Der Strommarkt als soziale Institution: eine erweiterte Perspektive auf die deutsche Diskussion um Kapazitätsmechanismen

Ausgangspunkt für Forderungen nach einer Einführung von Kapazitätsmechanismen im deutschen Strommarkt ist die Beobachtung, dass das gegenwärtige Investitionsverhalten der Marktakteure zu einem unzureichenden Niveau der Stromversorgungssicherheit führen könnte. In dem vorliegenden Beitrag wird die enge logische Verknüpfung zwischen Investitionstätigkeit und einer Änderung des formellen Marktdesigns ...

Improving Congestion Management: How to Faciliate the Integration of Renewable Generation in Germany

In this paper the German congestion management regime is analyzed and future congestion management costs are assessed given a higher share of intermittent renewable generation. In this context, cost-based re-dispatching of power plants and technical flexibility through topology optimization are considered as market-based and technical congestion management methods. To replicate the current market regime ...

Development Scenarios for the North and Baltic Seas Grid: A Welfare Economic Analysis

The North and Baltic Seas Grid is one of the largest pan-European infrastructure projects, increasing the potential of harnessing large amounts of renewable energy. This paper addresses the economic implications of different development scenarios of the North and Baltic Seas Grid on individual countries and stakeholders which may raise concerns about the implementation in largely nationally dominated ...

Wohnimmobilien in Großstädten: Kaufpreise steigen auch 2014 schneller als Mieten

Die Kaufpreise für Eigentumswohnungen sind seit Beginn des Jahres 2010 um durchschnittlich sechs Prozent gegenüber dem jeweiligen Vorjahresquartal gestiegen. Die Wachstumsraten der Mietpreise haben mit vier Prozent deutlich weniger zugenommen, liegen aber ebenfalls oberhalb der allgemeinen Teuerungsrate. Das ergibt eine aktuelle Analyse des DIW Berlin, für die die Preisentwicklung im Immobiliensektor ...

Amerika im Fracking-Boom: langfristiges Eldorado für energieintensive Industrien? Kommentar

Towards Optimal Regulation of Transmission Network Investment under Renewable Integration

We analyze regulatory regimes for electricity transmission investment in the context of transformation of the power system towards renewable energy. We study three distinctive developments of the generation mix with different implications on network congestion, which may be either of temporary or permanent nature. We address the relative performance of a combined merchant-regulatory price-cap mechanism, ...

From Boom to Bust? A Critical Look at US Shale Gas Projections

US shale gas production is generally expected to continue its fast rise. However, a cautious evaluation is needed. Shale gas resource estimates are potentially overoptimistic and it is uncertain to which extent they can be produced economically. Moreover, the adverse environmental effects of ever more wells to be drilled may lead to a fall in public acceptance and a strengthening of regulation. The ...

Price Guarantees, Consumer Search, and Hassle Costs

The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price guarantees will have no effect on prices if search costs are low, hassle costs are high and the number of uninformed ...

Crop Failures and Export Tariffs

We analyse a stylized model of the world grain market characterized by a small oligopoly of traders with market power on both the supply and demand side. Crops are stochastic and exporting countries can impose export tariffs to protect domestic food prices. Our first results is that export tariffs are strategic complements and that for poor harvests equilibrium tariffs can explode (shedding some light ...

Renewable Electric Energy Integration: Quantifying the Value of Design of Markets for International Transmission Capacity

Integrating large quantities of variable renewable electricity generation remains a political and operational challenge. One of the main obstacles in Europe to installing at least 200 GWs of power from variable renewable sources is how to deal with the insufficient network capacity and the congestion that will result from new flow patterns. We model the current methodology for controlling congestion ...
