Successful go-live of Core Advanced Hybrid Coupling

Published:

The Core project parties are pleased to confirm the successful go-live of Advanced Hybrid Coupling for delivery day 11th of June 2026. The Core project parties would like to congratulate everyone who contributed to the successful go-live of this project.

Points to note about publication of data on the JAO Publication Tool:

  • The RAM at market clearing point (‘RAM@MCP’-column in ‘Active FB constraints’-page) is not correct, as the long-term nominations (LTNs) on the Romanian - Bulgarian bidding zone border are not fully accounted for;
  • The Scheduled Exchanges are not published for AHC bidding zone borders;
  • The ATCs on Core external borders for non-Core bidding zone borders

Fixes for these issues will be delivered in the coming days.

Improving market functioning and operational security

Advanced Hybrid Coupling enables the single day-ahead market coupling to allocate Core capacities between Core and non-Core exchanges on EU borders in the most efficient manner. Forecasted exchanges on non-Core borders within SDAC are no longer static, allowing for competition between Core and non-Core exchanges for the Core flow-based domain capacity, and reducing the risk for operational security violations due to wrong forecasts.

Communication channels

Market participants who would like to follow the Core project developments are invited to join the Core Consultative Group (CCG) by signing up to the Core CG distribution list [link]. The participants of the Core Consultative Group will receive regular information, and invitations to teleconferences and meetings. Next to the Core CG, a Question & Answer Forum for the Core FB capacity calculation project is currently in use. The Forum can be accessed via https://coreforum.my-ems.net/.

The Core TSOs invite all market participants to use this Forum for their queries.

Market integration - Core to energy transition

The energy transition towards a carbon-free electricity supply is a European challenge that requires the efficient use of the interconnected European power system. Increasing shares of weather-dependent generation and greater demand-side flexibility are changing power flow patterns and intensifying the utilisation of the grid. The Core market integration project aims to establish the operational conditions necessary to optimise system use from a regional perspective, strengthening the integration and efficiency of the single European electricity market.
