Smart meters are often understood as central devices in the smart, flexible and sustainable electric grid, enabling consumers to adapt their electricity use to current supply. In this study we are interested in how different actors in a Swedish context understand the smart meters and fit them into their locally situated practices and contexts, and we analyze the smart meters with the concept of boundary objects as an analytical lens with the purpose of describing and explaining tensions between actors in intended and actual use of smart meters. The case study builds on empirical material from policy documents, web pages and user forums, and include the Swedish government, authorities, grid operators and electricity suppliers as well as consumers. The main conclusions are that consumers were not included in the design and roll-out of the smart meters, resulting in that the available information requires consumers to be active and resourceful experts.
