Implement the ResMa® energy management system by 18 July 2025 - act now before the deadline passes

Energy Efficiency Act

Fulfil the requirements of the Energy Efficiency Act (EnEfG) with our ResMa® energy management system

When the Energy Efficiency Act (EnEfG ) came into force on 18 November 2023, the requirements of the Energy Services Act (EDL-G) for companies were extended. Among other things, the obligation to set up energy management systems (EMS) or environmental management systems (EMS) was introduced for companies. Regardless of SME status, it applies to companies that have an average total energy consumption of more than 7.5 gigawatt hours (GWh)per year in the last three calendar years.

Overview § 8 Energy Efficiency Act (EnEfG)

Important changes for companies in Germany in 2025

Do you exceed the limit of 7.5 GWh per year? Then urgent action is required.

According to Section 8 of the Energy Efficiency Act (EnEfG), all companies - regardless of whether they are SMEs or non-SMEs - must introduce a certified energy management system (EMS) as soon as they exceed a total annual energy consumption of more than 7.5 GWh for the first time. The deadline for implementation is already running: By 18 July 2025 at the latest, companies that are subject to the regulation must have set up a corresponding system. Companies with high energy consumption must also develop implementation plans for energy efficiency measures that meet certain standards and norms in order to improve their energy efficiency in accordance with Section §9 of the EnEfG.

What are the targets of the EnEfG?

The EnEfG has several targets that are to be achieved by increasing energy efficiency. These include reducing final energy consumption, increasing energy efficiency in businesses and public bodies, promoting the use of renewable energies and improving the environmental balance.

What are the benefits of introducing an energy management system?

Energy management in accordance with DIN EN ISO 50001In addition to fulfilling the legal requirements, the introduction of an energy management system offers the following advantages:

  • Reduction in energy costs
  • Strengthening the company image
  • More environmentally conscious design of the company.

What are the consequences of non-compliance?

A breach of the obligations under the EnEfG may be punished with a fine of up to €100,000. Fact sheet on the legal provisions of BAFA
