Abstract

This study assessed the technical and economic viability of Poldaw wind pumps for irrigates shallot cultivation in the Keta Municipality in Ghana. Technical analyses of 4 versions of the Poldaw pump is conducted to determine if it they can supply the water requirements for irrigated shallot farming. The Levelized Cost of Energy (LCOE) of wind energy for irrigation over a period of 20 years is also calculated and compared with that of grid electricity, diesel, petrol and premix fuels as alternative energy sources for irrigated shallot farming in the area. At a hub height of 10 m, the 5.0 m Poldaw was found to be capable of supplying the daily water requirements for irrigated shallot farming in the area. In addition, its LCOE is better than those of petrol, diesel and premix fuel. Grid electricity lost its slight advantage on LCOE when the Poldaw pump was assessed for hub heights of 12 m and higher. The findings of the study suggest that the 5.0 m Poldaw pump is a viable alternative to pumps powered by other energy sources currently used for irrigated shallot farming in the Municipality.

加纳部分沿海地区灌溉葱种植所用不同能源的平准化能源成本比较

本研究评估了 Poldaw 风泵在加纳 Keta 市灌溉大葱种植方面的技术和经济可行性。对 4 种型号的 Poldaw 风泵进行了技术分析，以确定它们能否满足灌溉大葱种植的用水需求。还计算了 20 年内用于灌溉的风能的平准化能源成本（LCOE），并将其与电网电力、柴油、汽油和预混燃料作为该地区灌溉大葱种植的替代能源进行了比较。在轮毂高度为 10 米的情况下，5.0 米高的 Poldaw 可以满足该地区大葱灌溉的日常用水需求。此外，其 LCOE 优于汽油、柴油和预混燃料。在对轮毂高度为 12 米及以上的 Poldaw 水泵进行评估时，电网电力在 LCOE 方面略微失去优势。研究结果表明，5.0 米的 Poldaw 泵是该市目前用于灌溉大葱种植的其他能源泵的可行替代品。
