In a study conducted by the Department of Energy in March 2016, it was apparent Maine's CHP capacity has room to grow. Maine has 494 MW of CHP technical potential capacity identified at 1,385 sites.[2]

Policy & Incentives

Maine has a number of programs and incentives designed to promote and support new and existing CHP projects. The State's "Large Customer Program" offers a non-proscriptive, rate payer funded program for CHP among other DER. In addition, there is CHP Technical Assistance Funding that pays for up to 50% of the project study needed to qualify for the Large Customer Program. The requirement attached is that the customer, and not the vendor, must share in the copay. Lastly, Maine offers incentives of up to 50% of installed costs with some restrictions. These incentives are capped at $1 Million per year per project, and is also based on annual reductions. For more information, see
