Exhibit 99 UNISOURCE ENERGY NEWS FOR IMMEDIATE RELEASE						 July 30, 2003 Media Contact: Art McDonald, (520) 884-3628			 Page 1 of 6 Financial Analyst Contact: Jo Smith, (520) 884-3650 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. - MORE - UNISOURCE ENERGY REPORTS EARNINGS, REVISES OUTLOOK July 30, 2003 Page 2 of 6 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 - MORE - UNISOURCE ENERGY REPORTS EARNINGS, REVISES OUTLOOK July 30, 2003 Page 3 of 6 impact of FAS 143, UniSource Energy's consolidated year-to-date loss through June 2003 is $9.6 million, or $0.29 per share. TEP's year-to-date earnings through June 30, 2003, were $71.5 million, or $2.11 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 estimate range includes the $2.00 per share impact of adopting Financial Accounting Standard 143 (FAS 143). Numerous factors can affect UniSource Energy's ability to reach the 2003 estimate. The factors include, but are not limited to: ability of the company to reach financial closing of - MORE - UNISOURCE ENERGY REPORTS EARNINGS, REVISES OUTLOOK July 30, 2003 Page 4 of 6 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.
