Valmet Enhances Gren Tartu's District Heating Efficiency

In a significant step towards sustainable energy, Valmet, a leader in process technologies, has secured an order from Gren Tartu to supply a flue gas condenser and heat pumps for their biomass heat and power facility in Tartu, Estonia. This strategic move aims to enhance the heat output to the local district heating network, marking a progressive leap in energy efficiency for the region.

The delivery includes innovative equipment designed to reclaim heat from the plant's flue gases. By utilizing heat pumps, the system will transform this reclaimed heat into a form that is suitable for district heating. Valmet's innovative solution is expected to contribute an additional 10 megawatts of heat to the existing district heating network, enabling cleaner and more efficient energy production with reduced fuel consumption.

Margus Raud, Head of Technical Development at Gren Tartu, emphasized the importance of expanding their heating capacity. He stated, "Increasing our heat production capacity is a key priority for us, and environmentally sustainable solutions that utilize waste heat are the most effective way to achieve this increase. Our long-standing partnership with Valmet has proven essential due to their expertise and reliability."

Valmet's Director of Environmental Solutions, Lari-Matti Kuvaja, added, "This project exemplifies how flue gas heat recovery combined with heat pump technology can enhance a plant’s energy efficiency while ensuring a reliable heat supply. We are looking forward to supporting Gren Tartu with a solution that efficiently captures low-temperature heat and makes it usable for district heating."

The equipment's ability to recover low-temperature heat not only amplifies the overall energy efficiency of the Gren Tartu plant but also minimizes emissions and cuts down on fuel consumption. This dual benefit of increased energy output and reduced ecological impact aligns perfectly with the global push for sustainability and efficient energy solutions in urban areas.

Gren, the parent company of Gren Tartu, stands out as a major player in the Northern European energy infrastructure market, specializing in district heating and cooling solutions alongside renewable energy services. Operating predominantly in the Baltics and the UK, Gren boasts a production capacity of 1,500 megawatts and an impressive annual energy sales figure of approximately 3.0 terawatt hours. Notably, over 95% of the energy produced by the company relies on renewable and recovered fuels, underpinning its commitment to sustainable practices.

In Estonia, Gren Tartu ensures the provision of clean and reliable district heating services for a wide array of customers, including offices, hospitals, and individual residences. The company is also focused on developing district cooling solutions tailored to commercial clients, further reinforcing its versatility in the energy sector.

This collaboration between Valmet and Gren Tartu not only signifies a leap in local heating capabilities but also serves as a model for future projects in the realm of sustainable energy solutions. With the order now included in Valmet’s second-quarter reports for 2026, the details surrounding its financial implications remain undisclosed. However, the focus remains on the tangible benefits this technology will bring to both Gren Tartu and the community it serves.

In conclusion, the partnership between Valmet and Gren Tartu represents a forward-thinking approach to district heating in Estonia, showcasing how innovative technology can play a critical role in enhancing energy efficiency while adhering to sustainable practices. As cities worldwide strive to become greener, this project sets a significant precedent for implementing energy-saving solutions that can meet modern demands without compromising environmental standards.
