Project's aim

The objective of this program will be to transfer knowledge from Janathakshan, to four member organizations of the Micro-Hydro Empowerment Network (HPNet)

Exchange: South-Southeast Asia Concrete Pico-Hydro Turbine Technology Transfer

The objective of this exchange is to transfer knowledge about a low-cost, easy-to-assemble pico-hydro turbine prototype, developed by the Sri Lankan organization Janathakshan, to other member organizations of the Micro-Hydro Empowerment Network (HPNet). 

The pico- hydro turbine prototype has been deployed in 45 Sri Lankan villages, of which over 85% are still functional. The turbine casing is made of concrete, while the runner is constructed from aluminum. In spite of only achieving a maximum efficiency rate of 60%, Janathakshan's model offers a number of advantages over its steel alternatives: depending on the cost of local materials, it can be up to 40% to 50% cheaper; it can be manufactured in 2 days and installed in 2 days and its construction and installation do not require a complex set of technical skills.

Green Empowerment will coordinate the exchange activity and participation of members of the Hydro Empowerment Network that will participate, i.e. Renewable Energy Association of Myanmar (REAM), Bangladesh's Renewable Energy Study Group, Yamog and AIDFI located in the Philippines, Tonibung based in Malaysia. In the Southeast Asian countries, where these organizations are located, the lack of experience, extremely high turbine costs and absence of business incentives have, to date, constrained the widespread development efforts of pico-hydro systems.  

Through the turbine knowledge exchange programme, the 5 proposing organizations aim to:

  • Conduct on-site training in turbine manufacture, assembly and installation
  • Teach controller fabrication to the participating organizations, building a foundation for controller design that can be expanded on in future
  • Collaborate in the design and installation of a pico-hydro system in a village in Sri Lanka
  • Design pico-hydro systems for suitable villages located in each of the member countries using the concrete pico-hydro turbine

Results of the exchange activity will be published on the network's webpage.
