Shanghai aluminum prices rose on Friday, hovering near a 11-year high, on supply worries in China amid a fresh round of electricity restrictions in major producing province of Yunnan.

The most-traded September aluminum contract on the Shanghai Futures Exchange rose 1.6% to 19,890 yuan ($3,078.33) a tonne by 0542 GMT, heading towards a January 2010-high of 20,530 per tonne.

Three-month aluminum on the London Metal Exchange fell 0.3% to $2,583 a tonne pressured by a firmer dollar, but the contract was still set for its sixth straight monthly gain.

“(Prices are rising) because of Yunnan’s electricity control,” said a China-based trader.

Aluminum producers in Yunnan province received a notice from local authorities on July 27 to restrict their power consumption, with aluminum smelter Yunnan Shenho – a unit of China’s Henan Shenhuo Coal & Power Co Ltd – set to miss its 2021 output target due to the power cut.
