France industrial energy audits and energy-management thresholds

The official French thresholds for four-year energy audits and certified energy-management systems, with an industrial action checklist.

01
Status

Check the legal status

What you need to know: Check the enterprise's average annual final-energy use against 2.75 GWh and 23.6 GWh. The applicable route depends on the threshold and whether a qualifying management system is in place.

Change

What changed

Current French guidance sets a four-year energy-audit duty from 2.75 GWh average annual final-energy consumption where an exempting energy-management system is not in place, and certified energy management from 23.6 GWh.

Inzonex removable modular insulation on industrial equipment
Equipment heat loss

Measure exposed hot surfaces

Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.

  • Design target: surface temperature at or below 45 °C, subject to the application and design review
  • Claimed heat-loss reduction: up to 96%, subject to the measured boundary and insulation specification
  • Removable construction for inspection and maintenance access
  • Calculation record available for the selected equipment and operating conditions

Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.

03
Scope

Check if this affects you

Enterprises whose average annual final-energy consumption reaches the French audit or energy-management thresholds.

04
Timing

Dates and sequence

The chart separates publication dates, effective dates and actions. It does not treat a proposal as law.

  1. Maintain the energy-consumption boundary and evidence
  2. Repeat the energy audit where the audit duty applies
  3. Check the certified energy-management requirement
05
Assessment

Risks and potential

These are implementation consequences from the cited rule. Any financial result still needs measured inputs.

Risk

Using a single site's bill, the wrong organisational boundary or a single year can give the wrong threshold result.

Potential

Use the audit to create a measured project register. For heat-loss work, calculate annual useful energy saved from measured surface conditions and operating hours, then convert this to fuel, cost and CO2 with stated factors.

No assumed saving percentage. Use measured activity data, a stated factor and the applicable carbon price.
06
Action

What you need to do

  1. Calculate the applicable multi-year average using the official boundary.
  2. Decide whether the audit route or a certified energy-management system is the operative requirement.
  3. Build an implementation register that connects significant energy uses to measured projects and savings evidence.
