Firm demand access capacity at network nodes

Check the availability of power for demand facilities at our network nodes

What information will you find here?

On this page, you can check the available firm access capacity for new demand installations at the nodes of the e‑distribución grid with a voltage exceeding 1 kV and also for EASA and Ceuta.

We publish this information in accordance with current regulations on access and connection to the electricity grid.

What is firm demand access capacity?

Firm access capacity is the maximum additional capacity that can be demanded at a grid node without carrying out reinforcement work, according to established technical criteria.

This information is indicative.
Each specific application must be analysed through an individual study.

Important aspects to consider

  • The published capacities are neither cumulative nor simultaneous.
  • New demand at one node can reduce the available capacity at other nearby nodes.
  • Potential limitations in other grids, the transmission grid.
  • These limitations are analysed in the acceptability and feasibility reports for each application.

Updating information

The information is updated monthly, using data from the previous month.
A node may show available capacity that has been compromised to previous applications.

Application notices

  • Applications must adhere to the capacity ranges per voltage level.
  • Important notice: applications expressly indicating a node with a published capacity of 0 MW may be rejected.
  • Demand applications are not required to indicate the specific node where they wish to connect.
  • Applications may require an acceptability report from the System Operator.

NOTE FOR STORAGE REQUESTS

Storage requests cannot be processed, as they constitute flexible demand and are pending the relevant regulatory framework.

Capacity thresholds by voltage level

In the following table, you can consult the maximum and minimum capacities permitted for access and connection applications, according to voltage level.

The indicated values do not guarantee the existence of capacity, which will be confirmed in the specific study.

¹ The values indicated in the table do not imply the existence of access capacity, as this will be determined by a specific study, applying the criteria established in section 3.6 of these Detailed Specifications.
² Not applicable to these voltage levels.
