Electricity prices today, May 18 by hours: when it is cheaper and when it is more expensive

CE Noticias Financieras  


    The price of electricity continues to soar in Spain. The main cause is the increase in gas prices due to the war in Ukraine. This raw material is used to generate electricity in combined cycle power plants, and as this energy source has been used to cover part of today's electricity demand, the price per megawatt hour is skyrocketing.

    Specifically, and according to data from OMIE, the regulator in Spain and Portugal, for this Wednesday, May 18, the price of electricity will be 194.86 euros/MWh, a price 150% higher than a year ago, when the price was 77.65 euros/MWh.

    This price, however, will only apply to households that have contracted a regulated tariff (PVPC), almost 11 million in Spain. As long as they have their bill in the free electricity market, they will only notice the increase when their contract is updated on an annual basis.

    At what time is electricity cheapest?

    The cheapest time for electricity will be in the afternoon. Specifically, between 14.00 and 15.00 hours, when electricity will cost 165.04 euros/MWh.

    At what time is electricity most expensive?

    The most expensive time to turn on the electricity will be at dinner time, between 21.00 and 22.00 hours, when it will cost 237.72 euros/MWh.

    Why does the price of electricity vary so much?

    The main cause of the price fluctuations is that the price of gas is rising sharply and its use is essential for the production of energy in the so-called combined cycle power plants. Thus, any impact on the price of gas has an almost immediate impact on the price of electricity.

    The current context does not exactly help to contain gas prices. Russia is one of the largest gas suppliers on the planet and the influence of the war in Ukraine has been felt halfway around the world, including Spain.
