Battery manufacturer partnership results in ‘load’ reduction and
energy-management solutions for major SCE customer
SANTA FE SPRINGS, Calif., June 12, 2007— Southern California Edison (SCE) today presented an energy rebate check for $576,627 to Trojan Battery Co. to assist with its efforts to achieve long-term energy savings at its Santa Fe Springs, Calif. manufacturing plant.
To date it is the single largest project completed under SCE’s Technical Assistance and Technology Incentives Program, which provides financial incentives for the installation of technologies that reduce electricity use during high-demand periods. Along with other improvements at the plant, Trojan now can completely automate its demand-response options and shed 3.4 megawatts (MW) of its 4 MW (85 percent) ‘load’ within minutes with a minimal and manageable short-term impact to production.
SCE’s Business Customer Division, Tariff Programs and Services, and Electric Transportation Department worked closely with Chad Bentley, manager of manufacturing technology for Trojan Battery, as part of a complete upgrade of its battery formation charging process.
As the leading supplier of batteries to the golf-car industry, Trojan contributes to California’s ever-growing use of clean, efficient, off-road electro-drive technologies.
Lynda Ziegler, SCE’s senior vice president of customer service, said that the Trojan project demonstrates the value of energy efficiency, and demand response for all businesses so they can operate more cost-effectively, while minimizing demand on SCE’s electric system.
“This showcases SCE’s commitment to providing customers with the tools they need to effectively participate in demand-response programs that benefit them directly and support California’s efforts to ensure reliable electricity supplies during peak-use periods,” Ziegler said.
Bentley said that manufacturers typically charge batteries with simple, inefficient, two- or three-step processes. The challenges with the old equipment, made it impossible for Trojan to effectively participate in energy saving, demand response programs.
“Trojan Battery and SCE worked to develop, and implemented computerized demand-response integration software that allows the company to reduce or interrupt the battery charging process at certain points, thereby allowing Trojan to reduce its energy demand within minutes by a click of a mouse,” Bentley said.
- SCE is the nation’s leader in energy-efficiency savings. During the past five years, SCE’s energy-efficiency programs have saved more than 4 billion kilowatt-hours (kWh) – enough energy to power 500,000 homes for an entire year - and reduce greenhouse gas emissions by more than 2 million tons – the equivalent of removing 250,000 cars from the road.
- During the next two years, SCE will help customers save an additional 2 billion kWh, reducing greenhouse gas emissions by another 1 million tons.
- More than 2,200 SCE business customers and 227,000 residential and small commercial customers participate in the largest set of voluntary demand-response* programs in California, and one of the largest in the nation, reducing power demand when conditions require activation of these programs.
- SCE demand-response programs have about 1,600 MW** of enrolled capacity reductions with an expected reduction potential of almost 1,200 MW.
- SCE’s renowned Electric Vehicle Technical Center in Pomona, Calif., tests, evaluates, and demonstrates advanced vehicle-drive systems, battery types and charging infrastructure. This work supports SCE’s commitment to reducing California’s dependence on foreign oil, lowering greenhouse gas emissions and improving air quality.
*Demand-response programs provide utility customers with financial incentives in return for voluntarily reducing electricity usage during periods when power generation or delivery is restricted.
**One MW is enough power to serve about 650 average Southern California homes.
