TT Club urges power failure preparedness into everyday operations

TT Club has warned that power outages, whether stemming from grid instability, climate-related incidents or technical failures can trigger widespread disruption across transport and logistics networks.

As energy infrastructure ages and dependence on digital and electrically powered systems grows, the risk of disruption is increasing, with serious commercial, safety and insurance consequences. The 2025 Iberian Peninsula blackout clearly demonstrated how the failure of a single transformer was able to bring transport operations in several countries to a standstill for hours.

Renewable transition sharpens focus on power reliability

The integration of renewable energy sources is adding complexity to the challenge of ensuring a stable and continuous power supply. Ongoing uncertainty in global climate and energy policy—including slowdowns in international efforts to decarbonise shipping, may further delay the investment and coordination needed to strengthen future energy networks.

Meanwhile, ports are becoming ever more reliant on electricity to operate cranes, pumps, security systems and digital infrastructure, leaving them particularly exposed when power failures occur.

To strengthen resilience and ensure business continuity during power disruptions, TT Club outlines the following key actions for ports and terminal operators:

• Conduct a criticality assessment to identify essential systems and acceptable downtimes.
• Add redundancy to IT infrastructure, ensuring vital systems and communication channels remain functional during outages.
• Establish robust emergency power and fuel plans, including maintained generators and backup batteries.
• Develop and train staff in safe shutdown procedures to prevent injury and equipment damage during a blackout.
• Strengthen communication resilience, such as maintaining VHF radios and paper-based contact lists in case networks fail.
• Plan for recovery, recognising that restarting high-voltage systems must be managed carefully to avoid further damage.
• Operational readiness keeps cargo moving when the lights go out
• Proactive planning – including regular drills and cross-departmental coordination – remains the most effective way to safeguard operations and personnel in the event of power loss.

Power outages are no longer rare or isolated, they’re an operational reality that every port and terminal must factor into its resilience planning. Preparing for both local and widespread blackouts, rehearsing safe shutdowns, and ensuring alternative communication methods are in place are essential steps to protect people, assets, and supply chains when the unexpected happens.
