expects its adjusted earnings from continuing operations to be at the lower end of its guidance.   Adjusted earnings from continuing operations is a non-GAAP financial measure which excludes the impacts of the first and second quarter 2011 special items totaling $0.23 per share, as reflected in the non-GAAP to GAAP earnings per share reconciliation above, and also excludes estimated merger transaction costs for the balance of the year which are reflected in the full-year 2011 non-GAAP to GAAP earnings per share reconciliation on the last page of this press release.

Non-GAAP Financial Measures

This press release contains non-GAAP financial measures as defined under Securities and Exchange Commission regulations. Generally, a non-GAAP financial measure is a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles (GAAP) in the United States.

DPL’s earnings per share is prepared in accordance with accounting principles generally accepted in the United States of America and represent the company’s earnings per share as reported in DPL’s financial statements filed with the Securities and Exchange Commission.  Adjusted earnings per share is a non-GAAP financial measure. DPL’s management believes the adjusted earnings per share to be relevant and useful information to our investors as this measure excludes certain special items. Management feels this is a meaningful analysis of our financial performance as it is not obscured by these special events.  This non-GAAP measure is also used by management in evaluating the company’s ongoing operating performance.  Adjusted earnings per share is not a substitute for measures determined in accordance with GAAP, and may not be comparable to adjusted earnings per share amounts reported by other companies.  The estimated range of non-GAAP earnings per share for full-year 2011 included in this press release includes known adjustments and one projected adjustment.  Additional events may arise that could affect the projected adjustment and/or give rise to additional adjustments for estimated or actual 2011 non-GAAP earnings per share information disclosed by DPL in the future.
