Arizona to be part of expansive Southwest renewable energy project approved by US.
The US Department of the Interior has approved the SunZia Southwest Transmission Project, a 520-mile transmission line that will transport renewable energy from New Mexico to Arizona and California. The project will provide 4,500 MW of primarily wind-generated electricity and create union jobs. It is the largest clean energy infrastructure project in the US to date and is part of the Biden Administration's goal of achieving a 100% clean electricity grid by 2035. Construction will begin this summer, and commercial operations are targeted for 2026.
