Due to anticipated colder temperatures and in order to maintain its linepack, Tennessee said an OFO Action Alert would take effect Saturday for all LMS-MA Balancing Parties with meters in Zones 5 and 6. Affected shippers are required to maintain an actual daily flow rate not exceeding 2% or 500 Dth, whichever is greater, of scheduled quantities. Penalties of 21.98 cents/Dth will be assessed for exceeding the tolerance.

Northern Natural Gas said Friday a System Overrun Limitation for the New Market, MN, #1 Town Border Station would be in effect for the gas days of Saturday through Monday.

With forecasts for Wisconsin (ML-7 zone) beginning Sunday and continuing into this week projecting temperatures near or below zero, ANR declared an Extreme Condition that lowers its Swing Percentage (imbalance tolerance) from 10% to 5%. In addition, ANR said it is not allowing any Unauthorized Overrun under Rate Schedules FTS-1, FTS-2, FTS-3, FTS-4, FTS-4L, STS and ETS.

Dominion added an FTNN [Firm Transportation No-Notice] Hourly Limit OFO, effective Friday until further notice, for 13 Virginia and Maryland utility/pipeline meters in its PL-1 market area to the one it had issued Thursday (which also took effect Friday) for seven utility meters in New York (see Daily GPI, Dec. 19). OFO conditions were essentially the same in each case. Dominion also added a “Conform Transportation Services to Scheduled Nominations” OFO #2 for the PL-1 area; that OFO went into effect Saturday.

Pacific Gas & Electric did not extend a systemwide Stage 2 high-inventory OFO beyond Friday.

With anticipated high weekend market demands from much colder weather combined with high firm transportation load factors, CIG said it “is concerned that our ability to absorb imbalances related to underdeliveries (drafts) at receipt points or overpulls (drafts) at delivery points will be limited to a significant degree. CIG expects operators to continuously manage their confirmations to match actual flow rates, factoring in freeze-offs and other conditions as necessary, particularly while the cold weather impacts field and pipeline operations…Over the weekend, CIG will allow unlimited gas ONTO our system and no paybacks to go OFF system.”

TransCanada reported that TransQuebec & Maritimes (TQM) had returned Unit A2 at Station #650 (Lachenaie) to service Thursday night, and TransCanada began accepting increased nominations for deliveries to East Hereford and GMi EDA for the Intraday 1 cycle of Friday’s gas day. TQM had experienced a multiple compressor failure at the station Dec. 13 (see Daily GPI, Dec. 18). TransCanada said firm service likely would be fully authorized, but due to operational considerations from the remaining compressor outages, it anticipated that “all discretionary service may continue to be restricted.”
