Imergy, Geli to Provide Energy Storage for College Microgrid

February 13, 2015 By Linda Hardesty

Imergy energy manageLas Positas College in Livermore, Calif., Imergy Power Systems, and Growing Energy Labs (Geli) will participate in a microgrid project funded by a $1.5 million grant from the California Energy Commission to enable the Chabot-Las Positas Community College District to integrate renewable energy sources into its operations and curb peak power.

The district will install Imergy Power Systems’ EPS30 series institutional scale vanadium redox flow batteries with a total capacity of 250 kW, which stores 1 MWh, as part of the microgrid, which will be managed by Geli’s Energy Operating System and Energy Management applications.

The energy storage system, to be installed onsite at Las Positas College in Livermore, will enhance an existing 2.35 MW solar array that generates 55 percent of the energy needed at the campus, 3,200 ton-hours of ice thermal storage, and ten Level II EV charging stations to form a smart microgrid, capturing about $75,000 in annual energy savings for the district.

This project will allow the partners to develop a microgrid blueprint model that can be used by other colleges.
