Belize Electricity Limited (BEL) technicians were working late Sunday to fix damaged equipment at the company's Westlake Substation.

A brief statement put out by the state-owned company said that the damaged equipment was the cause of an "unplanned power interruption" which plunged the Cayo, Stann Creek and Toledo districts into blackout.

The blackout struck at 3:35 pm and it took roughly 3 hours for BEL to fully restore power to all the affected areas.
