"We have made a request to commerce and steel ministries that anti-dumping duty reference price be fixed only for the investigation period 2015-16 as during that period, steel price and cost of production were different than what it is today," Rao said. At Dolvi, we have approvals to double the capacity to 10 mt.The national steel policy envisages to increase installed capacity to 300 mt by 2030 from the current 128 mt." Steel demand grew 3."We have environmental clearances to increase the capacity at the Vijaynagar plant from 12 mt to 16 mt.Claiming that his company has one of the lowest cost per tonne, Rao said, "to set up a greenfield steel project today it costs Rs 6,000-7,000 crore per million tonne.5 per cent in fiscal 2017 and JSW expects demand growth to expand 1..2-1.If the country builds wholesale carbon steel nuts 300 mt capacity by 2030, we would like to plan accordingly to maintain our 15 per cent share, which will be 40-45 mt," JSW Steel joint managing director & group CFO Seshagiri Rao told PTI.Mumbai: Leading alloy-maker JSW Steel is planning to increase its manufacturing capacity to 40-45 million tonne by 2030 from the present 18 million tonne. So, that is the kind of capex we will require to create an incremental 22 mt capacity."Today we have 18 mt installed capacity which is 15 per cent of the national steel manufacturing capacity of 128 mt. This means we have the approval to increase our capacity to 27 mt from the present 18 mt," Rao said.3 times of GDP growth if investments pick up.Commenting on the government seeking suggestions from the industry over anti-dumping duty imposed last year, Rao said the duty generally is a medium term for five years. But we spend only almost half of this at Rs 3,000-3,500 crore per mt. This will take demand growth to 9-10 per cent, implying an incremental demand of 9-10 mt per annum
