Security and Quality of Supply Standard (SQSS)

The Security and Quality of Supply Standard sets out the criteria and methodology for planning and operating the National Electricity Transmission System (NETS).

As the code administrator for the SQSS, we maintain the code and oversee any proposed changes to them, along with other transmission licensees.. All changes have to be reviewed by the SQSS review panel or by Ofgem.

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