Disclosure of energy delivery efficiency performance measures under requirement 20 of the Electricity (Information Disclosure) Requirements 2004 Schedule 1 Part 4.

1 Energy Delivery efficiency performance measures:

(a) Load factor (=a/bc100)

2004 2003 2002 2001
a = kWh of electricity entering system 207,165,465 211,261,285 197,992,332 201,936,757
b = Maximum demand 36,024 38,232 35,650 34,776
c = Total number of hours in year 8,760 8,760 8,760 8,760
Load factor % 65.6% 63.1% 63.4% 66.3%

(b) Loss ratio (=(a/b)*100)

2004 2003 2002 2001
a = losses in electricity in kWh 14,434,000 9,603,837 11,102,063 11,421,041
b = kWh of electricity entering system 207,165,465 211,261,285 197,992,332 201,936,757
Loss ratio % 7.0% 4.5% 5.6% 5.7%

(c) Capacity utilisation (=(a/b)*100)

2004 2003 2002 2001
a = Maximum demand 36,024 38,232 35,650 34,776
b = Transformer Capacity 116,726 109,003 104,363 107,127
Capacity utilisation % 31% 35% 34% 32%
