TEP is currently in the process of inspecting the unit to determine the extent of the problem. Although the length of the outage has not been determined, based on preliminary information, TEP currently expects Springerville Unit 2 to be out of service for three to six weeks. TEP has contracted to purchase replacement power in the market to meet its retail load requirements during the Springerville Unit 2 outage, which is estimated to increase costs by approximately $500,000 per day. TEP's retail rates are currently capped therefore none of these replacement power costs can be passed through to retail customers. The outage will also force TEP to incur additional operation and maintenance expenses to repair Springerville Unit 2 but specific dollar amounts cannot be estimated based on the information that is currently available. ITEM 7.01 - REGULATION FD DISCLOSURE. ------------------------------------- Although the total financial impact of the Springerville Unit 2 outage cannot be determined at this time, UniSource Energy Corporation (UniSource Energy) expects the costs of the outage to result in reduced 2005 full-year earnings. UniSource Energy is currently unable to determine whether 2005 full-year earnings will be within the previous range of $1.50 and $1.75 per basic share. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, each registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
