              UNISOURCE ENERGY REPORTS THIRD QUARTER 2004 EARNINGS


TUCSON, ARIZ. - UniSource Energy Corporation (NYSE: UNS) reported earnings today
for the third quarter of 2004 of $24 million, or $0.69 per share of common
stock. UniSource Energy reported earnings of $27 million, or $0.81 per share, in
the third quarter of 2003, as restated.

Milder summer weather, increased Transition Recovery Asset amortization,
acquisition-related expenses and costs associated with Sarbanes-Oxley Section
404 compliance contributed to the decrease in quarterly earnings.

"We anticipated these higher operating costs and our utilities are performing in
line with expectations." said James S. Pignatelli, Chairman, President and CEO
of UniSource Energy and its principal subsidiary, Tucson Electric Power Company
(TEP).

UniSource Energy Services (UES), a subsidiary that began providing natural gas
and electricity in northern and southern Arizona on August 11, 2003, contributed
$0.4 million to third quarter earnings.

Higher operating costs during the third quarter were partially offset by lower
interest expense and a lower net loss at Millennium Energy Holdings (MEH). MEH,
which oversees UniSource Energy's unregulated investments, reported a net loss
of $1 million in the third quarter of 2004, compared with a net loss of $3
million in the same period last year.

In November 2003, UniSource Energy entered into an agreement that provides for
the acquisition of all of the company's outstanding common stock for $25.25 per
share by Saguaro Utility Group L.P., an Arizona limited partnership whose
general partner is Sage Mountain, L.L.C. and whose limited partners include
investment funds affiliated with Kohlberg Kravis Roberts & Co., L.P., J.P.
Morgan Partners, LLC, and Wachovia Capital Partners.

On March 29, 2004, UniSource Energy's shareholders voted to approve the
acquisition agreement. The requirements under the Hart-Scott-Rodino Act were
satisfied on March 19, 2004. On October 12, 2004, the Federal Energy Regulatory
Commission issued an order approving the proposed acquisition. The acquisition
still requires approval by the Arizona Corporation Commission and the Securities
and Exchange Commission under the Public Utility Holding Company Act. The
acquisition is now expected to occur prior to the end of the first quarter of
2005.

TUCSON ELECTRIC POWER COMPANY

TEP reported third quarter 2004 earnings of $26 million, or $0.76 per UniSource
Energy share, compared with restated earnings of $32 million, or $0.95 per
UniSource Energy share, in the same period last year.

TEP's utility gross margin (the sum of electric retail and wholesale revenues
less fuel and purchased power expenses) did not change from the third quarter of
2003. TEP's customer base grew by 2 percent to 372,899 between the third
quarters of 2003 and 2004.

Sales to residential customers of TEP fell 2 percent from the third quarter of
2003 due to a 15 percent decrease in cooling degree days. Sales to commercial
and mining customers increased 4 and 14 percent, respectively, over the same
period last year.

Other factors affecting TEP's third quarter earnings include a $5 million
increase in Transition Recovery Asset amortization and a $3 million decline in
total interest expense resulting from lower rates under TEP's credit agreement
and lower capital lease obligation balances compared with last year.


UNISOURCE ENERGY SERVICES


UES reported earnings of $0.4 million, or $0.01 per UniSource Energy share,
during the third quarter of 2004. During the third quarter of 2004, UNS Electric
recorded retail revenues of $45 million, while UNS Gas produced retail revenues
of $16 million.

Customer growth at UES remains strong. Since the third quarter of 2003, UNS Gas'
retail customer base grew by 2 percent and UNS Electric's retail customer bases
grew by more than 4 percent.

YEAR-TO-DATE

UniSource Energy's consolidated year-to-date earnings through September 30,
2004, were $43 million, or $1.25 per share, compared to $87 million, or $2.56
per share, during the same period last year as restated.

Last year's results reflected the adoption of Financial Accounting Standard 143
(FAS 143), a new rule related to accounting for asset retirement and removal
costs. Excluding the impact of FAS 143, UniSource Energy's consolidated
year-to-date restated earnings through September 2003 were $19 million, or $0.56
per share.

(1) UniSource Energy Services began operations on August 11, 2003.

(2) TEP results in the first nine months of 2003 include an after-tax gain of
    $67 million for the Cumulative Effect of Accounting Change related to the
    adoption of FAS 143.

(3) During the second quarter of 2004, TEP determined that its methodology for
    estimating unbilled revenues resulted in an under reporting of revenues in
    prior periods. As a result, TEP adopted a new methodology for estimating
    unbilled revenues and restated prior period financial statement.

UniSource Energy believes that the presentation of TEP, UES and MEH net income
or loss on a per UniSource Energy share basis, which are non-GAAP financial
measures, provides useful information to investors by disclosing the results of
operations of its business segments on a basis consistent with UniSource
Energy's reported earnings.


EARNINGS OUTLOOK


UniSource Energy's management has reaffirmed its 2004 full-year earnings
estimate of $1.25 to $1.60 per share.

Numerous factors can affect UniSource Energy's ability to reach the 2004
estimates. The factors include, but are not limited to: uncertainties prevailing
in the wholesale power market; regulatory decisions; performance of TEP's
generating plants; the weather; the pace and strength of the economic recovery
in the region; fuel and purchased power expense; changes to long-term contracts;
changes in asset depreciable lives; changes in accounting standards; the amount
of research, development and operating expenses incurred by UniSource Energy's
unregulated

energy technology investments; acquisition related costs and our
compliance with the restrictive covenants contained in the acquisition
agreement.

UniSource Energy's earnings are subject to its utilities' seasonal energy sales.
Generally, TEP records a significant portion of its earnings during the third
quarter as a result of peak energy usage during the summer.
