TransnetBW, one of the four German transmission system operators (TSOs), presented its study “Electricity Grid 2050” (“Stromnetz 2050”) in a Twitter online event on 22 April. The study, in which the TSCNET shareholder drafts a scenario for a largely climate-neutral energy system in Germany and Europe, is now available to anyone interested. The TSO outlines a target vision of the German energy system after the climate protection and energy transition goals have been achieved and indicates, which requirements must be met at system and grid level in a sustainable energy future.
The live-stream presentation of the study, followed by an online question and answer session, was hosted by Michael Jesberger, member of the TransnetBW executive board, together with Christian Schorn, Head of Asset Management & Operations at TransnetBW, Dr. Felix Matthes, research coordinator for energy and climate policy at the Öko-Institut (Institute for Applied Ecology, a non-profit, private-sector environmental research institute) and Helmfried Meinel, Ministerial Director of the Baden-Württemberg Ministry of the Environment, Climate Protection and the Energy Sector.
“The energy transition is progressing, and climate policy goals have been set: By 2050, the energy system in Germany should be largely climate-neutral. The transmission grid plays a decisive role in this,” explained Michael Jesberger. “With the study ‘Electricity Grid 2050’, we are revealing how a greenhouse gas-neutral energy system can look like.” By considering the time after the climate targets are reached, the study extends the time frame beyond the requirements of national planning guidelines. “With this approach of thinking the energy transition from the end, the study provides a new basis for discussion of the methodological refinement of the German Network Development Plan (NEP), which so far only plans the transmission grids ten to 15 years in advance,” stated Christian Schorn.
According to the study, it is necessary to increase the installed capacity of wind energy and photovoltaic systems by three to four times compared to 2018 to achieve the energy and climate policy goals by 2050. In addition, the heating and transport sector will have to be largely electrified, which will lead to an increase in net electricity demand of over 50%. This will only be partially compensated by the integration of the European internal electricity market and the increasing cross-border electricity trade. Hence, the transmission grid planned in the NEP is not sufficient to achieve the energy goals. The integration of renewable energies requires a set of grid extension measures that goes far beyond the previous plans. The study “Electricity Grid 2050” offers a new level of detail of the future grid and is intended to stimulate a fruitful debate.
