In 2025, the UK experienced nearly 25,000 unplanned power disruptions, a staggering 42% increase from 2021 and a dramatic rise from the mere 640 outages recorded in 2015.
We’re not just talking about minor inconveniences, these disruptions affected millions of homes and businesses, cost the economy hundreds of millions in lost productivity, and in some cases, put lives at risk when critical services lost power.
As we move into 2026, the question isn’t whether the UK’s power infrastructure is under strain, it’s what we’re going to do about it.
The Perfect Storm Hitting the UK Grid
Three converging factors are creating unprecedented pressure on the UK’s electricity network:
1. Ageing Infrastructure
Much of the UK’s power infrastructure was built decades ago and is struggling to meet modern demands. The retirement of coal fired plants and nuclear facilities has removed significant baseload capacity, while replacement infrastructure hasn’t kept pace.
2. Extreme Weather Events
The Met Office documented a 320% increase in major UK storms from 2010 to 2015 and 2015 to 2020, and the trend has only intensified. Fallen trees, flooding, and wind damage to power lines are now regular occurrences. The North West region alone suffers around 12,500 outages per year, over 1,000 per month, largely due to weather related damage.
3. Rising Electricity Demand
As we electrify transport and heating to meet net zero targets, electricity demand is climbing at the same time that generation capacity faces constraints. This creates the worst possible scenario: more demand, less supply, and an increasingly fragile system.
THE SOLUTION: Distributed Energy Generation and Storage
Traditional centralised power generation, where massive plants send electricity across hundreds of miles of transmission lines, is showing its vulnerabilities. Every storm, every grid failure, every voltage fluctuation can cascade into widespread outages.
The solution lies in distributed energy systems built around two key technologies:
A) Solar PVs: Generating Power Where It’s Needed
Solar photovoltaic systems allow homes, businesses, and communities to generate their own electricity. The benefits for grid resilience are significant:
That last point brings us to an inspiring example from Switzerland, where startup Sun Ways successfully deployed the world’s first removable solar panels between active railway tracks. In April 2025, they installed 100 meters of panels in Neuchâtel, demonstrating how we can think creatively about unused space. Switzerland’s 5,317 km of railway lines could potentially generate 1 terawatt hour annually, 2% of the country’s total energy needs, all without taking a single additional square meter of land.
We don’t need to choose between energy infrastructure and other land uses, we can integrate solar into existing infrastructure, making every surface work harder.
B) BESS: The Missing Link for Grid Stability
Solar PVs alone can’t solve the resilience problem. The sun doesn’t shine at night, and it certainly doesn’t shine during evening peak demand. This is where Battery Energy Storage Systems become critical.
BESS installations serve multiple functions that directly address the UK’s grid challenges:
Grid Scale Resilience: Large BESS facilities can provide instant backup power during disruptions, preventing cascading failures and giving the grid operator time to balance supply and demand. When Spain and Portugal suffered their devastating 10 hour blackout in April 2025, insufficient storage capacity was a key factor in the prolonged outage, a stark reminder for the UK as we enter 2026.
Frequency Regulation: The UK’s National Energy System Operator must keep grid frequency between 49.5Hz and 50.5Hz. BESS can respond in milliseconds to frequency fluctuations, far faster than traditional power plants. This becomes increasingly critical as we integrate more variable renewable generation.
Peak Shaving: BESS can charge during periods of low demand and high renewable generation, then discharge during evening peaks. This reduces the need for expensive gas peaker plants and helps prevent the capacity shortfalls that led to Capacity Market Notices in early 2025, including 8 January when balancing costs exceeded £21 million.
Local Energy Independence: For businesses and communities, local BESS paired with solar PVs creates genuine energy independence. When the grid fails, as it did for 180,000 customers for over 24 hours during Storm Arwen in 2021, these systems can island from the grid and continue operating.
The Business Case Is Compelling
Looking at 2025’s rising outage rate, the economic argument for solar PVs and BESS has never been stronger:
Risk Mitigation: With power cuts having occurred at a rate of 66 per day nationally in 2025, the question isn’t if you’ll experience an outage, but when. For businesses, a single outage can cost thousands or even millions in lost revenue, damaged equipment, and data loss. A medium-sized data centre experiences over three downtime events per year, with average cuts lasting over three and a half hours.
Energy Cost Certainty: Solar PVs generate electricity at a fixed cost for 25+ years. In an era of volatile energy prices, this provides invaluable certainty for financial planning. BESS allows you to buy electricity when it’s cheap (often during high renewable generation periods) and use it when prices spike.
Revenue Generation: Grid-scale and commercial BESS installations can participate in frequency response markets, earning revenue by providing grid balancing services. Some businesses are finding their BESS investments pay for themselves through grid services alone, with the resilience benefits as a bonus.
Future Proofing: As the grid becomes increasingly congested, connection costs and wait times for new developments are soaring. Installing solar PVs and BESS now secures your energy future and may even allow you to reduce your grid connection requirements for expansions.
What Needs to Happen Next
The technology exists, the business case is proven, what’s needed now is:
1. Accelerated Deployment: The UK needs to treat distributed solar and storage with the urgency it deserves. Planning barriers for solar installations should be streamlined, and grid connection processes for BESS need to be faster and more predictable.
2. Smart Integration: We should follow Switzerland’s example and look for creative deployment opportunities. Railway tracks, car parks, reservoirs, canal sides, roadside verges, there are thousands of unused spaces that could host solar generation without competing with other land uses.
3. Investment in Local Resilience: Communities, particularly those in high outage regions like the North West and Scotland, should be supported in developing local solar and storage microgrids. These provide resilience not just for individual buildings but for entire neighborhoods.
4. Market Reform: Current electricity market structures were designed for centralised generation. We need regulatory changes that properly value the resilience, flexibility, and grid support services that distributed solar and BESS provide.
The Bottom Line
The UK’s electricity infrastructure is under unprecedented stress. The 25,000 outages experienced in 2025 represent more than just numbers, they’re millions of disrupted lives, billions in economic losses, and a stark warning about our energy future heading into 2026 and beyond.
We can’t prevent every storm or instantly rebuild the entire grid, but we can make the system fundamentally more resilient by distributing generation and storage across thousands of sites rather than relying on a handful of large plants connected by vulnerable transmission lines.
Solar PVs and BESS aren’t just about meeting net zero targets or reducing carbon emissions, though they do both admirably. They’re about building an energy system that’s robust enough to handle the challenges of the 21st century: extreme weather, rising demand, and the transition away from fossil fuels.
The Swiss turned railway tracks into solar power plants in 2025. As we move through 2026, we should be asking: what opportunities are we missing? What infrastructure could work harder? What could we power tomorrow that we’re not powering today?
Because if there’s one thing the 2025 data makes crystal clear, it’s that the status quo isn’t working, the grid is becoming less reliable, not more. And every home, business, and community that takes control of its own energy future through solar and storage makes the entire system more resilient.
The future of UK electricity isn’t just renewable, it’s distributed, it’s resilient, and it starts with the decisions we make today.
