Case Studies

Portsmouth Naval Shipyard

Normally, the Portsmouth Naval Shipyard operates in a cogeneration mode with Central Maine Power. The installation of gas turbines and backup diesel generators has made the shipyard self-sufficient (if necessary) for the critical requirements of the facility should there be a loss of service from Central Maine Power.

Ameresco and Great Lakes have implemented over $100 million in facility upgrades. These projects were spread out over multiple phases that included 15 to 20 buildings per phase. Ameresco developed a Master Plan for Great Lakes that focused on leveraging projects based on savings potential to maximize facility upgrades.
