The Slovak Republic needs to source 14% of its energy from renewables, up from 6.7% in 2005, if it is to meet its targets under the EU renewable energy directive. According to the country's draft energy policy, the capacity is there to exploit. The government estimates total potential for renewables would be for 15% of overall energy demand.
Renewables, it says, could generate 43 TWh a year. The sector currently supplies 5.2 TWh, accounting for 16% of household consumption. As now, most of its renewables capacity would come from hydro, it says, with wind accounting for 0.6 TWh at most, or 14%. This will come from around 100 MW, all currently under development. The technical potential according to the European Renewable Energy Council is for 930 MW of wind by 2020.
The Slovakian government's draft policy, published last year, assumes the use of 0.5-1 MW turbines to attain the 0.6 TWh. If 2 MW turbines are used instead, generation potential from wind would rise to around 1.14 TWh. "Only areas with the best wind conditions are suitable for the effective utilisation of wind energy and these are only in a small fraction of the territory of the Slovak Republic," the draft policy document says. "The installation of wind power plants in national parks is impossible," it adds. In total electricity terms, it is aiming for 19% to come from renewables in 2010, rising to 24% in 2020.
Policy to support development includes giving priority for renewables regarding transmission, distribution and supply and a system of fixed prices for renewables power. Rates for wind in 2008 were EUR0.051-0.089/kWh, but so far just 5 MW has been installed.
