What is an NTC?
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).
These documents outline the GB methodology for commercial arrangements for payments relating to interconnector (IC) capacity restrictions resulting from NTC restrictions set by National Energy System Operator (NESO). The commercial arrangements in these documents should be applied to:
- all interconnector projects (existing and future) that are connected to the GB transmission system
- capacity calculations made both before and after the firmness deadline
This methodology should be applied in full to ensure consistency of NTC arrangements across all GB connected interconnectors.
