Negativpreisperioden - Subventionsverlust durch Solarspitzengesetz

Updated: Apr 20263 verified sources

Definition

Solar peak pricing periods during high solar generation compress wholesale electricity prices to negative territory. Systems without intelligent metering (iMSys) face 60% feed-in power limitation. Operators forgo both EEG subsidy and generation value during negative-price windows—typically 20–80 hours/year in German grid, increasing with renewable penetration.

Key Findings

Financial Impact: €800–€2,100 annually per 10 kWp system (8–12% of annual EEG subsidy revenue forgone)
Frequency: Recurring annually; frequency of negative-price events increasing (estimated 50–150 hours/year in 2025–2026 per grid zone)
Root Cause: Regulatory subsidy suspension during negative pricing + feed-in curtailment without compensatory revenue mechanism (e.g., storage dispatch revenue or grid services pricing)

Why This Matters

This pain point represents a significant opportunity for B2B solutions targeting Solar Electric Power Generation.
