Project Background

What?

The Ginninderry Joint Venture is preparing to submit a Development Application to the ACT Government regarding the alignment of the Upper Tumut (Line 7) and Lower Tumut (Line 1) 330 kilovolt (kV) transmission lines. Ginninderry’s proposal is to:

  • decommission and remove part of the Upper Tumut (Line 1) and Lower Tumut (Line 7) transmission lines;
  • divert transmission lines from near the ACT/NSW border and extend southeast, crossing the Molonglo and Murrumbidgee Rivers in the ACT and then connecting to existing towers at the Stockdill Substation on Stockdill Drive in Belconnen, ACT; and
  • string an extension line (Line 3C) onto existing towers running between the Canberra and Stockdill Substations along the edge of the suburb of Holt. This additional line would be a continuation of the new Lower Tumut transmission line as it runs past the Stockdill Substation, continuing to the Canberra Substation.

Why?

  • Increase availability of housing in the ACT, including affordable housing
  • Conservation outcomes and visual amenity would be improved in the Ginninderry Conservation Corridor
  • Removal of the lines near Ginninderry would improve local amenity by reducing visual impacts on residential areas
