These changes focus on implementing a fifteen-minute deviation settlement period (ISP15), a measure aimed at aligning the electricity settlement system with European regulatory requirements.

The resolution aims to improve efficiency and accuracy in managing deviations between electricity production and consumption, in accordance with European electricity balancing regulations.

As explained in the document, ISP15 will allow for more frequent and detailed adjustments, ensuring greater accuracy in compensations and promoting a more balanced and flexible electrical system.

Although the resolution anticipates a time gap between the entry into force of ISP15, scheduled for December 2024, and the implementation of the settlement period in intraday energy markets (MTU15), the CNMC has established transitional measures to mitigate potential impacts on market participants during this period.

“Switching to a settlement every fifteen minutes instead of hourly will allow for better asset management, benefiting those who have invested more in controlling their operations,” explains Carlos Martín Graña, Operations Manager at ENERJOIN.

In an interview with Energía Estratégica España, the consultant highlights that this transition will require companies to make a significant effort to adapt their systems, particularly those that have not prioritized detailed monitoring of their assets.

He also warns that market participants who do not adapt in time could face economic disadvantages compared to more prepared competitors.

This is a wake-up call for professionals and companies in the information technology (IT) sector to develop systems that can make these processes more efficient.

For his part, Luis Marquina, President of AEPIBAL, believes this measure adds a high level of granularity to battery management, which makes management more complex but will improve performance.

“The more offers can be fine-tuned, the better prices will be achieved,” emphasizes the executive, highlighting the opportunity to achieve even cheaper prices that are more aligned with operations.
