The Gårdskulla solar park is an impressive renewable energy project. The Gårdskulla solar project is in the project development phase and the company Gårdskullan Aurinkovoimala Ky is responsible for the implementation of the project.

Gårdskulla solar park is 100% owned by the funds managed by Taaleri Energia. Taaleri Energia is a Finnish renewable energy fund manager with one of the largest dedicated renewables investment teams in Europe. The team manages a portfolio of wind, solar and battery storage in Europe and the US.

The Gårdskulla solar park project area is located in Uusimaa, in Tyyskylä in Siuntio , about 9 kilometers southeast of Lohja and about 5 kilometers northwest of Siuntio municipal center. The project area is a total of about 150 hectares of land that is mainly used for agriculture in its current state, of which the space requirement for the panel fields, service roads, power station, energy storage and other structures planned in the project is about 93 hectares. In order to implement the project, a site plan will be drawn up for the area. The project's zoning initiative was approved by the municipality in November 2024, and the participation and evaluation plan will be available in spring 2025. In the project area, there are two known ancient remains areas, which are delimited outside the project planning. Kirkkojoki, a part of the Siuntionjoki Natura 2000 area, crosses the project area, around which a natural protection zone of about 20–30 meters will be left in the project. The project area is located in a nationally valuable landscape area, which is taken into account in the design of the solar park.

Gårdskulla solar park will be equipped with approximately 280,000 solar panels with an east-west monitoring system upon completion. The power fed into the grid by the solar power plant is about 60 MW, and the planned peak power of the power plant is about 72 MWp. The power plant will be connected to the main grid through the Virkkala-Espoo 110 kV power line connection that crosses the project area. The solar power plant is expected to produce 72 GWh of electricity per year, which meets the electricity needs of thousands of households and businesses. The park will produce a total of approximately 2,500 GWh of clean energy during its predicted 35-year life cycle. With the energy produced by the project, it would be possible to drive an electric car up to 12 billion kilometers. When realized, the project will be a significant employer in the area, creating up to 290 person-years of work due to annual maintenance work for at least 30 years.

To ensure the sustainability of the project, it is being evaluated if an EIA is required for the project, for which a nature study, an evaluation for the Natura 2000 study, a storm water study, a landscape study and view area analysis, as well as archaeological studies have been carried out in the area. Welado Oy, in cooperation with its subcontractors, has been responsible for project development and the implementation of studies. The project has received a decision from the ELY Centre for Uusimaa that the EIA procedure is not necessary for this project. Preliminary negotiations have been held with the municipality of Siuntio, ELY Centre for Uusimaa and the Western Uusimaa Museum regarding the implemention of the project.
