                        METRETEK TECHNOLOGIES ENTERS INTO
                        NEW AND EXPANDED CREDIT FACILITY

DENVER - SEPT. 7, 2005 - METRETEK TECHNOLOGIES, INC. (AMEX: MEK) announced today
that it has entered into a credit agreement with First National Bank of Colorado
for a $4.5 million revolving line of credit facility. The Company said that the
credit facility will be used to fund the growth of its PowerSecure, Inc. and
Metretek, Incorporated subsidiaries, and to generally provide for its working
capital requirements. The new credit facility replaces and expands the company's
current $3.26 million credit agreement, which is being terminated. The First
National Bank of Colorado credit facility matures in September 2007.

"We are extremely pleased to enter into this refinancing and to take the next
step in significantly strengthening our capital resources and our liquidity,"
said W. Phillip Marcum, the Company's president and chief executive officer. "By
entering into this new credit facility, we are expanding the resources we can
commit to our PowerSecure subsidiary and to the development of the telemetry
business at our Metretek Florida subsidiary." Marcum noted that the new credit
facility should increase the Company's overall average borrowing availability by
approximately $2 million.

Marcum also indicated that this new bank facility completes the debt
restructuring that the Company initiated earlier in the year. According to
Marcum, "With the new credit facility and the $5 million Caterpillar Financial
Services Corporation facility that was completed in May, we now have sufficient
capital facilities to aggressively pursue PowerSecure's growth strategies
through at least 2006."

Metretek Technologies, Inc. through its subsidiaries -- Southern Flow Companies,
Inc.; PowerSecure, Inc.; and Metretek, Incorporated (Metretek Florida) -- is an
energy services and technology company, providing diversified energy products,
services and technology to industrial and commercial users and suppliers of
natural gas and electricity.

concerning the effects of the new credit facility on the Company's future
capital resources and liquidity and its ability to satisfy the growth
requirements of PowerSecure and Metretek Florida and the working capital
requirements of the Company, as well as the Company's expected borrowing
