Power outages impact nearly 2 million residents, according to Meralco

Nearly two million residents in Luzon experienced power interruptions last Saturday due to supply deficiency, according to electric power distributor Manila Electric Co. (Meralco).

In a statement released on Sunday, Meralco explained that manual load dropping (MLD) or rotational power interruptions lasting an average of 1.5 hours were implemented in parts of Batangas, Bulacan, Cavite, Laguna, Metro Manila, Pampanga, Rizal, and Quezon province.

MLD is used to limit demand when electricity generation is insufficient or contingency reserve is zero. Meralco spokesperson Joe Zaldarriaga stated, “Due to the significant supply deficiency, rotational power interruptions had to be implemented across Luzon, including in Meralco’s service areas, to manage the current system condition.”

Services were fully restored by 11:47 p.m. on Saturday, Meralco confirmed. The National Grid Corporation of the Philippines placed the Luzon grid under red alert on Saturday, indicating that generated electricity was not sufficient to meet consumer demand.

Meralco reported that commercial and industrial customers de-loaded a collective capacity of more than 200 megawatts on Saturday, helping to alleviate the impact of the red alert that lasted for almost half of the day.

“We sincerely apologize to our customers for the inconvenience caused by this challenging situation. We continue to proactively exhaust all demand-side management efforts to help minimize, if not avert, power interruptions,” Zaldarriaga expressed.

As of Sunday, the Luzon grid was under normal condition with an available capacity of 14,276 MW and a peak demand of 10,763 MW, according to NGCP’s 10 a.m. update.
