Evenas overall demand climbed year over year during the week ended May 4, spot naturalgas prices along TranscontinentalGas Pipe Line Co. LLC sank as off-system deliveries helped to offsetincreased gas utility demand.

Duringthe week, deliveries in zones 4, 5 and 6 accounted for 80.7% of system demand, whilereceipts in zones 3, 4 and 6 accounted for 85.1% of supply coming on to the system.Alone, Zone 6 accounted for 51.4% and 42.2% of the week's average supply and demand,respectively.
Zone3 saw the week's average supply decline 32.5% to 652,944 Dth/d, as receipts frominterconnected pipelines declined 31.5% to 454,313 Dth/d, led by a 94,454 Dth/ddecline in flows from Garden BanksGas Pipeline LLC.
Duringthe week, Zone 3 spot natural gas prices averaged $1.862/MMBtu, down 27.5% fromthe year-ago level of $2.570/MMBtu.
At Zone4, flows from interconnections with other pipelines were nearly flat year over yearat 2.01 Bcf/d, as flows from TennesseeGas Pipeline Co. declined entirely to help offset increased flows elsewhere.
Zone4 off-system deliveries more than doubled to 187,323 Dth/d, driven primarily bya 171,413 Dth/d increase in flows to ElbaExpress Co. LLC.
Spotprices in the zone were down 27.5% year over year to an average of $1.869/MMBtu,a 0.7-cent premium to Zone 3.
Similarly,spot prices in Zone 5 averaged $1.931/MMBtu, a 26.7% decline from the year-ago week,but a 6.2-cent premium to Zone 4.
Off-systemdeliveries in the zone climbed 119% year over year to 344,952 Dth/d, driven largelyby a 116,828 Dth/d increase in deliveries to the Elba Express pipeline.
Residentialand commercial demand in Zone 5 climbed 6.7% to 671,700 Dth/d, with the largestyear-on-year variations in flows seen at gas utilities in Virginia and North Carolina.
TranscoZone 6 saw the lowest spot natural gas prices along the pipeline as prices declinedversus the year-ago week. At $1.545/MMBtu and $1.596/MMBtu, respectively, for Zone6 non-NY and Zone 6 NY, average spot prices were down 39.3% and 37.9%, respectively,below the year-ago week.
The dropin the zone's spot prices comes in spite of an 8.2% increase in demand to 3.2 Bcf/d.Receipts from the midstream sector climbed 11.8% to 2.24 Bcf/d, while deliveriesfrom interconnected pipelines edged 0.9% lower to 1.59 Bcf/d.
and Williams Field Services Co. LLCled the increase midstream deliveries to Transco.
Meanwhile,a 100,500 Dth/d increase in supply from TennesseeGas Pipeline Co. and a 35,651 Dth/d increase in flows from wasoffset by a reduction in flows elsewhere.
The zone'soff-system deliveries declined 40.2% to 726,096 Dth/d, the bulk of which was a 330,446Dth/d drop in flows to interconnections with Dominion Transmission Inc.
Zone6 deliveries to local distribution companies, or LDCs, jumped 44.2% to 1.77 Bcf/d,driven primarily by a 531,613 Dth/d increase in flows to a group of points servingConsolidated Edison Co. of New YorkInc. and National GridUSA.
Nearlyall deliveries to power generators took place in zones 4, 5 and 6, with zones 4and 5 together accounting for 78.3% of the week's average flows to the power sector,and Zone 6 accounting for the bulk of the remainder.
