CONSOLIDATED EDISON INC

Con Edison Transmission owns a 45.7 percent interest in New York Transco LLC (New York Transco), a New York limited liability company that was formed in November 2014 by affiliates of the four investor-owned electric utilities in New York, including Con Edison Transmission, to develop and own new electric transmission projects for the New York bulk electric system. Con Edison Transmission’s ownership interest in New York Transco is comprised of: (1) a 45.7 percent interest in New York Transco's Transmission Owner Transmission Solutions, a group of three electric power bulk transmission projects, (2) a 45.7 percent interest in New York Transco’s New York Energy Solution, an electric transmission project built to relieve transmission congestion between upstate and downstate New York, and a 41.7 percent interest in New York Transco’s share of Propel NY Energy, a proposed electric transmission project expected to deliver offshore wind electricity and increase high voltage transmission connections between Long Island and the rest of New York State.

Con Edison Transmission also owns a 71.2 percent interest in Honeoye Storage Corporation (Honeoye), a gas storage facility in upstate New York, with the remaining 28.8 percent held by CECONY. In addition, Con Edison Transmission owns a 7.9 percent interest (that is expected to be reduced to approximately 7.0 percent based on Con Edison Transmission’s previous capping of its cash contributions to the joint venture) in Mountain Valley Pipeline LLC, a joint venture developing a proposed 300-mile gas transmission project in West Virginia and Virginia.
