Measuring DNSP Outputs for Economic Benchmarking AER Economic Benchmarking Workshop #4 30 April 2013 Denis Lawrence and John Kain
www.economicinsights.com.au 2 Main Issue Data requirements Are there any variables missing from table 1 in section 3.2 that should be there? Are the definitions proposed appropriate for economic benchmarking? Should any of the definitions be altered to ensure consistency across DNSPs?
www.economicinsights.com.au 3 Other Issues Calculating output weights Including reliability measures as outputs Scope of services to include System capacity or peak demand? Which peak demand?
