Duke Energy to Use Lithium-Ion Batteries at Notrees Project – Analyst Blog
Diversified energy company Duke Energy Corporation DUK will upgrade its 36-megawatt (MW) energy storage and power management system at Notrees Windpower Project in west Texas. This unit is presently storing energy in lead acid batteries. The company has plans to replace these batteries with lithium-ion batteries over the course of 2016. Samsung SDI and Younicos will help Duke Energy in the upgrade process.
The Notrees Energy Storage Project is helping Duke Energy to meet its partnership obligation with ERCOT (Energy Reliability Council of Texas) and the Department of Energy. Thanks to the energy storage system, Duke Energy could maintain the frequency in ERCOT grid, by either dispatching stored energy to increase frequency or by absorbing energy to decrease frequency as per ERCOT’s requirement.
Samsung SDI will act as the primary engineering, procurement and construction manager and will provide its high-performing lithium-ion batteries and associated Battery Management System (BMS). Younicos will provide its energy storage management system, which will work in concert with the Samsung SDI software and batteries. The new lithium-ion batteries will increase the efficiency of Duke’s Energy storage system and lower its cost of operation.
