Ameresco to build renewable-powered microgrid for US Marine Corps
Energy Storage, January 13, 2017
Ameresco will build a renewable-powered microgrid at a Marine Corp facility in Parris Island, South Carolina.
The project at the Marine Corps Recruit Depot (MCRD) includes 6.7MW of PV generation, a 3.5MW combined heat and power facility and a 8MWh battery storage system.
A US$91.1 million Energy Savings Performance Contract (ESPC) has been put in place to fund Ameresco’s engineering, construction and operation works. The ESPC uses the electricity bill savings delivered by the system to pay down its cost. This is essentially cost-neutral for the client.
According to Ameresco the microgrid control system will monitor and coordinate the dispatch of the energy assets. Emergency diesel generators will also be used in response to site electrical loads. The microgrid control system will monitor the health of the utility connection and, when a utility disturbance is sensed, safely disconnect the site while matching load to available onsite generation through fast load shedding.
It will also maximise savings and lengthen the system’s lifespan by optimising the operations and maintenance of the microgrid across the 121 buildings on the site.
Construction is expected to begin in Spring 2017 with completion timed for Summer 2019.
