South African households, like households in many other developing countries, are faced with regular power outages. This is a big problem, since the outages that the households experience are both frequent and long in duration. Efficient electricity infrastructure investment decisions are possible only if the welfare loss of electricity blackouts is determined. We estimate a measure for welfare analysis. The surveys were conducted using electronic equipment (gadgets/tablets) instead of the orthodox paper method. We subject respondents to eight power outage scenarios.
