Platts launches two new US monthly natural gas indices

S&P Global Platts has added two new locations to its suite of monthly natural gas indices in the US, specifically Northwest, S. of Green River (IGBYT03) and Northwest, Wyoming Pool (IGBDA03), effective Dec. 27, the first day of January bid week.

This launch follows from a decision published Oct. 28 and available here: https://www.spglobal.com/platts/en/our-methodology/subscriber-notes/102821-platts-to-launch-two-new-us-monthly-natural-gas-indices

Platts has observed that the southern portion of the Northwest, Rocky Mountains trades at a discounted price to the northern portion in the monthly market. The newly launched indices will allow Platts to more accurately capture this price divergence.

Platts has already been reflecting these locations in its daily indices.

NORTHWEST, S. OF GREEN RIVER MONTHLY: Deliveries into Northwest Pipeline from the Green River, WY compressor station south to the La Plata interconnection with El Paso Natural Gas in the San Juan Basin in La Plata County, CO. Included are deliveries from Clay Basin storage, the Piceance Basin and the Ignacio plant.

NORTHWEST, WYOMING POOL MONTHLY: Deliveries into Northwest Pipeline from the Green River, WY compressor station to the Kemmerer, WY station. Included are deliveries at the Opal, WY plant, as well as at the Painter, Anschutz, Muddy Creek, Granger, Shute Creek and Whitney stations.

The methodology for the existing Northwest Rocky Mountains monthly index remains unchanged.

The new indices are published on Platts real-time alert's pages NG1315, NG1323, NG1431 and NG1426-NG1428, in the Americas Gas Service of Platts Dimensions Pro, in the Inside FERC Gas Market Report First of Month publication, and via market data.
