Swiss smart metering firm Landis+Gyr is to supply a 10MW energy storage system to Tucson Electric Power (TEP), a utility in Southern Arizona.

Landis+Gyr is supplying E.ON Climate & Renewables (EC&R), an arm of the European utility, which is handling the construction of the TEP storage facility.

TEP struck long-term arrangements with EC&R and wholesale electricity supplier NextEra Energy last year to supply capacity and availability from two new 10MW energy storage systems, to help balance load and regulate frequency on its distribution system.

The Arizona Corporation Commission (ACC) approved the projects in May.

The EC&R storage facility, located at the University of Arizona Science and Technology Park southeast of Tucson, is accompanied by a 2MW solar array. It is expected to be completed in the first quarter of 2017.

Landis+Gyr is supplying a containerised Li ion energy storage system that integrates Toshiba’s SCiB lithium titanate oxide batteries.

Mike Cooper, general manager of distributed generation and energy storage at Landis+Gyr, said: “The TEP storage project is driven by the growing need for rapid response to changes in energy supply and demand. This battery solution will allow E.ON to provide a flexible, high availability service to TEP for maintaining high quality and reliable power delivery in its territory.”

TEP, with around 420,000 customers in Arizona, is looking at ways to integrate a growing portfolio of renewable generating resources, with a goal of generating 30% of its power, or 1,200MW, from renewable resources by 2030.
