THE National Grid Corporation of the Philippines (NGCP) has called on generation companies to synchronize their systems to that of the grid operator to avoid the repeat of the power interruption on Nov. 15 that left parts of Metro Manila without electricity for at least an hour.

“NGCP is urging power plants and distribution utilities to coordinate with us and agree on a uniform protection setting which shall be strictly adhered to by all power industry participants,” Cynthia P. Alabanza, NGCP spokesperson, said in a text message.

On Nov. 15, power went out in some parts of Metro Manila and some areas in Luzon. The outage lasted for about an hour and 20 minutes — from 7:30 p.m. onwards in some parts of the capital.

“Our settings are not compatible with theirs,” she earlier told reporters. “I don’t want to say that it’s their fault, and I’m not ready to say that it’s the system’s.”

As reported by NGCP, eight large power plants tripped on that day. They have a total capacity of 2,407 MW.
