Berlin. The grid fees of 50Hertz are expected to rise by seven percent in 2020 compared to 2019. The main reasons for the increase are, among others, the costs for the legally required provision of reserve power (capacity reserve and safety readiness of lignite-fired power plants) as well as high investments in grid expansion. At the same time, these investments at 50Hertz also lead to significant structural savings in congestion management costs. For example, 50Hertz expects the interventions in conventional generation (redispatch) and the drop in feed-in from renewable generation plants (feed-in management) to reduce costs by an estimated €100 million, which has been taken into account in the cost-cutting calculation of grid fees for 2020. The increase in transmission grid fees has an impact of € 3 per year on a private household customer and is therefore hardly noticeable. For an industrial customer connected to the extra-high voltage grid with an annual usage of around 4,000 hours and an output of 100 megawatts, the additional charge would be approximately € 600,000 in 2020.
The fact that at 50Hertz we can again report lower costs for congestion management as things stand at present shows impressively that grid expansion is not only necessary for the secure integration of more renewable energy into the grid, but also has a cost-reducing effect on grid fees - even if we have to record a total increase for 2020. We will continue to do everything in our power to further reduce congestion management costs - through grid optimisation, reinforcement and expansion and an even closer cooperation between the four German transmission system operators.
