Performing renewable integration for the site

WESTBOROUGH, Mass.--A123 Energy Solutions announced the commissioning of a 500-kilowatt Grid Storage Solution (GSS™) for Dongfang Electric Machinery Co., Ltd, one of the largest manufacturers of power generating equipment in China. The 500kW, 125kWh GSS is connected to the microgrid at Dongfang Electric Machinery Co's Hangzhou facility and will be performing renewable integration for the site, where it is co-located with wind, PV, and conventional generation resources. This energy storage installation, A123 Energy's second deployment in China, is a High Rate (HR) GSS and is not containerized, but instead is housed in one of the site's existing buildings.

"For this project, we needed to install energy storage in an existing building. The flexibility of our GSS allowed us to accomplish just that, with no major modifications or special considerations around the building," said Bud Collins, President of A123 Energy Solutions. "In addition, our AEROS™ control software, developed solely by A123 Energy, allows our customer to use the storage system to manage its renewable and conventional generation, optimizing energy usage for the site."

The HR GSS is well suited for accommodating fluctuations in variable energy resources like wind or solar, and can be used to improve the efficiency of traditional thermal generators as well. Operating worldwide in revenue service since 2009, the HR GSS forms the bulk of the grid energy storage that A123 Energy Solutions has deployed to date, and performs in a variety of applications including frequency regulation, reserve, ramp management, and T&D support.
