South Africa’s push to expand domestic wind turbine manufacturing has brought a familiar industrial policy question back into focus: how much should renewable-energy developers be required to source locally, and what happens if those requirements increase the cost of building new power plants? A warning from a major wind industry player, reported by News24 on October 12, puts the tension between manufacturing ambitions and affordable electricity at the centre of the debate. The outcome matters for both the local businesses expected to benefit from new orders and the developers responsible for bringing additional generation capacity online.
Local-content requirements are intended to direct a share of renewable-energy investment towards South African manufacturers, suppliers and workers. Wind projects can support domestic production of components such as turbine towers, alongside civil engineering, transport, installation and maintenance services. South Africa has already developed some capacity in wind tower manufacturing, with previous procurement rounds helping create demand for local suppliers. However, establishing factories and maintaining skilled workforces requires a sufficiently steady pipeline of projects, not simply a target for locally sourced equipment.
The cost concern arises because wind turbines depend on specialised components and international supply chains operating at significant scale. If locally manufactured equipment costs more or cannot be delivered in the required quantities and timeframes, developers may face higher capital costs or delays. Those costs can affect the tariffs at which projects are willing to supply electricity, particularly in competitive procurement programmes. In 2022, Rand Merchant Bank argued that locally made components could cost 20% to 50% more than imported alternatives in some cases, reflecting differences in production scale. That earlier assessment illustrates the concern, although the actual cost difference varies by component and supplier.

The counterargument is that relying heavily on imported turbines and components limits the domestic economic benefits of South Africa’s renewable-energy expansion. Local manufacturing can create industrial capabilities, support technical skills and give South African companies opportunities to supply future projects. But those benefits depend on whether manufacturers can secure enough predictable demand to justify investment. Research on South Africa’s wind industry has highlighted the risks of using localisation requirements without the procurement certainty and industrial support needed to sustain local production. The closure of DCD Wind Towers in 2019, after a period of weak demand, demonstrated how gaps between procurement rounds can undermine manufacturing capacity.
The policy challenge is therefore not simply choosing between local jobs and cheaper equipment. South Africa needs a framework that gives domestic manufacturers a credible market while allowing wind projects to proceed at competitive costs and on workable schedules. That requires clarity about which components can be manufactured locally, consistent procurement timelines and a realistic assessment of suppliers’ capacity. The specific proposals and concerns raised in the latest industry warning will help determine how that balance is approached. The measure of success will be whether localisation creates durable industrial activity and employment without making it harder or more expensive to add the wind generation the country needs.
