Transparenzdefizite beim kurz- und langfristigen Engpassmanagement der Übertragungsnetzbetreiber
In the wake of the energy system transformation and the liberalisation of the electricity industry, transmission system operators (TSOs) have been given comprehensive powers and competences to ensure network and system security. These are capable of significantly affecting competition in markets that are upstream and downstream of the network. As system services increasingly have to be provided by TSOs, non-discriminatory implementation and the efficiency of the measures taken are becoming increasingly important in ensuring competition in the electricity industry. Transparency deficits that prevent a review of the measures taken by the TSOs and a discussion about possible changes in the market design should therefore be viewed critically, especially since the TSOs are regulated by the Federal Network Agency (BNetzA) and there must also be no unilateral discretion in the fulfilment of information obligations. The article shows the existing possibilities for TSOs to intervene in market developments, identifies existing transparency deficits and proposes solutions aimed at improving transparency.
