Studies show the role of various electrification technologies in providing electricity access to households in Sub-Saharan Africa, with a focus on electricity demand for end-use services such as lighting, cooking, heating, cooling and other appliance use. The demand for productive use of electricity, which is important to enhance income generation opportunities and labour productivity, is usually not considered. Using the IMAGE-TIMER integrated assessment model framework, we present a methodology to project the impact of productive activities on the electricity system of the region. We show that growing productive activities increase household electricity demand by half, which has important consequences for determining the cost-optimal electrification technologies. We argue that planning of electricity systems should accommodate this increase in electricity demand for productive uses. In addition, while productive uses of electricity have a positive impact on the financial viability of electrification systems, they also increase the electricity sector investment requirements considerably.
研究表明了各种电气化技术在为撒哈拉以南非洲家庭提供电力供应方面所起的作用，重点关注照明、烹饪、取暖、制冷及其他电器使用等终端用途服务的电力需求。对电力生产性用途的需求通常未被考虑，而这种需求对于增加创收机会和提高劳动生产率很重要。我们利用IMAGE-TIMER综合评估模型框架，提出一种方法来预测生产性活动对该地区电力系统的影响。我们发现，不断增长的生产性活动使家庭电力需求增加了一半，这对于确定成本最优的电气化技术具有重要影响。我们认为，电力系统规划应适应生产性用途电力需求的这种增长。此外，虽然电力的生产性用途对电气化系统的财务可行性有积极影响，但它们也大幅增加了电力部门的投资需求。
