Question

At which place a geothermal energy plant has been commissioned?

• A. Manikaran
• B. Khetri
• C. Katni
• D. Ratnagiri

Hint:

Prominent geothermal energy sites in India:
1. Manikaran (Parbati Valley, Himachal Pradesh).
2. Puga Valley (Ladakh).

Answer 1

The Correct Option is A

Concept:
Geothermal energy is the thermal energy generated and stored inside the Earth's interior crust.
Magma heated groundwater rises toward the surface in the form of hot springs and geysers, creating steam that can be captured to turn turbines and generate clean, renewable electric power.
In India, exploration and experimental commissioning of geothermal pilot power plants have been undertaken at strategically identified hot-spring sites.

Step 1: Identifying the Commissioned Pilot Plant:
Manikaran is located in the Parbati Valley of the Kullu district in Himachal Pradesh.
It is famous for natural geothermal hot springs where groundwater reaches boiling temperatures naturally.
The Geological Survey of India (GSI) and the National Hydroelectric Power Corporation (NHPC) successfully set up an experimental geothermal power plant at Manikaran.
Another notable geothermal project area identified in India is the Puga Valley in the Ladakh region.

Step 2: Evaluating the Alternative Options:
Khetri in Rajasthan is renowned for underground copper mining operations.
Katni in Madhya Pradesh is widely celebrated for its extensive bauxite, limestone, and marble reserves.
Ratnagiri in Maharashtra is recognized for coastal ports, horticulture (Alphonso mangoes), and bauxite deposits.
Final Answer:
Consequently, an experimental geothermal energy plant has been commissioned at Manikaran.
