What these network averages measure

Duration and frequency use delivery points

SAIDI is the sum of long-interruption durations across delivery points divided by the number of delivery points. Here it is measured in minutes per delivery point. SAIFI is the corresponding number of long interruptions per delivery point. MT means medium voltage; BT means low voltage.

A municipality is a reporting geography, not a feeder boundary. The data can include interruptions originating upstream or in private installations, so these values do not assign fault to the distribution operator.

Event exclusions change the question

The dataset dashboard’s Analysis Criteria explicitly exclude interruptions resulting from exceptional events. The 2025 operator report confirms that its continuity results include planned and accidental interruptions and exclude approved exceptional events.

ERSE’s regulatory comparison uses accidental long interruptions only. These combined API rates must not be used to infer a compliance breach. They do not measure renewable curtailment, hosting capacity or required household battery backup.

E-REDES 2025 report, pages 14 and 18 · ERSE 2025 report, page 94

A bounded edition, with dates kept separate.

Observation period: 1 January to 31 December 2025. One annual record per municipality, with four medium- and low-voltage measures.
Capture and source processing: Snapshot captured 23 October 2026 UTC. The publisher’s data processing timestamp is 8 October 2026; its metadata processing timestamp is 21 October 2026. These processing dates are not publication or revision dates.
Publication and revision dates: Not supplied for this API edition. E-REDES describes the data as approximate system extracts that can change. A later snapshot must retain this edition and identify revised values.
Refresh: The publisher describes annual updates. This site serves one frozen edition, with no automatic collector.
Why quality-zone rows are excluded: The source does not explain whether a zero in a quality-zone row means no interruptions or no delivery points. This edition includes municipal totals only. All four selected values are populated and strictly positive for each of the 278 rows. A future zero or missing value requires review.

Risk and accountability in the evidence puzzle · Data operations. This is evidence for one operator’s distribution footprint, with municipal detail; it does not complete a worldwide network comparison.

Excluded by publisher

Long interruptions last more than three minutes. Planned and accidental interruptions are combined. This record excludes exceptional events and therefore does not describe every outage experienced.

What these network averages measure

Duration and frequency use delivery points

Event exclusions change the question

A bounded edition, with dates kept separate.

Observation period

1 January to 31 December 2025. One annual record per municipality, with four medium- and low-voltage measures.

Capture and source processing

Snapshot captured 23 October 2026 UTC. The publisher’s data processing timestamp is 8 October 2026; its metadata processing timestamp is 21 October 2026. These processing dates are not publication or revision dates.

Publication and revision dates

Not supplied for this API edition. E-REDES describes the data as approximate system extracts that can change. A later snapshot must retain this edition and identify revised values.

Refresh

The publisher describes annual updates. This site serves one frozen edition, with no automatic collector.

Why quality-zone rows are excluded

The source does not explain whether a zero in a quality-zone row means no interruptions or no delivery points. This edition includes municipal totals only. All four selected values are populated and strictly positive for each of the 278 rows. A future zero or missing value requires review.
