HVDC

Pattern Energy's 3.5 GW SunZia project in New Mexico—the largest clean energy infrastructure project in US history—started commissioning in April 2026, delivering power across a 550-mile HVDC line to California and Arizona.

Invenergy's 800-mile high-voltage direct current transmission line across four Midwestern states is pressing ahead with private financing after the Trump administration cancelled a $4.9 billion DOE loan guarantee and the Illinois Supreme Court upheld the project's state permit.
