The Proposed Focus
Gasification is being recognized as an attractive
technology for Decentralized, Distributed Generation
(DDG). Large scale implementation of Distributed Power
Generation Systems of 500 kWe to 2 Mwe.
Preferably connected to tail ends of the rural, 11 KVgrids.
Small Power Packs available from 10-kWe onwards for
individual Village Electrification.

The Biomass Arguement (Logistics & Management)A distributed resourcelike biomass is best used in distributed
manner.
Large capacity plants need to cover larger areas for
feedstock.
Are more vulnerableon account of availability and price hikes.
Much smaller radius for biomass collection & transport
minimal use of dieselfor biomass transport.
Much smaller water and space requirements as compared to
other technologies.

The Rural Power Quality Arguement
11 KV grids become net producers of electricity.
This will eliminate load sheddingin rural areas,assuring round-the-clock power supply.
Power stability and qualitywill become comparable
to urban / industrial areas.
[A real dream come true!]

The T&D Losses Arguement
E&Y study on behalf of MNRE.
A minimum reduction of close to a million units oflosses per MWof installed capacity.
This direct benefit itself is equivalent to about 70 paise
(0.1 USD) per kWhr.

Environmental Aspects
Package
Water
Used in re-circulation mode with
zero discharge. Occasional ph
adjustment and simple treatmentmay be needed.
Gasifier does not release gas to
the atmosphere.Combustion in user equipments
(connected to gasifier) is much
cleaner compared to liquid fuels.
