Core Flow-Based Market Coupling Project Go Live set for 08 June 2022

Published:

21 04 2022


As communicated earlier, the planned go-live of 20 April 2022 for Core Flow Based
Day Ahead Market Coupling was not supported by some Core TSOs and NEMOs.
During the past two weeks, the Core project parties have intensively worked on
solutions to resolve the remaining concerns raised by some parties with regards to
certain aspects of the Flow Based Day Ahead Capacity Calculation. As a result, Core
project parties are able to announce the new go-live date: 08 June 2022 (Trading Day
for delivery on 09 June 2022).
The next steps to adequately address the concerns raised earlier are:
• The mitigations to further improve operational stability of TSO’s capacity
calculation were already implemented. In this period some issues occurred with
fallbacks for which fixes will be in place before go-live.
• To further optimise the intraday ATC capacities algorithmic improvements and
local validation processes will be implemented before go-live. Further
improvements are foreseen to be implemented after go-live.
• Dedicated reporting to NRAs will be created for all cases with RAM<20% to closely
monitor the occurrences and mitigations - this information of RAM<20% is already
publicly available in the publication tool.
• Improvements in the publication tool were implemented 1
With these measures, all project parties feel confident about going live, also
considering the current market circumstances. Moreover, all parties see a significant
benefit in the experience to gain during the summer period, prior to entering fall/winter.

CORE-FB
Communication channels
Market participants who would like to follow closer the project development are invited
to join the Core Consultative Group (CCG) by sending an email to
CoreCG@magnus.nl. The participants of the Core Consultative Group will receive
regular information, and invitations to teleconferences and meetings.
Next to the CCG a Question & Answer Forum for the Core FB MC project is currently
in use.

The Forum is available under the Core FB MC section on the JAO website, ie.
www.jao.eu.

Project parties invite all market participants to use this Forum for their
queries.
About the Day-Ahead Flow-Based Market Coupling project in the Core

CCR
The Core Flow-Based Market Coupling (Core FB MC) project promotes the
development and implementation of a flow-based day-ahead market coupling across
the whole Core capacity calculation region (Core CCR) in the framework of the Single
Day-Ahead Coupling (SDAC). The Core CCR consists of the bidding zone borders
between the following EU Member States’ bidding zones: Austria, Belgium, Croatia,
the Czech Republic, France, Germany, Hungary, Luxemburg, the Netherlands,
Poland, Romania, Slovakia and Slovenia.
Market integration - core to energy transition
The energy transition towards a carbon free electricity supply is a European challenge
that requires the use of the European electricity system to the full extent. Weatherdependent
supply and increasing demand response will lead to a different and more
intense use of the grid. The Core market integration project is aiming to create
operational preconditions to optimise the use of the system from a regional perspective
and make the single European market a reality.
