3 Wind Measurement (WM) During the development of a wind farm, we guide our customers in setting up a measurement strategy that minimises uncertainty, including: Choice of measurement location and type (mast/remote sensor) LiDAR verification against a met mast prior to its on-site installation Specification for the mast set-up to IEC On-site validation of the measurement installation and reporting Measurement campaign follow-up: daily download, weekly check, monthly reporting to optimise data availability and consistency Additional services include the supply of calibrated and tested instrumentation systems as well as rental LiDAR systems. Energy Yield Assessment (EYA) DEWI offers comprehensive EYA service, from large-scale wind potential determination using Mesoscale modelling to accurate assessment of the site conditions, including calculation of the expected energy yield at specific wind farms at pre-/post construction stage. The suitability of the planned wind turbine type to the site characteristics and correspondence to the IEC norm is checked via DEWI s site classification assessment. Pre-Construction Stage Post-Construction Stage Site Inspection Wind data analysis from mast and Production data analysis from SCADA remote sensors (SODAR/LiDAR) data or monthly operational data Long-term correction of the on-site available data Wind flow modelling (WASP/CFD) Wind farm efficiency calculation Calculation of the expected energy yield (gross p50) under consideration of systematical losses (net p50) and the respective uncertainties and exceedance probabilities (p75, p90, p99 values) Wind Measurements (WM) Validation of Mast Installation WM Campaign Follow-up Energy Yield Assessment (EYA) Pre- Construction EYA Postconstruction EYA (minimum 1 year of operation) Technical Due Diligence (DD) Pre-financing Due Diligence Construction Follow-Up Operational Follow-Up Turbine Inspections before take-over Periodic / End of Warranty Inspections Wind Farm Performance Analysis Power Curve Verification (PCV) Site Assessment Site Calibration Power Curve Measurement Development Phase Construction Phase Operation Phase Contract Negotiation Financial Close Take-Over of the Wind Farm Power Curve Verification (PCV) DEWI offers the entire range of wind turbine power curve verification services to ensure the equipment s performance meets IEC and MEASNET procedures: Site assessment to determine site complexity (site calibration required or not) and define the test details including mast location. (Note: early assessment ensures technical adequacy to the specific site) Warranty check to analyse the contractual conditions for PCV Site calibration for complex sites after financial close PCV according to the current standard Alternative methods of assessing power curves using ground- or nacelle-based LiDAR are also offered by DEWI. Please note: All services are available as a complete package or individually. Due Diligence (DD) Pre-Financing & Acquisition Services In the course of financing or acquiring wind farms, our experts review project documentation from a technical perspective in order to identify risks: Wind resources: third-party energy yield assessment Documentary specifications: review of permits & contracts for construction phase and later operations Technical specifications: turbine technology review, electrical & civil works design, construction schedule etc. Finance specifications: cash-flow reviews (OPEX/CAPEX) DD Construction Follow-Up During the construction phase, our experts follow up on work at the site to identify deviations from the planned construction and investment schedule. DD Operational Follow-Up During the operation phase, we perform technical inspections to assess wind farm performance (e.g. production, availability, and reasons for downtime), as well as current conditions.

4 Services for Wind Farm Stakeholders Our Wind Farm & Energy Project Expertise Understanding the risks and uncertainties related to wind farm projects is essential to ensuring reliable planning and efficient operation. Since wind farms are a substantial investment, the earlier that risk assessment of key milestones takes place, the easier it will be to avoid undesirable later developments, saving considerable costs long-term. DEWI helps stakeholders developers, investors and operators to identify the critical aspects related to wind farm projects through comprehensive one-stop services, individually tailored and flexibly delivered. Anemometer Calibration Calibrated anemometers are essential for accurate wind speed and power curve measurements, and each one must be individually calibrated prior to a measurement campaign. As an accredited service, DEWI offers calibration to the MEASNET standard. Wind vane testing is also advisable, and can be performed by our experts. LiDAR Verification Prior to measuring with a remote sensing device on a site without a measurement mast, the IEC requires that the LiDAR is verified against a high-quality measurement mast of suitable height equipped with calibrated cup anemometers. DEWI offers this service, providing traceability of the wind speed and wind direction signal. Additional Services Site Classification according to IEC including turbulence analysis Acoustical noise emission measurement of wind turbines according to IEC Noise estimation Estimation of shadow flicker Project-specific loss determination relative to: icing, electrical design as well as curtailment aspects (acoustical, bats, sector management, etc.) National & International Committees DEWI is recognised by national and international committees as a key participant in defining wind energy standards, such as: IEC International Electrotechnical Commission IEA International Energy Agency CENELEC Comité Européen de Normalisation Électrotechnique MEASNET DKE Deutsche Kommission Elektrotechnik Elektronik-Informationstechnik in DIN und VDE Technical Guidelines for Wind Turbines (guidelines published by FGW, Germany) What sets DEWI apart?
