Energy saving has become one of the main objectives of public and private policies in Spain., in response to the need to improve efficiency and reduce both economic costs and polluting emissions. The promotion of Energy Saving Certificates (ESCs), along with new aid and subsidies, is enabling citizens, businesses, and administrations to benefit financially from improvements in energy efficiency.
In recent months, initiatives have multiplied aimed at monetizing energy savings, incentivizing both building renovation and the replacement of household appliances and the purchase of electric vehicles. In addition, several regions have launched their own programs to facilitate the energy transition and achieve the goals set out in the National Integrated Energy and Climate Plan.
Energy Saving Certificates: How They Work and Who Can Benefit
The Energy Saving Certificate system It allows for the accreditation and monetization of savings generated through energy efficiency measures, whether in homes, public buildings, or vehicle replacements. Each CAE is equivalent to 1 kWh of final energy saved over a year, and its achievement depends on verification of the improvements made.
The Ministry for the Ecological Transition and the Demographic Challenge launched this system with the aim of accelerating the reduction of energy consumption in all sectors. Companies, public administrations, and individual consumers can participate, either directly or through delegated agents who manage the procedures and certification.
One of the main advantages of the CAE The savings achieved can be converted into income by selling them to obligated entities—energy companies or large consumers—so that they can meet their own savings targets stipulated by Spanish and European regulations.
In practice, CAEs have become a key tool to boost investments in rehabilitation and renovation of air conditioning, lighting, and insulation systems, as well as in promoting electric mobility and efficiency in industry.
Aid and incentive programs for energy savings
Many autonomous communities have launched specific programs to facilitate access to efficient solutions that enable CAE. For example, La Rioja has launched a new edition of the Appliance Renewal Plan, which offers a 25% bonus and up to 150 euros for the purchase of appliances with high energy efficiencyThe goal is to promote the replacement of old equipment, helping to reduce both electricity consumption and emissions. Beneficiaries can replace up to three appliances, and priority is given to products such as refrigerators, washing machines, dishwashers, and dryers with the best energy labels.
For its part, the Provincial Council of Córdoba has activated subsidies to improve energy efficiency in senior residences and pensioners' homes. This aid line, endowed with €300.000, finances up to 80% of projects that reduce annual energy consumption by at least 15%, focusing investment on improvements in air conditioning, lighting, building envelopes, and facility regulation.
These programs help households and social organizations reduce their energy bills and access more sustainable equipment, while also helping to meet regional environmental goals.
New opportunities in electric mobility and savings monetization
In the automotive sector, CAEs have been added as an additional incentive for those who purchase a new electric vehicle. Today, brands such as BYD and Renault offer direct discounts ranging from 800 to 1.500 euros for the purchase of an electric car, provided that a previous combustion vehicle is traded in, sold, or scrapped. This bonus is in addition to the traditional aid from the Moves III Plan, allowing buyers to maximize savings.
The process to access these incentives is simple, as accredited dealers or intermediaries are responsible for processing the necessary documentation and applying the discount directly to the vehicle's price. Thanks to compatibility with other public and private subsidies, purchasing an electric vehicle is much more affordable.
Furthermore, this mechanism is not limited to individuals: companies, self-employed workers and public entities They can also benefit by renewing fleets or service vehicles, contributing to more sustainable and profitable mobility.
Regulatory developments and industry participation
Recent regulatory developments have opened new avenues for the industrial sector to actively participate in the energy savings system. The proposed ministerial order currently under public consultation defines the conditions for energy-intensive companies—especially those engaged in extractive and manufacturing activities—to be able to accredit and monetize their efficiency measures.
To do so, companies must meet requirements such as being registered in Spain, demonstrating an average consumption of more than 1 GWh over the last three years, and having completed an energy audit, among others. Certified savings can be included in both the National System of Energy Efficiency Obligations and the CAE (National Energy Efficiency System), allowing the industry to obtain an economic return on investments made in reducing consumption.
These measures complement the efforts of local administrations, such as Zaragoza City Council, which has pioneered the auction of energy savings generated by municipal facility projects. Initiatives such as those of Moeve and the College of Technical Industrial Engineers of Madrid are facilitating the grouping and certification of savings promoted by professionals, improving accessibility and streamlining the process for converting them into CAE.
