Eskom Using Drones to Support 33,369km of Critical Infrastructure

Why It Matters

Frequent, low‑cost drone inspections lower Eskom’s maintenance spend while enhancing grid resilience, a critical factor for South Africa’s energy security and economic stability.

Key Takeaways

• Drones replace costly helicopter inspections
• 33,369 km of lines now monitored more frequently
• Infrared drones detect sabotage and equipment faults
• Inspection robots patrol lines continuously
• RT&D unit drives Eskom’s tech innovation

Pulse Analysis

The adoption of drone technology by Eskom reflects a broader shift in utility asset management toward autonomous, data‑rich inspections. Traditional helicopter surveys, while effective, are prohibitively expensive and limit inspection frequency. By deploying drones equipped with high‑resolution and infrared sensors, Eskom can capture granular thermal imagery that reveals hot spots, line sag, and vegetation encroachment in real time. This granular data feeds predictive maintenance models, allowing crews to prioritize repairs before outages occur, ultimately reducing downtime and operational costs across the nation’s sprawling grid.

Security concerns have also driven Eskom’s drone strategy. In 2022, the utility introduced infrared‑capable drones to counteract sabotage by criminal syndicates targeting power infrastructure. Coupled with intelligent CCTV systems, these aerial assets provide a layered surveillance network that can spot unauthorized activity, assess damage instantly, and trigger rapid response teams. The integration of AI‑enhanced analytics further refines threat detection, turning raw footage into actionable intelligence and safeguarding both urban and rural substations.

Beyond aerial platforms, Eskom’s RT&D division is pioneering ground‑based innovations such as the Powerline Inspection Robot. Patented in South Africa and the United States, the robot traverses live conductors, delivering continuous high‑definition visual data while withstanding harsh electromagnetic and weather conditions. Partnerships with universities and technology funds accelerate the rollout of these solutions, positioning Eskom as a regional leader in smart‑grid modernization. The combined drone‑robot ecosystem promises lower maintenance expenditures, heightened reliability, and a more sustainable energy future for South Africa’s industrial and residential consumers.
