The energy transition entails many changes for the energy industry, such as the increasing generation of decentralised and volatile renewables, new actors on the market like aggregators, or the active role of customers ‒ all these developments require flexibility and pose a challenge for every player in the energy market, but above all for those responsible for a stable grid and a secure electricity supply: transmission system operators (TSOs) and distribution system operators (DSOs) sharing similar obligations and interests.
To cope with the demanding future tasks, network operators need a common vision of active system management to increase the flexibility of transmission and distribution and to coordinate them closely. This is why ENTSO-E entered into an intensive cooperation with four associations representing European DSOs a few years ago, namely the European Distribution System Operators (EDSO) for Smart Grids, CEDEC, Eurelectric, and GEODE. A significant first step was the publication of a report on TSO-DSO data management on 19 September 2016.
By signing an updated Memorandum of Understanding on 23 October 2018, the partners expressed their commitment to maintain and enhance their collaboration. The focus is on measures to realise synergies in research, development and innovation, e.g. the exchange of data and information, the introduction of new communication devices and software, and the coordinated renewal of ageing grids. In addition, the TSOs and DSOs are also working together to implement network codes more efficiently. Further fields of cooperative activities will be defined at the beginning of 2019, taking into account the European Commission’s final Clean Energy Package.
