10/24/2014No OFO in Effect
10/25/2014No OFO in Effect

When an OFO or EFO has been called, customers' supplies are required to be within the tolerance requirement of daily usage to avoid noncompliance penalties. The criteria for complying with an OFO or EFO are described here.

For additional information, please contact the PG&E Scheduling Helpline at (800) 343-4743.

While updates to the OFO Outlook are posted here, customers should use INSIDEtracc as their primary source for OFO notification and updated information. For specific end-use customer information, please see INSIDEtracc.

All numbers are expressed in MMcf/day. When the forecast pipeline ending inventory exceeds the upper pipeline inventory operating limit or falls below the lower pipeline inventory operating limit, an OFO may be called to maintain the integrity and reliability of the gas transportation system.

Note: Historical data for yesterday is not available until mid-morning today.

*Forecast differences of less than 0 for the day after the current gas day (day 1) indicate that that PG&E may call an OFO to maintain pipeline integrity. Caution: This is PG&E's forecast of system inventory. Because market behavior and forecast loads can vary widely, this forecast may change significantly within the gas day and should therefore be used with caution. Forecasts further into the future are more likely to change than days closer to the current gas day e.g., the forecast for gas day 3 is subject to more change than the forecast for day 1.
All numbers are expressed in MMcf.
When an OFO has been called for the day after the current gas day (day 1), plans after the first plan of the gas day (posted by 8:30 AM) will often reflect changed market behavior and will show inventory projections within the established limits.

*Until yesterday's final figures are released, all numbers in this column will appear as 0.
** Suspension of pipeline balancing injection or withdrawal may occur if Imbalance Gas in Storage exceeds balancing inventory limits. If Imbalance Gas in Storage is greater than 4.040 Bcf, pipeline balancing injection may not be available. If Imbalance Gas in Storage is at or below 0.0 Bcf, balancing withdrawal will not be available.
The daily change of Imbalance Gas in Storage may not equal the daily Pipeline Balancing. This is because Pipeline Balancing is the entire system balancing required for the day and Imbalance Gas in Storage is only the Cumulative Imbalance portion of the entire system imbalance gas in storage. PG&E may include the entire system imbalance gas as the Imbalance Gas in Storage sometime in the future.
