The battery supplements power. It does not create energy.
Illustrative example, not a Bergheimer Power reference: the site needs 700 kW. The grid connection provides 500 kW and the battery supplies 200 kW.
The duration of the requirement is decisive. An additional 200 kW for 15 minutes represents 50 kWh of energy; for two hours it is already 400 kWh. The actual design also takes losses, reserves and technical limits into account.
When can the solution make sense?
Especially when you need additional power for short periods or repeatedly during a production cycle, when expanding an operation or while charging vehicles. The battery must have room to recharge between individual requirements.
If you need higher power continuously, storage alone may not be a suitable alternative to upgrading the infrastructure.
We also compare other options.
We assess a grid connection upgrade, load management, a battery and combinations of these. Shifting part of the non-critical demand can reduce the power the storage needs.
BESS can also be an interim solution. In that case we evaluate what role it will play after a later grid upgrade, for example using photovoltaics or reducing peaks.
The value is not necessarily only on the electricity invoice.
If the solution allows a production line or a charging site to start earlier, additional production, a new contract or postponing another investment can also matter. We keep these benefits separate from direct energy savings.
