Overview
Rangjung Small Hydroelectric Power Plant is a 2.2 MW operational hydro facility in Bhutan. It contributes to the country's renewable energy portfolio, leveraging Bhutan's mountainous terrain for clean power generation.
Rangjung Small Hydroelectric Power Plant is a 2.2 MW hydroelectric facility located in Bhutan. As a small-scale run-of-river plant, it harnesses the flow of local rivers to generate electricity, supporting Bhutan's goal of carbon-neutral electricity production. The plant is operational and plays a role in the country's domestic power supply. Bhutan's power sector is dominated by hydropower, with the country exporting surplus electricity to India. Small hydro plants like Rangjung are part of a decentralized approach to electrify rural areas and reduce transmission losses. The plant's capacity of 2.2 MW places it in the small-scale category, typical for community-level projects in the region. Environmentally, the plant produces zero direct emissions, aligning with Bhutan's commitment to maintaining at least 60% forest cover and being carbon negative. Its small scale minimizes ecological disruption, though local aquatic ecosystems may experience altered flow regimes. The facility supports Bhutan's sustainable development priorities and energy security.
Environmental context
Bhutan's hydropower sector is a cornerstone of its carbon-negative strategy, with most plants being run-of-river to minimize reservoir impacts. The Rangjung plant's small capacity (2.2 MW) reduces its environmental footprint compared to large dams. However, hydroelectric projects can affect river flow and aquatic habitats. Bhutan's regulatory framework emphasizes environmental impact assessments and sustainable operations to balance energy needs with ecological preservation.
Frequently asked questions
Rangjung Small Hydroelectric Power Plant is located in Bhutan, with coordinates approximately 27.3567° N, 91.6497° E. It operates as a small-scale hydroelectric facility.
The plant has a capacity of 2.2 megawatts (MW), making it a small hydroelectric facility typical for rural electrification in Bhutan.
Rangjung is a run-of-river hydroelectric power plant, which uses the natural flow of water without significant storage, minimizing environmental impact.
Bhutan's hydropower sector is regulated by the Bhutan Electricity Authority and the Department of Energy. Projects must undergo environmental impact assessments and adhere to sustainable development principles, including maintaining forest cover and carbon neutrality.
Small hydro plants like Rangjung have lower environmental impact than large dams, but can still affect local river ecosystems. Bhutan's policies require mitigation measures such as fish ladders and minimum flow releases to protect aquatic life.
