Quantitative reliability evaluation is an important aspect of power system planning and operation. The indices produced in these applications are utilised in a wide range of management decisions throughout a utility. One issue, which is often debated, is the cost associated with a particular level of reliability. In order to make this argument complete, it is necessary to examine the benefit of having a particular level of reliability based on the losses incurred as a result of losing the power supply. Estimates of the impacts of interruptions in service can be obtained by assessing the losses incurred by different customer types and categories. These data can then be used to calculate cost of energy not served in the selected utility service area. This paper presents the results of an investigation of direct, short-term impacts and associated costs incurred by three categories of electrical consumers, industrial, general purpose and household consumers, resulting from interruptions to the power supply. |
