Annual Meeting May 27

     You soon will be receiving our 2003 Annual Report, along with proxy
material for the Annual Meeting of Shareholders, which will take place at 10
a.m., Thursday, May 27, at the Manchester Craftsmen's Guild Auditorium, located
at 1815 Metropolitan St. on Pittsburgh's North Shore.

     As noted in this newsletter over the past two years, the goal of our
Back-to-Basics strategy was to transition our company back to a traditional
electric utility business with a strong balance sheet, a predictable earnings
stream and a focus on shareholder value. The 2003 annual report, which also will
be available for viewing on our website, www.duquesnelight.com, details how the
company has done exactly what it told shareholders we planned to do when we
began implementing that vision. At the May 27 annual meeting, I look forward to
sharing with you how Duquesne Light is building its future as we continue to
meet the commitments made when we announced the Back-to-Basics plan.

     The proxy material enclosed with the annual report details proposals to be
voted on at the meeting, including the election of directors, approval of
amendments to the 2002 Long-Term Incentive Plan and ratification of Deloitte &
Touche LLP as auditors. Each proposal is fully explained in the "Notice of 2004
Annual Meeting and Proxy Statement."

     Shareholders who owned common stock, as of March 10, 2004, are eligible to
vote and to attend the meeting. Whether or not you plan to attend, I encourage
you to vote your proxy.

Register Your Vote Electronically
     More than a third of the votes at last year's annual meeting were
registered electronically. Once again, we are offering shareholders the option
of electronic voting of their proxy via the telephone or through the Internet.
Using this free service will enable us to process votes quicker and save money.

     You will be able to vote your shares at your convenience. Telephone and
Internet voting will be accepted 24 hours a day, seven days a week, through May
26.

     To vote by Internet, go to www.votefast.com and follow the simple
instructions. Make sure you have your proxy card available when you access the
website.

     To vote by telephone, also have your proxy card available and follow the
simple instructions when you call the toll-free number, 1-800-542-1160. A
touch-tone telephone is needed to use this option.

     If you prefer to vote by mail, please mark, sign and date your proxy card
and return it in the postage-paid envelope to Duquesne Light Holdings, Inc., Box
68, Pittsburgh, PA 15230.

     If you have not received your proxy material by May 1, please call us using
our toll-free Shareholder Relations number, 1-800-247-0400 (412-393-6167 in
Pittsburgh).

     Again, I look forward to sharing the significant progress we made last year
with those of you who plan to attend our annual meeting.

Sincerely,


/s/ Morgan K. O'Brien
