Successful Commissioning & Inauguration of Rangjung Mini Hydel Plant (2 x 1.1 MW)
Bhutan Automation & Engineering Limited is pleased to announce the successful commissioning and inauguration of the Rangjung Mini Hydel Plant (2 x 1.1 MW) on 4th August 2026. This achievement forms part of a broader upgradation project covering both the Gidakom and Rangjung Mini Hydel plants, delivered by BHUTAN AUTOMATION to the Operation and Maintenance Services Centre (O&MSC), DGPC.
Technical scope of the work covered:
- SICAM A8000 controllers deployed for the Unit Control and Common Control systems, with governor control logic developed and implemented within the A8000 platform
- HIPASE-PS protection relays for generator protection
- OPM Toolbox II and SCALA 250 for the SCADA screens and Operator Workstation
- Existing excitation system retained and integrated into the upgraded control architecture
The commissioning process presented several technical challenges, which were successfully resolved through the dedication of the on-site team and valuable support from the custodian plant, Kurichu Hydropower Plant.
BHUTAN AUTOMATION extends its sincere gratitude to the Operation and Maintenance Services Centre (O&MSC), DGPC, for their continued trust and partnership on this project.
This milestone reflects BHUTAN AUTOMATION's ongoing commitment to delivering reliable & technically sound engineering solutions for Bhutan's hydropower sector
