Middle East aluminium producers are shrugging off record-high global energy prices as they capitalise on cheap gas-generated electricity and a construction boom to boost world market share.
Power bills account for about a third of an aluminium smelter's total costs.
"The most recent expansions of the company's production facilities...have contributed to the increased output," Khalid Buhumaid, a Dubal general manager, told Reuters.
"We have also continued to see strong demand in the first quarter of 2008 and accordingly our output was 5 per cent higher compared to the same period last year (at 228,378 tonnes)."
Apart from hydrocarbons, aluminium is one of the largest industries in the Opec oil-exporting nation which groups seven emirates including regional trade and tourism centre Dubai.
Competitively priced energy and a construction boom in the world's biggest oil exporting region, where there are more than $1 trillion (Dh368 trillion) of infrastructure projects, are boosting demand.
"In 2007 22 per cent of our total sales volume was consumed in the Middle East," Buhumaid said.
"This region is currently Dubal's third largest market, after Asia and Europe."
Dubal was also expected to ship 100,000 tonnes of aluminium to Japan this year to meet demand for the material, Buhumaid said. About 52 per cent of the shipment will be billet, while high purity aluminium will account for about 25 per cent, he said.
In 2006 Dubal produced 789,341 tonnes of extrusion billets and foundry alloys, used mainly in construction, transport and electrical industries.
Alumina is the main raw material for smelting aluminium.
Dubal is expected to increase its production capacity to more than 950,000 tonnes by the end of this year.
Dubal aims to be among the world's top five aluminium producers by 2015. Its expansion plans include the construction of the world's largest green-field aluminium smelter complex, costing $8 billion (Dh29.44 billion), a joint venture with Mubadala Development Co.
The Emirates Aluminium (Emal) complex in Abu Dhabi would eventually have an output capacity of 1.5 million tonnes a year.
Russia's Rusal now operates the world's biggest aluminium smelter at Bratsk with a capacity of 976,000 tonnes per year.
Dubal’s only competitor in the Gulf Arab region, Aluminium Bahrain (Alba), which produces 830,000 tonnes of the metal a year, said last year it was mulling plans to raise its output by up to 45 per cent to about 1.2 million tonnes.
