Colorado Interstate Gas applies for 230-MMcf/d expansion project

Colorado Interstate Gas Co. LLC asked the Federal Energy Regulatory Commission for authorization to modify compressor stations to provide 230 MMcf/d of additional firm natural gas transportation service to a hub in Colorado.

The Kinder Morgan Inc. company applied for the project on Feb. 27 under the blanket authorization of a Natural Gas Act certificate. Colorado Interstate Gas would provide about 180 MMcf/d of the additional transportation capacity to DCP Midstream Marketing LLC. The developer said the 50 MMcf/d of unsubscribed expansion capacity would be available for other shippers.

The estimated cost of the project is $14.5 million. The targeted in-service date is Oct. 1.

Colorado Interstate Gas said it would modify its CIG Cheyenne, CIG Cheyenne Jumper and CIG Front Range Jumper compressor stations at the Cheyenne hub complex in Weld County, Colo. The modifications would provide the additional gas transportation from mainline receipt points along the Colorado Front Range of the Rocky Mountains to the hub. The hub complex is owned and operated by Colorado Interstate Gas, Cheyenne Plains Gas Pipeline Co. LLC and Wyoming Interstate Co. LLC.

The modifications would allow Colorado Interstate Gas to increase its mainline northbound transportation capacity from 315 MMcf/d to 545 MMcf/d, and also allow for additional bidirectional transportation capacity. In addition, the delivery capability into the high-pressure pool at the Cheyenne hub would increase from 255 MMcf/d to 505 MMcf/d, the company said.

Colorado Interstate Gas' pipeline transmission system extends from supply areas in Texas, Oklahoma, Kansas, Colorado, Wyoming, Montana and Utah to major delivery areas along the eastern slope of the Rocky Mountain Front Range in Colorado and Wyoming. (FERC docket CP18-94)
