On a typical morning this week about 841 of LUMA’s customers were without service at 6:00 AM — the middle reading of 7 mornings (Sep 21–Sep 27), out of about 1.47 million. One morning carried the week: Sep 24, when 7,944 customers were out — about nine times a typical morning, led by the Bayamón region.
Most mornings this week, LUMA’s 6:00 AM readings showed a quiet grid: the middle reading came to about 841 customers without service, out of roughly 1.47 million on the books. That calm was broken by a single morning, Sep 24, when 7,944 customers were out — about nine times a typical morning — with the Bayamón region leading the trouble. Outside that one spike, the rest of the week settled back down quickly, including the quietest morning, Sep 22, when only 497 customers were affected.
Measured as a share of all customers, a typical morning this week ran at 0.06%, and even the roughest morning topped out at 0.54%. A typical morning last week ran at 0.24%, so this week’s was 0.18 points better. For context, LUMA logged about 1% of the affected customers as planned outages rather than unplanned faults, meaning most of what showed up on the portal this week reflected unplanned trouble rather than scheduled maintenance.
