For the past few months, Heineken Spain has undergone a significant transformation in its beer production methods : all its beers, ciders, and tinto de verano (a refreshing summer wine drink) are now brewed using only renewable energy. With this step, the Spanish subsidiary of the Dutch group has become the first major brewery in the country to operate its production with a 100% renewable energy mix , paving the way for many other industries to watch closely.
This move not only impacts the domestic beer market. Spain has become the first country in the Heineken NV group to complete the energy transition of all its brewing processes , bringing forward by five years the internal goal of achieving net-zero emissions in production by 2030. The global objective remains: to achieve climate neutrality across the entire value chain by 2040, but the Spanish subsidiary is already serving as a testing ground and benchmark within Europe.
What does it mean to produce beer using only 100% renewable energy?
The company insists that the achievement goes beyond simply changing the electricity contract. The real leap forward has been transforming both the electrical and thermal energy used in its factories, something especially complex in industrial processes like brewing, where heat is essential for pasteurizing, boiling, and cooking the product.
In the words of its president, Etienne Strijp, "decarbonizing industrial heat has been an enormous challenge" that has required investing in new technologies, taking risks, and working for almost a decade with specialized partners. There was no pre-existing manual, so the project has been adjusted as it has gone along, with energy efficiency solutions and different renewable sources adapted to each plant.
Heineken Spain explains that its breweries now consume around 80% less energy than they did a few years ago , thanks to process improvements, more efficient equipment, and very precise energy management. The remaining energy demand is met by a combination of renewable technologies that generate both electricity and heat.
The solutions deployed include photovoltaic installations, solar thermal plants, biomass boilers, biogas production, and the use of biomethane . This mix allows energy to be adapted to the type of heat or electricity required at each stage of the process, minimizing dependence on fossil fuels and promoting circular economy models : agricultural waste or byproducts are transformed into usable energy.
An investment of over 80 million and a decade of work
This milestone is not the result of a last-minute decision. The company cites a nearly ten-year industrial roadmap , with intermediate objectives, pilot projects, and progressive deployments across its four major factories and associated centers. During this period, it has mobilized over €80 million in joint investment with its energy partners , in addition to various public grants and European funds earmarked for promoting decarbonization.
Executives like Carmen Ponce, Director of Corporate Affairs and Sustainability , explain that the key has been maintaining determination even during challenging business periods, such as the pandemic or times of high energy volatility. They emphasize that the strategy has focused on fundamentally transforming production processes, not on offsetting emissions through external mechanisms.
This effort has been accompanied by an independent verification system. The progress has been subjected to external audits—for example, by the consulting firm EY— to certify that energy consumption, its origin, and the actual reduction in emissions meet the required standards.
At the same time, the company highlights the competitive advantages : anticipating future regulations, facilitating access to sustainable financing, strengthening its corporate reputation, and generating value in the regions where it operates. Management emphasizes a recurring idea: the best energy is the energy that isn't consumed, and the second best is that which is produced cleanly and close to industrial centers.
The strategic role of Andalusia in Heineken's decarbonization
Heineken Spain's energy transformation has a distinctly Andalusian flavor . This region is home to two of its four large breweries—Seville and Jaén—and two microbreweries in Seville and Málaga, as well as some of the company's most emblematic renewable energy projects in its decarbonization plan.
One of the key milestones is the Seville solar thermal power plant, developed in partnership with Engie , considered one of the largest facilities of its kind for industrial use in Europe. This infrastructure supplies high-temperature renewable heat, essential for replacing fossil fuel-fired boilers and ensuring the continuity of the brewing process without compromising product quality.
In Jaén, the focus has been on biomass. The plant uses olive grove waste to generate renewable thermal energy , an example of a circular economy in which agricultural byproducts from the region are transformed into clean fuel for industry. This system reduces emissions, gives a second life to agricultural byproducts, and contributes to local economic activity.
These projects are complemented by the El Andévalo photovoltaic plant in Huelva, a joint venture with Iberdrola , which supplies 100% renewable electricity to meet a significant portion of the brewery's electrical needs in Spain. Thanks to this portfolio of assets, Andalusia is solidifying its position as one of the brewery's key energy and production hubs.
The Andalusian Minister of Industry, Energy, Mines, and Digitalization, Jorge Paradela , emphasized that these types of initiatives align with the region's strategy to make decarbonization an economic driver . With nearly 70% of its electricity generation coming from renewable sources—above the national average—Andalusia aims to attract new industry precisely because of its capacity to offer clean energy at competitive prices.
Valencia and Madrid: solar thermal, industrial steam and green electricity
Heineken's renewable energy roadmap is completed with the Quart de Poblet plant (Valencia) and the San Sebastián de los Reyes center (Madrid) . Each has required specific technical solutions, especially in the case of Valencia, where the main challenge was producing industrial steam at the correct temperature.
In Valencia, the company has worked with Solatom and CSIN, led by Miquel Frasquet , to design a solar thermal system tailored to the factory's specific needs. This project, considered an international benchmark, has received European financial support through the Institute for Energy Diversification and Saving (IDAE), which channels ERDF funds for industrial decarbonization . The total investment in this plant is around €3 million, approximately half of which comes from public funding.
The Valencian Community is thus positioning itself as a laboratory for solar thermal technology applied to industry , with a model that other heat-intensive sectors—beyond beer—are viewing as an alternative to natural gas. Experience shows that, with the right design, it is possible to generate steam from solar energy in a stable and competitive manner.
In Madrid, the San Sebastián de los Reyes brewery fits into the overall scheme for using renewable electricity and optimizing consumption . Together with Seville, Jaén, and Quart de Poblet, it forms the industrial hub that supplies the Spanish market with more than 9,9 million hectoliters of beer per year, equivalent to approximately 13 million pints per day.
The combination of these centers and their associated infrastructures has allowed all brands produced in Spain—Cruzcampo, Heineken, Amstel, El Águila, Ladrón and other local brands—to be produced with 100% renewable energy , both in the electrical and thermal aspects, since December 2025.
Business alliances and local technology as key levers
At the project launch in Madrid, the company emphasized the role of its energy partners and the importance of establishing long-term relationships to make investments of this magnitude viable. Participants included Mario Ruiz-Tagle, CEO of Iberdrola Spain ; Janis Rey, Head of Local Infrastructure at Engie Spain ; and Miquel Frasquet, Technical Director of CSIN and co-founder of Solatom , as well as Heineken Spain's own management team.
Business representatives agreed that these types of projects cannot be carried out alone . They require a shared vision, risk sharing, a commitment to long-term deadlines, and a willingness to learn as they go. The experience in Seville, for example, demonstrates that flexible and reliable solar thermal systems can be designed for industrial use; while in Valencia, solar steam solutions have been tested that can be extrapolated to other sectors.
Engie emphasized that the model developed at the Seville plant is replicable and combines security of supply with a drastic reduction in emissions . Iberdrola, for its part, underscored the value of supporting industry in complex decarbonization decisions, contributing both renewable generation and expertise in grid integration.
Heineken Spain has also received financial and regulatory support from public administrations . The central government has channeled aid—some 14 million euros, as detailed by Minister Sara Aagesen—to initiatives in Seville and Valencia, while the regional governments of Andalusia, Valencia, and Madrid have facilitated the processing and regulatory compliance of pioneering projects unprecedented in their sector.
This network of alliances is presented as a central piece of success: the industrial energy transition is conceived as a shared effort , in which companies, energy suppliers, administrations and technology centers contribute different capabilities to overcome technical and economic barriers.
Institutional support and message on the energy transition in Spain
The announcement of Heineken Spain's new phase was attended by a large number of institutional representatives. Sara Aagesen, Third Vice President of the Government and Minister for Ecological Transition and the Demographic Challenge , closed the event, accompanied by representatives from several of the autonomous communities involved.
The minister described the brewery's strategy as "an important milestone and an example of how the ecological transition is an economic and industrial opportunity ." She noted that the company had set 2030 as the target date for achieving 100% renewable energy in its production and that, in Spain, this goal has been reached five years ahead of schedule. In her view, this demonstrates that, with planning, sustained investment, and public-private collaboration, it is possible to accelerate decarbonization without losing competitiveness.
The government emphasized that Spain has particularly favorable conditions to become a European leader in renewables : availability of solar and wind resources, a transforming industrial sector, and access to EU funding. Cases like Heineken's are used as examples to illustrate that the transition is already generating measurable results and is not limited to long-term promises.
The regional ministers present—including Jorge Paradela (Andalusia) and Carlos Novillo (Madrid) —emphasized the impact of these types of projects on their territories. Beyond emissions reductions, they highlighted the job creation associated with the new facilities, the attraction of investment, and the modernization of the productive sector . The shared understanding is that where there is clean and abundant energy, it is easier to establish long-term industrial activity.
This institutional support has also resulted in a more stable regulatory environment for renewable energy investment. However, both companies and government bodies acknowledge that further adjustments to regulations and procedures are still needed to reduce administrative hurdles for similar projects and allow for faster deployment.
A practical case of decarbonization in mass consumption
Heineken Spain presents its experience as a practical case study in decarbonization within the consumer goods sector , combining economic logic with climate ambition. The company has stopped using fossil fuels in the production of its beers, ciders, and tinto de verano (red wine and lemonade) in Spain, addressing its direct and indirect emissions (scopes 1 and 2) and laying the groundwork for further progress throughout the supply chain.
In business terms, the company maintains that sustainability acts as a lever for competitiveness . Anticipating environmental regulations, reducing exposure to the volatility of fossil fuels, improving efficiency, and responding to the expectations of consumers, clients, and employees are factors that, according to its management, generate tangible value.
The size of the group also helps to contextualize this move. Heineken NV has more than 85.000 employees in over 70 countries and a portfolio of some 300 brands and 80 different varieties of beer and related beverages. In Spain, the subsidiary contributes nearly €5.000 billion to the national economy , around 0,3% of GDP, and maintains almost 1.400 direct jobs.
Among the brands produced in Spain are Cruzcampo, Amstel, El Águila, Heineken, Desperados, Ladrón, 18/70, and El Alcázar , as well as specialty beers like Guinness and Paulaner. Its four large breweries—in Seville, Madrid, Valencia, and Jaén—and the microbreweries in Seville and Málaga allow it to serve both the domestic market and select exports, all under the new umbrella of 100% renewable production.
Alongside its focus on climate action, the company maintains commitments to water management, waste reduction, and support for talent and the hospitality industry . Its four Spanish breweries are certified as Zero Waste to Landfill, and the company has set a goal of returning to watersheds a volume equivalent to the water contained in its beers and ciders. In addition, it offers training and employability programs through organizations such as the Cruzcampo Foundation.
With this comprehensive set of measures, Heineken Spain demonstrates how a large consumer goods company can transform its energy model without sacrificing its industrial scale. This case has become a benchmark for other markets within the group, as well as for companies in different sectors seeking concrete solutions to reduce emissions. The Spanish experience points to a simple yet demanding idea: with investment, planning, and sustained cooperation between industry, the energy sector, and institutions, decarbonizing complex production processes is not only technically feasible but can also strengthen the competitiveness and local roots of industrial activity.
