The EU Regulation on the internal electricity market (2019/943) calls for a higher degree of coordination between transmission system operators (TSOs) at regional level. This is to be achieved through the establishment of Regional Coordination Centres (RCCs). Regulation 2019/943 provides that the future RCCs will act more autonomously in terms of risk prevention than the current Regional Security Coordinators (RSCs) like the Munich based TSCNET Services. On 6 April 2020, the Agency for the Cooperation of Energy Regulators (ACER) published a decision on the geographical scope of the RCCs (ACER Decision 10/2020) and defined the so-called System Operation Regions (SORs). The TSOs of each SOR were invited to submit a proposal on the establishment of RCCs to the relevant national regulatory authorities (NRAs).
The 19 TSOs of the Central SOR – including all TSCNET shareholders except the non-EU TSO Swissgrid from Switzerland and also three TSCNET customers – now have submitted their joint proposal for the RCC establishment in accordance with Article 35 of Regulation (EU) 2019/943. It was published by the German Federal Network Agency (“Bundesnetzagentur“). The TSOs’ suggestion is to develop existing RSCs into RCCs by adapting them to comply with the requirements of the EU Regulation. The TSOs are of the opinion that despite their increased autonomy, the future RCCs should have their grid stability measures confirmed by the TSOs. The respective TSOs concerned should be able to carry out reviews where appropriate and to oppose RCC measures on well-founded reasons. This requires an intensive exchange of information between RCCs and TSOs.
The paper proposes working agreements and service contracts as basis for the TSO-RCC cooperation. The core tasks of the RCCs should remain those of the RSCs, such as security analysis, outage planning coordination, capacity calculation, adequacy forecasts, or grid modelling. In addition, the RCCs should assist TSOs in identifying transmission system extension and modernisation priorities. RCCs should also be involved in assessing the extent to which foreign capacity may participate in national capacity mechanisms. A proposal from the European Network of Transmission System Operators (ENTSO-E), which is still pending, shall define which tasks the RCCs will perform in determining regional reserve capacity and in the regional procurement of balancing power.
