The main benefits of the interconnec tion lineThe main benefits of the interc onnec tion line

The new interconnec tion line:

enhances the reliab ility of Kosovo and Albanian systems and improves to grea ter

extend the reliab ility of the Reg ional interconnec ted system( neighb oringc ountries) rep resenting a nec essary reinforcem ent of the reg ional networks;

rea lize important cost saving in operation through joint and c oordinating operationsof both power systems;

allow to rea lize an short-term and med ium term generation d ispatch op timizationof the hyd rolog ic and thermal resources of Albania and Kosovo;

guarantee up to year 2020 the reliable operation o f the interc onnec tedTransmission Systems and ensure an adeq uate transfer c apability to a llow for theec onomic Exchange of elec tric ity be tween Kosovo and Alba nia;

mitigate some congestion prob lems on reg ional interconnec ted transmissionsystem rela ted with the Critica l North South c orridor through a dec reasing themaximum power and annual energy transits;
