Power Plants in South Africa
South Africa has 172 power plants mapped on the OverWatts open energy atlas — the 24th-largest fleet of the 155 countries that hold any, and 0.6% of the world's mapped total. Of these, 66 operating and 99 under construction or proposed. Operating generation capacity totals 59.7 GW across 66 utility-scale plants of 100 MW and above. The largest is JER Green Hydrogen Solar PV Project (South Africa) (12.0 GW).
The largest owner-operators are Eskom Holdings SOC Ltd (25), Blue Crane Environmental (17) and Mainstream Renewable Power (8) — Eskom Holdings SOC Ltd alone is named on 15% of them. Half of South Africa's power plants in service predate 2015 (median commissioning year of the 65 with a known date), 32 came online in the past decade and the oldest still listed is Kelvin power station, dating from 1962. 99 are in the pipeline, led by JER Green Hydrogen Solar PV Project (South Africa) (12.0 GW), proposed. They account for 43% of every energy asset OverWatts maps in South Africa.

Frequently asked
- How many power plants are there in South Africa?
- OverWatts maps 172 power plants in South Africa — 0.6% of the world's mapped total, the 24th-largest national fleet of the 155 countries with any.
- What is the largest power plant in South Africa?
- JER Green Hydrogen Solar PV Project (South Africa), at 12.0 GW.
- How much power-generation capacity do South Africa's power plants have?
- About 59.7 GW operating across 66 plants, with a further 55.2 GW under construction or proposed. That covers utility-scale sites of 100 MW and above, so it sits below national installed capacity wherever distributed generation is large.
- Who owns the power plants in South Africa?
- Eskom Holdings SOC Ltd is named as owner or operator on the most — 25 of 172 (15%). Next are Blue Crane Environmental (17), Mainstream Renewable Power (8) and EDF Renewables (6).
- How old are South Africa's power plants?
- The median commissioning year is 2015, across the 65 in service with a known start date. The oldest still listed is Kelvin power station (1962); 32 came online in the past ten years.
- What new power plants are being built in South Africa?
- 99 projects are under construction or proposed. The largest are JER Green Hydrogen Solar PV Project (South Africa) (12.0 GW), Coega power station (3.0 GW) and Richards Bay (Eskom) power station (3.0 GW).
