HERA determined new guaranteed electricity supply tariffs for HEP Elektra in December

The Croatian Energy Regulatory Agency (HERA) has determined the tariff rates for the guaranteed supply of electricity for the energy entity HEP ELEKTRA d.o.o., Ulica grada Vukovara 37, Zagreb, for December 2026. The decision was published in Narodne novine no. 130 of November 11, 2026, under number 1535, and enters into force on December 1, 2026. This changes the billing for all customers who purchase electricity within the framework of the guaranteed supply.

The decision was made by the Agency’s Management Board at its 23rd session held on November 9, 2026, and was signed by the President of the Management Board assoc. prof. dr. sc. Nikola Vištica. The legal basis is Article 11, paragraph 1, point 10 of the Energy Activities Regulation Act, Article 29 of the Energy Act, and Article 112, paragraph 1, subparagraph 1, point 9 of the Electricity Market Act, and the rates were calculated according to the Methodology for determining the amount of tariff rates for the guaranteed supply of electricity (Narodne novine no. 101/26).

The decision bears the classification 391-35/25-01/1 and registry number 371-06-26-28. The tariffs are, as before, structured in two steps: specifically for the first two months of using the guaranteed supply and specifically for the period thereafter, according to high and low voltage tariff models.

Tariff rates for the first two months of use

For active energy, in euros per kilowatt-hour, the decision for December 2026 determines:

• High voltage: ENVT 0.343706 and ENNT 0.343706
• Medium voltage: ENVT 0.356435 and ENNT 0.356435
• Red model: ENVT 0.351343 and ENNT 0.351343
• Low voltage, White: ENVT 0.262961 and ENNT 0.176961
• Low voltage, Blue: ENJT 0.219961
• Low voltage, Yellow: ENJT 0.348797

The supply charge is the same in all models and amounts to 4.65 euros per month.

Tariff rates after two months of use

For the period after the first two months of guaranteed supply, the decision determines higher amounts:

• High voltage: ENVT 0.381514 and ENNT 0.381514
• Medium voltage: ENVT 0.395643 and ENNT 0.395643
• Red model: ENVT 0.389991 and ENNT 0.389991
• Low voltage, White: ENVT 0.291887 and ENNT 0.196427
• Low voltage, Blue: ENJT 0.244157
• Low voltage, Yellow: ENJT 0.387165

Higher rates than in November

A comparison with the decision for November 2026, published in Narodne novine no. 117, shows that certain rates are significantly higher. For example, for high voltage in the first two months, the ENVT rate rises from 0.277200 to 0.343706 euros per kilowatt-hour, which is an increase of about 24 percent, while for the White model at low voltage, the increase is from 0.251961 to 0.262961 euros, about 4 percent.

Growth is also present in the second step of billing: high voltage moves from 0.307692 to 0.381514 euros per kilowatt-hour, and the Yellow model from 0.309971 to 0.387165 euros per kilowatt-hour. The supply charge remained unchanged at 4.65 euros per month.

What this means for bills

The decision directly affects the accounts of customers who have not chosen a supplier on the market and receive electricity through guaranteed supply, which in such cases is provided by HEP ELEKTRA d.o.o. Since it applies from December 1, 2026, the new items will be visible on the December bills, and the difference compared to November will depend on the tariff model and the consumption of the household or entrepreneur.
