On a typical morning this week about 13,795 of LUMA’s customers were without service at 6:00 AM — the middle reading of 5 mornings (Sep 28 – Oct 4), out of about 1.47 million. A typical morning last week was 0.06% — this week is 0.88 points worse. This week rests on 5 of 7 mornings: LUMA’s count could not be read on Oct 2 and Oct 3.
The typical morning this week left 13,795 customers without service, about 0.9% of LUMA’s roughly 1.47 million. Last week’s typical morning stood at 0.06%, so the middle of this week sat 0.88 points higher. The trouble was uneven rather than steady: Sep 28 was nearly clear at 0.04%, while Sep 30 was the worst morning, with 26,890 customers out, 1.83% of the total and led by the San Juan region. Oct 1 was also heavy, with 17,152 customers out, before Oct 4 settled to 1,847.
The towns that appeared among the ten with the most interruptions each did so on a single morning, so no one municipality carried the week. San Germán showed up to three interruptions at once, Hatillo up to two, and Aguadilla, Bayamón, Caguas and Cidra one each. Planned work was a small piece of the picture: on average 10% of customers out were affected by scheduled work rather than unplanned faults. One caution for planning: LUMA’s count could not be read on Oct 2 and Oct 3, so this week rests on five of seven mornings and may miss trouble on those two days.
