InnoGrid2020+ gets ready for the twenties


In recent years, InnoGrid2020+ has proved to be the European event on innovation in electricity networks. The widely recognised annual conference is jointly organised by the European Network of Transmission System Operators for Electricity (ENTSO-E) and the European Distribution System Operators for Smart Grids (EDSO). This year’s InnoGrid2020+, the seventh edition of the event, will be held at BOZAR, Centre for Fine Arts, in Brussels, Belgium, from 15 to 16 May. “Get ready for the twenties ‒ A vision for Europe’s power grid and beyond“ is the most promising title.

The central theme of 2018 addresses the high expectations of customers, market participants and policy makers regarding what the electricity system and network should deliver as services beyond 2020. The circle of speakers consists of high-ranking policy makers, researchers and project developers but also of grid users and citizens. Ben Voorhorst, President of ENTSO-E and Chief Operating Officer of TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), will co-host the inaugural session.

InnoGrid2020+ 2018 provides insights and solutions for the challenges of the next decade. In addition to the multifarious presentations there will also be profound project related breakout sessions on concrete issues of power networks and their essential role for the energy future. The relevant key terms here include system and cyber security, flexibility, active system management, sector coupling, and e-mobility.

New generation of synthetic cables


Large amounts of energy from renewable sources are produced in the north of Germany while the consumption centres are situated in the industrial south. To bridge the gap between the producing north and the consuming south, high performing power lines are utterly needed. Two of these envisaged extra-high voltage lines are the SuedLink-line from Schleswig-Holstein to Bavaria and Baden-Württemberg and the SuedOstLink-line from Saxony-Anhalt to Bavaria.

In late 2015, significant changes in the federal legislation regarding the German energy transition came into effect: In cases of new construction projects underground cables are to be favoured over overhead lines. This affects directly the planning for the two key projects of the energy transition, SuedLink and SuedOstLink. In order to implement the legal specifications efficiently, TSC member TenneT, the Dutch-German transmission system operator (TSO), and the further three German TSOs and TSC members, 50Hertz, Amprion und TransnetBW, have initiated long-term test series on the newest generation of extruded synthetic cables. These high-performing direct current cables are designed to withstand high transmission rates up to 525kV. Therefore they are capable of reducing the land usage and environmental impacts.

The prime subjects of the joint studies are the long-term durability and ageing behaviour of the cables. The individual tests will largely follow an internationally recognised recommendation by the Council on Large Electric Systems (CIGRE, Conseil International des Grands Réseaux Électrique). The tests will take place in independent institutes authorised by the four cooperating TSOs.
