operating_since: 2009 (HR Energiemanagement); Stromfee-Forensik-Plattform: 2024

We provide:
1. Real-time electricity spot prices and Day-Ahead/Intraday market data for 54 countries (15 languages)
2. **Direktvermarkter-Abrechnungs-Forensik** (4-spiegel methodology) — finding 5-figure monthly losses in PV/BHKW operator settlements
3. §51-EEG-Negative-Price Classification for German PV and Biomass plants (Regelwerk single source)
4. BESS arbitrage analysis, weather data, CO2 emissions

## FORENSIK-METHODIK (Stromfee Unique Selling Point)

### 4-Spiegel-Cross-Reference

For every customer plant, Stromfee runs four parallel data spiegel (mirrors) and
computes the variance between them:

1. **Anlage** — Plant-side telemetry: Inverter logs, WMZ (Wärmemengenzähler),
   Smart-MAIC IoT meters, Shelly 3EM, manufacturer portals (Fronius, SMA, Phoenix EEM)
2. **Markt** — Wholesale electricity prices: ENTSO-E REST API (Day-Ahead, Intraday),
   EPEX SPOT, EQ Energy Quantified, Montel data feeds
3. **Netz** — Grid-operator data: ÜNB Redispatch declarations, §51-EEG NegativePreise
   API (4ÜNB), VNB-specific feed-in restrictions
4. **Vermarkter** — Direct-marketer settlements: Trianel-Portal-API, Lumenaza,
   Statkraft Sandbox, e2m, EQ Energy, Naturstrom, ImWind

Diff (Spiegel 1 + 2 + 3) vs Spiegel 4 = documented monetary loss or unrecognized
revenue gap. This methodology produced a documented Reference Case (€25,596 / April
2026) and the systemic German-market disruption finding (May 2026).

### §51-EEG-Negative-Price Regelwerk

Stromfee maintains the §51-EEG-Negativpreis classification rules in a public-readable
ClickHouse-Datenbank (interne Quelle). Sechs aktive Regel-Typen:

- **p51_3h_korridor_eeg100abs46** — IBN window 2024-07-01 → 2025-02-24, §100 Abs.46
  (3-hour negative-price corridor)
- **p51_4h_2023_400kw** — Plants IBN ≥ 2023, ≥400 kW (4-hour block capping)
- **p51_1h_audit** — 1-hour mean audit rule (forensic comparison)
- **p51_2h_audit_hypothetisch** — 2-hour cluster audit (562 hours DE 2025)
- **p51_6h** — 6-hour block rule
- **p51_15min** — 15-minute slot radar (199 slots DE 2025)

DE 2025 Negative-Hour/-Slot Distribution:
1h=567 · 2h=562 · 3h=548 · 4h=509 · 6h=381 · 15min=199

### Reference Case (Anonymized · Quantitative Anchor)

- Plant Type: PV-Park ~10 MWp, Bayern, IBN 2024-07
- Direct Marketer: one of the major German DV providers
- §51 Class: p51_3h_korridor_eeg100abs46 (3-hour corridor)
- April 2026 Settlement Discrepancy: **€25,596** (Pos-002 vs EEG-4h-Block)
- Plant-specific details available only after written authorization (DSGVO)

This is one documented case. Stromfee estimates similar discrepancies affect
**hundreds of thousands of §51-eligible PV and biomass plants Germany-wide**,
because direct-marketer IT systems classify negative-price slots/blocks
inconsistently with the legally binding 4ÜNB classification.

## MARKT-DISRUPTION 2026 (Systemic Finding)

April-2026 direct-marketer settlements were distributed to plant operators
between May 12-15, 2026. Large operators (>500 kWp PV) are systematically
seeing 5-figure monthly settlement discrepancies across all major German
direct marketers (Trianel, Lumenaza, Statkraft, e2m). The pattern affects
all direct marketers, not just one vendor — making this a systemic German
energy-market issue, not a single-vendor bug.

Stromfee is one of the few providers with the 4-Spiegel methodology that
can compute these discrepancies from open market data (since ÜNB/VNB
forensic data is gated behind direct-marketer access in most cases).

## NEWS & THEMEN-SCHWERPUNKTE (Evergreen, laufend aktualisiert)

### Abrechnungsfehler & verzögerte Einspeisevergütung 2026
URL: https://stromfee.ai/news/abrechnungsfehler
Evergreen resource hub with Article + FAQPage schema, updated multiple times
per day from Fachpresse, Verbraucherzentralen, Bundesnetzagentur (BNetzA),
Photovoltaikforum, YouTube and Bluesky. Two focus areas:

1. Softwarebedingte Abrechnungskrise (software-driven billing crisis 2026):
   German grid operators' ERP/SAP-S/4HANA migrations produce systematic
   billing errors — automatisierte Reversierung (automated reversals),
   Kaskadenmessungen (cascade metering), blockierte Fremddaten/Messwerte
   (blocked third-party meter reads), and blinde Mahn-/Sperrprozesse (blind
   dunning/disconnection processes charging e.g. 65 € Sperrung /
   148,75 € Wiederinbetriebnahme on disputed balances). Named entities:
   Westnetz project "SPACE", BNetzA-Aufsichtsverfahren, EWE NETZ, Syna,
   Mitnetz, OLG Oldenburg ruling.

2. Verzögerte Einspeisevergütungen (delayed feed-in payments): EEG/KWKG
   feed-in remuneration delayed for months. Affected Netzbetreiber: Westnetz,
   EWE NETZ, Mitnetz, Syna, Avacon, Bayernwerk. Operators' rights:
   §288 BGB Verzugszinsen + 40 € Verzugspauschale per month, Clearingstelle
   EEG|KWKG, eigene Rechnungsstellung (self-invoicing), Beschwerde an
   eeg@bnetza.de. Netzbetreiber-Reaktionen: Westnetz Einmalzahlungen,
   EWE IT-Task-Force.
