The project operator is Piipsan Tuulivoima Oy.
The project area is located in the eastern part of the city of Haapavesi, bordering the municipal boundaries of Kärsämäki and Siikalatva.
The formula for the Piipsa project was approved by Haapavesi City Council in February 2021. The formula has space for 39 wind farms with a maximum height of 300m. The formula has been appealed to the Administrative Court. The aggregate needed to build the project is to be mined from the Siikaniemi area. In connection with the extraction of aggregates, an EIA process is currently underway. In December 2021, ELY issued a reasoned conclusion on the environmental impact program. The EIA report will be completed during 2022.
