Fulfill EnEfG obligations
Report waste heat, create implementation plans and introduce energy monitoring – we support you!
Companies with an energy consumption exceeding 2.5 GWh are required to record and report their waste heat in compliance with the Energy Efficiency Act (EnEfG). For higher consumption levels, plans for final energy savings and monitoring systems are also mandatory.
Our experts will guide you through all the necessary steps.

FAQs
In addition to companies, the Energy Efficiency Act also obliges public bodies and data centers to reduce their final energy consumption.
All companies - including SMEs - with a final energy consumption of more than 2.5 GWh are affected by the regulations of the Energy Efficiency Act.
According to the EnEfG, all companies with a final energy consumption of more than 7.5 GWh must introduce either an energy management system in accordance with DIN EN ISO 50001 or an environmental management system in accordance with EMAS.
According to the Energy Efficiency Act, energy or environmental management systems must also record energy flows and process temperatures.
According to the EnEfG, implementation plans must be drawn up, reviewed and published within 3 years.
The audit must be carried out by an independent expert (e.g. energy auditor in accordance with EDL-G) who has not drawn up the plans themselves.
Waste heat must be reported annually on the waste heat platform by 31 March. However, for the first time on 1 January 2025.
