Hirakud
The Hirakud smelter and power complex is located in the state of Orissa, in eastern India, on the bank of the world’s longest earthen dam – the Hirakud Dam, which is 25.8-km long and spans the Mahanadi river. It is situated 6 km away from NH-6 connecting Kolkata and Mumbai and 12 km from the nearest town of Samabalpur. It is 320 km by road from Bhubaneswar, the capital of the state of Orissa.

The Hirakud smelter, set up by Indal in 1959, was the country’s second aluminium smelter operating on grid power sourced from the hydro power station of the Hirakud Dam. After facing severe power scarcity, Hirakud’s captive coal-based power plant came up in 1993. It was the first in India to adopt clean coal combustion technology that uses a circulating fluidised bed, which is considered environmentally friendly.

Today, as a part of Hindalco, the original 10,000 tpa smelter has moved to 161,400 tpa capacity with ongoing plans for further capacity augmentation to 213,000 tpa. The old HSS smelter technology has given way to the modern, environment friendly prebake smelter technology. It is the first smelter in India to have achieved this technological upgrade using the same infrastructure facilities. Similarly the power plant has been enhanced with three additional units to bring generating capacity up to 368 MW.

Further access to captive coal blocks at Talabira, approximately 45 km from Hirakud, ensures optimal backward integration for cost-competitive power to feed the aluminium smelter. Hirakud has an enviable array of international and national awards for energy conservation, safety and environment management.

As an active community player it focuses its CSR initiatives towards health care, education, women’s empowerment and sustainable livelihood programmes. The unit employs around 1,700 people.
