System Operator Transmission Owner Code

The System Operator Transmission Owner Code (STC) defines the relationship between the transmission system owners and the system operator.

The STC Modification Panel, under normal circumstances, meets on a monthly basis. It will convene ad-hoc meetings when required.

The Panel comprises members from the GB System Operator (GBSO), Onshore Transmission Owners (TOs) and Offshore Transmission Owners (OFTOs) and its main purpose is to evaluate and administrate modifications to the STC and review any potential consequence of such changes.
