Power Outages

This ranking compares how reliable everyday electricity supply is. The raw value shows estimated power outage hours per year; fewer outage hours indicate a more stable grid and receive a higher rating.

How the Raw Value Is Calculated

The raw value is estimated electricity outage hours per year. It describes how many hours electricity users can expect supply interruptions in a country. Lower values are better.

There is no complete official global SAIDI or SAIFI series. Nomadino therefore uses a harmonised outage-hour value from public enterprise surveys, grid-loss data, national grid and regulator information, and maintained territory replacements.

The rating is calibrated to everyday usability: up to 10 hours per year receives 100 points, while 500 or more hours receives the lower scale point. Values in between are scaled linearly.

For small territories without their own public series, replacement values are derived from the administering state, island context, regional grid reliability, electrification rate and available infrastructure context.

This indicator measures electricity-supply reliability, not electricity price, renewable share or the climate impact of the power mix.
