DISCLOSURE OF OPTIMAL DEPRIVAL VALUE (ODV) PURSUANT TO REGULATION 19 OF THE ELECTRICITY INFORMATION DISCLOSURE REGULATIONS 2004

ODV as per latest valuation:

2005 2004 2003 2002
$905,101,595 $905,537,817 $703,286,496 $377,155,971

Disclosure of Energy Delivery Efficiency Performance Measures and Statistics Pursuant to Electricity Information Disclosure Amendment Requirements 2004, Schedule 1, Part 4, Requirement 20.

20.1 ENERGY DELIVERY EFFICIENCY PERFORMANCE MEASURES

(a) Load Factor

Year Powerco
2005 67.4%
2004 67.2%
2003 71.7%
2002 65.9%

(b) Loss Ratio

Year Powerco
2005 5.58%
2004 6.82%
2003 6.57%
2002 5.86%

(c) Capacity Utilisation

Year Powerco
2005 27.5%
2004 28.8%
2003 25.7%
2002 29.44%

Note:

20.1 (a): 2003 load factor is calculated using the time weighted average method. The load factor calculated using full year actual data is 66.5%.
20.1 (d): 2003 loss ratio is calculated using full year kWh data for Western area, and 5 month (Nov 2002 to Mar 03) kWh data for Eastern area.
It is a time weighted calculation based on actual data.
20.1 (b): Loss ratios depend on information gathered from retailers.
20.1 (c): 2003 capacity utilisation is calculated using the time weighted average method. The capacity utilisation calculated using full-year actual data is 28%.

(c) Underground Line Length

Nominal Voltage 2005 (Powerco UG Line Length (km)) 2004 (Powerco UG Line Length (km)) 2003 (Powerco UG Line Length (km)) 2002 (Powerco UG Line Length (km))
110kV - - - -
66kV 1.00 0.08 0.03 -
33kV 92.80 101.59 31.67 45.96
22kV 0.43 0.36 0.35 0.33
11kV 1,763.22 1,682.79 1,531.22 1,672.25
6.6kV 195.42 196.85 189.68 191.87
