Prosumage of solar electricity: pros, cons, and the system perspective

摘要: We examine the role of prosumage solar electricity, i.e. PV self-generation combined with distributed storage, in context low-carbon energy transformation. First, we devise a qualitative account arguments favor and against prosumage. Second, give an overview Germany. Prosumage will likely gain momentum as support payments expire for increasing share capacities after 2020. Third, model possible system effects German 2035 scenario. batteries allow notable substitution other storage facilities only if fully available market interactions. System-friendly operation would also help limiting cost increases. conclude that policymakers should not unnecessarily restrict prosumage, but consider distributional aspects.
