Irrigation Engineering Questions and Answers – Hydro Electric – Water Power Development

This set of Irrigation Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Hydro Electric – Water Power Development”.

1. As per estimate made by the Central Electricity Authority, the potential of the country is accessed at 84 GW at load factor value of _________________
a) 40%
b) 60%
c) 80%
d) 20%

Explanation: This equivalent to about 440 billion units + KWh of annual energy generation at a power factor of 0.6. 60% load factor means that the installed machines are run on an average to give output capacity equal to 60% of the station capacity. Machines will not always work at the installed capacity but on an average of 60% of this capacity.

2. The first power station of India was installed at _________________
a) Mysore
b) Bombay
c) Darjeeling
d) Bangalore

Explanation: The first hydropower station in India dates back to the year 1897 when a small power station of 200 KW capacities was constructed in Darjeeling. Then it was followed by a 50 MW Tata Electric project of Bombay in 1914.

3. What is the correct expansion of DAE?
a) The Department of Atomic Energy
b) The Discipline of Atomic Energy
c) The Division of Atomic Energy
d) The Domain of Atomic Energy

Explanation: This department directly runs under the Prime Minister of India with headquarters in Mumbai, Maharashtra. The main aim of the department is to increase nuclear power production from 3% to 8% of the total electricity generation in the next 15 years.

4. In India, the nuclear power generation is about ____________ of the total power generation.
a) 3%
b) 4%
c) 5%
d) 6%

Explanation: The nuclear power generation is only about 3% of the total power generation including hydropower, thermal power, nuclear power, etc. The Indian Department of Atomic Energy is planning to boost its generation in the next 15 years from 3% to 8% of the total electricity generation.

5. Which one is the first nuclear power plant in India?
a) Tarapur atomic power station
b) Kaiga atomic power station
c) Rawatbhata Atomic power station
d) Narora atomic power station

Explanation: Tarapur Atomic power station 320 MW is located in Tarapur, Maharashtra and it was the first commercial nuclear power station. The construction began in 1961 and went operational in 1969. It has two 160 MW water boiling reactors.

6. Convert the hydropower potential of 84 GW at 60% load factor into Trillion watts hour.
a) 441 TWh
b) 735 TWh
c) 553 TWh
d) 345 TWh

Explanation: 1 TW (Trillion watt) = 1000 GW (Giga watt)
84 GW is equivalent to = 84 x 365 x 24 = 735,840 GW hour
At 60 % load factor = 735,840 x 0.6 = 441,504 GW hour = 441 TWh or 441 b KWh.
