Joint Con Edison-Long Island Power Authority (LIPA) Offshore Wind Power Integration Project Feasibility Assessment

The study evaluated the necessary transmission reinforcement required for 350 MW and 700 MW of offshore wind generation. For up to 350 MW, a new transmission line from an onshore receiver station to an existing station in northern Queens, combined with a connection to the Long Island Power Authority (LIPA) transmission system in the vicinity of the Rockaways, would be optimal (at a total cost of $415 million). For a expanded facility up to 700 MW, it would be necessary to build new transmission lines from an onshore receiver station to a new substation in the vicinity of eastern Queens, combined with a connection to the LIPA transmission system in the vicinity of the Rockaways (for an additional $406 million).
