A Study on Comparison of Investment Value Assessment Methods for Prioritizing Investment in Power Equipment

For utility companies that own power grids, it is crucial not only to generate revenue through power supply services but also to efficiently manage their power facility assets to reduce unnecessary expenditures. In particular, if unforeseen accidents occur due to the deterioration or failure of power facilities, it is important for utility companies to prevent critical risks such as incurring costs for damage compensation and a decline in social image, in line with their obligation to provide a stable power supply. To this end, it is essential for utility companies to develop strategies for the replacement of power facilities in addition to continuous maintenance. In this paper, NPV(Net Present Value) and BCR(Benefit-Cost Ratio) methods to prioritizing investment in power facilities are compared and analyzed in terms of cables, transformers, and lightning arresters.
