A widespread, multi-hour power outage that swept across all communities in Antigua on the evening of July 27 is now the focus of a formal internal review by the Antigua Public Utilities Authority (APUA) Electricity Business Unit, as officials work to identify gaps in grid resilience and plan corrective action to prevent similar disruptions going forward. The system-wide outage began late Monday night, leaving residents and businesses without electricity for hours, with full service restoration achieved in the early hours of Tuesday.
Andre Matthias, the top manager of APUA’s Electricity Business Unit, gathered with his technical team this week to walk through the full timeline of the blackout, assess the root cause of the fault, and evaluate the utility’s on-the-ground response to the incident. Investigators have already pinpointed a failed lightning arrester as the source of the failure that triggered the widespread outage.
The impact of the extended blackout rippled across daily life in Antigua: critical public infrastructure including streetlights went dark, residential cooling systems were knocked offline amid warm temperatures, and commercial operations were disrupted, with multiple local businesses forced to close their doors early as the outage stretched past midnight.
APUA officials confirmed that restoration crews worked through the night to bring power back online, using a targeted approach that isolated the damaged section of the transmission grid to allow gradual re-energizing of unaffected parts of the network. By 3:53 a.m. on Tuesday, all feeders had been repaired and power was restored to every affected community. Moving forward, the authority has scheduled full structural repairs on the isolated, damaged section of the transmission line, alongside a broader set of mitigation measures designed to lower the probability of future system-wide outages.
