MAITHON HYDEL POWER STATION

Maithon Hydal Power Station is

located on the river Barakar 12.9

km above its confluence with the

Damodar near the border of

Dhanbad and Burdwan districts of

the state of harkhand and !estBen"al res#ectively. $he uni%ue

feature of this hydal #ower station

is that it is located under"round in

the left bank of the river and is thefirst of its kind in &ndia. $he Power

station has a total "eneratin"

ca#acity of '( M! with ) units of

2( M! each.



H; H=r?;$r Wr





PENSTOC+:&t is a closed conduit which connects the fore bay or sur"e tank to the scroll

case of the turbine.
