Spain’s wholesale electricity price fell to 106.90 €/MWh on October 8, 2026, down 41.37% from the day before. For several midday hours, the market price will hit zero, an unusual drop in a country where prices often swing sharply.
From noon to 4 p.m., the Iberian electricity market will offer power at 0.00 €/MWh, information from the Operador del Mercado Ibérico de Energía (OMIE). The cheapest slot is 12:00 to 13:00. By evening, the picture flips: the 8 p.m. to 9 p.m. hour will cost 198.80 €/MWh. For anyone on a variable tariff, the timing of chores or charging an electric car could mean paying nothing or nearly double the daily average.
Why the wild swings? Autumn and spring usually bring lower demand in Spain. Milder weather means less need for heating or air conditioning, giving the grid a break. But the market remains on edge: ongoing conflicts in the Middle East could push gas prices higher, quickly driving up electricity costs again. Sector publications referencing OMIE and Red Eléctrica point out that the wholesale “pool” price is just one part of the regulated PVPC tariff. The final bill also includes network tariffs and taxes, along with other regulated charges.
Spain’s electricity prices move in step with the rest of Europe. On October 8, Spain and Portugal are among the cheapest countries for power; only Finland and Sweden have lower spot prices. Meanwhile, rates top 200 €/MWh in Hungary and Romania, with Italy also facing higher prices. These cross-border links mean that a surge in renewables or a spike in demand elsewhere can quickly show up on Spanish bills.
The spot price is only part of what households pay. Regulated tariffs like PVPC add fees, including capacity payments and other extra charges. Sector publications referencing OMIE and Red Eléctrica report that nearly eight million Spanish households on the regulated PVPC tariff are more directly affected by wholesale market changes; customers on free-market contracts pay information from their supplier agreements. Even when the OMIE price is zero, regulated payments remain, while network costs, taxes and commercial margins still apply. “Free electricity” covers only the market energy component. The final price for consumers is set after Red Eléctrica de España publishes the day’s rates, usually after 8:15 p.m. the night before. Until then, the spot price is just a guide. Since 2024, the PVPC formula has started to include long-term futures prices to smooth out big swings. By 2026, 55% of the reference will come from futures. So even when the spot price drops to zero, PVPC customers won’t get free electricity across the board.
Recent trends show how jumpy the market has been. In the week before October 8, spot prices ranged from 152.01 €/MWh to 201.99 €/MWh. The average wholesale electricity price in Spain reached 201.99 €/MWh on October 6, the highest level since December 2022, according to reports based on OMIE data. Weekends usually bring the lowest rates, so shifting high-use activities to weekends or the zero-cost midday hours can save money for those who pay attention. Reports cite a jump in gas prices and higher demand as the basic reasons for recent price spikes; the Spanish MIBGAS benchmark hit 75.25 €/MWh on October 6.
For people tired of chasing daily price changes, fixed-rate contracts are an option, though they don’t always guarantee the lowest price. Adjusting contracted power to match real household needs can also help avoid overpaying. Free online calculators can help consumers fine-tune their settings.
This brief window of zero-cost power shows how much timing matters in Spain’s energy market. Midday savings are rare, and volatility means households need to adjust their usage as prices shift to keep bills in check. The current drop shows how quickly prices can change, and how easily consumers can miss the cheaper hours.
