Novato, Calif., April 25, 2012 — Seven new solar photovoltaic power systems installed at city of Tucson facilities are coming online in Tucson, Arizona. The new 2.3 MW DC rooftop and carport solar power systems — developed by SPG Solar and interconnected by Tucson Electric Power — span downtown Tucson, including the Tucson Convention Center, providing combined $6.2 million net revenues over 25 years.
This project shows the city of Tucson's commitment to sustainability by providing the community with up to 60 green jobs during time of construction, two student internships and clean renewable energy. These latest projects build on Tucson's first phase of solar, which was 1 MW of solar — including both rooftop and single axis tracking systems — developed by SPG Solar in 2009.
SPG Solar capitalized on its design and engineering experience, providing the city with optimized rooftop and carport solar power systems at the Tucson Convention Center, Rincon Golf Links, Hardesty, Randolph, Crime Lab and two locations at TOPSC. The power generated at each site will offset, on average, 55 percent of the electricity used at each location.
TEP will provide financial incentives to the city of Tucson through the company's customer-funded large commercial solar program, which will reduce installation costs. The systems' output will help TEP work toward the renewable energy goals established by the Arizona Corporation Commission.
The latest 2.3 MW system will produce nearly 4 million kWh the first year, which is equivalent to powering 350 average American homes annually.
