LUMA Energy warned on Wednesday, Oct. 28, that load shedding may hit Puerto Rico that night because the island did not have enough available power generation to meet demand.^[1] More than 150,000 customers lost service overnight, with more outages possible the next day.^[2] Periódico La Perla reported LUMA Energy counted 89,511 customers without electric service across Puerto Rico in a later reading.^[3] The warning of further cuts was echoed by several outlets the same day, tying the risk directly to insufficient generation capacity.^[4] Dr. José Caraballo Cueto said the LUMA Energy grid concession has not produced the drop in electricity costs that was expected of it.^[5] His comment lands as generation shortfalls, not distribution faults, drive this round of cuts - the part of the system LUMA Energy does not run. The figures moved through the day, from the overnight 150,000 to the 89,511 reading, which points to partial restoration rather than a single steady outage.^[6] Whether the grid holds through the night depends on how much generation comes back online.
