// IN SHORT

Short answer: GWO's Entry Level Wind Technician Framework is the industry's agreed checklist for new wind techs. It defines three entry-level job profiles (pre-assembly, installation and service) and the training for each. Everyone needs GWO BST (First Aid, Manual Handling, Fire Awareness, Working at Heights) plus BTT Mechanical, then extra modules depending on the job. A full entry-level profile takes 8 to 20 training days.

The framework comes from the Global Wind Organisation (GWO), agreed by its members, the largest employers in wind. Here are the most important parts, in plain words.

GWO members, the largest employers in wind, agreed on it together. It describes what a beginner wind tech should know, what they should be able to do, and which GWO trainings they need for each type of job.

Here are the most important parts, in plain words.

Why This Framework Matters to You

The framework was made for two groups of people:

  • People starting out, and the schools and colleges training them.
  • People moving from other industries, so their existing skills can be recognised.

If you belong to either group, this is the closest thing the industry has to an official "how to become a wind tech" checklist. Training to this framework means you arrive with the trainings employers have already agreed they want.

What Is a Wind Technician, According to GWO?

GWO uses "wind technician" as a broad term. It covers people who assemble, install, inspect, service, maintain and repair wind turbines.

As a beginner, you'll always work alongside more experienced technicians. Some new techs build new turbines: towers, nacelles, hubs, blades and electrical systems. Others go into service and maintenance: replacing worn or faulty parts and repairing systems.

Whatever the job, one rule never changes: you follow the manuals, procedures and bulletins. Always.

GWO is also honest about the conditions:

  • Wind farms are often remote, onshore and offshore.
  • You'll work in heat, cold and bad weather, often far from home for long periods.
  • You'll climb ladders to the nacelle, often 80 metres or higher, carrying tools.
  • You'll work in tight spaces and at height.

That's why GWO says plainly that physical fitness is vital for this job.

The Skills Employers Expect

The framework groups the expected skills into three levels.

General abilities

  • Meet your employer's fitness-for-duty requirements
  • Attention to detail
  • Read basic system diagrams, schematics and symbols
  • Teamwork
  • Mechanical and/or electrical fundamentals
  • Basic computer, software and mobile device skills
  • Comfort working in small spaces and at height

What you must do yourself

  • Climb to the nacelle with tools and equipment, and keep working without tiring quickly
  • Lift heavy parts, tools and equipment
  • Follow all health, safety and operating procedures
  • Take part in daily task planning
  • Write clear reports on inspections, repairs and problems you find, and keep service logs
  • Follow written procedures and equipment manuals
  • Use your PPE correctly: harness, helmet, glasses, gloves, safety shoes, high-vis
  • Understand how weather affects safety
  • Perform rescue in an emergency

Don't skip the reports part. Many beginners think the job is only about spanners. Clear, organised reports are a written requirement.

What you'll help experienced techs with

Under supervision of a skilled technician or a Qualified Electrical Worker, you'll assist with:

  • Scheduled and unscheduled mechanical, electrical and hydraulic maintenance
  • Hoisting and rigging
  • Troubleshooting, sampling and measuring
  • Replacing major components like generators and gearboxes
  • Finding faults and fixing them
  • Testing systems after maintenance and outages

Three Entry-Level Job Profiles

GWO splits entry-level technicians into three profiles. Each matches one part of the wind turbine's life.

1. Pre-Assembly Technician

You prepare components before they go up: assembling tower sections, installing and terminating cables inside the tower, installing turning gear, preparing control systems, and getting the nacelle, tower and blades ready for installation.

2. Installation Technician

You build the turbine itself: loading and unloading, installing mechanical and electrical systems, working on bolted connections, inspecting welds, and preparing the turbine for commissioning. Onshore or offshore.

👉 More about this role: Wind Turbine Installation: From Ground to Grid

3. Service Technician (O&M)

You do planned and unplanned maintenance, replace parts, keep detailed records of all work and parts used, and report safety issues to site management.

One important limit from the framework: as an entry-level service tech, you don't work inside electrical cabinets or on controllers without direct supervision by a qualified electrical technician.

The Training: Three Layers

GWO divides the training for every profile into three layers.

  1. Core training: everyone needs it, whatever the job.
  2. Profile and task-specific training: depends on the profile, the exact tasks and the location (onshore or offshore).
  3. Company and region-specific training: given by your employer after you're hired.

In total, an entry-level profile takes between 8 and 20 training days, depending mostly on the task-specific part.

Layer 1: Core training (all profiles)

  • GWO BST: First Aid, Manual Handling, Fire Awareness, Working at Heights
  • GWO BTT: Mechanical

Layer 2: By profile

Training Pre-Assembly Installation Service
BTT Bolt Tightening ✔ ✔ ✔
BTT Installation ✔ ✔
BTT Electrical ✔ ✔
BTT Hydraulic ✔
Crane and Hoist (Basic User, Inspection & Maintenance) ✔ ✔
Control of Hazardous Energy (CoHE) Basic ✔ ✔

Depending on the job and location, for any profile:

  • BST Sea Survival: if you work offshore
  • Slinger Signaller: if you take part in crane lifts
  • Advanced Rescue Training (ART): rescue in the hub, blade, nacelle, tower and basement
  • Lift User: if the turbine has a service lift
  • Enhanced First Aid (EFA): for remote sites

Layer 3: Company training

After hiring, expect your employer's own courses. Common ones are site safety rules, documentation, safe systems of work, hand tool awareness, climb assist, confined space and turbine familiarisation.

Take Your Courses in the Right Order

Some GWO trainings need others first:

  • Before any GWO course: register your WINDA ID and be medically fit to take full part.
  • BTT Bolt Tightening: you need BTT Mechanical first.
  • BTT Installation: you need BTT Mechanical and Bolt Tightening first.
  • ART: you need valid BST Working at Heights, Manual Handling and First Aid.

A centre will turn you away if you don't have the prerequisites, so plan your bookings in this order.

Which Certificates Expire?

Training Valid for
BST (all modules) 24 months, then a refresher
Advanced Rescue Training 24 months
Enhanced First Aid 24 months
Control of Hazardous Energy 24 months
BTT (all modules) No expiry
Slinger Signaller No expiry
Lift No expiry
Crane and Hoist No expiry

Local rules can be stricter. Germany, for example, requires Working at Heights every 12 months.

BTT Doesn't Make You a Qualified Tech

The framework is very clear about this: BTT lets you do basic mechanical, electrical and hydraulic tasks under the supervision of an experienced technician. It does not make you qualified to do that work on your own.

The same goes for Control of Hazardous Energy. It gives you a common base, but your authorisation to work on hazardous energy comes from your employer's own training and procedures.

GWO trainings get you through the door. Experience and company training make you a technician.

Coming from Another Industry?

GWO says wind employers recognise skills from similar industries, including:

  • Marine
  • Mining
  • Military
  • Electrical substations
  • Oil and gas
  • Chemical, industrial and power plants

If you've worked in any of these, put it clearly on your CV. Employers can also use GWO's merit system: they compare your earlier training with the GWO standards and can recognise part of it, so you don't repeat everything from zero.

Where It Can Lead

With experience and more training, the framework lists roles you can grow into: lead technician (installation or service), commissioning technician, troubleshooter, high-voltage specialist and site supervisor.

A skilled technician knows every system of the turbine: structural, mechanical, electrical, controls, communications, hydraulics and braking. That's the long-term goal. The entry-level framework is the first step on that road.
