The purpose of this study is to analyze the cost efficiency of electricity distribution systems in order to enable regulatory authorities to establish price- or revenue cap regulation regimes. The increasing use of efficiency analysis in the last decades has raised serious concerns among...

For a long time considered as technologically mature, electric systems are now facing a period of rapid evolution, inspired by climate change concerns. Several studies show that current regulation of natural monopolies does not offer sufficient incentives for network operators (and network...

We study the impact of different regulatory and ownership regimes on the dividend policy of regulated firms. Using a panel of 106 publicly traded European electric utilities in the period 1986-2010, we link payout and smoothing decisions to the implementation of different regulatory mechanisms...

It is puzzling today to explain both the diversity and the rationale of regulators' practice vis-à-vis network monopolies. We argue that two fundamental characteristics should be considered when defining the most appropriate regulatory tools. First, it is the bounded endowment of regulators set...

Price caps (also known as RPI-X or incentive regulation) encourage regulated companies to cut costs through the profit incentive, by fixing revenues irrespective of the company's own costs for a certain period. However, eventually, cutting costs become less important than incurring costs to...

Incentive regulation needs to adapt to the emerging changes in the operating environment of the electricity networks and take into account the security of these. This paper assesses the current issues and options in economic regulation of network security across the European electricity systems....

We analyze various regulatory regimes for electricity transmission investment in the context of a transformation of the power system towards renewable energy. We study distinctive developments of the generation mix with different implications on network congestion, assuming that a shift from...

To date, the distributive implications of incentive regulation on electricity transmission networks have not been explicitly studied in the literature. More specifically, the parameters that a regulator might use to achieve distributive efficiency under price-cap regulation have not yet been...

We propose a price-cap mechanism for electricity-transmission expansion based on redefining transmission output in terms of financial transmission rights. Our mechanism applies the incentive-regulation logic of rebalancing a two-part tariff. First, we test this mechanism in a three-node network....
