Item 5.  Other Events
- ---------------------

  NEW ENERGY VENTURES, INC. SALE
  ------------------------------

  On  June  18,  1999,  UniSource Energy Corporation  ("UniSource
Energy")   announced  that  its  wholly-owned   subsidiary,   MEH
Corporation  ("MEH"),  and  New Energy Holdings,  L.L.C.  ("NEH")
entered  into  an  agreement to sell New  Energy  Ventures,  Inc.
("NEV")  to AES Corporation ("AES").  MEH and NEH each  currently
own 50% of NEV.  NEH is owned by the senior management of NEV.

   Under the terms of the sale, which is expected to close in the
third  quarter of 1999, MEH will receive $50 million  as  follows
(all values are approximate):

     -- $27.2 million in AES common stock at closing.  The number and
        total  value of shares received at closing is subject  to
        adjustment depending on the price of AES stock on the New York
        Stock Exchange.  AES has agreed to register the stock shortly
        after closing.

     -- Promissory notes issued by NEV totaling $22.8 million.  The
        notes will be secured, bear interest at 9.5%, and $11.4 million
        of principal is due 12 months after closing and the remaining
        $11.4 million is due 24 months after closing.

  As  part  of  the agreement, AES will repay a $10 million  loan
NEV  obtained  from  an unrelated party that  was  guaranteed  by
UniSource  Energy.  Also, UniSource Energy has been the guarantor
of performance bonds and other guarantees that secure amounts NEV
owes  to  utility distribution companies and energy suppliers  in
connection with NEV's sales to retail electric customers.   These
credit  commitments are secured and will remain in place  for  at
least  120 days from June 18, 1999.  The UniSource Energy  credit
commitments  will be terminated as the guarantees  expire  or earlier
as substitute guarantors are provided by NEV or AES.  See Loans  and
Guarantees,  Investing And Financing Activities  in  Management's
Discussion  and  Analysis of Financial Condition and  Results  of
Operations  in the Quarterly Report on Form 10-Q for  the  period
ended March 31, 1999 for additional information.

  Prior  to  the  closing, AES has agreed to  extend  up  to  $25
million in credit for the benefit of NEV.  Amounts extended under
that  facility  will  be  guaranteed by MEH  and  NEH  until  the
closing,  at which time the guarantees will terminate.  AES  will
also  provide, prior to closing, additional guarantees as  needed
to support NEV's business activities.  If the transaction has not
closed  by December 31, 1999, NEV and/or UniSource Energy,  or  a
third party will assume or replace these additional guarantees.

  The   sale  is  subject  to  approval  by  the  Federal  Energy
Regulatory  Commission  (FERC), clearance under  the  Hart-Scott-
Rodino Anti-trust Act, and various standard terms and conditions.

  UniSource  Energy  expects  to  recognize  a  pre-tax  gain  of
approximately $30 million on the transaction over  the  next  two
years.   The  timing  of the recognition  of  the  gain  will  be
determined at closing.



   NEV, formed in 1995 and headquartered in Los Angeles, provides
electricity  and  energy products and services  to  customers  in
deregulating energy markets.  AES, based in Arlington,  Virginia,
is a global power company that owns, or has an interest in, power
facilities in the United States and overseas.

   On June 21, 1999 the Governor appointed Mr. William A. Mundell

Commissioner by the Arizona Supreme Court on June 9,  1999.   Mr.
Mundell will serve until the general election in 2000.
