Platts to review Transco, zone 2 natural gas price index methodology

Platts, part of S&P Global Commodity Insights, is entering a formal period of market consultation to review its Transco, zone 2 (IGBBU00) natural gas index methodology.

Platts has observed a pricing disparity between trades done at the Transco Zone 2 Station 45 pooling point and trades done at other locations within Zone 2, such as the Clarks Branch interconnect between Transco and Matterhorn Express Pipeline. Trades not done at the Station 45 pooling point tend to price lower, resulting in exclusion from the Transco, zone 2 natural gas daily index.

Platts invites market feedback on the existing Transco, zone 2 index methodology to determine whether a change is warranted to allow for wider inclusion of reported trades in the Transco, zone 2 natural gas index.

Please send any feedback to AmericasGasPricing@spglobal.com and pricegroup@spglobal.com by June 20. Any feedback not marked as confidential may be made available for public viewing upon request.
