Druk Green Power Corporation (DGPC) is a state-owned enterprise of Bhutan responsible for operating and managing the country's major hydropower plants. Established in 2008, DGPC is Bhutan's largest revenue-generating entity and plays a central role in the national economy through the export of surplus electricity, primarily to India.
Druk Green Power Corporation Limited (DGPC) is the largest state-owned enterprise in Bhutan, responsible for the operation and management of the country's major hydropower generation facilities. Established on 1 January 2008 through the consolidation of several previously independent hydropower project authorities, DGPC was created to bring Bhutan's most important revenue-generating assets under a single, professionally managed corporate entity. The corporation operates under the Druk Holding and Investments (DHI), the investment arm of the Royal Government of Bhutan, and is headquartered in Thimphu.[1]
Hydropower is the backbone of the Bhutanese economy, accounting for a significant share of government revenue, national GDP, and export earnings. Bhutan's mountainous terrain and abundant river systems provide an estimated 30,000 megawatts (MW) of hydropower potential, of which approximately 2,300 MW had been developed as of the early 2020s. DGPC manages the majority of this installed capacity and is therefore central to Bhutan's economic development strategy and its aspiration to become a net carbon-negative nation.[2]
Formation and Corporate Structure
Prior to DGPC's creation, Bhutan's major hydropower plants were each managed by separate project-specific authorities. The Chhukha Hydropower Corporation, Kurichhu Hydropower Plant authority, and Basochhu Hydropower Plant authority operated independently, leading to fragmented management and inefficiencies. In 2008, the Royal Government consolidated these entities into a single corporation — DGPC — to achieve economies of scale, standardise operational practices, attract professional talent, and improve corporate governance.[1]
DGPC is a fully government-owned company, with its shares held by DHI on behalf of the Royal Government. The corporation is governed by a board of directors that includes government appointees and independent professionals. It operates as a commercial entity with its own balance sheet and is expected to generate returns for the government while maintaining the highest standards of environmental stewardship and safety.
Hydropower Plants Under DGPC
DGPC operates and manages several major hydropower facilities, which together form the core of Bhutan's electricity generation infrastructure:
Tala Hydroelectric Project (1,020 MW): Commissioned in 2007, the Tala project on the Wang Chhu river is the largest operational hydropower plant in Bhutan and one of the largest in the region. Located in Chukha District, it was built with financial and technical assistance from the Government of India. Tala is a run-of-river scheme with an underground powerhouse and six 170 MW turbines. It generates the bulk of Bhutan's electricity exports to India.[3]
Chhukha Hydropower Plant (336 MW): Bhutan's first major hydropower project, commissioned in stages between 1986 and 1988. Located on the Wang Chhu river downstream of Thimphu, Chhukha was also built with Indian assistance and marked the beginning of Bhutan's emergence as a significant hydropower producer. The plant has four 84 MW turbines and continues to operate reliably after several decades of service.[4]
Kurichhu Hydropower Plant (60 MW): Located on the Kurichhu river in Mongar District in eastern Bhutan, this run-of-river plant was commissioned in 2002. It was the first major hydropower project in eastern Bhutan and plays an important role in regional electricity supply and grid stability.[5]
Basochhu Hydropower Plant (64 MW): A two-stage hydropower plant on the Basochhu river in Wangdue Phodrang District, built with Austrian development assistance. The upper stage (24 MW) was commissioned in 2001 and the lower stage (40 MW) in 2004. It was Bhutan's first hydropower project financed on a grant basis by a country other than India.[6]
Economic Significance
DGPC is Bhutan's single largest revenue generator. The corporation's revenues come primarily from the sale of electricity to India under long-term power purchase agreements and from domestic electricity sales to the Bhutan Power Corporation (BPC), which handles distribution within the country. Hydropower export revenues have historically accounted for approximately 20-30 percent of Bhutan's total government revenue and around 14 percent of GDP, making DGPC's operations critical to national fiscal health.[7]
The surplus electricity generated by DGPC's plants is exported to India through a bilateral arrangement that dates back to the 1974 Chhukha agreement. Under successive intergovernmental agreements, India has provided concessional financing for Bhutan's hydropower development in exchange for the right to purchase surplus electricity at agreed tariff rates. This arrangement has been mutually beneficial: Bhutan receives development financing and export revenue, while India obtains clean energy to supplement its growing electricity demand.
Environmental and Social Responsibility
DGPC has positioned itself as an environmentally responsible corporation, consistent with Bhutan's national commitment to environmental conservation and its constitutional mandate that at least 60 percent of the country's land area remain under forest cover. Hydropower is classified as a clean and renewable energy source, and Bhutan's carbon-negative status is largely attributable to the clean electricity generated by DGPC's plants. The corporation implements environmental management plans for each project, including measures for watershed protection, aquatic ecology monitoring, and community resettlement support.[1]
However, hydropower development has not been without social and environmental controversy. Dam construction has required the relocation of communities, alteration of river ecosystems, and clearing of forest land. DGPC works with government agencies and international partners to mitigate these impacts, though civil society organisations have occasionally raised concerns about the adequacy of compensation and environmental monitoring.
Future Development
Bhutan has ambitious plans to develop additional hydropower capacity, with several large projects in various stages of planning and construction. The Punatsangchhu-I (1,200 MW) and Punatsangchhu-II (1,020 MW) projects, along with the Mangdechhu (720 MW) project commissioned in 2019, represent the next wave of large-scale development. While some of these newer projects are managed by separate project authorities during construction, they are expected to eventually come under DGPC's operational management upon commissioning.[7]
DGPC is also exploring diversification into other renewable energy sources, including solar and wind power, as part of Bhutan's broader strategy to expand its clean energy portfolio and reduce seasonal dependency on hydropower, which is affected by monsoon cycles and glacial melt patterns influenced by climate change.
