Czechia Electricity Tariff API

How a household electricity price is built in Czechia

Czechia liberalized household supply in 2006 and hundreds of licensed suppliers now compete, but the regulated half of the bill is set unusually cleanly. Rather than each network operator publishing its own price sheet, the regulator issues two price decrees a year that print every low-voltage tariff, the transmission charge and the levies as hard figures. Only three regional operators serve households at all; the several hundred other distribution licences are industrial estates, campuses and railways nested inside them.

What a household bill is made of

1. 1

   Energy

   Freely set by the supplier and not regulated. Static products quote a fixed rate per tariff class; dynamic products track the day-ahead clearing price, which is quoted in euro and so brings a currency conversion that fixed-price products avoid. There is no regulated default retail price.

2. 2

   Network charges

   Regulator-set fixed prices per operator and per distribution class, in two parts: a monthly capacity charge banded by the rating of the main breaker, and a per-kWh charge — single-rate for one-tariff classes, split into high and low tariff for the two-tariff classes used with storage heating, heat pumps, EV charging or weekend modes. The low-tariff window is set operationally by the network operator subject to a statutory minimum duration.

3. 3

   Taxes and levies

   A national transmission system-services charge levied on every kWh delivered; a small fixed monthly charge per connection point bundling the market operator’s, the data centre’s and the regulator’s costs; and a flat electricity tax. The renewables-support levy has historically been a large item, and — importantly for anyone comparing years — it was never a per-kWh charge for households but a monthly charge per ampere of breaker rating; it was moved onto the state budget and set to zero from 2026.

4. 4

   VAT

   21%, the standard rate. Heat and cooling sit in the reduced band but electricity does not, so the reduced rate must not be inferred from the heat rate.

Regulation shaping the price

• The regulator must publish, by 30 November each year, the price decrees fixing every regulated component for the following calendar year — one for low voltage and one for higher voltages plus the national levies.
• There is no regulated default tariff. The statutory backstop is a supplier-of-last-resort per distribution territory, which must take over a failed supplier’s customers for up to six months at a regulator-capped price.
• Dynamic-price contracts are recognised in statute, with a one-month unilateral termination right for the consumer and a duty on the supplier to explain the pricing formula in writing beforehand. They are legally conditional on interval metering, which is the practical brake on uptake.
• New household solar has no classic feed-in tariff: surplus is either sold to a trader at a market-linked price or, increasingly, moved through the statutory energy-sharing scheme settled in 15-minute intervals.
