Duke Energy, LG Chem and Greensmith teamed up to build a battery-based energy storage system in Ohio, designed to enhance reliability and increase stability on the electric power grid. The new 2-MW storage project will assist in regulating electric grid frequency for PJM, the transmission organization that powers much of the eastern U.S. The system will be built at Duke Energy's retired W.C. Beckjord coal-fired power plant in New Richmond, Ohio, and is expected to be operational by late 2015.
Perhaps the best way to think of energy storage is as an injection of much-needed intelligence for the grid. Energy storage will fine-tune the relationship between a bewilderingly complex asset base and a sprawling, diverse and demanding spectrum of customers in real time. Energy storage systems will act like energy grid computers and control systems, not just bulk repositories for electrons.
