NGI Will Modify Natural Gas Price Indexes Next Week
Energy operators should prepare for updates to NGI data services affecting daily and weekly gas pricing benchmarks.
Updated on Oct. 8, 2026 in Oil and Gas
Natural Gas Intelligence will implement modifications to its North American spot market price indexes starting October 13, 2026. These changes include the addition of two new indexes and the discontinuation of three existing ones.
Why it matters
Operators rely on these benchmarks for procurement and supply contracts, meaning adjustments to index definitions or availability will change how market participants measure and price their natural gas exposure.
Natural Gas Intelligence is adding two indexes while discontinuing three and amending the definitions for six others across its data services. These changes represent a broad recalibration of price reporting across the North American market.
The players
Natural Gas Intelligence
An industry publisher providing pricing data and market intelligence to the North American energy sector.
The details
The revisions affect several NGI data services, including the MidDay Price Alert, Daily Gas Price Index, Weekly Gas Price Index, Bidweek Alert, and Bidweek Survey. NGI intends for these modifications to better reflect current North American market conditions. Because NGI is suspending the publication of its Daily Gas Price Index on October 12, firms should anticipate a brief gap in reporting before the new index structure takes effect.
Timeline
August 14, 2026: NGI initially proposed these index modifications.
October 12, 2026: The NGI Daily Gas Price Index will not be published.
October 13, 2026: Daily index changes take effect.
October 19, 2026: Weekly index changes take effect.
Market Landscape
Price index modifications follow the pattern of regular reporting updates common to the energy sector. These adjustments sit in the context of broader FERC-regulated natural gas policy standards that require published indexes to accurately reflect market conditions.
Business owners should review their supply contracts to determine if they rely on the discontinued indexes and prepare for potential pricing discrepancies. Ensure your procurement and accounting teams update internal data systems to account for the amended definitions by the mid-October deadlines.
The takeaway
Reliable market data is essential for managing energy input costs, and periodic reporting shifts can disrupt long-term supply agreements. Operators should verify whether their current index-based pricing formulas are affected by these upcoming technical changes to avoid valuation errors.
What happens next
Market participants should monitor their data feeds for the Daily Gas Price Index discontinuation on October 12, 2026, and the subsequent implementation of new daily and weekly indexes on October 13 and October 19, 2026, respectively.
