Turn IT on! - User Acceptance of Direct Load control and Load Shifting of Home Appliances

In 2030 at latest, half of the power production in Germany has to consist of renewable energy. The problem is not to produce enough renewable energy but to provide it when needed and to control it in such a way that the electricity system does not collapse. Direct load control (DLC) is seen as a great opportunity to solve the big problem of the energy turnaround. Therefore, this paper examines drivers and barriers for the acceptance towards load shifting of home appliances. Particularly the role of trust in the energy provider is under investigation. For this, we conducted a survey among 653 end consumers. Results show that on the one hand the ecological impact, the increased comfort, and the financial benefits influence the acceptance of DLC. On the other hand, the loss of control, the technical safety, and not well protected usage profiles decrease the acceptance. While trust in the provider does not impact the attitude towards DLC directly, it plays an important role for the perception of advantages and disadvantages.
