There is a “high probability” the US will add 27.1GW of new wind power generating capacity and 16.3GW of utility-scale solar by June 2022, according to data compiled for the Federal Energy Regulatory Commission (FERC).

In its May 2019 Energy Infrastructure Report, FERC notes that developers have proposed 99GW of new wind capacity and 85.4GW of solar nationwide.

The implication is that much of this capacity sitting in regional or state grid queues seeking interconnection will not get built due to financing and off-take problems, regulatory delays, transmission congestion and other issues.
