E.ON Climate & Renewables North America LLC has signed an agreement with utility Tucson Electric Power (TEP) to provide frequency response and voltage control from a grid-scale, 10 MW battery energy storage facility with a 2 MW solar array.
The Iron Horse Battery Energy Storage Project will be located adjacent to the University of Arizona Science and Technology Park southeast of Tucson. The project is expected to be completed in the first half of 2017.
“TEP is the perfect partner for this project, as they are an experienced utility operator and very interested in integrating innovative, cost-effective technologies for the benefit of their customers,” says Mark Frigo, E.ON’s vice president of energy storage in North America.
Carmine Tilghman, a TEP senior director who oversees the company’s renewable energy programs, explains, “We’re working very hard to build a more resilient grid in a cost-effective way for our customers, and exploring energy storage technologies is an important aspect of our efforts.”
E.ON, in partnership with Greensmith Energy, says it will design and integrate a customized energy storage solution for TEP that is capable of providing the benefits of a conventional generation system’s availability and response capabilities. The project will enhance TEP’s contribution to grid stability by providing ancillary services during the 10-year contract period.
“The system will be capable of responding faster than conventional generation to adjust to rapid changes in power demand,” adds Frigo.
In addition to supplementing TEP’s grid management, E.ON says it also provides energy to the utility from its 6.6 MW Tech Park Solar and 13.2 MW Valencia Solar facilities and partnered on the turnkey construction of TEP’s 17.2 MW solar facility at the Fort Huachuca Army Base near Sierra Vista, Ariz.
