Göteborg Energi, a prominent energy company in Sweden, has greenlit a substantial SEK 2.53 billion (approximately €217.7 million) investment for the construction of a new biomass-fired steam boiler. The boiler will be seamlessly integrated into Göteborg Energi's existing Rya heat and power plant, marking a significant step in advancing sustainable energy solutions in the region.
This innovative biofuel-fired steam boiler is anticipated to make a substantial contribution to the local energy system, supplying 156 megawatts of heat and 39 megawatts of electricity. Notably, the facility offers versatility by operating on various types of biofuels, with a predominant focus on utilizing forest chips (GROT) and recycled wood (RT chips) sourced from the region.
The project is scheduled to become operational during the 2025/2026 heating season and will serve as a visually prominent landmark at the entrance to the Port of Gothenburg.
Similar biomass-fired facilities have been successfully established in various locations, including Borås, Gävle, and Kalundborg in Denmark, underscoring the viability and effectiveness of such renewable energy initiatives.
Over the past year, Göteborg Energi has diligently undertaken preparatory work encompassing permits, land conditions, technology, and procurement of key project components. The company has enlisted Valmet as the supplier of the boiler itself, Raumaster for external fuel handling, and Veidekke Entreprenad for ground and concrete work.
The transition to district heating powered by biofuels aligns with the City of Gothenburg's comprehensive environmental and climate program. The city's district heating infrastructure relies on recycled heat from industrial processes, waste incineration, and the integration of biofuels.
Per-Anders Gustafsson, CEO of Göteborg Energi, expressed his satisfaction with the project, stating, “This is a milestone for us and for the city's climate transition. I am both happy and proud that we are ready to take this final step in the transformation of district heating in a short time.”
Gustafsson emphasized the significance of achieving energy independence from natural gas, enabling the delivery of 100% renewable and recycled district heating to customers. The initiative also enhances energy security, introduces a new source of local electricity production, and reinforces the competitiveness of district heating.
Furthermore, Göteborg Energi's expansion endeavors encompass the creation of a bio-based hot water boiler in the Rya area and the development of a new district heating line from Mölndal, which will introduce bio-based district heating into the southern part of the network. Additionally, digital tools will play a pivotal role in enhancing efficiency and management.
Gustafsson concluded, “Rya heat and power plant plays an important role in Sweden's electricity supply. By integrating the new boiler with our existing plant, we gain a great deal of flexibility, not least in terms of fuels. With the new facility in place, our system can handle almost all fuels on the market, which is reassuring for Gothenburg and its residents”
