Blackout in Bali on 2nd May 2025

With much attention in the past week being focused on the major blackout on the Iberian Peninsula in Europe, it’s worth noting that (closer to home for us in the NEM) there’s also been challenges in Bali, as noted here by Michael Caravaggio from EPRI:

Michael’s quick note on LinkedIn references the article ‘Bali Blackout: Power Failure Linked to Undersea Cable Fault Brings Island to a Halt’ in the Jakarta Globe, which notes:

‘A major power outage swept across the island of Bali on Friday afternoon, disrupting tourism, commerce, and public services. The blackout began around 3:00 p.m. local time and lasted for approximately two hours, with lingering effects still felt in several areas.

According to state utility company PLN Bali, the outage was triggered by a failure in the undersea power cable that connects Java and Bali. The disruption caused all power plants on the island to shut down simultaneously, resulting in a sudden and widespread blackout. PLN said the system is still undergoing stabilization and recovery, while some areas continue to report partial outages and equipment damage.’

 

… add one more to the mix of Significant System Incidents.

 

Let’s hope not one other occasion when we’re forced to play ‘Blackout Buzzword Bingo’?
