In the first half of 2026, the US power sector saw significant developments, including the launch of 368 utility-scale power plants, primarily solar, according to data from the US Energy Information Administration.

The SunZia projects have been in development for approximately ten years, coinciding with a decrease in onshore wind power development in the US due to various regulatory and public opinion challenges.
