SunZia Wind Project Begins Operations in New Mexico
The 550-mile transmission network delivers wind power from central New Mexico to western states after a 17-year wait to break ground.

Should the government make it easier to approve large energy projects like transmission lines?
The SunZia Wind and Transmission project, with more than 900 turbines across central New Mexico, began operations this summer. The facility generates more electricity than the Hoover Dam, though lawsuits from tribal communities and environmental advocates remain pending.
Why it matters
National electricity demand is projected to rise, making large-scale renewable generation and transmission a growing priority. For New Mexico, the project reflects a shift from the 2018 rejection of the initial transmission route to a build-out now serving western markets.
The project spans 900+ turbines and a 550-mile transmission line, with electricity consumption projected to rise 25 percent by 2030 and 78 percent by 2050. Pending lawsuits and the unmeasured 9 million metric tons of expected CO2 reductions remain open questions.
The players
White Sands Missile Range
A U.S. Army installation in southern New Mexico whose approvals were required for the transmission line's route and buried segments.
The details
Portions of the transmission line are buried in the White Sands Missile Range area, and construction required approvals from the Missile Range. The project was first proposed in 2006 and went roughly 17 years before breaking ground.
Timeline
2006: SunZia was originally proposed.
2018: New Mexico rejected the initial transmission route.
Summer 2026: The project commenced operations.
By next summer: The wind farm is expected to prevent about 9 million metric tons of carbon dioxide emissions.
End of the decade: Electricity consumption is expected to rise 25 percent.
Market Landscape
The 2018 rejection of the original transmission route marked a major setback for SunZia, which was first proposed in 2006. Its operational start now positions the project as a large-scale wind source serving California and Arizona.
Western utilities receiving SunZia power may see changes to regional electricity supply as the project delivers energy from New Mexico. Households in the region could be affected by shifts in generation sources and long-term electricity costs as demand grows.
The takeaway
Large renewable projects can take well over a decade to reach construction, so permitting and land-use decisions shape energy supply long after they are first proposed. Readers tracking regional power costs should watch how the pending lawsuits are resolved.
