Dominion told shippers that effective with the start of Tuesday’s gas day, there will be no interruptible or secondary capacity available at the following delivery points until further notice: Corning Natural Gas, New York State Electric and Gas, Rochester Gas & Electric, Niagara Mohawk, Fillmore Gas and National Fuel Gas Distribution. Dominion said the reason for this action is “due to the anticipated weather forecasts [and] the duration of these forecasts, as well as the anticipated corresponding firm load requirements.”

Columbia Gas said it had deemed the gas days of Jan. 15-18 to be a “Critical Day” in 27 market areas (see the bulletin board for details). The pipeline had projected that all available capacity to those areas would be required to meet firm service obligations, leaving zero nonfirm capacity for them. Based on storage withdrawal capacity and on forecasted firm storage requirements, Columbia said it expected that no excess withdrawal capacity for SIT service, imbalance drawdowns, ISS withdrawals, and PAL lends/unparks would be available.

Westcoast reporting experiencing low linepack Friday due to “various production upsets” (which a producer told NGI were the result of wellhead freeze-offs in British Columbia). Expecting that linepack would drop below 2,650 MMcf by the end of Friday’s gas day, Westcoast said if it observed Saturday that production has been lost, the affected shipper’s business “will be reduced to the production that can be confirmed.” It also said it would review individual shipper accounts “and may adjust account availabilities for those shippers that have business in excess of verified production.”

Due to forecasted cold weather and heavy demand, and to preserve system reliability, East Tennessee Natural Gas issued two Action Alert OFOs that were due to take effect Monday until specifically lifted by ETNG. See the bulletin board for details on the OFOs.

Due to restrictions affecting volumes pathed through Station 47 and to ensure that customers’ deliveries and receipts are matched, Tennessee planned to adjust the 100 Leg Supply Aggregation Pools in Zones 0 and 1 as part of final Cycle 1 scheduling Friday to a tolerance of plus-or-minus 100 dekatherms.
