What 4cast Gmbh & Co. Kg does

4cast GmbH & Co. KG is a Potsdam-based, DAkkS-accredited wind energy assessment firm organized as a German limited partnership (Kommanditgesellschaft). Founded in 2016 with 11–50 employees, the company delivers accredited consulting services that quantify wind resource and energy yield potential for wind energy projects, with the primary deliverable being a TR6-compliant Windgutachten (wind assessment report) that satisfies bank financing ("bankability") requirements and EEG 2017 feed-in tariff calculations.

The company's service portfolio centers on five offerings: Windgutachten (TR6-compliant yield assessments), Standortgüte (site quality determination per EEG 2017), Referenzertrag (reference yield per TR5/TR6), Ertragseinschätzung (early-stage yield forecasting), and Datenanalysen (custom data analyses including repowering-oriented SCADA analysis). Underlying technology combines wind reanalysis time series, physics-based atmospheric interpretation (stratification, thermal effects), site-specific wind models, and integration of LIDAR, SODAR, and measurement mast data with operating SCADA data. All assessments comply with FGW e.V. Technical Guidelines TR5/TR6 and are delivered under DIN EN ISO/IEC 17025:2018 accreditation (D-PL-22504-01-00) with a flexible EA 2/15 scope, valid from 13.11.2024.

Commercially, 4cast operates a project-based professional services model with quote-based pricing (no public rates disclosed). The go-to-market is consultative, sales-led, and direct: prospective clients — primarily wind project developers, municipalities, private landowners, and banks/investors — engage via [email protected] or website contact forms. Standard processing time is up to 8 weeks per TR6 assessment, with prioritized processing available for transaction closings. The company supports engagements both domestically in Germany and internationally, supported by a bilingual German/English website. No external venture or private equity investors are disclosed; ownership appears founder/management-controlled through the general partner 4Cast Verwaltungs GmbH.

Revenue model

1. Wind Assessment (Windgutachten) Services: Project-based professional services delivering DAkkS-accredited, TR6-compliant wind energy yield assessments for wind farm financing. Revenue is generated per engagement/contract, likely as one-time professional service fees. The assessment is a prerequisite for bank financing, creating a non-optional purchase for project developers and investors.
2. Site Quality (Standortgüte) Determination: DAkkS-accredited site quality calculations per TR6 for EEG 2017 commissioning. Required by grid operators for feed-in tariff classification. Revenue is project-based, tied to new wind turbine commissioning cycles.
3. Reference Yield (Referenzertrag) Calculations: DAkkS-accredited reference yield calculations per TR5/TR6, used as the statutory denominator in EEG remuneration. Revenue is project-based per turbine type specification.
4. Yield Assessment (Ertragseinschätzung): Early-stage yield estimates for wind farm planning using wind reanalysis data. Supports strategic decision-making before costly wind measurements and permitting. Revenue is project-based.
5. Individualized Data Analysis Services: Custom data analyses for wind energy project planning, financing, or operational management. Revenue is per-engagement for bespoke analytical deliverables.

Core offering

4cast provides DAkkS-accredited wind energy assessments for project developers, municipalities, private landowners, and financial institutions. Its services include TR6-compliant Windgutachten (yield assessments), Standortgüte (site quality determinations for EEG 2017), Referenzertrag (reference yield calculations per TR5/TR6), Ertragseinschätzung (early-stage yield forecasting), and individualized Datenanalysen. All deliverables are based on physics-based meteorological interpretation integrating LiDAR, SoDAR, measurement mast, wind reanalysis, and SCADA operating data.

Product overview

4cast GmbH & Co. KG is a DAkkS-accredited consulting firm offering a suite of wind energy assessment services centered on TR6/TR5-compliant wind assessments. The core portfolio consists of Windgutachten (accredited yield assessments providing bankable energy data), Standortgüte (site quality certification for EEG 2017 compliance), and Referenzertrag (reference yield calculations as the statutory benchmark). These are complemented by Ertragseinschätzung (early-stage yield forecasting) and Datenanalysen (custom data analyses). All services follow FGW e.V. technical guidelines and are delivered as expert consulting reports, not software products.

Functional benefit

Products and services

• Windgutachten (Wind Assessment Report) TR6-compliant wind assessments providing accredited energy yield data for wind energy projects, based on wind measurement data (LiDAR, SoDAR, mast) and/or operational data. These reports ensure bankability for project financing and are intended for wind farm developers, banks, and investors.
• Standortgüte (Site Quality Determination) Site quality determination according to EEG 2017 before commissioning. Validates the compensation level for wind turbines by comparing site-specific yield to reference yield, providing documentation required by grid operators.
• Referenzertrag (Reference Yield Calculation) Reference yield calculation according to TR5 and TR6, providing the statutory benchmark for comparing wind turbine performance. Essential for EEG remuneration calculations and site quality determination.
• Ertragseinschätzung (Yield Assessment) Early-stage yield forecasting for wind farm planning, providing long-term average wind and yield potential estimates under relevant loss assumptions. Enables strategic decisions before costly wind measurements or permitting processes.
• Datenanalysen (Individualized Data Analyses) Individualized data analyses for wind energy projects, including operational data analysis, wind measurement data processing, and performance verification of existing wind turbines beyond standardized TR6 reports.

Quantifiable outcome

• Reduced uncertainty discounts: precise TR6 yield forecasts minimize the P75/P90 gap, maximizing project financing capacity
