Came across this article today by David Bornstein highlighting an innovative approach to providing power to poorer parts of the globe. This particular article is about a new company, Husk Power, set up in the state of Bihar in India.
The author does such a wonderful job in framing and highlighting the key aspects of the story that I am happy to just reproduce here selected portions of this long and well-written story:
In vast stretches of the developing world, after the sun sets, everything goes dark. In sub-Saharan Africa, about 70 percent of the population lack electricity. However, no country has more citizens living without power than India, where more than 400 million people, the vast majority of them villagers, have no electricity. The place that remains most in darkness is Bihar, India’s poorest state, which has more than 80 million people, 85 percent of whom live in households with no grid connection. Because Bihar has nowhere near the capacity to meet its current power demands, even those few with connections receive electricity sporadically and often at odd hours, like between 3:00 a.m and 6:00 a.m., when it is of little use.
This is why I’m writing today about a small but fast-growing off-grid electricity company based in Bihar called Husk Power Systems. It has created a system to turn rice husks into electricity that is reliable, eco-friendly and affordable for families that can spend only $2 a month for power. The company has 65 power units that serve a total of 30,000 households and is currently installing new systems at the rate of two to three per week.
What’s most interesting about Husk Power is how it has combined many incremental improvements that add up to something qualitatively new — with the potential for dramatic scale. The company expects to have 200 systems by the end of 2011, each serving a village or a small village cluster. Its plan is to ramp that up significantly, with the goal of having 2,014 units serving millions of clients by the end of 2014.
Husk Power was founded by four friends: Gyanesh Pandey, Manoj Sinha, Ratnesh Yadav and Charles W. Ransler, who met attending different schools in India and the United States. Pandey, the company’s chief executive, grew up in a village in Bihar without electricity.
Pandey and Yadav began bringing pieces together for an electric distribution system powered by the husks. They got a gasifier, a generator set, filtering, cleaning and cooling systems, piping and insulated wiring. They went through countless iterations to get the system working: adjusting valves and pressures, the gas-to-air ratios, the combustion temperature, the starting mechanism. In they end, they came up with a system that could burn 50 kilograms of rice husk per hour and produce 32 kilowatts of power, sufficient for about 500 village households.
They reached out to people in a village called Tamkuha, in Bihar, offering them a deal: for 80 rupees a month — roughly $1.75 — a household could get daily power for one 30-watt or two 15-watt compact fluorescent light (CFL) bulbs and unlimited cell phone charging between 5:00 p.m and 11:00 p.m. For many families, the price was less than half their monthly kerosene costs, and the light would be much brighter. It would also be less smoky, less of a fire hazard, and better for the environment. Customers could pay for more power if they needed it — for radios, TVs, ceiling fans or water pumps. But many had no appliances and lived in huts so small, one bulb was enough. The system went live on August 15, 2007, the anniversary of India’s independence.
It worked. Back in the United States, their colleagues Sinha and Ransler, who were pursuing M.B.A.s at the University of Virginia’s Darden School of Business, put together a business plan and set out to raise money. They came first in two student competitions, garnering prizes of $10,000 and $50,000. The company received a grant from the Shell Foundation and set up three more systems in 2008. It has since raised $1.75 million in investment financing. In 2009, they had 19 systems in operation; in 2010, they more than tripled that number.

For decades, countries have operated on the assumption that power from large electricity plants will eventually trickle down to villagers. In many parts of the world, this has proven to be elusive. Husk Power has identified at least 25,000 villages across Bihar and neighboring states in India’s rice belt as appropriate for its model. Ramapati Kumar, an advisor on Climate and Energy for Greenpeace India, who has studied Husk Power, explained that the company’s model could “go a long way in bringing light to 125,000 unelectrified villages in India,” while reducing “the country’s dependence on fossil fuels.”
But the lessons here go beyond the fortunes of Husk Power. What the company illustrates is a different way to think about innovation — one that is suitable for global problems that stem from poor people’s lack of access to energy, water, housing and education. In many cases, success in these challenges hinges less on big new ideas than on collections of small old ideas well integrated and executed. “What’s replicable isn’t the distribution of electricity,” says Pandey. “It’s the whole process of how to take an old technology and apply it to local constraints. How to create a system out of the materials and labor that are readily available.”
===>Developments like these go to show that there are multitude of ways to solve our energy problems and all of them have an useful role to play. Let's hope we get to report on many more developments like these all over the world in the future.
