EU Energy Efficiency Directive Article 11 Threshold calculation for 85 TJ and 10 TJ enterprise scope

Calculate the threshold at enterprise level using average annual final energy consumption for the three completed years before the assessment year: n-3, n-2, and n-1. Article 11 says to take all energy carriers together, so the record cannot cover only electricity, gas, one site, or one business unit when the applicable enterprise boundary is broader.

Commission Recommendation (EU) 2024/2002 suggests using invoiced energy, energy delivered through energy service providers, and self-consumed renewable energy inside the system boundary. Exported renewable energy is subtracted if it has not already been netted out. A Member State may allow self-consumed renewable energy other than bioenergy to be excluded, so that point needs a national check.

If the enterprise is above 85 TJ, Article 11 points to an independently certified energy management system. If it is above 10 TJ and does not implement an energy management system, Article 11 points to an energy audit obligation. The 10 TJ test is not a smaller version of the 85 TJ duty; it is the audit threshold for enterprises that do not have an energy management system.

The 85 TJ threshold is the higher-consumption trigger. Article 11 requires Member States to ensure that enterprises above that average annual consumption implement an energy management system, certified by an independent body in accordance with relevant European or international standards.

The 10 TJ threshold applies to enterprises with average annual consumption above 10 TJ over the previous three years that do not implement an energy management system. Those enterprises are subject to energy audits. Article 11 also states that the first audit for the covered enterprises is due by 11 October 2026 and subsequent audits are at least every four years, while the energy management system for the 85 TJ group is to be in place by 11 October 2027.

Keep the calculation pack with the source data. A reviewer should be able to see the enterprise and linked-enterprise boundary, the three completed annual totals, every included carrier and use, renewable generation and export treatment, conversions to TJ, and the conclusion for both thresholds.

The Commission recommends considering all linked enterprises within EU territory and, for complex structures, suggests counting linked enterprises under more than 50% control but not partner enterprises. This is guidance, not a definition added to the Directive, so record the Member State rule actually applied. Annex VI's audit-data criteria apply to the audit itself, not automatically to the threshold calculation.

Directive (EU) 2023/1791 sets the EU-level Article 11 framework, but enterprises should check the Member State rules that transpose it. National law and authority guidance can affect the reporting channel, evidence format, audit supervision route, enforcement process, and how the enterprise boundary is handled in practice.

Do not add penalties, exemptions, or local filing dates to a threshold conclusion unless they come from the relevant national source. For this FAQ, the cited EU answer is limited to the 85 TJ and 10 TJ Article 11 tests, previous-three-year averaging, all energy carriers together, the audit and energy-management-system consequences, and the need to retain traceable records.
