Druk Green Power Corporation Ltd. (DGPC), as the single entity representing the Royal Government of Bhutan’s interest in the hydropower sector, is expected to play a key role in accelerating Bhutan’s hydropower development, and the operation and maintenance of the existing hydropower plants. A very important mandate of DGPC is to build capacity in the water-to-wire business in hydropower sector. Therefore, in the pursuit to fulfil its mandate, one of the initiatives taken by DGPC was the establishment of the four Centres of Excellence (CoEs), between 2010 & 2013 to contribute towards fulfilling the shortages of a team of experts who can responsibly build highly specialised skills and undertake specialised works which otherwise are dependent on external expertise. The existing four CoEs are:

  1. Centre of Excellence for Dielectric Material Analysis (CoEDiMA) in Chhukha Hydropower Plant
  2. Centre of Excellence for Vibration and Thermographic Analysis (CoEVaTA) in Chhukha Hydropower Plant
  3. Centre of Excellence for Control & Protection (CoECaP) in Tala Hydropower Plant
  4. Centre of Excellence for Gates and Instrumentation [civil structure] (CoEGIcs) in Chhukha Hydropower Plant

With the experience gained from the existing CoEs and also to provide impetus to the existing CoEs so as to focus more on the research – oriented services, Hydropower Research & Development Centre (HRDC) was established in 2015 by merging the four existing CoEs. Further, considering the future growth and expansion of its services, the base of the HRDC was shifted from Chhukha to Rinchentshe in early 2018 and also established as an independent Profit Centre.

Currently, HRDC has a trained and experienced professionals, who have been certified by reputed institutions to undertake special testing and diagnostic jobs using state-of-the-art testing equipment in all hydropower plants under DGPC, and also offer such professional services to industries in Bhutan and neighbouring places in India. Further, HRDC is also involved in sharing its experiences and competencies by imparting training and participating in international events by publishing papers and professional engagement.
