FERC has approved Dominion Transmission Inc.'s Clarington project, allowing it to build new compression facilities, interconnects and associated equipment to boost capacity on its mainline system by 250,000 Dth/d.

Dominion received its certificate of public convenience and necessity earlier this month, more than a year after it filed its formal application. The expansion is expected to be in service in late 2016 or after.

The project would allow Dominion to provide 250,000 Dth/d of incremental firm transportation service for Consol Energy Inc. The producer, which currently has more than 500,000 net acres in the Marcellus and Utica shales, signed a 15-year binding precedent agreement for the capacity in 2013.

Dominion would receive the additional natural gas from a new interconnect with Consol in Lightburn, West Virginia and deliver it to two other new interconnects in Monroe County, OH, with Texas Eastern Transmission (Tetco) and the Rockies Express Pipeline (REX).The Tetco interconnect would be called TET-Aram Hill and the REX interconnect would be called REX-German Ridge.

Dominion plans to construct a new 6,130 hp compressor and other equipment at its Burch Ridge Station in Marshall County, WV. It would also install two new 5,000 hp units at its Mullett Station in Monroe County, OH, two new meter stations and more than one mile of 16- to 20-inch diameter pipe to make the connections. The project is expected to cost about $76.6 million.
