Ailangantunturi pumped-storage power plant

We are continuing the preliminary planning of the pumped-storage plant at Ailangantunturi in Kemijärvi. We are modelling and assessing the impacts of the construction and use of the Ailangantunturi pumped-storage power plant. We are estimating the effects of pumped-storage power plant on people and the environment.

Ailangantunturi pumped-storage power plant

  • Technical information

    Technical information

    Plant type: Pump turbine
    Head potential: Approx. 200 metres
    Capacity: 550 megawatts (MW)
    Number of machinery: 3

    The size of the upper storage of the pumped-storage power plant is around 1 square kilometre, while Kemijärvi works as the lower storage. The tunnel between the upper and lower storage is approximately 4−5 kilometres long and 9 metres wide. The pumped-storage plant can be connected to the existing electricity main grid at the Pirttikoski power plant.

A pumped-storage plant will boost Kemijärvi’s local economy

The Ailangantunturi pumped-storage power plant will bring new jobs already in the construction phase as well as permanent positions in the plant’s management and maintenance. The plant will also bring Kemijärvi millions of euros of income from real estate taxes, which will help to improve local and regional wellbeing. In addition, the pumped-storage power plant enables new industrial investments and makes Finland – and Kemijärvi – more attractive to companies as an investment environment.

We are in close dialogue with our local and regional stakeholders and discuss the significance, implications and progress of the Ailangantunturi pumped-storage power plant project. We will continue our dialogue, among others, with the city of Kemijärvi and land owners in the region.

Ailangantunturi pumped-storage power plant: Environmental impact assessment procedure

We have started an environmental impact assessment procedure regarding the pumped-storage power plant at Ailangantunturi in Kemijärvi and a related power line.  The aim of the environmental impact assessment procedure is to mitigate or prevent harmful impacts on the environment and improve everyone’s access to information, participation and influencing. Everyone potentially affected by the project can participate in the EIA procedure.

In addition to the statutory environmental impact assessment, we are also establishing a steering group and monitoring group for the project. This allows us to ensure that our stakeholders are informed of the project and the progress of the environmental impact assessment.

During spring 2024, we will create an environmental impact assessment programme for the Ailangantunturi project, which is a plan outlining how the assessment will be carried out. Then we will compose an EIA report, which compiles information regarding the environmental impacts of the project and its alternatives.

The EIA procedure is expected to be completed at the beginning of 2025.
