Energy-efficient production

Optimizing energy use, reducing CO₂ emissions: With energy-efficient production, industry can contribute a great deal to a sustainable reduction in CO₂ emissions without limiting productivity – in fact, quite the opposite.
Energy and industry

Energy efficiency as a contributor to success

Climate protection, efficient use of resources, rising energy costs, new supply models, and strict environmental regulations: For all these goals, energy is a decisive competitive factor, whatever the industry. There is therefore no alternative to increasing energy efficiency. A great challenge – but also a great opportunity. Because by making plants more energy-efficient, companies can also achieve considerable cost savings.

Energy efficiency in production – in reality

Energy-efficient production means more than simply reducing energy consumption, CO₂ emissions, or costs – it also involves linking energy and production data in order to analyze and optimize not only energy consumption but also the energy productivity of machines, plants, and processes. These measures provide the opportunity to achieve all-round improvements in process productivity and efficiency.

Transparent visualization of energy data

The question:

Do two similar machines consume different amounts of energy?

 

The answer:

Measuring devices are installed on both machines to record and evaluate the consumption data. The analysis shows that machine A requires more energy for vacuum operation and the conveyor belt requires more electrical energy.

 

The solution for greater efficiency:

A leakage in the vacuum system is identified and repaired. A motor with a defective bearing is identified on the conveyor belt, and it is replaced with a more efficient motor during its next maintenance.

Assessing and analyzing the energy efficiency of machines

The question:

I would like to purchase a new machine. How can I compare the consumption performance of the machines on offer and reduce energy consumption that does not contribute to added value?

 

The answer:

Using an appropriate solution, energy consumption can be ascribed to the individual energy operating states (off, standby, ready for operation, in operation) and evaluated and compared accordingly.

 

The solution for greater efficiency:

Machine suppliers can provide their customers with an energy consumption profile (standardized acceptance form) during the purchasing phase. Actual energy consumption on-site can be analyzed by means of a reference measurement. Using key energy performance indicators (EnPI) and benchmarks, all machines can be evaluated continuously and comprehensively and appropriate optimization measures can be implemented, e.g., adaptation of the standby mode.

Meeting requirements, identifying savings potential, optimizing contracts

The question:

How can I identify the savings potential in my operations, optimize my contract with the energy supplier, reduce my tax payments, and benefit from state subsidies?

 

The answer:

Introduce a certified energy data management system in production that reports and archives energy data in accordance with legal requirements (e.g., ISO 50001, German Renewable Energy Act).

 

The solution for greater efficiency:

Identifying the major energy consumers allows you to avoid energy peaks. An automated load management system can automatically shut down systems and make them available again. Forecasting the expected load profile enables you to negotiate an optimized contract with the energy supply company. Transparent energy consumption helps make personnel more aware of energy efficiency within the company, and energy efficiency measures and targets such as the annual increase in energy efficiency can be tracked and verified.

Why energy has such an enormous potential

On average, energy costs account for up to 10% of all production costs. In energy-intensive industries, the percentage can even get up to 40%. Yet it is possible to transform energy into a genuine added value: you can achieve savings of as much as 30% or more with our innovative drive technology, for example. We are making a decisive contribution to realizing energy-efficient production – worldwide.
