Finland’s largest solar farm is planned to be built in South Ostrobothnia
The economic competitiveness of solar power has improved over the last few years, and this trend is expected to continue. In 2020, EPV Energy (EPV) started planning its first industrial-scale solar power project.
After looking into the optimal location for the solar farm, EPV decided to build it on a peat production area in Heinineva, Lapua, where peat production is estimated to come to an end in 2022. The Heinineva area is large and open and almost unimpeded by shadow. During the year, the project obtained a legally valid decision on the need for planning, and permit applications for the future use of the area were submitted.
The area offers an excellent potential site for solar power generation.
In planning the solar power plant in Lapua, EPV is making use of the data collected at the EPV Alavus solar power measuring station.
If implemented, the Heinineva solar power plant will be the largest in Finland by far. Key figures for the planned solar farm:
- Area size 140 hectares
- Plant’s total output 100 MWp
- About 200,000 solar panels
- Output per panel 400 Wp
- Plant’s average output during its life cycle approximately 90–95 GWh
- Length of panel mounts 100-150 km
If implemented, the project is estimated to be completed later in the 2020s. Whether the solar farm becomes a reality depends on the competitiveness of the solar cell technology at the time of building, the cost-effectiveness of construction and the shareholders’ investment needs.
