Axion Power International, Inc., the developer of advanced lead-carbon PbC® batteries and energy storage systems, will supply an additional four PowerCube™ energy storage systems to provide storage for energy created by a commercial solar panel system. The systems will also service the frequency regulation market on the PJM grid.
PJM is a Regional Transmission Organization in the US and it forms part of the Eastern Interconnection grid which operates an electric transmission system serving over 58 million people in all or parts of 13 states.
PowerCube proves its reliability and effectiveness
The US$1,100,000 order came in from one of Axion Power’s strategic partners, a New Jersey-based solar installer for commercial and residential markets. The order includes batteries, racks, wiring, a data communication system and the electronics coordination required to outfit and install the PowerCubes.
Each of the PowerCubes will be tied to solar arrays that produce between 500kw and 700kw of power and the PowerCubes will each provide 500kw (both 500kw up and 500kw down) for frequency regulation.
Axion's onsite 500kw PowerCube has been connected into the PJM grid utility network for over two and a half years already.
Set up as a demand response and frequency regulation asset, the company developed a working model in a real world setting utilizing the PowerCube's ability to participate around the clock in the PJM frequency regulation market.
Axion’s strategic partner purchased its first PowerCube in November last year for use in combination with a solar installation.
According to Axion Power Chairman and CEO Tom Granville, the PowerCubes, with their 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.
Energy storage harnesses renewables’ potential
The storage of energy is being seen as a very important adjunct to renewable energy. In the past, renewable energy came online without energy storage but this has now changed in order to fully harness renewables’ potential.
A good example of this is in the state of California where, for example, an energy storage mandate has been introduced. The mandate requires that California utilities install 1325MW of new energy storage by 2020. Read our article, California’s Energy Storage Mandate-Will Others Follow?
Mr Granville says that the PowerCube has shown it can be an effective part of any energy power distribution system. He adds, “We plan to participate in opportunities such as those presented by initiatives in California and Hawaii.”
High growth for commercial solar markets
According to research, high growth is forecast for commercial solar markets as solar moves to take on supporting the data center and giving the enterprise a green image. A good example of this is Apple and Google. Read our article, Apple Generates its Own Power for Data Centres.
Brand is everything for the enterprise, the message of the company needs to resonate with customers and partners-Green is the way forward.
Solar is moving to provide a measurable supply of world energy and as penetration moves from .3% of the world energy supply to over 15% in five years, commercial uses of solar energy will represent a significant part of the growth.
Commercial solar energy certainly represents a measure of energy independence for the commercial sector. We cover this in our article, Energy Storage Sector Targets Commercial Customers and Drivers of the Commercial Energy Storage Market.
