Wind is positioned to be the cheapest source of US electric generation even after the federal production tax credit (PTC) steps down in 2023 and it will then experience 15% annual growth through 2030, according to market leader NextEra Energy Resources.

The company estimates $30-35/MWh levelised cost of energy (LCOE) for wind in 2020 (pre-tax over project life) including about $20/MWh PTC value and $10-15/MWh PPA value.
