Energy prices across the UK remain unpredictable, and national grid stability is under pressure. Businesses running factories, warehouses, and logistics centres are searching for smarter ways to reduce risk and control costs. That’s where a Battery Energy Storage System (BESS) comes in.
By pairing rooftop solar with industrial solar batteries, UK companies can store excess renewable generation, power evening shifts, and protect against outages. In short, industrial solar battery storage has moved from “nice to have” to “business-critical.”
And at Smartly Energy, we design and install integrated systems that deliver cost savings on your electricity bill, stability, and sustainability for UK industry.
The State of Energy Storage in the UK

The UK is one of Europe’s leaders in large-scale battery deployment. Current capacity has passed 5 GW of operational projects, with a further 95–127 GW in the pipeline depending on which data source you look at.
- Average project sizes have increased significantly, with many now in the 50–100 MW bracket.
- BESS UK (battery energy storage systems) are no longer limited to pilot projects – multi-GW developments are underway.
- England leads installations (over 80%), but Scotland, Wales, and Northern Ireland are quickly expanding their share.
This rapid growth highlights the importance of BESS sites not only for balancing renewables on the grid but also for industrial users who need resilient, cost-effective energy.

Why Energy Storage Matters for UK Industry
Reducing Costs & Stabilising Tariffs
Factories and warehouses face high demand charges and volatile tariffs. By using storage battery electricity systems for peak demand shaving, businesses can shift loads of clean energy away from expensive periods and stabilise long-term budgets.
Maximising On-Site Solar
Battery energy storage systems UK allow industrial sites to capture surplus solar generation during the day and use the power supply for evening operations. Cold storage, lighting, and HVAC all benefit from this flexibility.
Supporting EV & Forklift Fleets
Forklift trucks, HGV charging bays, and employee EV charging points can all be powered from industrial solar batteries, reducing reliance on grid imports which skyrocket your energy bill.
Resilience & Grid Security
While not a full replacement for diesel backup, industrial solar battery storage can protect critical circuits during short grid outages, improving resilience and compliance.
UK Government Strategy & Market Drivers
- The UK Battery Strategy (2023) commits over £2 billion in funding from 2025 – 2030.
- Programmes like the Faraday Challenge, the UK Battery Industrialisation Centre, and the Advanced Materials Centre are driving R&D and supply chain capacity.
- 2022 law changes have sped up planning permission for larger BESS sites, supporting industrial adoption.
- Net Zero 2050 targets require large-scale deployment of both solar power and storage.
Key Challenges Facing Battery Energy Storage Systems UK
Grid Connection & DNO Queues
Grid bottlenecks and constrained export nodes are slowing some projects. Smartly Energy designs for self-consumption, export-limited operation, and integrates storage battery solutions to protect ROI.
Supply Chain & Skills
The global demand for lithium, cobalt, and nickel continues to create supply chain pressure. Skills shortages in UK engineering add further delays, though government investment is helping.
Market Regulation & Charges
The rules for UK battery storage are evolving, with changing demand charges and uncertainty over balancing markets. Robust system design and flexibility are key.
Insurance & Fire Compliance
Insurers demand clear fire safety measures for battery energy storage systems UK. Smartly ensures compliant layouts, fire breaks, and monitoring systems from the outset.
Industrial Solar Batteries – The Perfect Fit for Warehouses & Factories
Industrial buildings have two major advantages: large roof areas and high daytime demand. Add storage, and the benefits multiply.
- Industrial solar batteries can capture surplus generation during peak solar hours.
- Stored power can then cover evening operations, refrigeration, or night-shift machinery.
- When users can store and consume energy on site, they face fewer issues with export restrictions from the DNO.
- Example: a 500 kWp solar system paired with a 1 MWh storage battery could save over £100,000 per year in energy costs.

The Future of UK Battery Storage
- Analysts expect operational capacity to exceed 10 GW within a few years.
- Larger, multi-MW BESS sites will continue to dominate, but smaller industrial systems will grow rapidly.
- The co-location of UK battery storage with solar and wind will become the norm.
- Industrial adoption will accelerate as energy prices remain volatile and sustainability reporting becomes mandatory.

FAQs
What is BESS UK and how does it work?
BESS stands for Battery Energy Storage Systems UK. These systems store electricity in large batteries, typically lithium-ion, and release it when demand or costs are high.
How much battery storage does a factory need?
It depends on energy demand, operating hours, and solar capacity. Smartly Energy models every case to size the right industrial solar battery storage system for maximum ROI.
What are the main costs of industrial solar batteries?
Costs vary from £500–£800 per kWh installed for large systems, but long-term savings and tariff avoidance often offset this within 5–8 years.
Do batteries provide full backup during outages?
Not always. While industrial solar batteries can cover critical loads, full-site backup usually requires a hybrid of storage and generators.
How long do industrial storage batteries last?
Most storage battery systems have warranties of 10–15 years, with performance guarantees ensuring 70–80% capacity after a decade.
