Section 1: Asset Management Plan Update
1 Asset Management Plan Update This supplement to our Asset Management Plan published in March 2018 (for the period 2018-2028) provides an update to Northpower’s approach to managing its assets and delivering the planned programmes of capital and operational spend, as well as planned maintenance work for the period 1 April 2020 to 31 March 2030.
Northpower’s 2018 Asset Management Plan is available from Northpower’s website at: http://northpower.com/about/disclosures/asset-management-plan. This update should be read in conjunction with the 2018 AMP (and subsequent 2019 AMP Update) and outlines how we are managing our Network assets for the efficient and reliable delivery of electricity to consumers.
Covered in this update are:
1. Material changes to the network development plans disclosed in the last AMP;
2. Material changes to the lifecycle asset management (maintenance and renewal) plans disclosed in the last AMP;
3. Material changes to Northpower’s asset management practices; and
4. An outline of the reasons for material changes to the previous disclosures in the Report on Forecast Capital Expenditure set out in Schedule 11a and Report on Forecast Operational Expenditure set out in Schedule 11b.
Stakeholder FeedbackNorthpower encourages feedback to enable continued improvement in meeting the needs of its consumers and stakeholders.
Feedback should be addressed to:

Section 2: Material Changes
2 Material Changes
2.1 Overview Since the 2019 AMP Update we have continued to review the existing Asset Management Plan for the electricity business and our approach to investment and maintenance with a focus on continual improvement. The key inputs into this review have included:
• A full review of forecast changes in investment need relating to aging major items of plant and load growth for the 10-year planning period FY21-FY30.
• A full review of unit costs associated with our investment programmes, noting a general trend to increased delivery costs across all work delivery streams.
• Reviewing security of supply criteria against updated load and growth forecasts for high growth areas (primarily Mangawhai and Bream Bay).
• A review of Opex and Capex programs to ensure SAIDI and SAIFI remain in line with long-term averages, taking into account an aging asset base, increases in planned work and ongoing vegetation challenges.
This 2020 AMP Update summarises the resulting changes to our Asset Management Plan.
2.2 Material Changes to Network Development Plan
Overall $18.0M increase in the 10-year Network Development profile compared with the 2019 Asset Management Plan Update1
We have reviewed the Network development investments for the next 10-year period and revisited growth assumptions to validate investment need. As a result, some projects have been deferred out of the 10-year planning period.
Counteracting this deferment outcome, and to ensure security of supply to areas experiencing high residential and industrial growth, we have brought forward two significant projects in Mangawhai and Bream Bay and made a number of other targeted changes as set out in the table below.
Material Changes to Network Development Plan2
Year Change ($) Description of Change Reasons for change
FY21 - FY24 +10.5M Second Maungaturoto - Mangawhai sub-transmission line
To address high levels of growth in the area, and to meet Northpower’s security of supply standards.
FY20 - FY29 +4.9M Provision for growth in customer connections
Updated forecasts in line with recent growth trends.
FY21 - FY25 +4.5M Provision for Bream Bay area development (second transformer, switchboards)
Revision of residential and commercial growth forecasts for the area indicate a need to revisit and consolidate investment plans.
FY20 - FY29 +2.7M Increase in overhead to underground relocations in specific coastal areas
To address asset corrosion, improve reliability and extend asset lifecycles.
FY20 - FY29 +1.3M Increase distribution transformer relocation from overhead platforms
Acceleration of targeted safety programme.
FY20-FY29 +3.9M Buildings, civil and electrical contractor cost increases
Reflects uplift in costs across industry, following cost validation exercise.
FY19 - FY29 -12.3M Project deferrals Largely due to revision of growth forecasts deferring investment need out of the planning period.
The resulting investment profile sees an uplift in investment related to Network Development compared with our 2019 AMP Update, particularly in the first five years of the planning period.
1 For the comparison period FY20 to FY292 Includes the following investment categories: consumer connections, system growth, asset relocations, reliability,
safety & environment)

2.3 Material Changes to Asset Life Cycle Management
Overall $24.7M increase in the 10-year Asset Life Cycle Management profile compared with the 2019 Asset Management Plan Update.3
Our latest review of our Asset Life Cycle Management Plan noted a material increase in building, civils and electrical contractor market rates. We have validated that these increases are real and likely to persist into the future even with competitive pressure. We will continue to look at options available to ensure these project works are delivered in the most cost effective manner.
We have also revised and improved our overhead inspection standard to improve the quality of inspection data received, which in turn enables enhanced asset condition assessments and replacement decisions. The key changes proposed are set out in the table below:
Material Changes to Asset Life Cycle Management Plan4
Year Change ($) Description of Change Reason for change FY22 - FY23 +2.5M New mobile substation To enhance restoration of supply in fault
situations and enable supply to be maintained during rural substation maintenance.
FY20 - FY29 +2.3M Oil filled RMUs Increase in rate of replacement of RMUs as a result of condition based assessments.
FY21 - FY29 +1.3M New allocation corrective Capex - 110kV towers & equipment
To reflect increased need following condition assessments.
FY21 - FY27 +1.2M New network clearances 3D model (LiDAR)
To enable enhanced management of vegetation priorities and asset clearances.
FY22 - FY24 +1.2M Asset management system replacement
Replacement of end of life system.
FY21 - FY29 +2.5M Provision for overhead switch replacements
Increased need based on emerging defect rates in existing overhead switches.
FY20 - FY29 +15.7M Buildings, civil and electrical contractor cost increases
Reflects existing uplift in costs across industry, following cost validation exercise.
FY19 - FY29 -6.0M Targeted deferrals Result of validation of asset condition and resulting amendments to the asset’s Health Indices.

Responding to service interruptions and emergencies
+$2.11M Uplift to address aging network and an allowance for increased faults due to more significant weather events stressing end of life overhead assets.
Vegetation management +$4.80M An uplift in vegetation management to deliver a 5-year vegetation management cycle (better aligned with tree growth rates).
Routine and corrective maintenance and inspection activities
+$5.47M Increase in quantities of corrective maintenance to ensure focus remains on ensuring timeliness of rectifying defects and enhancing maintenance programmes, as well as an increase in contractor costs.
Asset replacement and renewal
+$573k Impact of contractor rates review for asset replacement and renewal activities.
System operations and network support
+$2.13M Reflects ongoing investment in ADMS and maintaining supporting systems, as well as enhanced operational capability and resiliency.
Business support +$15.94M Reflects increases in direct and indirect costs to support the network.
2.5 Material Changes to Asset Management PracticesThe 2019 AMP Update outlined a number of initiatives aimed to improve our asset management processes. Further refinement over the last year includes:
• Revision of our Network organisational structure to improve focus and outcomes in asset management and delivery of capital and maintenance works. This is supplemented by additional resources to support the asset strategy, delivery and operations functions.
• Refresh of the overhead inspection standards to facilitate better information capture, and ultimately asset management decisions.
• We have further developed our Asset Health Indices and Asset Criticality processes and framework. Several assets have had condition assessments undertaken (including some sub-transmission conductors and zone sub-station transformers), resulting in a re-classification of the asset’s Health Indices (and an adjustment to the investment plan).
