It is an electronic document that certifies an energy saving associated with an energy efficiency performance. One ESC is equivalent to 1 kWh, so if you save 500 kWh/year, you get 500 ESCs!

This instrument makes it possible to monetise energy savings by recovering part of the cost of energy efficiency investments through a consideration when selling the savings obtained

How to benefit from ESCs according to your project type

How to generate ESCs according to your project type

There are two main categories of projects that can generate Energy Saving Certificates:

Standardised projects: They follow standardised data sheets describing specific energy efficiency measures and expected savings. For example:
Improvements in air-conditioning and lighting If you install more efficient heat pumps or air conditioning, if you replace incandescent or fluorescent lamps with LEDs or if you refurbish or improve the insulation of the building.
Replacement of combustion engine vehicles If you replace gasoil or diesel vehicles by electric vehicles.
Electrification of engines If you install high-efficiency engines in your industrial processes.

Singular projects: These are unique and specific to each installation, taking into account its characteristics and needs. They require a detailed assessment and a customised verification process due to their unique nature. For example:
Modernisation of complex industrial processes If you implement advanced technologies to improve the efficiency of specific industrial processes.
Integration of energy management systems If you implement systems to monitor and controls the use of energy in large installations.

Any entity that implements energy saving measures can benefit from ESCs. This includes companies from all sectors, public organisations and individuals. Projects must meet specific eligibility criteria and undergo a verification process to ensure that energy savings are real and measurable.

Projects must comply with a number of technical and regulatory criteria established by the competent authorities. These criteria include demonstrating a significant, verifiable reduction in energy consumption, the use of technologies recognised for their efficiency, and detailed documentation of all stages of the project. In addition, projects must be audited by an accredited body to certify the savings achieved.

In general, the financing of energy efficiency actions whose savings end up as ESC will be compatible with public aid or subsidy programmes, except those financed by the FNEE (Order TED/815/2023, of 18 July, article 14.8).

Companies that generate ESCs can benefit from a number of economic and operational incentives. These include selling certificates in specialist markets, improving their reputation and competitiveness by adopting sustainable practices, and reducing their own operating costs by implementing energy efficiency measures. In addition, complying with energy saving regulations can avoid penalties and improve relations with regulators and customers.
