Arizona Gov. Katie Hobbs, Arizona Corporation Commissioner Lea Marquez Peterson and executives from Arizona Public Services (APS), McCarthy Building Cos. and U.S. Bancorp Impact Finance attended Longroad Energy’s ribbon cutting at the Longroad Sun Streams Complex in Maricopa County.
The event celebrated progress made so far at the more than 6,000-acre solar and storage complex, a combination of three projects that together are set to deliver enough solar energy to power 200,000 homes.
The two largest projects in the complex, Sun Streams 3 and Sun Streams 4, have been purchased by APS via long-term power purchase agreements and will help support system reliability in Arizona, particularly during the peak demand period of the summer months. McCarthy, which has a renewable energy team based in Phoenix, has been the engineering, procurement and construction contractor for the three projects in the Longroad Sun Streams Complex.
When completed, the complex will include more than 950 MWdc of solar and 600 MWac or 2500 MWh storage. All three projects utilize modules from Arizona-headquartered First Solar and trackers from Nextracker. The battery energy storage systems at both Sun Stream 3 and Sun Stream 4 are provided by Powin, with comprehensive operations and maintenance services for Longroad’s three projects to be provided by Arizona-based Novasource.
The Sun Streams 3 battery yard, which is nearing completion, spans more than 15 acres, with approximately 1 million battery cells currently being installed. Together, Longroad Streams says its three Longroad Sun Streams projects represent 1.4 million metric tons of avoided carbon dioxide emissions annually, or equal to the amount of carbon dioxide that would be generated by four natural gas-fired power plants.
