Green Mountain Power’s Stafford Hill microgrid, a 4MW/3.4 MWh battery energy system integrated with solar generation in western Vermont, exemplifies the multiple uses and significant revenue potential of advanced energy storage combined with solar PV in a microgrid configuration, behind a utility meter. This project was commissioned in 2015. It provides power resiliency for critical infrastructure while earning revenues for the operator. Savings from peak shaving have been demonstrated.
