The energy crisis of 2021 to 2022, driven by unprecedented price spikes on power exchanges (such as EEX), marked a turning point for the Czech energy market. The Energy Regulatory Office (ERO) of the Czech Republic experienced a dramatic shift in its role as it operated almost as a “crisis hotline”. This environment created the necessity to introduce the new measures and legislative tools that make ERO more efficient and effective in its oversight activities. One such measure is the introduction of the "supplier mark" system that prevents individuals or companies with a history of consumer abuse from obtaining new licenses. The consumer-focused tools have also been developed to increase transparency and confidence in the market. ERO has also expanded its supervisory toolkit beyond traditional complaint handling. The regulator now conducts regular audits of billing practices, contract terms, and sales procedures – often uncovering violations before consumers file complaints.
