The Notrees Wind Storage Demonstration Project installed an advanced battery energy storage system (BESS) with a capacity of 36 MW/24 MWh to optimally dispatch energy production from the wind farm. Such optimization could help energy storage operators capture energy arbitrage, improve grid stability, and demonstrate renewable firming value. Additional carbon dioxide (CO2) reduction benefits could also be realized, as energy storage will eliminate the need for fossil-fuel-based secondary generation that currently supports many wind farm operations.
