Shortly after midday, a loud explosion was heard at the Good Hope Substation on the East Coast of Demerara, operated by Guyana Power and Light Inc. (GPL). The substation, a key interconnection point between the Demerara and Berbice systems, went offline immediately after the blast. Investigations found smoke coming from the main breaker panel in the switchgear room. The sudden loss of the substation destabilised the national grid, causing multiple feeders to trip.

GPL began incremental restoration efforts and restored power to most affected areas within about an hour, though customers along the East Coast Demerara corridor from Success to Hope remained without electricity at the time of reporting. A mobile substation was deployed to Good Hope as a temporary measure while engineers assessed the damage and planned repairs.

GPL stated the explosion and smoke originated from the main breaker panel in the substation switchgear room. Commentators cited in the report noted that the transmission and distribution system remains prone to disturbances despite past investment, though this is a general observation rather than a confirmed technical cause.

  1. A substation that links two grid regions needs backup paths or fast transfer schemes, because loss of the main breaker panel removed supply from both Demerara and Berbice systems.
  2. Mobile substations should be kept ready for critical sites, because the unit deployed at Good Hope allowed most customers to be restored within an hour.
  3. Switchgear rooms at interconnection substations require targeted inspection of breaker panels, because the explosion and smoke started in the main breaker panel.
