Working on The Bacolod-Silay 69kV Line Upgrade
Ever since Negros Power took over, teams of linemen had been working on the Bacolod-Silay 69kV line because of its massive coverage. The project involved inspecting, replacing, and upgrading 266 structures spanning seven key segments, covering a total of 29.87 circuit kilometers!
Foremost, the outdated and frequently failing porcelain insulators were replaced with durable polymer insulators, eliminating a long-standing cause of frequent power interruptions.
“Before this rehabilitation, broken insulators were causing two to three unscheduled outages weekly. Today, I am proud to report that there have been zero insulator failures since December 2024,” said Roel Z. Castro, President and CEO of Negros Power during his report to consumer stakeholders recently. “This accomplishment shows our commitment to reliability and our investment in building a better energy future for Negros.”
The Challenges
One of the major challenges faced was terrain accessibility. Linemen had to traverse off-road areas, as 103 of the 277 poles (37.18%) are located in sugarcane fields or passing through rivers, requiring crews to manually access and repair them.
Despite the logistical hurdles, the project was 100% accomplished, thanks to the dedication of Negros Power’s line workers and engineers.
“This is not just an upgrade. This is a clear message to every consumer that Negros Power is serious about system reliability, safety, and long-term progress,” added Castro.
Frank Carbon, Co-Chair of Energy and Power Committee of PCCI for Visayas and former Bacolod Chamber of Commerce and Industry President, attended the meeting and reacted, “Stable and modern power is essential to economic growth. The direction Negros Power is taking is exactly what Bacolod and the rest of Central Negros need.”
