A dropin off-system deliveries in TranscontinentalGas Pipe Line Co. LLC Zone 6 helped to keep spot prices lower year overyear during the week ended April 13, in spite of rising demand from the power sectorand gas utilities.

At Zone4, flows from interconnections with other pipelines climbed 14.7% versus the prioryear to 2.16 Bcf/d, driven primarily by a 263,463 Dth/d increase in flows from .

Residentialand commercial demand in Zone 5 jumped 67% to 1 Bcf/d, driven primarily by increasedflows to utilities serving customers in North Carolina.
TranscoZone 6 saw the lowest spot natural gas prices along the pipeline as prices declinedversus the year-ago week. At $1.729/MMBtu and $1.819/MMBtu, respectively, for Zone6 non-NY and Zone 6 NY, average spot prices were down 22.2% and 19%, respectively,below the year-ago week.
The dropin the zone's spot prices comes in spite of a 1.2% uptick in demand to 3.55 Bcf/d.Receipts from the midstream sector slipped 2.8% to 2.4 Bcf/d, and were offset bya 4.5% increase in supply from interconnected pipelines.
led the drop in midstream deliveries to Transco, but an increase in flows from helpedto cushion that decline as midstream deliveries fell 69,991 Dth/d year over year.
Meanwhile,increased deliveries from CentralNew York Oil and Gas Co. LLC and Columbia Gas Transmission LLC helped to boost supply despitedeclines at interconnections elsewhere in the zone.
Off-systemdeliveries fell 24.4%, the bulk of the decline being a 253,787 Dth/d drop in flowsto interconnections with NationalFuel Gas Supply Corp.
On balance,Zone 6 deliveries to local distribution companies, or LDCs, climbed 10.3%, led bya 236,973 Dth/d increase in flows to a group of points serving and National Grid USA.
Nearlyall deliveries to power generators took place in Zones 4, 5 and 6, with Zones 4and 5 together accounting for 73.5% of the week's average flows to the power sector,and Zone 6 accounting for the bulk of the remainder. Total system deliveries tothe power sector climbed 14.5% to 1.95 Bcf/d, as deliveries in Zone 4 dropped 15%and those of Zone 5 climbed 15.6%. Zone 6 deliveries to the power sector jumped61.7% to 503,085 Dth/d.
