β¨ Electricity Performance Measures
23 AUGUST NEW ZEALAND GAZETTE 2603
MARLBOROUGH LINES LIMITED
PERFORMANCE MEASURES FOR THE LINES BUSINESS
PREPARED IN ACCORDANCE WITH THE
ELECTRICITY (INFORMATION DISCLOSURE) REGULATIONS 1999
and ELECTRICITY (INFORMATION DISCLOSURE) AMENDMENT REGULATIONS 2000
notes Energy conveyed through the system, and the resultant Loss Ratio calculation is reliant on information provided by Electricity Retailers. Due to the inability of some Retailers to provide accurate consumption information, Marlborough Lines cannot assure readers as to the accuracy of performance measures based on these factors, or on the volumes conveyed for some retailers.
Previous Regulations required the system length and consumer numbers to be taken as the average of the opening and closing totals in each year. The June 2000 Amendment to the Regulations removes these requirements. Accordingly, it is assumed that Consumer Numbers and System Length statistics, on which a number of performance measures are based, should be disclosed as the total at 31 March. This results in a one-off abnormal growth in each of these factors.
The number of consumers includes a small number of installations where consumption is estimated on the basis of known load, rather than recorded by metering equipment.
