The National Grid Corporation of the Philippines (NGCP) is looking at the possibility of upgrading key power lines’ threshold to sustain stronger winds after experiencing the effects of Typhoon Rolly.
The company is looking at uprating some lines to be capable of withstanding up to 315 kilometers per hour (kph) of wind.
“Rolly was a particularly strong typhoon so we’re studying upgrading the rating. We’ve begun doing (such projects) after Yolanda. The upper threshold of wind rating was at 180 kph but after Yolanda, we repaired them to have a wind rating of 240 kph to 280 kph,” said Cynthia Alabanza, NGCP spokesperson.
