Rising energy costs remain one of the most pressing challenges for UK businesses. Market volatility, global supply disruptions, and seasonal demand surges are pushing electricity prices to record highs. For business owners, this creates uncertainty and reduces long-term financial planning.
One solution gaining significant traction is battery storage for commercial buildings, which allows businesses to store electricity when prices are low and use it during peak price periods. By pairing battery technology with on-site solar PV, companies can not only reduce energy bills but also improve resilience against market volatility. EvoEnergy has helped organisations across the UK integrate commercial solar power battery storage, providing a reliable pathway to lower costs and stronger energy security.
Key Takeaways
- Cost protection: Charge the battery when electricity is cheaper; discharge when tariffs spike.
- Solar maximisation: Store surplus solar and use it later instead of exporting at lowest value.
- Peak shaving + load shifting: Reduce peak demand and move consumption to lower-cost periods.
- Resilience: Batteries can support critical operations during grid instability (subject to system design).
- UK support: Depending on your setup, schemes like the Smart Export Guarantee (SEG) can pay for exported renewable electricity, and businesses may be able to claim relevant capital allowances on qualifying plant and machinery.
Why Are Energy Prices So Volatile in the UK?
UK electricity prices can change quickly due to wholesale market movements and peak-demand periods (especially seasonal peaks). If you buy most of your power directly from the grid at variable or time-dependent rates, your costs are exposed to these spikes.
Companies that rely solely on the grid have little protection against these swings. A commercial battery system provides a way to store cheaper electricity during off-peak times, protecting businesses from price hikes and stabilising energy budgets.
What Is Battery Storage, and How Does It Work?
A commercial battery energy storage system (BESS) is an on-site battery that stores electricity and supplies it later to reduce grid costs and improve energy resilience.
For businesses with solar installations, commercial solar power battery storage provides an even greater advantage. Instead of exporting excess solar energy back to the grid at relatively low rates, companies can store it for times of peak demand. This practice, known as “peak shaving,” which reduces your maximum grid demand by using the battery during peaks, or “load shifting,” which moves electricity use from expensive periods to cheaper ones (by charging earlier).
How does it work in 4 steps?
- Charge from the grid when tariffs are lower, and/or from surplus on-site solar PV.
- Store energy on-site until it’s valuable to use.
- Discharge during high-tariff periods to reduce expensive grid import.
- Optimise automatically using an energy management system that tracks demand, tariffs, and generation.
How Battery Storage Shields Businesses from Energy Price Surges?
The key advantage of battery storage for commercial buildings lies in its ability to protect against fluctuating energy costs. The system provides:
Battery storage shields your business by changing when you buy electricity:
-
Avoid peak tariffs: discharge the battery when grid prices are highest.
-
Increase self-consumption of solar: store excess solar for later on-site use.
-
Reduce reliance on the grid: import less electricity during volatile periods.
-
Support continuity: provide additional resilience if the grid is unstable (design-dependent).
Benefits of Battery Storage for Businesses
Investing in battery storage for commercial buildings creates both immediate and long-term advantages that go beyond simple cost savings.
- Lower energy bills – By storing electricity during cheaper off-peak hours and using it during high-tariff periods, businesses cut their reliance on costly grid energy.
- Greater cost predictability – A commercial battery system helps smooth out exposure to sudden market spikes, making energy budgets easier to forecast.
- Improved sustainability credentials – With commercial solar power battery storage, companies maximise the use of their own renewable generation rather than exporting surplus power at low rates.
- Energy resilience – Stored electricity provides backup power during outages, reducing downtime and protecting critical operations.
- Stronger ESG performance – Demonstrating proactive carbon reduction measures enhances corporate responsibility, strengthens reputation, and meets stakeholder expectations.
Ultimately, combining solar PV (roof-mounted or ground-mounted) with commercial solar power battery storage not only reduces carbon emissions but also provides a financial edge, helping businesses remain competitive in an uncertain energy market.
What Are the Costs and ROI of Battery Storage Systems?
Commercial battery costs vary by site and system size (kW/kWh), grid connection constraints, and whether solar PV is included.
While upfront costs can be significant, the long-term financial benefits are compelling. Savings come from reduced reliance on peak-time grid electricity, better use of on-site renewable generation, and protection against volatile tariffs.
- Payback: often ~5–10 years
- Lifespan: often ~10–15 years
- ROI: improves when you have high peak tariffs, consistent peaks, and/or significant surplus solar to store.
EvoEnergy provides detailed modelling to show the real-world savings a commercial battery system can deliver. This includes forecasting payback times, lifetime savings, and sustainability gains to ensure businesses make an informed investment decision.
Incentives and Support Available in the UK
The UK government has introduced several incentives to encourage adoption of battery storage for commercial buildings:
- Capital Allowances – Enables businesses to offset the cost of installation against taxable profits.
- Smart Export Guarantee (SEG) – Allowing companies with solar PV to earn revenue from exporting surplus energy.
- Grid balancing schemes – Opportunities for businesses with commercial solar power battery storage to provide services to the grid and receive payments.
- Green financing options – Loans and leasing models designed for renewable infrastructure investments.
These mechanisms improve the business case for investing in a commercial battery system, making it accessible for both large enterprises and mid-sized companies.
Is Battery Storage Right for Your Business?
Not every site will have the same needs, which is why assessing suitability is an essential step before investing in battery storage for commercial buildings. The decision will largely depend on how much electricity your organisation uses each day, how exposed you are to high grid tariffs, and whether you already generate renewable energy on-site. Businesses with steady, high demand or those operating during peak tariff hours often benefit most.
If your company has a solar array, commercial solar power battery storage becomes even more attractive, as it allows you to capture and use more of your own low-cost renewable energy. Similarly, organisations committed to sustainability or net-zero goals will find that a commercial battery system strengthens their environmental credentials while improving financial resilience.
EvoEnergy conducts detailed feasibility studies that analyse consumption patterns, building infrastructure, and long-term business goals. This ensures you receive tailored advice on whether battery storage is the right move, and what scale of system would deliver the best returns.
