Electricity and Gas Prices Drop in Spain at the End of 2025
Electricity prices in Spain saw a significant drop in December 2025, falling by 30% compared to the same period last year. The average price stands at around €78.56 per megawatt-hour (MWh). Concurrently, butane has experienced its third consecutive price drop of the year, settling at €15.46 for the standard 12.5 kg cylinder. These reductions offer relief to consumers amidst inflationary pressures in other sectors like food and housing.
Drop in Electricity Prices
The average electricity price in December 2025 was €78.56/MWh, 30% lower than the €113.24/MWh from the previous year. This decrease occurs despite higher winter demand due to low temperatures and intensive heating use. The data comes from the wholesale market managed by OMIE, where the price remains above pre-pandemic levels but shows a clear downward trend.
Price Drop for Regulated Butane
The 12.5 kg butane cylinder has remained at €15.46 since mid-November 2025, following a 4-5% reduction. This is the third consecutive drop of the year, regulated by the Government and effective until the next bimonthly review in January 2026. This adjustment particularly benefits households not connected to the natural gas grid.
Forecast for 2026
The outlook for the first quarter of 2026 is optimistic. Under favorable conditions such as mild temperatures, stable liquefied natural gas (LNG) flows, and subdued demand in Asia, European gas could remain at €24-25/MWh. This would allow electricity prices in Spain to stabilize between €50 and €55/MWh, approaching pre-pandemic levels. However, volatility persists, as weather remains the primary factor in energy market fluctuations.
Context of Other Fuels
Gasoline prices have fallen for five consecutive weeks, while diesel shows a slight increase compared to the previous year. Brent crude has dropped by 22% in 2025, hovering around $59.60 per barrel, due to oversupply and geopolitical factors. These movements contribute to the general relief in energy costs for Spanish consumers.
