Hosting capacity assessment

Capacity type considered for available hosting capacity information (e.g., Firm and/or Flexible)

Firm

Description of what firm capacity means

Network capacity ignoring consumption and considering both connect and committed production

Description of the aspects/methodology that leads to firm capacity results

Nominal capacity of infrastructures and respect to NP50160 (Portuguese version of EN50160)

Description of what flexible capacity means (if applicable)

Capacity of the grid considering effects of consumption and variable capacity of lines

Description of the aspects/methodology leading to flexible capacity results

Based on synthetic load diagrams daily/seasonal and variable capacity of lines, flexible capacity is accessed

Description for the criteria and methodologies used that lead to the published information

Network capacity ignoring consumption and considering both connect and committed production, with respect to NP50160 (Portuguese version of EN50160). HV closed-loop grid capacity is limited to the instantaneous tripping current of the worst-case scenario.

Main assumptions/disclaimers behind calculations

1) The information provided by E-REDES constitutes an approximation of the values relating to substations and the MV network, as they are taken from the systems and have as a reference the moment at which the information is collected.

2) Given that the connection points, the electricity distribution network, and the consumption and generation values themselves are naturally very dynamic, the information made available may be subject to subsequent changes and updates, except for any omissions and/or occasional inaccuracies about the location that the information may contain. 

3) The information provided by E-REDES is only an approximation of the available network capacity at any given time, and therefore does not constitute a contractual proposal, nor does it dispense with the consultation of E-REDES for the purposes of formulating the usual requests for network connection. 

4) E-REDES safeguards that the information provided is non-binding and does not commit to a connection at any specific point or asset on the network, nor to any specific solution within the scope of potential network connection requests. E-REDES reserves the right to assess, on a case-by-case basis and in light of the respective requests, which technical solution is the most appropriate, in accordance with the principles to which it is legally bound. 

5) E-REDES is not held accountable to third parties, namely partners, service providers, contractors, users, and customers, for damages that may arise as a result, directly or indirectly, of the use of this information, in particular when carrying out interventions, calculations and/or estimates, without confirming the accuracy and currency of the data. Therefore, it is duly noted that consulting this information does not prejudice the obligation to engage in direct consultation with E-REDES to obtain updated information. 

6) The information available is, to all legal effects, the property of E-REDES, and must not be copied, reproduced, adapted, modified, changed, deleted, destroyed, broadcast, transmitted, disclosed, or in any way made available to a third party, without being expressly validated by E-REDES. The reproduction, commercialisation, or transfer to third parties, even if free of charge, outside the indicated assumptions or without express authorisation from E-REDES is prohibited under the applicable legal terms and may result in civil and criminal liability.

Additional information for connection request and hosting capacity information

Connection request procedure Large power plants with a connection exceeding 1 MW can access capacity through a competitive procedure or under a general regime, provided there is capacity available and a financial payment is made for the grid connection. Capacity can also be accessed by agreement. If there is no available capacity, producers are allowed to fund their own grid investments to create capacity. Power plants with less than 1 MW of connected power follow a simplified procedure and can connect only where no overloads are predicted.

Available options for the investors if the map shows “no capacity available” in their interested area Capacity can also be accessed by agreement. If there is no available capacity, producers are allowed to fund their own grid investments to create capacity.
Connection request rules/principles
  • Under the general regime – first come, first served
  • In the competitive procedure – auction
Information published for volumes of connection requests/waiting lines No
