The new pan-European digital platform is designed to increase transparency and improve access to information about the hosting capacity of Europe’s electricity grids, including both transmission and distribution networks.
ENTSO-E, the association of European electricity transmission system operators, and the DSO Entity, the body representing European distribution system operators, have launched Capacitypedia, a new pan-European digital platform designed to increase transparency and improve access to information on European electricity grid hosting capacity across both transmission and distribution networks.
The two organizations describe the initiative as one of the most comprehensive coordination efforts between European electricity companies to date in the field of grid transparency. Capacitypedia acts as a centralized portal that collects and structures publicly available data on connection capacity, published by transmission system operators (TSOs) and distribution system operators (DSOs) across Europe. The aim is not to replace existing national platforms, but to provide a single access point that allows developers, utilities, investors and industrial users to more easily locate and compare capacity availability across different European markets.
The platform arises from Action 6 of the EU Grid Action Plan, an initiative led by the European Commission to accelerate the development and modernization of electricity networks. This action is mainly aimed at improving the visibility of available grid capacity for new sustainable energy projects, energy storage and charging infrastructure for electric vehicles.
Capacitypedia includes an interactive, color-coded pan-European map showing which countries currently provide public information on network capacity. It currently covers Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Montenegro, Netherlands, North Macedonia, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden and Switzerland.
Through dedicated country and operator pages, users can access different levels of technical detail and follow direct links to official information from the grid operators, ensuring that the data under their responsibility remains up to date. A central element of the platform is the concept of hosting capacity: the ability of the electricity infrastructure to integrate new generation, demand or storage without compromising the stability or quality of the system. Capacitypedia also aims to promote a more standardized interpretation of this concept across Europe, including aspects such as data granularity, the distinction between firm and flexible capacity, and coordination between transmission and distribution networks.
