Today’s energy market, with its ever-increasing share of volatile quantities of electricity from renewable sources, demands optimum capacity utilisation and systematic use of flexibility – already now and even more so in the future. To be well prepared for the challenges ahead, more than 70 partners from all over eastern Germany are working on the WindNODE project, including TSCNET shareholder 50Hertz, the German transmission system operator (TSO) responsible for the region. A core component of WindNODE is the flexibility platform, through which regional producers, consumers, and storage operators offer TSOs and distribution system operators (DSOs) flexible use of their facilities. This is intended to reduce the throttling of wind turbines in the event of grid bottlenecks.
The WindNODE flexibility platform has been in trial operation since November 2018. On 14 March 2019, capacities were offered and called up for the first time. “This means that the trial operation is now entering the practical phase and we can demonstrate that the integration of numerous producers, storage facilities and consumers in one market environment leads to less throttling of renewables – especially now in a very windy season,” explains Georg Meyer-Braune, project manager WindNODE at 50Hertz. The test phase of the platform will last until summer 2019 and processes will be gradually established at further partners, who will thus become potential suppliers. The platform will then be in continuous operation until the end of the project term in 2020. The aim is to use the dedicated facilities for congestion management also after the completion of the WindNODE project.
