These documents outline the GB methodology for commercial arrangements for payments relating to interconnector (IC) capacity restrictions resulting from NTC restrictions set by National Grid Electricity System Operator (NGESO). 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.
