Peak Shaving Explained: How Businesses Reduce Electricity Bills
What Is Peak Shaving?
Peak shaving is one of the most effective ways businesses can lower electricity costs using battery storage systems. The strategy involves reducing the amount of electricity drawn from the grid during peak demand periods.
When electricity demand is high, suppliers charge significantly higher rates. A Battery Energy Storage System (BESS) allows businesses to use stored electricity instead.
Why Peak Demand Charges Matter
Many commercial electricity tariffs include demand charges, which are based on the highest level of electricity consumption during a billing period.
Even a single short period of high energy usage can increase monthly bills.
Peak shaving helps businesses:
Reduce maximum demand
Lower electricity tariffs
Stabilise energy costs
How Battery Storage Enables Peak Shaving
A commercial battery system stores electricity during off-peak hours when prices are lower.
When demand rises, the battery automatically discharges stored energy instead of drawing power from the grid.
This results in:
Reduced peak load
Lower demand charges
More predictable electricity costs
Industries That Benefit Most from Peak Shaving
Peak shaving is especially beneficial for businesses with high or fluctuating electricity demand.
Common sectors include:
Supermarkets
Manufacturing
Logistics centres
EV charging hubs
Industrial refrigeration facilities
These industries often operate large equipment that causes sudden spikes in energy consumption.
Combining Peak Shaving with Solar Energy
Businesses with solar installations can maximise their investment by integrating battery storage.
Solar energy generated during the day can be stored and used during the evening peak demand period.
This strategy increases energy self-consumption and further reduces electricity costs.
Peak shaving is one of the most powerful tools available for businesses looking to reduce electricity bills and improve energy efficiency.
By integrating Battery Energy Storage Systems, organisations can gain control over their energy usage and significantly lower their operating costs.
