CUSTOMER DAMAGE EVALUATION AND NETWORK AUTOMATION STRATEGIES FOR DIFFERENT URBAN ZONES Paper 0858
Frankfurt (Germany), 6-9 June 2011
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

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

New reliability criteria of Finnish Energy Industries
Area Total interruption time / a, customer
Number of short interruptions / a, customer
City ≤ 1 h None
Urban areas, population centres
≤ 3 h ≤ 10
Rural ≤ 6 h ≤ 60
These target levels should be achieved by the year 2030.

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
