Peak Shaving with Battery Storage: Cap Load Peaks, Cut Grid Fees
How businesses use battery storage to reduce expensive load peaks, lower grid fees and unlock additional revenue – the basics explained clearly.
For many businesses, short-term load peaks are an expensive cost driver: the demand charge in the grid fee is often based on the highest power measured during the billing period. A battery storage system can counteract this in a targeted way.
What peak shaving means
With peak shaving, the storage system covers short-term load peaks instead of drawing them from the grid. The measured peak power drops – and with it the demand charge. The effect is predictable and lasts across the entire lifetime of the system.
More than just cost reduction
A battery storage system typically does several things at once:
- Cap load peaks and thereby reduce grid fees
- Increase self-consumption by buffering surplus solar power
- Generate additional revenue through participation in ancillary and intraday markets
Which benefit takes priority depends on the load profile and generation. What matters is sizing that fits the specific operation.
When storage pays off
Profitability depends on storage size, the reducible load peak, the demand charge and possible trading revenues. Our battery storage calculator gives you a first impression – instantly and without obligation.
For a robust design, we analyse your load profile and size the storage to be both grid-supportive and economical.
