Northern Natural Gas late Tuesday afternoon said it will implement a System Overrun Limitation Thursday for all market-area zones (ABC, D and EF). Compared to the pipeline's normal system weighted temperature of 25 degrees at this time of year, it projected that averages would fall from 28 Wednesday to 18 Thursday, 12 Friday and 13 Saturday.
With what is expected to be a prolonged winter storm having moved into the Pacific Northwest and Rockies, Northwest Pipeline declared a Stage III (13% imbalance tolerance) Overrun Entitlement for all Receiving Parties north of Kemmerer (WY) Compressor Station beginning Thursday. "This entitlement will apply to the mainline north of Kemmerer along with the Reno, Spokane, Wenatchee and Grants Pass laterals," Northwest said. The pipeline added that it aims to maintain operational flexibility during the cold front given reduced withdrawal capability at the Jackson Prairie storage facility, "which declines as the facility [working gas] balance decreases below 60%." The Stage III Entitlement is scheduled to continue through Monday.
Pacific Gas and Electric is ending a one-day systemwide low-inventory OFO Thursday.
Tennessee lifted Wednesday a meter-specific Balancing Alert OFO that it had issued for three locations a day earlier.
TransCanada said Wednesday it has extended the anticipated end date of an Emergency Operating Condition (EOC) -- declared Monday following a mainline explosion and fire Saturday night in northern Ontario (see Daily GPI, Feb. 23) -- through Friday. Until the EOC is lifted, the pipeline is not allowing any "discretionary services" through the impacted area, which currently has only one of three parallel lines in operation. According to Canadian newspaper reports Wednesday, TransCanada said it can not yet take spot gas shipments on its mainline due to the rupture, but the only one of three lines through the impacted area that is currently operational is moving 1.8 Bcf/d of contracted volumes. Shipments there had been in the 2.1-2.9 Bcf/d range in the week prior to the break, TransCanada was reported as saying.
