Technical Due Diligence

ARTENG provides technical due diligence services to solar, wind and biomass projects for financial entities and sponsors.
This helps the stakeholders of the projects to identify and assess technical risks of the project.


We recommend technical due diligence study during 3 phases of the project depending on the project scale.

Pre-Construction Phase Technical Due Diligence in Solar & Wind & Biomass Projects

- Project site topography
- Project site geological situation
- Required permissions and approvals
- Zoning plan control
- Environmental impact assessment control
- Meteorological data assessment
- Feasibility study
- Module technical assessment
- PV Inverter technical assessment
- PV Module – Inverter compatibility
- Wind turbine technical assessment
- Checking wind farm micrositing
- Engine or turbine technical assessment of biomass plant
- Checking civil, mechanical and electrical design
- Assessment of contractors
- Checking warranties
- Energy yield study
- CAPEX assessment
- OPEX assessment
- Equity / Loan assessment
- Base case cash flow
- Base case environmental values

Construction Phase Technical Due Diligence in Wind Projects includes control and reporting of following activities / items

- Equipment’s’ arrival to the site
- Following the technical progress
- Controls related to the determined budget
- Controls related to the determined schedule baseline
- Information about any possible delays
- Controls related to determined scope baseline
- Check any installation process according to the contract / regulations / manuels

Construction Phase Technical Due Diligence in Solar Projects includes control and reporting of following activities / items

- Equipment’s’ arrival to the site
- Measurement of galvanization layer
- Installation of PV mounting structure
- Grounding and cable channels preparation
- Installation PV modules
- AC – DC cabling system
- Installation of site collecting board
- Check any installation process according to the contract / regulations / manuels

Operation Phase Technical Due Diligence in Wind and Solar Projects includes control and reporting of following activities / items

- Compare planned budget and actual budget, identify reasons if there is difference
- Compare planned and actual production values
- Compare planned and actual OPEX
- Compare predictions in the feasibility and actual values
- Define reasons if there is difference between planned and actual values
- Confirm the O&M contract being applied
