How Battery Energy Storage Systems Reduce Business Energy Costs

What Are Battery Energy Storage Systems?

How Does Battery Storage Help Reduce Energy Costs?

Many businesses assume reducing energy costs simply means using less electricity. However, when your business uses electricity can be just as important.

Electricity prices often vary throughout the day, and businesses can also incur additional demand charges when large amounts of power are drawn from the grid over a short period.

Battery storage helps address these challenges by allowing businesses to:

• • • Reduce electricity costs by using stored lower-cost energy during peak tariff periods.
    • Reduce expensive demand charges by lowering peak electricity demand.
    • Optimise energy usage throughout the day.
    • Improve long-term control over energy expenditure.

Rather than relying solely on grid electricity during peak demand, businesses can use stored energy to reduce operating costs and improve efficiency.

What Is Peak Shaving and Load Shifting?

You may have heard the terms peak shaving and load shifting, but what do they mean? Put simply, these are the strategies that help businesses make better use of their energy.

Peak shaving reduces the amount of electricity your business draws from the grid during periods of highest demand. Instead, stored battery power is used, helping reduce demand charges.

Load shifting involves charging the battery when electricity is cheaper, such as overnight, and using that stored energy later when tariffs are higher.

These strategies happen automatically once a correctly designed battery storage system is in place, helping businesses reduce costs without disrupting day-to-day operations.

Does Battery Storage Only Work with Solar?

One of the biggest misconceptions surrounding battery storage is that it only delivers value when combined with solar panels.

Many commercial battery storage projects are installed without solar because they provide a range of practical business benefits.

Standalone battery storage can help businesses:

• Reduce electricity costs through tariff optimisation.
• Reduce peak-demand charges.
• Support EV charging infrastructure without major electrical supply upgrades.
• Provide backup power for critical systems during unexpected power interruptions.
• Improve operational resilience by giving businesses greater control over their energy supply.

For many organisations, these benefits alone provide a compelling business case for battery storage.

How Can You Get More from Your Solar Investment?

If your business already has solar PV, battery storage can help you get even more from your investment.

Without battery storage, surplus electricity generated during the day is often exported to the grid, only for businesses to buy electricity back later when demand remains high.

Battery storage stores that excess energy for use later, helping businesses:

• Increase self-consumption of renewable energy.
• Reduce reliance on imported electricity.
• Improve the return on investment from their solar PV system.
• Lower long-term energy costs.

Instead of exporting valuable renewable energy, businesses can use more of the electricity they generate themselves.

 Is Battery Storage Right for Your Business?

Battery storage can benefit a wide range of commercial and industrial environments, including:

• Manufacturing facilities.
• Warehouses and distribution centres.
• Commercial offices.
• Retail premises.
• Businesses introducing EV charging infrastructure.
• High-energy-use industrial sites.

Every organisation has different energy demands, which is why selecting the right solution starts with understanding how your site uses electricity today and how those requirements may change in the future.
