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

Platts, part of S&P Global Energy, will 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.

From March 31, 2026, day-ahead pricing at Platts will reflect the delivery of natural gas on the next UK working day only. The weekend assessment will reflect natural gas delivered on all non-working days in the UK, including weekends and bank holidays. This logic will be for all natural gas hubs across Europe, as is the prevailing market practice.

As such, day-ahead +1, day-ahead +2, and day-ahead +3 price assessments will be discontinued across all of Platts European gas hubs.

In cases where bank holidays fall adjacent to Saturday and Sunday, Platts weekend price assessment will 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 will apply to Tuesday, April 6, the next UK working day. The weekend assessment will 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 will be priced as an additional weekend product. The weekend assessment published on the following working days will 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 will publish a weekend price assessment for all its hubs on Monday, Dec. 24, encompassing both days. The weekend assessment published following the holiday, beginning Thursday, Dec. 27, would encompass Saturday, Dec. 29, and Sunday, Dec. 30.

The following symbols will be discontinued as part of this decision:

The assessments affected by this change 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, will also be discontinued. Symbols that are calculated using the day-ahead + symbols will be updated to reflect this change in methodology.

Flow date symbols will now reflect weekend assessment values on bank holidays instead of the previous day-ahead/day-ahead + prices from March 31, 2026. For instance, on Jan. 1, 2027, subscribers seeking historical flow-date spot pricing for the Dutch TTF will see the weekend assessment value published on Dec. 31, rather than the day-ahead assessment.

Platts initially proposed the change via a subscriber note on Jan. 6, 2026.
