E.ON completes 10 MW energy storage system in Arizona

E.ON Climate and Renewables has completed a 10 MW lithium titanium oxide storage facility at the University of Arizona´s Science and Technology Park. The so-called Iron Horse Battery Energy Storage Project integrates a new 2 MW solar array, and will provide frequency response as well as voltage control, according to a press release from E.ON.

Partner company Tucson Electric Power (TEP) will use the faciltiy to maintain reliable electricity for more than 400,000 customers.

Battery manufacturer Landis+Gyr said that it designed, engineered, and supplied the storage system for this project, based on Toshiba’s SCiB™ technology.

Another partner firm, Greensmith, provided software that leveraged the batteries suitable for high frequency, high power applications. The company states that its GEMS software control platform will deliver real-time monitoring, integrated control, system optimization and safety throughout life.

“We expect energy storage systems like Iron Horse to play an increasingly important role in the delivery of safe, reliable service to customers as we continue our expansion of renewable resources,” said Carmine Tilghman, Senior Director of Energy Supply and Renewable Energy for TEP.

According to E.ON, experience gained during the Iron Horse project is now being used in Eon´s Texas Wave projects, the second and third grid connected lithium-ion battery systems installed by E.ON in North America.

In May, Greensmith announced that Finnish provider of energy solution, Wärtsilä, signed an agreement to acquire the company. The transaction, yet to be confirmed by U.S. regulatory authorities, is expected to close by July 2017.
