In February this year balancing energy exchange and settlement tests will take place under the European Imbalance Netting (IN) imbalance compensation mechanism. If they run successfully, Polskie Sieci Elektroenergetyczne will start regular, operational activity in IN.
According to the announcement published on the PSE website, the Polish transmission system operator has already met all the formal and technical requirements set for the members of the International Grid Control Cooperation (IGCC) project, under which the IN mechanism is being implemented. PSE has also been tested in a test environment. The final step is testing on the production environment, which is scheduled for February 12-14. After their successful completion, PSE will be able to join IN operationally.
IN is a real-time process carried out by European transmission system operators and prevents the activation of secondary regulation in opposite directions and enables the settlement of imbalance costs. The IN mechanism aims to reduce the balancing costs of connected power systems.
The obligation to join PSE to the IN mechanism results from Commission Regulation (EU) 2017/2195 of 23.11.2017 establishing guidelines for balancing (Guideline on Electricity Balancing, EBGL). In accordance with art. 22 EBGL, all power transmission system operators who implement the automatic secondary frequency regulation (aFRR) must join the IN mechanism.
Currently, operators from Germany, France, Austria, Switzerland, Denmark, Belgium, the Netherlands, the Czech Republic, Croatia, Slovenia and Italy are operationally involved in the IGCC project.
