The project company, Ilmatar Kotaselkä Oy, owned by Ilmatar Energy Oy, is planning to implement a wind power project with a nominal capacity of approximately 180 MW in the Kotaselkä area of Yli-Ii, Oulu, Finland. The project area is located approximately 2.5 kilometers south of Yli-Ii town and about 34 kilometers northeast of Oulu city center.

In the Kotaselkä area, there are plans for up to 18 turbines with a maximum sweep height of 350 meters. The final outcome of the planning will be influenced by factors such as the zoning and Environmental Impact Assessment (EIA) studies, opinions, statements, and stakeholder discussions.

The area has been designated as a potential wind turbine area in the draft of the ongoing North Ostrobothnia Energy and Climate Phase Regional Plan (tv-3, number 513). The project has received a favorable opinion from the Finnish Defense Forces.

Current Status

The Urban Technical Committee of the City of Oulu approved Ilmatar’s zoning initiative for wind power area zoning on January 17, 2022.

On September 19, 2023, the Urban Technical Committee of the City of Oulu, in section 424, approved the participation and assessment plan for the Kotaselkä wind power park and decided to announce the initiation of zoning as well as the availability of the participation and assessment plan. The participation and assessment plan (OAS) for the Kotaselkä wind power project will be available for viewing from October 3 to November 1, 2023.

In parallel with the Kotaselkä project’s wind power partial master planning, an Environmental Impact Assessment (EIA) process has been initiated in accordance with the EIA Act, with the North Ostrobothnia ELY Centre acting as the coordinating authority. The North Ostrobothnia ELY Centre has made the environmental impact assessment program (EIA program) for the Kotaselkä wind power project available for viewing from October 3 to November 1, 2023.

Current Events

A joint public event for the Kotaselkä wind power project’s partial master planning OAS phase and the EIA program phase will be held on Tuesday, October 17, 2023, from 17:00 to 19:00 in the auditorium of the Kierikkikeskus (Pahkalantie 447A, Yli-Ii, Oulu).
