Axion Power wins order for energy storage systems

Axion Power International the developer of advanced lead-carbon PbC batteries and energy storage systems, won purchase order for four more PowerCube energy storage systems from its strategic partner, a NJ-based solar installer for commercial and residential markets.

The cubes will provide storage for energy created by a commercial solar panel system and service the frequency regulation market on the PJM grid.

The purchase order — valued at about $1.1 million— includes batteries, racks, wiring, a data communication system and the electronics coordination needed to outfit and install the PowerCubes.

Each of the PowerCubes will be tied to solar arrays that produce between 500 kW and 700 kW of power and the PowerCubes will each provide 500 kW (both 500 kW up and 500 kW down) for frequency regulation.

Axion’s onsite 500 kW PowerCube has been connected into the PJM grid utility network, the nation’s largest power transmission organization serving more than 58 million people in all or parts of 13 states, for more than 2 years. Set up as a demand response and frequency regulation asset, the company developed and tweaked a working model in a real world setting using the PowerCube’s ability to participate 24/7 (although Axion’s model shows the ideal return at a lesser number than 24/7) in the PJM frequency regulation market.
