Abstract Small solar home systems (SHS) have emerged as potential alternatives to grid electrification in rural sub-Saharan Africa, enabling households to make modest investments into their power systems, and to modify those systems according to their changing incomes and power demands. In this work investigate how introduction of rural unelectrified households to basic electricity temporally stimulates increasing power demands. We use survey-gathered data to show that once households get access to basic electricity, they begin to realise its socio-economic benefits and start to desire more luxurious appliances, especially through social pressure and neighbourhood influence. These desires are realised temporally with activities that lead to increasing households' incomes, leading to increasing loads, and thus to the modifications of the originally installed small SHS, to meet those increasing load demands. Eventually, cumulative increasing loads within a given community could lead to extensions of the grid to that area, as total power demands now justify such investments. Basic SHS therefore potentially act as grid-electrification stimulators, leading to eventual grid electrification of a given community; as an electrification policy, developing communities should consider seeding unelectrified areas with SHS to stimulate power demands for eventual grid electrification.

基本电力供应如何刺激农村发展中社区家庭暂时增加的负荷需求

摘要 小型太阳能家庭系统 (SHS) 已成为撒哈拉以南非洲农村地区电网电气化的潜在替代方案，使家庭能够对其电力系统进行适度投资，并根据不断变化的收入和电力需求来修改这些系统。在这项工作中调查农村无电家庭引入基本电力如何在时间上刺激不断增长的电力需求。我们使用调查收集的数据表明，一旦家庭获得基本电力，他们就会开始意识到其社会经济效益，并开始渴望拥有更豪华的电器，尤其是通过社会压力和邻里影响。这些愿望通过导致家庭收入增加、负担增加的活动暂时实现，从而对原来安装的小型 SHS 进行修改，以满足不断增加的负载需求。最终，给定社区内累积增加的负载可能会导致电网扩展到该地区，因为现在总电力需求证明此类投资是合理的。因此，基本 SHS 可能充当电网电气化刺激器，最终导致特定社区的电网电气化；作为电气化政策，发展中社区应考虑在未电气化地区播种 SHS，以刺激最终电网电气化的电力需求。因此，基本 SHS 可能充当电网电气化刺激器，最终导致特定社区的电网电气化；作为电气化政策，发展中社区应考虑在未电气化地区播种 SHS，以刺激最终电网电气化的电力需求。因此，基本 SHS 可能充当电网电气化刺激器，最终导致特定社区的电网电气化；作为电气化政策，发展中社区应考虑在未电气化地区播种 SHS，以刺激最终电网电气化的电力需求。
