PG&E’s Injection Capacity Limited Due to Storage Maintenance

Friday, June 26, 2020

PG&E’s storage facilities maintenance has been scheduled for gas days, July 1st through 3rd. During this maintenance, California Gas Transmission is estimating a reduced injection capacity of 57 MMcf/day for the impacted gas days. All PG&E firm storage customer injections will likely be curtailed. PG&E does not anticipate any impact on deliveries to end-use customers.

Pipeline balancing services will continue to remain in effect under the regular protocols but at a reduced capacity of 57 MMcf/day of injection. As a reminder, beginning April 1, 2020, pipeline balancing service is an allocated 5 Bcf of storage inventory, 200 MMcf/d of injection capacity, and 300 MMcf/d of withdrawal capacity. PG&E balancing resources are only utilized during the gas intraday to manage the end-of-day pipeline inventory. Without the ability to fully inject for balancing, the likelihood of high inventory OFOs increases during this time period.

What can shippers do to help avoid high inventory OFOs?

Balance supply and demand daily. Work to ensure that supplies brought in for your customers balance with their daily demands.

Keep an eye on the Pipe Ranger Operations page for the System Inventory Status information and the current inventory of Imbalance Gas in Storage. To view each day’s maximum storage injection and/or withdrawal capacity, our PG&E Supply and Demand Forecast (Net Physical Flows) page on Pipe Ranger is a great resource.
