SNAPSHOT
    Husk Power Systems (HPS) generates clean, safe and efficient electricity at affordable rates in some of India’s most remote communities. HPS is currently serving 150,000 people in hundreds of villages across Bihar. Its plants extend villagers’ activities beyond daylight hours; reduce indoor air pollution; increase the time children can study; reduce the amount of time women spend collecting firewood; and reduce emissions. In the next five years HPS aims to deploy 2,000 plants, impacting five million people.
The Challenge
  • In rural India, 45 percent of households lack access to electricity. And in states like Bihar, Orissa and Uttar Pradesh – among the poorest in India – 80 to 90 percent of households are un-electrified. Villagers rely on kerosene lanterns for household light and diesel generators for irrigation and commercial power. Both are expensive and destructive to health and the environment.
The Innovation
  • HPS was founded in 2007 to target the 20,000 villages deemed out of reach by the Indian government. The company takes agricultural waste, rice husks otherwise left to rot, and converts it into gas that powers an off-the-shelf turbine to generate electricity. Each HPS plant serves two to four villages. User fees depend on the number and type of electrical appliances subscribers own.
  • The company keeps costs low by running insulated wires along bamboo poles to subscribing households, businesses and farms. It also receives a capital expenditure subsidy of up to 66 percent per system cost from the Indian Ministry of Natural and Renewable Energy.
The Impact
  • HPS currently has 75 operational plants in Bihar serving 150 villages, or more than 150,000 people. HPS extends villagers’ activities beyond daylight hours, promoting economic development and microenterprise; reduces indoor air pollution, improving health; increases the time children can study, improving education; reduces the amount of time women spend collecting firewood, increasing gender equality; and reduces emissions, protecting global and local environments.
  • Within the next five years, HPS hopes to deploy 2,000 plants across the rice belt. The result: five mllion people will have access to safe, clean and renewable power and 3,000 people in rural villages in Bihar will have jobs.
