Question 1 of 10
1. Question
1 pointsThe Dorjilung Hydroelectric Power Project, recently seen in the news, is located in which country?
Correct
Answer: b
Explanation:
Tata Power Company Ltd recently said it has signed commercial agreements with Druk Green Power Corporation Ltd (DGPC) for the development of the 1,125 MW Dorjilung hydroelectric power project in Bhutan.
About Dorjilung Hydroelectric Power Project:
It is a planned 1125 MW run-of-river project situated in the eastern Lhuentse and Mongar Districts of Bhutan on the Kurichhu River, a tributary of the Drangmechhu that flows into India.
At a height of approximately 139.5 m, the concrete-gravity dam channels nearly 287 m3/s through a 15 km headrace tunnel to an underground powerhouse housing six Francis turbines, designed to generate around 4.5 terawatt-hours (TWh) annually.
At a total project cost of ₹13,100 crore, Dorjilung will be Bhutan’s second-largest hydropower project, and the largest Public–Private Partnership (PPP) hydro project ever undertaken in the country.
The project is financed by the World Bank.
In November 2024, Bhutan’s Druk Green Power Corporation (DGPC) signed an MoU with Tata Power Company Limited for the joint development of the project.
The Project will be implemented through a Special Purpose Vehicle (SPV), with DGPC and Tata Power holding equity shares of 60% and 40%, respectively.
The project is expected to be commissioned by early 2032.
Hence option b is the correct answer.

- It is among the earliest land plants and has colonised some of the harshest environments on the planet, including Antarctica, volcanic fields, and deserts.
- Types of Moss: Of the 10,000 and more types of mosses on the planet, there are three main types: peat moss, granite moss and true moss.
- Distribution: Mosses are distributed throughout the world except in salt water.
- Habitat: It is the small plant commonly found in damp, shady spots is already known for its resilience on Earth.
- Moss reproduces through spores, which are the equivalent to a flowering plant’s seed.
- Ecological Significance:
- Ecologically, mosses break down exposed substrata, releasing nutrients for the use of more-complex plants that succeed them.
- They also aid in soil erosion control by providing surface cover and absorbing water.
- They are important in the nutrient and water economy of some vegetation types.
- Mosses can be effective indicators of c02 emissions that pollute the air. They can also signal if an ecosystem has been damaged or harmed by acid rain.
