While many pipelines had holiday weekend restrictions in place to deal with extra-cold weather, it was a different situation for Florida Gas Transmission. Saying market area temperatures were forecasted to be mild and linepack was higher, FGT issued an Underage Alert Day notice Thursday with 20% tolerance for positive daily imbalances.

Tennessee said Thursday that due to colder weather in the Gulf Coast area, it might experience supply losses due to production-area wellhead freeze-offs. If that were to occur, the pipeline could be required to adjust the region’s Supply Aggregation Pools region as part of final scheduling for Cycle 1 nominations at 5 p.m. CST Friday. “In the event that pool adjustment is necessary, receipts into and deliveries from the pool will be adjusted to a tolerance of ± 100 dekatherms,” Tennessee said.

Northern Natural Gas kept a System Overrun Limitation notice that had been expanded to all market-area zones (ABC, D and E/F) Wednesday in place through at least Christmas Eve.
