Hydropower accounts about 1/3 of Fortum's annual power generation
Fortum is one of the biggest and most experienced producers of hydropower in the Nordic countries. In 2010, 48% of our power generation in Nordic countries was based on hydropower. In the Nordic countries we have a nearly 4,700-MW capacity.
In 2010 hydropower accounted for a 22-TWh share of Fortum’s 53.7 TWh of power generation. The share fluctuates every year based on the hydrological situation.
Fortum has 260 fully- or partly-owned hydropower plants in Sweden and Finland. A significant share of Fortum’s hydropower capacity is generated by 211 hydropower plants in central Sweden. The plants with the largest capacity are on the Ljusnan, Indalsälven and Dalälven rivers. Fortum has 50 hydropower plants in Finland. The bulk of Fortum’s own hydropower production in Finland is located on the Oulujoki river and the waterways of Vuoksi. In addition, Fortum owns shares in Kemijoki Oy.
At Fortum we are developing our existing hydropower production in accordance with our long-term refurbishment program that aims to increase carbon dioxide-free hydropower generation capacity, energy efficiency and safety and to secure high availability of the power plants. In addition, Fortum aims to actively mitigate the local environmental impacts of hydropower production in the municipalities where it has power plants.
Today about 450 industry professionals work in the company’s hydropower businesses. In addition to its own power plants, Fortum has carried out hydropower plant and dam refurbishment projects for other energy companies in e.g. the Nordic countries, the Baltic countries and Russia.
Hydropower's important role
In the Nordic countries hydropower plays a key role in balancing the production and consumption of electricity. Hydropower plant start-up, regulation and shutdown is quick, and water stored in the reservoirs helps to balance the fluctuations in consumption. Hydropower’s role in balancing production and consumption will be emphasized in the future when an increasingly bigger share of electricity is produced with e.g. wind and solar energy.
