ENERGY CONSUMPTION IN POLAND

a transportation – 150 TWh/yr,

a heat – 250 TWh/yr,

a electric energy – 140 TWh/yr, 2010

ELECTRIC POWER INSTALLED

35 GW 2010

OPPORTUNITIES FOR POWER GROWTH IN POLAND

a modernisation of coalfired plants – 1525 GW,

a nuclear power – 510 GW,

a wind power (land/off shore) – 515 GW,

a biomass

58 GW,

until yr 2030.

Biomass energy sector

] Burning of biomass for heat production.

Also cogeneration of heat and electric energy

1 mln ha of willow ] primary energy 125 TWh/yr

at growing potential 25 ton/(ha yr), energetic value 18MJ/kg

Final energy: electric 20 TWh, heat – 90 TWh

] Gasification of green plants, food / agriculture

industry waste, municipal waste, sewage.

Cogeneration of heat and electric energy

1 mln ha of corn ] primary energy 50 TWh/yr

at fermentation potential 5000 m 3 CH 4 /(ha yr), energetic value 36MJ/m 3

Final energy: electric 17 TWh, heat – 30 TWh

Fermentation potential of organic waste – over 2 mld m 3 / yr

BIOGAS STATIONS

OPPORTUNITIES

integrated systems of production of electric energy and heat,

cogeneration displaced to a location of heat demand,

biogas purified, upgraded and supplied to gas network

SMALL SCALE COGENERATION

Cogeneration cycle

for piston spark/diesel engine

Good points:

¤ High efficiency of electric energy production, also for partload conditions,

¤ Quickstartup to nominal load,

¤ Possibility of operation in places located far from transmission lines and as emergency

systems,

¤ A variety of used fuels,

¤ Relatively low investment costs.
