Ausgrid have assured residents that there are no plans to expand its substation site at Hamilton South.

Residents had raised concerns over the potential expansion plans after four people died of cancer in the nieghbourhood in the space of five years.

Ausgrid maintain reports that they were planning on expanding the Glebe Road station are unfounded.

The company has also made moves to allay public upheaval about electromagnetic field readings it took last week.

Concerned residents are urged to contact Population Health.
