Additional information

Tucson Electric Power (TEP) has entered into long-term agreements with E.ON Climate & Renewables and NextEra Energy Resources for the construction of two 10 MW energy storage systems. The systems will help maintain the required balance between energy demand and supply while satisfying other energy management requirements.The systems also can help prevent power outages during periods of high energy demand by supporting stable voltage on TEP’s energy delivery system. In the event of an outage, the systems could provide about 5 MW of power for up to an hour. Use of these energy storage systems will help TEP avoid using more expensive generating resources for system disturbances. They also will allow the company to defer costly investments in other system infrastructure.
