Davao Light and Power Company explains total power outage that hit its entire franchise 1:01 a.m. on Easter Sunday. This happened after supply from the National Grid Corporation of the Philippines (NGCP) was suddenly cut-off.
The outage, according to the transmission operator, NGCP has affected also the entire Mindanao island.
Davao Light immediately implemented its contingency measures. At around 1:00 a.m., power supply was received from its embedded power sources: the Hedcor’s Sibulan Hydro Plant and the standby Bajada Diesel Power Plant. The power from the latter plant was served prioritizing key service providers, such as hospitals.
After synchronizing power with NGCP, gradual restoration process started at 4:29 a.m.
This has restored some areas within the Davao Light franchise namely Ecoland, Downtown, Buhangin, Lanang, Panacan and DCWD sump pumps in Talomo.
By 6:25 a.m., only areas from Bunawan going to Panabo up to Sto. Tomas remained to have no power.
Finally, power in all areas within the Davao Light franchise was fully restored at 7:17 a.m.
An advisory received from NGCP through a text message said that it is working to restore power transmission services to affected customers in Mindanao.
As of press time, Davao Light is still awaiting for the advice from NGCP as to the cause of the said total blackout.
In view of the unstable supply being experienced in the Mindanao transmission grid, Davao Light is closely monitoring the situation. Hence, Davao Light is constrained to implement de-loading of certain feeder lines to avoid its distribution network system as well as the Mindanao grid from total collapse. De-loading results to power interruptions on certain areas connected to the de-loaded feeder lines. This explains the isolated interruptions that continued even after the power was initially restored at 7:17 a.m.
Although the power outage was beyond Davao Light’s control, it expressed its deep apology to its customers for the inconvenience that they experienced.
