SunZia Construction
Pattern Energy is building SunZia Wind and Transmission. The Project consists of over 3,500 MW of new wind generation located in Torrance, Lincoln, and San Miguel Counties, New Mexico and a 550-mile ±525 kV high-voltage direct current (HVDC) transmission line between central New Mexico and south-central Arizona.
Construction is underway in Arizona and New Mexico on the wind project and transmission line.
SunZia Wind | Construction Updates
Construction on SunZia Wind began in September 2023 and is expected to be completed by mid-2026. Construction on the Project is divided into two sections: SunZia Wind North and SunZia Wind South, and each section is divided into zones. See below for a detailed map of the Project.
Latest Update: Winter 2024/2025
Current Activities
- SunZia Wind South:
This fall the first wind turbines were erected in Wind South Zone 1 with over 39 turbines standing fully erected at this time. - SunZia Wind North:
Access road construction and foundation pouring continue in Wind North Zones 1 and 2. Recently, Wind North Zone 3 achieved the milestone of 100% completion on access roads and foundation pours.
Scheduled Traffic Impacts
- Wind South turbine tower and component deliveries continue along NM Highways 42, 54, and 247. Most of the turbine deliveries along Highways 42 will conclude by the end of this year. Turbine deliveries along HWY 247 will continue throughout next year, and we anticipate turbine deliveries wrapping up completely in November 2025.
Completed Activities
- SunZia Wind South:
The first wind turbines have been erected, and nearly half of the foundations have been completed. - SunZia Wind North:
Access roads have been 52 percent completed, and we’re making good progress on the foundations with 43 percent complete.
