"As a competitive energy company, our role is to give customers, like Owens Corning, greater flexibility in managing their energy use and costs," said Gary Fromer, senior vice president of distributed energy at Constellation. "Two years ago, we helped Owens Corning celebrate the completion of a 2.7-megawatt solar project at its facility in Feura Bush, New York. We are pleased to continue to invest with Owens Corning in our ongoing mutual commitment toward renewable energy and sustainable business operations."Employees and visitors to Owens Corning's headquarters can view energy output data from the system in real-time via a kiosk located in the lobby. Additionally, the parking canopy solar installation is equipped with two electric vehicle charging stations, which can charge up to four vehicles at a time. ChargePoint, a Constellation Technology Ventures portfolio company, supplied the stations. The solar power system is comprised of approximately 8,000 photovoltaic panels. The system is expected to generate 3 million kilowatt-hours of electricity per year (based on first year production). Generating the same amount of electricity using nonrenewable sources would result in the release of approximately 2,069 metric tons of carbon dioxide, or the equivalent emissions from 436 passenger vehicles annually, according to U.S. Environmental Protection Agency data for the region. Constellation currently owns and operates more than 300 megawatts of distributed energy projects that have been completed or are under construction for commercial and government customers throughout the United States. Constellation offers distributed energy solutions, including solar, cogeneration, backup generation, fuel cells, and battery storage, that may require no upfront capital from customers and may provide fixed power costs that are less than projected market rates.
