Project Description

IFC proposes to provide a debt investment of US$20 million to Bhutan Power Corporation (BPC). BPC is a state-owned company in Bhutan, responsible for the transmission and distribution of electricity across the country. It is wholly owned by Druk Holding and Investments Limited (‘DHI’), the investment arm of the Royal Government of Bhutan, which operates on commercial principles. The investment will be utilized for: (a) upgradation of Thimphu transmission system, including upgradation of 220/66kV Semtokha Air Insulated Substation (AIS) to Gas Insulated Substation (GIS); and (b) integration of upcoming solar power generation capacity including construction of 220/33kV Tenchekha Pooling Substation (PS).
The conversion of AIS to GIS at Semtokha is expected to happen concurrently with decommissioning of the existing transformer at the existing substation (SS) site. The GIS SS will be compact (18 X 21 sqmt) and therefore require limited space within existing SS premises. The conversion will involve replacement of transformers and associated equipment like circuit breakers, lightning arrestor, bus bar, control panel, relay panel and insulator. The current outgoing peak load is 128 MW, which during the conversion of the AIS to GIS will be managed through Bhutan Power System Operator, including the Load Dispatch Centre, in accordance with the power system contingency plan to ensure effective peak load management from the substation. The overall timeline for completion of the process is approximately six months and will involve two separate contractors: one for civil work and another for the GIS installation. The GIS supplier will be responsible for transporting the GIS from India via the Phuentsholing border and installing it at the site. The GIS configuration has been selected based on the load-bearing capacity of the roads along the transportation route. The typical service life of a transformer is approximately 30 years; as the existing transformer is around 18 years old, it will be relocated to another substation for continued use.

BPC is an existing client of IFC. Information on the existing investment through BPC Transmission # 48965, committed in Sep 2025 is available at  HYPERLINK "https://disclosures.ifc.org/project-detail/SII/48965/bpc-transmission" https://disclosures.ifc.org/project-detail/SII/48965/bpc-transmission; and performance till date is satisfactory.

Overview of IFC's Scope of Review

IFC’s review of the investment focused on identifying the environmental, health & safety, and social risks and impacts of the proposed project, assessing existing gaps against the requirements of the IFC Performance Standards (IFC PS), and identifying specific mitigation actions to ensure compliance with the IFC PS. IFC E&S review specifically involved visit to the existing substations at Semtokha and Dechencholing and to the Tenchekha area, where the Pooling Substation (PSS) is proposed. The site visit included discussions with key stakeholders, including the BPC project teams, site level operation and maintenance (O&M) teams and representatives from the local administration including the GUP (Head) of Kawang Gewog (Block) in Thimphu Dzongkha (District). IFC held appraisal meetings with the senior leadership and functional teams of BPC in Thimphu, involving representatives from Environment, GIS & Survey section, Transmission Department, Distribution Department including the Electricity Services Division (ESD) and Corporate Services Department.
