How does battery storage work?
Battery storage works by absorbing electricity when it’s abundant on the power grid and sending excess power back to the grid when it’s most needed, such as during the evening after the sun sets and solar energy fades away. Boulevard Microgrid and Battery Energy Storage System Project Helps advance our state's and region’s renewable energy goals.
Why is battery storage important in a microgrid?
Battery storage is an important part of every microgrid. Battery storage works by absorbing electricity when it’s abundant on the power grid and sending excess power back to the grid when it’s most needed, such as during the evening after the sun sets and solar energy fades away. Boulevard Microgrid and Battery Energy Storage System Project
Where are SDG&E battery systems installed?
Typically, these battery systems and microgrids are installed on SDG&E-owned property; they are adjacent to our existing substation facilities or in critical locations where grid reliability and resiliency is needed most.
