"This is a milestone for us and for the city's climate transition. I am both happy and proud that in a short time we are ready to take this last step in the conversion of district heating. With the new facility, we become independent of natural gas and can offer our customers 100 percent renewable and recycled district heating. We also increase security of supply, add a new source for local electricity production and strengthen the competitiveness of district heating," says Per-Anders Gustafsson, CEO of Göteborg Energi. 

“We are very proud to continue our long and close cooperation with Göteborg Energi. The plant itself will certainly be a state-of-the-art showcase of how sustainable resources can be turned into energy with the highest efficiency. It is great to work together with Göteborg Energi and take its operations forward,” says Antti Laaksonlaita, Director, Energy Plant Solutions, Valmet.

Information about Valmet’s delivery

Valmet’s delivery will include a 140 MWth Valmet BFB Boiler plant utilizing bubbling fluidized bed technology as well as a flue gas cleaning system and a flue gas condensing system. Start-up of the plant is scheduled for 2025.

Additionally, Valmet will deliver a boiler building and piping to connect the new boiler to the existing steam turbine. Operations and maintenance services including Valmet Industrial Internet solutions will maximize reliability and optimize performance, thereby ensuring safe and more sustainable production throughout the plant lifecycle.

The new biofuel-fired steam boiler will be integrated with Göteborg Energi's existing facility Rya power plant. The boiler is estimated to contribute 156 megawatts of heat and 39 megawatts of electricity to the local energy system. The plant is flexible and can run on several different types of biofuels. Mainly forest chips (GROT) and recycled return wood (RT chips) from the region will be used.

"Rya cogeneration plant plays an important role in Sweden's electricity supply. By integrating the new boiler with our existing plant, we gain great 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 a security for Gothenburg and the citizens of Gothenburg," says Gustafsson.  

Göteborg Energi AB is fully owned by the city of Gothenburg in Sweden. Besides developing and supplying new solutions within energy production and broadband connections, the company is also working toward a bigger goal – a sustainable Gothenburg. Göteborg Energi has almost 1,000 employees who work to make the city more sustainable.
