Electricity Distribution Information Disclosure Determination 2012 – (consolidated in 2015) – Schedules 14-15

Box 12: Explanatory comment on variance in actual to forecast expenditure

Overall, actual capital expenditure on network assets was 46% higher than the target capital expenditure. Consumer connections expenditure was higher than forecast due to an upsurge in the number of new subdivisions during FY16. Reliability, safety and environment costs was lower in FY 16 due to timing (or deferral) of implementation of the relevant projects planned for the year. System growth of 1223% was due to the growth in the zone substation and sub transmission area.

Overall, actual network operating expenditure was 22% higher to target due to an increased spend on service interruptions and emergencies, asset replacement and renewal and vegetation management. This was a result of poor weather conditions and a couple of major transformer malfunctions.

Information relating to revenues and quantities for the disclosure year

16. In the box below provide-

16.1 a comparison of the target revenue disclosed before the start of the disclosure year, in accordance with clause 2.4.1 and subclause 2.4.3(3) to total billed line charge revenue for the disclosure year, as disclosed in

Schedule 8; and

16.2 explanatory comment on reasons for any material differences between target revenue and total billed line charge revenue.

Box 13: Explanatory comment relating to revenue for the disclosure year

Target revenue disclosed before the start of the year was lower (2%) than the total billed line charge revenue for the disclosure year. No material movement between target revenue and total billed line charge revenue noted.

Network Reliability for the Disclosure Year (Schedule 10)

disclosed in Schedule 10.

Page 43: EDB Information Disclosure Requirements Information ... · EDB-ID-determination-templates-for-schedules-1-to-10-v4.1-24-March-2016.xlsx 13 S2.Return on Investment Company Name For

Electricity Distribution Information Disclosure Determination 2012 – (consolidated in 2015) – Schedules 14-15

Box 14: Commentary on network reliability for the disclosure year

SAIFI for the disclosure year was measured at 2.16 interruptions per customer.

The target for planned SAIDI of 55 minutes was not achieved and the result of 67 minutes was largely due to the amount and nature of asset-replacement work on the network. Unplanned SAIDI target of 90 minutes was achieved with a result of 67 minutes. This was mainly due to more favourable winter weather conditions than had been experienced in previous years.

Insurance cover

18. In the box below, provide details of any insurance cover for the assets used to

provide electricity distribution services, including-

18.1 The EDB’s approaches and practices in regard to the insurance of assets used to provide electricity distribution services, including the level of insurance;

18.2 In respect of any self insurance, the level of reserves, details of how reserves

are managed and invested, and details of any reinsurance.

Box 15: Explanation of insurance cover

Significant assets located in one place (e.g. zone substations, control room) are insured under a comprehensive replacement insurance policy. Assets that are spread over a large

area (e.g. lines, cables and distribution transformers) are uninsured.

Box 1: Voluntary explanatory comment on disclosed information

In disclosing our target revenue in Schedule 7(i),we note that the section in the Northpower pricing methodology that is noted in Appendix 2 as meeting the requirement of clause 2.4.3(3) of the ID Determination (section 9.6) actually represents past revenue information rather than target revenue figures. This then results in a situation where there is no previously disclosed value to use when completing cell H8 of Schedule 7(i). We have therefore used the budgeted revenue figure as approved by the Board in cell H8 of Schedule 7(i).
