During 2012 the company contin-
ued its systematic efforts for energy
conservation, through initiatives
which include the reengineering of
processes, the introduction of au-
tomations and the refurbishment of
equipment in its production depart-
ments. The implementation of these
initiatives resulted in 1.22 TJ of en-
ergy savings in total, up by approx-
imately 336% from last year.
The operation of the company’s
Gas - fired Combined Cycle Thermal
power plants is based on Best Avail-
able Techniques (BATs). The com-
pany’s goal is to achieve the maxi-
mum possible efficiency and
availability rates for its power pro-
duction plants and to maintain
these throughout the year.
The company’s initiatives for en-
ergy conservation (work quality
checks, daily and weekly checks of
alumina quality, mobilisation-sen-
sitisation of the personnel in-
volved, optimisation of parame-
ters, swift identification of
problem-prone basins, improve-
ments in equipment and meth-
ods), resulted in a specific con-
sumption of 13,255kWh/t – one of
the best among all aluminium
plants.
