PPCRs Mission & Strategy

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

operator in Greece, its objective is to secure a leading position in the Greek RES market by the endof 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.

PPCRs 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/Ps 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

Conclusions


6/306

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)


7/307

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
