Benchmarking and Firm Heterogeneity: A Latent Class Analysis for German Electricity Distribution Companies

In January 2009, the German Federal Network Agency introduced incentive regulation for the electricity distribution sector based on results obtained from econometric and nonparametric benchmarking analysis. One main problem for the regulator in assigning the relative efficiency scores is unobserved firm-specific factors such as network and technological differences. Comparing the efficiency of different ...

Stromspeicher als zentrales Element der Integration von Strom aus erneuerbaren Energien (StoRES)

Ziel des Forschungsprojekts ist eine modellbasierte ökonomische Analyse verschiedener Strategien zur Integration erneuerbarer Energien in den deutschen Strommarkt. Dabei stehen Stromspeichertechnologien im Zentrum der Untersuchung. Mit Hilfe quantitativer, numerischer Strommarktmodelle wird der Bedarf an Speicherkapazitäten bei unterschiedlichen Rahmenbedingungen abgeschätzt. Untersucht werden...

Stromspeicher als zentrales Element der Integration von Strom aus erneuerbaren Energien (StoRES)

In this project, we carry out model-based economic analyses of different strategies for renewable energy integration in Germany, with a focus on storage technologies. Quantitative, numerical power market models are used to analyse the demand for storage capacities, the interaction between storage and transmission expansion, and the use of storage in oligopolistic markets. Moreover, we investigate...

Technical Aspects of Nodal Pricing

The expansion of renewable generation and closer integration of European power markets requires new tools and procedures for system operation. The US experience with nodal pricing offers options to tackle the emerging challenges, and thus may facilitate further integration of intermittent renewable generation technologies. At a one day roundtable hosted by CPI Berlin, experts from European transmission ...

How Emission Certificate Allocations Distort Fossil Investments: The German Example

Despite political activities to foster a low-carbon energy transition, Germany currently sees a considerable number of new coal power plants being added to its power mix. There are several possible drivers for this "dash for coal", but it is widely accepted that windfall profits gained through free allocation of ETS certificates play an important role. Yet the quantification of allocation-related investment ...

Modeling Strategic Electricity Storage: The Case of Pumped Hydro Storage in Germany

We study the strategic utilization of storage in imperfect electricity markets. We apply a game-theoretic Cournot model to the German power market and analyze different counterfactual and realistic cases of pumped hydro storage. Our main finding is that both storage utilization and storage-related welfare effects depend on storage ownership and the operator's involvement in conventional generation. ...

Kurz- und langfristige Auswirkungen des Ausbaus der erneuerbaren Energien auf den deutschen Arbeitsmarkt: Studie im Auftrag des Bundesministeriums für Umwelt, Naturschutz und Reaktorsicherheit

Modeling Storage and Demand Management in Electricity Distribution Grids

Storage devices and demand control may constitute beneficial tools to optimize electricity generation with a large share of intermittent resources through inter-temporal substitution of load. We quantify the related cost reductions in a simulation model of a simplified stylized medium-voltage grid (10kV) under uncertain demand and wind output. Benders Decomposition Method is applied to create a two-stage ...

Regulated Expansion of Electricity Transmission Networks: The Effects of Fluctuating Demand and Wind Generation

We study the performance of different regulatory approaches for the expansion of electricity transmission networks in the light of realistic demand patterns and fluctuating wind power. In particular, we are interested in the relative performance of a combined merchant-regulatory mechanism compared to a cost-based and a merchant-like approach. In contrast to earlier research, we explicitly include both ...

A Dynamic Incentive Mechanism for Transmission Expansion in Electricity Networks: Theory, Modeling, and Application

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. We show that the mechanism intertemporally promotes an investment pattern that relieves congestion, increases ...
