A change in the Energy Act of the Czech Republic has increased the limit for mandatory licenses for generating electricity from 50 kW to 100 kW. The change applies to solar installations that produce electricity for direct consumption.
The threshold for obtaining a mandatory license for electricity generation in the Czech Republic has been raised from 50 kW to 100 kW, Czech energy -regulating office Energetický Regulační úřad (Erú) has confirmed.
This has been the second time in recent years, the threshold has risen after the limit was increased from 10 kW to 50 kW in 2023.
The change applies to solar energy plants that produce electricity for self-consumption or only for free sharing. Ergo chairman Jan Šefránek confirmed that a license is still required for power plants used for business purposes, or if another power plant is connected to the same point of consumption, regardless of the capacity of the system.
“A license is also required for producers who receive support for their power plants under the law on supported energy sources,” Šefránek added.
The newest change in the Energy Act of the Czech Republic also introduces new licenses for electricity storage. If the storage device is connected via a production factory and the installed capacity is no more than 20% higher than the capacity of the connected factory, it does not require a separate license. If multiple devices for electricity storage are connected to a one -generation factory, the limit collective applies.
Šefránek said that in the future it will be necessary to considerably revise the entire system of recognized activities in the Energy Act “so that it better matches the new environment in which the energy sector is located.”
“The original meaning of publishing licenses has already been surpassed in many cases,” the chairman added.
The Czech Republic used 357 MW in the first half of 2025, making the cumulative solar capacity on more than 4.8 GW, according to figures from the Czech Solar Association Solární Asociace.
Earlier this month, the Cyber Security Office of the Land warned of the potential security threat of Chinese solar sides.
