The CNMC has approved Circular 1/2024, providing clear principles for access to electricity networks, promoting system security, service quality, and maximizing network utilization. The regulation allows demand facilities to opt for flexible access, enhancing electrification even in areas with limited capacity.

The circular defines access and connection criteria uniformly across the territory, ensuring a transparent and efficient process for applicants. It emphasizes transparency and non-discrimination, detailing minimum content requirements for web platforms managing access requests.

The regulation anticipates new consumption models in a digitalized environment, introducing mechanisms like flexible access for new entities such as batteries or electrolyzers. Specific criteria for evaluating access to storage facilities are also established, along with flexible access permissions.
