DPL Reports Improved First Quarter Earnings

DAYTON, Ohio—April 30, 2007—DPL (NYSE: DPL) today reported basic earnings from continuing operations of $0.48 per share for the first quarter of 2007 compared to $0.43 per share for the first quarter of 2006, a 12% increase.

Total basic earnings were $0.52 per share for the first quarter of 2007, which included $0.04 per share in earnings from discontinued operations resulting from recognition of the final deferred gain from the sale of the private equity funds in 2005. For the same period in 2006, total basic earnings were $0.49 per share, including $0.06 per share in earnings from discontinued operations.

“I am pleased that earnings per share from continuing operations were up 12% in the first quarter this year compared to the same period last year, as we continue to focus upon improved performance of our generating fleet along with ongoing cost control throughout the Company,” stated DPL President and Chief Executive Officer Paul Barbas. ”In that regard, we have recently realigned our leadership team to focus on improvement in these areas. Finally, we will continue to build upon the positive momentum of 2006 created by over 1,400 dedicated employees.”

First Quarter 2007 Financial Results

Revenues increased 11% to $379.7 million for the three months ended March 31, 2007 compared to $341.1 million for the same period in 2006, primarily reflecting higher average rates and sales volume for both retail and wholesale. Heating degree days were 15% higher in the first quarter of 2007 compared to the first quarter of 2006. These increases were partially offset by lower ancillary revenues associated with participation in the PJM and MISO markets.

	Three Months Ended March 31,
$ in millions	2007		2006		Variance
Electric Revenues – Retail	$	304.5	$	283.3	$	21.2
Electric Revenues – Wholesale	56.7		37.4		19.3
Electric Revenues – RTO ancillary	15.7		17.7		(2.0		)
Other Revenues, Net of Fuel Costs	2.8		2.7		0.1
Total Revenues	$	379.7	$	341.1	$	38.6

Fuel, which includes coal, gas, oil and emission allowance costs, increased $6.1 million, or 7%, in the first quarter 2007 compared to the same period in 2006, primarily as a result of increased fuel prices and higher generation output. Even with this increase, we continue to anticipate our total fuel costs for 2007 to be relatively flat compared to 2006.

	Three Months Ended March 31,
$ in millions	2007		2006		Variance
Coal	$	87.5	$	81.5	$	6.0

Oil	1.3		1.3		0.0
Emission Allowance Costs	0.1		0.8		(0.7		)
Total Fuel Costs	$	90.3	$	84.2	$	6.1

Purchased power costs increased $26.9 million in the first quarter of 2007 compared to the same period in 2006 resulting from increased charges of $22.3 million relating to higher purchased power volume due primarily to planned and unplanned outages at both DPL-operated and partner-operated generating plants and a $4.4 million increase due to higher average market rates.

	Three Months Ended March 31,
$ in millions	2007		2006		Variance
Purchased Power	$	39.8	$	13.1	$	26.7
RTO Ancillaries	12.4		12.2		0.2
Total Purchased Power	$	52.2	$	25.3	$	26.9

Gross margin of $237.2 million for the three months ended March 31, 2007 increased $5.6 million, or 2%, from the same period in 2006. The dollar increase reflects higher retail and wholesale volume and the favorable revenue impact of the rate stabilization plan offset by increased fuel and purchased power costs. As a percentage of total revenues, gross margin decreased to 62.5% in 2007 compared to 67.9% in 2006 due primarily to higher purchased power costs.

Operation and maintenance expense increased $6.9 million, or 11%, in the first quarter 2007 compared to the first quarter 2006. This was primarily due to increases of:

·$4.0 million in legal costs;

·$2.8 million in additional compensation expense due to mark-to-market accounting for restricted stock units (RSUs);

·$2.4 million in power production costs, reflecting higher boiler maintenance and plant operating expenses; and

·$1.9 million in service operation costs resulting primarily from two major ice storms in February 2007.

These increases were partially offset by a $2.5 million decrease in long-term and other incentive compensation, a $0.9 million decrease in pension and benefits expenses, and a $1.3 million decrease in expenses for injuries and damages.

Depreciation and amortization decreased $3.4 million in the first quarter 2007 compared to the first quarter of 2006 reflecting the absence of depreciation on the Darby and Greenville peaking units and the impact of asset retirements.

Amortization of regulatory assets increased $1.8 million to $2.9 million in the first quarter 2007 compared to the same period in 2006. The increase reflects a full quarter of amortization of the customer billing system modifications to accommodate electric choice, deferred PJM administrative fees, and incremental storm costs incurred in 2004 and 2005. These costs are being recovered through retail rate riders that went into effect at various times throughout 2006.

Investment income decreased $3.4 million in the first quarter of 2007 as compared to the same period in 2006, reflecting lower cash and short-term investment balances.

Interest expense for the first quarter of 2007 decreased $3.2 million, or 12%, compared to the same period in 2006. Decreases in interest expense resulted from the redemption of DPL’s $225 million 8.25% Senior Notes, the elimination of the 1% interest penalty on DPL’s $175 million 8% Senior Notes, and higher capitalized interest associated with DP&L’s major construction projects. These decreases were partially offset by additional interest expense resulting from DP&L’s $100 million 4.8% Series Pollution Control Bonds issued September 13, 2006 and $65 million of short-term borrowing from DP&L’s $220 million unsecured revolving credit facility.

Liquidity and Cash Flow

DPL’s cash and cash equivalents totaled $106.4 million at March 31, 2007, compared to $262.2 million at December 31, 2006, a decrease of $155.8 million. In addition, DPL had no restricted funds from the tax-exempt bonds held in trust at March 31, 2007 compared to $10.1 million held in trust at December 31, 2006. The decrease in cash and cash equivalents was primarily attributable to the retirement of DPL’s $225 million 8.25% Senior Notes.

Capital expenditures were $80.5 million in the first quarter 2007 compared to $110.9 million in the first quarter 2006. The decrease reflects the timing of expenditures to fund DPL’s flue gas desulfurization (scrubber) construction program.

Insurance Recovery Claim

On January 13, 2006, DP&L filed a claim against one of its insurers, Associated Electric & Gas Insurance Services (AEGIS), under a fiduciary liability policy to recoup legal fees associated with the litigation against three former executives. On April 30, 2007, DP&L and AEGIS reached a settlement in which AEGIS agreed to pay DP&L $14.5 million for legal fees incurred by DP&L associated with the litigation

against three former executives. This recovery of legal expenses will be recorded in the second quarter 2007.

Peaker Sale Update

During the fourth quarter of 2006, DPL announced the sale of two peaking generating sites, Darby and Greenville. On April 25, 2007, DPL completed the sale transaction for each site and received approximately $151.2 million in cash as a result of closing these transactions. These sale proceeds will be used to pay down short-term borrowings and fund DP&L’s major construction projects.

Future Outlook

Basic Earnings from Continuing Operations – The Company reaffirmed its guidance for basic earnings per share from continuing operations of $1.60 to $1.75 for 2007. This estimate is based on 108 million shares outstanding and includes the recovery of legal expenses resulting from the settlement of the AEGIS claim.

Capital Forecast

Over the three-year period of 2007 through 2009, DPL is projecting to invest an estimated $645 million in capital projects, approximately 40% of which is related to changing environmental standards. This represents a $40 million increase over the previously reported estimate of $605 million, due primarily to increases in the flue gas desulfurization (scrubber) projects at DPL-operated generating plants. With this increase, DPL still believes the flue gas desulfurization projects remain best-in-class from an installed costs/kw basis.

Conference Call/Webcast

DPL will conduct a webcast conference call with financial analysts on Tuesday, May 1, 2007, at 9:00 a.m. Eastern Time to discuss results. Interested parties, including investors and the media, can access the webcast conference call real-time on DPL’s website at www.dplinc.com in the Company’s investor relations section.
