Britain's electricity distribution networks are increasingly vulnerable to "abnormal" weather events, which are fast becoming the "new normal" and posing a significant threat to the reliability of the UK's power supply1. This shift demands a proactive and resilient approach to energy management.
Managing your home's energy should be straightforward, even when the wider grid faces challenges. Fuse Energy offers clear pricing and tools to help you understand your usage, giving you more control. Click here to switch to Fuse Energy today.
Climate change and infrastructure vulnerability
The UK's energy infrastructure, much of which was built decades ago, faces unprecedented challenges from a changing climate. This escalating pattern places immense strain on the grid, which faces increasing vulnerability under these conditions.
Key weather threats: rain, heat, and wind
Intense rainfall, sustained high temperatures, and powerful winds are key threats directly impacting the physical infrastructure of electricity networks. An analysis by energy management firm VisNet highlights how these conditions significantly threaten power reliability. For instance, heavy rainfall can permeate the ground and seep into underground cables through existing cracks, leading to faults. Similarly, extreme heat can cause underground distribution cables to expand, warping the cable or cracking its insulation.
What are pre-faults?
"Pre-faults" are sudden current spikes triggered by a breakdown of insulation on an electricity line. These events indicate underlying network stress and highlight the need for improved monitoring to prevent disruptions.
Heatwaves and underground cable stress
Heatwaves are making pre-faults more frequent. Dr David Clements, Data Analytics Manager at EA Technology, VisNet's parent company, stated, "We know from conversations with electricity operators in continental Europe that in the days following extreme heat, networks can experience very significant spikes in pre-fault numbers." He further explained, "They could be the result of underground distribution cables expanding when the temperature rises, which then warps the cable or causes its insulation to crack".
The impact of sustained rainfall vs single storms
VisNet data also links a rise in pre-faults to winter storms and prolonged precipitation. While a one-off event like a storm causes a rise in pre-fault levels, Clements observed that "the data from the UK’s 2024/25 storm season clearly shows a one-off event like a storm causes a rise in pre-fault levels - but nowhere near to the same extent as sustained rainfall". Sustained rainfall can seriously disrupt electricity supplies if operators overlook their distribution network.
Proactive detection vs reactive repairs
The increasing frequency of pre-faults necessitates improved network monitoring to prevent disruptions. Historically, fault-finding was slow and reactive, often leaving customers without power. Advanced monitoring systems provide improved network visibility, allowing for the detection and precise location of pre-faults. This enables a proactive approach to repair work, significantly reducing the time and effort needed to fix issues before they escalate into outages.
Avoiding regulatory penalties and customer disruptions
For electricity operators, preventing disruptions is not just about service quality; it also helps avoid regulatory penalties. Ofgem, the energy regulator, can impose penalties for network disruptions and customer minutes lost due to power outages. Proactive maintenance, informed by grid-edge intelligence, is crucial for maintaining network reliability and avoiding these consequences.
Empowering homeowners for grid stability
Individual homeowners have a crucial role to play in building a more resilient energy system. By adopting smart energy solutions, households can contribute to overall grid stability and reduce their vulnerability to power disruptions. This empowerment shifts the narrative from feeling powerless against large-scale issues to actively participating in solutions.
The role of smart energy management
Smart energy management tools, such as smart meters and home energy management systems, provide homeowners with greater control and visibility over their energy consumption. These technologies allow for optimised energy use, particularly during periods of high demand or grid stress, and can integrate with localised generation and storage solutions like solar panels and batteries. This intelligent approach helps balance supply and demand, making the entire system more robust.
Fuse Energy challenges the scarcity mindset by offering solutions that build grid resilience and empower homeowners. Our approach involves rebuilding the energy system from scratch, focusing on deploying cleaner energy and optimising the grid. This vision aims for a future with abundant energy, where reliability concerns diminish for homeowners.
Fuse's smart energy management tools provide homeowners with control and capability. Through our app, customers gain insights into their energy usage, helping them navigate potential grid disruptions and contribute to stability. This shifts the balance of power into the customer's hands, offering a tangible advantage in managing their home energy.
