Consumers will have to be vigilant this Sunday, November 19. There will be times when running the washing machine, ironing or using the oven will be more advisable. Knowing which are the cheapest allows you to concentrate your spending and save on your bill at the end of the month. The average reference for the entire day in the wholesale market will be 71.19 euros per megawatt hour (MWh), according to the operator OMIE. Again, hour by hour there will be big differences.
The wholesale market figures are reflected in the consumer’s receipt. The most expensive time will be reached between 8:00 p.m. and 9:00 p.m., when the price on the invoice will rise to 0.15404 euros per kilowatt hour (kWh), based on data from Red Eléctrica. The cheapest hour, on the opposite side, will be recorded between 11:00 and 12:00, when the kilowatt hour will be paid at 0.05204 euros.
Why does the price of electricity vary in each time slot?
The regulated bill prices are dynamic, indexed to the wholesale electricity market. As the energy demand per hour is the factor that determines the price of electricity in each time slot, the cost of electricity per hour varies constantly. Thus, with greater demand in peaks of cold – for heating – or heat – for air conditioners, for example -, prices rise. In addition, it must be taken into account that costs such as adjustment services, marketing, tolls and charges, capacity payments or interruptibility costs, among others, may vary every hour.
