Modelling the Cost of Electricity Outages in Zimbabwe

This study provides the model to be used when estimating the cost of unserved utility especially electricity. It also identified different impacts of outages for different stakeholders. A three model framework has been provided to show the demand and supply of electricity with outages. The segment demand model assesses demand for electricity given outages and backup supply from own private sources. The modeling framework for electricity outages highlights two cost of outages, the direct cost and backup cost and if summed provides total outage cost. The framework can also be used in assessing direct cost for interruption in services such as water supply and telephone services.
