Survey of Energy Resources 2007
Hydropower Country Notes
The Finnish WEC Member Committee reports that a significant proportion of the natural flows suitable for power production are located in preservation areas. According to the study Volume and potential of hydropower in Finland, 7 400 GWh/yr of the technically exploitable capability (22 600 GWh/yr) is located in conserved water flows.
The same study estimates that the following amounts of small-scale (<10 MW) hydropower capacity/generation will be installed during the period to 2020:
10 MW (28 GWh/yr) in 2005-2010
20 MW (48 GWh/yr) in 2010-2015
53 MW (187 GWh/yr) in 2015-2020
The Finnish Government can aid the building and production of small-scale hydropower. In practice, investment aid has been around 20%, and it has only been granted to plants with a capacity of less than 1 MW. These plants also receive tax subsidies (€ 4.2/MWh) for the electricity that they produce.
