Jamaica's all-island blackout leaves 65,000 still without water

Jamaica's national grid collapsed on Friday night, June 5, 2025, plunging virtually the entire island into darkness in what became one of the most disruptive blackouts in recent memory. The Jamaica Public Service Company began phased restoration overnight, and by Saturday morning more than 500,000 customer accounts had been re-energised — but the damage was already cascading well beyond the electricity sector.

As the lights went out, so did the pumps. The National Water Commission reported that treatment plants and distribution systems across multiple parishes lost power, triggering a water supply crisis that proved far slower to resolve than the electricity outage itself. By 2:00 p.m. on Saturday, June 6 — nearly 18 hours after the initial blackout — approximately 65,000 NWC customers, roughly 12 per cent of its entire customer base, were still without water supply. Full restoration was projected to take a further 24 to 48 hours.

Parish-level disruptions were widespread. In St. James, the Terminal Reservoir and Appleton tank required replenishment before distribution could resume. Manchester's Ingleside, Pusey Hill and Warrick Relift facilities faced particular challenges, affecting the Perth Estate systems. In St. Catherine, Old Harbour — a major distribution hub — suffered a second, unrelated electrical fault after initial power was restored, compounding delays. Similar secondary outages hit facilities in Clarendon, St. Elizabeth and St. James.

Energy Minister Daryl Vaz publicly branded the situation 'unacceptable' and called an emergency meeting with JPS leadership, demanding answers on how the all-island failure occurred.

• System-wide blackout struck Jamaica on Friday night, June 5, 2025 • More than 500,000 customer accounts re-energised by Saturday morning • Approximately 65,000 NWC customers — 12 per cent of its base — still without water at 2:00 p.m. Saturday • Full water restoration projected within 24 to 48 hours of Saturday afternoon • Affected parishes included St. James, Manchester, St. Catherine, Clarendon and St. Elizabeth • Secondary, unrelated electrical faults delayed restoration in Clarendon, St. Elizabeth and St. James • Old Harbour suffered a second outage after initial power restoration • Energy Minister Daryl Vaz called the blackout 'unacceptable' and demanded an emergency meeting with JPS

The June 5 blackout underscores a structural vulnerability common across Caribbean island states: energy and water infrastructure are deeply interdependent, meaning a single grid failure can rapidly become a public health emergency. 

With 65,000 water customers still unserved 18 hours after the initial outage, and secondary electrical faults compounding delays in Clarendon, St. Elizabeth and St. James, the event illustrates how cascading failures can outpace even well-intentioned restoration efforts.

"Approximately 65,000 customers — about 12% of the NWC's customer base — remained without water supply at 2:00 p.m. Saturday, June 6, nearly 18 hours after the initial blackout."

Government accountability and urgency: Minister Vaz took an unambiguous public stance, posting on X that the blackout was 'unacceptable' and committing to monitor the situation until full restoration. He said he had requested an emergency meeting with JPS leadership and indicated a press briefing would follow, signalling political intent to hold the utility to account.

Utility context — prior storm damage as background factor: JPS stated that its systems sustained significant storm-related damage during Hurricane Melissa in October, offering this as contextual background. However, a formal investigation has not yet determined whether, or how, that prior damage contributed to the June 5 grid failure, and JPS has not publicly assigned a specific cause.

Operational transparency and public health prioritisation: Minister Samuda used Saturday's press conference to provide granular parish-level updates and explain the technical lag between electricity and water restoration. He confirmed the NWC had prioritised hospitals and detention facilities and reactivated the joint NWC/JPS Task Force to coordinate recovery.

"I have been closely monitoring the situation all night and will continue to do so until full restoration is completed. I commit to keeping the nation advised and updated on this UNACCEPTABLE SITUATION."
