BESS (battery energy storage system)
A battery energy storage system is a set of batteries, inverters, controls and safety systems that stores electricity and releases it on demand. At a data center it can cover short gaps before generators start, shave peaks, support a microgrid or help a site meet a utility’s flexibility expectations. Fire code spacing, setbacks and local permitting for battery installations shape where a BESS can go on the site.
