Grid Watch: About 4,390 Customers Out on a Typical Morning

Published Oct 12, 2026, 6:07 AM AST787daily · Original analysis

At a glance

  • 0.3% of customers out on a typical 6:00 AM this week (Oct 5–11)
  • Worst morning Oct 7: 0.33% out, led by Caguas
  • Previous week’s typical morning: 0.94%
  • Bayamón was among the ten towns with the most interruptions on 6 of 7 mornings

Why this matters: Whether outages are easing or getting worse for households: a week of mornings, against the week before.

On a typical morning this week about 4,390 of LUMA’s customers were without service at 6:00 AM — the middle reading of 7 mornings (Oct 5–11), out of about 1.47 million. A typical morning last week was 0.94% — this week is 0.64 points better.

The worst morning was Oct 7: 0.33% out (4,898 customers), led by the Caguas region. The quietest was Oct 6 at 0.05%.

Almost none of it was scheduled work — on average 0% of the customers out were on LUMA’s planned jobs, so these were faults rather than maintenance.
