France CEE IND-UT-134: industrial energy-performance measurement

IND-UT-134 is a standardised operation in France's certificats d'économies d'énergie (CEE) scheme. Version A35-2 covers the installation of a system that measures energy performance indicators, or indicateurs de performance énergétique (IPE), for eligible industrial equipment or groups of equipment.

The Ministry's current operation-sheet catalogue still identifies A35-2 as the applicable technical sheet. A revised Part A declaration form applies from 1 July 2026, but it remains tied to A35-2. The form records the operation and its cost; it does not replace the technical requirements in the operation sheet.

This is a funding and evidence framework. It is not a general legal requirement for every industrial monitoring project, and a working dashboard does not establish that a CEE claim is eligible.

Eligible industrial uses and the strict power limit

The sector is industry. The measurement system must cover one or more items of equipment that together constitute one of the named energy uses:

• production or distribution of heat;
• production or distribution of compressed air;
• production or distribution of cooling;
• a thermal or electrical industrial process; or
• another motor-driven system, such as pumps, grinders, fans or conveyors.

Emergency equipment is excluded. The nominal power of each measured item or equipment group must be strictly below 10 MW. Exactly 10 MW is not eligible: the current control rules classify an operation as unsatisfactory where the relevant nominal power is greater than or equal to 10 MW.

For a group, use the sum of the nominal powers of the instrumented equipment. Use nameplate power or, where it is unavailable, a manufacturer document. For thermodynamic equipment, use nominal electrical power.

One item of equipment cannot normally support several CEE applications under this operation. The exception is equipment that uses several forms of energy at the same time. In that case, the operation may be used separately for each energy only if the sum of the nominal powers used across the applications does not exceed the nominal power of the complete installation.

The IPE pairs energy with production or service

An eligible IPE is not an energy total alone. A35-2 defines it as a function of two measurements over the same period:

1. energy consumed by the equipment or equipment group; and
2. production or the level of service delivered by that equipment or group.

The sheet names minimum indicators by use:

The label rendement is retained from the official sheet. For a process, the stated kWh per production unit behaves as an energy-intensity indicator: a higher result represents more energy per unit, rather than a higher conversion efficiency. Define the formula, sign, unit, time boundary and treatment of rejected or reworked production before the system is commissioned.

The energy and output boundaries must match. Do not divide the electricity for an entire compressed-air station by output from one compressor, or compare boiler fuel over one shift with heat output over a calendar day. The equipment performance measurement-boundary guide shows how to keep input, useful output and service on the same boundary.

Complete the study before committing the operation

Before the operation is committed, a professional or design office must complete a study for integrating the measurement system at the site. The study identifies the energy uses and the equipment within each use. It describes:

• the measurement system for each use;
• the relevant performance indicators;
• existing and new measurement equipment; and
• how collected data will be used and presented.

It must cover at least steps 1 to 6 of the measurement and monitoring plan in NF EN 17267. Treat this study as the controlled design basis. The commercial quotation, point schedule and software specification should use the same equipment identities, boundaries, indicators and intervals.

Existing system elements can be used where their operation and compatibility with the new elements have been checked. New measuring devices and means of collection and historisation must be acquired by the beneficiary. The energy-management software must be bought, rented or supplied by subscription. A conventional office spreadsheet is not an eligible energy-management software package under the sheet.

Installation must be carried out by a professional. If the beneficiary's internal technical team carries out the work, the professional supplying the measuring equipment or software must attest the correct operation of the system and the compatibility of the equipment.

Ten-minute collection and the one-day exception

The normal rule is a collection interval of no more than ten minutes for the energy-consumption and production data used to construct the IPE.

There is one narrow exception. For the use called “thermal or electrical industrial process”, the collection interval for the production unit may be extended to no more than one day. This does not create a general daily-data route for compressed air, cooling, heat systems or other motor-driven systems.

Specify the measurement chain behind the interval rather than only the reporting rate. For every input, record:

• the physical quantity and unit;
• the source instrument and equipment identity;
• the raw sample or meter-update interval;
• the collection and aggregation interval;
• timestamp source and time zone;
• scaling, sign and rollover treatment; and
• quality state for missing, stale, substituted or invalid values.

A ten-minute database row is not proof of a ten-minute measurement. Repeating a slow instrument value, estimating production after the fact or filling gaps with zero can create a complete-looking series that does not meet the intended measurement boundary.

Rolling-year access, retained history and alarms

The system must communicate results to the user, not merely store raw readings. A35-2 requires at least:

• display of the IPE for the interval between two result points;
• access to hourly, daily, weekly, monthly and annual IPE aggregates;
• a rolling year of history for every aggregate;
• retention of aggregates covering one day or longer for the software rental term or, where that does not apply, the six-year conventional lifetime;
• relevant statistics, including mean, minimum and maximum, for the different aggregates;
• periodic IPE monitoring reports;
• comparison with reference values and thresholds, using at least consumption statistics derived from the available history; and
• an explicit alarm when a set threshold is exceeded, such as an SMS, email or notification.

The IPE must be visible on at least one digital medium: a dedicated display, website, tablet or smartphone application, or dedicated software application.

Define an alarm as an operational record. Store the indicator, threshold, comparison window, trigger time, recipient, delivery result, acknowledgement and return-to-normal time. That makes the required alert reviewable and prevents an alarm setting in a configuration screen from being mistaken for evidence that a notification reached its user.

Supplier-meter consumption is expressly excluded

A35-2 states that consumption collected from energy-supplier meters is not eligible for calculating the IPE. The Part A declaration repeats that boundary, and the current control rules treat collection from those meters as a reason to classify the operation as unsatisfactory.

Supplier data can still be useful outside the eligible IPE calculation. Keep it as a separate site-level reconciliation record to identify unmetered loads, data gaps or a boundary mismatch. Do not substitute it for measurement at the equipment or equipment-group boundary claimed under IND-UT-134.

This distinction also separates operational metering from revenue settlement. A supplier meter is authoritative for the billed boundary. The IND-UT-134 system needs measurements at the claimed industrial-use boundary and a paired production or service quantity. Each record serves its own purpose.

Assemble the evidence before submission

The proof of completion must identify the measurement and monitoring system, acquisition of the measuring elements, any purchase of energy-management software, the covered energy uses and the nominal power in kW of each measured item.

The operation-specific evidence includes:

1. Prior study. Dated and signed by the professional or design office that prepared it.
2. Software description. From the manufacturer or installer, covering IPE calculation, display and history, alarms and periodic reports.
3. Software contract. Where the software is rented or supplied by subscription, including its duration.
4. Instrument schedule. Brand, reference, quantity, physical variable, measured equipment and whether each instrument is existing or new.
5. Existing-instrument inventory. Use, measurement, location, operational check, suitable reading frequency and plausibility of results, with the required dated and signed or quality-system record.
6. IPE monitoring report. Produced by the software, dated and signed by the beneficiary, based on at least one month of operating history and comparing actual IPE values with references and thresholds.
7. Summary by energy use. Energy use, nominal power, equipment type and site identity, IPE and collection interval.

Current CEE controls make these boundaries practical acceptance criteria. An on-site control is unsatisfactory if the preliminary study is missing or incomplete, the equipment or use is outside scope, power is at least 10 MW, the formula does not pair energy with production or service, the interval is too slow, supplier-meter data feed the IPE, or required history, statistics, reports and alarms are absent.

For operations committed from 1 January 2025, the consolidated controls order lists a minimum satisfactory on-site control rate of 15% for IND-UT-134, with a further 30% controlled by contact. Those are claim-file controls. They do not replace the beneficiary's responsibility to qualify and test the complete installed system.

Commission the measurement, not only the dashboard

Commission each measurement from its physical source to the displayed indicator:

1. Confirm the equipment identity, nameplate power and claimed energy use.
2. Check the meter, sensor or counter against a local indication or controlled test.
3. Verify address, channel, data type, scaling, sign, unit and timestamp.
4. Observe a complete operating cycle and confirm the production or service counter covers the same period.
5. Force a known threshold crossing and verify that the explicit alarm reaches the intended recipient.
6. Reconcile aggregates from the raw interval through hour, day, week and month.
7. Introduce a missing or stale value and confirm that it remains visible rather than becoming zero production or zero energy.
8. Generate the first monthly report and trace every figure back to retained source data.

Use the energy monitoring commissioning checklist for the instrument and data-quality checks. The industrial process instrumentation application helps define process variables and safe interfaces before installation.

Where EpiSensor fits

EpiSensor can provide operational measurements at eligible equipment boundaries where the source and interface are supported. Electricity monitors can separate machines, production lines and utility systems. Pulse, M-Bus, Modbus and analogue interfaces can collect energy, heat, flow, pressure, temperature, operating state and production counters. Edge can retain interval history on site and serve approved data to an energy-management platform.

That can support a measurement architecture with ten-minute records, aligned energy and production data, visible quality states and retained evidence. The complete project still needs software that supplies every required aggregate, statistic, report, comparison and explicit alarm.

EpiSensor does not determine CEE eligibility, perform the required preliminary study, certify NF EN 17267 steps, calculate the certificate award or assemble and submit the legal claim. The beneficiary and its CEE professionals remain responsible for the current operation sheet, controls, evidence and application.
