The correct answer is: A. Arwal
Agnoor Hydroelectric Project is a run-of-the-river hydroelectric project located on the Agnoor River in the Arwal district of Bihar, India. The project has an installed capacity of 100 MW and was commissioned in 2006.
The project consists of a dam, a power house, and a transmission line. The dam is a 30-meter-high concrete gravity dam with a crest length of 250 meters. The power house is located at the foot of the dam and has four 25 MW Francis turbines. The transmission line is a 400 kV double-circuit line that connects the power house to the national grid.
The Agnoor Hydroelectric Project is a major source of power for the state of Bihar. The project has also helped to improve the irrigation facilities in the region.
