The CNMC has announced the continuation of pilot projects aimed at involving large electricity consumers and distributors in the dynamic control of electrical grid tension. This initiative is crucial for maintaining the safety thresholds of the electrical supply.

The resolution published by the CNMC extends the regulatory sandbox project, which allows large consumers, such as factories, to actively contribute to managing grid tension. Additionally, a new project is set to be designed by Red Eléctrica de España, with a deadline for completion by June 2026.

Maintaining grid tension within safety limits is essential for reliable electricity supply. Traditionally, electricity generation has managed this task, while consumers have been passive participants. The current project invites large energy consumers to voluntarily maintain an inductive power factor, consuming excess reactive energy that causes overvoltages, in exchange for variable compensation and exemptions from certain charges.

The project, which began in February 2024, has been extended to attract more participants and yield more robust results. This extension allows the system to continue leveraging the capabilities of large consumers while the development of the approved tension control service progresses.

In line with EU Directive 2019/944, which emphasizes the active role of demand in energy transition, the CNMC is promoting these pilot projects to advance towards a market-based service model that encourages active participation from all market agents.
