What is Commercial Battery Storage?

A commercial battery storage system allows businesses to store excess electricity generated from renewable sources like solar panels or wind turbines, or from the grid during off-peak hours for later use, reducing energy costs and improving energy resilience with back up power function.

Adding an EnSmart commercial battery storage system to your business can be a smart investment, see why it’s worth it below:

Lower Electricity Bills - Charge and store enegy at low rates, use at high rates (load shifting).

Reduce Peak Demand Charges - Avoid expensive spikes in energy consumption.

Backup Power - Protect against outages and grid failures

Maximise Solar Energy - Store and use excess solar energy instead of losing it

Revenue Generation - Sell energy back to the grid (if applicable)

Support Sustainability - Improve your company’s green credentials and reduce carbon footprint.

How Commercial Battery Storage Works in Practice?

1. Charging

The battery charges during off-peak hours when electricity is cheaper.

If combined with solar panels, excess solar power is stored instead of being exported to the grid.

2. Energy Storage

The stored electricity is kept in reserve for later use.

The BMS ensures the battery operates efficiently and safely.

3. Discharging (Using the Stored Power)

The battery releases stored energy when:

Electricity prices are higher (peak hours).

There is a power outage.

The business has high energy demand, helping to reduce peak demand charges.

4. Grid Interaction (Optional)

Some businesses sell excess stored energy back to the grid, benefiting from schemes like the Smart Export Guarantee (SEG).

The system can also provide grid balancing services, such as frequency response, earning additional revenue.

How Commercial Battery Storage Maximises Savings?

A commercial battery system helps businesses take advantage of Time-of-Using pricing by:

1. Charging During Off-Peak Hours → The battery stores electricity when prices are lowest.

2. Discharging During Peak Hours → Instead of using expensive grid electricity, the stored energy is used.

3. Reducing Demand Charges → By lowering peak electricity consumption, businesses avoid costly demand charges.

4. Optimising Renewable Energy → If paired with solar panels, excess solar power can be stored for evening use, further reducing reliance on expensive grid power.

Example of TOU Savings

A business operates Monday–Friday, 9 AM – 6 PM, and is on a TOU tariff:

Without Battery Storage:

Consumes 100 kWh during peak hours at £0.30/kWh → £30 per day

With Battery Storage

Charges battery at night at £0.10/kWh

Uses stored power during peak hours instead of grid power

Savings: £20 per day (by avoiding peak rates)

Annual savings: £7,300 (assuming 365 days)

Larger businesses with higher energy usage and demand charges can save even more.
