The draft IRP further said the decommissioning of Eskom plants would result in less than 30percent of energy supplied from coal by 2040 and less than 20percent by 2050.
The power utility's current installed generation capacity is 48000MW.
Minister of Energy Jeff Radebe said the concerns raised about the constraining of renewables had been addressed and the annual build limits on renewables were removed.
“The electricity generation and distribution landscape in South Africa is changing at a rapid pace, compared to the period before 2010. In keeping to our climate change commitments, the country has also introduced renewable energy through independent power producers,” Radebe said. “Electricity demand is therefore no longer captive to the national grid (Eskom or municipalities), which impacts supply and demand planning.”
