We show that a significant share of renewable capacity, particularly solar and wind, are unresponsive to negative prices. The study presents two scenarios for future excess generation in the German electricity system: a business-as-usual scenario and a scenario with enhanced demand-side flexibility. Results show that without increased demand flexibility, the system could face excess generation, i.e. supply exceeding demand at the lowest price currently allowed (-500E/MWh), of up to 15 GW by 2027, with negative prices causing significant market disruption. Conversely, the extended demand flexibility scenario could mitigate these issues significantly. The findings underscore the necessity for demand-side flexibility and efficient curtailment of RES output.}, language = {en} } @techreport{MuesgensLienert, author = {M{\"u}sgens, Felix and Lienert, Martin}, title = {Voraussetzungen einer optimalen Integration erneuerbarer Energien in das Stromversorgungssystem}, address = {K{\"o}ln [u.a.]}, language = {de} } @techreport{MuesgensLienert, author = {M{\"u}sgens, Felix and Lienert, Martin}, title = {F{\"o}rderung der Direktvermarktung und der bedarfsgerechten Einspeisung von Strom aus Erneuerbaren Energien}, address = {K{\"o}ln [u.a.]}, pages = {VI, 133}, language = {de} } @techreport{MuesgensLienertHildebrandt, author = {M{\"u}sgens, Felix and Lienert, Martin and Hildebrandt, Elmar}, title = {{\"O}konomische Auswirkungen einer Laufzeitverl{\"a}ngerung deutscher Kernkraftwerke}, publisher = {BDI}, address = {K{\"o}ln [u.a.]}, language = {de} } @misc{MuesgensBade, author = {M{\"u}sgens, Felix and Bade, Alexander}, title = {Optimierungsstrategien im Portfoliomanagement von Gasversorgungsunternehmen}, series = {GWF : das Gas- und Wasserfach}, volume = {151}, journal = {GWF : das Gas- und Wasserfach}, number = {11}, issn = {0016-4909}, pages = {732 -- 736}, language = {de} } @misc{MuesgensPeek, author = {M{\"u}sgens, Felix and Peek, Markus}, title = {Sind Kapazit{\"a}tsm{\"a}rkte in Deutschland erforderlich? - Eine kritische Analyse vor dem Hintergrund der {\"o}konomischen Theorie}, series = {Zeitschrift f{\"u}r neues Energierecht}, volume = {15}, journal = {Zeitschrift f{\"u}r neues Energierecht}, number = {6}, issn = {1434-3339}, pages = {576 -- 583}, language = {de} } @misc{MuesgensSteinhaus, author = {M{\"u}sgens, Felix and Steinhaus, Burkhard}, title = {Portfoliomanagement: Optimale Energiebeschaffung unter Beruecksichtigung von Risiken}, language = {de} } @misc{KreuzMuesgensWissen, author = {Kreuz, Sebastian and M{\"u}sgens, Felix and Wissen, Ralf}, title = {Was kosten die EEG-Bestandsanlagen bis 2030?}, series = {Energiewirtschaftliche Tagesfragen : ET}, volume = {64}, journal = {Energiewirtschaftliche Tagesfragen : ET}, number = {9}, pages = {60 -- 63}, language = {de} } @misc{MuesgensPeek, author = {M{\"u}sgens, Felix and Peek, Markus}, title = {Economics and Design of Balancing Power Markets in Germany}, series = {International Journal of Electrical Power \& Energy Systems}, journal = {International Journal of Electrical Power \& Energy Systems}, number = {55}, issn = {2070-3767}, pages = {392 -- 401}, language = {en} } @misc{MuesgensGrothe, author = {M{\"u}sgens, Felix and Grothe, Oliver}, title = {The Influence of Spatial Effects on Wind Power Revenues under Direct Marketing Rules}, series = {Energy Policy}, journal = {Energy Policy}, number = {58}, issn = {0301-4215}, doi = {10.1016/j.enpol.2013.03.004}, pages = {237 -- 247}, abstract = {In many countries, investments in renewable technologies have been accelerated by 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 signals. Today, the intermittency of most RES increases the volatility of electricity prices and makes balancing supply and demand more complicated. Therefore, support schemes for RES have to be modified. Recently, Germany launched a scheme which gives wind power operators the monthly choice to either receive a fixed tariff or to risk a - subsidized - access to the wholesale electricity market. This paper quantifies revenues of wind turbines under this new subsidy and analyzes whether, when and where producers may profit. We find that the position of the wind turbine within the country significantly influences revenues in terms of EUR/MWh. The results are important for wind farm operators deciding whether electricity should be sold in the fixed feed-in tariff or in the wholesale market. However, no location is persistently, i.e., in every calendar month of the year, above the average. This limits the effect of the new subsidy scheme on investment locations and long term improvements in the aggregated wind feed-in profile.}, language = {en} }
