The CNMC has published Circular 1/2021 on January 20 to establish the methodology and conditions for grid access and connection to the transmission and distribution network. With this Circular, the process of reviewing the regulatory framework for access and connection is completed, which was initiated with Royal Decree 1183/2020.

The Circula defines the content for the grid access and connection request, the subsequent analysis and issuance of permits by the grid operator. In addition, values, percentages and ratios used are set out in the Annexes.

Finally, the Circular indicates that the grid operators will have a term that will not be less than 3 months (from the publication of RD 1183/2020) to publish the grid capacity based on the new criteria. Until this publication of the capabilities, no application for grid access is allowed.
