Eskom Holdings SOC Ltd., the state utility that supplies 95 percent of South Africa’s power, is overhauling the continent’s sole nuclear plant with the aim of extending its lifespan by at least 20 years.
The revamp of the 1,860-megawatt Koeberg facility comes as Eskom struggles to produce enough electricity to meet demand and is grappling to address construction glitches and cost overruns at two new coal-fired power stations. The nuclear plant is one of the cheapest to operate in the utility’s fleet.
Koeberg “has been well-maintained over its 35-year history and hence only a relatively small number of large components require replacement,” Eskom said in an emailed reply to questions. “These replacements have been timed to so they coincide with routine unit shutdowns for refueling and maintenance.”
