PG&E Calif Gas unit warns on high natgas flows

NEW YORK, May 2 (Reuters) - Pacific Gas and Electric Co's (PCG.N: Quote, Profile, Research) California Gas Transmission on Friday issued an operational flow order for Saturday for all customers on its natural gas pipeline system due to high inventories.

The system-wide alert, issued at 11 percent tolerance, forces shippers to stay within 11 percent of their scheduled volumes in order to maintain system integrity, the company said in a website posting.

OFOs and other alerts protect the operational integrity of the pipeline by requiring shippers to take action to balance their supply with their customers' usage on a daily basis within a specified tolerance band.

CGT's 1,000-mile Line 300, with the capacity to transport about 1.1 billion cubic feet per day of supply, carries gas from several interstate pipelines to customers in California, while its 725-mile Lines 400 and 401 deliver Canadian and Rocky Mountain gas to the state with a peak capacity of about 2 bcf per day.
