Swedish energy company, Vattenfall, has announced plans to upgrade four existing hydro power stations in Sweden to increase their capacity by an additional 730MW. The company has begun pre-studies to prepare for upcoming investment decisions for each project, with works expected to be carried out from 2026 and completed by 2032.
One of the projects includes the renewal and reinstatement of a hydro power unit that is currently out of operation at the Harsprånget power station on the Lule älv river, which could provide up to 110MW of additional capacity. A decision to invest in this site is planned for 2024, with commercial operations anticipated by 2026.
Additionally, Vattenfall plans to increase water flow and generation at the Porjus power station on the Lule älv river in Norrbotten to deliver a potential capacity of up to 80MW. A final investment decision is expected in 2026, with commercial operations due before 2031.

Furthermore, the company is conducting a pilot study to investigate the reinstatement of the Juktan power station on the Storjuktan lake adjacent to the Umeälven river in Västerbotten. The site could become a pumped storage plant with a capacity of up to 380MW. A decision to invest in the site is planned for 2027, with commercial operations starting in 2031.
Vattenfall is also planning to install a fourth unit at the Messaure power station on the Lule älv river with a capacity of up to 150 MW. A final investment decision is planned for 2028, with commercial operations earmarked for 2032.
Johan Dasht, head of hydro power operations in the Nordics, said: “It is truly a pleasure to announce our plans to build new hydro power in Sweden. If these projects are put in motion, it will mean a substantial increase in output when we need it the most. This is necessary to meet the rising demand for fossil-free electricity, which is a must if we are to reach our climate goals.”
Dasht went on to explain that hydro-power reservoirs are Sweden's green batteries and by adding new flexibility and balancing capabilities, they are paving the way for a greater proportion of wind and solar power in the electrical system. “Vattenfall strives to continue developing hydro power to meet the increased demand. Its great capacity to store energy in dams and its capacity for control are enormous assets. In the pre-studies, we will analyse the consequences on the environment, technology and the impact on local stakeholders. And, where appropriate, we will also consult with those affected.”
These projects are a significant step towards Sweden's goal of becoming a fully fossil-free society by 2045. With hydro-power playing a crucial role in the country's renewable energy mix, Vattenfall's investments will contribute to meeting the growing demand for clean electricity and help combat climate change.
