Chicago-based Invenergy is proposing to build four new wind farms and two solar farms to provide 700 megawatts of generation that would triple existing renewable energy available on Long Island. The project would be built across more than 55,000 acres in multiple states, located throughout the 12-state region of PJM, which is a regional transmission group. Four wind farms would have a capacity of 478 MW, and two solar projects would generate 223 MW. Power would be delivered by a buried high-voltage DC line that would end at a net-zero converter station in Long Island. Invenergy says the project is in response to a plan by New York Gov. Andrew Cuomo (D) to generate 50% of the state’s energy from renewable sources by 2030.
