FERC last week issued a certificate to CenterPoint Energy Gas Transmission to expand the working gas capacity and deliverability of its storage facility in Oklahoma.
CenterPoint Energy plans to install and operate three injection/withdrawal wells and 23.4 miles of 24-inch diameter pipeline at its Chiles Dome Storage Reservoir facilities in Coal County, OK.
The project calls for CenterPoint Energy to convert 3 Bcf of cushion gas to working gas capacity, increasing the facility's working gas volume to 15 Bcf, and to increase its withdrawal/deliverability rate by 43 MMcf/d to more than 300 MMcf/d.
CenterPoint Energy said its four local distribution company affiliates in Arkansas, Louisiana, Oklahoma and Texas were the only shippers to express an interest in the storage capacity, and each has executed a seven-year contract.
The company, a unit of Houston-based CenterPoint Energy Inc., estimates that the cost of the proposed construction will be approximately $25.6 million.
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.
