Eskom Holdings is battling to keep all the units of its biggest operational power plant open after being served with a compliance notice by South Africa’s environment ministry because of its high levels of air pollution. The indebted power utility has failed to fully repair pollution-abatement equipment at its 4 116 MW Kendal power plant that began malfunctioning in early 2018 and was damaged further in a strike later that year. The ministry issued the notice in December saying the plant would need to close two of its six generating units, 1 and 5, if action wasn’t taken to bring them back into compliance. It demanded maintenance plans for the rest.
