Public scoping meeting

Battery Energy Storage Systems Scoping Document available for review

Sept. 23, 2026, 1 p.m. PT, Webinar

We are seeking public input to help us determine what to study in the Battery Energy Storage Systems Programmatic Environmental Impact Statement. The virtual meeting includes a presentation and a public comment session.

Live Spanish interpretation will be provided in this Zoom meeting.

Background

We are starting work on a statewide study of battery energy storage systems. The study will look at potential negative environmental impacts and ways to avoid, reduce and mitigate impacts. 

Battery energy storage systems, or ‘BESS’, use large, rechargeable batteries to store energy. They release power when people need more electricity or when power generation decreases. They can also provide backup power during outages and help strengthen the state’s electrical grid.  

The scoping document explains the study process and gives a general overview of battery energy storage.
