Intraday

Upending the natural gas day will not solve the regional problems of lack of pipeline capacity and, in fact, will undermine the reliability of deliveries, the Natural Gas Supply Association (NGSA) said, responding to FERC’s proposed changes in gas scheduling aimed at serving electric power load (see Daily GPI, March 20).

Some opponents of exporting liquefied domestic gas argue that doing so would encourage more development of shale gas resources using hydraulic fracturing (fracking) well stimulation. Since fracking is bad (causes pollution), so are liquefied natural gas (LNG) exports, they argue. But that’s not how it works, FERC said in approving facilities proposed by Cheniere Energy Inc. units to liquefy and export gas from the Louisiana coast.

Southern California Gas did not extend a high-linepack OFO beyond Sunday’s Intraday cycle nominations. However, although the e-mail notice did not get sent until late afternoon Central time, it issued a new high-linepack OFO for Tuesday with a 10% tolerance for positive daily imbalances.

Southern California Gas sent a notice Wednesday morning declaring a high-linepack OFO effective with that day’s Intraday 1 nominations cycle. The tolerance for positive daily imbalances was set at 10%. The OFO was not extended beyond Wednesday.

Southern California Gas did not extend a two-day high-linepack OFO beyond Friday.

Southern California Gas said Saturday morning it was declaring a systemwide high-linepack OFO on the Intraday 1 nominations cycle for that day. The tolerance for positive daily imbalances was set at 10%. The OFO was continued through Sunday before being allowed to expire Monday.

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.

Southern California Gas waited until early morning to declare a high-linepack OFO on the Intraday 1 nominations cycle for Thursday, setting the tolerance for positive daily imbalances at 10%. The OFO will be kept in place through at least Friday.

Taking the rare step of issuing an OFO on the morning of its implementation, Southern California Gas (SoCalGas) declared a high-linepack OFO on the Intraday 1 nominations cycle for Wednesday. The giant LDC said it would assess Buy-Back charges in accordance with its rules and tariffs to customers who delivered more than 110% of their actual gas usage on the OFO day. The OFO was extended with the same conditions through Thursday.
