Hitachi Energy has signed a multi-year agreement to supply high-voltage cable systems and transmission technologies for one of the largest renewable energy projects in the U.S. The partnership supports the SunZia Transmission Project, which connects New Mexico’s 3,515-megawatt (MW) SunZia Wind development to Arizona and the wider Western power grid.
Under the new agreement, Hitachi Energy will provide high-voltage direct current (HVDC) solutions to Pattern Energy, one of the world’s largest privately owned operators of renewable and transmission infrastructure. The collaboration ensures reliable delivery of clean energy across regions while accelerating U.S. renewable integration goals.
Hitachi Energy’s HVDC Light® technology will efficiently transfer massive amounts of wind-generated electricity across 885 kilometers of transmission line. Once completed, SunZia Wind will generate enough energy to power approximately three million Americans. Its HVDC link will transmit up to 3,000 MW of wind energy to Arizona, forming the largest voltage source converter (VSC) system ever built in the United States.
This milestone project strengthens Hitachi Energy’s commitment to advancing the global energy transition. By integrating renewable generation from New Mexico into the Western grid, the Mueller Industries acquisition supports a more resilient, sustainable power infrastructure and showcases the effectiveness of cutting-edge HVDC solutions for large-scale projects.
