One of the Transmission System Operator's key tasks is to determine the Net Transfer Capacity (NTC) in the interconnected grid; this allows market players to carry out their energy trading without jeopardising the interconnected grid.
The NTC is the maximum exchange programme between two areas which is consistent with the security standards of both areas.
Along with the neighbouring TSOs, Swissgrid determines the NTC values on all four Swiss borders on an annual, monthly and daily (D-2) basis.
