| Summary/Abstract |
The increasing share of renewables in the electricity system results in congestion on all network levels. To address this congestion, the EU Commission proposed that distribution network operators become responsible for local congestion management. Within this paper we analyze the institutional implications of the introduction of local congestion markets (also referred to as flexibility markets) and identify three discrimination concerns related to the DSO's role on these markets. We will argue that the standard governance models (legal unbundling, ownership unbundling, IDSO) do either not sufficiently address the identified discrimination concerns, or come with additional challenges which make their application less feasible. Instead, we discuss two novel approaches: The introduction of Independent Distribution Operators (IDO) or alternatively, a Common Flexibility Platform (CFP). While the IDO results in a change of the regulatory regime in Europe, the CFP could be applied given the current European unbundling rules. Since the CFP does not require stronger unbundling of DSOs, we recommend to investigate this solution further.
