Why do we shed during the times when we need electricity most not at other times of the day?

Currently we do not have sufficient generation resources within Zimbabwe to meet the demand for power. Our peak demand occurs from 8-11am and between 6-9pm. During these times we have to import power or run on generators that are ordinarily more expensive to run to meet our customers’ demands for power at these peak periods. Due to shortages of foreign exchange to pay for imported power we have had to limit imports. Internal generation sources are not always running due to problems stemming from the shortage of foreign exchange and cost. We do not have a problem with demand of other times of the day hence there is no need for load shedding at those times.
