Industrial energy efficiency means reducing the energy required for production without compromising quality or volume. Against a backdrop of volatile energy prices and tightening regulatory obligations (mandatory energy audit, CSRD, industrial decarbonisation), it is a direct lever of competitiveness. Energy efficiency protects margins and reduces the carbon footprint.

It depends on your activity and your initial energy consumption. Depending on the site, reductions of between 10% and 60% can be achieved.

Measurement and verification of savings relies on the IPMVP (International Performance Measurement and Verification Protocol), the international reference recognised by AFNOR. It builds on an energy baseline established before the works, calibrated meters and sensors, and adjustment models that account for variations in production. This approach delivers objective, auditable results that meet the requirements of funding bodies. Our IPMVP-qualified team provides detailed reports at every stage.

The first step is usually an energy audit: it establishes an objective picture of your consumption, identifies savings potential across utilities and processes, and prioritises actions according to their profitability. It lays the foundations of an operational roadmap. Depending on your level of maturity, it can be complemented by support in energy management or by the implementation of the ISO 50001 standard. Lemon Energy adapts its involvement to your situation.

The ISO 50001 standard sets out the requirements for an energy management system (EnMS). It structures a continuous improvement approach: analysis of significant energy uses, definition of quantified objectives, performance indicators, regular review. For large industrial companies subject to the mandatory energy audit, it constitutes a recognised alternative. It also enhances the credibility of the approach with clients, funders and ESG stakeholders. Lemon Energy supports you from preparation through to certification.

Several schemes can significantly reduce the cost of your investments: Energy Savings Certificates (CEE), ADEME's Fonds Chaleur, regional industrial modernisation grants, and the PACTE Industrie programme, which funds up to 43% of the support provided.
