68. Future Day-Ahead Electricity Price Spreads in Germany: Drivers, Forecasting, and Flexibility Scenarios

Ralph Butter

3/27/26, 2:30 PM

Large and volatile within-day spreads in the day-ahead electricity market, defined as the daily maximum minus the minimum of hourly day-ahead prices, shape arbitrage revenues and therefore investment incentives for flexibility resources such as batteries, demand response, and vehicle-to-grid (V2G). They also provide a market-based signal of scarcity and surplus in power systems with rising...

81. Navigating Uncertainty: Renewable Bidding and Price Premia in Sequential Electricity Markets

Julian Keutz

3/27/26, 2:50 PM

Sequential wholesale electricity markets are designed to enhance allocative efficiency by allowing market participants to adjust positions as information unfolds over time. In theory, prices across these sequential stages, e.g., the Day-Ahead and Intraday markets, should converge in expectation. Empirically, however, systematic price premia persist, and in high-renewable systems such as...

94. Hedging Renewables with Location Spreads

Tobias Kargus (Karlsruhe Institute of Technology)

In countries like Germany, renewable production accounts for a dominant share of the overall production (see Bundesnetzagentur SMARD (2025)). As a consequence, the risk profile of power producers has shifted: instead of relying primarily on controllable thermal power plants with...
