In early July, electric utilities in Ecuador and Venezuela announced scheduled maintenance that would cause temporary service interruptions. By the end of the month, unplanned outages struck communities in Maracaibo, Venezuela, after a transformer explosion left ten households without power, and in Montería, Colombia, where an overload damaged a medium‑voltage protection device. Local utilities and authorities responded by replacing equipment and urging residents to conserve electricity amid heat‑wave conditions, underscoring ongoing reliability challenges for power providers across the region.
