The Indonesian Power Authority is planning to renovate and uprate seven hydropower stations in Java to expand plant life expectancy, ensure operating safety and reliability, and increase power and generation within economical limits. The power plants were constructed in the early 1920s and extended between 1945 and 1950. Their capacities vary between 4 and 20 MW. For the renovation project, Colenco Power Consulting Ltd (formerly Motor-Columbus Consulting Engineers Inc) is acting as a consultant to PLN. In February 1990, Colenco inspected all seven power plants. The results of the inspections served as the basis for the development of renovation plans for each of the seven hydropower plants. To determine the cost of the proposed renovation plans, appraisers had to determine a method for comparing the value of an existing plant to that of a renovated one. The two different evaluation methods used for these comparisons are the focus of this paper.
