Despite increasing attention to the complex geographies of energy supply and use in Southern cities, energy research is still largely focusing on energy transitions evolving either through homogeneous, networked electricity or heterogeneous constellations in poor neighborhoods. Central to this research are analytical concepts used to explain energy transitions in Northern cities, such as the notion of socio-technical regimes. In this paper, we argue for a better recognition of the realities of cities in the Global South, including their diverse urban development patterns. Bringing together debates on heterogeneous urban infrastructures and energy transitions, we propose a novel analytical framework that systematically captures urban and infrastructural heterogeneity to better understand energy systems and their transitions in growing Southern cities.

Drawing on a case study on Dar es Salaam, Tanzania, we develop a spatial typology of electricity constellations using three analytical dimensions: delivery channels, the neighborhood scale, and the urban scale. Based on in-depth studies of six distinct local development types, we reveal spatially heterogeneous electricity constellations and their interplay within the city. We argue that debates on urban energy transitions in academia and policy practice need to more systematically address the diverse urban development patterns within Southern cities, their co-evolution with place-based electricity constellations and their context-specific challenges and opportunities.

尽管越来越多地关注南方城市中能源供应和使用的复杂地域，但是能源研究仍主要集中在通过贫困社区中均质的，联网的电力或异构星座演变而来的能源过渡。这项研究的核心是用于解释北方城市能源转换的分析概念，例如社会技术制度的概念。在本文中，我们主张更好地认识全球南方城市的现实状况，包括其多样化的城市发展模式。汇集有关异构城市基础设施和能源过渡的辩论，

基于坦桑尼亚达累斯萨拉姆的案例研究，我们使用三个分析维度来开发电力星座的空间类型：传递渠道，邻里规模和城市规模。在对六种不同的地方发展类型进行深入研究的基础上，我们揭示了空间异质的电力星座及其在城市中的相互作用。我们认为，在学术界和政策实践中有关城市能源转换的辩论需要更系统地解决南方城市内部的多样化城市发展模式，它们与基于位置的电力星座的共同演变以及针对具体环境的挑战和机遇。
