As a result of below normal temperatures in much of its market area thus far during March, Transco said, shippers have created a significant due-pipeline imbalance. The current forecast calls for a return to normal or above normal temperatures over the Easter holiday period, Transco added, and it is concerned that shippers “will attempt to resolve their current imbalance positions at a time when market loads are expected to be moderate.” The combination of warm temperatures and customers’ desires to pay back imbalances over a short time raises concerns about the pipeline’s ability to efficiently operate its system during the holiday weekend. To keep from having to issue an OFO or Operational Concern for the weekend, Transco asked that shippers with due-pipeline imbalances plan make-up transactions to resolve their imbalances ratably over the remainder of the month. Also, it will not schedule any excess storage injections over the March 25-28 period.

Dominion reported completing leak repairs in its TL-263 segment (see Daily GPI, March 22) and said all production required to be shut in by the work was being allowed to resume flow beginning at 4 p.m. EST Tuesday.

Gulf South began unscheduled maintenance Monday on Unit #3 at its Montpelier Compressor Station. The work will continue until further notice and could affect capacity through the station by as much as 75 MMcf/d, the pipeline said.

CenterPoint will begin taking Units #1, #2, #3 and #4 at Malvern (AR) Station down April 18 for an estimated five weeks of annual maintenance. IT and Secondary Firm transportation services to the NGPL Hot Springs and MRT Glendale interconnects will be restricted by an unspecified amount during this period.
