An Analysis of a Forward Capacity Market with Long-Term Contracts

We analyze the effectiveness of a forward capacity market (FCM) with long-term contracts in an electricity market in the presence of a growing share of renewable energy. An agent-based model is used for this analysis. Capacity markets can compensate for the deteriorating incentive to invest in controllable power plants when the share of variable renewable energy sources grows, but may create volatile ...

Cross-Border Effects of Capacity Mechanisms in Interconnected Power Systems

The cross-border effects of a capacity market and a strategic reserve in interconnected electricity markets are modeled using an agent-based modeling methodology. Both capacity mechanisms improve the security of supply and reduce consumer costs. Our results indicate that interconnections do not affect the effectiveness of a capacity market, while a strategic reserve is affected negatively. The neighboring ...

Environmental Policies and Productivity Growth: Evidence across Industries and Firms

This paper investigates the impact of changes in environmental policy stringency on industry- and firm-level productivity growth in a panel of OECD countries. To test the strong version of the Porter Hypothesis (PH), we extend a neo-Schumpeterian productivity model to allow for effects of environmental policies. We use a new environmental policy stringency (EPS) index and let the effect of countries׳ ...

Simulating Climate and Energy Policy with Agent-Based Modelling: the Energy Modelling Laboratory (Emlab)

We present an approach to simulate climate and energy policy for the EU, using a flexible and modular agent-based modelling approach and a toolbox, called the Energy Modelling Laboratory (EMLab). The paper shortly reviews core challenges and approaches for modelling climate and energy policy in light of the energy transition. Afterwards, we present an agent-based model of investment in power generation ...

Is the German Retail Gasoline Market Competitive? A Spatial-Temporal Analysis Using Quantile Regression

We explore whether noncompetitive pricing prevails in Germany’s retail gasoline market by examining the influence of the crude oil price on the retail gasoline price, focusing specifically on how this influence varies according to the brand and to the degree of competition in the vicinity of the station. Our analysis identifies several factors other than cost—including the absence of nearby competitors ...

Power Markets with Renewables: New Perspectives for the European Target Model

We discuss at the European example how power market design evolves with increasing shares of intermittent renewables. Short-term markets and system operation have to accommodate for the different needs of renewable and conventional generation assets and flexibility options. This can be achieved by pooling resources over larger geographic areas through common auction platforms, realizing the full flexibility ...

Estimating Alternative Technology Sets in Nonparametric Efficiency Analysis: Restriction Tests for Panel and Clustered Data

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs. Simar and Wilson (Commun Stat Simul Comput 30(1):159–184, 2001) and Schubert and Simar (J Prod Anal 36(1):55–69, ...

A Coordinated Strategic Reserve to Safeguard the European Energy Transition

In Germany and beyond, various capacity mechanisms are currently being discussed with a view to improving the security of electricity supply. One of these mechanisms is a strategic reserve that retains generation capacity for use in times of critical supply shortage. We argue that strategic reserves have specific advantages compared to other capacity mechanisms in the context of the European energy ...

The Effectiveness of a Strategic Reserve in the Presence of a High Portfolio Share of Renewable Energy Sources

To ensure sufficient investment in electricity generation capacity, mechanisms such as strategic reserves are being considered or already implemented. We analyze the effectiveness of a strategic reserve in the presence of a growing portfolio share of renewable energy sources (RES) with EMLab-Generation, an agent-based electricity market model. A strategic reserve can stabilize investment, but within ...
