Energy consumption & conservation
To ensure the most cost-efficient management of fuel in order to minimise consumption, the industry’s Best Available Technologies (BATs) are employed (in
this particular case, high-efficiency burners). The high-quality training of the personnel responsible for the operation and maintenance of the Company’s IPP in
Ag. Nikolaos (Viotia) has significantly helped to optimise the operation of the facility, depending on the environmental conditions that prevail each time. As a
result, primary energy savings of 97,997 GJ were made possible in 2011.
The Company’s direct energy consumption in 2011 stood at 7,769,743.2 GJ, with natural gas as the main source. The largest part of this energy was consumed
by the operation of the Company’s IPP and, to a lesser extent, for the operation of its RES plants and offices.
Total energy consumption from sources outside the Company stood at 7,679,649.6 GJ from non-renewable sources, with natural gas accounting for 99.9%
of this quantity and the rest representing electricity consumption.
Water consumption
The total quantity of water used for the Company’s activities during 2011 stood at 88,700 m
3
. Of this quantity, almost 99%was drawn from groundwater (wells)
and, more specifically, from ALUMINIUM S.A., which supplied it to the Company for the operation of its power plant. The remaining quantity, which referred to
consumption in the Company’s offices, was drawn frommunicipal water supply companies and stood at 758 m
3
, down 44% from the same consumption in 2010.
