Opal Plant operator Williams Field Services (WFS) said it was continuing to curtail Cycle 3 (Intraday 1) nominations for Wednesday's gas day after the Turbo Expander Plant 4 went down again (see Daily GPI, Nov. 3) after an attempted start at 5:45 p.m. MDT Tuesday. WFS said further investigation revealed the issue, and manufacturer Solar has located replacement parts that would be on site Wednesday. The new estimated time for restoring full Opal capacity was midnight Wednesday.
Effective Thursday Questar will lift an OFO restricting payback to the pipeline and will begin accepting nominations for in-kind imbalance paybacks to and from the pipeline. To minimize the possibility of the OFO being reinstated, "shippers and point operators should closely align scheduled nominations and actual production," the pipeline said.
Due to an outage downstream of the Tracy City Compressor Station and in order to maintain system operational integrity, East Tennessee Natural Gas is issuing a Balancing Alert OFO effective Thursday for LMSMA customers with meters between Tracy City and Topside. See the bulletin board for a list of affected meters.
Gulf South has rescheduled maintenance on all four units, one at a time, at the Jackson (MS) Compressor Station to begin Thursday and last through Nov. 12. The work previously had been set to start last Monday and continue for about seven days, possibly reducing capacity through the station by as much as 150,000 Dth/d. Gulf South said based on current system operations and nominations, it did not anticipate any impact to shippers but said that could change "at any time due to constantly changing operational conditions."
