Responsive Adjustment of Feed-in Tariffs to Dynamic PV Technology Development

This paper reviews the adjustments of the feed-in tariff for new solar photovoltaics (PV) installations in Germany. As PV system prices declined rapidly over the last years, the German government implemented automatic mechanisms to adjust the support level for new installations in response to deployment volumes. This paper develops an analytic model to simulate weekly installations of PV systems ?30 ...

The Proposed Adjustment of Germany's Renewable Energy Law: A Critical Assessment

Support through the German Renewable Energy Sources Act (EEG) has led, in the past few years, to an unexpectedly wide expansion of systems for generating solar power (photovoltaics) because the system prices for photovoltaic (PV) systems have fallen at a faster rate than the solar power feed-in tariffs guaranteed by the law. This has also contributed to a substantial increase in the EEG surcharge to ...

Targeted Support for New Photovoltaic Installations Requires Flexible and Regular Adjustments

Feed-in tariffs have proven to be an effective instrument in supporting renewable energies. As a result of the dynamic price trend of photovoltaics, the actual number of systems installed has repeatedly exceeded initial government targets. Therefore, the support for new solar power installations by the German Renewable Energy Sources Act (EEG) has been adjusted several times. Based on the experiences ...

Solarstromförderung: drastische Einschnitte nicht sinnvoll

Die Förderung durch das Erneuerbare-Energien-Gesetz (EEG) hat in den letzten Jahren zu einem unerwartet starken Ausbau von Anlagen zur Erzeugung von Solarstrom (Photovoltaik) geführt, weil die Systempreise der Photovoltaikanlagen schneller gesunken sind als die gesetzlich garantierten Vergütungssätze. Dies hat mit dazu beigetragen, dass die von Stromverbrauchern zu zahlende EEG-Umlage stark gestiegen ...

Zielgerichtete Solarstromförderung erfordert häufige und flexible Anpassungen

Einspeisevergütungen haben sich als wirksames Instrument zur Förderung erneuerbarer Energien erwiesen. Aufgrund der dynamischen Preisentwicklung der Photovoltaik wurden wiederholt mehr Anlagen installiert, als zunächst als politisches Ziel formuliert worden war. Deswegen wurde die Solarstromförderung durch das Erneuerbare-Energien-Gesetz (EEG) mehrfach angepasst. Auf Grundlage der Erfahrungen mit diesen ...

Banking of Surplus Emissions Allowances: Does the Volume Matter?

In the European Emission Trading scheme the supply of allowances exceeds emissions - cumulating, according to our estimates, in a surplus of 2.7 billion tonnes by 2013/2014. We find that initially the surplus was acquired by power companies so as to hedge future carbon costs. As the surplus exceeds this hedging demand, additional allowances need to be acquired as speculative investment. This requires ...

Zum Netzentwicklungsplan (NEP) Strom 2012: Analyse des Entwurfs der Übertragungsnetzbetreiber vom 30. Mai 2012 ; Stellungnahme für die Konsultation der Übertragungsnetzbetreiber

Untersuchung des Energiesparpotentials für das Nachfolgemodell ab dem Jahr 2013ff zu den Steuerbegünstigungen für Unternehmen des Produzierenden Gewerbes sowie der Land- und Forstwirtschaft bei der Energie- und Stromsteuer: Forschungsvorhaben fe 5/11 im Auftrag des Bundesministeriums der Finanzen ; Endbericht

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 ...

Survey of Photovoltaic Industry and Policy in Germany and China

As building-integrated photovoltaic (PV) solutions can meet around one-third of electricity demand in Germany and China, both countries are interested in exploring this potential. PV technologies have demonstrated significant price reductions, but large-scale global application of PV requires further technology improvements and cost reductions along the value chain. We analyze policies in Germany and ...
