Second AC interconnection between Poland and Lithuania - Harmony Link is foreseen to be installed by 2030 4th quarter. In line with the current evaluations of Litgrid and PSE, if all cross border elements are in operation and with necessary countermeasures available – the NTC values on the Polish-Lithuanian border could reach dynamic limits, i.e. up to 1200MW. The actual NTC values will depend on system operation conditions.
