Columbia Gulf Files First Expansion Since 1971
Columbia Gulf Transmission filed a request with FERC last week
for authorization to expand its mainline for the first time since
1971. The filing requests authorization to provide 315,000 Dth/d of
firm capacity to 19 shippers, 14 of which will be new to the
system. Most of the service requests would be provided with
existing capacity. An expansion project would increase Columbia's
current throughput capability by 100,000 Dth/d through the addition
of new compression.
The expansion is necessary to meet the "demand pull" that's
expected in Columbia Energy's market area in the Mid-Atlantic
states and in the Northeast, said Catherine G. Abbott, president
and CEO of Columbia Gas Transmission and Columbia Gulf
Transmission, at the Process Gas Consumers' third annual conference
in Baltimore, MD, last Thursday.
The company is projecting a demand hike of 4.2 Bcf/d in the
Northeast by 2010, with more than half going to the electric
sector. This would be on top of the 3 Bcf/d increase in gas usage
in the Northeast during the last decade, Abbott told industrial gas
An open season late last year for Columbia's Mainline '99
expansion yielded requests for 315,000 Dth/d. About 12,000 Dth/d
that was turned back by existing shippers also will be used to
serve the new requests. Columbia Gulf President Terrance L. McGill
said 63% of the capacity was awarded to marketers, 27% was awarded
to local distributors and 10% went to industrial customers.
Columbia said it plans to expand the 2,400-mile system through a
two-phase installation. About 35,000 hp of compression will be
added in 1999 and 15,000 hp in 2000 at existing compressor stations
located at Inverness and Corinth, MS, and at Hampshire, TN.
Columbia Gulf's mainline system stretches from Rayne, in South
Central Louisiana to the Kentucky-West Virginia border, south of
Ashland, KY. It connects Gulf Coast supplies to markets in the
South, as well as the Midwest, East and Northeast areas of the
