NEM 3.0 motivates home battery energy storage with growing fire risk

Image
The CPUC NEM 3.0 will intentionally motivate home owners to use home Battery Energy Storage Systems for time shifting instead of using the grid, by paying only 8 cents/kWh to upload energy to the grid, versus  30 cents for downloading it. They are thus setting up homeowners to face a new fire threat, due to the significant hazard of Lithium ion battery storage systems. According to recent lessons learned on BESS fire prevention and mitigation published by the Electrical Power Research Institute (EPRI) in June 2021, over 30 large-scale BESS globally experienced failures that resulted in destructive fires over the past four years (Long, 2021). These events are also tracked in the publicly accessible BESS Failure Event Database (EPRI, 2022). Most events had in common that the lithium ion batteries installed in the BESS where somehow driven to vent battery gas and transition to thermal runaway, which is a process that releases large amounts of energy. Thermal runaway is strong...
