Kainuun Voima has selected Valmet to modernise the automation and electrical systems across the Koivukoski II, Koivukoski III and Ämmäkoski hydropower plants in Kajaani, Finland. Booked during the third quarter of 2026 for an undisclosed value, the upgraded infrastructure is scheduled to enter service in the fourth quarter of 2027.
Under the agreement, the supplier will replace existing third-party controls with its web-based DNAe distributed control platform. The delivery encompasses turbine controllers, balance of plant automation and supervisory control and data acquisition functions, enabling centralised monitoring of all three facilities from a single control room.
The electrical scope includes new synchronising equipment, generator protection upgrades and flood protection at Ämmäkoski, alongside medium and low-voltage system improvements at Koivukoski III. Situated on the Kajaaninjoki River, the three plants hold a combined capacity of approximately 30MW.
