Which hydropower plant in Bhutan was inaugurated recently by Indian Prime Minister NarendraModi?

The correct answer is D) Mangdechhu Power Plant. Modi and Bhutan's Prime Minister jointly inaugurated the 720 MW Mangdechhu Hydroelectric Project in Trongsa district in August 2019, during his Bhutan visit. It was built by THDC India Ltd under the Indo-Bhutan cooperation framework.

• A) Chhukha: An older project (336 MW, commissioned in the 1980s with Indian support). It was not the 2019 inauguration.
• B) Dagachhu: A 126 MW project on the Dagachhu river, commissioned around 2019, but not inaugurated by Modi.
• C) Kurichha: A small 60 MW plant built decades ago, linked to Assam's power grid. It is not a recent inauguration.

The core concept is India-Bhutan hydropower cooperation, which is central to the bilateral relationship and to India's energy security and cross-border power trade. For Mains, it is a good example of how the India-Bhutan partnership works, from financing to the export of surplus hydropower.

Trap: Aspirants often pick Chhukha because it is the best-known and largest-named Indo-Bhutan project. Always check the year and the inaugurating authority, not just the project's fame.
