Axion Power’s Energy Storage Systems Continue to Provide Value for Solar Installations


Axion Power International Inc. announces that their strategic partner, a solar installer based in New Jersey, has ordered four more PowerCube energy storage systems. This follows a previous order last November.

Energy storage is a promising solution to dealing with solar’s intermittency and high grid penetration, and according to GTM Research, is due for a huge rise in popularity in the next six years. The biggest barrier so far to making it more mainstream is the high cost, but now more companies are looking for new technologies and opportunities to make energy storage more widely distributed.

Axion Power International Inc., a company that develops lead-carbon PbC batteries and energy storage systems, has announced that their strategic partner, a solar installer in New Jersey for commercial and residential markets, has ordered four more PowerCube energy storage systems. The company had already used one in November of 2013, in combination with a solar installation. The Cubes will provide storage for the energy produced by a commercial solar panel system, and provide 500kw for the frequency regulation market on the PJM grid. The purchase order costs over $1,100,100, and includes batteries, racks, wiring, and a data communication system, plus all the electronics used to install them.


Axion Power Chairman and CEO Tom Granville stated that “Axion PowerCubes, with our proprietary PbC batteries and their unique properties that include high cycle life; high charge acceptance; an ability to recharge quickly (much faster than lithium-ion for example); and the battery’s inherent ability to equalize voltage in string applications, continue to prove their effectiveness and reliability, on a daily basis, in the energy storage and the frequency regulation markets.…We believe the PowerCube has shown it can be an effective part of any energy power distribution system and we plan to participate in opportunities such as those presented by initiatives in California and Hawaii.”
