Tripped transmission lines caused last week’s blackouts — Harjohn

The country’s power supply was disrupted on Wednesday January 7, due to tripped transmission lines which connect the Garden of Eden and Golden Grove substations, according to Deputy Chief Executive Officer of the Guyana Power and Light Company (GPL) Bharat Harjohn.

 He told this newspaper on Saturday that the tripped transmission lines, which were subsequently rectified by the utility company’s emergency team, had significantly affected the power generation capacity.

  “This sudden loss of power caused a cascading effect on the grid resulting in a shutdown of the Demerara-Berbice Interconnected System (DBIS),” Harjohn said.
