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

March 5, 2026 by AEA in News

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).
