Longroad Energy, a U.S. based renewable energy developer, owner and operator, has closed financing and started construction on Sun Streams 4, a 377 MW DC PV and 1,200 MWh storage project.

Sun Streams 4 is Longroad’s largest solar and storage project to date and is the company’s third project in its Sun Streams complex, based in Maricopa County, Ariz. Commercial operations for Sun Streams 4 is currently expected by mid-2025.

During the construction period, Sun Streams 4 is expected to employ over 200 people. McCarthy Building Companies was selected as the engineering, procurement and construction contractor.

Sun Stream 4’s total output, enough to power 120,000 homes, will be purchased by Arizona Public Service (APS) via a long-term PPA. The project will help support system reliability in Arizona, particularly during the peak demand summer months.

“A landmark project for us, Sun Streams 4 has the distinction of being Longroad’s largest project to date by both megawatts and investment capital, and one of our first projects to incorporate provisions from the historic Inflation Reduction Act,” says Paul Gaynor, CEO of Longroad Energy.

The project is part of the Sun Streams portfolio that Longroad acquired from First Solar in early 2021.

Debt financing was led by CIBC and included ANZ, PNC, BNP Paribas, Commerzbank AG, CoBank, U.S. Bancorp Impact Finance, National Australia Bank and Société Générale.
