UNISOURCE ENERGY REPORTS EARNINGS FOR SECOND QUARTER OF 2003,
REVISES EARNINGS OUTLOOK FOR REMAINDER OF YEAR

TUCSON, ARIZ. - UniSource Energy Corporation (NYSE:UNS) reported net income for
the second quarter of 2003 of $4.6 million, or $0.14 per share of common stock.
UniSource Energy also updated its estimated range for 2003 full year earnings
from $3.10 to $3.30 per share to $2.90 to $3.20 per share.

Quarterly net income was down $7.3 million, or 61 percent, from the second
quarter of 2002. The reduction was caused primarily by lower retail kilowatt
hour (kWh) sales due to moderate weather, decreased wholesale kWh sales, higher
gas prices and the purchase of replacement energy due to unplanned outages at
power plants owned by Tucson Electric Power Company (TEP), UniSource Energy's
principal subsidiary.

"I'm disappointed by our second quarter performance," said James S. Pignatelli,
Chairman, President and CEO of UniSource Energy. "We were significantly affected
by extended power plant outages, and milder weather eroded our energy sales
despite the continuing growth of TEP's customer base."

Temperatures in TEP's service territory during the second quarter of 2003 fell
short of last year's higher-than-normal levels. The resulting decline of 2.9
percent in cooling degree days contributed to a $1.6 million reduction in retail
revenues between the second quarters of 2003 and 2002.

To help meet the energy needs of its retail customers, TEP spent an additional
$2.5 million in the second quarter of 2003 to replace energy lost to unplanned
outages at coal-fired generators. Those outages also resulted in lost wholesale
market opportunities totaling an estimated $3.5 million in the second quarter.

"Our coal-fired generating stations have outstanding track records for
reliability, so these outages were unusual," Pignatelli said.

TEP's wholesale kWh sales decreased by 38 percent in the second quarter of 2003,
compared with the same period in 2002. Unplanned generation outages left TEP, at
times, unable to capitalize on average around-the-clock energy prices that
increased to $39 per megawatt hour (MWh) during the second quarter of 2003 from
$24 per MWh during the same period in 2002.

TEP's customer base continued its strong growth during the second quarter of
2003. The utility's average number of retail customers increased by 2.3 percent
to 362,375 between the second quarters of 2002 and 2003.

UniSource Energy made progress during the second quarter of 2003 toward the
planned acquisition of Arizona gas and electric system assets from Citizens
Communications (NYSE: CZN). The Arizona Corporation Commission endorsed the
proposed purchase and approved rate increases for both gas and electric
customers. The acquisition is now expected to be finalized August 11.

Tucson Electric Power Company
- -----------------------------

TEP reported net income of $11.2 million, or $0.33 per UniSource Energy share,
in the second quarter of 2003, compared to $17.5 million, or $0.52 per
UniSource Energy share, in the second quarter of 2002.

The difference was due primarily to decreased retail kWh sales, higher gas
prices as well as power plant outages that required TEP to purchase replacement
power and limited its ability to sell power on the wholesale market.

TEP's retail kWh sales were down 1.4 percent in the second quarter of 2003
compared to the same period last year.  Total retail revenues were $173 million
in the second quarter of 2003, down approximately 1 percent from the second
quarter of 2002. Sales volumes to residential and commercial customers increased
slightly in the second quarter of 2003 compared to the second quarter of 2002.
Sales to industrial customers declined 4.2 percent quarter to quarter.

Wholesale revenues fell to $35.5 million in the second quarter of 2003 from
$49.2 million in the second quarter of 2002. Other factors affecting results in
the second quarter of 2003 included increased interest expense and higher
operating and maintenance costs.

Millennium Energy Holdings (MEH)
- --------------------------------

MEH lost $4.4 million, or $0.13 per UniSource Energy share, during the second
quarter of 2003, matching its losses from the second quarter of 2002. The loss
in the second quarter of 2003 was due, in part, to ongoing operating expenses at
Global Solar Energy and Infinite Power Solutions as well as from discontinued
subsidiaries.

Year-to-Date
- ------------

UniSource Energy's consolidated year-to-date earnings through June 30, 2003, are
$57.9 million, or $1.71 per share, compared to $5.6 million, or $0.17 per share,
during the same period last year.

This year's results reflect the adoption of Financial Accounting Standard 143
(FAS 143), a new rule related to accounting for plant retirement and removal
costs. The company recorded a $67.5 million after-tax gain as a result of
adopting FAS 143.  Excluding the

impact of FAS 143, UniSource Energy's consolidated year-to-date loss through

per UniSource Energy share, compared to $15.5 million, or $0.46 per UniSource
Energy share. Excluding the impact of FAS 143, TEP's year-to-date earnings
through June 30, 2003, are $4.0 million, or $0.11 per UniSource Energy share.

MEH's year-to-date loss through June 30, 2003, was $9.4 million, or $0.28 per
UniSource Energy share, compared to $7.7 million, or $0.23 per UniSource Energy
share, in 2002.

the Springerville Unit No. 3 expansion project and the recognition of a related
development fee; impacts from the Citizens' utility transaction; 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 accounting standards; and the amount of research,
development and operating expenses incurred by UniSource Energy's unregulated
energy technology investments.

UniSource Energy's earnings are subject to TEP's 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. Conversely, TEP
generally records a loss during the first quarter due to moderate temperatures
and lower customer demand.
