At the behest of customers, Kinder Morgan Inc.'s Sierrita Gas Pipeline LLC is holding a binding open season through Oct. 5 for potential expansion capacity, it said in a notice to cusotmers. Capacity would be made available with additional compression at the northern end of the pipeline near its interconnection with facilities of El Paso Natural Gas Co. LLC (EPNG). The expansion is expected to be sized between 230,000 Dth/d and 310,000 Dth/d, depending upon open season results. In-service could be as early as April 1, 2020. Capacity would be available from the San Joaquin Receipt Point at the interconnection with EPNG to the Sasabe Delivery Point at the U.S.-Mexico border. Capacity would be provided under Sierrita's Rate Schedule FT. Sierrita entered service last fall (see Daily GPI, Oct. 31, 2014). Mexico's demand for U.S. gas has grown significantly in recent years as the country's state-owned Petroleos Mexicanos has concentrated its limited resources on developing more lucrative oil reserves. Increasingly in Mexico, power is generated from burning natural gas.
