Longroad’s largest solar plus storage resource
Sun Streams 4 is Longroad’s largest solar and storage project to date and the first project Longroad has financed worth over $1 billion. The project’s total output, enough energy to power 120,000 homes, will be purchased by Arizona Public Service via a long-term Power Purchase Agreement.
Sun Streams 4 represents 625,000 metric tons of avoided CO2 emissions annually – the equivalent of taking approximately 140,000 gas-powered cars off the road for as long as the project operates. Numerous wildlife corridors allow wildlife passage, protecting native species habitats.
