Practical Action has been actively developing Pico Hydro technology in Sri Lanka since 2007 as part of its Enhancing Renewable Energy Options (EREO) project. Pico hydro is potentially the lowest cost technology for off-grid electrification, producing energy from the smallest of water flows. The main environmental benefit of pico hydro is a reduction in greenhouse gas emissions and local pollution from burning fuels such as kerosene for lighting, diesel for driving machinery, and generating electricity. To date, Practical Action has successfully implemented 19 pico hydro units around the country serving rural communities with no access to the national grid. Since 2010 Practical Action has been providing technical assistance on Energy and Development initiatives to the Orissa Tribal Empowerment and Livelihoods Programme (OTELP) in the State of Orissa, India. Through this partnership, Practical Action OTELP work to eradicate poverty by incorporating energy equity into existing and future development plans focused on marginalized tribal communities in Orissa. Approximately 19,000 men and women in selected tribal areas of Orissa benefitted from pico hydro installations carried out by OTLEP in 2012.
