Die steile Entwicklung der Gaspreise hat die Strompreise im vergangenen Jahr in bislang ungeahnte Höhen klettern lassen. Satte Zusatzgewinne gemacht haben die Betreiber von Anlagen für erneuerbare Energien - und zwar indirekt auf Kosten der VerbraucherInnen, die kräftig draufzahlen mussten....

Carbon reduction and renewable energy policies are implemented in Europe to improve the sustainability of the electricity sector while achieving security of supply. We investigate the interactions between these policies using a dynamic investment model. Our analysis indicates that both policies...

The cost of renewable energy technology has plunged in recent years. But the extent to which electricity consumers can benefit from the reduced costs depends on the design of renewable remuneration mechanisms. Calculations of a financing model show that the current sliding premium is leading to...

Cost of renewable energies have dropped, approaching wholesale power price levels. As a result, the role of renewable energy policy design is shifting - from covering incremental costs towards facilitating risk-hedging. An analytical model of the financing structure of renewable investment...

Short-term electricity markets are key to an efficient production by generation units. We develop a two-period model to assess different bidding formats to determine for each bidding format the optimal bidding strategy of competitive generators facing price-uncertainty. We compare the results...

The recent low CO2 prices in the European Union Emission Trading Scheme (EU ETS) have triggered a discussion whether the EU ETS needs to be adjusted. We study the effects of CO2 price floors and a price ceiling on the dynamic investment pathway of two interlinked electricity markets (loosely...

Designing auctions that favor low resource quality installations allows countries to geographically diversify their renewable energy production, while lowering payments to low-cost producers. In this paper, we develop a stylized model showing that a discriminatory auction design favoring...
