No. 91

ELECTRICITY INVERCARGILL LIMITED LINE BUSINESS ENERGY EFFICIENCY PERFORMANCE MEASURES

PURSUANT TO REGULATION 21 OF THE ELECTRICITY (INFORMATION DISCLOSURE) REGULATIONS 1999 AS AMENDED BY THE ELECTRICITY (INFORMATION DISCLOSURE) AMENDMENT REGULATIONS 2000

Energy Delivery Efficiency Performance Measures Years Ending 31 March 1999, 2000, 2001 and 2002

	2002	2001	2000	1999
(e) Load Factor (Percentage of electrical energy entering the transmission system over maximum demand times hours per year.)	48.6%	51.6%	54.9%	53.1%
(f) Loss Ratio (Transmission losses over energy entering the system)	4.0%	4.5%	4.0%	3.7%
(g) Capacity Utilisation (Maximum demand over total transformer capacity)	44.1%	41.5%	38.5%	41.7%

The loss ratio for the 2002 year of 11.0% is derived from electricity supplied information provided by other parties. Electricity Invercargill Limited is unable to audit this information and has little confidence in its accuracy and has therefore estimated losses for this year at 4.0%.

As the Gazette has been published for more than 185 years, copyright status depends on the publication date of each issue:

1840–1925 (Public Domain): Issues of the New Zealand Gazette and Provincial Gazettes from this period are in the public domain, as the term of Crown copyright (100 years) has expired. Mechanical reproductions (e.g., scanned PDFs) of these public domain documents do not attract new copyright.
1926–1999 (Crown Copyright): Issues from this period remain subject to Crown copyright. Usage of these issues in this project is "Fair Dealing" for research purposes and consistent with the spirit of the open-access principles championed by NZGOAL, ie, "The default licensing position under ...
