Czech Republic expects boom: New laws bring battery revolution!
The Czech Republic is facing a boom in battery storage power plants thanks to new laws. Energy providers are planning large projects as demand grows with rising energy prices.
Czech Republic expects boom: New laws bring battery revolution!
In the Czech Republic, the energy industry is facing significant change, which will be triggered by the upcoming amendment to the Renewable Energy Act (Lex OZE III) in October 2025. To date, battery storage power plants have played a subordinate role in the national energy system, which is primarily due to outdated legislation. But with the new law, energy providers expect a boom in battery storage power plants that has the potential to radically change the country's energy storage landscape.
Jan Fousek, Secretary General of the Association for the Accumulation of Energy (Aku-Bat CZ), predicts a trend towards large solar power plants and large storage facilities. Battery storage power plants with many thousands of megawatt hours have already been applied for, and energy company MND is planning to build a large storage project near Břeclav with a capacity of 31 megawatt hours.
Growth and future projects
In addition, MND has announced further projects in Orlová, Mušov, Bruzovice and Hodonín. The company also operates corresponding projects in Germany and is aiming for a total target capacity of over 400 megawatt hours. Half of these are expected to go into operation next year. The parastatal energy company ČEZ has already built large-scale electricity storage facilities in the past and is working on other projects, including a battery storage facility with 200 megawatt hours of capacity at the Chvaletice power plant, which is considered one of the largest in the Czech Republic.
Battery storage is particularly popular with private households and companies that produce their own electricity. High energy prices combined with falling feed-in prices have extended the capital return period, but flexible users can save money by using storage.
The position of the Czech Republic in Europe
The Czech Republic occupies a leading position in Europe for home storage systems. MND currently manages around 196,000 rooftop solar systems, 87% of which are equipped with storage. PRE distribuce also has 8,543 photovoltaic systems, 74% of which are equipped with battery storage, mostly with a capacity of 10 kilowatt hours. The country's total battery storage capacity was under two gigawatt hours at the end of last year, with a forecast of an increase to five gigawatt hours by 2030.
In the context of the European energy transition, the integration of energy storage is crucial. In Germany, more than half of electricity generation already comes from renewable energies, and over 90% of electricity is expected to come from wind and photovoltaic systems. This means that electricity generation becomes increasingly susceptible to fluctuations. Balancing options in the European electricity grid through storage are therefore essential in order to meet the needs of consumers.
Storage systems are referred to as the “troubleshooters” of the energy transition. They enable cost savings and optimization of the entire system. An update of the storage demand forecasts shows that large battery storage systems will become even more important by 2045, both for flexibility in the power grid and for the seasonal compensation of varying generation conditions.
The coming months will be crucial to observe how these developments will materialize in the Czech Republic and what role the country will continue to play in the European context of renewable energy and modern energy storage technologies.
