An electrical engineer from Punjab Mandi Board has developed
a concept of a micro hybrid power producing unit, which is an amalgamation of
biomass, biogas and solar power.
Bulwant Singh Brar, who has conceived the micro hybrid power
plant of 250 kilowatt generating capacity, said tonnes of garbage, agricultural
waste, cow dung and solar energy could be utilised as fuel to generate clean
power and provide additional source of income to the small and marginal
farmers. "Fuel is in abundance in north India," said Brar.
Addressing reporters on Wednesday, Brar, giving example of
Punjab, explained that currently all major power generation projects in Punjab
were thermal-based run on coal supplied from far-off coal fields and mines. There
were a series of power plants coming up in the state which faced fuel shortage
and were not cost-efficient. Disposal of fly ash from these plants was also a
challenge, said Brar. He said that an area of 2 to 2.5 acres, an investment of Rs.
3.5 crore and a manpower of 20-25 people was required to operate the plant and
the per unit cost of electricity would be Rs. 4.29.
The construction time for the micro hybrid plant is six
months as compared to a few years on constructing the conventional thermal
plants. "For 27 tonnes of cow dung (biogas), 2,700 to 3,000 cattle heads
are needed, which are available in one village. This would enable each village
to own and run its own power plant. The additional units could even be sold
off," said Brar.
