Duke Energy (NYSE: DUK), Samsung SDI and Younicos will work together to update Duke Energy's 36-MW energy storage and power management system at its Notrees Windpower Project in west Texas.
The system has been operating since 2012 with lead acid batteries. By 2016, these batteries will be replaced with lithium-ion technology.
"The Notrees Energy Storage Project has proven to be a valuable asset, achieving the objectives of our partnership with ERCOT (Energy Reliability Council of Texas) and the Department of Energy," said Greg Wolf, president of Duke Energy, Commercial Portfolio. "Because battery technology is rapidly evolving, we have an opportunity to upgrade the facility to better match the function that has become most valuable in the Texas market -- fast response frequency regulation."
Currently, Duke Energy owns nearly 15 percent of the grid-connected, battery-based energy storage capacity in the U.S., according to independent research firm IHS Energy.
Samsung SDI will serve as the primary engineering, procurement and construction manager; and will provide its lithium-ion batteries and Battery Management System (BMS).
Younicos will supply its energy storage management system (ESMS), including its system design, engineering, software integration and testing, and post-implementation engineering services.
