Grid charge optimization

Do you have a manufacturing business, an industrial company with high peak loads, an energy-intensive business or are you active in a municipal facility? Then our battery storage systems will help you keep your grid charges as low as possible.

Enormous reduction in energy costs and avoidance of expensive grid expansion

No interference with established processes and production

Promotion of grid stability

Integration into existing load management

Three methods


The electricity price for energy-intensive companies (> 100,000 kWh consumption per year) is made up of the energy price and the demand charge. The demand charge, in turn, is directly related to peak loads, i.e., particularly powerful spikes in power consumption that occur when you temporarily need more power than usual during a particular phase. This is because the demand charge is always calculated in proportion to the highest load peak that occurs. With intelligent battery storage, you can reduce these unnecessary and often enormously high electricity costs: The battery storage caps the load peaks above a certain value and serves the energy demand above that with the energy stored in the battery storage. So as soon as a certain power threshold is exceeded, the battery storage system supplies your company with energy and thus keeps your demand charge low.


In Germany, the energy suppliers determine the high-load time window every year. If you avoid load peaks during this period, carry out your production in a way that serves the grid and thus relieves the grid, the grid provider rewards you with a lower grid fee. Various requirements must be met for this atypical use of the grid (Section 19 (2) Sentence 1 StromNEV), and the use of a battery storage system gives you this flexibility in electricity consumption and production.


If you have intensive grid usage with at least 7,000 full-use hours as well as 10 GWh annual consumption, then you can reduce your energy costs by applying for an individual grid fee (as per § 19 para. 2 p. 2 StromNEV). Since these values are rarely reached, the battery storage comes into play: This allows for a consistent load profile so that the 7,000 full-use hour limit can be exceeded.

Compared to conventional generation plants, commercial storage systems offer the benefit of postponing but not reducing the amount of electricity purchased. On the other hand, in the case of standby gensets, the required energy is generated and the total amount of electricity drawn from the grid is reduced, as are the hours of full use.

What now?

Let us know your load profile: The load profile is the recording of the power consumed by a point of consumption over a certain period of time. The decisive factor is a data interval of 15 minutes and the specification of the power values in kW. These data are the basis for a meaningful analysis.

We will take care of your load profile and will be happy to help you obtain it from your grid operator. With your permission, we will obtain all the information we need.
