Wind Farms Inspections
Wind Farms surveillance can be divided into 2 main categories in terms of the customer profile it addresses.
Surveillance of Project Developers and Owners: Generally, wind farm project developers and owners are private organizations that will carry out the projects in the medium and long term. Therefore, the planning and construction phase of projects is very important for Project feasibility analysis. For this reason, the following services are important:
Planning and making wind measurements
Decisive Study / Meso mapping
Investigation of meteorological field conditions
Measuring Pole Supply and Installation
Statistical analysis of wind measurements
Evaluation of wind potential and energy efficiency
Wind Services for Project Financiers and Lenders (eg Banks): Most wind projects are developed through a financing mechanism regardless of the financing model. Projects always have some of the capital, but most generally more than half of the investment comes from Banks, Funds etc. It is funded by Credit Institutions such as Therefore, the Project feature under review plays a key role for financing partners of wind projects.

Solar Power Plants Inspections
Solar (Photovoltaic) plant inspections review the entire plant design to ensure functionality and reduce risks, by reviewing standards and contracts, based on extensive experience. Solar (Photovoltaic) plant surveillance can be grouped in 5 different phases:
Planning phase: This phase usually includes on-site inspections, shading analysis, energy yield estimation and evaluation, IRR analysis, loss analysis, and feasibility report evaluations before the investment begins.
Design phase: The design phase includes manufacturer and on-site PV module inspection, certification of PV modules through accredited laboratories, preliminary inspection and loading inspection for PV modules, supplier evaluations, environmental inspections, standards compliance inspection, and subcontractor evaluations.
Construction phase: Quality Assurance inspections and Quality Control inspections during construction and assembly play a key role in the Quality and Safety of PV projects. Production surveillance, compliance checks, fault detection in the early stages of construction, participation in Factory Acceptance Tests and field tests of critical components such as Inverters, Transformers should be performed.
Operation and Maintenance: It covers device fault detection and analysis, DC breakdown test, on-site inverter evaluation, Infrared camera controls, Operation and Maintenance evaluation process.
Monitoring: For Lenders and Financiers of PV plant projects, Technical Due Diligence and Project Monitoring services play a key role in assessing the feasibility of the Project. During the first report preparation period, energy efficiency assessments will be made by energy experts. Periodic monitoring reports and final closing reporting are also made by PV experts.
Hydraulic Plant Inspections
HPP inspections are generally more construction-oriented projects due to the nature of hydropower plants. Services can be classified in 3 stages:
Project initiation and design phase: Project management, project monitoring and project financing / budgeting, Due diligence, Procurement and implementation support, Feasibility studies and location studies, Site survey: Topography and cartography, geotechnical studies, protected areas interference analysis, archaeological sites examination .
Construction and Commissioning phase: Owner’s engineering services: Budget, schedule and quality control, geotechnical reports, Review and approval of design changes, Review of technical specifications and procurement planning. Approval and follow-up of the control points program in factory inspections, Daily supervision of construction works, follow-up of necessary machinery and personnel, Health, safety and environmental management (HSE), Supervision of contractors’ quality control plan
