OUR PROJECTS

Basochhu Hydropower Plant

The Contract for Upgrade of Switchyard SCADA and Protection Relays of BHP was signed with Druk Green Power Corporation on 07 August 2019. The 220/66 kV switchyard of BHP, which first interconnected the eastern and western girds of Bhutan at 220 kV voltage level, will be supplied with state-of-the-art control and protection systems. In addition, protection relays in the two powerhouses will be replaced with the latest digital IEDs.

The execution of the project is currently in full swing. The retrofitting of the generator protection relays with the latest HIPASE-P IEDs have been completed at both the upper and lower power plants. The erection and commissioning of the SCADA, and Control and Protection panels at the switchyard are scheduled to be completed by the end of 2021.

Kurichhu Hydropower Plant

The Contract for modernization of the 60 MW Kurichhu Hydropower Plant (KHP) was signed with DGPC on 12 September 2018. Located in the eastern part of Bhutan, KHP was commissioned between 2001 and 2002. The hydropower plant consists of four Kaplan-turbine generating units with installed capacity of 15 MW each.

The scope of the Contract comprised of the replacement of the existing SCADA System including Unit, Dam, Common Auxiliary, & Switchyard Controls, and Governor & Excitation Systems. The Contract also included the replacement of some related field instruments.

The refurbishment contract was successfully completed in December 2020. In addition to an integrated control and monitoring solution, the implementation includes advanced joint control features.

Punatsangchhu-II Hydroelectric Project

The Contract for Design, Manufacture, Supply, Handling, Storage, Transportation from storage site to place of installation, Erection, Testing, Commissioning and Handing over of complete Computerized Control System & Protection System of the 1020 MW PHPA-II was signed on 31 December 2018.

Located in the central part of Bhutan, PHPA-II is an intergovernmental project between the Governments of Bhutan and India. The hydropower project will consist of six Francis-turbine generating units with installed capacity of 170 MW each. The completion and handing over of the project are scheduled towards the beginning of 2023.

Bhutan Power Corporation limited

Awarded on 03 June 2020, this was the first project beyond the hydropower sector.  The contract covered supply, installation, testing, and commissioning of SCADA systems at 132 kV Tintibi, Gelephu, Yurmoo, and 66 kV Olakha substations under BPC. The implementation of SCADA at Gelephu substation was later changed to Lobeysa substation.

The SCADA systems offered at the substations are based on the state-of-the-art 250 SCALA. The work consists of integration of IEDs and energy meters from various manufacturers with the 250 SCALA on the latest industry standard communication protocol for substations IEC 61850. 

The SCADA systems were successfully commissioned at all the four substations in April 2021.

Punatsangchhu-I Hydroelectric Project Authority

The Contract for Design, Manufacture, Supply, Handling, Storage, Transportation from storage site to place of installation, Erection, Testing, Commissioning and Handing over of complete Computerized Control System & Protection System of the 1200 MW PHPA-II was signed on the auspicious day of 30 May 2021.

Located upstream of PHPA-II, PHPA-I is also an intergovernmental project between the Governments of Bhutan and India. The hydropower project will consist of six Francis-turbine generating units with installed capacity of 200 MW each. The completion and handing over of the project are scheduled towards the end of 2023.
