He light price Break with the tonic of the last two days and shoot 47.81% compared to Friday, May 2. Thus, the price of the electric wholesale market, the so -called poolwill reach 16.17 euros the megavatio hour (MWh), in a context marked by volatility after the blackout that affected Spain Last Monday. This is reflected by the provisional data of the Iberian energy market operator (OMIE) collected by OKDIARIO.
The cost of pool electric played -4 euros/MWh on Friday after historical minimum of -10 euros/MWh on Thursday. However, this Monday, it is triggered again, although at levels not excessively high, since it comes from reduced prices.
In addition, for eight hours a day, electricity will have a zero cost or even negative. This interval will cover from 11:00 a.m. to 7:00 p.m., at which time the price will be returned at 2.2 euros/MWh.
The minimum of this Saturday will be -3 euros/MWh, a figure that will be repeated between 4:00 p.m. and 6:00 p.m., so the price of light continues to mark negative levels at some times of the day.
Light price today, Saturday
He Maximum price This Saturday will be registered between 10:00 p.m. and 11:00 p.m., when 63.8 euros/MWh will be reached. The fact that these days the price has negative levels at some times is related to the lowest demand and a greater participation of the renewable energies in the electricity generation, which are recovering after what happened.
However, it is important to emphasize that these wholesale market prices are not directly reflected in the consumer receipt welcomed to the regulated rate.
That is, it is not what appears on the electricity bill that reaches the end of the month to users who consume this energy from their homes. This is because the final amount also includes other fixed costs, such as tolls, positions and adjustments of the electrical system.
In addition, the price of the wholesale market, that is, the pooldoes not completely reflect the final cost of electricity for consumers received Regulated rate (PVPC).
This is due to the implementation of a new calculation method since 2024, which combines short -term prices With medium and long -term references to mitigate sudden fluctuations, without losing sight of the promotion of efficient savings and consumption.
In this scheme, the link with the price of pool It is gradually reducing. In 2024, futures markets represented 25% of the PVPC calculation, a proportion that has increased to 40% in 2025 and will reach 55% in 2026.
Influence of renewable energy
The report Installation of renewable energy in the peninsular electrical systempromoted by Ecologists in Action, uses simulations of the electrical system elaborated from real time data provided by Red Electric (REE) to calculate the capacity of the electrical system to integrate the energy produced by renewables.
According to the study, an excessive increase in installed power generates significant losses of potential energy in technologies such as windthe thermal and photovoltaic.
Rodrigo Iurzun, coordinator of the report, states that “the effect of installing too much photovoltaic energy is devastating because of the daily generation peak during the central hours of the day. If at one point the system is not able to absorb all energythe power must be limited to guarantee the stability of the network ».
Therefore, one of the hot topics after the blackout is the ability of the system to support the current distribution of its sources. The positive side is that the price the cheapest for consumers at some times of the day, even becomes negative.
