General Introduction
VAL Alumina Refinery: 1 MMTPA
Expansion to 6 MMTPA
Expand the capacity of aluminium smelter by 13.5 LTPA with
Captive Power Plant of 5 x 135 MW (675 MW) capacity at
Jharsuguda, Orissa.
After expansion, the total capacity of smelter will be 16 LTPA and
1350 MW CPP.
Estimated cost, including environmental management of Rs. 593
crores = Rs.6,500 crores
