PPCR’s Mission & Strategy

 PPCR is a wholly-owned subsidiary of PPC S.A. and being the only vertically integrated RES

• perator in Greece, its objective is to secure a leading position in the Greek RES market by the end
• f the decade by increasing significantly its market share of the Greek RES market from 6%

currently to approximately 20%, contributing thus to the national green development vision and to the creation of the foundations for sustainable development.

 PPCR’s Strategy is founded on two central pylons:

• 1. The development of a portfolio in all RES forms, involving:



The construction of new large inland and island W/P’s involving major interconnection works



The construction of two of the largest PV stations in Europe and in the world as well as many smaller ones



The exploration of the high enthalpy geothermal fields in the Aegean islands



The construction of new Small Hydro electric stations



The development of hybrid systems



The development of Biomass



The planning of offshore wind parks

• 2. The strategic co-operations home and abroad, aiming to jointly develop RES projects and to achieve

exchange of knowhow

3

PPCR’s Strategic Levers

 PPCR’s goal is to enhance its position in the Greek market by achieving critical mass through the

development of a sizeable, diversified asset portfolio

Well diversified portfolio by type of RES and market

• Historically present in RES development in Greece
• Involved in all commercial RES technologies
• Projects with the widest geographic dispersal
• Small projects with huge local significance

Investment decision making process in line with growth expectations

• Develop a faster and more flexible corporate structure and investment decisions making process in line with PPC

procedures

Operational performance

• Optimize on operational and management performance so as to increase efficiency, margins and hence

competitiveness

• Capitalizing on its employees’ technical expertise and operational experience, PPCR has a solid base to position itself

among the most important players in the market

Extroversion via meaningful collaborations

• Co-operation Agreements with strategic content
• Co-operations for unique and large projects

Biomass (general overview) Presentation of the Project Project’s Benefits Conclusions

6

Electricity production from biomass in Europe and globally  Biomass contributes 14% of global

energy consumption (25% in industrialized countries and 75% in developing)

 Approximately 860 TWh of biomass

energy (heat & electricity) are used mainly in Europe and North America

 Only 1.3% of world production an

energy comes from biomass (estimated to be 2.4% in 2030)

 The contribution of electricity from

biomass in energy balances of individual countries varies from 0% to 10.9% (Finland)

7

Electricity production from biomass in Europe and globally

 In the EU the development of electricity from biomass burning solid forms has increased an average of 14.7% annually from 2001 to 62,2 TWh in 2009  There are about 800 biomass power plants in the EU with a total capacity of 7,1 GW  The countries with the highest concentration of power plants of solid biomass is the Nordic (Finland, Sweden) and also Germany and Austria  The corresponding investment in developing countries is based on the prevailing favorable policy for over a decade, by subsidizing biomass for electricity production

Organizing the Supply Chain

The indicative total area of ​the Region of Western Macedonia is 9,451,000 acres*. According to these estimates in order to meet the needs of the 25MW biomass power plant 1.4% of the total area (although the yields of energy crops is 1 ton / 0.1ha) or 0.7% of the total area (if the efficiency is 2 tons/ha) is required. Estimated percentage of land required for the operation of a 25 MW power plant, for various transportation ranges of the crop and various yields of energy crops

* 1 acre = 4 ha
