Renewables-Battery Scenario Proposed for Saving Ferrochrome While Sustaining Eskom and Reform ...

Why It Matters

Saving the smelters protects up to 68 000 jobs and R100 billion in export revenue while forcing critical reforms of Eskom’s financially strained utility.

Key Takeaways

• Only four of 48 smelters remain operational
• Ferrochrome accounts for 19% of global supply
• PV+BESS needs R157bn, R77bn subsidy
• Subsidy recovers in ~4 years vs Eskom subsidies
• Support conditional on Eskom unbundling and transparency

Pulse Analysis

South Africa’s ferrochrome industry, responsible for roughly one‑fifth of global output, is teetering on the brink due to Eskom’s high electricity tariffs. The sector, anchored on 72% of the world’s chrome ore reserves, employs tens of thousands and generates over R100 billion in annual exports. Yet the utility’s 62 c/kWh offer to smelters, far below its 196 c/kWh cost, threatens a revenue shortfall that could accelerate Eskom’s already precarious balance sheet, potentially prompting a “death‑spiral” of coal‑plant extensions.

The proposed renewable‑battery pathway envisions 8 GW of solar PV paired with 2 GW/24 GWh of battery storage, demanding R157 billion in total investment. A one‑off R77 billion government subsidy would bridge the cost gap, delivering electricity at the target 62 c/kWh. Financial modelling shows the subsidy would be recouped in about four years through avoided Eskom payouts, a stark contrast to the projected R261 billion cumulative subsidy required if Eskom continues direct support. This makes the PV+BESS model not only environmentally cleaner but also fiscally superior.

Policy-wise, the authors recommend establishing Eskom Green as a standalone, possibly public‑private, entity to own and operate the renewable assets, insulated from Eskom’s coal‑centric credit risk. Coupled with an export royalty on un‑beneficiated chrome ore, the plan creates a four‑to‑six‑year bridging framework that aligns industrial competitiveness with energy sector reform. By conditioning financial aid on transparent tariff structures and a credible unbundling timeline, South Africa can safeguard jobs, retain export earnings, and advance its broader clean‑energy transition.
