Platts discontinues Columbia Gas, Appalachia non-IPP and GIA natural gas indices

Platts, part of S&P Global Commodity Insights, has discontinued the Columbia Gas, Appalachia non-IPP monthly (IGBJU03) and daily (IGBJU00) natural gas indices. The final publication of the Columbia Gas, Appalachia non-IPP monthly index was the September 2025 edition of the Inside FERC Gas Market Report First of Month, while the daily's final publication was on Aug. 28.

This was due to a lack of market liquidity and follows a proposal published May 19.

Platts also discontinued the Gas Indices Americas daily Northeast (IGKAA00), South (IGLAA00), Midwest (IGMAA00), West (IGNAA00), and North America (IGOAA00) indices, with the final publication date occurring Aug. 28. As a result, the GIA commentary will no longer be published.
