PLTU Technology Increasingly Sophisticated, PLN Strengthens Operator Competencies

PT PLN (Persero), Indonesia's state electricity company, is investing in its workforce by strengthening the competencies of human resources crucial for the reliability of the national electricity system. The company is specifically focusing on training operators for advanced Ultra Super Critical (USC) technology coal-fired power plants (PLTU).

This strategic move is driven by the rapid evolution of power generation technology, which demands operators with highly specialized skills. PLN Pusdiklat (Center for Education and Training) organized a workshop on operating USC-type coal-fired power plants from June 10-12, 2026, at the PLTU Jawa 7 in Serang, Banten. The training is part of PLN's broader effort to equip operators to manage high-tech power plants safely, efficiently, and reliably.

General Manager of PLN Pusdiklat, Y Endah Cahyaningrum, highlighted the importance of simulator-based learning. "PLN Pusdiklat continuously promotes learning that is not only theory-based but also provides practical experience through simulations that closely resemble actual conditions," she stated. "By utilizing simulators, participants can understand operational processes, practice responding to various scenarios, and strengthen operational discipline and workplace safety culture."

The workshop covered essential topics, including the characteristics of once-through boilers, USC steam cycles, control philosophies, critical operating parameters, and the management of boiler, turbine, generator, and Balance of Plant systems. Participants also engaged in hands-on practice using an Operator Training Simulator (OTS) to simulate diverse operational conditions, from start-up and load raising to normal operations, basic fault handling, and shutdown procedures, all while adhering to safety protocols. This approach ensures operators gain comprehensive experience without disrupting actual plant operations, enhancing their readiness for real-world scenarios and supporting national energy security amidst rising electricity demands.
