E-REDES: Cargas nas Subestações

Published by E-REDES, Distribuição de Eletricidade / PT / Yearly

Grantedcommercial_use_with_attributionHealthy

For each HV/MV substation of mainland Portugal's distribution network, winter and summer: the extra load it can supply with N-1 security (availability), the headroom that exists only while every transformer is in service, its guaranteed (N-1) power and its installed transformer power, in MVA, for the RARI year.

What is withheld, and why

Nothing is withheld. Values are served with the attribution the licence asks for: E-REDES (Distribuição de Eletricidade), "E-REDES Open Data Portal", https://e-redes.opendatasoft.com/pages/homepage/. Keep it with any figure you show.

Switched to commercial_use_with_attribution on 2026-10-02 on the owner's report that the operator gave permission by telephone. No written confirmation is on file: ask for one, and an objection from the operator means rights_override = blocked the same day. The evidence below is the operator's published terms as read before the call. Before: Same conflict as pt_eredes_capacidade_rececao: CC BY 4.0 in the licence field and English description, and a clause 6 in the Portuguese description forbidding reproduction, commercialisation or transfer to third parties without E-REDES' express authorisation. The stricter reading wins until E-REDES confirms in writing (target commercial_use_with_attribution; fallback link_only). Re-read live on 2026-09-26.

E-REDES substation load headroom with N-1 security

pt_eredes_carga_n1 · vRARI 2025 (data_processed 2026-04-22)

The power a HV/MV substation can supply after the loss of its largest transformer, MV back-feed included (guaranteed power), and the part of it above the substation's natural load (availability), per season. MVA.

The operator’s own caveats

  • The information provided by E-REDES consists only of an approximation of the available capacity of the networks at any given time, and therefore does not constitute a contractual proposal.

E-REDES substation load headroom without N-1 security

pt_eredes_carga_nao_garantida · vRARI 2025 (data_processed 2026-04-22)

Installed power that is not guaranteed and exceeds the substation's natural load: extra load that can be supplied only while every transformer is in service, per season. MVA.

["794 rows = 397 substations × two seasons; season (inverno_verao: Inverno → winter, Verão → summer) is a series dimension, never averaged or merged.","disponibilidade (\"guaranteed power exceeding natural load\": extra load suppliable with N-1 security, MV back-feed included) → available, firm. It is the operator's firm offtake headroom.","potencia_instalada_nao_garantida (non-guaranteed installed power exceeding natural load) → available, conditional: headroom that holds only while every transformer is in service, on top of the firm availability. Not flexible, which here means a stated curtailment band, and none is stated.","potencia_garantida (the N-1 firm rating before any load) → total, firm; potencia_instalada (sum of transformer primary ratings) → installed. Natural load, non-guaranteed power and non-guaranteed load are inputs and stay in raw_record.","Values are kept as published: availability is 0 in 137 rows, and potencia_garantida is negative in two winter rows (−0.7 Vila Nova de Cerveira, −0.2 Casal de Cinza), flagged negative_value.","ano is the reference year; the operator does not say which day of it, so records carry no effective date of their own and the run's is the dataset's data_processed.","Keyed by codigo_da_instalacao, which joins exactly to the capacity dataset's codigo (the shared eredes_instalacao identifier). Location as in pt_eredes_capacidade_rececao: municipality from the code's INE prefix, no coordinates.","Non-additive across substations: the MV back-feed that makes the N-1 figures is shared between neighbours."]
