Battery System Tested by PG&E

December 17, 2014 By Linda Hardesty

EosEos Energy Storage will demonstrate its grid-scale battery system at Pacific Gas & Electric’s (PG&E’s) Smart Grid Lab in San Ramon, Calif., with the support of a $2.1 million award from the California Energy Commission.

For the project, the company is also partnering with the Electric Power Research Institute (EPRI), Lawrence Berkeley National Lab, Stem and ETM Electromatic.

The Energy Commission gave Eos’ project the highest ranking among 28 competing proposals and awarded $2.1 million from a total funding pool of $6.3 million. The project was the only advanced battery storage system selected.

Eos’ energy storage system is designed specifically to meet the requirements of California’s utilities and industrial users at a price of $160 per kilowatt-hour.

PG&E’s Smart Grid Lab will install and test the AC energy storage system, which integrates Eos’ Aurora DC battery, ETM’s power electronics and Stem’s intelligent software, featuring real-time data analytics and controls. EPRI will provide program management and data validation services and coordinate safety, interconnection and system integration requirements. Berkeley Lab will use real-time grid simulation to characterize performance and quantify system benefits under dynamic load and renewable integration use cases.
