Britain Must Enhance Security for Energy Infrastructure

Britain is urged to bolster security measures for its energy infrastructure, particularly wind farms, against threats both physical and cyber. A recent report warns of a tangible threat to critical undersea infrastructure, such as wind farm cables in the North Sea. This concern arises following a 2024 incident where a power cable was severed, exposing the vulnerabilities of these installations.

Produced by Public First in collaboration with the Royal United Services Institute for RenewableUK, the report highlights risks from malicious entities manipulating ship anchors. An expert from an offshore wind operator expressed that physical attacks pose greater concern than cyberattacks.

The report stresses the necessity for collaborative efforts with other nations to enhance infrastructure protection. Recommendations include creating multiple connection points for energy installations, such as integrating a North Sea power grid. Strengthening cybersecurity for wind and solar farms is essential, in light of an increase in attacks.

Recent incidents underscore these vulnerabilities. A coordinated attack in December on over 30 wind and solar farms in Poland demonstrated that even less sophisticated methods could significantly disrupt renewable energy infrastructure. The report advocates for clearer procedures to safeguard smaller assets from decentralised attacks and improved coordination to prevent system-wide contagion.

While acknowledging the need for improved protections, the report underscores the importance of transitioning to renewable energy to reduce dependence on imported gas and mitigate price volatility. Scenario simulations indicate that Britain’s energy system is resilient, even with potential individual asset damage; however, the overriding concern remains price fluctuations.

The ongoing conflict in Iran amplifies these issues, with experts suggesting that unresolved tensions may lead to unacceptable consumer costs and overall economic impacts. The country must focus on maximising homegrown clean energy generation to enhance resilience against global geopolitical shocks.

In alignment with NATO commitments, the UK aims to allocate 5 per cent of its GDP for defence, including 1.5 per cent specifically for the protection of critical infrastructure by 2035. The report advocates for the UK to take the lead in ensuring that spending on energy system resilience is factored into NATO targets without detracting from military or defence expenses.

Moreover, there is a pressing need for additional gas and electricity storage, coupled with a physical stockpile of spare parts to facilitate the repair of damaged infrastructure.
