The average price of electricity for this Saturday, May 23, 2026 is 36.52 euros per megawatt hour (MWh) in the wholesale market, according to data published by the Iberian Energy Market Operator (OMIE). The weekend begins like this with a new drop, this time 34.94% compared to Fridayleaving the ‘pool’ around 19.62 euros cheaper.
To avoid confusion, it must be remembered that this amount refers to the wholesale market, which does not include concepts such as taxes or tolls. These are only included in the Voluntary Price for Small Consumers (PVPC), which is the one that affects consumers with a regulated or indexed rate in the free market and is published late in the afternoon by Red Eléctrica.

REE plans to invest 607 million in network technology to save 400 million annually on the electricity bill
The Ministry for the Ecological Transition has started the hearing process for a new modification of the Development Plan for the Electric Energy Transmission Network 2021-2026, which contemplates an investment of 607 million euros. This proposal, promoted by Red Eléctrica de España (REE), aims to optimize the national infrastructure to mitigate the high cost of technical restrictions, which in 2025 amounted to a record figure of 3,351 million euros.
Through this reinforcement, the system seeks to drastically reduce dependence on combined cycle plants, which would reduce costs associated with the operation of the electrical system, in addition to reducing imports of fossil fuels and greenhouse gas emissions.
The technical strategy, as reported by Europa Press, focuses on the incorporation of state-of-the-art assets fully integrated into the network. Highlights include the installation of four electronic synchronous compensators (e-Statcom), designed to stabilize the inter-area oscillations of the European system, and the implementation of 28 new reactors intended for more efficient voltage control.
According to the calculations of the system operator, these joint actions will generate structural savings of more than 400 million euros annually, which would allow the investment to be amortized in less than two fiscal years while guaranteeing greater resilience in the management of energy flows between the south and north of the peninsula.
This third modification of the current plan raises the total investment commitment in the transmission network to 8,810 million euros with a horizon of 2026. The submission period, which will remain open until June 11, marks a key administrative milestone to consolidate an electrical network capable of absorbing the growth of renewable energies without resorting to inefficient adjustment mechanisms.
