Is the new agency going to replace national regulatory authorities?
No, the work of Agency for the Cooperation of European Regulators will complement that of the existing NRAs. ACER should act as the responsible regulator, especially in situations where there is a European-wide interest. For example, where cross-border pipelines are concerned and the concerned NRAs cannot agree on a common solution, ACER will take the necessary regulatory decisions rather than the NRAs.
