Curtailment-Forensik-Software
— Welt-Competitor-Tracker.
Who in the world offers a curtailment-forensics tracker like Stromfee.ai?
Mapped across 7 vendor categories against 9 functions —
decoded through the 4-mirror lens (plant × market × grid × marketer).
Bottom line: nobody combines scale + depth without the structural conflict
that direct marketers are themselves big customers.

0 / 6competitors that do marketer cross-check (setpoint vs contract)
~300 GWPower Factors-scale — but with DV-conflict (Stromfee gap is real)
⚠ The market-gap finding from 30 countries surveyed (May 2026):
Asset performance management (Power Factors, meteocontrol, SenseHawk, Alectris, GreenPowerMonitor)
measures plant performance against expectation — but accepts the marketer setpoint as given.
It does not test whether that setpoint was contractually legitimate. Direct marketers and aggregators
(Trianel, Statkraft, Dexter, Sympower, Next Kraftwerke) are their largest customers; building a
forensics product against their own customers is a structural conflict. This is why a real
Stromfee-equivalent does not exist — and why operator-side legal counsel does the work manually
at €8–25 k per plant per year.
Die 4-Spiegel-Linse · wie wir jeden Anbieter dekodieren
Inspired by the Stromfee Block-Rule-Decoder (BRD) for German §51 EEG forensics. Each vendor is
measured against the four cross-reference layers needed to prove unjustified curtailment.
1Plant
15-min real generation from SCADA (meteocontrol VCOM, Solar-Log, FusionSolar, Power Factors) cross-referenced with weather (Open-Meteo, Solcast).
2Market
Day-Ahead spot (ENTSO-E, EPEX, IEX, NEM, JEPX, CCEE-PLD) for legitimacy check: was there a negative-price trigger (§51 EEG) or not?
3Grid
TSO dispatch orders (Netztransparenz, ÜNB, Grid-India SLDC, ONS BR) — was the curtailment grid-technically justified, or just commercial?
4Marketer
Off-taker settlement files (Trianel-MSCONS, SECI PSA, CCEE constrained-off-apuração) — did the marketer report the curtailment correctly and compensate fully?

The Stromfee USP is structurally unique:
Power Factors has scale (300 GW) but cannot build a marketer-cross-check tool without losing its
direct-marketer customers. Expert witnesses have the depth but no SaaS skaling. Stromfee
closes that gap with the 4-mirror methodology + operator-centric buyer position.
Tensor Energy (Japan) is the only vendor moving in this direction — but Japan-only and not
dispute-evidence focused. India's NSEFI runs an aggregate tracker but no plant-IST/contract layer.
Australia's WattClarity has the market and grid mirrors but no marketer layer.

Stromfee.aiGermany · BielefeldREFERENCE
Forensic SaaS platform for PV plant owners against unjustified curtailment by direct marketers.
4-mirror methodology: plant × market × grid × marketer with mandatory cross-reference at 15-min
level. Pilot reference: 9,998 MWp Lotter Schweighof II Bavaria (1.5 years live data).
ClickHouse pipeline + ECharts visualisation. 30-country world study + India + Brazil detail-pages.
Preise: €3-6 k/plant/year forensics subscription · Abdeckung: DE primary, AT 1:1 portable, IN+BR pipeline · Output: expert-witness ready forensic tables, cash-recovery calculator
Power Factors / Greenbyte / InaccessUSA · globalAPM
Largest independent solar asset-performance-management platform. ~300 GW under management,
18,000 sites. Loss-waterfall classifies losses into Performance / Curtailment / Downtime.
Gap: accepts marketer setpoint as given, does not test contract legitimacy.
Direct marketers like Statkraft, EnBW, MVV are largest customers — structural conflict prevents
building operator-side forensics. Acquired Greenbyte (SE) 2021 and Inaccess (GR/UK) 2024.
Customer base: IPP + asset owner + direct marketer · Preise: SaaS subscription per GW
meteocontrolGermany · AugsburgSCADA
VCOM Cloud platform with ~60 GW under management. Stores both grid-operator setpoint AND
direct-marketer setpoint in parallel — but
does not classify whether either
setpoint is contractually legitimate. Stromfee uses VCOM as data source for its own
Plant-Mirror; the missing legitimacy classification is exactly the Stromfee differentiator.
India subsidiary with ~3 GW.

NSEFI Curtailment-TrackerIndia · New DelhiAggregate
National Solar Energy Federation of India publishes a state-level curtailment tracker
(142 member organisations, ~95 % of installed solar capacity). Aggregate state-level data,
no plant-IST and no contract layer. Excellent first-contact entry
for Stromfee market entry into India. CEO Subrahmanyam Pulipaka, Chairman Pranav Mehta.
Access: free for members · Granularity: state-level monthly
WattClarity / NEMOSIS / AEMO QEDAustralia · NEMMarket+Grid
Most transparent ecosystem of the region. WattClarity (commercial analytics on AEMO data),
NEMOSIS (open-source Python library), Solcast (ARENA-funded solar nowcasting).
5-minute-settlement since 1 Oct 2021, AEMO publishes Quarterly Energy Dynamics with detailed
curtailment data.
Market and grid mirrors very good, but no marketer-balancing-circle
forensics — because Australia's NEM doesn't have the same DV mandate as Germany's EEG.
Q4/2025: utility solar gave up 18 % of available generation, South Australia 59 %.
Data source: AEMO public · Customer base: traders, IPP, asset managers
Tensor EnergyJapan · TokyoFIP cloud
Closest international competitor. Commercial cloud platform for FIP-asset owners in Japan
(FIP-certified capacity 3.8 GW / 1,889 projects per March 2025). Includes vermarketing logic,
BESS optimisation.
Japan-only · not dispute-evidence focused · single-mirror
depth. If Stromfee enters Japan, Tensor would be the direct competitor.
Scope: FIP-asset owners post-04/2022 · Preise: SaaS · Acquisition risk for Stromfee: Tensor could expand cross-border
Expert Witnesses · r2b · Idam · PSRglobalManual
The current way forensics gets done today — but manually, per project, expensive. r2b energy
consulting (DE) for arbitration, Idam Infrastructure (IN) for Sector-30+ years experience,
PSR Consultoria (BR) for SDDP/OptGen models.

Methodischer Hinweis
This comparison is based on the Stromfee Welt-Studie May 2026 (30 countries,
178 sources audited). Negative finding: in NONE of the 30 markets a Stromfee-equivalent
forensics product was found that combines (a) automated 15-min plant-IST cross-reference,
(b) market trigger validation, (c) grid dispatch validation, and (d) marketer setpoint vs
contract validation, with (e) expert-witness ready legal output. Vendors marked "partial"
cover one or two layers; vendors marked "no" cover none.
Open question · LEAP-71 falsification: Power Factors could plausibly build
a marketer-cross-check feature for non-customer IPPs by acquisition (e.g. acquiring an
operator-side boutique). This is the most likely competitive risk in 18-36 months. Stromfee's
counter-strategy: build defensibility moat through depth of EU §51-EEG / Indian Must-Run /
Brazilian Lei 15.269/2025 legal frameworks before that happens.
