Case Study: Husk Power Systems

Rural electrification in India is in an acute crisis as a total of 125,000 Indian villages are presently un-electrified leaving over 480 million citizens (45% of the population) without access to reliable power, even though they spend $4.86 billion on their energy needs. The Indian government has designated 18,000 of these villages as economically impossible to reach via conventional means. Without electricity, these villagers are forced to use kerosene lanterns and diesel generators which are costly, polluting, unhealthy and dangerous. This lack of reliable power leaves them without the communication, education, and healthcare infrastructure required in modern life.
HPS designs, owns, and operates 35-100kW "mini power-plants" that use rice husk as fuel to generate electricity for villages of 400-500 households in the Indian "Rice Belt". Installation costs are less than $825/kW as compared to over $1,500/kW for solar energy. Customers save 50% (equals $60 per household per year) by switching from kerosene lantern to CFLs. HPS also receives revenue from two environmental initiatives: rice husk char collection, refinement, and sales of carbon offsets via carbon brokers.

As of 2012, Husk Power Systems has 57 plants in operation, serving 250 villages and hamlets and impacting over 150,000 peoples lives. 90 tons of CO2 saved yearly per plant. Learn more...
