Lower employee benefits expense also helped in pushing the company's quarterly profit higher.
NTPC had a net profit of Rs 2,130.39 crore in the same period last fiscal.
The state-run power producer's total income in the third quarter of the current fiscal rose to Rs 16,529.55 crore, from Rs 16,244.41 crore for the three months ended December, 2011, it said in a statement.
The rise in net profit was mainly on the back of increased generation capacity, lower fuel costs as well as employee benefits expenses, a company official said.
In the first nine months of 2012-13, NTPC began commercial operations of 3,820 MW power generation capacity.
At present, NTPC has a generation capacity of 39,674 MW and it is expected to go up to 1,28,000 MW by 2032.
