⏱️ Fixed price or dynamic (hourly) electricity contract in Slovakia: which is right for me?

The short answer

A fixed price stays the same for an agreed period. A dynamic price follows the wholesale market hour by hour, so it can be cheaper when you shift your use, and more expensive at peak times.

📜 The rules in Slovakia

Fixed and dynamic contracts

Slovak law knows both: a fixed-price contract for a fixed term and a dynamic-price contract whose price follows the day-ahead and intraday markets. A supplier with more than 100,000 supply points must sign either one if you ask, meet its terms and, for a dynamic price, have a smart meter; a refusal must be justified.

  • Before you sign a dynamic-price contract the supplier must explain in writing how the price is formed, warn you of the benefits and risks, and tell you that a smart meter is needed and is not always installed free of charge. (static.slov-lex.sk)
  • A fixed-price fixed-term contract you ask for must run at least 12 months; the supplier must warn you of its benefits and risks and that a change of supplier before it ends is not possible. (static.slov-lex.sk)
  • Every contract must say whether the price is fixed, dynamic or set in another way, and what one-off payments, extra services or discounts apply; the supplier must also explain the benefits and risks of both types on its website and in its shops. (static.slov-lex.sk)

🪜 Step by step

  1. Look at how you use energyA dynamic price suits people who can move use to cheap hours, for example with an electric car, a heat pump or a timer. It needs a smart meter.
  2. Check what is on offerSee below what the rules in Slovakia say about fixed-price and dynamic contracts and who has to offer them.
  3. Read the risks and the termsBefore you sign, the supplier must explain the costs and risks of a dynamic contract. Check the notice period and any exit fee.
  4. Review after a few monthsCompare your bills with what a fixed price would have cost. You can switch again under your contract terms.

❓ Questions

Is a dynamic contract cheaper?

Only if you use a lot of power when prices are low. At peak times it can cost much more than a fixed price.

Do I need a smart meter?

Yes. Hourly prices need a meter that records your use per hour or per quarter hour.

Can a fixed price still go up?

Normally not during the fixed period, but taxes and network charges can change. The rules for Slovakia are on this page.
