Energy Storage Technologies being tested by California & Ohio Smart-Grid programs
A system of large-format batteries that can store enough energy locally to provide electricity for thousands of customers is at the heart of ambitious energy storage technology tests planned for several U.S. states. California and Ohio are among the states participating in the innovative Smart Grid programs.
Ohio’s tests feature the unique Community Energy Storage (CES) system designed by S&C Electric Company for American Electric Power (AEP). The system features a series of large-format lithium ion batteries supplied by International Battery. A $75 million Department of Energy (DOE) grant is being used to partially fund the Ohio smart-grid project. Approximately 110,000 customers in a roughly 25 square-mile area will benefit from the test.
Pacific Gas and Electric in California is testing giant sodium-sulfur batteries as a means of energy storage on the grid. A $2 million grant from the California Energy Commission (CEC) will go towards the construction of a $15 million, 4 megawatt (MW) system that will provide enough energy storage for a whopping 24 megawatts per hour.
‘Super Batteries’ like the lithium-ion batteries and sodium-sulfur batteries store energy locally for those times when the demand exceeds the power company’s output or to address local power outages.
