Quality of Supply Performance benchmarking: Improvements to methodologyy

The current OFGEM performance comparison and benchmark approach has, together with the IIS, delivered tangible improvements to the Quality of Supply experienced by customers. This approach was developed through collaboration between OFGEM and Distribution Network Operators (DNOs) and has stood the test of time. However, through analysis it has been shown that the approach contains a conceptual flaw, which can be corrected relatively simply. This can only add value to the process and bring further confidence to the output of the benchmarking process.
