Pacific Gas & Electric extended into Sunday a Stage 3 high-inventory OFO that had been implemented Saturday, then expanded it Monday into a Stage 4 OFO with greatly increased penalties of $25/Dth for positive imbalances exceeding a 1% tolerance. No OFO was in effect Tuesday, but the utility reinstituted a Stage 3 order for today with $5/Dth penalties and an 8% tolerance.

Citing improved operating conditions, Tennessee lifted a systemwide OFO Balancing Alert Tuesday morning.

Northern Natural Gas did not extend a System Underrun Limitation notice beyond Monday.

Effective today, Northwest is lifting the Stage III Declared Overrun Entitlement that it had imposed at mid-month (see Daily GPI, May 15). However, Northwest said it “feels the entitlement mechanism is not assisting to alleviate the adverse operating conditions through the Kemmerer [WY] Compressor Station.” The pipeline plans to continue issuing an OFO “on a daily basis as needed.when the scheduled throughput north through Kemmerer exceeds the physical capabilities of the Kemmerer Compressor Station, including the capacity afforded by the portable compression. Northwest has not and does not anticipate moving any [storage] gas from Clay Basin to Jackson Prairie for its own account during this current OFO period.”

A customer tie-in to Tennessee‘s 509A-3100 Lateral offshore Louisiana, postponed earlier this month to May 18-22 due to the unavailability of divers (see Daily GPI, May 8), has been delayed again until June 3-7, the pipeline said Tuesday. Nominations will not be accepted at the Vermilion 200 and Vermilion 203 meters during the outage.

Effective Friday, NGPL will sell a number of offshore Louisiana laterals to Green Canyon Pipe Line; see the NGPL bulletin board for affected receipt and delivery points. Shippers doing business at those points will need to enter into gathering agreements with Green Canyon and nominate to that pipeline. Call Green Canyon’s Ron Fulcher at (832) 676-5625 for information.

ANR plans to conduct annual maintenance and upgrades June 25-29 to the motor control center and standby generators at its our E.G. Hill Compressor Station in the Texas Panhandle. Receipts from Duke Energy’s Sherman plant will be shut in by the work.
