Experten Konfiguration

Reduction of the supply power

The KBR solution:

multimax D6

KBR energy optimization works in the background without affecting the production process. Thanks to the optimized trending process, the system detects a potential power peak at an early stage and regulates the power with the connected loads. multimax can be used regardless of industry and company size.


Time control of consumers

The KBR solution:

multimax D6 and multimax IGW

The electroplating baths are connected via the time programs of a multimax IGW. Accordingly, the required baths are heated up before work begins, depending on the production process. In the high heating phase, the baths are optimized so that no unnecessary power peaks occur. Even during working hours, multimax ensures that the set maximum value is not exceeded.


Minimize switching operations

The KBR solution:

multimax D6 and multimax D4

Instead of a rigid “load on the grid” feedback signal, multimess D4 measuring modules are used to measure the current power and report it back to multimax. This means that the energy optimization works with the power actually consumed at the moment. This system can significantly reduce the number of switching operations.

Mobile Auswertung

Atypical grid usage (§ 19 NEV)

The KBR solution:

multimax D6

The target value in the high load window only has to be maintained for three months of the year. This is achieved with the help of multimax time programs, which are programmed to customer specifications. Once the high-load window for the following year has been announced, this can be defined in parallel for the active program. Activation takes place automatically at the turn of the year.

Example calculation for atypical grid usage per year:*


Maximum output regular 699 kW

savings potential:

20945 €

Performance price:

84.66 €/kW
Regular grid fee: 699 kW x 84.66 €/kW = 59177 €

The multimax time programs control the maximum output in high-load operation. The future grid fee will be significantly reduced:

Maximum output in the high load window: 451.6 kW

KBR recommendation:

Performance in the high-performance window with multimax D6
further decreasing and increase the savings effect.

Power price: 84.66 €/kW
Future grid fee: 451.6 kW x 84.66 €/kW = 38232 €

*Calculation based on values recorded in a medium-sized electroplating company. Status: 2020.


Individual grid fee (Section 19 NEV)

The KBR solution:

multimax D6

The reference power is minimally reduced with the help of multimax. As a result, the number of hours of use can be increased to over 7,000 hours. With a view to the enormous savings of over 100,000 euros per year, the energy optimization system is set up redundantly. If one system were to fail, the redundant device takes over without delay.

Example calculation for individual grid fee per year: *

Peak power: 1495 kW Potential savings:
Grid fee to date:
1495 kW x 92.70 EUR/kW/a
= 138,587 €
Consumption: 0.4 GWh
Hours of use: 6957 h

The multimax energy optimization reduces the power peak to 1450 kW. This results in the following hours of use:

Maximum output in the high load window: 451.6 kW

New grid fee:
1450 kW x 92.70 EUR/kW/a x 0.20**
= 26,883 €

111,704 €

Power price: 84.66 €/kW
Future grid fee: 451.6 kW x 84.66 €/kW = 38232 €

*The prerequisites for individual grid charges in the above case study: the total active energy per year is at least 10 GWh and the hours of use are at least 7,000 hours.

**20% minimum share of grid usage fee
