The customers survey technique for outage cost estimation has been widely used by electric utilities in the developed countries. Customers surveys conducted in developing countries are rarely reported. Very few outage cost customers surveys conducted in developing countries are reported in the literature for residential, industrial and commercial customer categories. However, this is the first attempt to evaluate customers' electricity supply outage cost for offices belonging to both government and non-government organizations, academic and financial institutions, scientific and technical organizations in a developing country. The customer survey methodology and its findings are presented in the paper. The sector customer damage function (SCDF) is obtained for the surveyed customer category. © 2010 IEEE.

Estimating electricity supply outage cost for residential and commercial customers

The investment in a power system to satisfy the energy needs of its customers must be justified by the reliability worth to the customers. It is therefore very important to obtain a good estimate of the cost of unserved energy in order to determine the appropriate level of investment in the system facilities during system planning. This paper presents the results of a recent customer survey conducted in a developing country to estimate the costs associated with various types of power outages. The results are then used to estimate the cost of energy not served considering different types of customers. The customer's survey for residential, industrial and commercial customer categories in Nepal were carried out in 2008-2010 respectively. Three years of outage data were obtained for two selected feeders in urban, semi-urban and semi-rural areas of Kathmandu valley. The results obtained for the different areas considering the different customer mix are presented in the paper. © The Society for Reliability Engineering, Quality and Operations Management (SREQOM), India and The Division of Operation and Maintenance, Lulea University of Technology, Sweden 2010.

Estimation of cost of unserved energy: A customer survey approach

Generally developing countries are facing shortfall of power supply to meet their increasing demand. This is because of lack of coordination among various aspects of electric utilitiesgeneration, transmission and distribution. Absence of data that will show the financial and economical impact of power supply outages to different customer categories is another reason for less attention paid to improve supply reliability by the utilities in most of the developing countries. After the quantification of cost incurred by industrial customers because of non supply of electricity, the planners and policy makers will be forced to seriously think about the ways of minimizing these outages so that there are fewer outages and less adverse impact on the customers. This paper describe about an industrial customer survey carried out in Nepal to determine their outage cost. Results of the survey can be used as reference values in other developing countries with similar socio-economic profile.

Utilities in most of the developing countries do not possess relevant information to evaluate the electricity supply outage cost incurred by the customers. This paper shows the significance of customer survey techniques to evaluate customer outage cost in developing countries in the era of restructuring and globalization. Residential customer surveys that are extensively used by utilities in the developed countries can not be directly adopted in developing countries. Relevant modifications that incorporate customer behaviour in the rapidly changing socioeconomic characteristics in those nations must be adequately addressed. The results obtained using customer survey techniques are consistent with the figures anticipated and also indicate toward the need to carry out such surveys for other customer categories as well. The survey questionnaire is designed to obtain customer information to have uninterrupted power supply based on their willingness to pay (WTP), alternative actions and willingness to accept (WTA) monetary compensation for agreeing frequent supply interruptions. The outage cost evaluation is carried out using least square error method by a computer program developed in MATLAB platform. ©2008 IEEE.
