Wind turbine commissioning
We verify compliance with design documentation and commission the turbine per OEM requirements and applicable technical standards.
Commissioning (COD) completes construction and installation. It verifies that civil and mechanical work meets the design, detects defects in process equipment and control systems, and brings the WTG into service per OEM requirements and standards.
Typical commissioning scope includes:
- Preparation and commissioning plan.
The plan typically covers:
- sequence of commissioning activities;
- schedule and milestones;
- PPE and tools list — equipment must be calibrated and compliant with safety standards;
- staffing with valid certifications and site access;
- safety briefing and site work organisation.
After approval to proceed, we verify that grid parameters meet design and applicable standards.
- Energisation (nominal voltage) to verify automation, protection, and control. Deviations are corrected per OEM procedures.
- Commissioning of auxiliary systems, control, and safety; run the WTG in generation across operating conditions. Sufficient wind is required to test multiple operating modes.
- Relay protection, telecontrol, and metering aligned with grid codes and technical conditions; verify data exchange with the grid operator.
- Integrated testing with balance-of-plant to confirm performance.
Commissioning is documented for regulatory acceptance and commercial operation. Successful COD confirms installation quality, safe operation, and reliable performance of all systems.
We provide commissioning across Belarus, Kazakhstan, and Russia. Call +375 (29) 747-07-09 (+7 (967) 351-67-68), email info@ecotek.pro, or use the contact form.
FAQ — wind turbine commissioning
It includes grid or temporary generator connection, energisation of mechanical and electrical systems, testing, and tuning of all WTG subsystems.
Typical stages:
- Preparation and commissioning plan (may require authority approval).
- Internal electrical and auxiliary connections; assembly of major turbine assemblies.
- Grid or temporary generator energisation; nominal voltage test.
- Control and monitoring setup.
- Required tests and trials.
- Permits and certificates as applicable.
Commissioning can involve first energisation and assembly issues — electrical safety, work at height, and competent personnel on site are critical.
Use only calibrated tools with valid certificates.
A detailed plan, clear coordination between customer and contractor, and experienced teams with spare parts on site reduce downtime and risk.
Tests include electrical checks (loop impedance, lightning protection, grounding, insulation, electrical measurements), noise where required, and OEM-specific tests such as pitch, yaw, converter performance, and power curve checks.
After testing, equipment is accepted with formal records and laboratory reports, enabling handover to the grid operator per local regulations.
