ACER received the Transmission System Operators’ (TSOs’) and ENTSO-E’s proposals:

ACER’s decisions on these proposals should facilitate the integration of balancing capacity markets, create welfare and lower procurement costs of balancing capacity while ensuring security of supply.

Why we are consulting

ACER assesed the proposals received and revised them where necessary in order to ensure their contribution to market integration, non-discrimination, proper functioning of electricity markets, and their compliance with the Regulation on the internal market for electricity and the electricity balancing guideline.

Together these three proposals aim at integrating national balancing capacity markets with the use of cross-zonal capacities. The aim is to lower the costs of procuring electricity balancing capacity while ensuring security of supply. This can be archieved by reducing the overall balancing capacity needs and by lowering the procurement cost of that balancing capacity which needs to be procured.

For taking an informed decision on these proposal, considering their impact on stakeholders, ACER invited interested parties to share their views.
