Rationale: mining in remote, politically unstable regions. Imagine a copper mine in the DRC, where national grids are unreliable and fuel convoys are targets of disruption. The mine has historically relied on diesel generators, experiencing costly outages and high emissions. By deploying FlowGen container microgrids: • Zero outage downtime: Critical systems run seamlessly, even during grid or supply disruption. • Operational autonomy: Energy independence reduces exposure to supply chain risks. • Modular expansion: Additional containers can be added as the mine scales. • Strong ROI: Savings derive from uninterrupted output, not just fuel cost reductions. 1. Diesel Generator: ~60 €c/kWh 2. Smart renewable microgrid for mining offgrid (Mobile Green Center): ~12 €c/kWh 3. Smart renewable microgrid for offshore oil platforms: ~7–8 €c/kWh. Here, FlowGen’s solution transitions energy from a reactive dependency to proactive resilience infrastructure. Strategic implications for mining executives • Quantify outage impact: Assign direct financial metrics to downtime and compare against the cost-benefit of resilient microgrid deployment. • Holistic risk evaluation: Factor in political, climatic, and logistical risks. FlowGen’s autonomous, hybrid microgrids respond to diverse disruption vectors. • Phased implementation: Begin with mobile container systems for pilot and expansion—Leverage FlowGen’s modularity to scale alongside production phases. • Regulatory and logistics coordination: Engage early with local permitting and logistics, FlowGen’s compact design simplifies installation and helps navigate local hurdles. From sustainability to strategic imperative FlowGen reframes microgrids from green concepts to critical infrastructure for mining operations under pressure. • Operational resilience outweighs environmental branding in high-risk settings. • Modularity and deployability align with the dynamic, rugged realities of mining projects. • Autonomous infrastructure reduces reliance on vulnerable systems and enables continuity in the face of disasters, unrest, or logistical failures. In this landscape, microgrids are more than energy—they are mission assurance. Conclusion For African miners, power is no longer just an input; in volatile mining contexts, it serves as a safeguard. Compact, mobile, hybrid microgrid systems offer a powerful blueprint for mining operators who cannot afford interruption. We deliver resilience, reliability, and a tangible competitive advantage. The real question for mining executives is: can you afford the risk of power failure when you could deploy autonomy with a secure microgrid energy supply instead? n

• Diesel vulnerability: supplies are logistics-dependent and susceptible to political instability or environmental disruption. Microgrids mitigate these by: • Ensuring continuity: Whether autonomous or grid-connected, microgrids equipped with flow-diverse power sources keep operations running. • Eliminating fuel constraints: By blending wind, solar, and storage, FlowGen microgrids reduce, if not eliminate, dependence on fuel deliveries. • Scaling with operations: Modular design means additional capacity can be added as mines expand. FlowGen’s resilience advantage in remote and risky environments Mobile deployability FlowGen’s containerised systems can be swiftly transported and commissioned with minimal civil works—critical for remote sites undergoing exploration or requiring interim power during fuel- supply disruptions. Scalable and modular Whether powering a single shaft or entire site complexes, FlowGen systems scale from kilowatts to multiple megawatts. Integrating wind, solar, and storage, along with sophisticated energy management, enables tuning to site-specific conditions and risk tolerance. Robust design Lightweight materials, an aerodynamic rotor design, and automotive-grade manufacturing ensure durability in remote and harsh environments. FlowGen’s turbines maximise energy in low- wind environments while minimising footprint and noise.
