Primelectric Benchmarks Korea’s Smart and Reliable Power Network
Everyone values reliable electricity, especially when it runs smoothly without any interruptions. Primelectric knows how essential this is for daily life, so the company looks for new ideas from around the world to improve its service. Recently, Primelectric sent a team to Seoul, South Korea, to learn from one of the world’s most advanced power distribution systems.
This visit shows Primelectric’s dedication to improving standards and providing better power services to communities throughout the Philippines.

Studying the Best in Power Distribution
Primelectric President and CEO Roel Castro led the benchmarking trip. Along with other company officials, he visited the Transmission and Distribution Headquarters of the Korean Electric Power Corporation, or KEPCO. KEPCO is known worldwide for its high standards in power transmission and distribution efficiency.
During the visit, KEPCO shared important performance numbers that show why it is a global leader. The company keeps system loss at just 3.53 percent and has a system average incident frequency index of only 0.6 percent each year. This means power interruptions are very rare, so businesses and households can count on a steady supply of electricity.
Technology That Keeps the Lights On
South Korea’s power system is reliable because it uses modern technology. Primelectric officials had the opportunity to see the equipment and facilities that help KEPCO achieve such strong results.
Right now, 12.3 percent of South Korea’s distribution lines are underground, mainly in commercial areas where safety and reliability matter most. All lines are fully insulated to lower risks and boost efficiency. The network also uses thousands of automatic circuit reclosers, which can restore power in as little as one second after a problem is found.
These technologies help prevent small problems from causing long power outages. For consumers, this means fewer disruptions and a more reliable power supply.

Smart Substations and Digital Control Systems
Another important lesson from the visit was seeing how KEPCO uses unmanned substations and digital systems. Primelectric’s team observed that substations, switches, control panels, and automatic circuit reclosers are all remotely monitored and controlled.
This kind of digital system lets teams respond faster and manage the network more accurately. It also reduces the need for workers to be on-site, making things safer and more efficient. For Primelectric, these ideas can be used to improve local operations in the Philippines.
Maintenance Without Interrupting Consumers
One of KEPCO’s most impressive practices is live line maintenance. This method lets technical teams perform maintenance work without interrupting customers’ electricity.
For customers, this means fewer power interruptions during scheduled maintenance. It also shows how good training and strong safety procedures can really improve service quality.
Putting Safety First at Every Level
In addition to advanced systems, Primelectric officials were also impressed by KEPCO’s strict safety standards. They saw that safety is a top priority for linemen and technical staff, with special protective gear and clear rules in place.
This strong safety culture makes sure that workers are well protected while they provide reliable power to customers. It shows that improving power distribution should never compromise worker safety.

Shaping the Future of Power Distribution in the Philippines
CEO Roel Castro said that what stood out most during the visit was not only the technology, but also the culture behind it. KEPCO’s work demonstrates a strong commitment to efficiency, reliability, and safety. Primelectric aims to bring this same approach to its service areas.
Primelectric plans to send its engineers to the KEPCO Academy so they can get hands-on experience with modern systems and top-quality equipment. This will help speed up the use of new technologies in Primelectric’s operating units, such as MORE Power, Negros Power, and Bohol Light.
Turning Global Insights into Local Improvements
Now that the team is back in the Philippines, Primelectric is working to turn what they learned into real improvements. The company will introduce these new practices step by step, making sure they fit well with current systems.
This benchmarking effort is an important step toward building a stronger and more reliable power distribution sector. By learning from global leaders like KEPCO, Primelectric is getting closer to its goal of providing consistent, efficient, and consumer-focused power services for Filipino communities.
