Today, the combined effect of the development of renewable energy and the electrification of the whole economy, including vehicles, is radically transforming the operation of the grid. As a result, demand-side management is increasingly attracting policy attention as a tool to increase the flexibility of electricity systems and reduce the carbon intensity of electricity supply (Parish et al. in Energy Policy 138, 2020). Specifically, demand-side management, which is active management by the user of their own demand, is expected to result in two main consumption practices (Batalla-Bejerano et al. in Energy Policy 144(C), 2020): (1) load shifting—shifting consumption from peak to off-peak periods and, (2) strategic conservation—performing activities that reduce energy consumption. In this context, smart meters, as they are implemented in households at a large scale, constitute the cornerstone of demand-side management while improving the efficiency and reliability of the overall electricity system.
