The COVID-19 impact on global economies and industries will still be felt for a long time even though life has started to return to some sense of normalcy. However, the increasing competitiveness and critical role of battery energy storage assets in supporting the decarbonization and resilience of the electricity system means that opportunities for energy storage continue to develop despite the turmoil caused by the pandemic.

Utility regulators and operators are rebuilding the bulk power system to make it more resilient and better able to accommodate higher penetration levels of variable renewable generation. One of the prime movers in this energy transformation is the rapid advancement of battery storage technologies. There are different application characteristics, which underscore the need for different batteries and battery technologies. Some chemistries or technologies are better suited for short-duration power applications, whereas others are better suited for long duration energy applications so no one battery is the ideal tool for all applications.

This advanced course will provide an in-depth overview of the various types of long duration batteries and address things you need to consider such as battery characteristics, projected life, performance, and costs.  This course also covers battery storage applications, utility scale implementations, safety, design considerations, use cases, system resiliency and the future of storage.
