It is reported that India's National Aluminium Company Limited (NALCO) has reduced up to 8% capacity last year.

It is analyzed that aluminum needs burning coal to generate tremendous electricity to produce and the high raw material cost of buring coal have pushed NALCO to close down 3%~4% output.

It is said that imports and E-auction have been quite high in cost.

According to top official of NALCO, the company would carry on production to the extent of coal available from state run miner Coal India Ltd. and avoid using imported or e-auctioned coal.
