Eskom anticipates high risk of load-shedding in South Africa for 2023-2024

Eskom, South Africa's power utility, predicts a significant risk of load-shedding exceeding 2,000MW shortfall between December 2023 and December 2024. The Generation Adequacy Report outlines both planned and likely risk scenarios, projecting persistent challenges in meeting demand and reserves. Recent intensified load-shedding, reaching Stage 6, has raised concerns, with Eskom attributing the crisis to emergency reserve depletion and external factors like a heatwave. Critics argue Eskom's explanations are insufficient, heightening apprehensions about the country's energy stability..Sign up for your early morning brew of the BizNews Insider to keep you up to speed with the content that matters.

Load-shedding increased to Stage 4 on 22 November..The power utility then announced the implementation of Stage 6 load-shedding on Friday, 24 November 2023, with the high level expected to persist until Monday, 27 November..The utility blamed the increased load-shedding on the loss of five generating units over the past 24 hours and the need to replenish emergency reserves..Ramokgopa held a media briefing to explain the intensified load-shedding and stated that generation unit breakdowns weren't primarily to blame..Instead, he said Eskom had been over-committing its emergency reserves to mitigate even higher stages..The increase to Stage 6 came as Eskom had to cut back on its pumped storage and open-cycle gas turbine usage to replenish emergency reserves."On the back of that cluster of units that had gone out, what it meant is that we had to significantly engage our emergency reserves," he said."For purposes of protecting the grid, we need to ensure that we continue to protect the reserves, so we are not going to engage them at a heightened intensity, and as a result, we don't have the benefit of the 4,600MW that we would automatically draw from our emergency reserves."Eskom Group executive for generation Bheki Nxumalo added that the heatwave experienced in the country at the time had increased demand by about 1,500MW, likely due to increased air conditioner usage.Energy analyst Chris Yelland also explained that power stations like Matimba, Majuba, Medupi and Kusile rely on dry cooling systems. These power stations are susceptible to variations in temperatures.In high temperatures, these power stations cannot cool properly and run the risk of overheating. Therefore, their output or power produced is sub-optimal.However, engineer and energy expert Mthunzi Luthuli said Eskom's excuses are unacceptable and do not justify implementing stage 6 load-shedding."This is not acceptable, blaming the weather we've always had historically. We've always had warm summers and cold winters," he said."When it's cold in winter, they tell us it's cold, and that's why we have load-shedding. When it's hot in summer, they tell us it's hot, and that's why we have load-shedding. It's nonsense."Read also:UNDICTATED: Why steelmaker AMSA forced into 35% downsizing.
