Hydropower – renewable and clean energy Hydropower is the most important form of renewable energy in the Nordic countries. It is a steady source of power that produces no CO2 emissions. And with only water as an input, the low operating costs of hydropower stabilise the price of electricity for everyone. ForTheDoers Blog Batteries and hydropower turbines get longer life in Sweden Read more Low emissions CO2 free Hydropower helps fight climate change because it doesn’t produce harmful emissions. Fuel source flexibility Flexible Changes in demand can be met by increasing water flow to generate more electricity. Renewable Renewable Water behind a dam is a renewable energy source that does not need to be purchased. Reducing our footprint A clean-energy future means generating electricity without producing CO2 emissions. For us, hydropower provides much-needed electricity while also playing an important role in minimising our carbon footprint and helping mitigate climate change. Extra energy More production capacity is needed during times of peak power demand. While coal-fired electricity could be used to fill the gap, hydropower and water flow management offers enough flexibility to meet changes in demand without increasing CO2 output. Inexpensive to produce The operating costs of hydropower are very low. Only water is needed to generate power and because the water flow is renewable and not subject to market-based pricing, hydropower helps keep the price of electricity lower because it is relatively inexpensive to produce. 8,439 MW of power capacity 32.5 TWh of electricity produced First trout have been transferred upstream over the Leppikoski hydropower plant in Finland – Leppikoski Fishheart inaugurated Read more The River Clean-Up – contributing locally to cleaner rivers Read more Reports and presentations Case Study Eldforsen Hydroelectric Power Plant Circular economy Environmental approach We care about the environment around our power plants Climate and resources Environmental projects We go above and beyond the environmental standards for owning and operating a hydro plant Hydro power Get to know our Hydro power plants See all hydro power plants FAQ - Hydropower What is hydroelectric power?
