Form 1: Proposal for a new field of technical activity
Page 5Since the IWA33 is the result of a collaborative effort between the United Nations Industrial
Development Organization (UNIDO) and the International Network on Small Hydro Power(INSHP), both UNIDO and INSHP have confirmed full support to the constitution of this newTC in ISO (see Annex B and C). IEC/TC 4 has also indicated that it will work closely with thenew TC (see annex D).
A simple and concise statement identifying and describing relevant affected stakeholder
categories (including small and medium sized enterprises) and how they will each benefit
from or be impacted by the proposed deliverable(s).
There are two groups of beneficiaries of the proposed deliverable(s):The primary beneficiaries will be developing countries which do not have any standard to buildand operate SHP plants. The existence of internationally recognized standards for SHP plants
will lead to increased investment and benefit local businesses in and around rural areas where
SHP potential resides. Through them, the benefits will accrue to individuals and enterprises thatwill be provided with reliable energy services and renewable energy as a stimulus to ruraldevelopment and income generation activities. In the process, these communities, i.e. women,
men and children, will have improved access to energy, and linking energy services to productive
uses while achieving ISID.
The secondary beneficiaries will be manufacturers, investors of the industry who will gain
certainty when the set international SHP plants standards are available for the SHP plants
owners to follow, which will reduce piecemeal application of technical requirements anddiscrepancies among countries.
The proposed deliverable(s) is expected to reap indirect economic, social and environmental
benefits as a result.
An expression of commitment from the proposer to provide the committee secretariat if
the proposal succeeds.
China is willing to undertake the work of the new TC secretariat when the proposal isapproved.
Purpose and justification for the proposal. (The purpose and justification for the creationof a new technical committee shall be made clear and the need for standardization in thisfield shall be justified. Clause C.4.13.3 of Annex C of the ISO/IEC Directives, Part 1
contains a menu of suggestions or ideas for possible documentation to support andpurpose and justification of proposals. Proposers should consider these suggestions,but they are not limited to them, nor are they required to comply strictly with them. Whatis most important is that proposers develop and provide purpose and justification
information that is most relevant to their proposals and that makes a substantial businesscase for the market relevance and the need for their proposals. Thorough, well-developed
and robust purpose and justification documentation will lead to more informed
consideration of proposals and ultimately their possible success in the ISO IEC system.)
Small hydropower (SHP) is well recognized as an important renewable energy solution to thechallenge of increasing access to electricity in remote rural areas. However, while most countries
in Europe, North and South America, China and India have high degree of installed capacity, thepotential of SHP in many developing countries remains untapped and is hindered by a numberof factors including the lack of best practices or standards for SHP development. According toV01/2019

Form 1: Proposal for a new field of technical activity
Page 6the World Small Hydropower Development Report 2019 1 produced by UNIDO, the global
installed SHP capacity for plants up to 10MW is around 78GW while that of the potential totals
220GW.
The SHP standards will be valuable for all countries, but also allow for sharing of experienceand best practices between countries. Countries that have limited institutional and technicalcapacities will be able to enhance their knowledge base in developing SHP plants, thereby
attracting more investment in SHP projects, encouraging favourable policies and subsequently
assisting in economic development at a national level. These match UN Sustainable
Development Goals 7, and closely link to SDG 9, 5, 13 and 17.
GOAL 5: Gender Equality
GOAL 7: Affordable and Clean Energy
GOAL 9: Industry, Innovation and Infrastructure
GOAL 13: Climate Action
GOAL 17: Partnerships to achieve the Goal
The selection of the standards directly impacts the project cost, benefit and construction period
and sometimes it is even the key factor determines. Furthermore, unification of SHP standards
can remove barriers to trade, improve international market access, support public procurement,
and improve business efficiency.
The application of SHP standards can raise people's awareness of environmental protection.
The impact to the surrounding ecological environment shall be sufficiently considered during thedevelopment of SHP to ensure a scientific, reasonable and orderly development. The changes
in water resources management that occur upstream of a SHP plant during its long lifespan willalter the runoff regime. The discharge of ecological flow is particularly important to maintain river
ecology, and the SHP standards should be clearly stipulated.
In summary, the purpose for the proposal is to promote the healthy and sustainable
development of SHP globally through standardization activity.
