- The Renewable Electricity Production Tax Credit (PTC) offers wind, solar, geothermal, and closed-loop biomass systems a 1.8 cent credit per kilowatt hour generated. The credit is 0.9 cents per kilowatt hour for open-loop biomass, landfill gas, waste incineration, and small hydro (less than five megawatts) (EPA, 2015).
It provides incentive payments for electricity generated and sold by new qualifying renewable energy facilities. Qualifying systems must generate electricity using
1. solar,
2. wind,
3. geothermal (with certain restrictions)
4. biomass (excluding municipal solid waste)
5. landfill gas
6. livestock methane
7. ocean resources (including tidal, wave, current and thermal).
