TALCHER SUPER THERMAL POWER STATION, STAGE-I
(2X500 MW) & STAGE-II
(4X500 MW)
NTPC Ltd., New Delhi has set
up a
coal fired Thermal Power Station at Kaniha ( Talcher ) in Angul District of Odisha, for supplying power to cater to the needs of Eastern
Region and Southern Region and other interconnected grids. The station comprises s ix unit of
500 MW and hence, the total capacity of
the
plant as on date is 3000MW ( Stage-I comprises 2 units & Stage-II comprises 4 units
)
Site Locations and Approach
The site is bound by Tikra
Nadi towards North and West, villages Gadashila and Rangabera
and Brahmani River
towards east and NH-200
