After lifting the rest of an OFO Action Alert for its six furthest upstream zones Tuesday, Tennessee said a new one with systemwide impact would be implemented Sunday. It cited limited operational flexibility, mild weather and upcoming Hebron/Ellisburg storage field tests as reasons for the OFO, which requires affected shippers to not exceed a tolerance of 2% of scheduled quantities or 500 Dth, whichever is greater, for overdeliveries into the system and undertakes from the system.
Citing projections of high storage injection requirements for the weekend, Southern said Friday it was implementing an OFO Type 6 for long imbalances effective Saturday until further notice. Tiered penalties will apply to customers who exceed specific tolerance ranges for long imbalances.
Pacific Gas and Electric kept a systemwide Stage 2 high-inventory OFO in place through at least Saturday and slightly tightened the tolerance for positive daily imbalances from 12% to 11%.
Florida Gas Transmission ended Friday an Overage Alert Day that had been in effect for the previous three days.
CIG said it has again evaluated the Strained Operating Condition (SOC) that was initiated Sept. 1 and will cancel the SOC Monday along with all remaining associated limitations.
Saying a noise control project at Blue Mound Compressor Station was progressing ahead of schedule, Rockies Express (REX) reported completing work on three of the five compressor units late Thursday night. REX said it expected to finish work on the remaining two units sometime Saturday, with full service through Segment 320 restored for Sunday's gas day. Effective with Intraday 1 Cycle nominations for last Friday and until further notice, capacity through Segment 320 will be limited to 1,790,000 Dth/d, the pipeline added. AOR/IT, secondary and primary quantities continue to be at risk of not being fully scheduled.
Southern said an engine maintenance project at Bell Mills Compressor Station in northeast Alabama had one unit scheduled to return to service during the first week of November, but that date had "slipped" until around Nov. 16. Southern doesn't expect the delay to impact firm deliveries, but said small amounts of interruptible capacity and Southern's ability to deliver quantities in excess of hourly entitlements could be impacted if cold temperatures arrive before the return-to-service date.
