Longroad Energy, a prominent U.S.-based renewable energy developer, owner, and operator, has announced the successful financial close of its Serrano project. Located in Pinal and Pima Counties, Arizona, Serrano comprises a 220 MWdc solar array paired with a 214 MWac / 855 MWh energy storage facility. This marks Longroad’s inaugural project utilizing First Solar’s domestically manufactured Series 7 panels. Construction has commenced, with commercial operations slated for mid-2025.

Arizona Public Service (APS) has inked a long-term Power Purchase Agreement (PPA) to procure the output from Serrano. The project is anticipated to provide electricity for approximately 61,000 Arizona households, aiding grid stability, especially during peak summer demand.
