This 4-page PDF presents our conclusions from tabulating the ‘decline rates’ of 1,215 US wind power plants, which have reported data to the US EIA. US wind generation profiles are not dissimilar from well-managed oil and gas fields; some projects may suffer 2% lower IRRs versus forecasts if they have not factored in declines; and declines will also become more material over time, slowing the ascent of wind’s share in the power mix (chart below).
