Overview
The EnEfG represents Germany’s first cross-sector legal framework dedicated specifically to energy efficiency. Its primary objective is to reduce overall energy consumption while strengthening energy security and contributing to climate mitigation. The law applies across multiple sectors, including industry, public administration, data centres, and other energy-intensive activities. It establishes national energy-saving targets for 2030 and outlines a longer-term trajectory toward 2045. A key feature of the Act is the shift from voluntary efficiency measures to legally binding obligations. It requires both public authorities and private sector entities to actively manage and reduce energy use, embedding efficiency considerations into operational and investment decisions.
Reporting requirements
Obligations for companies are based on energy consumption thresholds:
>7.5 GWh/year: Mandatory implementation of energy or environmental management systems (e.g. ISO 50001 or EMAS)
>2.5 GWh/year: Requirement to identify, document, and publish economically viable energy efficiency measures
All affected companies must address waste heat recovery and reporting
These requirements apply to both large companies and, for the first time, energy-intensive SMEs.
Data centre provisions
The Act introduces specific rules for data centres, including:
Minimum energy efficiency standards
Obligations to use and reuse waste heat
Requirements related to energy sourcing and operational efficiency
Penalties for non-compliance
The EnEfG establishes a system of administrative fines to enforce compliance with its requirements. Companies that fail to meet key obligations stated above may face penalties of up to €100,000, particularly where companies do not implement required systems or fail to comply fully or on time. Compliance is monitored by authorities such as the Federal Office for Economic Affairs and Export Control (BAFA), which conducts checks, including on a random basis, and can initiate enforcement actions.
Current status
The EnEfG entered into force in November 2023. Implementation is ongoing, with obligations phased in from 2024 onwards. Public sector energy-saving requirements and company compliance measures are being introduced progressively, with enforcement overseen by authorities such as the Federal Office for Economic Affairs and Export Control (BAFA). The Act is also expected to evolve further as Germany continues aligning national legislation with updates to the EU Energy Efficiency Directive.
