Spain is one of the countries with the most expensive electricity system in the world. That is why the wholesale electricity markets, called pool, hold auctions every day to find out what the price per Megawatt per hour (MWh) will be.

According to data from the Iberian Energy Market Operator (OMIE), the price of electricity is down 11% compared to Wednesday, May 24, when it cost 85.23 euros/MWh. Today it costs 75.88 euros.

It was thus made known that the cheapest hour of light will be between 15 to 16 hours, at a price of 34.99 euros per megawatt hour. It is recommended to make the greatest use of electricity in this time slot.

On the other hand, the maximum electricity price will be from 22 to 23 hours, at a price of 106.29 euros/Mwh.

The price is established day by day and also depends on the different origins it has: gas-fired thermal power plants, hydroelectric power plants, nuclear power plants or renewable energies. Each energy origin generates a different MWh price.

This means that the days when gas or hydroelectric power plants provide energy are the days when the MWh costs the most.

Electricity is condensed into a pricing system. Wholesale markets and power generation vary the daily value of this service.

While this marginalist system provides several advantages such as prioritizing low-emission energies, encouraging investment in renewable technologies and more.

However, it also has major disadvantages such as sensitivity to demand to raise the price. As well as days where the light has a very high price because of fluctuations in energy systems.
