• Demonstrates the Power of Quanta's Industry-Leading and Comprehensive High-Voltage Electric Transmission and Renewable Generation Solutions
• Projects are Additive to Quanta's Multi-Year Visibility and Growth Opportunity
• The SunZia Wind and SunZia Transmission Projects Are Designed to Produce and Transport Wind Power to Consumers in the Western United States and Represent the Largest Renewable Energy Project in United States History

Houston, TX /PRNewswire/ - Quanta Services, Inc. announced today that it has been selected by Pattern Energy Group LP (Pattern Energy) to provide comprehensive infrastructure solutions for the SunZia Transmission and SunZia Wind projects, which together represent the largest clean energy infrastructure project in United States history. Demonstrating the Power of One and its substantial scope and scale, Quanta will leverage the capabilities of multiple operating companies to execute these projects for Pattern Energy. Once completed, these projects will generate and transmit a significant amount of abundant wind energy from New Mexico to consumers in the western United States.

"Quanta's selection for these projects builds on a long-standing customer relationship of our industry-leading renewable generation solutions company, Blattner Company, and we appreciate the confidence that Pattern Energy has placed in Quanta to execute on these critical and historic renewable energy projects. We believe these awards validate the power of our combined high-voltage transmission and renewable generation solutions and demonstrate the value of our collaborative approach to providing comprehensive energy transition infrastructure solutions," said Duke Austin, Quanta's President and Chief Executive Officer. "North America's energy transition to a reduced-carbon economy is accelerating but remains in the early stages of a multi-decade process that will require significant investment in power grid and renewable infrastructure. We believe our self-perform capabilities and vertically integrated solutions allow us to provide greater cost, schedule and quality certainty to our clients, which also benefits consumers, and that the comprehensive approach we are taking on the SunZia projects can serve as a model for the renewable and utility industries going forward."

"The SunZia project is changing the landscape for renewable energy, and we need to ensure that we have the best team in place to help bring it to life. Partnering with Quanta Services, an industry leader in the electric power and renewable infrastructure industries, to help build the SunZia projects demonstrates our commitment to delivering a world-class clean energy project that New Mexico, Arizona and the entire country can be proud of," said Hunter Armistead, Chief Executive Officer of Pattern Energy. "Along with enough clean power for 3 million American consumers, SunZia is designed to bring a far-reaching economic boost to the region, including the expected creation of over 2,000 new jobs and an expected $20.5 billion in economic impact."

SunZia Transmission
The SunZia Transmission project is designed to transmit approximately 3,000 megawatts of electricity generated by the SunZia Wind project on an approximately 550-mile, primarily bi-directional, +/-525 kV high-voltage direct current (HVDC) transmission line from central New Mexico to south-central Arizona, facilitating the transportation of renewable energy to the western United States. Quanta's scope of work also includes the construction of two HVDC Voltage Sourced Converter Stations (one in Arizona and one in New Mexico) and two AC Choppers in New Mexico, to be supplied by Hitachi Energy, a global technology leader and a leading provider of HVDC technology in North America. Preconstruction activities have begun, with construction expected to begin in the fourth quarter of 2023 and project completion expected to occur by the end of 2025.

Quanta expects to include the estimated revenues from the SunZia Transmission project in its Renewable Energy Infrastructure Solutions segment remaining performance obligations and backlog in the second quarter of 2023.

SunZia Wind
Located in Lincoln, Torrance and San Miguel Counties in New Mexico, the SunZia Wind project is a 3,500-megawatt wind generation facility designed to generate enough electricity to power the needs of more than 3 million consumers. Blattner Company was selected to provide comprehensive solutions for the wind farm facility and associated switchyard, which includes the installation of more than 900 turbines, ten substations, seven operations and maintenance facilities and a switchyard. Preconstruction activities have begun, with full construction expected to begin in the fourth quarter of 2023 and project completion expected by the end of 2025. Blattner's scope of work and execution plan for the SunZia Wind project leverages its prior success with building Pattern Energy's Western Spirit Wind project in New Mexico, which was completed in 2021 and, at that time, was the largest renewable energy project in the United States.

Quanta is performing various preconstruction activities for the SunZia Wind project under a limited notice to proceed contract and expects to include the estimated revenues for the project's full scope of work in its Renewable Energy Infrastructure Solutions segment remaining performance obligations and backlog by the third quarter of 2023.
