WILLEMSTAD – The island-wide blackout that affected Curaçao on August 27, 2025, was caused by a complex combination of technical circumstances and was not the result of the deficiencies identified during earlier investigations into the island's electricity system, according to the Regulatory Authority of Curaçao (RAC).
RAC released the findings following an independent review conducted with international electricity experts from ENGIE/Laborelec.
According to the report, the August 2025 outage resulted from an unfortunate sequence of technical events rather than from the shortcomings previously identified after earlier blackouts. The regulator noted that most of those earlier deficiencies have since been corrected through improvements implemented by Aqualectra.
The investigation states that concrete measures have already been introduced to reduce the likelihood of a similar incident occurring again.
While RAC emphasized that no electricity system can completely eliminate the risk of outages, it said the improvements now in place significantly reduce both the probability of major disruptions and their potential impact should they occur.
The regulator also warned that operating Curaçao's electricity grid is becoming increasingly complex, particularly as the island continues its transition toward more sustainable energy sources.
According to RAC, maintaining a stable and reliable electricity supply will require continuous investment, modernization and oversight as renewable energy becomes a larger component of the national grid.
RAC said it will continue supervising the electricity sector through transparent regulatory oversight and regular evaluations of Aqualectra's operations.
The authority has published the complete investigation report, including its technical findings and recommendations, on its official website.
