What do these prices represent?
Weekly GPI prices represent the simple average of next-day natural gas spot prices published in Daily GPI for a given week. Daily prices included in these averages represent both exchange-traded deals as well as deals reported directly to NGI. Prices are expressed in $U.S. per MMBtu with the exception of Canadian locations which are published in CDN$/Gj. To learn more about Daily GPI prices, check out our Price Index Methodology.
