1. As at 31 March 2005, the total length of underground powerlines in WA was 12,601 kilometres. As at 31 March 2005, the total length of metropolitan underground powerlines was 9794 km. 2. As at 30 June 2004, the total length of overhead powerlines in kilometres in WA was 74,067 kilometres. As at 31 March 2005, the total length of metropolitan overhead powerlines was 13,044 km. 1. Western Power's policy is to install all new powerlines in urban areas underground. All new residential, commercial and industrial subdivisions require underground reticulation. All new powerlines installed to meet natural load growth in urban areas are installed underground. Some rural powerlines are installed overhead due to the large distances involved and the cost associated with undergrounding these powerlines. Total project costs are recorded for the above-mentioned underground works. Costs associated with installation of the powerlines alone for the above underground works is not clearly identifiable as total project costs include land acquisition, installation of ground mounted transformers and switchgear, removal of existing overhead assets, Western Power has a retrospective undergrounding program whose sole purpose is to underground existing overhead assets. This is funded 25% State Government, 25% Western Power and 50% local government. The following figures relate to the total cost of underground powerline installation through the State Underground Power Program. (a) 1996-1997 $8.95M (b) 1997-1998 $8.80M (c) 1998-1999 $7.69M (d) 1999-2000 $18.41M (e) 2000-2001 $29.68M (f) 2001-2002 $22.67M (g) 2002-2003 $18.59M (h) 2003-2004 $9.99M* (i) 2004-2005 $22.47M (j) 2005-2006 $29.13M (k) 2006-2007 $25.75M (l) 2007-2008 $24.51M (m) 2008-2009 $22.01M * Expenditure was reduced during 2003/04 while improvements were made to the way designs and cost estimates were carried out before starting projects. (4) Total kilometres of Western Power powerlines installed underground in the South West Interconnected System during the years requested is shown below. Note that this does not include transmission lines (ie. voltage levels of 66 kV and above). As of June 2004, 33 km of transmission lines were underground. (a) 1996-1997; 503 km (b) 1997-1998; 505 km (c) 1998-1999; 689 km (d) 1999-2000; 1076 km (e) 2000-2001; 974 km (f) 2001-2002; 978 km (g) 2002-2003; 434 km (h) 2003-2004; and 1088 km (i) 2004-2005 to date 652 km to March 05 (5) Western Power does not plan expenditure on the basis of undergrounding a target distance of overhead power lines, so no estimates for the scheduled length of cable installed underground by Western Power is available. Expenditure on the Western Power network is driven by reliability, load growth and customer initiated projects. Meeting these requirements may involve a combination of new underground powerlines or upgraded overhead powerlines based on the best safety, technical and economic solution. Despite not planning explicitly for underground powerline installation, present work levels indicate that for the next 3 years approximately 1000km per year of new underground powerlines will be installed.

1. As at 31 March 2005, the total length of underground powerlines in WA was 12,601 kilometres. As at 31 March 2005, the total length of metropolitan underground powerlines was 9794 km. 2. As at 30 June 2004, the total length of overhead powerlines in kilometres in WA was 74,067 kilometres. As at 31 March 2005, the total length of metropolitan overhead powerlines was 13,044 km. 1. Western Power's policy is to install all new powerlines in urban areas underground. All new residential, commercial and industrial subdivisions require underground reticulation. All new powerlines installed to meet natural load growth in urban areas are installed underground. Some rural powerlines are installed overhead due to the large distances involved and the cost associated with undergrounding these powerlines. Total project costs are recorded for the above-mentioned underground works. Costs associated with installation of the powerlines alone for the above underground works is not clearly identifiable as total project costs include land acquisition, installation of ground mounted transformers and switchgear, removal of existing overhead assets, Western Power has a retrospective undergrounding program whose sole purpose is to underground existing overhead assets. This is funded 25% State Government, 25% Western Power and 50% local government. The following figures relate to the total cost of underground powerline installation through the State Underground Power Program. (a) 1996-1997 $8.95M (b) 1997-1998 $8.80M (c) 1998-1999 $7.69M (d) 1999-2000 $18.41M (e) 2000-2001 $29.68M (f) 2001-2002 $22.67M (g) 2002-2003 $18.59M (h) 2003-2004 $9.99M* (i) 2004-2005 $22.47M (j) 2005-2006 $29.13M (k) 2006-2007 $25.75M (l) 2007-2008 $24.51M (m) 2008-2009 $22.01M * Expenditure was reduced during 2003/04 while improvements were made to the way designs and cost estimates were carried out before starting projects. (4) Total kilometres of Western Power powerlines installed underground in the South West Interconnected System during the years requested is shown below. Note that this does not include transmission lines (ie. voltage levels of 66 kV and above). As of June 2004, 33 km of transmission lines were underground.

Expenditure on the Western Power network is driven by reliability, load growth and customer initiated projects. Meeting these requirements may involve a combination of new underground powerlines or upgraded overhead powerlines based on the best safety, technical and economic solution. Despite not planning explicitly for underground powerline installation, present work levels indicate that for the next 3 years approximately 1000km per year of new underground powerlines will be installed.

Note that this does not include transmission lines (ie. voltage levels of 66 kV and above). As of June 2004, 33 km of transmission lines were underground. (a) 1996-1997; 503 km (b) 1997-1998; 505 km (c) 1998-1999; 689 km (d) 1999-2000; 1076 km (e) 2000-2001; 974 km (f) 2001-2002; 978 km (g) 2002-2003; 434 km (h) 2003-2004; and 1088 km (i) 2004-2005 to date 652 km to March 05 (5) Western Power does not plan expenditure on the basis of undergrounding a target distance of overhead power lines, so no estimates for the scheduled length of cable installed underground by Western Power is available. Expenditure on the Western Power network is driven by reliability, load growth and customer initiated projects. Meeting these requirements may involve a combination of new underground powerlines or upgraded overhead powerlines based on the best safety, technical and economic solution. Despite not planning explicitly for underground powerline installation, present work levels indicate that for the next 3 years approximately 1000km per year of new underground powerlines will be installed.
