Hitachi Energy, a driving force in promoting a sustainable energy future, has been chosen by Pattern Energy to provide its high voltage direct current (HVDC) system for the SunZia Transmission Project. This colossal project will connect the 3,500 megawatt (MW) SunZia Wind Project in New Mexico to the power grid of Arizona and Southern California, making it one of the largest renewable energy transmission networks in the world.
The Power Of HVDC Light Technology
Hitachi Energy’s HVDC Light® technology will be used to transfer and integrate large volumes of wind energy over more than 885 kilometers (550 miles) into the regional power grid. The result will be a significant increase in the availability of sustainable energy for homes and businesses throughout the region.
Huge Capacity And Sustainability Of The SunZia Project
When completed, the transmission project will have a total capacity of 3,500 MW, providing enough clean and renewable energy to power approximately three million Americans. The HVDC link will be able to transmit up to 3,000 MW of that energy to western Arizona, making the HVDC Light® system the largest voltage source converter (VSC) installation in the United States, one of the largest in the world, and one of the longest HVDC connections in the country.

Strategic Partnership With Pattern Energy
“Our market-leading HVDC technologies, combined with our execution expertise, make us the ideal partner to help the U.S. achieve its carbon-neutral goals while efficiently and reliably maximizing its renewable energy resources,” said Niklas Persson, Managing Director of Hitachi Energy’s Grid Integration business.
Benefits Of HVDC Technology
Pattern Energy also sees HVDC technology as a key piece in the development of a resilient power grid and delivering clean energy. “The use of HVDC technology will enhance the reliability and resilience of the power grid and play a vital role in providing clean energy and deploying a sustainable energy system in the U.S.,” said Hunter Armistead, CEO of Pattern Energy.
HVDC Converter Stations
The SunZia project will connect Corona, New Mexico, and Pinal County, Arizona, with a capacity of 3,000 MW. Hitachi Energy has already begun work on the project and the engineering of the two HVDC Light® converter stations, one at each end of the link.
Partnership With Quanta Services, Inc.
Hitachi Energy has partnered with Quanta Services, Inc. to provide a turnkey design solution for use in the SunZia project. Quanta is an industry leader providing specialized infrastructure solutions for the utility, renewable energy, communications, pipelines, and energy industries at large. The HVDC converter stations are planned.
