(NYSE: UNS) today reported earnings for 2005 of $46 million, or $1.33 per basic share of common stock. UniSource Energy also announced that it expects the company's 2006 earnings will be between $1.65 and $2.05 per basic share. Growing retail and wholesale revenues and the benefits of a financial restructuring in 2005 were offset by the effects of maintenance and unplanned outages at generators serving Tucson Electric Power (TEP), UniSource Energy's largest subsidiary. A nearly four-week unplanned outage shut down Unit 2 at TEP's Springerville Generating Station (SGS) in August, a period when customer demand was high and energy prices were boosted by the impact of Gulf Coast hurricane activity. Higher gas prices and the cost of purchasing electricity during the outage contributed to an 82 percent increase in TEP's purchased power expense. "The cost of replacing the power that we lost to plant outages took a heavy toll on an otherwise solid year," said James S. Pignatelli, Chairman, President and CEO of UniSource Energy. "Our utility operations continued to experience strong customer growth, and we took advantage of the favorable capital markets to improve TEP's balance sheet, provide additional sources of liquidity and reduce interest costs." Both TEP and its sister utility, UniSource Energy Services (UES), maintained healthy customer growth rates and increased retail revenues in 2005. UES, which provides gas and electric service in northern and southern Arizona through subsidiaries UNS Gas and UNS Electric, reported earnings of $10 million in both 2005 and 2004. On a consolidated basis, UniSource Energy generated $276 million of cash flow from operations in 2005, allowing the company to internally fund capital expenditures of $203 million while increasing its dividend to shareholders. "I'm proud of our efforts to improve our long-term financial and operational performance," Pignatelli said. "We retired more than $320 million of debt and capital lease obligations at TEP, made capital investments to meet the needs of our growing electric and gas service areas and continued to fund the development of a new power plant." The new gas-fired Luna Energy Facility near Deming, N.M., is expected to be online during the first half of this year, providing TEP with 190 MW to help serve its retail and wholesale customers. TEP expects its total investment to be about $50 million when the plant is completed, all of which is being funded with internally generated cash. TEP will co-own the facility with PNM, an Albuquerque, N.M.-based utility and Phelps Dodge Energy Services. Meanwhile, construction of the new 400-MW coal-fired Unit 3 at SGS remains on pace for completion during the third quarter of 2006. TEP will operate the unit and purchase up to100 MW for a maximum of five years from Tri-State Generation and Transmission Association, which will lease the completed unit from a financial owner. In 2004, UniSource Energy reported earnings of $46 million, or $1.34 per basic share. Those results include $10 million of expenses related to a proposed acquisition of UniSource Energy that was rejected by state regulators in December 2004. TUCSON ELECTRIC POWER COMPANY TEP reported earnings for 2005 of $48 million, or $1.39 per basic UniSource Energy share, compared with earnings of $46 million, or $1.34 per basic UniSource Energy share, in 2004. Factors impacting TEP's 2005 results include: -- a $28 million increase in retail revenues due to warmer weather and the expansion of TEP's customer base, which grew to approximately 385,000 by the end of 2005 - a 3 percent increase from the same period last year, and an $18 million increase in wholesale revenues due to higher market prices for energy. -- $74 million of higher purchased power and fuel expense, leading to a $28 million decline in utility gross margin (the sum of retail and wholesale electric revenues, less fuel and purchased power expense). The increase in purchased power expense was due to planned and unplanned coal plant outages, as well as higher market prices for energy; -- a $6 million increase in amortization expense of the Transition Recovery Asset; -- a $17 million reduction in interest expense due to the debt refinancing completed in 2005 and lower balances on capital lease obligations; and -- a $10 million increase in gains from the sales of excess sulfur dioxide (SO2) emission allowances. In 2004, TEP recorded $8 million of expenses related to its allocation of costs associated with a proposed acquisition of UniSource Energy. UNS GAS UNS Gas reported net income for 2005 of $5 million, compared with net income of $6 million in 2004. Retail therm sales in 2005 declined by 2 percent compared to 2004 due to warmer weather in northern Arizona. UNS Gas' retail customer base grew to approximately 139,000 by the end of 2005, a 4 percent increase from the previous year. UNS ELECTRIC UNS Electric reported earnings for 2005 of $5 million, compared with earnings of $4 million in 2004. Warmer weather and customer growth contributed to a 4 percent year-over-year increase in retail kilowatt hour sales. UNS Electric's customer base grew to approximately 89,000 customers, a 4 percent increase over 2004. MILLENNIUM ENERGY HOLDINGS Millennium Energy Holdings, a subsidiary that oversees UniSource Energy's unregulated investments, reported a net loss of $6 million in 2005, compared with a net loss of $4 million in 2004. Higher net losses in 2005 are due primarily to increased operating expenses at some of its investees and a $1 million net loss on the disposal of Microsat.

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 currently estimates that its 2006 full-year earnings will be between $1.65 and $2.05 per share. Numerous factors can affect UniSource Energy's ability to reach the 2006 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 regional economy; fuel and purchased power expense; changes to long-term contracts; changes in asset depreciable lives; the potential sale of Global Solar; and the amount of losses incurred by Millennium. UniSource Energy's earnings are subject to the seasonal energy sales of its utilities. Generally, TEP records a significant portion of its earnings during the third quarter as a result of peak energy usage during the summer. DISCUSSION OF 2005 EARNINGS AND 2006 OUTLOOK UniSource Energy officials will discuss the company's 2005 year-end earnings and outlook for 2006 on March 3, 2006 beginning at 12 p.m. EST in a conference call that will be available live on the Internet.
