# EED Article 11 corporate group and site aggregation FAQ

How to calculate EU Energy Efficiency Directive Article 11 enterprise thresholds across sites, energy carriers, and national transposition rules.

*FAQ* *Article 11* *EU EED*

## EED Article 11 Corporate group and site aggregation

Article 11 of Directive (EU) 2023/1791 uses enterprise energy consumption, not employee count, as the trigger for mandatory energy management systems and energy audits.

For multi-site or group structures, calculate the grounded EU threshold first, then check the Member State transposition rule that applies to the legal entity and sites.

Under Article 11 of the EU Energy Efficiency Directive, the core calculation is the enterprise's average annual energy consumption over the previous three years, taking all energy carriers together. The directive sets EU-level thresholds for energy management systems and energy audits, while Member States transpose and administer the details in national law.

## Does EED Article 11 require corporate group aggregation?

Article 11 speaks in terms of "enterprises" with average annual energy consumption above specified thresholds. The grounded EU text does not create a universal standalone rule that says every parent company must automatically aggregate all subsidiaries as one group for Article 11 threshold testing.

A corporate group should therefore separate two questions: first, which enterprise is being tested under the EU threshold wording; second, whether the relevant Member State's transposition, reporting platform, guidance, or authority practice requires aggregation across local entities, branches, establishments, or controlled sites. Do not rely on a group-wide spreadsheet alone unless it can also be reconciled to the national legal entity or site boundary that the authority expects.

- Use the EU directive threshold as the baseline: average annual energy consumption of the enterprise over the previous three years.
- Include all energy carriers together when calculating the threshold, not only electricity or fuel bought by one facility team.
- Check national transposition before deciding whether separate group companies, branches, leased facilities, or managed sites must be combined for local compliance.
- Keep a boundary memo only if it identifies the legal entities, sites, meters, carriers, exclusions, and national rule used for the calculation.

- [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Supports the national-transposition caveat and the Commission's Article 11 guidance context for energy management systems and energy audits.

## How should the Article 11 threshold calculation work across sites?

Start with the enterprise boundary required by the applicable national rule, then gather consumption for every site inside that boundary for each of the previous three years. The calculation should cover all energy carriers together, so electricity, gas, district heating or cooling, fuels, and other carrier data should not be screened separately unless the national template requires a separate presentation before aggregation.

If the three-year average is higher than 85 TJ, Article 11 points to a certified energy management system. If it is higher than 10 TJ and the enterprise does not implement an energy management system, Article 11 points to an energy audit obligation. The site list is evidence for the enterprise calculation; it does not supersede the enterprise-level threshold test.

- Define the tested enterprise and the Member State rule used for that definition.
- List each included site, facility, branch, leased site, and operational unit in the tested boundary.
- Collect measured consumption by year and by energy carrier, then convert into a common unit before calculating the three-year average.
- Reconcile the final average to the 85 TJ energy management system threshold and the 10 TJ energy audit threshold.
- Flag missing meters, shared landlord supplies, estimated consumption, acquisitions, disposals, and partial-year operations because they can change the boundary evidence.

- [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Supports the Article 11 threshold calculation and the obligation split between certified energy management systems and energy audits.
- [Commission Recommendation (EU) 2024/2002 on Article 11 energy management systems and energy audits](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32024H2002&qid=1719245800368&ref=sorena.io) - The Commission identifies this recommendation as Article 11 guidance for interpreting energy management system and energy audit provisions.

## What evidence should support a group or site aggregation answer?

Evidence should prove the threshold calculation and the boundary choice. A useful file shows which enterprise was tested, which sites were included, which energy carriers were counted, which three years were used, and how the result maps to the Article 11 obligation.

For audit readiness, the underlying energy data should also be traceable enough to support an energy audit. Annex VI requires energy audits to use up-to-date, measured, traceable operational data and to review the consumption profile of buildings or groups of buildings, industrial operations or installations, including transportation.

- Legal-entity and site register for the tested enterprise boundary.
- Three-year annual consumption table by site, carrier, source meter or invoice system, and conversion factor.
- Record of included and excluded sites, including landlord-supplied energy, temporary sites, acquisitions, disposals, and closed facilities.
- National transposition source or authority guidance used for any group, branch, establishment, or site aggregation decision.
- Management-system certificate, energy audit report, or action-plan record, depending on which Article 11 obligation is triggered.

- [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Supports the point that the directive expands audit obligations to companies above an energy-consumption threshold regardless of size.

## What national-transposition caveats matter most?

Article 11 is an EU directive obligation implemented by Member States, so national law can determine the authority, reporting route, templates, platform, verification process, and practical treatment of local corporate structures. The EU directive also requires Member States to make threshold information available to national authorities for enterprises above the Article 11 consumption levels.

The main compliance risk is treating the EU threshold as if it answers every local boundary question. For a multinational group, repeat the calculation for each Member State where national law may apply, using the local entity and site boundary required there. Where national law is unclear, document the uncertainty and seek confirmation from the competent authority or a qualified local adviser before reporting or publishing the answer.

- Do not import an old large-enterprise employee-count test into the recast Article 11 threshold analysis.
- Do not exclude non-electricity carriers from the threshold calculation unless the applicable national rule expressly supports the treatment.
- Do not assume a parent-level aggregation rule, a single-site rule, or a legal-entity-only rule without checking the Member State implementation.
- Do not cite penalties, filing deadlines, or enforcement mechanics unless they come from the relevant national transposition source.
