PT Thredio Engineering has once again demonstrated its expertise in the field of control system integration through the implementation of an "Automatic Generation Control (AGC)" project at the Ulubelu Geothermal Power Plant in Lampung. This marks the second AGC project undertaken by PT Thredio Engineering in the geothermal power generation sector, following the successful implementation of AGC at Unit 1 of the Darajat Geothermal Power Plant.
The project at the Ulubelu Geothermal Power Plant began with the installation preparation and panel fitting phase, which took place from 11 to 26 September 2026. This phase involved various technical preparations to ensure that all equipment and supporting systems could be integrated with the existing power plant control system.
Moving into the testing phase, PT Thredio Engineering carried out Session 1 of the AGC system testing at Ulubelu Geothermal Power Plant Unit 2 on 8 - 9 October 2026. This testing was conducted to ensure the system functions in accordance with the plant's operational requirements and supports automatic power control. Subsequently, on 26 October 2026, the project entered Session 2, which focused on testing the AGC system at Ulubelu Geothermal Power Plant Unit 1.
The implementation of AGC plays a vital role in supporting power plant operations, particularly in regulating power output to meet the needs of the electricity system. Through this system, generation control can be carried out automatically by PLN via the Sumatra Load Dispatch Centre (UP3BS). This aims to maintain the stability of the electricity grid frequency and enhance the effectiveness of power plant control in the event of disruptions to the electricity grid system in the Sumatra region.
PT Thredio Engineering's involvement in this project also demonstrates the company's ongoing expertise in managing control system integration within the energy sector. Building on its experience from the previous AGC project at the Darajat Geothermal Power Plant Unit 1, Thredio continues to develop its technical capabilities to deliver automation solutions tailored to the specific needs and characteristics of each power plant.
Through this AGC project at the Ulubelu Geothermal Power Plant, PT Thredio Engineering hopes to continue contributing to the development of Indonesia's electricity infrastructure, particularly within the geothermal energy sector. This achievement also marks a further step for the company in strengthening its role as a provider of control system integration and automation solutions for the energy industry.
Looking ahead, PT Thredio Engineering remains committed to delivering reliable and innovative technological solutions to support power plant operations and the development of renewable energy in Indonesia.
