TL;DR:

  • UK and European wind energy operators are deploying VR training for offshore turbine technicians, covering height safety, emergency descent, and blade inspection procedures at a fraction of the cost of on-site training
  • Solar installation companies are piloting AR guidance systems that overlay wiring diagrams and torque values directly onto the physical installation, reducing errors by new technicians
  • As the UK’s renewable energy workforce needs to grow significantly to hit 2030 targets, XR-based training is becoming a mainstream pipeline for new entrants without prior electrical experience

The renewable energy sector has a skills problem. The UK needs roughly 400,000 additional workers by 2030 to build and maintain the solar, wind, and heat pump infrastructure required under the clean energy plan. Traditional apprenticeships can take 3-5 years. The maths doesn’t work at existing training throughput.

XR — virtual and augmented reality — isn’t solving this entirely. But it’s compressing early training timelines meaningfully, improving safety outcomes for inexperienced technicians, and making some training scenarios possible that simply weren’t feasible before.

VR for Offshore Wind Technician Training

Offshore wind turbine technician is one of the most dangerous entry-level roles in any industry. Technicians work at heights of 80-150 metres on structures offshore, often in poor weather, accessing via helicopter or vessel. Training someone to work safely in that environment traditionally means extensive on-site time — either at decommissioned turbines used for training or during supervised offshore shifts, neither of which scale easily.

VR changes the practicalities. The training scenarios that have been transferred to virtual environments first are not incidentally the most expensive to conduct in real life:

Emergency descent training. If a fire breaks out inside a nacelle at 80 metres, a technician needs to know how to use an emergency descent device — essentially a controlled rappel down the tower. In real life, you can practise this a limited number of times before the cost and disruption (and wear on the equipment) become prohibitive. In VR, you can run the scenario 20 times in a morning with variations: different weather, different failure scenarios, reduced visibility from smoke simulation.

Height acclimatisation. Many people experience acrophobia or height-related anxiety that only becomes apparent at altitude. Running candidates through VR height exposure before they reach a real tower identifies those who need additional support earlier, preventing safety incidents during real offshore work. Ørsted and Vestas have both piloted VR height acclimatisation modules.

Blade and component inspection procedures. Large turbine manufacturers provide VR modules that mirror the internal service procedures for specific turbine models — following the exact maintenance sequence, identifying common fault signatures, practising the hand positions for bolt torquing in a confined nacelle. Siemens Gamesa’s SG Learning platform includes VR modules for their SG 5.0 and SG 11.0 series.

Platform: most deployments use Meta Quest 3 or Pico 4 Ultra. Standalone headsets are preferred for training centres because they don’t require workstation PCs per trainee. HP’s Omnicept was used in some early wind training deployments but the market has consolidated toward Quest/Pico for cost reasons. The scenarios are built in Unity with VR physics that simulate wind loading, vibration, and the physical resistance of torque tools.

AR for Solar Installation

Solar photovoltaic installation is lower-hazard than offshore wind but still requires precise electrical knowledge: correct string sizing, overcurrent protection, earthing systems, safe disconnect procedures. Errors by undertrained installers are a significant cause of substandard installations that either perform poorly or create safety risks.

AR overlay systems are being piloted to guide new installers through procedures in real time:

Wiring overlay guidance. A technician wearing AR glasses (currently most deployments use HoloLens 2 or Vuzix Blade 2 in industrial settings, or smartphone-based AR via a tablet stand-mount on the inverter cabinet) sees wiring diagrams overlaid on the physical components. Rather than cross-referencing a paper manual with the actual inverter, the AR system highlights the specific terminals and shows the cable route with a colour-coded overlay that matches the physical cable colours.

Torque value prompts. Solar inverter and DC isolator bolted connections have specific torque requirements — under-torqued connections create resistance and fire risk; over-torqued connections can strip threads. AR systems display the correct torque value for each fastener type alongside the connection point, triggered by the technician’s gaze or a manual tap to confirm each step.

System performance review. Some AR deployments integrate with inverter monitoring APIs so a technician reviewing an existing installation sees live performance data (current generation, string voltage, fault codes) overlaid on the physical hardware without needing to read a separate phone app.

UK companies currently deploying solar installation AR include a consortium of MCS-accredited installers working with the Net Zero Innovation Portfolio (NZIP) funded Digital Energy Skills programme, and several of the larger solar installation companies running internal installer training.

The Economics of XR vs. Traditional Training

The business case for XR training in renewables is primarily about throughput and safety incident reduction:

Cost comparison for offshore wind technician basic safety training:

  • Traditional on-site programme (boat, tower time, instructor): £3,000-5,000 per trainee
  • VR + classroom hybrid (same safety certification outcomes): £400-800 per trainee

The VR module cost (headset + software licence) is paid once; the marginal cost per additional trainee is near zero once the hardware is amortised.

Throughput: A single training centre with 10 VR headsets can run the same safety scenario in parallel for 10 trainees simultaneously, with an instructor monitoring from a facilitator view. The same instructor ratio in a real on-site setting handles 3-4 trainees at most.

The human limitation: VR training does not replace hands-on practice with physical tools. Bolt torquing, wire termination, cable management — these require physical practice on real equipment. The most effective programmes use VR for the safety, procedural, and decision-making components, then transition trainees to physical rigs for tool skills.

What’s Coming

The next capability being piloted is AI-driven adaptive scenarios that adjust difficulty based on performance within the VR environment — a trainee who demonstrates confident emergency descent procedure gets a more complex scenario with unexpected complications, while a trainee struggling with the standard sequence repeats and receives additional guidance.

For solar AR, the integration direction is towards real-time roof structural analysis using LiDAR scanning on iPads to generate optimised panel layout recommendations before a single fixing goes in.

The renewable energy skills gap is real and the 2030 timeline is not generous. XR training is not a complete solution but it’s one of the few tools that can meaningfully compress the training-to-deployment timeline for the new workforce the energy transition requires.
