SunZia Wind, the largest wind farm in the US, achieves commercial operation with 3.65 GW and 550-mile HVDC line

Pattern Energy/SunZia Wind and Transmission

Pattern Energy's SunZia Wind and Transmission project in southern New Mexico reached full commercial operation, with 916 turbines generating 3.65 GW. The accompanying 550-mile HVDC transmission line delivers power to Arizona and California utilities (Arizona Public Service and Southern California Edison). SunZia is now the largest wind farm in the United States.

• 3.65 GW makes SunZia the largest wind farm in the US; exceeds next two largest (Alta Wind ~1.1 GW, Great Prairie ~1.0 GW) by threefold
• 916 turbines (674 GE Vernova 3.6 MW + 242 Vestas 4.5 MW) expected to generate 12.5–13 TWh annually at ~40% capacity factor
• ±525 kV HVDC (largest VSC-based link in US) covers 550 miles with ~3% loss; transmits 3 GW, routing ~2/3 of power to California
• PPAs with Arizona Public Service and Southern California Edison provide stable revenue from 2–3 GW capacity
