Platts proposes to change underlying component assessment used in Platts Conventional Energy Index

Platts, part of S&P Global Commodity Insights, is proposing to change an underlying component assessment used in the Platts Conventional Energy Index (ANVEA00), effective Sept. 1.

For the underlying components used in the calculation of the index, Platts is proposing to replace GIA North America by Flow Date (IGOAA21) with Henry Hub by Flow Date (IGBBL21). This proposed change is necessitated by the discontinuation of Platts GIA natural gas indices from Sept. 1.

For more details, please refer to the following subscriber note published June 24: Platts to discontinue Columbia Gas, Appalachia non-IPP and GIA natural gas indices.

The weightings used in the calculation of the Platts Conventional Energy Index will not be impacted by this proposed change.

The Platts Conventional Energy Index reflects the physical prices of the global primary energy mix from conventional energy sources such as oil, gas, coal and nuclear. The index weightings reflect the proportion of global energy consumption by source, excluding renewables. The weightings are reviewed annually to keep the index representative of global supply and demand trends.

More details about the calculations and methodology of the index can be found in the Platts Global Commodity Indices Specifications Guide here: commodity-indices-specifications.pdf.
