Czechia in detail
What the national rules say, with the legal texts.
Czechia regulates data centres in section 9c of Act 406/2000 on energy management, in force since 1 January 2024 and amended from 1 August 2025. Operators of data centres above 500 kW report to the European database by 15 May each year and tell the Ministry within 2 months of reaching 500 kW. Builders and owners of centres above 1 MW must use the waste heat, unless that is infeasible or costs exceed benefits. Building such a centre, or raising its power by more than 25 percent, needs an energy assessment unless the waste heat is used. Existing centres above 1 MW have until 31 December 2026. Fines reach 5,000,000 CZK.
