Reliable and affordable access to electricity has become one of the basic needs for humans and is, as such, at the top of the development agenda. It contributes to socio-economic development by transforming the whole spectrum of people's lives-food, education, healthcare. It spurs new economic opportunities, thus improving livelihoods. Using a comprehensive dataset of pseudonymized mobile phone records, we analyse the impact of electrification on attractiveness for rural areas in Senegal. We extract communication and mobility flows from call detail records and show that electrification is positively and specifically correlated with centrality measures within the communication network and with the volume of incoming visitors. This increased influence is however circumscribed to a limited spatial extent, creating a complex competition with nearby areas. Nevertheless, we found that the volume of visitors between any two sites could be well predicted from the level of electrification at the destination and the living standard at the origin. In view of these results, we discuss how to obtain the best outcomes from a rural electrification planning strategy. We determine that electrifying clusters of rural sites is a better solution than centralizing electricity supplies to maximize the development of specifically targeted sites.
可靠且价格合理的电力供应已成为人类的基本需求之一，因此位列发展议程之首。它通过改变人们生活的方方面面——食品、教育、医疗保健，为社会经济发展做出贡献。它激发新的经济机会，从而改善生计。利用一个经过匿名处理的手机记录综合数据集，我们分析了电气化对塞内加尔农村地区吸引力的影响。我们从通话记录中提取通信和流动数据，并表明电气化与通信网络中的中心性指标以及来访游客数量呈正相关且具有特定相关性。然而，这种影响力的增加仅限于有限的空间范围，与附近地区形成了复杂的竞争。尽管如此，我们发现任意两个地点之间的游客数量可以根据目的地的电气化水平和出发地的生活水平得到很好的预测。鉴于这些结果，我们讨论了如何从农村电气化规划战略中获得最佳成果。我们确定，对农村地区的集群进行电气化改造比集中供电以最大限度地发展特定目标地点是更好的解决方案。
