Tucson Electric Power Company Key Developments

Tucson Electric Power Issues RFP for Construction of a 10 MW Renewable Energy Storage Facility

Tucson Electric Power has invited bids for the design and construction of a utility-scale energy storage system, which would enter into operations by the end of 2016. TEP issued a request for proposals (RFP) on April 24, 2015, seeking a project partner to build and own a 10 megawatt (MW) storage facility under a 10-year agreement. This systems can be used for storage of energy generated by renewable resources for later use, making them increasingly important for managing the local electric system without compromising reliability.

UniSource Energy Services Gains Efficient Energy Resource with Purchase of Natural Gas Generation

UniSource Energy Services has strengthened its generating portfolio and reduced its reliance on the wholesale energy market through the purchase of a share of the efficient natural gas-fired Gila River Power Station in Gila Bend. Under the terms of the purchase, its subsidiary UNS Electric, Inc. and sister company Tucson Electric Power (TEP) acquired the 550-megawatt (MW) Gila River Power Station Power Block 3 from Gila River Power LLC for USD 219 million. UNS Electric will control 137 MW of the unit's energy, while TEP will own the remaining output. The plant represents UES' first "base-load" power plant intended for near-continuous use. The company also owns natural gas-fired turbines with a combined capacity of 153 MW, but those units are designed to produce power only during periods of high demand, when UES' peak can exceed 450 MW. UES has traditionally purchased the majority of its power on the wholesale energy market at variable prices that reflect natural gas costs, regional energy demand and other market forces. Gila River Power Block 3 will reduce the need for such purchases. The plant is designed to operate throughout the year and is capable of meeting approximately one-third of UES electric customers' energy needs.
