Study on German-Polish TSO cooperation

16.01.2020

The two transmission system operators (TSOs) and TSCNET shareholders 50Hertz from Germany and PSE from Poland jointly conducted the “German-Polish Study on cooperation between TSOs PSE and 50Hertz in long-term and mid-term perspectives”, which now has been finalised. The study was supported by the respective national Ministries responsible for energy.

As its title suggests, the study is divided into an investigation of medium-term and long-term cooperation objectives. The mid-term part aims at improving the coordination of the operational planning processes. The following issues, among others, have been identified as important: improving the quality of forecasting of power flows at the German-Polish border and the coordinated use of cross-border remedial measures such as phase-shifting transformers as well as bilateral and multilateral redispatch. To better predict cross-border flows, PSE and 50 Hertz agreed to support the development of a flow-based methodology, and as far as the remedial measures are concerned, advanced software solutions are required. However, not only the development of an IT tool is needed here, but also advanced coordination and cost sharing in a region-wide mechanism.

For the long-term study, a modelling process carried out by the National Centre for Nuclear Research in Warsaw was used, which was consulted and monitored by experts from both TSOs. Using alternative scenarios, different time frames and market simulations, the main trends in German-Polish electricity exchange as well as future challenges for regional markets and networks were identified, such as interconnector capacities, growth of energy demands or deviating energy prices.
