The Czech Energy Regulatory Office (ERÚ) has outlined changes to tariffs for high-voltage (VN) and very-high-voltage (VVN) networks, due to take effect in January 2027. The aim is to use the energy networks more efficiently, reduce the need for investment and limit increases in regulated charges.
The changes will affect around 25,000 entities. Consumers currently pay for reserved capacity and for exceeding it. Under the new system, charges will be based on reserved input capacity and maximum power drawn.
ERÚ chairman Jan Šefránek said the changes could free up as much as 3,300 MW of capacity, or about 15% of the networks’ total capacity. Some consumers reserve capacity without using it. The regulator estimates that more efficient network use could save 2–3 billion Czech crowns a year.
