Valmet’s automation system’s high reliability and proven availability combined with our experience of Valmet’s local Austrian team met our distinctive quality requirement and led to this order. In addition, Valmet’s long experience in automation and process technology paired with sustainability and reliability convinced us.”
The existing turbine protection and control systems are reaching the end of their technical service life, and the availability of spare parts is diminishing. The automation upgrade project aims to ensure the functionality of the systems until the end of the power plant’s lifetime. Valmet was selected because it’s a technologically advanced Finnish company, and we have collaborated well on several projects at Fortum’s power plants.”
