Disclosure of Energy Efficiency Performance Measuring and Statistics
Pursuant to Regulation 15 Electricity (Information Disclosure)
Regulations 1994

1. Energy delivery efficiency performance measures

(a) Load factor 63.5%

Percentage of electrical energy entering the transmission system over
maximum demand times hours per year.

(b) Loss ratio 5.2%

Transmission losses over electricity entering the system during the financial
year.

(c) Capacity utilisation 25.7%

Maximum demand over total transformer capacity

2. Statistics

(a),(b) and (c) System length, broken down by nominal line voltages and sub-analysed into overhead and underground categories:
