Pacific Gas & Electric extended a systemwide high-inventory OFO through at least Wednesday; penalties were unchanged but the tolerance for positive daily imbalances was tightened slightly from 10% to 9%.

Northwest expressed appreciation for customers' cooperation in keeping northbound nominations through the Kemmerer (WY) Compressor Station bottleneck below 640,000 Dth/d to allow Northwest to move its balancing gas from Clay Basin to Jackson Prairie. "Adequate balancing gas in Jackson Prairie going into the winter heating season is critical to 1) provide reliable firm service on a peak day, 2) provide balancing flexibility to reduce the likelihood, levels and duration of potential entitlements, and 3) mitigate OFOs through Kemmerer," the pipeline said. It reported having been able to move approximately 450,000 Dth from Clay Basin to Jackson Prairie as of June 15. "However, Northwest must still move approximately 600,000 Dth to Jackson Prairie, on nonmaintenance days, prior to the end of September in preparation for the upcoming winter heating season," it added. "Overall, the vast majority of our customers have assisted in this task by increasing their Canadian supplies and voluntarily reducing primary nominations by approximately 11% or more through Kemmerer..." However, since the middle of May net banking on the system has increased by approximately 700,000 Dth, Northwest said, adding, "It is essential that Northwest retain its balancing gas and storage capacity for operational purposes, not for customer imbalance management. Therefore, customers north of Kemmerer need to closely manage and match nominations to actual deliveries. Drafting quickly erodes Northwest's balancing flexibility while banking takes away available storage capacity that needs to be reserved for Northwest's balancing gas. In addition, banking gives the appearance that Northwest's account within Jackson Prairie is growing at a faster rate than it actually is."

Southern California Gas will shut in its Goleta storage facility for 12 hours Wednesday to repair leaking flanges and for a blowdown of internal piping. This will cause a loss of 55 MMcf/d of injection capacity and 170 MMcf/d of withdrawal capacity that day.

A gas quality problem has been fixed at the BP-Sunray Plant receipt point in Moore County, TX, NGPL said. The point became available for flow again effective with the Intraday 1 nominations cycle for Tuesday's gas day.
