By Dr. Jud Virden, Associate Laboratory Director, Energy & Environment Directorate, Pacific Northwest National Laboratory, USA.
Over the last several years, large battery energy storage systems (BESS) have been deployed for a variety of grid applications. For these applications, BESS are expected to follow signals corresponding to power intensive and energy intensive applications for long periods of time without degradation of performance. This presentation will discuss the performance of five BESS that are operational for a variety of grid applications. The batteries systems range in size from 5MW-1.14MWh to 2MW-8.8MWh. The BESS represent both lithium ion and vanadium redox flow systems. We will discuss the performance of the battery systems for arbitrage, regulation, load following and other grid applications. This presentation will also discuss the stacking of applications, that return the greatest value to the stakeholders based on application-specific BESS performance and degradation.
