MCN Investment Corp. and Tennessee Gas Pipeline Co. plan to build a $45-million liquified natural gas plant near the Delaware-Maryland border. The project, named Continental States Peaking Services L.L.C., would liquify, store and vaporize gas beginning in early 2000. It would connect to the Eastern Shore Natural Gas pipeline system, with access to the Transcontinental Gas Pipe Line and Columbia Gas Transmission system. The facility could provide as much as 2 billion cubic feet equivalent of gas storage service, or peak-day withdrawal capacity of up to 200 million cubic feet per day of revaporized gas. The project's size, capacity and feasibility will depending on the results of the project's open season, which ended July 25. FERC approval would follow.
