Eskom is planning up to 15 extra coal-fired power stations to cater for South Africa’s soaring electri¬city demand -- which would at least double South Africa’s contribution to global climate change. Eskom coal specia¬list Johan Dempers identified the Waterberg in Limpopo as a new expansion area. He reportedly told a coal conference in Lephalale there was potential for eight new Eskom power stations in the Waterberg coalfields over the next 20 years.
