Technical Guidelines for the Development of Small Hydropower PlantsDesign

Part 9: Project Cost estimates

sHP/Tg 002-09:2019

ACKNOWLEDGEMENTS

The technical guidelines (TGs) are the result of a collaborative effort between the United Nations Industrial Development

Organization (UNIDO) and the International Network on Small Hydro Power (INSHP). About 80 international experts and 40

international agencies were involved in the document’s preparation and peer review, and they provided concrete comments

and suggestions to make the TGs professional and applicable.

UNIDO and the INSHP highly appreciate the contributions provided during the development of these guidelines and in

particular those delivered by the following international organizations:

- The Common Market for Eastern and Southern Africa(COMESA)

- The Global Network of Regional Sustainable Energy Centres (GN-SEC), particularly the ECOWAS Centre for Renewable

Energy and Energy Efficiency (ECREEE), the East African Centre for Renewable Energy and Energy Efficiency (EACREEE),

the Pacific Centre for Renewable Energy and Energy Efficiency (PCREEE) and the Caribbean Centre for Renewable Energy

and Energy Efficiency (CCREEE).

The Chinese government has facilitated the finalization of these guidelines and was of great importance to its completion.

The development of these guidelines benefited greatly from the valuable inputs, review and constructive comments as well as

contributions received from Mr. Adnan Ahmed Shawky Atwa, Mr. Adoyi John Ochigbo, Mr. Arun Kumar, Mr. Atul Sarthak, Mr.
