"The immediate report that we received from the CENACE (National Center of Energy Control) is that there is a failure in the transmission line that caused a cascade disconnection, so there is no energy service on a national scale," Public Works Minister Roberto Luque wrote on X.

Luque added, "We are concentrating all our efforts on resolving the problem as quickly as possible."

The blackout has paralyzed a major subway system in the South American country. There are reports that hospitals in major cities are without power. This comes months after Ecuadorean President Daniel Noboa declared a power emergency and ordered eight-hour nationwide rationing due to lower hydroelectricity power generation levels. 

Internet tracking website NetBlocks reports that Ecuador's national connectivity plunged to 44% shortly after the power outage.
