Litgrid, the electricity transmission system operator, is responsible for ensuring the long-term security of the country’s power system, which requires regular assessments of the system’s adequacy, i.e., the system’s ability to maintain a balance between electricity generation and consumption, and to ensure the security of electricity supply at all times, under both normal and emergency conditions. Resource adequacy assessments are conducted annually at the European level as part of the European Resource Adequacy Assessment (ERAA) prepared by ENTSO-E.
