Summary
Details
- Germany
Requirements can apply to:
Companies exceeding energy-consumption thresholds.
Data center operators.
Public-sector bodies.
Companies generating significant waste heat.
Not every business needs an ISO 50001 or EMAS system.
The 7.5 GWh threshold is central to the corporate management-system requirement, while the 2.5 GWh threshold is relevant to implementation-plan obligations in the circumstances defined by section 9.

What’s Required
1. Energy management for high-energy-consuming companies
Companies with average annual final energy consumption exceeding 7.5 GWh over the previous three completed calendar years must implement either:
An energy management system, such as ISO 50001.
An environmental management system under EMAS.
2. Additional management-system requirements
Covered companies must assess:
Energy inputs and outputs.
Process temperatures.
Waste heat streams.
Recoverable heat.
Technically feasible energy-saving measures.
Economic viability of identified measures.
3. Publish implementation plans
Companies consuming more than 2.5 GWh per year that operate applicable management systems or have completed qualifying energy audits must prepare and publish implementation plans for measures identified as economically viable.
Plans must generally be prepared within three years of identification of the relevant measure.
4. Data center energy management
Applicable data center operators must establish an energy or environmental management system.
Under the current Act, operators were required to have such a system in place by July 1, 2025, subject to the detailed statutory scope.
5. Renewable electricity for data centers
Data centers must source their electricity on an accounting basis from renewable energy at:
At least 50% from January 1, 2024
100% from January 1, 2027
6. Data center efficiency requirements
The Act establishes requirements concerning:
Power Usage Effectiveness.
Waste heat.
Energy monitoring.
Environmental management.
Reporting.
Renewable electricity procurement.
Relevant requirements differ by commissioning date and facility category.
7. Waste heat avoidance and utilization
Covered companies must avoid unnecessary waste heat and use technically unavoidable waste heat where reasonable and feasible.
The Act also establishes a national waste heat platform to improve information exchange between heat producers and potential users.
Important Deadlines
November 13, 2023: Energy Efficiency Act issued.
November 18, 2023: Act entered into force.
July 18, 2025: Original deadline for companies already exceeding the 7.5 GWh threshold when the Act entered into force to implement a management system.
20 months after the threshold is reached: Deadline for companies becoming subject later.
July 1, 2025: Energy or environmental management system deadline for applicable data centers.
January 1, 2027: Data centers must cover 100% of electricity use on an accounting basis with renewable electricity.
2030: Germany targets at least a 26.5% reduction in final energy consumption and 39.3% reduction in primary energy consumption compared with 2008.
Current Status
Active and legally binding.
Germany was also considering amendments in 2026 to accelerate implementation of the revised EU Energy Efficiency Directive and adjust parts of the national framework. The existing EnEfG remains the legal basis unless and until amendments enter into force.
Penalties for Non-Compliance
Violations can lead to administrative fines under the EnEfG.
Potential failures include:
Not establishing the required management system.
Failing to prepare required implementation plans.
Failing to publish plans.
Failing to provide required information.
Data center reporting breaches.
Waste heat disclosure violations.
BAFA conducts sample-based checks of corporate compliance with sections 8 and 9.
Examples of Known Violations / Failure Modes
Incorrectly calculating company-wide energy consumption.
Assuming SME status creates an exemption from the 7.5 GWh rule.
Failing to establish ISO 50001 or EMAS within the required period.
Ignoring economically viable energy-saving measures.
Failing to publish implementation plans.
Missing waste heat information.
Failing to register or report data center information.
Incorrectly calculating renewable electricity coverage.
Treating an energy audit alone as satisfying all EnEfG obligations.
Failing to include all relevant sites in the energy management system.
