Onthe supply side, a 922,725 Dth/d increase in receipts from interconnectedinterstate and intrastate pipelines more than offset a 660,869 Dth/d decline innet receipts from the upstream and midstream sectors, leading to a net increasein supply year over year.
Duringthe week, deliveries in Zones 4, 5 and 6 accounted for 81.3% of system demand,while receipts in Zones 3, 4 and 6 accounted for 86.1% of supply coming on tothe system. Alone, Zone 6 accounted for 48.9% and 42.4% of the week's averagesupply and demand, respectively.
Zone3 saw the week's average supply climb 8.4% to 834,180 Dth/d, as receipts frominterconnected pipelines jumped 42.8% to 628,819 Dth/d, led by a 122,373 Dth/dincrease in flows from ANRPipeline Co.
Duringthe week, Zone 3 spot natural gas prices averaged $1.855/MMBtu, down 28.6% fromthe year-ago level of $2.598/MMBtu.
AtZone 4, flows from interconnections with other pipelines climbed 29.6% versusthe prior year to 2.37 Bcf/d, driven primarily by a 287,604 Dth/d increase inflows from Midcontinent ExpressPipeline LLC.
Zone4 off-system deliveries more than doubled to 200,092 Dth/d, driven primarily bya 181,400 Dth/d increase in flows to ElbaExpress Co. LLC.

Off-systemdeliveries in the zone climbed 81.6% year over year to 331,390 Dth/d, drivenlargely by a 93,842 Dth/d increase in deliveries to the Elba Express pipeline.
Residentialand commercial demand in Zone 5 jumped 35.5% to 877,041 Dth/d, as more thanhalf of the week's flows went to PiedmontNatural Gas Co. Inc. and PublicService Co. of North Carolina Inc.
TranscoZone 6 saw the lowest spot natural gas prices along the pipeline as pricesdeclined versus the year-ago week. At $1.633/MMBtu and $1.701/MMBtu,respectively, for Zone 6 non-NY and Zone 6 NY, average spot prices were down30.2% and 29.7% below the year-ago week.
Thedrop in the zone's spot prices comes with a 6.5% drop in demand to 3.38 Bcf/d.Receipts from the midstream sector dropped 6.7% to 2.28 Bcf/d, and a 0.4%increase in deliveries from interconnected pipelines failed to offset thatdecline.
led the drop in midstream deliveries to Transco as flows from the midstreamoperators dropped 164,770 Dth/d collectively.
Meanwhile,the zone saw roughly offsetting changes in flows from interconnected interstatepipelines as nominations ticked 6,721 Dth/d higher year over year.
Leadingthe drop in Zone 6 demand was a 30.1% drop in off-system deliveries, the bulkof which was a 200,772 Dth/d drop in flows to interconnections with
Onbalance, Zone 6 deliveries to local distribution companies, or LDCs, edged 0.7%higher, led by a 192,881 Dth/d increase in flows to a group of points servingConsolidated Edison Co. of NewYork Inc. and NationalGrid USA that offset declines in flows to
Nearlyall deliveries to power generators took place in Zones 4, 5 and 6, with Zones 4and 5 together accounting for 76.7% of the week's average flows to the powersector, and Zone 6 accounting for the bulk of the remainder. Total systemdeliveries to the power sector slipped 4.8% to 474,762 Dth/d in Zone 4, whilethey climbed 32.1% to 1.03 Bcf/d in Zone 5. Zone 6 deliveries to the powersector jumped 40.3% to 446,940 Dth/d.
