Grid-connected renewables pass 7 GW mark in 2025
In December 2025, three solar projects, Grootfontein 1, 2 and 3, and the San Kraal Wind Farm came online, adding a combined 365 MW to South Africa’s national grid.
Since 2011, the government has held seven bid windows under the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP), contracting more than 12 GW of renewable capacity.
About 60% of that capacity (7 GW) has now been built and is supplying electricity. This includes all projects from the first four bid windows and seven projects from bid window five.
Wind accounts for just over half of the installed capacity at 53.7% (3.763 GW), with solar PV close behind at 45.5% (3.187 GW). Small biogas and hydro projects make up less than 1%.
The bulk of this capacity is located in the Northern Cape, which hosts 3.778 GW (54%) of projects. The Eastern Cape follows with 1.496 GW, and the Western Cape with 1.097 GW.
In addition, three solar projects procured under the Risk Mitigation IPPPP began operating in 2023, contributing a further 0.15 GW.
