A day after lifting Thursday’s systemwide Stage 2 high-inventory OFO, Pacific Gas & Electric declared an identical OFO for Saturday that again carried penalties of $1/Dth for positive daily imbalances exceeding a 5% tolerance.
Gulfstream canceled Thursday the Action Alert that it had issued the day before due to high linepack.
After evaluating preliminary geotechnical survey results regarding land movement that affected its 26-inch and 30-inch diameter mainlines east of Centralia, WA (see Daily GPI, Oct. 28), Northwest said initial analysis indicates that pipe was damaged. Saying the land is currently stable, Northwest plans to begin replacement work Tuesday and anticipates that it will take two to three days to complete. During this outage there will be no physical flow through the Chehalis Compressor Station. “To the extent possible, Northwest will work with its interconnecting pipelines and use system balancing to mitigate impacts to its customers,” Northwest said. See the bulletin board for details on the mitigation efforts.
Transwestern, which cut the capacity of WT-2 Compressor Station near Kermit, TX to 500,000 MMBtu/d last Tuesday for a maintenance project and was scheduled to return the station to full capacity of 615,000 MMBtu/d Nov. 6 (see Daily GPI, Oct. 26), said Friday the restriction will resume Nov. 7-11 for maintenance on the station’s 24-inch mainline suction pipe. Ten points on the West Texas Lateral will be affected again. Full capacity is now set to be restored Nov. 12. (Note: An earlier posting on the current curtailment had said full WT-2 capacity was 600,000 MMBtu/d. A spokeswoman explained that 600,000 MMBtu/d was correct, but the station’s capacity will be raised to 615,000 MMBtu/d effective Nov. 1. Also, the latest Transwestern posting indicates that the current work will end Nov. 3 instead of Nov. 5 and that full capacity now will be restored on Nov. 4.)
Based on its own analysis and feedback from customers, Questar said it has developed a proposal to provide an expanded service to its shippers that addresses gas quality issues and provides additional options. The pipeline will present that proposal to shippers in a meeting to be held Thursday in Denver. Call DeAnna Brunette at (801) 324-5173 for more information about the meeting. As part of its proposal, Questar plans to designate wet and dry segments or “zones” on its system. Wet zones will have liquid handling facilities that allow Questar to manage condensing hydrocarbon liquids from wet hydrocarbon dew point volumes. Dry zones will be segments in which no free or condensing liquids will be permitted.
