Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Core CCR: Cooperation of 16 European TSOs to further integrate European Energy Markets

Downloads & Contact

Sixteen TSOs follow a decision of the Agency for the Cooperation of Energy Regulators (ACER) to combine the existing regional initiatives of former Central Eastern Europe and Central Western Europe to the enlarged European Core region (Decision 06/2016 of November 17, 2016).

The countries within the Core region are located in the heart of Europe which is why the Core CCR Project has a substantial importance for the further European market integration. 

Therefore, the TSOs have confirmed their commitment to realize all CCR-related obligations according to the respective European Commission Network Codes and Guidelines on electricity. The sixteen TSOs continue the development of a common day-ahead flow-based capacity calculation methodology in the Core CCR, project already started in March 2016. In accordance, the TSOs will also design and implement common capacity calculation methodologies for intraday and long-term time-frames. These methods will enable the TSOs to optimize the transmission capacity of the grid by maintaining high level of security of supply. Also, the Core Project will develop a common methodology for coordinated redispatching and countertrading to effectively relieve congestions within the interconnected transmission network.

For an effective cooperation, the TSOs are setting up the Governance structure of the Core CCR and are working on a Roadmap to perform the related tasks. 

For reasons of transparency and information, the Core CCR TSOs plan to engage the concerned Market Parties of the Core CCR. These stakeholders are invited to get involved into the discussion and on the status of deliverables via periodic consultative groups. A first stakeholder workshop is planned to be scheduled in Q1 2017.
