Enabled by HVDC Light®, the SunZia Transmission Project connects a wind farm in New Mexico to the power grid in Arizona, increasing renewable energy to western states.

ZURICH, SWITZERLAND, May 4, 2023 (GLOBE NEWSWIRE) — Zurich, Switzerland, May 4, 2023 – Hitachi Energy, a global technology leader driving a sustainable energy future for all, has been selected by Pattern Energy as the supplier of high voltage direct current (HVDC) and other advanced technologies for the SunZia transmission project. Chosen. This will connect his 3,500 megawatt (MW) SunZia wind farm project in New Mexico to the grids in Arizona and Southern California, making him one of the world’s largest power grids supplying renewable energy. becomes.

Hitachi Energy’s HVDC Light○○R; The technology efficiently transfers and integrates vast amounts of wind power into the regional power grid over more than 885 kilometers (550 miles). This will significantly increase the sustainable energy available to homes and businesses across the region.

When completed, SunZia Wind will have a total power capacity of 3,500 MW, enough clean, renewable electricity to power nearly 3 million Americans.1 The HVDC link will efficiently transmit up to 3,000 MW of this power west to Arizona. HVDC light○○R; The system is the largest voltage source converter (VSC) installation in the United States, one of the largest installations in the world, and one of the longest HVDC connections in the country.

“We are committed to advancing a sustainable energy future for everyone in the U.S. Southwest so that Pattern Energy can integrate emissions-free electricity into the regional grids that serve Arizona and Southern California. We are proud to do so.” said Niklas Persson, Managing Director of Hitachi Energy’s Grid Integration business. “By combining his market-leading HVDC technology and execution expertise, we will help the United States meet its carbon-neutral goals by efficiently and reliably maximizing renewable energy resources. We will be the perfect partner to help you.”

“Our collaboration with Hitachi Energy is an important milestone for the SunZia Transmission Project, allowing us to harness and deliver this enormous energy potential to regions with high demand for renewable energy,” said CEO of Pattern Energy. Hunter Armistead said: “The use of HVDC technology will increase the reliability and resilience of the power grid, providing clean energy in the United States and playing an important role in deploying sustainable energy systems. fulfill”

The SunZia Transmission project is a 3,000 MW HVDC link between Corona, New Mexico and Pinal County, Arizona. Hitachi Energy has already begun design and engineering work on two of his HVDC Lights.○○R; Conversion stations, one at each end of the link. Transmitting stations convert power from AC to DC for transmission over overhead lines and back to AC for integration into the receiving grid.

Hitachi Energy has partnered with Quanta Services, Inc. (Quanta) to provide a turnkey project solution for the SunZia Project, including managing HVDC construction and building installation at the associated project site. Quanta is an industry leader in providing specialized infrastructure solutions for the utilities, renewable energy, telecommunications, pipeline and energy industries. The collaboration with Quanta aims to leverage the core competencies of both companies to deliver best-in-class solutions for your projects. The HVDC conversion station is expected to be operational by the end of 2025 to support final testing and commissioning of his SunZia wind farm in 2026.

Expert consultants from Hitachi Energy performed system studies and comprehensive interconnection and system impact analyses, to find the best solution considering the impact of the new facility on the existing grid.

Hitachi Energy will also supply an “alternating current (AC) chopper”. A technology that assists in the restoration of power when the flow of power in the Arizona DC line or AC grid is temporarily interrupted by weather or other unforeseen circumstances.

Hitachi Energy has delivered over half of North America’s HVDC projects. These include the Pacific Intertie Transmission System, which will transmit power from the Pacific Northwest to Los Angeles, the Quebec New England Link, the world’s first large-scale multi-terminal HVDC transmission system, and the connecting Maritime Link. Helps integrate renewable energy sources and improves grid stability. The company also recently announced new his HVDC projects such as: Champlain Hudson Power Express, chateau gay Modernization of converter stations by Hydro Quebec, and Intermountain Power Project.2
