Commercial Battery Storage
Commercial battery storage is a different product from residential systems, engineered for the three-phase power that runs most commercial operations and large facilities. SES has extensive experience designing and installing these systems, including Fortress Power and Tesla Megapack.
Reduce demand charges. Large energy users are billed demand charges based on peak consumption spikes, and a single spike can set your rate for the next six to twelve months no matter how efficiently you operate otherwise. A commercial battery actively manages your load profile, smoothing those spikes before they occur to eliminate or significantly reduce the charges that follow.
Keep critical operations running. Configured with islanding mode, your battery system can disconnect from the grid and run independently during an outage. Unlike a standard generator, it delivers seamless, uninterrupted power with no startup delay and no disruption to sensitive equipment. For manufacturers, data centers, healthcare facilities, and any operation where downtime is costly, islanding is as much a risk management tool as an energy asset.
