Naturgy and Ence have been the protagonists of the largest energy efficiency operation within the new system of Energy Saving Certificates (CAE) promoted by the Ministry for the Ecological Transition and Demographic Challenge.
The project consisted of Ence implementing an advanced technology project to increase the energy efficiency of its boilers as part of the company’s strategic commitment to innovation in its production centres.
The operation has been verified by AENOR, a leading entity in the generation of trust, responsible for validating the savings and issuing the positive report for requesting certificates. This is the largest volume of CAE issued to date in Spain.
A CAE is an electronic document that certifies a specific annual energy saving resulting from an energy efficiency action. In terms of measurement, one CAE is equivalent to 1 kWh of energy savings. Naturgy’s action at the Ence factory has obtained 191 million certificates.
Commitment to customers
Naturgy is committed to being one of the key players in the energy transition towards a circular and decarbonised economy model. Within the CAE System, the company offers its customers a “turnkey” service that includes advice on investments aimed at improving energy efficiency, calculation of energy savings and all the associated document management so that the consumer can benefit from the CAE. In 2024, the company was recognised by the Ministry for the Ecological Transition and Demographic Challenge for being the first energy company to settle CAE in 2024.
Ence has carried out this transaction in a hitherto unprecedented scenario which, for the first time, allows energy trading companies to use energy consumers to meet energy efficiency targets by purchasing CAEs. With this collaboration, Ence reaffirms its participation and commitment to the energy transition towards a circular and decarbonised economy model.
