Platts changes Transco, zone 5 delivered South methodology, launches new Transco, Station 165 index

Platts, part of S&P Global Commodity Insights, has changed the methodology of the Transco, zone 5 delivered South daily (IGCHL00) and monthly (IGCHL03) natural gas indices to exclude transactions at Station 165 for flow in July 2024. Platts has also launched a new Transco, Station 165 daily (IGBYZ00) and monthly (IGBYZ03) natural gas index.

These changes went into effect for monthly indices on trade date June 24 for July bidweek, and for daily indices on trade date June 28 for flow on July 1.

The new methodologies are as follows:

Transco, zone 5 delivered South (daily and monthly market)

Deliveries from Transcontinental Gas Pipe Line on the 30-inch, 36-inch and 42-inch lines from the Georgia-South Carolina border up to but not including Station 165 in Virginia. Transactions at Transco's Station 165 Zone 5 pooling point and deliveries from Transco north of Station 165 are not included. Transactions are also included in the Transco, zone 5 delivered index.

Transco, Station 165 (daily and monthly market)

Transactions at Transcontinental Gas Pipe Line's Station 165 Zone 5 pooling point near the Virginia-North Carolina border in Pittsylvania County, Virginia. Transactions are also included in the Transco, zone 5 delivered index.

The methodology for the Transco, zone 5 delivered and Transco, zone 5 delivered North indices did not change. Station 165 trades continue to be included in the generic Transco, zone 5 delivered daily and monthly markets.
