Spain’s Certificado de Ahorro Energético (CAE) offers up to €1,000 off a new electric car—on top of other incentives. Here’s how this system works, who qualifies, and why more buyers are starting to take advantage.
Buying a new electric car in Spain can come with a significant, often overlooked discount: the Certificado de Ahorro Energético (CAE). This digital certificate, introduced by the Ministry for Ecological Transition, allows buyers to save up to €1,000 on a new electric vehicle—on top of existing government grants. Yet, despite its growing presence at dealerships, many drivers remain unaware of how the CAE works or how to claim it.
What Is the CAE?
The CAE is an official electronic document that certifies a measurable reduction in energy use. It was created as part of Spain’s broader push to meet EU energy efficiency targets. When you replace a combustion-engine car with a fully electric model, you generate a quantifiable energy saving. This saving is converted into a CAE, which can then be transferred to an authorized energy company. In exchange, the buyer receives a direct financial benefit—typically up to €1,000, though the amount can vary.
Unlike a traditional subsidy, the CAE is not a government handout. Instead, it’s a market-based mechanism: you’re effectively selling the energy savings your new car generates to a company that needs to meet legal efficiency obligations. The system is open to private individuals, self-employed workers, businesses, and public administrations, but only for the purchase of 100% electric vehicles. Hybrids and plug-in hybrids are not currently eligible.
How to Claim the Discount
For most buyers, the process is straightforward. In many cases, the dealership handles the paperwork: during the purchase, you sign over the rights to your energy savings and provide the necessary documentation, including proof that you’re scrapping a combustion vehicle. The authorized company then processes your application within the CAE system.
If your dealership doesn’t offer this service, specialized firms can manage the CAE process after you’ve bought the car. Depending on the brand and dealer, the discount may be applied immediately at the point of sale, or you might receive the payment after the certificate is validated—a process that can take up to six months. Increasingly, however, buyers see the CAE amount deducted directly from the purchase price, making the benefit immediate.
Stacking with Other Incentives
One of the CAE’s biggest advantages is its compatibility with other official grants, such as the current Plan Auto+. Because the CAE and Plan Auto+ are separate mechanisms, buyers can combine them for maximum savings. For example, the Plan Auto+ can reduce the price of a new electric car by up to €4,500, and the CAE can add another €1,000, bringing the total potential discount to €5,500.
Unlike government grants, which depend on annual budgets and application windows, the CAE is tied to the market value of energy savings and is generally easier to obtain. The process is especially simple when the dealership manages the paperwork, but even if not, third-party companies can help buyers access the benefit.
Context and Practical Tips
Spain’s push for electric mobility is part of a wider European trend, with new incentives and regulations reshaping the car market. As the CAE becomes more widely adopted, it’s worth comparing how different brands and dealers handle the process. For those interested in the broader landscape of automotive innovation, the arrival of high-performance models—such as the new Porsche 911 GT3 S/C, which brings race technology to the road—shows how the industry is evolving on multiple fronts.

To maximize your savings, check with your dealer about CAE eligibility before committing to a purchase, and ensure you have all required documentation for scrapping your old combustion vehicle. As Spain continues to incentivize cleaner transport, the CAE stands out as a practical, underused tool for reducing the cost of going electric.
