MFRR Capacity - Germany 2025

Key Takeaways

• mFRR market value ~ $65 million in 2025
• mFRR capacity now ~ 20% of aFRR downward
• Downward mFRR prices drop to ~$1.09/MW·h in winter
• Upward mFRR prices stay stable, rise with peak generation
• Seasonal shift favors aFRR over mFRR across Europe

Summary

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 upward prices stay relatively flat, rising only during peak generation periods. Seasonal patterns and high solar output in July further depress downward prices, underscoring the growing impact of renewables on reserve markets. The shift signals a clear preference for automated aFRR services across Germany.

Pulse Analysis

Germany’s manual Frequency Restoration Reserve (mFRR) market remains modest in absolute terms, but its 2025 financial turnover reached roughly €60 million – about $65 million at current exchange rates. Over the past fifteen years, tendered mFRR volumes have fallen sharply; today the service accounts for just over a quarter of upward aFRR capacity and roughly one‑fifth of downward aFRR. This contraction reflects a systemic preference for automated FRR (aFRR), which can be dispatched faster and with lower operational risk, pushing flexibility providers toward the more lucrative aFRR auctions.

Seasonality drives the mFRR price signal. In winter months, downward capacity can be purchased for as little as €1 per MW·h – roughly $1.09 – because abundant generation and low demand create excess supply. As spring arrives and conventional plants hit minimum output, the cost of reducing generation spikes, prompting some operators to accept generation losses offset by higher balancing payments. Upward mFRR, by contrast, shows a flatter annual curve, but still climbs during peak price periods when most plants are already operating at full capacity. Anomalously low July downward prices also coincided with a solar output surge, underscoring the growing influence of renewables on reserve markets.

The German experience highlights a broader European divergence: while countries such as Italy and the United Kingdom still rely heavily on mFRR or Replacement Reserve, Germany’s market is rapidly consolidating around aFRR. For flexibility traders, this means that mFRR opportunities are increasingly seasonal and price‑sensitive, rewarding participants who can mobilize capacity during winter downturns or capitalize on renewable‑driven price dips. Policymakers, meanwhile, must balance the efficiency gains of automated reserves with the need for a diversified toolkit that can absorb extreme generation swings, especially as Germany pushes toward a carbon‑neutral grid by 2030.
