This is commonly measured as the average number of minutes off supply per customer (per annum) or the average number of interruptions per customer. Figure 12 presents the average number of minutes off supply per customer, excluding the effects of major events, planned outages and transmission outages. Figure 12 Average minutes off supply per customer (2010–2014) Figure 13 presents the average number of interruptions to supply per customer, excluding the effects of major events, planned outages and transmission outages. There are other measurements of reliability but the frequency and duration of interruptions to supply per customer are the IEEE standard measures for DNSPs. Figure 13 Average number of interruptions per customer (2010–2014) Inputs The inputs used in this report are assets and opex. DNSPs use a mix of assets and opex to deliver services. Electricity transmission assets can provide useful service over several decades. However, benchmarking studies typically focus on a shorter period of time. For our MTFP analysis we use physical measures of capital inputs. Using physical values for inputs has the advantage of best reflecting the physical depreciation profile of DNSP assets. Our MTFP analysis uses five physical measures of capital inputs: the capacity of transformers, overhead lines above 33kV, overhead lines below 33kV,
