TNB Committed To Safe, Sustainable Maintenance Practices

JOHOR BAHRU, March 13 (Bernama) -- Tenaga Nasional Berhad (TNB) remains committed to ensuring that maintenance work is carried out safely, sustainably, and innovatively while delivering stable electricity supply to consumers.

In a statement, the utility company highlighted the use of the ‘live method,’ which enables maintenance work to be conducted without power interruptions as the approach minimises impact on users and optimises energy resource utilisation.

According to the statement, transmission tower inspections, known as ‘Tower Top Inspection’ (TTI), are conducted to ensure that critical components such as cross arms, insulators, and jumper wire lugs are in good condition.

“TTI is carried out using the ‘live method,’ without disconnecting the power supply. 

“This method allows engineering teams to systematically monitor the physical condition of transmission towers and ensure the durability of energy transmission infrastructure. From a sustainability perspective, scheduled maintenance helps prevent the need for emergency repairs,” the statement added.

TNB emphasised that all maintenance personnel must undergo specialised training before receiving clearance to climb transmission towers and that safety measures include having an assistant within visible range at all times, using complete personal protective equipment (PPE), including a double lanyard and a full-body harness.

“In addition, a backup fall arrest system must be installed before starting any work, and a daily safety briefing (Toolbox Talk) is conducted before each task to prioritise workplace safety.

“We also focus on the health and well-being of workers by ensuring that all technical staff receive regular safety training and are equipped with appropriate personal protective gear,” the company said.

TNB noted that maintenance work often involves hard-to-reach areas, whether by water or land, and poses environmental challenges, including encounters with wild animals such as wild boars and snakes, which add to the complexities of fieldwork.

“However, the use of drones in transmission tower inspections and maintenance enhances safety, efficiency, and data accuracy while reducing the risk of accidents. Drones allow inspections to be carried out without workers having to climb towers or enter hazardous areas.

“Additionally, inspections can be conducted more quickly without power disruptions, reducing system downtime. Equipped with high-definition (HD) cameras, drones also help detect minor damages and predict maintenance needs,” it added.

TNB  pointed out that this technology also reduces costs, minimises the need for manpower and heavy equipment, and supports sustainability by lowering carbon emissions and ecosystem disturbances. saying that this contributes to safer, more efficient, and more sustainable operations, aligning with the company's environmental, social, and governance (ESG) commitments.
