Regulierung, Effizienz und das Anreizdilemma bei Investitionen in intelligente Netze

Abstract

ZusammenfassungIn diesem Artikel untersuchen wir aus theoretischer Sicht, inwiefern kosten-und anreizbasierte Regulierungsregime Investitionen incentivieren. Außerdem werden diese Regulierungsregime im Hinblick auf unterschiedliche Effizienzziele (allokative, produktive und dynamische Effizienz) betrachtet. Schließlich beleuchten wir, inwiefern vor dem Hintergrund Smart Grids Netzinnovationen durch ein bestimmtes Regulierungsregime stimuliert werden können und ob hierdurch auch dynamische Effizienzziele erreicht werden.Schlüsselwörter Investitionen · Regulierung · Smart Grids · Dynamische Effizienz Regulation, efficiency and the incentive dilemma with investments in intelligent networksAbstract In this paper, we survey from a theoretical point of view to what extend cost-based and incentive-based regDieser Artikel gibt wesentliche Erkenntnisse des Diskussionsbeitrages "Regulierung und Investitionsanreize in der ökonomischen Theorie" wider, den die Autoren im Rahmen des vom BMWi geförderten Forschungsprojektes ,Innovative Regulierung für Intelligente Netze' (IRIN) erstellt haben (vgl.

For the purpose of this analysis, we furthermore differentiate by different efficiency measures, i.e. allocative efficiency, productive efficiency and dynamic efficiency and analyse to what extend each efficiency measure is stimulated by the regulatory regime. Eventually, we analyse to what extend regulatory incentives for network innovation in a smart grid context exist and to what extend different forms of regulation stimulate dynamic efficiency.

Carbon Lock-Out: Advancing Renewable Energy Policy in Europe

“…For example, traditional regulation of investment often does not account appropriately for the risk due to new technologies. Hence, new approaches aim to advance the regulatory framework to promote sufficiently large investments and set the right incentives to innovate and to apply new technologies [138,139]. This may include adding elements to the existing incentive regulation such as an investment or innovation bonus or granting higher returns to account for the risk of less well established technologies.…”

“…A basic precondition for implementing this kind of regulation is that all grid operators have a similar efficiency level. Hence, yardstick regulation follows often a foregone period of revenue/price cap regulation (Müller et al (2011)). Furthermore, the grid operators should be comparable considering cost influencing parameters.…”

“…The question of what incentives for innovation are provided by different regulation systems is discussed in several papers (see, for example, Smith (1974), Magat (1976), Cabral and Riordan (1989) and Clemenz (1991)). In accordance to Müller et al (2011) it is distinguished between investments through replacement and those for expansion. Independent of this distinction, the corresponding costs are classified as capital expenditures (CAPEX).…”

“…Bauknecht (2011) and Müller et al (2011) conclude that most studies on regulation and innovation focus on the telecommunication sector or are not related to any specific sector. One reason why there are rarely studies of the relationship between regulation and innovation in the electricity grid could be the below-average innovative character of the electricity network in the past (see, for example, ETP SG (2010)).…”

“…Meeus and Saguan (2011) found, that even if grid operators innovate, they are confronted with disincentives on the customer side with respect to participation. Müller et al (2011) argue that incentive regulation encourages innovation in the short-term, since process innovation can lead to a reduction of OPEX. This cost reduction results in higher profits for the grid operator within the regulation period.…”
