Access capacity nodes

In compliance with RD 1183/2020 of 29 December, on access and connection to the electricity transmission and distribution networks in article 5 and CNMC Circular 1/2021, of 20 January, which establishes the methodology and conditions for access and connection to the transmission and distribution networks of electricity production facilities in article 12, we publish the access capacities at each of their voltage levels> 1 kV of the HV/HV and HV/MV substations operated by e-distribución Redes Digitales SLU.

These capacities are reported and calculated as defined in the Detailed Specifications for the determination of generation access capacity to the transmission grid and distribution networks approved in the resolution of 20 May 2021 from the CNMC.

All information relating to occupied, available and unresolved admitted access capacity is included.

The available access capacity for each node has been determined as the maximum additional active power that can be injected at that node, taking into account only the "occupied" capacity reported at all network nodes and the planned installation scenario without considering additional reinforcements, in accordance with the criteria of CNMC Circular 1/2021 and the Detailed Specifications for the determination of access capacity. This information, of an indicative nature, does not obviate the need to carry out a specific study for each individual request that takes into account any variation in the scenario, such as the consideration of the requests in the pipeline with the best order of priority, both in the node under study and in other nodes of the network that may have an influence on it.

The limitations that may exist in other distributors' grids, in the transmission grid or in the substation itself, due to aspects of its configuration or operation and those relating to the viability of connection, are not taken into consideration. Said limitations would be evidenced, as the case may be, in the corresponding acceptability and access and connection feasibility reports that must be carried out for each individual request.

The reported Available Access Capacity values should not be interpreted as simultaneous or summable capacity values. The connection of a generator at a node not only decreases the available access capacity at that node but also at the nodes of its neighboring network.

The reported values of occupied and admitted and unsettled capacity refer exclusively to generators connected or with access and connection permits granted or requested exclusively at these nodes, but not on lines or nodes of the underlying distribution network of these nodes.

Due to the fact that the publications are usually made on a monthly basis, it is possible that they reflect available capacity in a node that may already be exhausted by “Admitted and Unresolved” requests, both in the node itself and in others in the network with influence on it or in their underlying networks.

Except in exceptional and duly justified cases, requests for access and connection that do not comply with the range of maximum and minimum power per voltage level established in the Detailed Specifications will be refused. 

Requests made on nodes where the published capacity is 0 MW will be rejected, according to art 8.1 section d) of RD1183/2020.

Capacity map

In this map, you will find the e-distribución network nodes with the access capacity available for generation in each one of them indicated with a geographical approximation.

The capacity map should be considered a purely informative replica of the capacities published in the list of capacities in PDF. In case of discrepancies, the official values are those shown in the PDF.

The network capabilities map is currently unavailable. We are working to restore the service as soon as possible. Sorry for the inconvenience
