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].
Our modification tracker gives you the very latest detail on current modifications for each of the four codes. It includes the purpose of the modification and the stakeholders it affects, as well as panel comments on prioritisation and where it is in the review process.
Standing groups give interested industry people the opportunity to discuss issues relating to electricity codes in more detail. Issues could relate to one or more of the codes, including the SQSS.
