The Convergence Towards Day-Ahead Markets
The post highlights two converging trends in European power markets: day‑ahead prices have become markedly more volatile, largely due to a surge in solar generation, while short‑term imbalance prices are rapidly aligning with day‑ahead price patterns. Histograms from 2019 to 2024 show a broader price dispersion and a diminishing zero‑price peak, indicating deeper renewable penetration. Meanwhile, imbalance price distributions from 2024‑2026 display a clear dual‑peak shape that mirrors day‑ahead markets, and the spread between the two price series has narrowed, especially in 2025, with a modest seasonal uptick in spring.
Presentation on Recent Trends in Electricity Markets
The author presented a three‑part analysis of European electricity markets, focusing first on the rapid expansion of solar generation and battery storage. The second segment examined how these renewables are reshaping day‑ahead market pricing, pushing prices lower and altering the...
Listing the Risks Behind (Unpredicted) Solar Oversupply and the Resulting Extreme Low Prices
Solar capacity in the EU is growing at roughly 60 GW per year, creating frequent midday oversupply that can push electricity prices into negative territory. When actual generation exceeds day‑ahead forecasts by several gigawatts, markets have seen four‑digit negative prices, as...
MFRR Capacity - Germany 2025
Germany’s manual Frequency Restoration Reserve (mFRR) market generated about €60 million ($65 million) in 2025, but its tendered volumes have fallen to roughly 20% of aFRR capacity over the last decade. Downward mFRR prices dip to around €1/MW·h ($1.09) in winter, while...
Imbalance Price: Explanation of an Extreme Price in Germany
On March 1, Germany’s balancing market recorded an extreme negative imbalance price of ‑1474 €/MWh for a single 15‑minute interval. The price plunge was driven by an unexpected supply shortfall that outpaced intraday trading activity, leaving the system operator to procure balancing energy...
On Imbalance Prices
The blog explains how imbalance prices act as a 15‑minute settlement tool for Balance Responsible Parties (BRPs) in the European power market, bridging the gap between scheduled and real‑time generation. It contrasts three pricing scenarios—day‑ahead parity, punitive rates, and asymmetric...
