Copper producer, Sterlite Industries India Ltd on Monday said the full commissioning of its aluminium smelter at Korba Operations was affected due to recent extreme weather conditions in Korba last week.

The full commissioning of the new 250,000 tpa aluminium smelter at its subsidiary, Bharat Aluminium Company Ltd Korba Operations (Korha II) was affected due to recent extreme weather conditions, the company informed the Bombay Stock Exchange.

Because of stormy weather, the captive power plants tripped, resulting in a blackout and less than optimal supply of electricity to the Korba II potline from standby sources, it added.

Some pots were taken out from the existing production line. The remaining pots in production currently yield an output of 350 tonnes per day as compared to an average of 450 tonnes per day in the month of March.

The stabilisation of pots taken out from the potline would be completed by the end of the second quarter of 2007.

The surplus power that is generated by the company's captive power plants due to this situation would be exported to the State grid until fully used for internal requirements.
