Annual Capacity Release Gas Year 2026

29.06.2026News

INT has now published the latest version of its Charging Statement, which includes the Annual Tariff Publication for Gas Year 2026.

INT is pleased to confirm;

  • No change to its base tariffs compared to GY 2025.
  • A reduction in the incentivised tariff for multiple Winters to align with the corresponding Summer product.
  • A further reduction to the UK to BE commodity charge.

Additionally, the following changes have been introduced:

  • Seasonal and 3-8+ Gas Year Bi-directional incentives have been updated to show a single tariff for both flow directions, amending the discount from 67% to 50%
  • INT will make 25% of its Firm Capacity available via IAM for within-month products, a reduction from current levels. This approach is designed to promote the use of the bundled capacity auctions held on PRISMA in order to simplify the booking process for Shippers.
