Operational since 2013, the Plainfield Renewable Energy uses clean biomass to generate electricity enough to power 280,000 homes.
The acquisition marks Greenleaf’s sixth purchase in North America and increases its total renewable biomass capacity to more than 180MW.
Greenleaf Power president and CEO Hugh Smith said: "The Plainfield facility will increase Greenleaf’s scale and materially improve both the contracted revenues and the average PPA life of its portfolio.
"Plainfield solidifies Greenleaf Power’s presence throughout North America as the leading growth-oriented owner and operator of biomass facilities.
Connecticut Light and Power purchases the electricity generated at the facility, under a long-term offtake agreement.
The acquisition is part of Greenleaf Power’s plan to invest and develop projects which use biomass or other landfill material as feedstock to generate renewable energy.
"While most other renewable sources are intermittent, biomass provides reliable, predictable power under all conditions throughout the year," Smith added.
