According to Mining News Pro - The 1,600-megawatt power plant will be closed for up to three months after a “review by a professional body,” Eskom said in a statement.

“The contractor concluded that the current dam has reached its maximum height and therefore it poses a safety risk to all personnel on site, including neighboring communities and could also be a cause for environmental contravention,” the utility said.

The closure adds to the environmental challenges faced by the company, which produces almost all of South Africa’s power. Eskom also faces the potential partial closure of its Kendal power plant because it breaches pollution emission limits.
