Storage for peak shaving
In peak shaving, the storage system delivers energy exactly when the business briefly needs high power. This reduces the maximum power drawn from the grid.
In peak shaving, the storage system delivers energy exactly when the business briefly needs high power. This reduces the maximum power drawn from the grid.
The starting problem
Load peaks arise from machine starts, refrigeration, compressors, pumps, charging points, drying or simultaneous loads. They can drive up demand charges or overload grid connections.
How a storage system can help
The EMS monitors grid consumption. When the business exceeds a threshold, the storage system discharges and reduces the power drawn from the grid. For peak shaving, kW often matters more than kWh.
Key planning factors
- maximum peak power
- desired grid demand threshold
- duration and frequency of the peaks
- charging window between peaks
- demand charge
- storage power
- EMS control speed

Frequently asked questions
What does peak shaving with a battery storage system mean?
In peak shaving, the storage system delivers energy exactly when the business briefly needs high power. This reduces the maximum power drawn from the grid.
How does peak shaving work technically?
The EMS monitors grid consumption. When the business exceeds a threshold, the storage system discharges and reduces the power drawn from the grid. For peak shaving, kW often matters more than kWh.
Which planning factors matter?
Maximum peak power, the desired grid demand threshold, duration and frequency of the peaks, the charging window between peaks, the demand charge, the storage power and the EMS control speed.
When does peak shaving not work well?
When load peaks are long or very frequent — the charging window between peaks is then too short to recharge — or when the site demand charge is too low to carry the investment.
