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

As the code administrator for the STC, we maintain the code and oversee any proposed changes to it. All changes have to be reviewed by the STC modification Panel and approved by the Panel, or by Ofgem.

You can find out more about the roles and responsibilities of everyone involved in the STC procedures document, on the Code documents page.

For more information about the code, please contact [email protected].
