ISO proposal for a new field of technical activity „Small hydropower plants“

ISO Central Secretariat received a proposal from Standardization Administration of China - SAC for the creation of an ISO Technical Committee in the area of Small hydropower plants (SHP plants).

Scope: Standardization in the field of site selection planning, design (i.e. pre-feasibility study and feasibility study), construction and management for SHP plants development up to 30 MW.

Purpose and justification for the proposal
Small hydropower (SHP) is well recognized as an important renewable energy solution to the challenge 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, the potential of SHP in many developing countries remains untapped and is hindered by a number of factors including the lack of best practices or standards for SHP development.

According to the World Small Hydropower Development Report 2019 produced by UNIDO, the global installed SHP capacity for plants up to 10MW is around 78GW while that of the potential totals 220 GW.

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 the development 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 will alter the runoff regime. The discharge of ecological flow is particularly important to maintain river ecology, and the SHP standards should be clearly stipulated.

Proposed initial programme of work
The proposed TC aims to establish widely applicable standards for terms and definitions, design (i.e. pre-feasibility study and feasibility study), construction and management of SHP plants, excluding hydraulic turbine and associated equipment and other electromechanical equipment for SHP plants covered by IEC/TC 4, IEC/TC 14, IEC/TC 17, IEC/TC 22, IEC/TC 57. This new TC will not overlap with the existing work of ISO and IEC.

Potentional stakeholders
Industry, government, customers, suppliers, contractors, consumers, academic institutions, testing evaluation agencies and trade associations.

In case of national interest, Bulgaria can support the creation of this ISO/TC „Deoxidizers and desiccants”. If the establishment of ISO/TC is accepted by the national standards bodies – members of ISO, BDS can obtain P- or O-membership in the work of the newly established committee.

The national stakeholders can provide their position on the proposal for this new field of ISO technical activity by 05.07.2021 to Rozalina Haladzhova: rozalina.haladzhova@bds-bg.org, tel: +359 2 81 74 569.
