            UNISOURCE ENERGY REPORTS THIRD QUARTER EARNINGS FOR 2005

Tucson, Ariz. - UniSource Energy Corp. (NYSE: UNS) today reported earnings for 
the third quarter of 2005 of $18.4 million, or $0.53 per basic share of common 
stock. For the same period in 2004, UniSource Energy reported earnings of $23.8
million, or $0.69 per share.

The unplanned, four-week outage of a 380-megawatt generator serving Tucson
Electric Power (TEP), UniSource Energy's largest subsidiary, and charges related
to mark-to-market adjustments on forward energy sales contributed to lower
earnings this past quarter.

The outage of Unit 2 at TEP's coal-fired Springerville Generating Station (SGS)
reduced TEP's utility gross margin (the sum of retail and wholesale electric
revenues less fuel and purchased power expense) by $14 million due to
replacement power costs and lost wholesale sales opportunities.

"The outage occurred during a period of high energy use by TEP customers, so our
replacement power costs were significant," said James S. Pignatelli, Chairman,
President and CEO of UniSource Energy.

"We've fully repaired the damage and addressed the control system malfunction
that caused it," Pignatelli said. "So we're well positioned to take advantage of
higher market power prices by capitalizing on wholesale sales opportunities at a
time when moderate weather leads to lower energy use by TEP's retail customers."

TEP's pre-tax unrealized losses increased $8 million due to forward energy sales
made before Gulf Coast hurricanes drove up wholesale power prices. Because those
contracts are now priced below market, TEP recorded a negative mark-to-market
adjustment. This adjustment will be reversed when TEP delivers that energy in
the fourth quarter of 2005 and the first six months of 2006.

UniSource Energy Services, which provides gas and electric service in northern
and southern Arizona through subsidiaries UNS Gas and UNS Electric, reported
earnings of $0.2 million during the third quarter of 2005, compared to earnings
of $0.4 million from the same period last year.





TUCSON ELECTRIC POWER COMPANY

TEP reported earnings for the third quarter of 2005 of $20.4 million, or $0.58
per basic UniSource Energy share, compared with earnings of $26.2 million, or
$0.76 per basic share, during the same period last year.

Factors impacting TEP's third quarter 2005 results include:

-        a $16.2 million increase in retail revenues due to warmer weather and
         the expansion of TEP's customer base, which grew to 382,325 by the end
         of the third quarter - a 3 percent increase from the same period last
         year. Those gains were offset by higher replacement power costs and
         unrealized losses recorded on forward energy sales, leading to a $27.1
         million decline in utility gross margin;

-        a $5.6 million reduction in interest expense due to a financial 
         restructuring completed earlier this year; and

-        a $4.2 million gain from the sale of excess sulfur dioxide (SO2) 
         emissions allowances.

Other factors affecting TEP's third quarter earnings include lower depreciation
expense resulting from the extension of depreciation lives of various generation
assets as of July 2004 and April 2005, and higher expenses related to
amortization of the Transition Recovery Asset (TRA).


UNS GAS

UNS Gas reported a net loss in the third quarter of 2005 of $2.1 million,
compared with a net loss of $1.8 million during the same period last year.

Retail therm sales for the quarter decreased 1.2 percent over last year due to
warmer weather in northern Arizona. UNS Gas' retail customer base grew to
136,207 by the end of the third quarter, a 4.4 percent increase from the same
period last year.


UNS ELECTRIC

UNS Electric reported earnings for the third quarter of 2005 of $2.3 million,
compared with earnings of $2.2 million for the third quarter of 2004.

Warmer weather and customer growth led to a 6 percent increase in kilowatt hour
sales compared with the same period last year. UNS Electric's customer base grew
to 88,362 customers, a 4.9 percent increase over the same period last year.


MILLENNIUM ENERGY HOLDINGS

Millennium Energy Holdings, a subsidiary that oversees UniSource Energy's
unregulated investments, reported a net loss of $0.4 million during this past
quarter, compared with a loss of $1.4 million from the same period last year.





YEAR TO DATE

UniSource Energy's consolidated year-to-date earnings through September 30, 2005
were $24.1 million, or $0.69 per basic share of common stock. During the same
period last year, UniSource Energy reported earnings of $43.0 million, or $1.25
per basic share.

UniSource Energy believes that the presentation of TEP, UNS Gas, UNS Electric,
Millennium, and Other segment net income or loss on a per basic 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 reaffirms its estimate given on Sept. 8, 2005,
that 2005 full-year earnings will be between $1.30 and $1.60 per basic share.

Numerous factors can affect UniSource Energy's ability to reach the 2005 
estimate. The factors include, but are not limited to: changes in accounting 
standards; 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; and the amount of losses incurred
by Millennium.

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.
