The basic obligations of the Transmission System Operator are set out in EU legislation, in particular in the so-called grid codes. Under the domestic law, the TSO's obligations are determined in particular by the provisions of the Energy Law and the executive acts issued on its basis, which define both the tasks to be undertaken by PSE and how they are to be financed, as well as the applicable technical standards and reliability criteria.
The costs of performing our tasks are regulated costs, covered by transmission fees paid by the transmission system users according to the tariff approved by the President of the ERO. As an operator, we perform tasks using the technical resources of entities connected to the transmission system. These entities are obligated to make the resources available under applicable laws or appropriate civil law agreements.
