Exhibit 99 UNISOURCE ENERGY NEWS FOR IMMEDIATE RELEASE October 23, 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 THIRD QUARTER OF 2003 Tucson, Ariz. - UniSource Energy Corporation (NYSE: UNS) reported net income for the third quarter of 2003 of $26.7 million, or $0.79 per share of common stock. Reported quarterly net income increased $3.9 million, or 17 percent, over the same period last year. The increase is due in part to a 7 percent rise in retail revenues at Tucson Electric Power (TEP), UniSource Energy's principal subsidiary. "We provided our growing customer base with record levels of power during a hot summer, bolstering our earnings and providing our customers with the high level of reliable service they've come to expect," said James S. Pignatelli, Chairman, President and CEO of UniSource Energy. Warmer temperatures and the continuing growth of TEP's customer base during the third quarter of 2003 led to a 7 percent increase in retail kWh sales over the same period last year. Higher energy use by its retail customers left the utility with less power to sell, leading to a 38 percent reduction in wholesale kWh sales compared to the third quarter of 2002. Unplanned plant outages also had a greater impact on earnings this past quarter compared to the same period last year. Last year's results included an $11.3 million coal contract termination fee at TEP and various tax benefits of $4.8 million. UniSource Energy's interest expense rose $4.2 million in the third quarter of 2003 compared to the same period last year. The increase was driven by higher debt facility costs at TEP and the cost of financing used to purchase Arizona gas and electric system assets from Citizens Communications Company (NYSE: CZN) on Aug. 11, 2003. UniSource Energy Services (UES), a new subsidiary formed to run the systems acquired from Citizens, was slightly accretive to third quarter earnings during less than two months of operations. "The transition from Citizens to UES has gone very smoothly," Pignatelli said, "and we're looking forward to solid performance from UES for years to come." TUCSON ELECTRIC POWER COMPANY TEP reported net income of $31.5 million, or $0.93 per UniSource Energy share, in the third quarter of 2003, compared to $26.6 million, or $0.79 per UniSource Energy share, in the third quarter of 2002. Total retail revenues reached $229.7 million during the third quarter of 2003, a 7 percent increase over the same quarter last year. Sales volumes to residential and commercial - MORE - UNISOURCE ENERGY REPORTS EARNINGS October 23, 2003 Page 2 of 6 customers increased by 10 percent and 8 percent, respectively, compared to last year. Sales to industrial and mining customers increased a combined 2 percent during the quarter compared to the same period last year. Cooling degree days in TEP's service territory increased 9 percent over the third quarter of 2002. The utility's growing customer base also contributed to increased sales. TEP's average number of retail customers reached 364,363 in the third quarter of 2003, a 2 percent increase over the third quarter of 2002. Wholesale revenues fell to $32 million, a 22 percent reduction from the third quarter of 2002. The combined cost of fuel and purchased power in the third quarter of 2003 increased $5 million, or 6 percent, over the same period last year. The average around the clock price of wholesale power on the Dow Jones Palo Verde Index was $46 per megawatt hour (MWh) during the third quarter of 2003, up from $28 per MWh during the same period last year. The average cost of natural gas, meanwhile, rose 76 percent between those two periods. UNISOURCE ENERGY SERVICES UES reported net income of $0.1 million in the third quarter of 2003. Third quarter results include operations from Aug. 11, 2003, through the end of the quarter. Total revenues from UES electric operations reached $23.7 million during the third quarter of 2003. Total revenues from UES gas operations reached $10.3 million during the third quarter, including $6.2 million in retail sales and $3.8 million in contracted supply agreements. MILLENNIUM ENERGY HOLDINGS (MEH) MEH reported a $2.7 million loss, or $0.08 per UniSource Energy share, in the third quarter of 2003, compared to $2.8 million in losses, or $0.08 per UniSource Energy share, in the same period last year. Losses last year were reduced by a $1.5 million tax benefit. Global Solar Energy reported a $1.5 million loss during the quarter, an improvement over the $3.3 million loss during the same quarter last year. Losses at Infinite Power Solutions were $0.4 million in the third quarter of 2003 compared to $0.8 million during the same period last year. Operating expenses at other subsidiaries offset modest earnings recorded by Southwest Energy Solutions and Millennium Environmental Group. YEAR TO DATE UniSource Energy's consolidated year-to-date earnings through Sep. 30, 2003, were $84.5 million, or $2.50 per share, compared to $28.4 million, or $0.84 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 earnings through Sep. 30, 2003, were $17.0 million, or $0.50 per share. - MORE - UNISOURCE ENERGY REPORTS EARNINGS October 23, 2003 Page 3 of 6 TEP's year-to-date earnings through Sep. 30, 2003, were $103.0 million, or $3.05 per UniSource Energy share, compared to $42.1 million, or $1.25 per UniSource Energy share, during the same period last year. Excluding the impact of FAS 143, TEP's year-to-date earnings through Sep. 30, 2003, were $35.5 million, or $1.05 per UniSource Energy share. MEH's year-to-date loss through Sep. 30, 2003, was $12.1 million, or $0.36 per UniSource Energy share, compared to $10.5 million, or $0.31 per UniSource Energy share, during the same period last year.

UniSource Energy management currently estimates that its 2004 full- year earnings will be between $1.25 to 1.60 per share. Numerous factors can affect UniSource Energy's ability to reach the 2003 and 2004 estimates. The factors include, but are not limited to: uncertainties prevailing in the - MORE - UNISOURCE ENERGY REPORTS EARNINGS October 23, 2003 Page 4 of 6 wholesale power market; regulatory decisions; performance of TEP's generating plants; the ability to recognize a development fee related to the construction of Springerville Generating Station Unit 3; 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 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. Conversely, TEP generally records a loss during the first quarter due to moderate temperatures and lower customer demand.
