Question

Which hydroelectric project does not belong to Tamil Nadu?
A. Kundah
B. Kadamparai
C. Aliyar
D. Idukki

Answer 1

Hint: It is the greatest hydroelectric Project in Kerala. It includes three dams at Idukki, Cheruthony, and Kulamavu and related frameworks. The Idukki Dam is a dam developed over the Periyar River in Kerala.

Complete step-by-step solution:
The Idukki Dam is a twofold ebb and flow Arch dam developed over the Periyar River in a restricted canyon between two rock slopes privately known as Kuravan and Kurathi in Kerala, India. At $168.91$ meters ($554.2$ ft), it is one of the most raised bend dams in Asia. It is built and claimed by the Kerala State Electricity Board. It underpins a 780 MW hydroelectric force station in Moolamattom, which began producing power on 4 October 1975. The dam type is a solid, twofold bend illustrative, meager circular segment dam. This dam was built alongside two different dams at Cheruthoni and Kulamavu. Together, the three dams have made a counterfeit lake that is 60 km2 (23 sq mi) in the region. The set-aside water is used to convey power at the Moolamattom Powerhouse, which is arranged inside near to unpleasant clasps. The Government of Canada helped in the structure of the dam with long haul credits and awards. Constructing a dam for the power age was first imagined in 1919 in a report put together by Italian architect Jacob to the Travancore government, which was dismissed. According to history, Shri Chemban Karuvellayan Kolumban, the head of 'Oorali' race during 1922, demonstrated the path to the Malankara Estate Superintendent W.J.John and his companion AC Thomas Edattu, who were on chasing excursion to woods close to the current Arch Dam. After hearing the legend of Kuravan and Kurathi Hills, Thomas dazzled by seeing a water stream between the mountains; recommended the spot reasonably for an Arch dam. In 1932, W.J.John presented a report to the Government of Travancore on the chance of developing a dam at Idukki for Power Generation. The Project bridles a significant part of the force capability of Periyar, the biggest stream in Kerala, by the formation of a repository of 2 Billion Tons limit, redirection of waters in this way seized through a water conductor framework comprising of a forced passage and two underground weight shafts to an underground force to be reckoned with arranged in Moolamattom. The introduced limit of the Power House is 780 MW comprising 6 Units of Pelton-type turbines with a force age limit of 130 MW each. The controlled waters of Periyar fall through a drop of about $669.2$ m (2,196 ft) while creating power in the underground force to be reckoned with. The produced power is given to two substations. One twofold circuit line to Kalamassery; one single circuit line to Tamil Nadu; One single circuit line to Pallom, 3 feeder narrows for future.

Thus, option (D) is correct.

Note: Idukki Dam is $168.91$ m ($554.2$ ft) tall, built between the two mountains - Kuravan Mala (839 m (2,753 ft)) and Kuravathimala (925 m (3,035 ft)). The length of the dam is $365.85$ m ($1200.3$ ft). It has a width of $7.62$ m ($25.0$ ft) in the top and $19.81$ m ($65.0$ ft) in the base.
