Wind Turbines

Wind Turbines are now a familiar sight across the UK, powering homes, businesses, and communities with clean, renewable energy. But behind every spinning blade is a complex network of electronic systems that work around the clock in harsh conditions. Like any machine operating 24/7, wear and tear is unavoidable – and when electronic components fail, the cost of replacement can be extremely high.

At Greasley Electronics, we are proud to be one of the UK’s leading specialists in the refurbishment and repair of industrial circuit boards, including those used in wind turbines. Our work helps wind farm operators dramatically reduce costs, avoid unnecessary downtime, and extend the life of critical systems.

Why Wind Turbine Electronics Fail

Wind Turbines operate in demanding environments – exposed to temperature extremes, vibration, moisture, and continuous electrical load. Over time, this stress causes components to degrade.

Wind Turbine Failures – One of the most common faults we see is capacitor failure. Capacitors gradually dry out due to heat, which can lead to unstable power supplies and complete PCB failure. When this happens, many operators are told the only option is a full replacement – often costing thousands of pounds and involving long lead times. Replacement capacitors can be hard to find but we stock some of them or can get them reasonably quickly.

However, in many cases, repair and refurbishment is not only possible, but far more cost-effective.

Real Repairs, Real Savings

This week alone, we received three wind turbine circuit boards from a company in Scotland. Each had power supply faults caused by aged components. Rather than replacing the boards, our engineers were able to assess, repair, and refurbish them – saving the customer thousands of pounds and getting their systems back online quickly.

This is a common story across the industry:

• Replacement boards are expensive
• Lead times can be long
• Downtime costs add up fast

Repairing instead of replacing can cut costs dramatically while keeping turbines operational.

The Value of Preventative Maintenance

Many failures could be avoided with a planned electronic maintenance programme. By inspecting and refurbishing PCB’s every few years, worn components can be replaced before they cause system failure. This proactive approach:

• Reduces unplanned downtime
• Extends the life of equipment
• Saves money on emergency replacements
• Improves system reliability

Refurbishment is not just a repair – it’s an investment in long-term performance.

Supporting the UK Wind Industry

We take great pride in supporting wind farm and turbine operators across the UK by providing reliable, and cost-effective electronic repairs. Our expert team understands the importance of keeping renewable energy systems running smoothly and efficiently.

If you have wind turbine faults electronic faults – or if you’d like to explore a preventative refurbishment plan – we’re here to help.
