English
This paper reports on-site performance testing of an Archimedes screw turbine installed in a branch canal of Sardar Sarovar Narmada Nigam Limited in India. The turbine achieved 86.6% efficiency at a rated output of 410 kW, demonstrating the technical and economic viability of low-head and ultra-low-head hydropower. Such sites could contribute 45 GW per year of capacity addition for net zero by 2050, according to the International Hydropower Association.

日本のGX文脈において
日本では、既存の農業用水路や上下水道施設を活用した小水力発電が注目されており、本ケーススタディは低水頭・超低水頭サイトの開発可能性を示す参考事例となる。再生可能エネルギーの地産地消や地域分散型電源の導入促進に資する知見を提供する。
In the global GX context
Globally, low-head hydropower is an underutilized renewable energy source. This case study provides empirical evidence on the performance of Archimedes screw turbines, which can inform project developers and policymakers seeking to expand small-scale hydropower in irrigation canals and other low-head sites, contributing to renewable energy targets and energy transition.

📄 Abstract（原文）
Abstract A low head hydro project refers to hydropower sites operating at head less than 40 m and an ultra-low head refers hydropower sites operating at head less than 3 m or water flow greater than 0.5 m/s with a zero head. These hydro sites though ubiquitous, were not developed at the same pace as medium and high head sites. These sites can play a crucial role in the capacity addition of 45 GW per year for net zero by 2050 according to the International Hydropower Association report. With the introduction of Archimedes screw technology, these sites can be developed both technologically and economically. This paper presents a case study on first of its kind performance testing of electro-mechanical equipment at Archimedes screw projects located in the Vadodara Branch Canal of Sardar Sarovar Narmada Nigam Limited Gujarat. The performance testing was conducted on 4.3 m diameter Archimedes screw designed for a rated head of 6.5 m, and a rated discharge of 7.45 m 3 /s. The project is designed to deliver 410 kW turbine output, with an inclination angle of 26 degrees from horizontal. The onsite performance study carried out indicates that the achieved Archimedes screw efficiency is 86.6 %.
