Williams Partners LP is holding a binding open season through June for capacity on its proposed Northeast Supply Enhancement Project, which would expand the Transcontinental Gas Pipe Line Co. (Transco) system to serve northeastern markets (see Daily GPI, May 12). The additional capacity would enter service for the 2019-2020 winter heating season. The project is being designed to provide 400,000 Dth/d of firm capacity from Transco's Compressor Station 195 in York County, PA, to the Rockaway Transfer Point, an existing interconnection between the Lower New York Bay Lateral and the Rockaway Delivery Lateral offshore New York state. National Grid is the first to take capacity in the project, which would consist of additional looping and compression on existing Transco facilities.
