This paper analyzes the trade-offs for using feed-in tariffs or tenders to remunerate different scales of solar photovoltaics (PV) projects. In recent years, European countries increasingly combined feed-in tariffs for small renewables systems with tenders for large installations. This study develops an analytic framework to quantify deployment effectiveness of responsive feed-in tariff adjustment ...

The European Union Emission Trading Scheme (EU ETS) has been implemented to provide a common climate policy instrument across European Union countries, to contribute to a credible investment perspective for low-carbon investors and support further European integration of energy markets. Thus the EU ETS is a key element of the European Energy Union.However, given the accumulation of a large surplus ...

Das reformierte Erneuerbare-Energien-Gesetz 2014 testet für Photovoltaik Freiflächenanlagen Ausschreibungen zur Festlegung der Marktprämien. Durch eine Preisfindung über Auktionen erhofft man sich eine effektivere Kontrolle des Ausbaus und eine höhere Effizienz der Förderung. Allerdings unterscheiden sich die internationalen Erfahrungen mit Ausschreibungen für erneuerbare Energien stark hinsichtlich ...

Der deutsche Atomausstieg in 2022 und die gleichzeitig stetig steigende Stromerzeugung durch fluktuierende Wind- und Sonnenenergie heizen in Deutschland, wie in Europa, seit geraumer Zeit eine Diskussion um die Versorgungssicherheitauf dem Strommarkt an. Dabei ist völlig unklar, wie Versorgungssicherheit – vor allem in der mittleren und langen Frist – gemessen werden soll. Das Fehlen eines klaren Konzeptes ...

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 ...

A shift from zonal to nodal pricing improves the efficiency of system operation. However, resulting price changes also shift surplus across generation and loads at different locations. As individual actors can lose, they might oppose any reform. We explore how allocation of financial transmission rights can be used to mitigate the distributional impact. The fundamental effects with regard to reference ...

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 ...

This article employs a simple model to describe bidding behavior in multi-unit uniform price procurement auctions when firms are capacity constrained. Using data from the New York City procurement auctions for power generating capacity, I find that firms use simple bidding strategies to coordinate on an equilibrium that extracts high rents for all bidders. I show theoretically and empirically that ...

This paper reviews the adjustments of the feed-in tariffs for new solar photovoltaic (PV) installations in Germany. As PV system prices declined rapidly since 2009, the German government implemented automatic mechanisms to adjust the remuneration level for new installations in response to deployment volumes. This paper develops an analytic model to simulate weekly installations of PV systems of up ...

Supply security in imperfect power markets is modelled under different market designs. In a uniform price auction for electricity with two firms, strategic behaviour may leave firms offering too few capacities and unable to supply all realized demand. Market design that relies on capacity markets increases available generation capacities for sufficiently high capacity prices and consequently decreases ...
