<strong>The</strong> overall picture on system loss is not encouraging as shown in Figure A.13. Most <strong>Pacific</strong><br />

countries have system loss percentages well into double figures with the highest in FSM,<br />

Tonga and Samoa, where system losses are running above 17.5%. Vanuatu and Fiji show<br />

that it is possible to do much better than this.<br />

Service Quality<br />

Quality of electricity service is measured by its reliability, and by the stability of frequency<br />

and voltage. Most utilities in the <strong>Pacific</strong> region do not collect data on frequency and voltage<br />

fluctuations in the grid, but we were able to get data on reliability for some countries,<br />

measured as hours of lost supply per customer per year.<br />
