Katherina Reiche and the Myth of Solar Subsidies: Why Operators Do Not Receive 7 Cents per Kilowatt-Hour in State Support

Why It Matters

The policy shift reshapes cost allocation in Germany’s renewable energy market, potentially slowing rooftop solar growth and altering revenue streams for grid operators and households.

Key Takeaways

• Difference settlement replaces direct cash subsidy.
• Only full‑feed‑in operators receive 7‑8 ct/kWh.
• Older 2006‑2012 contracts dominate EEG costs.
• Self‑consumption reduces network fees, boosting households.
• Reform may shift benefits to large grid companies.

Pulse Analysis

Germany’s Renewable Energy Act (EEG) uses a difference‑settlement model, where the state only bridges the gap between the market price on the 15‑minute exchange and a guaranteed minimum remuneration. This mechanism is often mischaracterised as a direct subsidy of 7‑8 cents per kilowatt‑hour, but the actual payment flows back to the EEG account when market prices exceed the floor. Understanding this nuance is essential for investors and policymakers assessing the true fiscal impact of solar support schemes.

The upcoming phase‑out of feed‑in tariffs for new rooftop PV installations, championed by Minister Katherina Reiche, is unlikely to generate the headline‑grabbing savings suggested by some analysts. The bulk of EEG expenditures are tied to legacy contracts signed between 2006 and 2012, which still pay more than 50 cents/kWh and will only expire between 2026 and 2032. Consequently, the short‑term budget relief from removing the 7‑8 ct/kWh floor is marginal, while the long‑term cost curve remains dominated by these high‑rate agreements.

Beyond the accounting details, the reform reshapes market incentives. By eliminating the guaranteed remuneration, private owners must market excess electricity themselves, increasing administrative burdens and potentially discouraging new installations. Fewer rooftop systems mean reduced self‑consumption, higher grid demand, and increased revenue for large transmission operators. The policy therefore tilts benefits toward incumbent grid companies, while private participants face higher barriers, a shift that could slow Germany’s decentralized renewable expansion.
