Spain electricity price August 2026 OMIE peak price hourly rates

On 3 August 2026 the wholesale electricity price in Spain surged, reaching a peak of 213 €/MWh between 21:00 and 22:00, with the average price for the day at 146.37 €/MWh – a 3.62 % drop from the previous day’s 151.87 €/MWh but still well above the 180 €/MWh level that marked the start of the week. The cheapest hour was 14:00‑15:00 at 80.10 €/MWh, while the most expensive hour was 21:00‑22:00 at 213.18 €/MWh. The following day, 4 August, the price fell again, with the lowest rate of 76.47 €/MWh between 13:00‑14:00 and a daily average of 146.37 €/MWh, a 3.62 % decrease from the previous day. However, nine hourly slots still exceeded 180 €/MWh, and the night‑time periods remained the most costly, with prices above 190 €/MWh between 20:00‑22:00. The data, published by the Iberian Electricity Market Operator (OMIE), show a volatile market driven by high summer demand and a brief return of zero‑price slots that disappeared after the weekend.
