S&C Electric Company, a global leader in smart grid solutions and renewable energy integration, announces today a turnkey energy storage project that will help Southern California Edison (SCE) reduce its greenhouse gas emissions. SCE awarded S&C a contract to furnish a turnkey 1-MW S&C Smart Grid SMS™ Storage Management System on Catalina Island, off the coast of California. The Smart Grid SMS is a fast-responding automatic controller that uses built-in intelligence to control charging and discharging of sodium-sulfur batteries.
The energy storage system will help reduce greenhouse gas emissions from the island’s diesel generators. With no tie to the mainland, the diesel generators are not best equipped to handle power demand, which fluctuates throughout the day. By deploying stored energy during times of peak power demand, the Smart Grid SMS permits Catalina Island generators to run at a specific percentage of capacity for optimal performance and decreased carbon emissions.
“Working with an islanded grid poses unique challenges for reliable power delivery,” says Thomas Barker, Senior Engineer, Southern California Edison. “Installing a comprehensive storage system helps us run more efficiently and reduce our emissions – all while effectively managing load changes to ensure consistent service for our 3,000 island residents plus the many visitors to the island.”
S&C is the most experienced provider of energy storage systems – a new and highly complex technology – in the U.S. Since 2006, S&C has successfully furnished, installed and commissioned 12 MW of sodium-sulfur battery storage throughout the country, with another 12 MW planned for 2011. Among the completed projects are three of the world’s first islanding applications.
“Energy storage enhances utilization of renewable energy resources, and it reduces the need for fossil-fuel-fired generation to serve peak demand and maintain a stable grid,” says Jim Sember, S&C Vice President—Power Quality Products. “S&C continues to innovate new solutions that are helping utilities realize the full potential of energy storage in building a greener grid.”
