Engineer develops micro hybrid power plant
Using a unique blend of technologies of the non-conventional energy sector, a Punjab engineer has developed a concept and designs of a micro hybrid power plant, which could not only make a village self sufficient in its power needs but provide organic manure as well as run chilling centres or cold storages.
Talking to The Hindu, Bulwant Singh Brar, who retired from the Punjab Mandi Board said that he had the patents and trademark for the mathematical formula he had worked out to set up MHPP of 250 kilowatt through a combination of solar power, bio-gas and bio-mass technologies to produce electricity. Each plant can be set up on a 2.5 acre plot of land with an investment of approximately Rs. 3.00 crore and provide employment to about 20 persons, while the per unit cost of power generation would average around Rs. 4.29.
Following his meetings at different levels, Mr. Brar said that Department of Science and Technology of the Union government had agreed to provide up to 80 per cent of the funds required to set up pilot plants, if a relevant proposal was processed and recommended by the respective State governments, some of which have initiated the procedure to identify at least one spot in every district.
Mr. Brar said that one MHPP could come up in just six months as compared to the years spent on constructing the conventional thermal plants. A village with about 3000 cattle head could provide 27 tonnes of cow dung to produce biogas, three tonnes of farm residue like paddy husk, straw or cotton stalks as bio-mass raw material for such a plant. Coupled with the solar power that would be generated on the plants rooftop, the village could be assured of 24 hours power supply, for domestic use. The plant would daily produce around 2.7 tonnes of compost and about 15 quintals of ash, whose management or storage was a viable proposition.
