From the Document: "The renewable electricity production tax credit (PTC), a per-kilowatt-hour (kWh) tax credit for electricity produced using qualified renewable energy resources, expires on January 1, 2021. Thus, under current law, the credit is not available for projects that begin construction after December 31, 2020. Whether the PTC should be extended, be modified, or be allowed to expire is an issue that may be considered in the 116th Congress. [...] This report provides a brief overview of the renewable electricity PTC. The first section of the report describes the credit. The second section provides a legislative history. The third section presents data on PTC claims and discusses the credit's revenue consequences. The fourth section briefly considers some of the economic and policy considerations related to the credit. The report concludes by briefly noting policy options related to the PTC."
