September 2, 2011

Dear Fellow Shareholder:

The September 23, 2011 Annual Meeting of Shareholders of DPL Inc. is fast approaching, and according to our latest records, we have not yet received your vote.  Your Board of Directors unanimously recommends that you vote today FOR the proposed merger with a wholly-owned subsidiary of The AES Corporation.

Since approval of the merger requires the affirmative vote of two-thirds of the outstanding shares of common stock, your vote is very important, no matter how many or how few shares you may own.  If you fail to vote, it will have the same effect as a vote against the proposed merger.  If you hold your shares in more than one account, you may have received more than one proxy card.  To make sure your shares are represented, please vote today FOR the transaction by telephone, via the Internet, or by signing, dating and returning the enclosed proxy card in the postage-paid envelope provided.

Thank you for your support.

Very truly yours,

Timothy G. Rice

Vice President, Assistant General Counsel

and Corporate Secretary

YOUR VOTE IS IMPORTANT!

Failing to Vote on the Proposed Merger has the Same Effect as a Vote “Against” the Proposed Merger

Remember, you can vote your shares by telephone, via the Internet, or by signing, dating and returning the enclosed proxy card.

Please follow the easy instructions on the enclosed proxy card.

If you have any questions, or need assistance in voting

your shares, please call our proxy solicitor,
