Small Hydropower Technology

 

 

 

Small hydropower is one of the most suitable renewable energy solutions for productive use and rural electrification. Small hydropower is a mature technology that can be easily constructed, operated and maintained locally.

 

A great share of the small hydropower value chain benefits local economies. It has the lowest electricity generation prices of all off-grid technologies, and has the flexibility to be adapted to various geographical and infrastructural circumstances.

 

Increased small hydropower development will showcase the use of renewable energy in industries, and small and micro enterprises. It is an ideal technology option to mainstream renewable energy use to improve productivity, boost industrialization and reduce geographic inequality in industrial production.

 

To date, much of the world’s small hydropower potential remains untapped. The first step to promote small hydropower is through dissemination of reliable data for policy development and energy planning, as well as through guiding investors in entering renewable energy markets.

  • The manifold benefits of small hydropower - the relatively low investment capital, small engineering work, simplistic maintenance and operation, minimal environmental impacts, suitability for scattered development in rural and remote areas - have attracted special attention from the global community.
  • Small hydropower has seen rapid development in many countries, making important contribution to meeting daily electricity demand, reducing poverty and advancing socio-economic improvement.
     

This training will give participants the opportunity to learn about the basics of small hydropower technology. The training is intended to give an introduction to the varied disciplines involved in planning, designing, constructing, and operating small hydropower.
Each module (or chapter) can be taken separately. The platform allows the users to navigate the training in a flexible way, with the possibility to choose the areas of interest.

 

 

The primary audience of this training is WBG energy staff with limited or no prior experience in small hydropower projects, as well as renewable energy practitioners in developing countries, in particular those that are involved in small hydropower projects (e.g. investors, economists, sociologists, lawyers, etc., or narrow specialists), that need to get a broader introductory view on how these projects are prepared and implemented.

 

 

This training is not intended to cover the topic in an exhaustive way or to handle all the complex issues related to small hydropower technology. This training contains information from a variety of resources. The World Bank Group does not control, monitor or guarantee the information contained in links to external websites or resources.
 

  • Gain a thorough understanding of the key technical and financial elements required for sound planning of small hydropower investments
  • Understand the construction process and its different elements, focusing on civil and electro mechanical works
  • Learn best practices for project implementation and for management during operation and maintenance
  • Know how to identify and mitigate negative environmental and social impacts associated to small hydropower, including cumulative impacts
  • Learn from global experiences in developing and operating small hydropower plants

 

There is no internationally accepted definition of ‘small’ hydro.

 

Small Hydro World, a multi partner initiative between the International Center on Small Hydro Power and UNIDO, defines small hydropower as having a capacity of up to 10 MW per plant (World Small Hydropower Development Report 2013, UNIDO & ICSHP).
Nevertheless ‘small’ hydro is defined differently from country to country, and the upper capacity limit generally ranges from 10 MW to 50 MW (in some cases up to 100).

 

The World Bank Group does not officially differentiate between small and large hydro according to capacity. In this training, the WBG has thus decided to not strictly define ‘small’ hydro, but use it as an administrative distinction – the principles of the technology is not different larger schemes, the challenges are.

Teaser Description (Limited to 800 characters): 

This online training will give participants the opportunity to learn about the basics of small hydropower technology.

The course is intended to give participants a solid introduction to the varied disciplines involved in planning, designing, constructing and operating small hydropower.

Topics include introduction to small hydro, planning, civil design, electro mechanical works, project construction and management, operation-maintenance-renovation, financing aspects, global experiences with small hydropower plants (e.g. lessons learnt, barriers to development and their mitigation, lessons from failures).

Each module can be taken separately. By taking all the modules, the online participant will gain a good understanding of what is involved in making a small hydropower successful.
