Beyond the Five Core Services

Operating an increasingly complex grid is a sensitive task in which an error can have enormous consequences for European consumers and the European economy. Regional collaboration through RSCIs represents an important shift from the national system operations. To deliver full benefits while keeping transition costs and risks at reasonable levels, RSCIs should be managed carefully. All parties involved (TSOs and their RSCIs, ENTSO-E, national regulators and market participants) need to learn how to work together under this new formula.

Once this is ensured and the five core services are available across Europe, next steps could follow. Detailed cost-benefit analysis could identify how the services that are potentially better conducted at regional level could be further developed and how an efficient, secure and cost-effective service structure between TSOs and RSCIs can be achieved. ENTSO-E and TSOs are currently working to identify which services are best delivered at regional levels rather than by each TSO individually from longer term to as close to real-time as possible. Because the final responsibility for security of supply lies within Member States and their TSOs, technical constraints due to the time necessary for TSOs to perform real-time operations based on RSCIs input and issues related to local security analysis draw a line between what can and cannot be delivered by RSCIs.

Future enhancement of the operational coordination of TSOs may see RSCIs play even stronger roles in ensuring security of supply, notably by coordinating aspects of risk preparedness plans and delivering enhanced short-and medium-term adequacy forecasts1.
