EnSync Energy’s project engineers consulted with JWCC to size the non-exporting system to meet the center’s current operational needs while allowing room for expansion. The resulting solar plus storage project encompasses a 148-kW photovoltaic installation and EnSync Energy’s DER SuperModule™—244 kWh of energy storage supported by EnSync Energy’s Matrix™ Energy Management System and DER Flex™ technologies. The alternating current, PV-only system directly serves the buildings’ loads, and a direct current system connected to the SuperModule stores energy for off-peak solar hours and for demand charge mitigation.
JWCC provides over 43,000 square feet of office space across six individual buildings to 16 resident agencies, including The American Cancer Society – Hawaii Pacific, The American Red Cross and TheMaui Chamber of Commerce. The center also provides program space and support resources to over 250 community groups that together serve 30,000 Maui residents. Beyond cost reductions from the lower PPA rate, JWCC will benefit from demand charge mitigation services, which will decrease the center’s utility bills by relying on energy storage to manage high demand charges.
