The Departments of Citywide Administrative Service and Environmental Protection today announced an innovative solar power public-private partnership to reduce the Cityâ€™s carbon footprint, improve air quality, and increase the reliability of the electricity grid, particularly during the hottest months of the year. Tangent Energy Solutions, a private energy services company, will install solar arrays totaling more than 1.85 megawatts on the roofs of four City buildings in Staten Island and the Bronx. Together, the solar installations will produce more than 2 million kilowatt hours of electricity annually â€“ enough to power 245 residential homes â€“ decrease greenhouse gas emissions by 1,636 metric tons a year and help reach the Cityâ€™s PlaNYC goal of reducing its emissions of greenhouse gas by 30 percent by 2030. In addition, under the program, which comes with no upfront capital cost, the City will not be responsible for purchasing, owning, installing or maintaining the system, and can purchase the electricity generated from it. As a result, the City is set to save more than $8 million compared to the cost of installing the solar systems through its capital construction program, and the four projects will help bring more than 40 new green jobs to the city and pave the way for more similar projects â€“ both public and private.
