With a request for proposals, TEP is seeking a project partner to build and own a 10 MW storage facility under a 10-year agreement. Such systems can be used to store energy generated by renewable energy resources for later use, making them increasingly important for managing the local electric system without compromising reliability.
The RFP process is being managed by New Hampshire-based Accion Group.
Solar power plays an important part in TEP’s increasingly diverse generating portfolio. The company has plans to reduce its overall coal generation capacity by more than 30 percent over the next five years by increasing use of renewable power, energy efficiency and natural-gas generation. TEP has about 330 MW of total renewable generating capacity, enough to meet the electric needs of about 70,000 homes.
TEP provides electric service to more than 414,000 customers in southern Arizona.
