          METRETEK TECHNOLOGIES RECEIVES NASDAQ DELISTING NOTIFICATION

               -- Requests Hearing for Appeal to Retain Listing --


DENVER - AUGUST 20, 2002 - METRETEK TECHNOLOGIES, INC. (NASDAQ:MTEK) today
announced that it received a Nasdaq Staff Determination letter on August 14,
2002, indicating that the Company was not in compliance with the $1.00 minimum
bid price requirement for continued listing on the Nasdaq SmallCap Market, set
forth in Marketplace Rule 4410(c)(8)(D), and that the Company was not eligible
for an additional grace period because it did not meet the $5 million
stockholders' equity requirement under Marketplace Rule 4310(c)(2)(A).

The Staff Determination letter informed the Company that, due to such
non-compliance, the Company's common stock was subject to delisting from the
Nasdaq SmallCap Market. The Company has requested a hearing before a Nasdaq
Listing Qualifications Panel to review the Staff Determination. The Company has
been advised by Nasdaq that the hearing request will stay the delisting pending
the outcome of the hearing, the date of which has not yet been set. There can be
no assurance that the Panel will grant the Company's request for continued
listing. If the Panel upholds the Staff Determination, the Company's common
stock will be delisted from the Nasdaq Small Cap Market. If the common stock is
delisted, it is expected to be traded on the Over-the-Counter (OTC) Bulletin
Board.

Metretek Technologies, Inc. through its subsidiaries -- PowerSecure, Inc.;
