Windpower Monthly rating 4/5

Our rating is based on a combination of project pipeline, political and policy support, investor confidence and structural readiness of the country in terms of grid infrastructure, permitting process and local supply chain.

Forecast of installed and operating wind power capacity based on the latest statisitics and measured against the Windpower Intelligence database.

The United States is enjoying a relatively prolonged period of policy certainty following the 2016 decision to phase out its key incentive, the Production Tax Credit, over five years.

For almost two decades, the regular one- or two-year extensions, often as the incentive was about to expire, created a boom-and-bust cycle confusing developers and scaring off investors.

Some uncertainty remains post the 2021-end of the tax incentive, but the industry is confident it can operate at market prices by that time, with the rise of corporate power purchase deals becoming an important driver.

Much policy is directed at state level, with some states such as Texas and Iowa more friendly towards wind projects.

Transmission becoming a bigger issue, as the country starts needing to ship the vast amounts of generation in central and mid-west states to load centres of coastal cities. 

This offers an opportunity to offshore wind, which can be placed closer to major cities. Still in its infancy, the US could have over 12GW of offshore wind capacity in the first half of the next decade.
