NTC or Net Transfer Capacity is a value used by System Operators (SOs) in order to set the maximum capacity that an interconnector can import and/or export to that SO’s grid for a given Market Time Unit (MTU). The NTC process is a method of calculating the resulting maximum import and export capacities that an interconnector can release to the market (Final NTC).
