EU Energy Efficiency Directive 85 TJ and 10 TJ Enterprise Thresholds

For enterprises with average annual consumption higher than 85 TJ over the previous three years, Article 11 requires an energy management system. The system must be certified by an independent body in line with relevant European or international standards, and Article 11 sets 11 October 2027 as the latest date for having it in place.

For enterprises with average annual consumption higher than 10 TJ over the previous three years that do not implement an energy management system, Article 11 requires an energy audit. The first audit is due by 11 October 2026, and subsequent audits must be carried out at least every four years.

A threshold file should show the enterprise boundary used, the three years included, the final-energy inputs counted, the conversion basis used to express consumption in TJ, and the final average. Article 11 itself supports the three-year and all-energy-carrier elements but does not provide a group-consolidation method. Commission Recommendation (EU) 2024/2002, which is guidance rather than binding law, suggests counting linked enterprises under more-than-50% control across the EU while not counting partner enterprises. National transposition or authority guidance controls the operative method.

Article 11 also creates a separate authority-information trigger. Where an enterprise covered by paragraph 1 has annual consumption above 85 TJ in a given year, or an enterprise covered by paragraph 2 has annual consumption above 10 TJ in a given year, Member States must ensure that this information is made available to the national authorities responsible for implementation.

Threshold status can change. The Commission Recommendation suggests one year for a later entrant to complete an audit and two years for a later entrant to introduce an EMS. Its examples also say that an enterprise crossing 10 TJ in year n still completes the audit by year n+1 even if the rolling average then falls below 10 TJ, while an enterprise that moves from above 85 TJ to below 85 TJ before its EMS deadline shifts to the audit route if it remains above 10 TJ. These are Commission interpretations; national law sets the enforceable deadline and transition treatment.

The 85 TJ path is not satisfied by an informal efficiency programme. Article 11 requires an energy management system certified by an independent body according to relevant European or international standards.

The 10 TJ path applies when the enterprise's average annual consumption is higher than 10 TJ and it does not implement an energy management system. The audit must be independent and cost-effective through qualified or accredited experts, or implemented and supervised by independent authorities under national law.

Article 11 requires the enterprise concerned to draw up a concrete and feasible action plan from the energy audit recommendations. The action plan must identify measures to implement each audit recommendation where technically or economically feasible and must be submitted to enterprise management.

Member States must ensure that the action plans and the recommendation implementation rate are published in the enterprise's annual report and made publicly available, subject to Union and national rules protecting trade secrets, business secrets, and confidentiality.

Annex VI sets the minimum criteria for energy audits, including audits carried out as part of energy management systems. Those criteria are the practical checklist for whether an audit record is strong enough to support the Article 11 threshold path.

The audit should be based on up-to-date, measured, traceable operational data; review the energy-consumption profile of buildings, industrial or commercial operations or installations, and transport; identify energy-efficiency measures; identify cost-effective renewable-energy use or production potential; and provide detailed validated calculations for proposed measures.
