    Power infrastructure firm Mitsubishi Power will modernize a combined heat and power (CHP) plant in Sweden for the local district heating utility.

    Stockholm Exergi selected Mitsuibishi Power Europe to update the boiler at Kraftvärmeverk 1 (KVV1)  plant in Värtaverket—originally built in 1976 to burn fossil fuels—so that it can handle sustainable recycled fuels like bio-oil. Mitsubishi Power will also automate the plant’s control system and install new nitrogen oxide burners to reduce NOx emissions.

    The project also includes repairing pressure parts, installing selected sub-systems, and upgrading critical components. The CHP plant will be fully commissioned during the heating period in 2023 following two scheduled outages during the summer months for retrofitting.

    “The bio-oil used in KVV1 is obtained from the food and cosmetic industry residues,” Elvira Alberg, project manager at Stockholm Exergi, said. “Retrofitting the existing firing system to handle bio-oil from heavy fuel oil will significantly extend the operational lifetime of the plant.”

    “What makes this project unique is its complexity. The diverse combination of works, including installing a suitable biofuel firing system and modern automation systems, are addressed in a single project,” Carlos Gonzalez Peton, CEO of Mitsubishi Power Europe, said.

    Stockholm Exergi provides heating and power to more than 800,000 customers in Sweden, including hundreds of hospitals, data centers and businesses.
