Change in manual capacity conversion procedure

As of 17 October 2025, Gasunie Transport Services B.V. will switch to an ex-post model for manual processing of capacity conversions. This means that requests must be submitted no later than 3 working days after the relevant auction has ended.

This change applies only to yearly, quarterly, and monthly products. For daily products, capacity conversion remains possible only via the PRISMA platform and not manually. For within-day products, capacity conversion is not possible.

Please note: this change does not apply retroactively and does not grant rights to past capacity conversions.
