Abstract

In the second year after the shutdown of seven nuclear power plants in March 2011, the situation of the German high voltage electricity transmission grid remained robust. Even though some expansion projects are behind schedule, the grid reconstruction advances steadily as several essential lines have made considerable progress during the last year - inter alia connections between the old and new federal states. Due to the effectiveness of existing congestion management measures, the current delay in the realization of some projects causes no concern. Measures of congestion management only comprise a very small share of the actual electricity demand; moreover, they could be carried out in a much more cost-effective fashion by coordinating them appropriately. The current methodology for the long-run grid expansion planning tends to overestimate the expansion needs - especially for two of the high voltage direct current lines ("electricity highways") that are included in the Law on National Electricity Grid Expansion Requirements ("Bundesbedarfsplangesetz"). Auch im zweiten Jahr nach dem Kernkraftwerksmoratorium vom März 2011 bleibt die Lage im deutschen Stromübertragungsnetz stabil. Auch wenn die Realisierung einiger Ausbauprojekte um einige Jahre hinter dem ursprünglichen Zeitplan liegt, schreitet der Netzumbau kontinuierlich voran. Bei einigen kritischen Leitungen wurden im vergangenen Jahr erhebliche Fortschritte gemacht, unter anderem bei Verbindungen zwischen den neuen und den alten Bundesländern. Die aktuellen Verzögerungen stellen angesichts der bestehenden Eingriffsmöglichkeiten der Netzbetreiber zur Systemstabilisierung keinen Grund zur Besorgnis dar. Maßnahmen zur Kontrolle von Netzengpässen betreffen nur einen sehr geringen Teil des Stromverbrauchs. Zudem könnten sie durch eine bessere Koordinierung zwischen den vier Netzbetreibern deutlich kostengünstiger gestaltet werden. Die Methodik der langfristigen Netzausbauplanung führt tendenziell zu einer Überschätzung des Ausbaubedarfs. Dies gilt insbesondere für zwei der im Bundesbedarfsplangesetz vorgesehenen Höchstspannungsgleichstromübertragungsleitungen (Strom-Autobahnen).
