Minimising risk to protect your assets

Swire Renewable Energy provides electrical maintenance solutions to maximise the performance of the electrical components of the turbines and reduce the level of unplanned downtime.

Electrical maintenance solutions

Regular maintenance is the key to protecting electrical turbine components - enhancing safety, increasing production, minimising downtime and ultimately maximising your ROI. Regular maintenance can also ensure compliance to manufacturers warranties and reduce the risk of component failure.

Appointing a dedicated team committed to looking after your electrical components throughout their operational lifecycle can ensure you achieve these benefits and help deliver maximum generation during high wind periods.
