                          METRETEK TECHNOLOGIES REPORTS
                           FIRST-QUARTER 2005 RESULTS


DENVER - MAY 16, 2005 - For the three months ended March 31, 2005, METRETEK
TECHNOLOGIES, INC. (OTCBB: MTEK) reported revenues of $7.8 million and income
from continuing operations of $22,000, or $0.00 per share on 12,733,632 diluted
weighted average common shares outstanding. In the comparable period a year ago,
the Company reported revenues of $8.4 million and income from continuing
operations of $339,000, or $0.01 per share on 6,815,957 diluted weighted average
common shares outstanding. Including losses on discontinued operations, the
first-quarter 2005 net loss was $278,000, compared to the first-quarter 2004 net
income of $4,000.

The increase in weighted average common shares outstanding reflects several
equity transactions completed in 2004, including a private placement of
approximately 3.5 million shares of common stock, related transactions that
resulted in the conversion of 2,750 shares of preferred stock to 1.4 million
shares of common stock, and the acquisition of the outstanding minority
shareholder interest in the Company's PowerSecure subsidiary via the issuance of
950,000 shares of common stock.

According to W. Phillip Marcum, president and chief executive officer, "While
revenues and net income decreased slightly from the prior year, we remain very
pleased with the overall progress of all of our business operations. As we have
noted in the past," said Marcum, "significant quarterly revenue fluctuations are
inherent in the Company's operations, particularly within its PowerSecure
subsidiary. Overall, we remain very much on track to meet our guidance estimates
and we are reaffirming our guidance for 2005."

As previously stated, 2005 revenues are expected to be in the range of $41
million to $42 million, with net income of approximately $3.0 million, or
approximately $0.25 per basic share.

The decrease in consolidated revenues stems from lower revenues at both Metretek
Florida and PowerSecure, partially offset by slightly higher revenues at
Southern Flow due primarily to higher natural gas prices. "Lower revenues at
Metretek Florida ($644,000 compared to $875,000 a year ago) reflect shipments
that were deferred to the second quarter due to delays related to the transition
of production activities from internal to external contract manufacturers," said
Marcum. "The decrease in PowerSecure revenues, to $3.8 million from $4.2 million
a year ago, is attributable to normal quarterly fluctuations, typically
resulting from project timelines and the timing of revenue recognition on larger
turnkey distributed generation projects."

The purchaser of Metretek Florida's contract manufacturing business, which the
Company discontinued in the third quarter of 2004, recently notified the Company
that it intends to terminate operations of the acquired business. As a result of
this development, the Company conducted a preliminary review of its provisions
related




to disposal of the discontinued manufacturing operation. Based upon this
analysis, the Company's first quarter 2005 results include an additional
$300,000 non-cash charge for losses that are expected to be incurred on the
disposal of remaining assets of the discontinued operation.

Adjusted EBITDA:
Adjusted EBITDA for the three months ended March 31, 2005 was $378,000, compared
to $636,000 for the three months ended March 31, 2004, a $258,000 decrease. As
computed by the Company, adjusted EBITDA is a non-GAAP financial measure (as
such term is defined by the Securities and Exchange Commission) computed as
income from continuing operations before interest and finance charges, income
taxes, depreciation and amortization, and minority interest.

By eliminating certain expenses not necessarily indicative of the results of the
Company's core operations, management believes that adjusted EBITDA offers a
useful tool to measure and monitor the Company's operating performance, and
provides meaningful information to investors in terms of enhancing their
understanding of the Company's core operating performance and results. Adjusted
EBITDA is also used by management to assist in planning and forecasting future
operations. However, adjusted EBITDA as defined by the Company may not be
directly comparable to similarly defined measures as reported by other
companies. Adjusted EBITDA should be considered only as a supplement to, and not
as a substitute for or in isolation from, other measures of financial
performance and liquidity reported in accordance with generally accepted
accounting principles ("GAAP"), such as net income.
