June 2 (Renewables Now) - E.on North America on Thursday opened its Iron Horse energy storage and solar project, a 10-MW/2.5-MWh storage facility and an accompanying 2-MW solar array, in Arizona.

The project, located at the University of Arizona's Tech Park in southeastern Tucson, will provide frequency regulation and voltage control support to Tucson Electric Power (TEP).                    

"We expect energy storage systems like Iron Horse to play an increasingly important role in the delivery of safe, reliable electric service to customers as we continue our expansion of renewable resources," said Carmine Tilghman of TEP. Currently, the power provider's large, community-scale solar resources generate enough electricity to serve over 52,000 customers.

Greensmith Energy was responsible for the design, integration and commissioning of the energy storage system, which uses lithium titanate oxide batteries.

This is the first energy storage project for E.on (ETR:EOAN) in North America. The company said it is applying lessons learned from it to its Texas Waves projects -- two projects at E.on's Pyron and Inadale wind farms in Texas. These projects are currently under construction and expected to be online by the end of 2017.
