Pumping up Lesotho’s economy

The current peak demand of electricity in Lesotho is approximately 140 MW, 75 MW of which can be supplied by the existing Muela plant, implemented as part of the first phase of the Lesotho Highlands Water Project for transfer of water to South Africa; Muela is the only generation facility in the country apart from some mini hydro plants. The remaining 65 MW is imported from South Africa and Mozambique, but dependence on energy imports from neighbouring countries, particularly expensive peak power, is not a sustainable option for Lesotho, particularly in view of the future increase in demand. Access to inexpensive energy is also vital for Lesotho to fulfil its planned rural electrification programme, and to enhance socio-economic development and energy security. Plans for a new major 1200 MW pumped-storage scheme are described here.
