The epic 3,000+ solar panel rooftop installation at the Brooklyn Navy Yard is now complete, Mayor Bill de Blasio announced on Monday. Installed by ConEdison, the sprawling solar array will contribute substantially toward the mayor’s OneNYC sustainability plan. The project, housed atop the Navy Yard’s Building 293, is just one piece of the city’s puzzle toward its 2025 goal of generating 100 megawatts of renewable energy on public buildings annually. The rooftop array is expected to generate 1.1 million kilowatt hours (kWh) of energy per year.

With 3,152 solar panels, the newly installed Brooklyn Navy Yard rooftop solar array is one of the largest in the city. The renewable energy generated is the equivalent of reducing carbon dioxide emissions by 1.4 million pounds and saving 76,000 gallons of gasoline each year. Placing such an enormous solar array at the Brooklyn Navy Yard was the result of careful decision-making, and spurred on in part by the booming developments in business at that site.

“We’re doubling jobs at the Navy Yard, and those workers, computers and machines will need sustainable energy. On rooftops across the city, we’re installing new solar panels to cut emissions, create green jobs and save money,” said de Blasio in a statement.

Brooklyn Navy Yard President and CEO David Ehrenberg reinforced the mayor’s comments. “As a home to 300 businesses and growing, we’re always looking for ways to be greener and more energy efficient,” he said. “The Yard is already on the cutting edge of technology and manufacturing, and with this solar installation we can now call the Yard a leader in renewable energy as well.”
