Our smelter in Hirakud, Odisha was set up by INDAL in 1959. It had an initial capacity of 10,000TPA and was backed by 55kA Horizontal Stud Soderberg (HSS) technology which depended on power from Burla Power House. However, with an increasing demand for power, a 67.5MW thermal captive power plant based on Circulating Fluidised Bed Technology was commissioned in September 1993. This helped the smelter gain a competitive edge in the market. The captive power plant subsequently expanded its capacity to 467.5MW.
Between 2006 and 2008, the Hirakud smelter transitioned to 85 kA prebake technology in a phased manner, making it the first smelter in India to have achieved this technological upgrade using the same infrastructural facilities. Later in 2013, a 235 kA Prebake Potline with a 52KTPA capacity was added. Currently, the smelter has a total production capacity of 216,000TPA.
The primary raw material for the smelter, alumina, is sourced from our Muri and Utkal refineries. The smelter supplies its primary aluminium output to our downstream facilities, mainly Belur, Taloja, Alupuram, Mouda and Hirakud FRP, as well as to third-party customers in domestic and international markets.
