On June 6, 2019, the US Internal Revenue Service (IRS) published a notice providing the inflation-adjustment factors and reference prices for the calculation of renewable electricity production tax credits (PTCs) under Internal Revenue Code (IRC) section 45 for 2019.  

The notice provides that the PTC for electricity produced from wind, as well as closed-loop biomass and geothermal energy, increased from 2.4 cents per kilowatt-hour (kWh) to 2.5 cents per kWh for 2019. The notice also includes the PTC amounts for electricity produced from other qualified energy resources. Specifically, the PTC for electricity produced from open-loop biomass, landfill gas, trash, qualified hydropower, and marine and hydrokinetic resources remains at 1.2 cents per kWh for 2019. The PTC for refined coal also increased from $7.03 per ton to $7.173 for 2019.

IRC section 45 provides the PTC for any taxable year in the amount of 1.5 cents per kWh of electricity produced by a taxpayer from a qualified facility using wind or closed-loop biomass and sold to an unrelated person during the 10-year period beginning on the date on which the facility is originally placed in service. The credit amount is reduced by one-half for electricity produced from a qualified facility using open-loop biomass, landfill gas, trash, qualified hydropower, and marine and hydrokinetic resources.

IRC section 45 also provides the PTC in the amount of $4.375 per ton of qualified refined coal produced by a taxpayer from a qualified facility and sold to an unrelated person during the 10-year period beginning on the date in which the facility is originally placed in service. 

IRC section 45 provides that the 1.5 cent amount and $4.375 amount are to be adjusted annually for inflation.
