Electricity service was already restored for multitude of affected consumers in the Visayas grid, but investigation on the cause of the “Chinese New Year blackouts’ in the grid is still ongoing.

According to NGCP spokesperson Cynthia Alabanza, the grid operator already “completed the restoration of power transmission in the Visayas grid as of 9:09 a.m. on Friday (February 20).”

But she averred the “analysis of the root cause of the loss of power is ongoing.” A meeting was also scheduled yesterday purportedly to discuss initial findings.

The system operator has reported that “partial loss of power occurred 1:45 a.m. on Thursday in Cebu, Bohol, Leyte and Samar islands.”

Following the incident, “restoration activities immediately started in Cebu, followed by the other islands,” the grid operator has emphasized.

Energy Secretary Carlos Jericho L. Petilla has indicated in television interviews that the trigger to the blackouts was not immediately known, but he had ordered a probe on the matter.

Rotating brownouts or blackouts are currently the most despised terms among electricity consumers, especially since such threats are anticipated to strike at the onset of scorching summer months.

There had been several incidents in the past when dreaded blackouts ensued due to array of factors – ranging from trifling to major technical glitches in the system.

The wallop of super typhoons and other extreme weather events had also downed power utilities in the past resulting in longer duration of power interruptions.

In the case of the Visayas blackouts on Thursday though, it was qualified by the energy department that the cause of supply disruption was on the transmission component of service delivery, and not on lack of supply in the generation segment.
