Biomass, or renewable energy from waste such as forest debris, agricultural waste and scrap lumber, is quickly gaining popularity as an addition to many renewable portfolio standards (RPS) across the United States. Ameresco helps customers and communities harness the potential of biomass energy by building power and cogeneration facilities that cleanly burn renewable waste to fuel specialized engines that generate power and heat.

We can create large, utility-scale biomass-to-energy plants, as well as smaller on-site biomass cogeneration and distributed generation plants that can fulfill a significant portion of a facility’s energy needs, reducing energy costs, water consumption and air emissions. Ameresco has different ways of assisting with financing this technology through power purchase agreements (PPA), own and operate solutions or an energy savings performance contract (ESPC).
