Objectives of the researchObjectives of the research
G l i d i l i S h K li i 2009− General wind power potential assessment in South-Karelia in 2009− Wind conditions are sufficient for further study− More detailled measurements necessaryMore detailled measurements necessary− Territories adequate for wind power production were pointed
− Wind measurements in three places in South-Karelia in 2009-2011− Inland wind conditions
P fit bilit f i l d i d d ti− Profitability of inland wind power production
