One explanation for the high coverage in some Norwegian municipalities is the presence of data centres located on the western coast (in Stavanger municipality and Vagsoy municipality) which benefit from free cooling from adjacent fjords and abundant access to low cost, renewable hydropower. Most are located across Sweden and in the rural parts of Denmark, Finland and Norway. The second largest group is municipalities with a value between 30% and 60% of households with high capacity fixed broadband coverage: they are mostly located in rural Norway and Finland and in northern Sweden.
