Operational Flow Order (OFO)
An Operational Flow Order is a mechanism to protect the operational integrity of the pipeline. Pacific Gas and Electric Company's California Gas Transmission may issue and implement a System-Wide or Customer-Specific OFO in the event of high or low pipeline inventory. An OFO requires shippers to take action to balance their supply with their customers' usage on a daily basis within the specified tolerance band. Shippers may deliver additional supply, or limit supply delivered, to match usage. California Production Balancing Agreement holders must match scheduled nominations with actual daily production deliveries within the specified tolerance band.
