Although there was a false start Tuesday as Southern California Gas appeared to be ending a high-linepack OFO but waited until the afternoon to extend it another day, the utility will allow the OFO to expire Thursday.

Citing forecasts of high service-area temperatures and high linepack, MRT said it is issuing a System Protection Warning (SPW) effective with the start of Thursday’s gas day. See the bulletin board for SPW conditions.

Tennessee said a systemwide Imbalance Warning will take effect Thursday; it is asking customers to match physical flows with scheduled quantities to prevent imbalances that would threaten its operational integrity. “Due to continued mild weather, the long holiday weekend and storage field testing activity beginning Monday,” Tennessee said it does not have the ability to absorb imbalances caused by overdeliveries into the system by receipt point operators and undertakes from the system by delivery point operators.

Southern California Gas reported completing work to increase its long-term firm storage inventory by 2 Bcf, raising it to a total of 133.1 Bcf effective Thursday. The increase is being allocated as 1 Bcf to serve core customers and 1 Bcf to the unbundled storage program for sale to the marketplace, SoCalGas said.

Florida Gas Transmission (FGT) will start a scheduled three days of maintenance Monday at Compressor Station 11, during which three turbines at the station will be unavailable. FGT said it will schedule up to about 1,350,000 MMBtu/d through Station 11; there may not be any service constraints since the pipeline said current nominations there are around 1,300,000 MMBtu/d.

Noting that it had to delay previously scheduled integrity work on its Mississippi Chemical lines, Southern Natural Gas said based on its best available information the work now will begin Monday and continue through mid-May. Southern said it will be working on one line at a time, and the Mississippi Chemical delivery point can expect lower-than-normal operating pressures.
