Mitsubishi and Stockholm Exergi modernise the CHP plant

Mitsubishi Power Europe has signed a contract with Stockholm Exergi to modernize the combined heat and power (CHP) plant – Kraftvärmeverk 1 (KVV1) at Värtaverket, Stockholm. Mitsubishi Power Europe will modernize the boiler to handle sustainable recycled fuels like bio-oil. The large-scale renovation involves automating the plant’s control system to a modern distributed control system (DCS) and installing new low NOx burners to reduce nitrogen dioxide 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.

Stockholm Exergi contributes to increasing resource efficiency by using renewable or recycled energy sources; 99% of the district heating is generated from renewable or recycled fuels.

The renovation project will enable higher energy efficiency and local renewable electricity production. Both are key to achieving positive climate impact, while ensuring affordability and reliability of power. The integrated DCS will enhance plant efficiency and reliability, improve system availability and enable remote monitoring, control and reporting.
