CUSTOMER DAMAGE EVALUATION AND NETWORK AUTOMATION STRATEGIES FOR DIFFERENT URBAN ZONES Paper 0858 SIIRTO, HYVÄRINEN, HAKALA, JÄÄSKELÄINEN, LEHTONEN Osmo Siirto – Finland – Session 5 – Paper 0858
CUSTOMER DAMAGE EVALUATION AND NETWORK AUTOMATION STRATEGIES FOR DIFFERENT URBAN ZONES Paper 0858 • This presentation describes the evaluation of customer interruption costs and network automation strategies on different urban zones Osmo Siirto – Finland – Session 5 – Paper 0858
Implementation of networkautomation • Helen Electricity Network Ltd. started the network automation undertaking in year 2008, so far we have implemented network automation to one hundred secondary substations out of 2400 • The network automation investments should be targeted so, that • the cost/benefit ratio is optimum and the decrease in customer interruption cost is most significant • the new Finnish reliability criteria and possible regulatory actions should be taken into consideration Osmo Siirto – Finland – Session 5 – Paper 0858

CIC as a function of energy density and urban zone(Finnish EMA commercial group CIC value replaced by Helsinki 2010 CIC values) Osmo Siirto – Finland – Session 5 – Paper 0858
The customer damage evaluation by urban zones • The CIC on an urban core area are about three times higher than costs experienced on other urban areas. The reason for this is the combination of • commercial and public services are dominant on urban core • the CIC values of the commercial customers on the urban core are about doubled compared to other urban areas Osmo Siirto – Finland – Session 5 – Paper 0858
New reliability criteria of Finnish Energy Industries • These target levels should be achieved by the year 2030. Osmo Siirto – Finland – Session 5 – Paper 0858
Comparison and conclusions • The new Finnish reliability target levels are consistent with the results of the customer interruption costs in different urban areas. • The allowed total interruption time per a customer in a year in the city centre is one third of the time in other urban areas and the customer interruption costs in the urban core are about three times those on other urban areas • Conclusions => Next slide Osmo Siirto – Finland – Session 5 – Paper 0858
