Located in Beijing, this is A123 Energy Solutions’ first deployment in China in commercial operation. The containerized 53-foot long battery is one of A123’s widely deployed High Rate (HR) Grid Storage Solutions and stabilizes the grid to ensure power quality.

The 2MW HR Grid Storage Solution, a high-power battery based on A123’s proprietary Nanophosphate chemistry, is suited for the rapidly changing power profiles of frequency regulation service, and able to serve dual duty as both a controllable 2MW load as well as a 2MW generator—in essence providing 4MW of ramping capability.

Deployed worldwide in revenue service since 2009, the HR Grid Storage Solution forms the bulk of the grid energy storage product line that A123 Energy Solutions has delivered to date.

This 2MW Ray Power installation is our first in China, but with our experience installing grid energy storage systems successfully all around the world, working with Ray Power we were able to commission the unit in just under four weeks from site readiness. The HR is one of our most mature products and we look forward to installing additional systems with Ray Power to perform frequency regulation, frequency response, or other rapidly ramping high power applications.
