This article analyses the flexibility of the German power market with respect to the integration of an increasing share of electricity from renewable energy sources. Flexibility limiting system components, which cause negative prices are explained and illustrated for the German market. Then, the...

Morocco, Algeria and Tunisia, the three countries of the North African Maghreb region, are showing increased efforts to integrate renewable electricity into their power markets. Like many other countries, they have pronounced renewable energy targets, defining future shares of “green”...

The investment decision on the placement of wind turbines is, neglecting legal formalities, mainly driven by the aim to maximize the expected annual energy production of single turbines. The result is a concentration of wind farms at locations with high average wind speed. While this strategy...

In many countries worldwide, investment in renewable technologies has been accelerated by the introduction of fixed feed-in tariffs for electricity from renewable energy sources (RES). While fixed tariffs accomplish this purpose, they lack incentives to align the RES production with price...

We examine the effect of energy prices and technological knowledge on innovation in green energy technologies. In doing so, we consider both demand-pull effects, which induce innovative activity by increasing the expected value of innovations, and technology-push effects, which drive innovative...

Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MV el) of renewable energy technologies. As shown by Lamont (2008), the MV el of wind and solar power units depends on their...

Renewable energy (RES-E) support schemes have to meet two requirements in order to lead to a cost-efficient renewable energy mix. First, RES-E support schemes need to expose RES-E producers to the price signal of the wholesale market, which incentivizes investors to account not only for the...

Elektrische Energie ist nur unter erheblichen technischen und ökonomischen Aufwand zu speichern. Nichtsdestotrotz muss für eine zuverlässige Versorgung der Gesellschaft mit elektrischer Energie ein ständiges Gleichgewicht von Angebot und Nachfrage gewährleistet werden können. Aus diesem...

Ziel dieses Papers ist es, die derzeitige Diskussion bzgl. des sog. Merit-Order Effektes der erneuerbaren Energien auf den Strompreis kritisch zu beleuchten. Veröffentlichungen, welche diesen Effekt quantifizieren, weisen für die Jahre 2005 und 2006 einen Großhandels-Strompreis senkenden...

Ongoing climate change affects complex and long-lived infrastructures like electricity systems. Particularly for decarbonized electricity systems based on variable renewable energies, there is a variety of impact mechanisms working differently in size and direction. Main impacts for Europe...
