Microgrids: Energy independence (and money saved) for companies

ANDOVER, Mass. -- At the end of a heavily wooded, sparse industrial park here sits the North American headquarters and R&D center for Schneider Electric, which earlier this month unveiled its own campus power microgrid.

The microgrid for the global energy management conglomerate is expected to produce 520,000 kilowatt-hours (kWh) of electricity per year, or 10% of Schneider Electric's power needs. It's also expected to reduce its energy costs by 20%.

Perhaps more importantly, the microgrid incorporates a natural gas generator as an anchor resource, allowing solar panels to operate during grid outages to maintain critical operations. In the event of a power outage, a lithium-ion battery storage system would provide up to 100KW of power for an hour.
