Electric and Magnetic Fields

Managing electric and magnetic fields

Electric and magnetic fields, commonly known as EMFs, occur naturally from lightning, solar activity and the earth itself. All living organisms produce EMFs. EMFs also exist wherever electricity flows. 

Our policy

We adopt a precautionary approach to the management of electric and magnetic fields by:

  • taking electric and magnetic fields into account in the design and location of new facilities
  • closely monitoring ongoing research and reviews by scientific panels and international policy developments
  • regularly reviewing our policies and practices in light of the latest scientific information
  • measuring field strengths in and around our own installations and other places where appropriate
  • providing up-to-date information to interested people on request.

Our EMF Fact Sheet provides general information on electric and magnetic fields in relation to our network as well as resources for further information.
