The finding

The of the five were worn out and all their heat was going into the air, while was produced by conventional means.

What KELP did

KELP replaced the with six , installed by helicopter and crane on a fully operating site.

The result

850 t CO₂/yr

CO₂ avoided across the whole site

Equal to the annual carbon footprint of about 100 French people, or 6 million km driven every year in a petrol or diesel car

The site has 4 operations: the CO₂ avoided, the CEE volume and the project duration are for the whole site.

Energy savings certificates (CEE)

Works funded by energy savings certificates (CEE)

How we calculate the CO₂ avoided : The CO₂ avoided is estimated from each project's volume of energy savings certificates (CEE), expressed in kWh cumac, that is, cumulated over the conventional lifetime of the works and discounted at 4% per year. This volume is converted into the energy saved in one year, then multiplied by the emission factor of the energy replaced: 0.065 kg CO₂/kWh for electricity used for domestic hot water, 0.227 kg CO₂/kWh for natural gas (regulatory values from the French order of 31 March 2021). Comparisons: average carbon footprint of a French person, 8.2 t CO₂e per year (SDES, 2024); petrol or diesel car, 142 g CO₂e per km, manufacturing included (ADEME, Impact CO2, 2025).
