ADB Project No: 54142-002: Preparing Renewable Energy for Climate Resilience (conduct of studies to prepare three (3) Bhutan solar PV power plant sites)


This Technical Assistance (TA) aims to introduce solar PV technology at utility scale, which is a novelty and innovation to the hydropower-dominated power sector in Bhutan. Moreover, this TA will support further development of non-hydro renewable energy sources in the country by providing Bhutan’s utilities with important expertise in this field.

Following were the major scope of the assignment:

  • A pre-screening and pre-selection of the most suitable solar sites among Bhutan’s proposed sites, which range from potential installed capacities from 15 megawatts (MW) to 90 MW each;
  • Preparation of feasibility studies (the “Study”) for the three best-ranked sites;
  • Environmental and social due diligence;
  • Economic and financial due diligence; and
  • Preparation of cost estimates and bidding documents to enhance project readiness.
  • Conduct Thimphu Roof Top Solar Pilot (RTS)
