E.ON combines battery and solar technologies for major customer in the US

E.ON will install and operate a ten megawatt battery to equalize the feed-in of renewable energy to the transmission network operated by US regional energy provider, Tucson Electric Power.

The battery will be charged by an associated solar park with a two megawatt capacity. E.ON will construct, own and operate the solar park.

This partnership with Tucson Electric Power is set to run for a period of ten years and is scheduled to begin in the first half of 2017. In the meantime, E.ON, in collaboration with Greensmith Power, a provider of storage solutions, will prepare a technical design and incorporate the battery, named the "Iron Horse", into the net. The battery will be located at the Science and Technology Park of the University of Arizona in Tucson.

The battery is based on lithium titanate technology, rendering it capable of handling rapid charging and discharging. In contrast to a conventional solution based on coal or gas, the battery offers the advantage of being able to react quickly to fluctuations in the network. In windy and sunny Arizona, this means that this E.ON system is able to provide the customer with even greater value.
