Before or after the investment decision, we independently assess the technical condition of wind and solar power plants.
The physical condition of the site, its compliance with the relevant regulations and the readiness level of the electrical infrastructure are reviewed independently. Site access, road infrastructure and the condition of the grid connection point are also included in this assessment.
The wind resource and yield calculations used in the project are reviewed independently, and the assumptions and methodology are verified. The quality and representativeness of the measurement data used are also examined.
A general condition assessment is made by examining the turbines' physical condition, maintenance history and performance data. Possible signs of wear in critical components such as blades, gearbox and generator are observed on site.
Supply, warranty and operation-maintenance contracts are evaluated from a technical perspective to identify risky clauses. The adequacy of performance guarantees and penalty conditions in the investor's favour is examined.
The technical specifications and design suitability of the turbine, substation and grid connection components are examined. The suitability of the equipment used for site conditions and the relevant standards is evaluated.
For projects under construction, cost outturn and physical progress are reported by comparison with the planned schedule. Risks of possible delays and cost overruns are flagged at an early stage.
The physical condition of the site, its compliance with the relevant regulations and the readiness level of the electrical infrastructure are reviewed independently. For ground-mounted projects the ground conditions, and for rooftop projects the suitability of the mounting structure, are assessed separately.
The solar resource data and production forecasts used in the project are reviewed independently. The realism of the simulation assumptions used (shading, loss rates, etc.) is questioned.
The physical condition, performance data and possible degradation effects of panels and inverters are evaluated. Common problems such as hot-spot formation and junction box failures are checked on site.
The relevant supply, warranty and operation-maintenance contracts are evaluated from a technical perspective. The adequacy of panel performance warranties and inverter warranty periods is also examined.
Technical elements such as system design, cabling and inverter placement are reviewed to assess suitability. It is checked whether parameters such as the DC/AC ratio and string design have been optimally selected.
For projects under construction, cost outturn and physical progress are reported by comparison with the planned schedule. We aim to detect supply delays and site execution errors at an early stage.
