Largest solar farm in each state, territory, and province

As the solar industry booms, it’s challenging to identify the largest solar farm in each U.S. state, Canadian province, and their territories. This is due to the near constant announcements of upcoming new facilities, as well as the headwinds that they can encounter during financing, site approval, and the regulatory approval process. As a result, the list below tries to traverse the myriad of solar projects to identify those that have been completed, have been approved, or are actually under construction to make the list as up-to-date as possible.

The most interesting factoid derived from this list is that the largest solar farm in the two nations is under development in Indiana (not a place one would normally expect) and will provide 1.3 gigawatts of power when fully completed in 2024.

Any additions, corrections, or suggestions are most welcome and the list will be updated from time to time.
