DPL REPORTS SECOND QUARTER EARNINGS

— Maintains 2006 Earnings Guidance —

DAYTON, Ohio, August 1, 2006 – DPL Inc. (NYSE: DPL) today reported basic earnings from continuing operations of $0.20 per share for the second quarter of 2006 compared to $0.14 per share for the second quarter of 2005. Total basic earnings were also $0.20 per share for the second quarter of 2006, since there were no earnings from discontinued operations. For the second quarter of 2005, total basic earnings were $0.18 per share, which included earnings from discontinued operations of $0.04 per share resulting from the sale of the private equity portfolio in 2005.

“Operational efficiency continues to improve,” stated Jim Mahoney, DPL President and Chief Executive Officer. “In addition, the ability to more fully recover our retail fuel and regulatory costs, as well as increased year-to-date plant availability for wholesale sales, helped offset reduced retail sales due to mild weather.”

For the six months ended June 30, 2006, basic earnings per share from continuing operations were $0.63 compared to $0.44 in 2005. Including discontinued operations, total basic earnings per share were $0.70 in 2006 versus $0.79 in 2005 for the six month period. The difference in the six month total basic earnings per share was primarily due to the inclusion of $0.35 per share in earnings from discontinued operations from the sale of the private equity portfolio in 2005 versus $0.07 per share for 2006, offset by a $0.19 per share increase in earnings from continuing operations in 2006.

Second Quarter and Year-To-Date Financial Results

Total revenues increased 5% to $309.0 million in the second quarter of 2006 compared to $293.4 million for the second quarter of 2005, reflecting higher average rates for retail and wholesale sales and greater wholesale sales volume. These increases were partially offset by lower retail sales volume, as cooling degree-days were down 26% compared to the same period for 2005.

	Three Months Ended June 30,
$  in millions	2006		2005		Variance
Electric Revenues - Retail	$	258.2	$	248.6	$	9.6
Electric Revenues – Wholesale	30.5		24.7		5.8
Electric Revenues – RTO ancillary	17.4		17.5		(0.1		)
Other Revenues, Net of Fuel Costs	2.9		2.6		0.3
Total Revenues	$	309.0	$	293.4	$	15.6

For the six months ended June 30, 2006, total revenues increased 8% to $650.1 million compared to $600.5 million for the same period in 2005.

Fuel, which includes coal, gas, oil and emission allowance costs, increased by $7.4 million, or 10%, in the three months ended June 30, 2006 compared to the same period in 2005 driven by increased market prices.

	Three Months Ended June 30,
$  in millions	2006		2005		Variance
Coal	$	72.6	$	64.1	$	8.5
Gas	3.1		2.1		1.0
Oil	1.8		1.3		0.5
Emission Costs	1.1		3.7		(2.6		)
Total Fuel Costs	$	78.6	$	71.2	$	7.4

Fuel costs rose by $13.1 million, or 9%, in the first half of 2006 compared to 2005 as a result of higher market prices and higher generation output as compared to 2005.

Purchased power decreased by $0.5 million, or 1%, in the second quarter compared to the same period in 2005 primarily due to lower purchased power volume and ancillary charges.

	Three Months Ended June 30,
$  in millions	2006		2005		Variance
Purchased Power	$	24.9	$	25.0	$	(0.1	)
RTO Ancillaries	12.1		12.5		(0.4		)
Total Purchased Power	$	37.0	$	37.5	$	(0.5	)

Purchased power costs decreased by $4.0 million, or 6%, in the first half of 2006 compared to the prior year resulting from lower purchased power volume, offset slightly by higher average regional transmission organization (RTO) ancillary costs.

Gross margin (revenues minus fuel and purchased power) of $193.4 million for the second quarter of 2006 increased by $8.7 million from $184.7 million for the second quarter of 2005. This increase was driven mostly by the ability to recover additional retail fuel and regulatory costs.

Gross margin in the first half of 2006 increased to $425.0 million, or 11%, from $384.5 million in the first half of 2005.

Operation and maintenance expense increased $11.7 million for the three months ended June 30, 2006 compared to the same period in 2005. The increase includes $3.3 million in PJM administrative fees, comprised of $0.8 million of ongoing PJM costs and a non-recurring credit in 2005 of $2.5 million. DP&L began recovering PJM administrative fees in February of 2006. Other reasons for the higher operation and maintenance expense were an increase of $3.4 million in legal costs, $2.6 million in employee compensation and benefit expenses, $2.1 million in power production costs, $1.3 million in additional insurance reserves, and $0.8 million in a low-income assistance program. These increases were partially offset by a $3.5 million decrease in mark-to-market adjustments for restricted stock units.

Operation and maintenance expense increased $20.4 million for the six months ended June 30, 2006 compared to the same period in 2005.

Interest expense decreased $11.4 million, or 31%, for the second quarter of 2006 compared to the same period in 2005 primarily due to debt reduction of nearly $450 million, most of which occurred in the third quarter of 2005.

For the six months ended June 30, 2006 versus 2005, interest expense declined $24.2 million or 32%.

Other income increased $0.8 million in the second quarter of 2006 compared to the second quarter of 2005.

For the six months ended June 30, 2006, other income declined $10.9 million from the same period in 2005 reflecting a $12.3 million gain realized in 2005 from the sale of pollution control emission allowances. There were no emission allowance sales in 2006.

Liquidity and Cash Flow

DPL’s cash and cash equivalents totaled $249.9 million at June 30, 2006, compared to $595.8 million at December 31, 2005, a decrease of $345.9 million. This decrease was primarily due to the stock buyback program and increased capital expenditures. In addition, DPL had no short-term investments available for sale at June 30, 2006 compared to $125.8 million at December 31, 2005.

Capital expenditures were $200.3 million for the first half of 2006 and $81.2 million for the first half of 2005. Total capital additions are expected to approximate $365 million in 2006 primarily related to DPL’s flue gas desulfurization (scrubber) construction program at its generating plants. DPL expects to finance its capital additions in 2006 with a combination of cash on hand, tax-exempt debt and internally-generated funds.

Capital Forecast

Over the next three years (2006 – 2008), DPL is projecting to spend an estimated $820 million in capital projects, approximately 55% of which is to meet changing environmental standards. This forecast represents a $70 million increase over the projection at March 31, 2006 mainly due to revised capital expenditure forecasts at both DPL-operated and partner-operated plants.

Fuel Forecast

Fuel costs are forecasted to increase approximately 7% in 2006 compared to 2005 and to be flat in 2007 compared to 2006. Previously, DPL had projected fuel costs to be flat in 2006 compared to 2005 and increase 5% in 2007 compared to 2006. The forecast revision is due to anticipated increased generation volume in 2006 at a co-owned plant due to a change in a scheduled outage.

DPL’s coal requirements are approximately 95% hedged for 2006 and 83% for 2007.

Stock Buyback

As of June 30, 2006, DPL has repurchased nearly 13 million shares at a cost of $348.2 million. The stock buyback is part of a previously announced $400 million program that is expected to be completed in the third quarter of 2006.

Peaker Review

As previously announced, DPL is reviewing its peaking generation portfolio. As a part of that process, the Company is soliciting bids for three peaking generating sites, representing a capacity of 872 megawatts. DPL will determine the number of sites to sell, if any, after it receives the bids, which are expected in early September, and evaluates both the price and terms of the bids.

Chief Executive Officer Search

The DPL Board of Directors has formed a five-person search committee to identify a successor to current chief executive officer James Mahoney, who announced his resignation this past spring. The committee has interviewed a number of candidates and continues to make progress. In the interim, Mr. Mahoney will remain in his position as CEO.

“We are pleased with where we are in the search process,” said Glenn Harder, DPL Chairman of the Board. “The logistics of arranging interviews have caused it to take longer than originally anticipated. In the meantime, Jim has been gracious enough to continue as CEO to ensure a smooth transition.”

Future Outlook

The Company reaffirmed its basic earnings per share from continuing operations guidance of $1.35 to $1.50 for 2006 and $1.65 to $1.80 for 2007.

Conference Call/Webcast

DPL will conduct a webcast conference call with financial analysts on Wednesday, August 2, 2006, at 9:00 a.m. Eastern Time to discuss results.
