Electric power quality disturbances can have significant economic consequences for many different types of facilities. A wide variety of solution technologies exist for mitigating the consequences of such disturbances, and a methodology for performing a comparative economic analysis is featured in this article. Different technologies are evaluated by estimating the improved performance that can be expected after the technology has been applied. The power quality cost savings are calculated for each technology along with the costs of applying the technology. The net benefits, expressed in terms of annual costs, are shown as a means of comparing the various technologies.
