                              PROSPECTUS SUPPLEMENT
                        (TO PROSPECTUS DATED MAY 2, 2000)

                           METRETEK TECHNOLOGIES, INC.

                        3,991,079 SHARES OF COMMON STOCK
                    7,000 SHARES OF SERIES B PREFERRED STOCK


         This prospectus supplement supplements the prospectus dated May 2, 2000
of Metretek Technologies, Inc. relating to the resale of shares of our common
stock and our Series B preferred stock by certain of our securityholders (and by
their donees, pledgees, transferees or other successors in interest that receive
such shares as a gift, pledge, partnership distribution or other non-sale
related transfer). In the prospectus and this prospectus supplement, we refer to
those persons, including those named below in this prospectus supplement, as
selling securityholders.

         This prospectus supplement is incomplete by reference into, should be
read in conjunction with, and is qualified by reference to, the prospectus,
except to the extent that the information contained in this prospectus
supplement supersedes the information contained in the prospectus. Terms used
but not otherwise defined in this prospectus supplement but defined in the
prospectus have the meanings given to them in the prospectus. This prospectus
supplement is not complete without, and may not be delivered or utilized except
in connection with, the prospectus, including any amendments or supplements to
it. All references in the prospectus to "this prospectus" are hereby amended to
read "this prospectus (as supplemented and amended)."

         Recently, two of the selling securityholders named in the prospectus
transferred all of their shares of common stock, warrants to purchase shares of
common stock and shares of Series B preferred stock to their respective partners
for no consideration as partnership distributions. As a result, the information
in the table of selling securityholders and the related notes, contained in the
section entitled "Selling Securityholders" on pages 44 to 48 of the prospectus,
are amended to:

         -        delete Famco Value Income Partners, L.P. and Famco Offshore,
                  Ltd. as selling securityholders; and

         -        add the additional selling securityholders and related
                  information contained below under the heading "Additional
                  Selling Securityholders."

         The table below sets forth, as of June 30, 2003, the following
information for each selling securityholder:

         -        its name;

         -        the number of shares of common stock and of Series B preferred
                  stock beneficially



                  owned;

         -        the number of shares of common stock underlying currently
                  exercisable warrants and shares of Series B preferred stock
                  owned; and

         -        the number of shares of common stock and the Series B
                  preferred stock that may be offered and sold from time to time
                  under the prospectus.

         We cannot estimate the number of shares that the additional selling
securityholders will beneficially own after completion of this offering, because
the additional selling securityholders may sell all, part or none of their
shares of common stock or of Series B preferred stock under the prospectus and
because there are currently no agreements, arrangements or understandings with
respect to the sale of any of the shares offered by the prospectus. In addition,
the additional selling securityholders may have sold, transferred or otherwise
disposed of all or a part of their Series B preferred stock or common stock
since the date on which they provided the information regarding their beneficial
ownership.

         Each additional selling securityholder named below beneficially owns
less than one percent of the 6,043,469 shares of common stock and 7,000 shares
of Series B Preferred Stock outstanding on June 30, 2003. Unless otherwise
indicated below, to our knowledge, each selling securityholder named in the
table below has sole voting and investment power with respect to the securities
shown in the table, except as provided by applicable community property laws.
The information in the table below regarding beneficial ownership was furnished
to us by the additional selling securityholders. Beneficial ownership is
calculated based on Rule 13d-3 (d) (i) of the Securities Exchange Act of 1934.
In computing the number of shares of common stock and the percent of outstanding
shares beneficially owned by an additional selling securityholder, beneficial
ownership includes all shares of common stock issuable upon the exercise of
warrants and upon the conversion of Series B preferred stock. All warrants and
shares of Series B Preferred Stock were exercised and are convertible, as
applicable, as of June 30, 2003. These shares, however, are not included for
purposes of computing the beneficial ownership of any other additional selling
securityholder.

Retirement Trust


(1)      Includes shares of common stock that may be acquired upon the exercise
         of warrants and shares of common stock that may be acquired upon the
         conversion of shares of Series B preferred stock, in the amounts set
         forth in the table under the columns entitled "Shares of Common Stock
         Underlying Warrants/Series B Preferred." All warrants are currently
         exercisable for, and all shares of Series B preferred stock are
         currently convertible into, shares of common stock.

(2)      The number of shares of common stock issuable upon conversion of the
         Series B preferred stock, as shown in this table, is based upon the
         conversion rate of 422.72 shares of common stock per share of Series B
         preferred stock in effect as of April 29, 2003 (representing an
         adjustment of the initial conversion rate of 168.5374 shares of common
         stock for every share of Series B preferred stock due to adjustment
         events and accrued and unpaid dividends after the date of the
         prospectus), and includes accumulated and unpaid dividends through such
         date. This conversion rate will be subject to further adjustment as the
         result of any additional accumulated and unpaid dividends and other
         events contained in the terms of the Series B preferred stock, as
         described in the prospectus under "Description of the Series B
         Preferred Stock." If any adjustment event occurs, or if there is any
         change to accumulated and unpaid dividends on the Series B preferred
         stock, then the number of shares of common stock issuable upon
         conversion of the Series B preferred stock may increase or decrease in
         the future. Because the prospectus covers all shares issuable upon
         conversion of the Series B preferred stock, the actual number of shares
         of common stock offered under the prospectus may be greater than the
         number shown above in the table.

(3)      Except as described below, none of the selling securityholders has had
         any position, office or other material relationship with us or any of
         our affiliates within the past three years, other than as a result of
         the ownership of our shares or other securities. Information about the
         selling securityholders may change over time. Any changed information
         will be contained in one or more prospectus supplements.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ADEQUACY OR ACCURACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.


             The date of this prospectus supplement is July 2, 2003.
