In Q2 2013, bauxite extraction was 2.8% higher than in Q2 2012 and 6.0% higher than in Q1 2013 as a result of increased alumina production. Alumina production increased 8.5% against Q2 2012 which experienced processing issues and slightly decreased against Q1 2013.
Internal consumption of alumina amounted to 121 kilo tonne (an increase of 0.8% on Q2 2012 and 1.7% on Q1 2013) representing 29.7% of total alumina production and consistent with the aluminium smelter running at its full 250 kilo tonne per annum capacity.
Primary aluminium production in Q2 2013 was 63 kilo tonne an increase of 1.6% on Q2 2012 and 3.3% on Q1 2013.
Electricity generation in Q2 2013 increased 4.3% on Q2 2012 and decreased 17.6% on Q1 2013 reflecting seasonal demand. Supply of electricity to other Group Divisions decreased 99.4% against Q2 2012 and was in line with Q1 2013. Electricity supply to third parties increased by 174 GWh, or 511.8%, against Q2 2012 as the Group aims to maximize third party sales from the alumina refinery power plant that currently benefits from higher tariffs than the Energy Division. A 28.8% decrease in third party supply against Q1 2013 was caused by seasonal factors.
