State power utility Eskom Holdings said pollution from its coal-fired plants that supply more than 80% of the country’s power kills about 330 people a year. The figure, which Eskom drew from its own research, contrasts with a number of independent reports that put the figure at between 650 and 2 000 people a year. Environmentalists are protesting over plans by Eskom and the government to possibly slow down the pace of planned closures to alleviate power outages that are crippling the economy.
