Join an International Workshop on Technical Guidelines for the Development of Small Hydropower Plants


Workshop dates October 19-23 2020; Register by October 15

The American National Standards Institute (ANSI) invites interested stakeholders to join a virtual workshop to develop an International Organization for Standardization (ISO) International Workshop Agreement (IWA) on technical guidelines for small hydropower (SHP) plants. The Standardization Administration of China (SAC) and Austrian Standards International - Standardization and Innovation (ASI), will host the workshops in association with the International Center on Small Hydropower (ICSHP), on October 19-23, 2020. Register by October 15.

The workshop is intended to develop IWA 33-3 Technical Guidelines for the Development of Small Hydropower Plants - Part 3: Design guidelines, which aims to:

  • Provide a platform to facilitate the standardization of the general terms and definitions for SHP plant development
  • Allow for the efficient and effective design guidelines of SHP plants worldwide based on best practices gathered from a wide variety of countries

What is an IWA?

An IWA is a type of document that is developed with direct participation of stakeholders outside of the traditional ISO country representation system to enable players to negotiate in an open workshop environment. After the IWA workshop, text will be edited and published.

The effort builds upon the June 25 and 26, 2019, ISO IWA 33 Workshop on "Technical Guidelines for the Development of Small Hydropower Plants: Terms and Definitions; and Design," held in Hangzhou, China. As an outcome of the workshop, IWA 33 (Part 1) for Vocabulary and IWA 33 (Part 2) for Site selection were published on December 10, 2019,.

According to the workshop invitation, while various national SHP strategies and guidelines exist, none provide a solution to assist in the facilitation of SHP development on a global scale. Bridging this gap can be beneficial in terms of efficient electricity generation supporting in national socioeconomic development whereby assisting in poverty alleviation while promoting environmental awareness.

According to an invitation document issued by Antoine Morin, secretary of the ISO Technical Management Board (TMB), the IWA is intended for use by developed, developing, and least developed countries alike. The general terms and definitions specify the professional technical terms and definitions commonly used for small hydropower stations. The design guidelines cover small hydropower up to 30 MW and provide guidelines for basic requirements; methodology and workflow in terms of site selection, hydrology, geology, hydraulics, electromechanical equipment selection, construction, economic evaluation, and social and environmental assessment, etc.
