Production Tax Credit Like other domestic energy sources, American wind power needs a stable, pro-growth tax policy. The Production Tax Credit (PTC) and the Investment Tax Credit (ITC) benefit American consumers by growing our economy, creating jobs, improving energy security, and supporting a new U.S. manufacturing sector. The credit is currently worth 2.3 cents for every kilowatt-hour of electricity generated for the power grid. These tax credits are intended to keep wind energy attractive for the investors who finance new wind farms as demand for low-carbon fuel sources continues to increase.
