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.

The pumped storage power plant at Ailangantunturi: Environmental impact assessment (EIA) procedure

We have begun the EIA procedure concerning the pumped storage power plant and power line planned to be established at Ailangantunturi. The procedure aims to reduce or fully prevent any adverse environmental impacts as well as improve everyone’s chances of receiving information about, taking part in and having an influence on the project. All parties affected by the project can participate in the EIA procedure.

We work in close cooperation with the authorities. Besides the statutory EIA procedure, we established a monitoring group for the project. This will ensure that our stakeholders are informed about the project and the progress of the EIA.

During the spring, we have created an EIA programme for the pumped storage power plant and power line project at Ailangantunturi. The programme is a plan outlining how the assessment of the project’s environmental impact will be carried out. The EIA programme provides a preliminary description of the present situation in the area, identifies the possible impacts of the project, and describes how the impacts will be assessed in more detail.

On May 7, we submitted the EIA programme to the Lapland ELY Centre, which acts as the coordinating authority. Opinions and statements on the EIA programme could be submitted to the Lapland ELY Centre until 14 June. We presented the EIA programme at a public event in the Council Chamber of the Kemijärvi City Hall.

Once the programme and natural resource inventories have been completed, Kemijoki Oy will create an EIA report that includes all natural resource inventories and research conducted in accordance with the EIA programme. We will present the EIA report at a public event in early 2025.

The assessment of environmental impacts has already started. We will assess the impacts on, among others, surface waters and water management, soil and bedrock, groundwaters, fish stock and fishing, vegetation, wildlife and other natural assets in the area, conservation areas, reindeer husbandry, climate, air quality, and urban structure. The need for separate assessments will be determined at the hearing stage of the EIA programme.

The EIA procedure is planned to be completed during the early summer of 2025.
