Stonybrook University is a 1,040-acre main campus located on the north shore of Long Island. The Stony Brook University campus electrical distribution system is served by three redundant feeds. Power supply is fed from either one of the two 69KV, three-phase electric utility feeders supplied by LIPA/PSEG or from the 45 megawatt (MW) co-generation plant owned and operated by Calpine. The current campus structure allows for complete system redundancy where no buildings or areas are without power during an outage, allowing the campus to stay online in case of widespread power outages.
