Advances in automated energy metering system over the years have engendered transparency, self-control, efficiency, and equity in energy use especially among residential households globally. Despite this development, only few studies have shown the disaggregated effects of household attributes, dwelling characteristics, and metering systems on residential energy efficiency in the Global South. This paper argues that apart from household contextual factors—socio-economic and housing—the metering systems could indirectly account for energy disparities among urban households. This study therefore compared electricity consumption by urban households under the postpaid meter system and the prepaid meter system using electricity utility data obtained from residents in Ojo Lagos, Nigeria. Findings indicated that electricity consumption levels differed significantly between the postpaid and the prepaid metered households. Further analyses showed that the prepaid meter households used 47% less electricity kWh per annum compared with the postpaid meter households, intra-group variations in domestic electricity use were attributed to the household socio-economic and residential characteristics, and inter-group variations in electricity use rates were attributed to the metering system used by households. This study has both practical and policy implications for urban energy management especially with regard to the metering systems put in place for residential energy use and the need to ensure energy justice in socio-economically polarized cities.

后付费预付费计量房屋的能源效率:分析尼日利亚拉各斯的社会经济,住房和计量因素的影响

多年来,自动电能计量系统的进步带来了透明度,自我控制,效率和能源使用公平性,尤其是在全球范围内的居民家庭中。尽管取得了这种进展,但只有极少的研究显示出家庭属性,住宅特征和计量系统对全球南方住宅能源效率的分类影响。本文认为,除了家庭背景因素(社会经济和住房)之外,计量系统还可以间接解决城市家庭之间的能源差异。因此,本研究使用从尼日利亚Ojo Lagos居民获得的用电数据,比较了后付费电表系统和预付费电表系统下城市家庭的用电量。调查结果表明,后付费和预付费家庭之间的用电量水平差异很大。进一步的分析表明,与后付费电表家庭相比,预付费电表家庭每年使用的电量减少了47%,组内家庭用电量的变化归因于家庭的社会经济和居住特点,以及群体间电的变化使用率归因于家庭使用的计量系统。这项研究对城市能源管理具有实际和政策意义,特别是在为居民能源使用的计量系统以及确保社会经济两极分化的城市中确保能源公正方面。进一步的分析表明,与后付费电表家庭相比,预付费电表家庭每年使用的电量减少了47%,组内家庭用电量的变化归因于家庭的社会经济和居住特点,以及组间电的变化使用率归因于家庭使用的计量系统。这项研究对城市能源管理具有实际和政策意义,特别是在为居民能源使用的计量系统以及确保在社会经济两极分化的城市中确保能源公正性方面。进一步的分析表明,与后付费电表家庭相比,预付费电表家庭每年使用的电量减少了47%,组内家庭用电量的变化归因于家庭的社会经济和居住特点,以及组间电的变化使用率归因于家庭使用的计量系统。这项研究对城市能源管理具有实际和政策意义,特别是在为居民能源使用的计量系统以及确保社会经济两极分化的城市中确保能源公正方面。组内家庭用电量的变化归因于家庭的社会经济和居住特征,组间用电量的变化归因于家庭使用的计量系统。这项研究对城市能源管理具有实际和政策意义,特别是在为居民能源使用的计量系统以及确保社会经济两极分化的城市中确保能源公正方面。组内家庭用电量的变化归因于家庭的社会经济和居住特征,组间用电量的变化归因于家庭使用的计量系统。这项研究对城市能源管理具有实际和政策意义,特别是在为居民能源使用的计量系统以及确保社会经济两极分化的城市中确保能源公正性方面。
