The average price of electricity for this Sunday, May 10, 2026 for consumers with a regulated or indexed rate in the free market, rises slightly to 83.73 euros per megawatt hour (euros/MWh), according to data published by Red Eléctrica. This means that electricity is paid 0.97 euros more than this Saturday, when the price stood at 82.76 euros, that is, it has become more expensive by 1.17%.
It should be remembered that these amounts refer to the PVPC (Voluntary Price for Small Consumers), an amount that varies from that published by the Iberian Energy Market Operator (OMIE) where the wholesale market data is reflected, which are usually lower because they do not include concepts such as taxes and tolls.

How the quarter-hour system influences the price of PVPC
Since September 30, 2025, the Spanish electricity market sets prices every 15 minutes instead of every hour. This model, known as the quarter-hour system, divides the day into 96 sections in which supply and demand are adjusted in the wholesale market managed by OMIE.
Although domestic meters continue to measure consumption by the hour, which requires the average of the four quarter-hour prices to be applied in each 60-minute section, this format makes it possible to more accurately reflect sudden variations in renewable generation. When solar production drops in the late afternoon or the wind increases punctually, the price readjusts in a matter of minutes.
The change fully affects consumers covered by the PVPC, since their bill depends on the wholesale market. For those who have solar self-consumption, the surpluses discharged into the grid are now also valued according to the quarter-hour period in which they are injected.
