127 Energy built a 5 MW/11.6 MWh battery storage system, combined with a 1.2 MW solar PV system, to provide a resilient clean energy microgrid for a Roche Company facility in Oregon. Throughout the year, this system provides environmentally intelligent energy that offsets facility emissions. Uniquely, this system also serves as an uninterruptible power source (UPS) for the entire campus in the event of a power outage.
Power outages can cost this Roche facility well over $2 million dollars if the outage extends beyond 75 milliseconds. Our scope on this project was to develop an incredibly resilient battery system that could pick up the facility load in less than 40 milliseconds and provide a seamless transfer. Since the system began operating, the customer has already saved millions by avoiding power disruptions to facility equipment during short sags in utility voltage. If needed during a longer outage, the solar and battery system can keep the large facility powered for 4-8 eight hours depending on the processes operating in the facility.
