Transwestern Expansion In Service
Construction is complete, and Transwestern Pipeline Co. has
increased its available capacity to California by 15%, a move
providing expansion shippers with opportunities to move incremental
volumes from the San Juan and Permian Basins to the California
border. The $12 million project was approved by FERC in mid-January
(see NGI, Jan. 17, 2000).
Transwestern's approach to boosting its pipeline capacity
included the installation of a 10,000 hp motor to run the new
compressor station near Gallup, NM, and the addition of gas coolers
at the La Plata "A" compressor station at Ignacio, CO, and
Bloomfield, NM. The in-service date was May 1, according to company
The expansion is expected to allow Transwestern to maintain its
mainline operating pressure from Thoreau west to California at 950
psig at all times, enabling it to better accommodate shifts in
market demand to the east without restricting delivery capacity to
California. With this move, Transwestern will be able to once again
operate its mainline west of Thoreau at its certificated capacity
of 1.09 Bcf/d on a firm basis, and meet its demand for gas on the
eastern portion of its system. This includes delivery of 750 MMcf/d
to Needles, CA, and 340 MMcf/d to Topock, AZ.
The cooling equipment is expected to create an additional 50,000
Mcf/d of incremental firm capacity on the Blanco-to-Thoreau segment
of the San Juan lateral, according to company officials.
Six shippers contracted with Transwestern for the 140,000 Mcf/d
of capacity created by the Gallup expansion, including Southern
Energy, Sempra Energy Trading, North Star Steel, Duke Energy
Trading and Marketing, Reliant Energy Services and El Paso Energy
Marketing. The transportation contracts are for five years, except
for North Star Steel and El Paso Energy Marketing.
According to FERC, the Gallup expansion is not expected to
affect the take-away capacity of downstream shippers and "will not
result in Transwestern transporting more gas than its certificated
capacity level." FERC said the expansion would allow the company to
provide the level of service it already has been authorized to do
for "Needles to Topock."
