The Modulation Service for the TTPC–TMPC route has recently gone live on the PRISMA platform.

Developed with the SeaCorridor Group, this new feature introduces a flexible mechanism for gas flow management, allowing shippers to temporarily retain and defer gas delivery within the pipeline’s physical limits. Available via PRISMA auctions, the service enables:

• Enhanced flexibility along the TTPC–TMPC route

• Transparent allocation through standardized processes

• Optimized timing for delivery and balancing

How to Participate in Modulation Service Auctions

As introduced during our user test in March, the new PRISMA platform design will be rolled out starting December 2025.

It features a vertical menu, clearer navigation, and an improved interface to make your daily work smoother and more accessible.

You can switch to the new design from the upper-right corner — or return to the old version anytime during the rollout.

The rollout will happen in several phases:

• Phase 1 (two weeks later): Toggle available — old design remains default.

• Phase 2 (March 2026): Toggle available — new design becomes default.

• Phase 3 (after the Yearly Auctions 2026): Toggle removed — new design permanent.

During Phases 1 and 2, you’ll have time to explore, test, and share feedback before the transition is complete.

Find more information and the full rollout timeline in the blog article linked below.

To further improve your experience on our platform, we have recently restructured our General Terms & Conditions (GTCs).
