Considering that the shortage of operational reserves was significant and in some hours exceeded 1000 MW, and further deterioration of balancing conditions could not be excluded, during operational planning procedures for December 6 PSE applied necessary remedial measures, including the use of inter-TSO emergency support power from neighboring systems: Lithuania, Sweden, Germany and Ukraine. The applied measures allowed for securing the system balance with the required levels of operational generation reserves.
We expect that on 7 December 2021 Polish operational reserves will also be tight. PSE is continuously analyzing the situation and will take all necessary measures to ensure the operational security of the Polish power system.
