6 FAQs about [Slovakia seasonal energy storage]
Is there a regulation on energy storage in Slovakia?
It is not directly addressed in EU Directive 2009/72/EC, but nonetheless a specific regulation on electricity storage is foreseen (Ministry of Economy of the Slovak Republic 2018, 61). Accordingly, energy storage in Slovakia is taking its first steps. Similar to the EU, it still lacks a precise national regulation.
Does Slovakia need a decentralized electricity generation system?
In this European setting, Slovakia is largely dependent on its domestic production of nuclear energy and the import of primary energy sources to meet its primary demand. The implementation of decentralized electricity generation then becomes a priority.
Why is pumped storage important in Slovakia?
Coupled with pumped storage technologies, this popular source in Slovakia is regarded as the key to lower disruptions in the national transmission network ( International Energy Agency, ‘Energy Policies of IEA Countries: Slovak Republic’ (2018 review), 123.).
What energy sources does Slovakia rely on?
However, Table 1 also shows that Slovakia is extremely dependent (nearly 90% according to its own government) upon imported primary energy sources, especially crude oil and natural gas (Calculated as a result of official estimations of nuclear fuel (100%), natural gas (98%), oil (99%) and coal (68%).
How much electricity is lost in Slovakia?
As to distribution losses in the network, Slovakian figures are fairly positive: the last available report showed that 0.98% of the total electricity transmitted was lost (International Energy Agency 2018, 69).
How can EV development contribute to Slovakia's energy policy?
Further, combining the EV development with integration efforts of renewable energy generation (Daňo and Róbert 2018e) would facilitate a more integral design of Slovakia’s energy policy. Slovakia does not have a regulatory framework to specifically address demand response mechanisms.
