Landis+Gyr to supply batteries for TEP energy storage project


Landis+Gyr is participating in an energy storage project in partnership with E.On Climate and Renewables and Tucson Electric Power.

E.On was one of two companies selected by TEP to provide capacity and availability from a 10 MW energy storage system.

Working with E. ON, the prime developer for the project, Landis+Gyr will supply a containerized Li ion energy storage system that integrates Toshiba's SCiB lithium titanate oxide batteries. The technology was chosen by Landis+Gyr because of its superior cycle life, high power density and rapid charge capabilities.

In total, TEP is adding 20 MW of energy storage capacity through two projects that will help balance load and regulate frequency on its distribution system, while also deferring capital investments in spinning reserves.

"The TEP storage project is driven by the growing need for rapid response to changes in energy supply and demand," said Mike Cooper, General Manager of Distributed Generation and Energy Storage solutions at Landis+Gyr. "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."

The storage facility and accompanying 2 MW solar array, located at the University of Arizona Science and Technology Park southeast of Tucson, is expected to be completed in the first quarter of 2017

The storage system will also help TEP study how to integrate a growing portfolio of renewable generating resources. The utility has a goal of generating 30 percent of its power from renewable resources by 2030, which amounts to about 1,200 MW. In the case of solar generation, storage systems can rapidly replace sudden losses of generation that occur throughout the day without overstressing slower ramping conventional generation.

Landis+Gyr's energy storage offering supports its broader Energy and Capacity Optimization System (ECOS), which combines communication, control and data management technologies into a flexible solution to monitor and manage the distribution network and enable optimal utilization of existing and new distributed energy resources. Capabilities include DC and AC storage solutions, distributed generation management software, solution design and application analysis along with 24/7 monitoring and maintenance services managed from its remote operating centers worldwide.
