GE, Arista Power sign energy storage technology agreement

Erie, Pa., April 23, 2012 ­— GE's Energy Storage business, a unit of GE Transportation, recently signed a business cooperation agreement with Arista Power, Inc. to jointly promote and market Arista's new Power on Demand System that will incorporate GE's Durathon Batteries.

Arista Power, a manufacturer, designer and integrator of renewable energy generation, management and distribution systems, has selected GE's Durathon Battery system for use in its Power on Demand Systems.

GE's Durathon Battery is the product of a $100 million investment in battery energy storage technology. Durathon is a nickel salt battery that is marketed for telecommunications, utilities and uninterruptable power supply applications.

GE's Durathon is 50 percent smaller and 25 percent lighter than traditional batteries, enabling more energy to be stored in a smaller space. In addition, Durathon Batteries can last up to 20 years, operate effectively in extreme temperatures, are recyclable, and require no cooling and only minimal maintenance.

GE's Durathon Battery cells are recyclable, making the battery a sustainable technology. GE's new battery plant is located in Schenectady, N.Y.

Arista's Power on Demand system reduces electricity demand charges, which are based on a customer's peak power demand and can account for up to 30 percent to 70 percent of a commercial electric bill. The patent-pending system uses energy generated by wind turbines, solar PV, the electric grid, and other power sources in conjunction with a custom-designed battery storage system and proprietary real-time demand monitoring technology.

The monitoring system is designed to smooth power demand on the grid by maintaining grid demand within optimal parameters and releasing stored power only during peak demand periods, thereby reducing peak demand charges, prolonging battery life and lowering commercial electricity costs.
