This article aims to contribute to recent debates on the politics of smart grids by exploring their installation in low-income areas in Kingston (Jamaica) and Rio de Janeiro (Brazil). To date, much of this debate has focused on forms of smart city experiments, mostly in the Global North, while less attention has been given to the implementation of smart grids in cities characterised by high levels of urban insecurity and socio-spatial inequality. This article illustrates how, in both contexts, the installation of smart metering is used as a security device that embeds the promise of protecting infrastructure and revenue and navigating complex relations framed along lines of socio-economic inequalities and urban sovereignty – here linked to configurations of state and non-state (criminal) territorial control and power. By unpacking the political workings of the smart grid within changing urban security contexts, including not only the rationalities that support its use but also the forms of resistance, contestation and socio-technical failure that emerge, the article argues for the importance of examining the conjunction between urban and infrastructural governance, including the reshaping of local power relations and spatial inequalities, through globally circulating devices.

Underlying Risk

The process of urbanisation has historically been associated with both socioeconomic development and social strain. Although there is little evidence that urbanisation per se increases the likelihood of conflict or violence in a country, in recent decades Africa has experienced exceptional rates of urban population growth in a context of economic stagnation and poor governance, producing conditions conducive to social unrest and violence. In order to improve urban security in the years ahead, the underlying risk factors must be addressed, including urban poverty, inequality, and fragile political institutions. This, in turn, requires improving urban governance in the region by strengthening the capacity of local government institutions, addressing the complex political dynamics that impede effective urban planning and management, and cultivating integrated development strategies that involve cooperation between various tiers and spheres of government and civil society.
