Pacific Gas and Electric will end Friday a systemwide high-inventory OFO that had been in effect for the previous two days.

Williams Field Services (WFS) reported detecting a leak in the heat exchanger of Turbo Expander Plant (TXP) 5, a deep-cut cryogenic processing unit at its Opal Plant in Wyoming. While monitoring the leak, WFS will continue to operate TXP 5 until a repair crew can be on-site Tuesday. However, the company cautioned customers that the heat exchanger’s condition could change and cause WFS to take the unit down before the scheduled repair. Estimated impact from the planned maintenance Tuesday and Wednesday will be 350 MMcf/d.

Gulf South will begin three days of planned maintenance Tuesday on Unit #2 at the Carthage Compressor Station, during which station capacity could be reduced by as much as 40,000 Dth/d.

Noting that it had received authority from the Federal Energy Regulatory Commission in early August for the abandonment and sale of its Natural Buttes compressor station/processing plant facility to Chipeta Processing LLC, CIG said it expects to close the sale on or about Oct. 1. When that happens, the Uintah Meter Station 101, Saddle Draw and Coyote Wash receipt/delivery points will no longer be owned or operated by CIG, and thus the pipeline will no longer accept nominations at those locations. They will be replaced by the Anabuttes Meter Station at what will become the western terminus of CIG’s Uinta Basin Lateral. The current operational capacity of Anabuttes is 160.9 MMcf/d, CIG said.

Construction associated with the 2010 expansion project will require an outage due to tie-in activities associated with the installation of a new turbine and compressor at the Muddy Creek Compressor Station, Kern River said. For the duration of this event, which will begin Wednesday, three of the five units will be available. Based on historical flow patterns, the estimated operational capacity at Muddy Creek will be 1,348,000 Dth/d, a reduction from September’s average operational capacity of 1,615,000 Dth/d, the pipeline said. It encouraged customers to realign nominations downstream of Muddy Creek “in order to minimize capacity restrictions.”
