Pipeline balancing services are provided on California Gas Transmission's system by an allocated 5.0 Bcf of storage inventory, 200 MMcf/d of injection capacity, and 300 MMcf/d of withdrawal capacity. The current inventory of Imbalance Gas in Storage can be found on the Pipe Ranger Operations page.

Recent over-deliveries by suppliers have increased Imbalance Gas in Storage to a level that has reached the upper limit of 5.0 Bcf. As such, this will cause a suspension of pipeline balancing injection service beginning Friday, May 30, 2025.

Without the ability to inject for balancing, the likelihood of high inventory OFOs increases.

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 System Inventory Status information posted on Pipe Ranger.

Please call your CGT Representative if you have questions.
