GreenYellow supports Stellantis’ decarbonization with an innovative comprehensive energy transition project

GreenYellow, a global leader in decentralized energy transition, takes a new step in supporting Stellantis, global car manufacturer and provider of innovative mobility solutions, in the decarbonization of its Madrid plant. This ambitious project marks a significant turning point for the automotive industry by integrating three strategic pillars: solar energy production, electrification of thermal processes, and energy storage. Thanks to this combination of innovations, Stellantis Madrid plant significantly reduces its carbon footprint and is fully committed to carbon neutrality, as reflected in its “Dare Forward 2030” plan, while also strengthening its goal of sustainable energy independence for its production process.

Transforming the Madrid plant: three pillars for sustainability

1. Solar energy production:

Installation of a ground-mounted photovoltaic plant with a capacity of 4.6 MWp, generating around 7 GWh annually for self-consumption. This system complements the existing rooftop installation, bringing the total capacity to 12.9 MWp and annual production to 18.8 GWh. Commissioned by GreenYellow, this second phase reduces CO₂ emissions by 931 tons per year – the equivalent of the consumption of a village of 400 inhabitants – and offsets its environmental impact through the planting of 4,700 trees, forming a forest the size of nine football fields.

2. Electrification of thermal processes:

Replacement of gas boilers with heat pumps, achieving energy savings of 57%, equivalent to 2,9 GWh per year, and a reduction of 1,218 tons of CO2 annually.

3. Energy storage:

Installation of a 25 MWh BESS Battery Energy Storage System (BESS), according to GreenYellow currently the largest in Europe for photovoltaic self-consumption. This system, supplied by Sungrow, includes advanced technologies such as liquid cooling, artificial intelligence, and a high-security system, ensuring greater energy independence. The integration of energy storage solutions will not only stabilize the site’s energy supply during periods of high demand but also optimize costs by reducing consumption peaks. These solutions strengthen infrastructure resilience while supporting Stellantis’ environmental commitments.

An investment in a sustainable future for the automotive sector

This project reflects a notable success in its rapid implementation and execution. The contract for the photovoltaic system was signed in June 2024 and is already operational. The heat pumps contract was signed in August 2024, and are already operational, while the battery contract, signed in December 2024, will be ready to go into service in the summer of 2025.

This project not only reinforces Stellantis’ commitment to carbon neutrality but also strengthens its goal of sustainable energy autonomy for its production centres. Additionally, thanks to the rapid implementation, Stellantis benefits from its operational competitiveness.

Collaboration and local impact

The collaboration between GreenYellow, Stellantis, Icoenergía, and Sungrow, companies located in close geographical proximity, has been key to ensuring efficient execution. Thanks to this local approach, the hiring of nearby labour and the creation of synergies that benefit the community have been promoted.

“This comprehensive model represents the future of the industry, combining renewable energies, storage, and electrification in an effective strategy to reduce the carbon footprint” highlighted Nicolas Daunis, General Manager of GreenYellow Iberia.

Jesús Cánovas, Managing Director of Icoenergía, highlighted the strategic value of the project:
“This project has been an exciting challenge and a unique opportunity to demonstrate the value that Icoenergía brings when it comes to transforming the industry towards a more efficient and sustainable model. From technical execution to the coordination of cutting-edge equipment and technologies, we have worked with precision, commitment and vision. But beyond the measurable results, we are deeply proud to be part of an initiative that drives the real decarbonization of the automotive sector. Together with partners such as GreenYellow, Stellantis and Sungrow, we are demonstrating that the energy transition is not only possible, but already underway.”

For his part, Iker Labiano García, Sungrow’s ESS manager in Spain and Portugal highlighted the importance of energy storage: “With the PowerTitan 2.0, we are setting new standards for efficiency and safety in energy storage. Our mission is not only to push the boundaries of technology, but also to empower our partners to achieve their sustainability goals.”

Impact and benefits for the industry

The simultaneous implementation of these three initiatives demonstrates how collaboration between companies can drive the transition to a more sustainable energy model. This project not only benefits Stellantis by stabilizing its energy costs and maximizing operational efficiency but also sends a strong message to the automotive sector: decarbonization is viable and necessary to maintain competitiveness in a constantly evolving market.

Innovation that inspires the sector

With cutting-edge technologies, advanced monitoring tools, and an energy management model based on artificial intelligence, this project stands as an example of innovation to follow. Any company with available space and traditional heating systems can replicate this model, taking advantage of the benefits of electrification and solar energy.
