This 2025 Market Intelligence Report by GreenCape analyzes investment opportunities in South Africa's large-scale renewable energy sector, focusing on private off-taker development and local component manufacturing. It details the shift from public procurement to private power purchase agreements (PPAs), the impact of electricity market liberalisation, and the systemic barriers posed by grid capacity constraints and policy uncertainty.

• The South African large-scale renewable energy market is shifting from public procurement via the REIPPPP to private off-taker agreements. The total installed capacity in 2024 was 15 GW, with projections suggesting the market will incorporate 32 GW by 2030.
• There is a significant investment opportunity in private renewable energy development for off-takers, estimated at R132 billion by 2030. This comprises R72 billion for solar PV (6 GW) and R60 billion for wind power (3.5 GW), averaging R26.4 billion per year.
• The liberalisation of the electricity market is being driven by the unbundling of Eskom into separate transmission, generation, and distribution entities. The National Transmission Company of South Africa (NTCSA) became operational in July 2024, and the National Electricity Distribution Company South Africa (NEDCSA) is expected to be operational by 2026.
• Severe grid capacity constraints are a primary barrier to new developments. There is currently zero grid capacity available for new large-scale renewable energy projects in the Northern Cape, Western Cape, Eastern Cape, and parts of the Free State, with capacity up to 2030 already forward-booked with 38 GW of projects.
• Corporate demand for renewable energy is driven by the need for energy security, cost stability compared to Eskom's above-inflation tariff increases, and international regulations like the EU's Carbon Border Adjustment Mechanism (CBAM). The mining sector ('basic materials') is the largest driver of demand, particularly for PPAs.
• Investment opportunities in local component manufacturing are estimated at R16 billion by 2030 (R3 billion per year), split between solar PV (R8.6 billion) and wind power (R7.6 billion). This is supported by the South African Renewable Energy Masterplan (SAREM), due for launch in early 2025.
• Local manufacturers face significant competitiveness challenges from low-cost imports, particularly solar PV modules. In 2023, solar PV module imports reached R42.4 billion, while exports were only R1.6 billion.
• Trade agreements such as SACU, SADC, and AfCFTA provide opportunities for exports. In 2024, exports of renewable components to SADC totalled R989.4 million (62% of total African exports), with Zambia, Namibia, and Zimbabwe as top destinations.
• Policy uncertainty persists regarding electricity trading licences, changing tariff structures, and the lack of municipal wheeling frameworks. Only six out of 257 municipalities have wheeling frameworks in development or implementation.
