The IRS just published its annual notice that provides the inflation adjustment factors and reference prices used in determining the amount of the section 45 production tax credit (PTC) for the production of renewable energy and refined coal.
The credit for the production of renewable energy from wind, closed-loop biomass and geothermal facilities remains at 2.4 cents per kilowatt hour for 2018. The credit for the production of renewable energy from open-loop biomass, small irrigation power, landfill gas, trash, qualified hydropower, and marine and hydrokinetic facilities remains at 1.2 cents per kilowatt hour. The credit for the production of refined coal is $7.03 per ton for 2018 (up from $6.909 in 2017). No phase-outs apply to the credits for these energy resources in 2018.
