UPM Energy's Kuusankoski hydropower plant renovation completed - 'More electricity with the same amount of water'
- Jun 2, 2023 1:49 pm GMT
UPM Energy's Kuusankoski hydropower plant's extensive renovation project has been completed, except for some finalisations, and the plant is in commercial use.
With the overhaul and modernisation that started in 2019, the efficiency of the power plant improved by about six percentage points to 94% and the turbine capacity increased by 19% to about 37 MW. The plant's average annual energy production will increase from 180 GWh to approximately 195 GWh.
In practice, we are now able to produce more electricity with the same amount of water. All three turbines at the power plant have been renewed and the generator units have been modernised. We also renewed the automation and protection systems and one of the power plant's main transformers. The power plant's own backup power system was also renewed to make it more efficient,' says
The Kuusankoski hydropower plant is located at the River Kymi in Kouvola,
Modern hydropower technology is significantly safer for the environment. As an example, the amount of hydraulic oil in the plant has been significantly reduced with the high-pressure turbine control system,' Pollari notes.
Hydropower balances the volatility of solar and wind power
Renewable forms of energy are growing rapidly in
Balancing power is needed to stabilise the grid, and with the new automation system, the production of balancing power is now even more efficient,' Pollari explains.
Electrification of the society is advancing at a rapid pace due to urbanisation and the reduction of fossil emissions. Hydropower contributes to the ever-growing need for low-emission electricity and self-sufficiency.
