Kariba: The hydro generation at Kariba remain constrained due to low water levels. However, there has been an improvement in the generation levels from as low as 190mw to an average 265mw by end of January. The dam is reported to have risen by nine centimetres by then due to the inflows. The receives average yearly inflows of are around 40 billion cubic metres, however, the dam only received18,84 billion cubic metres of water during 2019.
Hwange: In January, there were some flooding which affected generation as the coal got wet and as a result generation stopped. This was rectified and generation was restored.
There are other two units that are not generating where repairs and maintenance are being carried out. The first of these units is expected back into generation by end of March. This will increase supply, provided that the other units remain in production. However, generally, it is difficult to guarantee consistent generation due to the age of the machinery; spares availability and technical expertise.
Small Thermals: Munyati, Harare and Bulawayo are not producing anything.
Imports: ZESA still have existing arrangement of 400mw supply from South Africa. Of the 400mw, 100mw is firm, while the balance (300mw) is non-firm. The 300mw is normally accessed off peak and South Africa’s peak is at the same time as Zimbabwe’s peak.
