The city of Zamora has inaugurated a new district heating network powered by renewable energy, promoted by DH Ecoenergías Zamora, a company majority-owned by Suma Capital through its SC Infra investment strategy specializing in sustainable infrastructure for the energy transition, and by ENGIE, a globally recognized energy group.
This project represents a significant step toward the decarbonization of urban heating, combining technological innovation with a commitment to local and renewable sources. It is an example of public-private collaboration aimed at transforming the energy model of medium-sized cities.
The new infrastructure features a capacity of 20 MW and a route of 20 kilometers of pre-insulated pipes, extending from the eastern area of Zamora to Tres Cruces Street, preserving the integrity of the historic city center. It will be mainly powered by locally sourced forest biomass, certified under the SURE system, which ensures responsible forest management, promotes local employment, and helps reduce the risk of forest fires.
Once in operation, the network will connect more than 7,300 households, supplying renewable thermal energy. This will reduce CO₂e emissions by approximately 11,000 tons per year and significantly improve the energy efficiency of the connected buildings, whose thermal demand accounts for nearly 70% of their total emissions.
Among the main advantages of the system is its collective efficiency: it will replace individual boilers with a single centralized system, reducing fossil fuel consumption and improving safety in household installations. Additionally, its design allows for the progressive integration of new clean technologies without the need for major renovations.
Designed to operate for decades, this infrastructure represents a scalable solution with long-term impact. Aligned with global sustainability goals, the initiative will contribute particularly to SDG 7.1, by increasing the share of renewable energy in the energy mix, and SDG 13.3, through the strengthening of institutional and technical capacities for climate change mitigation and adaptation.
The event was attended by Pablo Novo, City Councilor of the Zamora City Council; Ruperto Unzué, partner of Suma Capital; Janis Rey, Managing Director of ENGIE Local Energy Infrastructures and President of the Association of District Heating and Cooling Companies (ADHAC); Xavier Puyal, CEO of DH EcoEnergías; Pablo Pérez Suárez, Business Development Manager at Ferrovial and ADHAC representative; and Davis Zinetti, CEO of UNICONFORT.

About ENGIE SPAIN
With a strong presence across the entire energy value chain in Spain for over 25 years, and with more than 1,700 employees nationwide, ENGIE’s strategy focuses on producing energy with the utmost respect for the environment and supporting its clients in their journey toward carbon neutrality. ENGIE enables access to cleaner energy, more sustainable cities, and more efficient industries.
Its decarbonization strategy relies on two levers: transforming its own energy production through the development of renewable energy, and supporting clients' decarbonization via industrial solutions that help reduce energy costs and CO₂ emissions.
ENGIE is the sixth-largest power producer in the country, with an installed capacity of around 3,700 MW, including 1,700 MW of renewable assets—wind, solar, and small hydro—and 2,000 MW of flexible, low-carbon generation. Together with its clients, ENGIE develops and manages over 300 MW of assets that bring the energy transition to life (industrial self-consumption photovoltaic or solar thermal plants, biomass boilers, and cogeneration units). The company also works in energy trading and management and is a leading player in structuring and launching long-term renewable power purchase agreements (PPAs).
ENGIE is a national leader in district heating and cooling networks (Barcelona, Zaragoza, Pamplona, Palencia, etc.) and has extensive capabilities in the design, implementation, and operation of industrial solutions to help clients use energy more efficiently and sustainably.
ENGIE’s key strength lies in its ability to comprehensively manage the entire energy value chain, handling the financing, construction, operation, and maintenance of all types of industrial decarbonization assets. These attributes make ENGIE the benchmark partner in Spain for accelerating the energy transition and building a better, more sustainable future.
