Power cuts take sheen off aluminum producers

Aluminum prices are on the rise as the government moves to reduce overcapacity in the sector and conserve energy in the midst of several cold spells hitting China this year.

With a quarter of the nation's aluminum production coming from Henan province, output slowed after December's bout of cold weather created electricity shortages.

By order of the government, producers were forced to reduce capacity to save electricity desperately needed to heat homes.
