The country’s demand for electrical energy is mostly covered by hydropower and nuclear power. There are about 16,301 MW of total hydropower capacity installed, producing some 63.9 TWh/year or around 40% of the national output. The bulk of the more than 2,000 hydropower plants in Sweden are located on the four main rivers – the Luleälv, Indalsälv, Umeälv and Ångermanälv.
In order to become independent of fossil fuels in all sectors the government has announced a strong commitment to the development of sustainable energy resources. Under these plans, by 2040 Sweden’s entire energy supply is to be 100% based on renewable energies. A major focus will be onshore wind but this intermittent energy will be balanced by existing hydroelectric power plants, as well as stronger networking with neighboring countries. In 2017, the country also established a goal of being fully greenhouse gas-neutral by 2045 as set out in its Climate Protection Act.
As the average age of the hydropower plants in Sweden is 45 years, there is an extensive market for service and rehabilitation to make them fit for the new operational regimes and grid demands associated with large volumes of variable output renewables.
