Load Shedding FAQs

 Electrical feeders that feed essential services are exempt from load shedding. These include feeders to hospitals, major clinics, water and sewage pump stations, airports, broadcasting stations and major telephone exchanges. Some residential customers that share feeders with these essential loads are also inevitably exempted from load shedding.
 The load shedding programme is based on planned power shortfalls which are known before hand. However, faults may occur on internal generation systems or on interconnections resulting in the need to shed more load in order to avoid grid collapse. Such action has to be taken immediately and loading will be done outside the programme without notice.
 We are using our Ripple Control network to switch off our customer’s hot water heaters during peak periods, as a first priority. This affects all customers with a ripple relay installed in their geyser circuit. Even customers fed from circuits that feed essential services are affected.
 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.
 In a domestic household the geyser normally contributes about 60-70% of the total bill. The stove and heating requirements in winter normally contribute another 15-20%. The balance is used for lighting, pumping and other uses. Even if ZESA switches the geyser off, it will make up the time it lost by heating the water up to a present temperature at another time of the day. Hence the energy is still consumed but at a different time of the day. Cooking a little earlier or a little later, whilst inconvenient, still consumes the same power. So despite not having power when we want it, energy is still consumed, as refrigerators and deep freezers catch up on chilling their contents, geysers warm the water to the preset temperature and water pumps top up emptied reservoirs.  The electricity meter only measures the power that passed through it and since the power is still used but at a different time, the monthly bill does not change much.
 Most domestic appliances like geysers, refrigerators and deep freezers have their own duty cycle, that is to say they switch themselves in and out to regulate temperature. The additional switching imposed by ZESA will not affect the equipment.  Computers and some other electronic equipment are prone to loss of data if powered down during operation and should ideally be put on an Uninterruptable Power Supply (UPS).
