The National Grid Corp. of the Philippines (NGCP) has improved the reduction of frequency of tripping (FOT) on the back of “continuous upgrade, expansion and reinforcement” of their facilities.
“NGCP is pleased to report that from 2009 to the present, it has consistently complied with, if not exceeded, the performance targets set upon by ERC,” the grid operator said.
“Many technical changes have been implemented to systematically improve operations to build a stronger power grid. Improvements on corporate governance also resulted in more efficient and streamlined operational practices,” they added.
FOT is a performance indicator that measures that amount of times high-voltage transmission lines went under forced outages for every 100 circuit kilometers (ckm). This ensures there will be minimal power interruptions and allows transmission system operators to monitor and improve facilities.
NGCP said it cut down the FOT to 1.138 for Luzon, 0.5168 for Visayas, and 0.86 for Mindanao this year. This equates to a 73-percent improvement for Luzon, 86 percent for Visayas and 67 percent for Mindanao since 2009.
System Availability (SA) ratings in Luzon improved to 99.5702 percent this year from last year’s 99.4125 percent. The Visayas and Mindanao grids remained at 99.8013 percent and 99.732 percent, respectively. These ratings measure the availability of the entire transmission system operating normally.
“Our customers can expect that NGCP will continue to look for opportunities to maintain or even surpass its yearly performance, and push further its level of excellence, to provide better services to customers,” NGCP said.
