The individual Network Development Plans (NDPs) of the European transmission system operators (TSOs) set the parameters for the development of the electrical transmission infrastructure on the national scale. At the pan-European level, the biennial Ten-Year Network Development Plans (TYNDPs) – conceived by the European Network of Transmission System Operators for Electricity (ENTSO-E) with the participation of the member TSOs – provide the framework for in-depth identification of continent-wide key investments and infrastructure projects with high potential. It is the task of the Agency for the Cooperation of Energy Regulators (ACER) to assess the coherence of national and EU-wide NDPs.
ACER now has published its detailed opinion on the schemes, scenarios and projects included in the most recent national NDPs. ACER is pleased to find that the coherence with the European TYNDP has substantially improved, e.g. through a wider use of cost-benefit analysis for projects or a more systematic use of a multi-scenario approach. In its 84-page opinion, however, the Agency also calls for some improvements to reduce inconsistencies.
