The wholesale electricity market sets an average price for this Friday, September 18, of 124.78 euros per megawatt hour (MWh), which is 2.07% lower than yesterday, according to data published by the Iberian Electricity Market Operator (OMIE). The day follows the pattern of recent days, with a very cheap central period and high peaks early in the morning and late in the afternoon.
The most expensive period will occur between 08:00 and 09:00, when the price will reach 209.43 euros/MWh. The previous hour will also exceed 200 euros, with 208.50 euros/MWh between 07:00 and 08:00. The information, gathered by larazon.es, details that the price will drop rapidly from 09:00, falling below 4 euros by 11:00.
The cheapest period of the day extends from 14:00 to 16:00, with 0.00 euros/MWh in both slots. This window of minimum prices allows for concentrating the use of high-consumption appliances, such as the washing machine or dishwasher, without incurring a significant energy cost on the bill.
After 17:00, the price will rise quickly again: it will go from 41.20 euros/MWh to 127.16 euros/MWh an hour later, reaching 191.01 euros/MWh between 19:00 and 20:00 and hitting 202.96 euros/MWh between 20:00 and 21:00. The last hour of the day closes at 159.10 euros/MWh.
These amounts correspond to the wholesale market and do not reflect the final price paid by the consumer, as fees, charges, and taxes are added to the bill. For households with a tariff indexed to the daily market, the expenditure depends on actual consumption during each time slot.
The early morning starts with high prices: 187.19 euros/MWh between 00:00 and 01:00, dropping to 171.59 euros/MWh between 04:00 and 05:00 before rising again.
