The European climate targets until 2050 require an adaptation of the generation portfolio in terms of renewable and fossil based generation. Assumptions on the timeline of the targets and the availability and costs of generation technologies are used in energy system models to optimize the cost...

The North and Baltic Sea Grid is one of the largest pan-European infrastructure projects raising high hopes regarding the potential of harnessing large amounts of renewable electricity, but also concerns about the implementation in largely nationally dominated regulatory regimes. The paper...

This paper investigates the impacts of the eastern enlargement of the European Union in 2004 and the liberalisation of European electricity markets on Germanys electricity exchange with neighbouring countries and on electricity prices. Thus, electricity imports from Czech Republic have increased...

This paper, which is one of the first to estimate productivity in retail electricity for a European country after liberalisation, analyses the effect of ownership and governance structure by using a unique dataset of German electricity retailers from 2003 to 2012. An innovative service...

We analyze the pass-through of cost changes to retail tariffs in the German electricity market over the 2007 to 2014 period. We find an average pass-through rate of around 60%, which significantly varies with demand factors: while the pass-through rate to baseline tariffs, where firms have...

We discuss the implications of two price zones, i.e. one northern and southern bidding area, on the German electricity market. In the northern zone, continuous capacity additions with low variable costs cause large regional supply surpluses in the market dispatch while conventional capacity...

Power systems with increasing shares of wind and solar power generation have higher capital and lower operational costs than traditional technologies. This increases the importance of the cost of finance for total system cost. We quantify how renewable policy design can influence cost of finance...

We propose a novel method to find Nash equilibria in games with binary decision variables by including compensation payments and incentive-compatibility constraints from non-cooperative game theory directly into an optimization framework in lieu of using first order conditions of a...

The reduced attractiveness of investments in reliable power plants under conditions of liberalized markets and the transition towards renewable energies has brought a discussion on capacity policies to Europe. We use a partial equilibrium model to compare important effects of three basic...

A shift from zonal pricing to smaller zones and nodal pricing improves efficiency and security of system operation. Resulting price changes do however also shift profits and surplus between and across generation and load. As individual actorscan lose, they might oppose any reform. We explore how...
