Our newest market report details the latest U.S. wind industry, utility-scale solar, and energy storage activity and trends.

The report includes:

  • new wind capacity installations in 2020
  • wind projects under construction and in advanced development
  • new power purchase agreements
  • turbine OEM market share
  • project acquisition activity
  • offshore wind energy activity

For the first time, the report also includes data on utility-scale solar and energy storage.

The public version of the report provides a summary of key takeaways and graphics from the full report, which is available for ACP members.  ACP’s future quarterly reports will include the association’s own data on utility-scale solar and energy storage, along with wind.

Fourth quarter highlights include
