Natural gas prices in Slovenia moved in opposite directions for households and non-household consumers last year. Residential users benefited from lower retail prices, while businesses and other non-residential consumers faced a moderate increase in their average gas costs.
In 2025, the typical household paid around 86 euros/MWh, marking a 9 % decrease compared to 2024. The reduction was primarily driven by a drop in the supply component, which fell by about 11 % to 51.8 euros/MWh. Network charges also declined slightly, down 4 % to an average of 12.7 euros/MWh. Other elements of the household bill, including environmental and energy-related levies for renewable energy, high-efficiency cogeneration, and energy efficiency contributions, remained unchanged. The excise duty on natural gas also stayed at the same level.
For non-household consumers, the trend was notably different. Businesses paid slightly over 68 euros/MWh on average, an increase of roughly 5 % from the previous year. The gas supply cost remained the largest portion of their bill, accounting for just over 81 %, rising by about 2 % to 45.3 euros/MWh. Network charges also increased more sharply, climbing 16 % to 5.8 euros/MWh, representing just over 10 % of the final bill. Additional energy-related charges contributed further to the increase, averaging 4.2 euros/MWh or about 7.5 % of the total price, up 28 % from 2024. The excise duty rose slightly by 4 % to 0.4 euros/MWh, though it remained less than 1 % of the total cost for businesses.
