THE National Grid Corp. of the Philippines (NGCP), the country’s sole power lines concessionaire, said on Monday it recently conducted a typhoon and flood drill at its San Jose del Monte, Bulacan, and Mexico, Pampanga, substations.
The NGCP said the drills were targeted to help find ways to speed up the power restoration process during actual emergencies.
The NGCP said both activities are part of its Integrated Disaster Action Plan (Idap), which aims to ensure the readiness of all power transmission facilities expected to be affected by the passage of typhoons and other disasters like heavy rains, floods, landslides, tornadoes, fires, earthquakes, volcanic eruptions and tsunami.
Henry Sy Jr., NGCP president and chief executive officer, said the Idap aims to protect not just power transmission facilities such as lines, posts and towers physically exposed to calamities, but also the lives of NGCP employees and the people living near its facilities.
The highlight of the typhoon drill included the hauling and installation of Emergency Restoration System (ERS) materials using a twin-engine Bell 412EP helicopter.
The ERS is, according to NGCP, designed to expedite the erection of by-pass transmission lines and restore interrupted electrical services in the shortest possible time.
For purposes of simulation, the NGCP said two different sets of ERS were erected during the drill, from 10:15 a.m. to 3 p.m., to restore the supposed three toppled towers along San Jose-Taytay 230-kilovolt (kV) lines.
Assembling an ERS involves setting up and installing foundation plates and its base, a sliding gin pole to be connected to the ERS assembly, ERS columns, temporary and permanent guy wires fastened to the columns, and post insulators. source
