Overview
Filisur is a 65 MW hydroelectric power plant located in Switzerland. It operates as a run-of-river facility, contributing to the country's renewable energy mix.
Filisur is a hydroelectric power plant located in the Swiss Alps, near the town of Filisur in the canton of Graubünden. With a capacity of 65 MW, it is a medium-scale facility within Switzerland's extensive hydropower network. The plant harnesses the flow of the Albula River, a tributary of the Rhine, and operates as a run-of-river installation, meaning it generates electricity without significant water storage. The plant utilizes Francis turbines, a common technology for medium-head hydroelectric projects. Switzerland's mountainous terrain and abundant water resources make hydropower the backbone of its electricity generation, accounting for over 60% of the national total. The facility operates under Swiss federal water regulations and is subject to the Swiss Energy Strategy 2050, which promotes renewable energy expansion and modernization of existing plants. Filisur plays a role in providing clean, renewable electricity to the Swiss grid, supporting the country's goal of phasing out nuclear power and reducing carbon emissions. Its location in a sparsely populated alpine region minimizes local environmental impact, though it contributes to the broader ecological management of river flows and aquatic habitats.
Environmental context
Hydroelectric power generation in Switzerland is generally considered low-carbon, but it can affect local aquatic ecosystems through altered river flows and sediment transport. The Filisur plant, as a run-of-river facility, has a smaller ecological footprint than storage-based hydropower, as it does not create a large reservoir. However, it still requires careful management to maintain fish migration and riverine habitat health, in line with Swiss environmental regulations.
