FERC has given the green light for CenterPoint Energy Gas Transmission to proceed with the construction of an expansion of its working gas capacity and deliverability at its storage facility in Oklahoma.
This came just weeks after the Federal Energy Regulatory Commission issued a certificate for CenterPoint Energy's so-called Chiles Dome Storage Expansion Project, which calls for the company to install and operate three additional injection/withdrawal wells and 23.4 miles of 24-inch diameter pipeline at its existing storage reservoir facility in Coal County, OK (see NGI, Aug. 1).
CenterPoint, a unit of Houston-based CenterPoint Energy Inc., plans to convert 3 Bcf of cushion gas to working gas capacity, increasing the facility's working gas volume to 15 Bcf, and boosting its withdrawl/deliverability rate by 43 MMcf/d to more than 300 MMcf/d [CP05-58].
The company estimates that the cost of the proposed construction will be approximately $25.6 million. FERC has given CenterPoint Energy two years from the date of the July 25 certificate order to complete construction of the storage expansion.
CenterPoint Energy's two interstate gas pipelines, CenterPoint Energy Gas Transmission and CenterPoint Energy-Mississippi River Transmission, form one of the largest natural gas pipeline networks in the Midcontinent (8,200 miles), carrying approximately 1 Tcf of gas each year.
