Slovenian Energy Market 2025: Household and Industrial Electricity Prices Record Annual Declines

The Slovenian Ministry of the Environment, Climate and Energy has released its final statistical report for 2025, revealing a general cooling of retail electricity prices across the country. According to the data, which covers the fourth quarter and the full calendar year, households and non-household consumers both benefited from lower year-on-year costs, driven largely by significant adjustments in grid fees and government exemptions.

Household Sector: Grid Fee Relief Offsets Rising Energy Costs

For the average Slovenian household, the retail electricity price in 2025 settled at €95 per MWh, representing a 4% decrease compared to 2024. This downward trend continued into the final months of the year, with Q4 prices dipping an additional 2%.

While the overall retail price fell, the underlying “electricity component”—the cost of the energy itself—actually rose by 7% to an average of €111 per MWh (excluding VAT). The net reduction for consumers was primarily achieved through aggressive cuts to regulated charges:

  • Grid Fees: Averaged €42.1 per MWh (excluding VAT), a substantial 30% reduction from the previous year.

  • Policy Support: Households enjoyed a total exemption from renewable energy (RES) and high-efficiency cogeneration (CHP) fees during the first half of 2025, with partial exemptions remaining in place for the second half. These surcharges averaged just €5.2 per MWh.

  • Excise Duty: Stood at €1.53 per MWh.

By the end of 2025, the cost structure for a typical household invoice consisted of the energy component (56.9%), grid fees (21.6%), VAT (18%), energy taxes (2.7%), and excise duties (0.8%).

Non-Household Sector: Significant Annual Savings Despite Q4 Spike

The broader consumer category, dominated by the business and industrial sectors, saw an even sharper annual decline. The average price for non-household consumers in 2025 was €181 per MWh, a 13% drop over 2024.

However, the sector faced a volatile end to the year; while annual figures were down, prices in the fourth quarter alone actually climbed by 6%.

The ministry highlighted a across-the-board reduction in core cost drivers for businesses:

  • Energy Component: Decreased by 13% to €116.7 per MWh.

  • Regulated Grid Fees: Also fell by 13%, averaging €20.7 per MWh.

  • Fiscal Charges: Energy taxes dropped 14% to €9.5 per MWh, though excise duties saw a marginal increase of 2% to €1.3 per MWh.

For these consumers, the energy component represents the vast majority of the total cost at 78.7%, followed by grid fees at 14%, energy taxes at 6.4%, and excise duties at 0.9% (all figures excluding VAT).
