Development of a Sustainable Programme

• Not simply a matter of addressing the key impact areas

• Solutions must be coherent and sustainable

• Individually solutions may create their own Environmental Impact and demands

• For sustainability, individual solutions must be developed within the overall programme.

• For this reason one of the key linking elements of the EME3 programme is a comprehensive Water Management programme

• We believe that this is the first time such a co-ordinated approach has been taken to addressing Environmental Issues in Bulgaria

Renewable and Environmental Projects

Gypsum wallboard plant

• Long-term gypsum sales contract with Knauf for 50% of EME3 Gypsum

• construction of a modern gypsum wallboard factory in progress

• Positive effects:

− Environmentally friendly utilization of a waste product

− Increased local employment

− Substitution of imports

Wind and Solar Energy

• Gurkovo windfarm under development; to be operated by Enel Operations Bulgaria

• EME3 plans to install small solar plant at TPP EME3 site

• These projects will allow EME3 to balance its power generation with a share of renewable energy, in line with Bulgarian and EU targets

Renewable and Environmental Projects

MOU EME3 – Ciccolella Group

• MOU signed in Sofia on Jan. 21, 2008 to conduct a joint technical and financial feasibility study for the development of a 70 hectares flower greenhouse facility using the energy produced by the EME3 power plant for heating

• The project will have a positive impact in the area both from a social (more than 300 people to be employed) and environmental perspective (higher efficiency)

• To be implemented within the framework of Bulgarian and EU regulations on the efficient use of energy
