South Africa is poised for a record year in utility-scale renewable energy and battery storage installations, with projections indicating 5,252 MW of new capacity in 2026 across 34 financial closures. This surpasses the 3,562 MW recorded in 2024. While ambitious, even a partial conversion of the pipeline would make 2026 exceptional by historical standards. The pipeline is primarily driven by public procurement processes, including bid windows six and seven of the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) and bid window two of the Battery Energy Storage Independent Power Producer Procurement Programme (BESIPPPP). These programs account for an estimated 3,112 MW across 20 projects, representing about 60% of the projected capacity.
A significant trend is the rise of the private commercial and industrial (C&I) market, with licensed electricity traders playing a crucial intermediary role between independent power producers (IPPs) and corporate electricity users. Of the six confirmed C&I closures in 2026, five are trader-intermediated, accounting for 1,219 MW, which is approximately 80% of the total 1,519 MW confirmed C&I capacity. Notable projects include Anthem's 475 MW Notsi project, Mulilo's 380 MW Beaufort West project, Etana Energy's 219 MW Orkney project, Lyra Energy's 255 MW Thakadu project, and PowerX's 25 MW Parsons PV project. SOLA's 300 MW Naos 1 PV plant, paired with 660 MWh of battery storage, has a direct bilateral off-take arrangement with Sasol and Air Liquide.
This growth indicates a structural recovery, not just a cyclical one, attributed to policy continuity after a period of uncertainty between 2015 and 2018 when Eskom halted IPP energy purchases. The domestic capital market is demonstrating strong depth, underwriting projects up to 475 MW without foreign commercial debt, with all closed projects securing financing from South African commercial banks and development finance institutions. Mulilo's 337 MW Middlepunt PV project achieved the lowest tariff under REIPPPP to date at $0.027/kWh. While large-scale solar dominates, two battery projects highlight the increasing bankability of storage assets in South Africa.
Energy security is a key driver for businesses, with Sibanye-Stillwater signing a 10-year power purchase agreement with Etana Energy to supply 600 GWh of renewable electricity annually, covering over 35% of its targeted renewable capacity. This deal is expected to cut carbon emissions by about 32,000 tonnes annually and provide lower-cost energy to its South African operations. Additionally, African Rainbow Energy has expanded its stake in SOLA Group to 83% in a $1.2 billion deal, increasing its combined renewable energy portfolio to nearly 2,000 MW of solar and battery storage capacity, with projects supplying major corporations like Amazon, Sasol, and Vodacom. The National Transmission Company South Africa has confirmed 31.7 GW of generation customer connections at or beyond the budget quotation phase, including 26 GW of utility-scale PV and wind, emphasizing the need for flexible generation to complement variable renewables.
