Tucson Electric Power to add fourth coal-fired unit at Springerville plant

摘要

A fourth unit will be added to Tucson Electric Power's Springerville generating station, expanding the availability of coal-fired power in the region. Salt River Project (SRP), a Phoenix-based utility, will own the 400-MW unit and control its output. The unit is expected to begin commercial operation in late 2009. The new unit will stand alongside Springerville Unit 3, which is under construction and is expected to be placed online during the third quarter of this year. That 400-MW unit will be leased from a financial owner by Tri-State Generation & Transmission Association, a wholesale power cooperative that will control the unit's output. Tucson Electric will operate both new units along with the two existing 380-MW units at SGS.
