Platts proposes to realign European natural gas day-ahead, weekend price assessments

Platts, part of S&P Global Energy, is proposing to realign its European natural gas day-ahead and weekend price assessments to reflect the prevailing market practice, effective March 31, 2026.

Currently, Platts reflects longer holiday weekend pricing at European natural gas hubs by extending the day-ahead assessment with day-ahead +1, day-ahead +2 and so on, depending on the length of the public holiday.

Going forward, Platts is proposing that all day-ahead pricing reflects delivery of natural gas on the next UK working day only. The weekend assessment would now reflect natural gas delivered on all non-working days in the UK, including weekends and bank holidays. This logic would be for all natural gas hubs across Europe, as is the prevailing market practice.

This proposed change would require day-ahead +1, day-ahead +2, and day-ahead +3 price assessments to be discontinued across all of Platts European gas hubs.

In cases where bank holidays fall adjacent to Saturday and Sunday, Platts weekend price assessment would integrate both the bank holiday and weekend days.

For instance, on Thursday, April 2, 2026, prior to Good Friday, the day-ahead price published by Platts would apply to Tuesday, April 6, the next UK working day. The weekend assessment would include Good Friday (April 3), Saturday (April 4), Sunday (April 5), and Easter Monday (April 6).

In years where Christmas and Boxing Day or New Year's Day occur mid-week, these would be priced as an additional weekend product. The weekend assessment published on the following working days would refer to the Saturday and Sunday of that week.

For example, if Christmas Day falls on Tuesday, Dec. 25, and Boxing Day on Wednesday, Dec. 26, Platts would publish a weekend price assessment for all its hubs on Monday, Dec. 24, encompassing both days. The weekend assessment published starting Thursday, Dec. 27, would be for Saturday, Dec. 29, and Sunday, Dec. 30.

The following symbols would be discontinued as part of this proposal:

The assessments affected by this proposal are currently published in European Gas Daily and European Power Daily. They also appear on the following fixed pages; PEP0641, PEP0646, PEP0648, PEP0652, PEP0668, PEP0675, PEP0676, PEP0685, PGN0685, PEP0686, PGN0686, PEP0691, PEP0692, PEP0802, PGN0802, PEP0820, PEP0822, PEP0823, PEP0873, PEP0874, PEP0875, PGN0056, PGN0806, PGN0824, PGN0825, PGN0826, PGN0834, PGN0835, PGN0840, PGN0850, PGN0855, PGN0856, and PGN1094.

The conversion of these symbols into EUR/GJ, USD/MMBtu, and Pence/therm, as well as monthly averages, would also be discontinued under this proposal. Symbols that are calculated using the day-ahead + symbols would be updated to reflect this change in methodology.

Flow date symbols would now reflect weekend assessment values on bank holidays instead of the previous day-ahead/day-ahead + prices. For instance, on Jan. 1, 2027, subscribers seeking historical flow-date spot pricing for the Dutch TTF would see the weekend assessment value published on Dec. 31, rather than the day-ahead assessment.

Additionally, affected spark spread symbols would also utilize Weekend assessment values as input data on bank holidays instead of day-ahead/day-ahead + symbols.
