6.3 Energy
The total energy consumption by the Group's activity sectors in 2014
was 31,834.7 Tj. This quantity was obtained from non-renewable
sources and was decreased compared to 2013, mainly as a result of
the reduced operation of the power plants of PROTERGIA, on the back
of the overall moderate demand for energy in Greece, coupled with the
increase in the installed capacity of RES plants (Photovoltaics) and with
regulatory changes in the wholesale electricity market.

The year 2014 is set as the new base
year for energy indicators, because of the
change in the calculation of total energy
consumption, in accordance with the
GRI-G4 guidelines.

by activity sector
In the Metallurgy & Mining Sector, no significant changes occurred in the consumption of energy compared to 2013.
In the EPC Projects Sector, the consumption of energy increased by 10 Tj compared to 2013, due to the launch of the construction of the company's
new projects in Algeria and of the project for the construction of the Kiato-Rododafni Railway line.

High-Efficiency Combined Heat and Power Plant
MYTILINEOS Group led developments in the efficient management of energy, by investing in the
establishment of a High-Efficiency Combined Heat and Power (CHP) Plant which uses natural gas as
combustion fuel. This investment allowed the supply to the Metallurgy & Mining sector of the quantity
of steam required to produce alumina, leading to a reduction in the consumption of fuel oil by 150,000
tons, corresponding to approximately 6 million Gj annually. The investment is also making a significant
contribution to the efforts to reduce carbon dioxide emissions at the national level, as the electricity
supplied to the National Grid substitutes the power which under the previous conditions would be
obtained from lignite combustion.
Actions to promote efficient energy consumption at the Volos plant
METKA S.A. carries out regular actions to improve energy consumption, which aim to ensure the oper-
ational efficiency of the equipment in its Volos plant. Through these actions, during the period from 2014
to 2014 the company managed to
reduce energy consumption by 24%
(from 15.85 Tj in 2004 to 12.05 Tj
in 2014).
The key actions to reduce energy consumption were the following:
Installation of 1 MW photovoltaic panels on the plant's roof.
Changes in the methods used to heat the production areas. Replacement of electrical heating units
with natural gas heat reflector panels.
Replacement of an outdated technology 100 kW air compressor with a 90 kW inverter-type
compressor.
Replacement of incandescent light bulbs with economy ones, e.g. in the plant's perimeter lighting,
in offices etc.
Annual maintenance of air conditioning units.
Annual thermographic inspection of electrical distribution panels.
Where maintenance of components or inspection of equipment is required, this is done using local
service providers.
