Increase in Inventory Swing on December 1st
Tuesday, November 29, 2011
PG&E's California Gas Transmission is pleased to announce that, effective December 1, 2011, the available inventory swing to absorb fluctuations in supply and demand will increase from 200 MMcf to 450 MMcf. As was reported in early November, this increase is a result of CGT's ability to restore pressure on several critical backbone segments.
The increase in inventory swing is reflected on the "System Inventory Status" chart . The gray bands that represent "within operating limits" will now be between 3900 MMcf to 4300 MMcf on a day of lower system send-out and between 4000 MMcf to 4400 MMcf on a day of higher system send-out. Please note that CGT is in the process of modifying this chart to show increments of 50 MMcf, rather than 100 MMcf. As of December 1st, the true inventory bands used to determine if an OFO is necessary will be 3900 MMcf to 4350 MMcf and 4000 MMcf to 4450 MMcf, even though the chart is currently reflecting a slightly tighter set of bands.
With this increase in available inventory swing, we are also pleased to announce that we will cease calling high/low inventory OFOs as of gas day December 1st and return to our normal balancing provisions. We may still need to call the more traditional one-sided OFOs on any gas day, so please stay tuned to INSIDEtracc and Pipe Ranger for those notices.
CGT again thanks you for your great efforts in maintaining supply and demand balances during the five months of high/low inventory OFOs.
Please contact your CGT Account Services Representative with any questions.
