DESI POWER
DESI Power is a collaboration between DASAG,
India and TARA (Technology for Action and Rural Advancement) which offers at
a turnkey system to supply electricity and energy services using renewable
sources of energy. DESI, is a company which promotes decentralised
Independent Rural Power Producers. It sets up independent Rural Power
Producers (IRPPS) at the unit level, as joint ventures with local
communities and private entrepreneurs. Its management and approach is
similar to that of private sector power producers in the centralised sector.
DESI Power
promotes packages, builds, operates and later transfers the plants to local
ownership. Although the objectives of DESI Power have their origins in
social, environmental and sustainable development concerns, its operations
and financial structures are designed to be commercially viable so as to
ensure scalability and long term viability. DESI power plants are based on
the gasification of locally available biomass which is available on regular
basis.
Technology
The electricity
generation process involves the following major steps:
|
● |
Biomass collection |
|
● |
Cutting and drying |
|
● |
Gas formation and
scrubbing |
|
● |
Power production |
Advantages of DESI power plants
Resource efficient
Conserve non-renewable energy resources
(diesel) to the tune of more than 75%; new plants will offer 100%
replacement of diesel.
Environment Friendly
Utilizes waste biomass to produce valuable electricity
Considerably lower emissions and less pollution if compared to coal fired
power plants
Consistent in supply
Highly reliable source
of electricity when compared to grid supply
Extremely useful for
continuous industrial production processes which otherwise hampers the
efficiency.
Cost
efficient
Even at as low plant load factor as 40% and with high raw material cost, the
cost of production per unit comes to Rs. 4.50 - Rs. 5.00, which is highly
competitive with grid electricity price. The cost of generation is even
lower with gas engines.
Encourage livelihood creation
Promotes job creation –
work within the power plant, in new local micro-enterprises and small scale
industries, which consumes the power from the gasifier plant.
Promote sustainable development
Local value addition to local resources
will accelerates the village/small town development process, reduce
migration to large cities and hence strengthen the local economy.
Business
DESI Power is building or has built more than 12 gasifier based power plants
of varied capacities ranging from 20 Kwe to 1.2 MW. These are running
efficiently in various part of the country. The two most determining
factors for cost of production include: the cost of biomass fuel and the
plant load factor achieved. It is observed that even with Plant Load Factor
(PLF) lower than 40%, with high biomass cost and lower than optimal diesel
replacement, the cost of electricity remains competitive to the cost of
electricity per unit from the grid supply.
