Electric and magnetic fields

All electricity produces electric and magnetic fields (EMF) and our transmission lines are no different. Some people have concerns surrounding the perceived health effects of EMF exposure, and numerous studies have been undertaken internationally on the subject.

If you have concerns over EMF levels from one of our lines over your land, you may find the factsheets below useful. Alternatively you can contact us directly.
