Private Power Rewires South Africa

Coverage from Africa Sustainability Matters, Pinsent Masons, and others

Private Power Rewires South Africa topic image

South Africa’s energy transition is increasingly being financed by private companies, with corporate power purchase agreements expected to support most new utility-scale solar and wind capacity in 2026.

The shift is occurring alongside continued coal dependence and a major need for transmission expansion, which could determine whether renewable growth delivers broader industrial benefits. Chinese investors and manufacturers are also becoming important partners in equipment supply, infrastructure, and emerging green-fuel projects.

Key Issues

Corporate buyers are becoming the main renewable financiers

Corporate power purchase agreements are expected to support 73% of South Africa’s 2.3 GW of solar and wind additions in 2026, overtaking government auctions for the first time. This shifts renewable expansion toward private procurement and corporate demand.

Transmission is the binding constraint on wider transition gains

Developers and corporate buyers are planning additional clean-power investment, but insufficient transmission capacity threatens project connections and the industrial benefits of renewable growth. The state’s plans include roughly 14,500 km of new transmission lines by 2034, making delivery a critical dependency.

Coal still dominates, despite a planned long-term shift

Coal supplied 78% of South Africa’s electricity in 2025, so the transition remains heavily dependent on the retirement and replacement of ageing coal capacity. Policy targets and transition scenarios point to declining coal use, including 8 GW of retirements by 2030 and a possible 21% coal share by 2050.

Weakening

Drawn from 3 articles

High costs and external supply dependence limit industrial gains

South Africa’s clean-industrial ambitions face electricity prices substantially above mainland China’s and heavy reliance on Chinese solar and battery imports. Chinese manufacturers are being courted for local equipment production, but the evidence presents localization as an objective rather than an achieved outcome.

Key Numbers

35% percent

increase in small-scale solar investment

South Africa · 2025

South Africa attracted US$5.4 billion in renewable-energy investment in 2025, remaining sub-Saharan Africa’s largest market. Investment declined 41% from US$8.6 billion in 2024. Utility-scale solar investment fell 57% to US$1.4 billion, onshore wind investment declined 30% to US$2.1 billion, and small-scale solar investment rose 35% to US$1.8 billion.

78% percent

share of electricity supplied by coal

South Africa · 2025

Coal supplied 78% of South Africa’s electricity in 2025, down from 90% in 2015. Under BloombergNEF’s Economic Transition Scenario, electricity consumption rises 35% to 319 terawatt-hours by 2050. Solar, wind and battery storage would supply 69% of demand, while coal’s share would fall to 21% as aging plants retire.
