普遍获得电力是撒哈拉以南非洲发展道路的一个重要部分。随着联合国将其可持续发展目标的目标7设定为普遍获得清洁、可靠和负担得起的电力,已做出大量研究努力,根据撒哈拉以南非洲国家的预测需求优化电力供应。我们的研究回顾了有关电力需求的文献,特别关注SSA的潜在需求(即,如果满足必要的技术经济条件,将存在的电力需求)。我们发现,在57份电力需求文件中,只有3份(5%)在其电力需求预测中纳入了潜在需求。此外,大多数关于撒哈拉以南非洲电力消费和需求估计的文献使用计量经济模型来确定电力消费的决定因素和预测未来需求。我们发现,人口密度,城市化,家庭收入,电价,农作物的市场价值和自然资源的可用性是显着的决定因素,在SSA的电力消费。最后,我们提出了一种方法,并提供了一个初步的概念证明,更准确地预测在撒哈拉以南非洲的潜在需求的审查。在电气化模型中分析潜在需求将有助于让能源部门的利益相关者(例如投资者和政策制定者)了解哪些部门和地理位置具有通过电力获取创造财富的潜力。
Universal access to electricity is an essential part of sub-Saharan Africa's path to development. With the United Nations setting Goal 7 of its sustainable development goals to be universal access to clean, reliable and affordable electricity, substantial research efforts have been made to optimize electricity supply based on projected demand in sub-Saharan African (SSA) countries. Our study reviews the literature on electricity demand, with a specific focus on latent demand (ie, electricity demand that would exist if the necessary techno-economic conditions were met) in SSA. We found that out of 57 electricity demand papers reviewed, only 3 (5%) incorporated latent demand in their electricity demand projections. Furthermore, majority of the literature on electricity consumption and demand estimation in SSA use econometric models to identify determinants of electricity consumption and project future demand. We find that population density, urbanization, household income, electricity price, market value of crops and availability of natural resources to be significant determinants of electricity consumption in SSA. We conclude the review by proposing a methodology, and providing an initial proof of concept, for more accurately projecting latent demand in sub-Saharan Africa. Incorporating latent demand in electrification models would help inform energy sector stakeholders (eg, investors and policymakers) about which sectors and geographic locations hold potential for wealth creation via electricity access.
