What are Cross-Border Interconnectors
To turn national electricity grids into a large European electricity market, the various national transmission system operators (TSOs) need transit capacity for cross-border electricity trade. These border connection points, also called cross-border interconnectors, enable TSOs at international level to transfer electricity from one national grid to another. Only cross-border interconnectors can turn on-balance-sheet electricity trading into real, physical electricity deliveries. Their expansion is therefore a central starting point of the European Commission's electricity market policy and the implementation of the integrated European energy market.
