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

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)

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

Biomass is a very efficient and environmental friendly method
of power production
Biomass technology has reached a mature level (high capacity
factors)
Cogeneration can increase significantly the efficiency of the
plantConstant power production improve grids stability
A biomass system (plant + supply chain) requires a large
