Adequate extension of electricity transmission networks is required for integrating fluctuating renewable energy sources, such as wind power, into electricity systems. We study the performance of different regulatory approaches for network expansion in the context of realistic demand patterns...

Due to the 3rd Energy Package of 2009 the regulation of European electricity transmission did change considerably. Before, cross-border electricity issues have been regulated by voluntary contractual agreements between Transmission System Operators. Now, the new-founded Agency for the...

The purpose of this research is to evaluate the impact of vertical unbundling on German electric utilities. Our research mainly relies on in-depth interviews with sector-experts from the German utilities. We will discuss both short-term changes and the long-term impact on competition in the...

Unbundling of vertically integrated utilities has become an integral element in the regulation of network industries and has been implemented in many jurisdictions. The idea of separating the network, as the natural monopoly, from downstream retailing, which may be exposed to competition, is...

Renewable energy communities involve various agents who decide to jointly invest in renewable production units and storage. This paper examines how these communities interact with the energy system and can decrease its overall cost. First, we show that a renewable energy community can contribute...

This paper studies the pricing incentives of a monopolist constrained by a revenue cap endogenously determined by her costs in a so-called base year. Such regulation is employed, among others, to govern electricity distribution operators in Germany. We show that the revenue cap may incentivize...

This paper proposes an incentive mechanism for transmission expansion planning. The mechanism is a bilevel program. The upper level is a profit-maximizing transmission company (Transco) which expands its transmission system while endogenously predicts and influences the generation investment....

We analyze the effects of an incentive based regulatory scheme with revenue caps on the investment behaviors and decisions of 109 electricity distribution companies operating in Germany in 2006-2012. We hypothesize that Germany's implementation of incentive regulation in 2009 has a negative...

We analyze the treatment and impact of idiosyncratic or firm-specific risk in regulation. Regulatory authorities regularly ignore firm-specific characteristics, such as size or asset ages, implying different risk exposure in incentive regulation. In contrast, it is common to apply only a single...

I examine the effects of privatization, in the form of acquisitions, in the Swedish electricity distribution sector. As the majority of the distribution networks remained publicly owned, I use a synthetic control method to identify the effects on price and labor efficiency. In comparison to...
