By Greentech Lead Team: Electrovaya, a manufacturer
of Lithium Ion SuperPolymer batteries, announced that it has delivered a 1.5MWh
capacity Lithium Ion SuperPolymer Battery Energy Storage System
(“BESS”) to Arizona Public Service Company (APS), Arizona’s largest
electric utility, for a pilot program to study ways to optimize the integration
of renewable energy sources to the grid.
APS plans to run the pilot for two years at a substation
near the site and the system will be used at a nearby residential-scale solar
power plant by near future.
“Working with major utilities represents a
tremendous opportunity for us in the rapidly growing grid energy storage
market, and validates the importance of our advanced battery technology and
unique toxic chemical-free manufacturing process,” said Dr. Raj Das
Gupta, general manager, energy storage systems, Electrovaya.
Electrovaya boasts the system is the world’s largest
Lithium Ion battery in a single container. The company partnered with ABB, a
power and automation technology company, to provide the power conditioning and
conversion equipment for the battery energy storage system.
“ABB is excited to work with Electrovaya on this
important grid battery energy storage project. Electrovaya and ABB will be
working closely together on this and other opportunities, as we meet the
growing demand for clean energy via safe and reliable technology,” said
Pat Hayes, ABB account manager of Energy Storage Systems.
Energy Storage with lithium batteries stores energy from
intermittent generating sources such as wind and solar and makes it available
to electricity users at Peak Power or on demand.
Energy storage will help APS integrate more renewable
energy onto its system. Energy storage enables APS to store solar energy during
the day and dispatch it in the evening.
Recently Electrovaya reported the fiscal 2011 revenue increased by 104 percent
to $10.3 million, over the previous fiscal year. Fourth quarter fiscal 2011
revenue totaled $2.6 million, a 50 percent increase over the
fourth quarter of the previous fiscal year.
