2. 2008 2 Location and Profile of Project Development of a Sustainable Programme Key Elements of the EME3 Programme Waste Management Emissions Reductions Effluent and Sewage Treatment Renewable and Environmental projects A Sustainable Environmental Programme Agenda

3. 2008 3 The Enel Maritza East 3 power station is situated in the south part of Central Bulgaria and is adjacent to the Town of Gulabovo and the villages of Mednikarovo. Iskritza and Obruchishte Location Enel Maritza East 3 was constructed at the end of the 1970’s and is one of the three thermal power stations in Maritza East Complex Enel Maritza East 3

4. 2008 4 EME3 is currently being rehabilitated with the objectives of increase output to approx. 900MW, improving efficiency, extending operating life by 15 years and bringing the plant into compliance with European Environmental Standards. Euro 160 million is allocated solely to the Environmental Projects required to achieve compliance Project Profile Enel Maritza East 3

5. 2008 5 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 A Sustainable Environmental Programme

6. 2008 6 Key Elements of the EME3 Programme Waste Management –Segregated and managed disposal of Hazardous and Non Hazardous materials –Recycling of paper, metal and batteries Emissions Reductions –Flue Gas Desulpherisation (FGD) –Electrostatic Precipitator (ESP) –Dust Mitigation measures for Ash Lagoons Discharges –Sewage and Effluent Treatment Plants Overall Water Management Programme. –Conservation and Recycling A Sustainable Environmental Programme

8. 2008 8 Emissions Reductions 94% of SO2 removed Uses water recycled from Plant Cooling Water System Waste product gypsum used for production of wallboard Wallboard Factory provides additional local employment A Sustainable Environmental Programme

9. 2008 9 Effluent and Sewage Treatment Plant Since August 2006 sewage which had previously been discharged directly into a local river has been treated by this plant Commissioned last year the Effluent Treatment Plant treats all waste waters produced by EME3 before discharge. A Sustainable Environmental Programme

10. 2008 10 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

11. 2008 11 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
