distribuited generation
Distributed generation allows to exploit energy resources locally. Through the implementation of “SMART GRID concept” it is possible to produce and consume energy locally in the user’s proximity (km 0). User and producer are then coincident depending on the availability of sources and energy flows.
District heating – District cogeneration

ELECTRICAL EFFICIENCY:
big power plant vs little/medium size power plant
TODAY – BIG POWER PLANTS
Big power plant (200 – 900 MWe) High electrical efficiency (45 – 54 %)
TODAY – Little and Medium power plants
Little/medium power plant (50 kWe – 10 MWe) Electrical efficiency (8 – 35 %)
ELECTRICAL EFFICIENCY:
COMBUSTION – multifuel – 50 kWe – 10 Mwe: 6 – 18% efficiency
PIROGASSIFICATION – high quality biomass chips @ 10%humiidity – 200 kWe – 10 MWe size – 35% efficiency
targets
USE OF LOW QUALITY FUEL available @ km 0 – LOW QUALITY BIOMASS and WASTE
GENERATION with MACHINE WITH HIGH ELECTRICAL EFFICIENCY also for LITTLE SIZE power plant
Little and medium size power plant
