Europäische Preisregulierungssysteme in der Wasserwirtschaft: Konzepte und Umsetzungsprobleme

Listed author(s):
  • Georg Meran

In the course of the deregulation of the telecommunication and energy sector new price regulation mechanisms were introduced to cap the access price to the respective transportation grid. While products and services are supplied under competitive market conditions the transportation girds remains under price control due to its natural monopoly property. This leads to the issue what kind of proce regulation should be implemented. In the water sector conditions are a bit different due to the limited possibility to mix water of different suppliers in one grid. Hence, the water sector remains a topography of regional monopolists which leads to the question how the tariff systems should be regulated to prevent the monopolistic exploitation of customers. This contribution gives an overview what kind of regulation systems are conceivable and which of them have been adopted in European countries. It turns out, that almost all regulation mechanisms have been properly modified to be implementable. The question remains, whether the German water sector should change its current water price regulation system. Im Zuge der Deregulierung des Telekommunikations- und Energiesektors hat in Deutschland eine neue Art an Preisregulierung des Netzbereichs Einzug gehalten. Während das eigentliche Produkt beziehungsweise die eigentliche Serviceleistung in einem deregulierten Markt unter Wettbewerb angeboten wird, ist das Transportnetz als natürliches Monopol weiterhin preisreguliert. Bleibt nur die Frage, welches Preisregulierungssystem zur Anwendung gelangen soll. In der Wasserwirtschaft verhält es sich etwas anders. Die Möglichkeiten der vertikalen Desintegrierung in Produktanbieter und Netzbetreiber ist in technischer Hinsicht nur sehr schwer zu bewerkstelligen. Die Wasserwirtschaft stellt sich vielmehr als eine Landkarte regionaler Monopole dar, und es bleibt die Frage zu beantworten, wie der Wassertarif zu gestalten ist. Es lohnt sich daher, einen Blick auf die verschiedenen Preisregulierungssysteme im europäischen Ausland zu werfen. Dieser Vergleich erfolgt hier in einem theoriegeleiteten Rahmen, um gemeinsame oder unterscheidende Elemente herauszuarbeiten und die Möglichkeiten einer Übertragbarkeit auf den deutschen Wassersektor zu erörtern.
