Aggreko on Energy Security for Mines in Africa & the Strengthening Case for Hybrid Power

Why It Matters

By lowering exposure to volatile fuel prices and meeting ESG expectations, hybrid power improves mining profitability and unlocks better financing terms, making it a strategic imperative for African resource producers.

Key Takeaways

• Diesel price spikes add millions to mine operating costs.
• Hybrid solar‑storage cuts diesel use up to 40%.
• Solar‑plus‑storage costs $0.06‑$0.20/kWh vs diesel $0.15‑$0.50.
• OPEX‑based contracts lower upfront capital for hybrid projects.
• Hybrid systems boost uptime above 99.9% and reduce CO₂.

Pulse Analysis

The recent surge in Brent crude—rising more than 20% in weeks—has sent diesel costs at remote African mines soaring, with transport, security and handling inflating delivered fuel prices well above global benchmarks. For operators, this volatility translates directly into higher operating expenditures, eroding margins on commodities that already face price pressures. As mining projects increasingly operate off‑grid, the reliance on a single fuel source becomes a strategic liability, prompting executives to reassess energy procurement as a core component of cost control and risk management.

Hybrid power offers a pragmatic answer by blending solar photovoltaics, battery storage, and flexible thermal generators into a single, controllable system. Cost analyses show solar‑plus‑storage can supply power at $0.06‑$0.20 per kilowatt‑hour, markedly cheaper than diesel’s $0.15‑$0.50 range, while also displacing up to 40% of diesel consumption. Beyond economics, these configurations deliver reliability scores above 99.9% and cut CO₂ emissions by 50,000‑100,000 tonnes annually, aligning mines with the ESG criteria increasingly demanded by investors, lenders and off‑take partners. The broader African microgrid market, valued at over $10 billion today, is set to exceed $21 billion by 2030, with mining driving a substantial share of that growth.

Financing remains the chief hurdle, but OPEX‑oriented models—such as power purchase agreements and pay‑per‑kilowatt‑hour contracts—allow mines to adopt hybrid solutions without large upfront capital outlays. Experienced energy partners provide lifecycle services, from design and remote monitoring to fuel‑mix optimisation, mitigating operational complexity for mining teams focused on extraction. As the continent’s mineral wealth underpins the global energy transition, forward‑looking operators that embed hybrid power into their long‑term strategy will secure cost stability, regulatory compliance, and a competitive edge in a market where energy security is as critical as ore grade.
