The Kihniö Municipal Board decided on 23 January 2023, Section 13, to make the material and draft of the Lylyharju wind power sub-general plan preparation phase publicly available. The Lylyharju wind power sub-general plan was available as a draft from 1 March to 14 April 2023. 11 statements and 3 opinions were received on the draft sub-general plan. The plan author's responses to the statements and opinions have been provided, and are attached to the plan description.

At the proposal stage, the number of power plants in the plan solution is six. Compared to the draft stage, one power plant site has been removed and the location of the power plants has been revised. In particular, the number of power plants and the placement of the power plants have been influenced by taking the protected golden eagle into account. Based on the modelling, the power plant placement indicated in the plan will not have significant impacts on the golden eagle.

The entire plan area has been designated as an M-1 area, which allows for the continued use of agriculture and forestry as usual. The plan has designated TV areas, where one wind turbine may be built each. The total height of the turbines may not exceed 290 m above ground level. The exact location of the turbines will be determined in connection with the building permit. The internal electricity transmission of the wind power area is indicated as an indication along the service roads.

During the planning proposal stage, the markings of the nature value areas have been specified. The Iso Ristineva and Lylyneva areas have been designated with a luo-2 area boundary in accordance with the mire protection programme area. The extent of the planning area has been revised during the proposal stage. The planning area has expanded slightly in the south-eastern part from the solution in the draft stage. With the expansion, the calculated 40 dB noise area is located entirely within the planning area.

The Elonkirjo and Energy Phase Regional Plan has designated the Lylyharju area as a wind energy production area. The current regional plan markings have been taken into account in the placement of the power plants.

Land use in the plan area is forestry, disused peat production areas and arable land. The nearest urban settlement from the power plants is in the village of Kihniö, approximately 10 kilometres to the southeast. No residential or holiday buildings will be located in the plan area. The nearest residential buildings are located approximately 1,5–2,0 kilometres from the power plants on the eastern side of the plan area in Ratinkylä. The nearest holiday buildings are also located approximately 1,5–2,5 kilometres from the nearest power plants on the shore of Lake Iso Madesjärvi.

The main impacts on land use during the operation of the wind farm primarily concern the transformation of undeveloped forestry and agricultural areas into energy production areas and new road areas. The impacts also partly affect the recreational use typical of forestry areas. The impacts are very long-term in terms of the project's life cycle, but they affect a relatively small area of ​​the planning area.

There are no community structure or land use development needs in the planned area or its immediate vicinity that would not be compatible with wind power construction. The Lylyharju wind power park will not have a significant impact on the community structure of the municipalities in the project area.

Based on the power plant location, the noise impacts of the wind power project will remain below the guideline values ​​set out in law and regulations in relation to constructed residential and holiday buildings and planned unconstructed residential and holiday building sites. With regard to lightning, both constructed and unconstructed planned building sites remain outside the lightning impact area.

When seen in the immediate vicinity of the power plants, the large size of the power plant can be perceived very concretely. In that respect, the change in the landscape is great. However, the areas in question are not visited very often. In addition, the landscape of the area is quite ordinary and the sensitivity is quite low, so the impacts on the landscape will be quite minor.

The plan area does not include any nationally, regionally or locally significant landscape areas or built cultural environments that could be subject to landscape impacts. The immediate area of ​​impact of the wind turbines includes some residential buildings along Ratikyläntie in the east and holiday homes on the shores of the southern part of Iso Madesjärvi in ​​the northwest. Some of them are located in closed environments so that they would not have a direct view of the wind turbines. Some of the buildings or their yards and surrounding areas could have a few turbines visible.

On the outer border of the local area, there is one provincial cultural landscape in the southeast called the Korhoskylä cultural landscape. In the cultural landscape, power plants may be visible in a very small area along Ratikyläntie, approximately 600 meters away, in an open field, near the Lylyharju Kihniö power plants. Outside the local area, based on the view area analysis, power plants would be visible mainly in the water areas of Korhosjärvi and part of the southeastern shorelines. A visual image made of Korhosenniemi shows that power plants may indeed be visible, but when visible, they are not very dominant, and in addition, vegetation strongly obscures the visibility of the power plants.

In the intermediate area, the power plants would be best visible over the wider lake basins and their shores. At Kankarinjärvi and Kuivasjärvi, the power plants would be more widely visible over the open backs of the lakes and the more southern shores. At Linnanjärvi, a narrower view sector would be formed over the southern part of the lake and a short distance along the southern shore. Lake Nerkoonjärvi is further away, and it has a more irregular shape and is narrower in places, so that the view areas formed over it are more fragmented than at Kankarinjärvi and Kuivasjärvi.

Anti-aircraft lights change the character of the landscape, especially in dark and clear weather, when the lights stand out clearly high in the air, above the treetops, where there are no other light sources. Especially in the early stages of a wind farm's life cycle, a landscape that is used to seeing without any light sources can be experienced as unsettling.

After the operation is completed, the wind turbines can be dismantled and removed in their entirety. Regarding the foundations and cables, it must be decided whether the structures will be left in place or removed. If all structures are removed, the project will not have any impacts on land use after decommissioning. If the foundation slabs are left in place, the impacts can be reduced by landscaping.

No ancient remains were found in the project area. In Madesluoma, located in the northern part of the project area (on the Kurika side), there is a dam and a riverbed possibly related to a mill, which was defined as another cultural heritage site. On the eastern side of Lylyneva (on the Kihniö side), the remains of a fairly young forest hut were found, which was defined as another site. During the inventory of the electricity transmission route, one grave pit and two tar pits were discovered, which were defined as fixed ancient remains. The ancient remains and tar pits will be taken into account in the more detailed planning of the project and will be excluded from the construction measures.

The impacts on forest species at the construction sites will be permanent for the duration of the wind farms' operation. However, they are assessed as minor overall, as the area of ​​forest land affected by the construction is small in relation to the entire demarcated project area. The impacts will mainly affect barren and regionally and nationally very common forest habitat types.

Monitoring of the bird impacts of constructed wind farms over several migration seasons conducted in recent years has found that there are only minor impacts on bird migration routes, and the impacts are mainly manifested as local changes within migration routes as birds try to avoid wind farms.

The most significant bird values ​​of Lylyharju are concentrated in the Iso Ristineva and Lylyneva areas, which have been identified as, among other things, regionally valuable bird areas. These areas will not be directly affected by changes, but noise and other disturbances during the construction phase may still temporarily drive away breeding birds from the area or weaken the nesting success of birds nesting in the area during the construction years.

Based on the modelling, the annual probable flash impact will be at most within the Swedish guideline value of 8 hours for all residential and holiday homes in the area. The daily probable flash time will also be below the Swedish guideline value of 30 minutes for all homes in the area.

Due to the change in the Building Act, the municipality's building regulations must be updated to reflect the changed legislation by the beginning of 2027. The municipality of Kihniö has kept rThe participation and assessment plan for the renewal of the building regulations will be available for viewing in late 2024. The work has been delayed due to personnel changes in the technical department. At the meeting, building inspector Raisa Karintaus and land use expert Pasi Lappalainen will present the status of the renewal of the building regulations.

The planning areas are located on different sides of Lake Nerkoonjärvi in ​​Kihniö. There are existing road connections to the planning areas. The commencement of the planning work was announced on 10 December 2024. The participation and assessment plan and the draft plan were on display from 11 December 2024 to 15 January 2025.

The aim of the coastal zone plan being prepared is to update the land use of the area's holiday construction sites to meet current needs and current use. The construction sites in the plan area will be assigned permitted building rights in accordance with the municipal building regulations. Some of the planning areas have coastal zone plans that came into force at different times. Some of the planning areas are areas without coastal zone planning.

The Kihniö Technical Committee has discussed the plan proposal dated September 9, 2025 at its meeting on October 20, 2025, Section 79. The Committee decided to return the matter for re-preparation.

The following changes have been made to the planning proposal material based on the decision of the technical committee:

• A sauna building designated for an agricultural and forestry area has been removed from the planning map.

• Technical corrections have been made to the proposed regulations.

The plan designates a total of 10 construction sites, eight of which are designated as holiday home construction sites and two as detached single-family homes. Of the eight designated leisure construction sites, seven are already built. One zoned but unbuilt leisure construction site will be moved south from the east bank in the same property area.

The planning areas are mainly forested courtyards of built holiday homes. There are no known natural or landscape values ​​in the planning area. A nature study has been prepared for the area during the spring and summer of 2024.

An archaeological inventory has been prepared for the area in connection with the planning work. The inventory discovered a fence-like stone mound on top of a rock outcrop on the southeastern edge of Kivelänniemi. The mound is likely related to a field/meadow area located in the area on the 1804 division map and the 1960 basic map. The stone mound is proposed as another cultural heritage site.

The building sites in the plan area are mainly already built, and the plan mainly only allocates a small amount of additional building rights to already completed building sites. New buildings or extensions may be visible in the landscape to some extent when completed, but the general provisions of the plan have sought to guide construction in such a way that the buildings adapt to the landscape in terms of colour, facade materials and proportions, and that sufficient trees are preserved on the construction site. The plan is therefore not assessed to have a significant impact on the landscape structure or natural conditions of the area.

The technical director presents the financial situation at the meeting.
