Liberty Wind proposes to deliver up to 1,200 megawatts of offshore wind power to New York. The Liberty Wind proposal includes 400 megawatt, 800 megawatt and 1200 megawatt project size options. The 1200 megawatt project is the most cost-effective option for New York ratepayers. The Liberty Wind 1200 megawatt project would supply enough emission free energy to power over 750,000 New York homes. Learn more at
