Slovakia unlikely to resume wind and solar power construction

Construction of solar and wind power plants in Slovakia will probably not resume. A study that the experts of the Slovak Technical University in Bratislava elaborated for the Slovak Electricity Transmission System (SEPS) shows that the Slovak power grid is currently not ready for construction of not only renewable sources of energy, but also for other new energy sources. According to the analysis, Slovakia will first have to increase the transmission capacity of its transmission network.

Construction of solar and wind power plants in Slovakia will probably not resume. A study that the experts of the Slovak Technical University in Bratislava elaborated for the Slovak Electricity Transmission System (SEPS) shows that the Slovak power grid is currently not ready for construction of not only renewable sources of energy, but also for other new energy sources. According to the analysis, Slovakia will first have to increase the transmission capacity of its transmission network.

"It is impossible until the end of 2016, or until the time of a further increase of transmission capacity in the profile Slovakia - Hungary, to consider any further construction of renewable energy sources, not even in the scope of the remaining balance from the National Action Plan of the Slovak Republic. It should also be seriously considered what other sources of electricity than renewable sources can be allowed to be built on the territory of Slovakia, in addition to the still unfinished blocks in Mochovce," says the study as quoted by the SITA newswire.

The results of the study indicate that increasing installed capacity by renewable as well as other energy sources in the Slovak power grid without adequate transmission system development can pose "a serious threat to the safe and reliable operation of the transmission system." If Slovakia decides to follow conclusions from the study, it is likely to be unable to fulfil its commitment as a member of the European Union set out in the approved National Action Plan for Energy from Renewable Sources.

"The Economy Ministry should therefore revisit the approach to issuing certificates for the construction of new electricity resources and also review the already valid certificates ... so as to fulfil the amount of installed capacity of renewable energy sources set out in the National Action Plan and to respect the commitment of Slovakia," says the study. In addition to increasing transmission capacity in the profile of Slovakia - Hungary, the firm SEPS should focus on increasing capacity in the profile of Slovakia - Ukraine.

SEPS is currently intensively analysing possibilities for how to eliminate causes that have a negative impact on decisions about connecting any new power resources to the grid. Construction of wind farms in Slovakia was suspended at the end of 2009. SEPS has since then not issued a single positive opinion for the purpose of obtaining a certificate for the construction of a wind power source from the Economy Ministry. Later, the same applied to solar power plants. SEPS considers solar and wind power an unstable power source with large fluctuations in production.
