Hydropower in Värmland (SE)

Location: River Klarälven Värmland, Sweden

Case study lead: Länsstyrelsen Värmland - Värmland County Administrative Board

Constituent systems: Catchment, city and infrastructure networks

In Värmland weather trends connected to climate change are already visible: higher temperatures, more rainfall (especially during autumn and winter), less snow in winter and thus less snow melting in spring. This results in changes in the flow of water, higher in autumn and winter and a longer period with lower between April-September. The need for electricity changes (i.e. increased demand for summer cooling). The way the current system is being operated is not climate change proof. This case study will focus on how to regulate water flows, how to meet shifting electricity needs and how to do this without the currently common spring floods.

In this study it will also be important to take into account and develop biodiversity in and surrounding the river basin and catchment area. A digital model for water regulation will be created and used to show the impact of different climate scenarios on the flow in the river. In this case, flood risk management, energy production and energy use by society and industry are closely intertwined. Climate adaptation will require adaptive management of hydroelectric power plants, a better understanding of the system and a close dialogue with all different stakeholders in order to increase the resilience of communities and industry. This case will involve sectors such as energy supply and flood risk management, and stakeholders will include local authorities, hydroelectric power companies, land owners and citizens.
