Danbury-based FuelCell Energy has sold the project company that owns the 1.4 megawatt fuel cell power plant located at Trinity College in Connecticut, to AEP OnSite Partners.  FuelCell Energy will operate and maintain the power plant under a 15-year service agreement with AEP OnSite Partners.  Trinity College officials thanked FuelCell for bringing the project to fruition, which they say makes both environmental and economic sense for Trinity.  Adjacent to the school’s athletic center, the steam produced by the plant will supply the centralized steam system, minimizing the use of boilers for the heating process.
