Iloilo City Mayor Jerry P. Treñas similarly pushed for an inquiry, including in the Senate, to hold the National Grid Corporation of the Philippines (NGCP) accountable for their “incompetence.”
“I am calling on our congressmen to initiate a congressional investigation of the incident since yesterday that has caused power interruption in Panay, Guimaras, and Negros. In the same way, I call on the Senate to do the same. NGCP holds a franchise from Congress and therefore is accountable to it,” Treñas said.
“Congress needs to investigate the matter and restudy their franchise. The national government through the DOE (Department of Energy), the ERC (Energy Regulatory Commission), and the President should use all the powers in their mandate to ensure that the transmission lines of NGCP should be improved at the earliest possible time,” the mayor stressed in a separate statement.
It is noted that power outages blanketed the region at around 3 p.m. on Jan. 2, which the NGCP – a privately owned corporation in charge of operating, maintaining, and developing state-owned power grid – blamed to a “multiple power plant tripping in Panay Island.”
“The unscheduled maintenance shutdowns of the largest power plants in Panay Island were the primary cause of the power interruption. We emphasize the need for improved planning to ensure sufficient generation per island, with a well-balanced mix of fuels and technology,” NGCP said in a statement on Jan. 3.
The DOE, on the other hand, reminded the NGCP to adhere to its responsibilities as System Operator (SO) in ensuring supply security and reliability of the country’s state-owned power grid, stressing that they are in a position to immediately coordinate with the power plants to ensure that their respective unit protection and control settings will not cause grid instability that could lead to blackouts.
“NGCP is in a position to anticipate system disturbance such as what happened yesterday, which unfortunately resulted in the isolation of Panay from the rest of the Visayas grid due to the simultaneous tripping of power plants that caused multiple power interruptions affecting other power plants and distribution utilities (DUs)," Energy Undersecretary Rowena Cristina Guevara said in a statement.
