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} } @misc{RadkeMuesgens, author = {Radke, Silvian M. and M{\"u}sgens, Felix}, title = {Mitigating negative electricity prices - batteries or flexibility in wind and solar?}, series = {2025 21st International Conference on the European Energy Market (EEM)}, journal = {2025 21st International Conference on the European Energy Market (EEM)}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {979-8-3315-1278-1}, issn = {2165-4093}, doi = {10.1109/EEM64765.2025.11050208}, pages = {1 -- 6}, abstract = {This paper analyses the influence of battery storage systems and high shares of price-inelastic generation on electricity prices. Within the last years, negative wholesale electricity prices have become a relevant topic in many electricity systems around the world. We develop a linear cost minimization model to analyze the relationship between price-inelastic generation and battery storage. We parameterize the model with three different scenarios which describe the German electricity market in the year 2030. Our model shows that both additional storage capacities and more flexible renewable generation are necessary to avoid high volatility in electricity prices and thereby reduce the number of hours with negative electricity prices.}, language = {en} }
