54 Auckland’s Strategic Direction — Executive Summary

Our Auckland Strategy will look at the drivers for change on the Grid in Auckland and how we can best support and plan for those changes.

It will seek to respond to, and plan for, new technologies, growth, and our long-term major maintenance programme. This will ensure that in the future we can:

• provide efficient and resilient transmission services;

• sustain operational and maintenance flexibility;

• optimise our current infrastructure;

• enable agility through innovation.

The strategy scope includes:

• keeping high levels of security of supply across Auckland and Northland;

• developing options up to the late 2050s;

• designing to meet Transpower’s prudent load forecast, with flexibility for an uncertain future e.g. new technologies;

• retaining the ability for the 220kV line into South Auckland to operate at 400kV through our substation work;

• working with Vector and Counties Power to ensure a sufficient and reliable supply of electricity for their end customers.

Final Auckland Strategy (June 2018)

We are here Interim findings and emerging strategy

6 7Auckland’s Strategic Direction — Executive Summary

Key findings so far• Our current infrastructure and

assets are enough to provide a secure and reliable supply well into the 2040s, even with increased electricity consumption and population growth.

• All our lines in Auckland need major maintenance at different times over the next 30 years.

• Undergrounding everything isn’t the answer — it comes with significant costs and technical challenges.

• Some future projects in the Auckland Strategy may require third party financial support.

• The cost of electricity remains a concern to NZ’s electricity consumers.

• Our 220kV network is essential for the bulk transfer of electricity into, across and through Auckland. The 110kV network is not as essential for this function.

Key opportunities• Auckland’s 110kV lines are

legacy assets and most now act as a distribution network. There are opportunties to rationalise them over time.

• New technologies (e.g. batteries and solar PV) may provide an opportunity to defer future investments and get the most out of our existing assets.

• The complexity of the major maintenance work means we will be trialling and implementing new transmission technologies and new construction practices — our aim is to undertake our work in Auckland with the least disruption to the community as possible.

Emerging strategy• The 220kV network will remain and

be maintained over time. This part of the Grid will still be needed in the future, as it provides the backbone electricity network into, across and through Auckland.

• We will look to rationalise our footprint where practicable — there are opportunities especially with the 110kV network. This work will happen over time, triggered by the need for major maintenance or where there is a conflict with another significant infrastructure project e.g. road, rail, housing.

• Central Auckland: We will retain the 220kV lines and undertake major maintenance over the coming decades. We may remove approximately 60km of 110kV lines over the next 40 years. A new cross-Auckland cable may be required around 2040.

• South Auckland: We will retain the 220kV lines and undertake major maintenance over time. We may remove 110kV lines where practicable. A new cable in South-East Auckland may be built around 2030.

Starting in the 1920s, the Grid has developed through and around Auckland’s narrow isthmus and up into Northland.

The lines and substations were established on the rural outskirts of the city, that developed into suburbs as Auckland grew. The Grid now shares these urban spaces with communities.

As Auckland grew, so did the Grid and its capacity. The first 110kV lines were built in the 1940s followed by the larger 220kV in the 1960s, and the high capacity line and cable in the early 2010s.

In Auckland we have approximately 300km of overhead lines and 55km of underground cables.

The investments in the early 2010s have put us in a good place — we are able to maintain a safe, secure electricity supply to Auckland and Northland, and have secured Auckland’s electricity needs into the future (for at least the next 20 years).

In the past three years Auckland-based electricity generation has reduced despite Auckland growing. We now bring the majority of our electricity from the south: 95% of peak electricity demand for Auckland and Northland comes from generation sources in the central North Island and South Island (predominantly renewable hydro, wind and geothermal generation).

Our history and the Grid today

We have approximately 300km of overhead lines in Auckland, and 55km of underground cables.

What’s driving us?• Our long-term major

maintenance programme.

• Changes in technology in the electricity industry and other related sectors, changes in electricity use.

• Auckland’s development and growth plans — especially the large infrastructure projects for housing and transport, and associated services (e.g. water). Our assets can be a constraint for those developments and often need to be designed around, or moved to accommodate growth.

Looking after what we haveOur lines were built in the 1940s and 1960s and we built them to last a long time. It is now time to start to refurbish them — this means a significant programme of major maintenance over the next 30+ years.

This major maintenance programme will include rewiring (reconductoring) and tower maintenance (painting, foundations). This is routine work for us as we maintain the Grid for the future.

Maintenance of our lines does have its challenges:

• our assets are in urban areas — a large number of buildings and houses are built under our lines;

• construction activities will cause disruption for local communites, even with our efforts to reduce this disruption;

• the work is technically complex and costly;

• the work is resource intensive and we anticipate labour shortages in Auckland.

Given the challenges of working in urban Auckland, we need to think differently about how to plan and deliver our work programme.

We constantly seek to be efficient and avoid unnecessary price increases for electricity consumers.

Electricity demand growthA greater population means an increase in electricity usage — but we’re not sure how much of that power will be needed from us. It is highly likely for the foreseeable future that Auckland demand:

• Will remain at least as high as it is now.

• Is expected to increase at a rate of about 1% a year, but no higher than 2% a year on average. Note: 1% = adding the amount of power used in Hamilton to Auckland’s electricity demand every 10 years.

Solar and Solar PVSolar panels to supplement or replace household power supply have become more common and growth has been rapid.

By themselves, solar panels do not reduce the need for a transmission system. This is because their time of peak generation is in the middle of a sunny summer day, while peak demand typically occurs on cold winter evenings. To solve this mismatch, batteries known as a solar PV system, are needed.

Electricity generation developmentMost of Auckland’s electricity is generated outside of the region. There is potential for new generation in both Auckland and Northland, however there is no guarantee that will happen as many of the generation options have been on the planning books for well over five years. In any event, even if all were to occur, Auckland would still not be self-sufficient in electricity.

Battery storageBattery technology continues to develop and in time will be a game-changer for the power system. We see it as a useful tool for us and others in the industry, as well as for homes and businesses. We expect use to increase as the costs of batteries continue to decline.

Long term, we expect that battery or other storage technologies will alter our business by covering short-term imbalances in supply and demand, and by smoothing out daily peaks.

Our recent research indicates that batteries are likely to present best value when located near places of high electricity demand (such as major cities), and that benefits are variable.

Energy efficiencyEnergy efficiency will continue to play its part in reducing overall electricity demand through a variety of ways. These include industry improvements, new warm houses built and retrofitting existing housing stock, and the continued evolution of energy efficient products for homes and businesses.

Electric vehiclesGiven the benefits include emission reductions, lower running costs, and in some cases Government support programmes, we anticipate uptake of electric vehicles will be rapid. Government policy is targeting 64,000 by 2021/22.

In future, we expect that electric vehicle batteries could have capability to be part of a battery network, providing services when the vehicle is plugged in to charge overnight.

The future: Technology

An important part of the equation is the trends in electricity generation, transmission and consumption that might change how Auckland’s electricity is supplied. Our investigations into growth, generation, and technologies have identified these key findings.

18 Auckland’s Strategic Direction — Background 19

From Transmission Tomorrow, our vision for the future of the National Grid, we know there are a number of trends that are driving change, fast, in the electricity sector.

• Distributed generation and storage, such as solar and batteries — opportunities to smooth demand peaks.

• Electrification — industrial processes switching to electricity, electric vehicles.

• Energy consumption — we are becoming more efficient users of electricity, but this will be lessened by an increase in electrification.

• Smart grids — networked digital devices in homes, businesses and on the network offer potential for a more efficient electricity system.

• Urbanisation — we are becoming more urbanised, with growth in the upper North Island, in particular Auckland.

• Climate change policy and changing social attitudes — will drive a shift towards electricity (substituting fossil fuels).

Transmission Tomorrow is available on our website.

What does this mean for Auckland?The Grid will still be needed to supply power to, around, and through Auckland. Our lines and substations will still be critical infrastructure in the future.

We need to be flexible given the uncertain future, and to plan for changes over time.

With these changes we are looking at our network, development plans and business processes in a different way: broader and further into the future. Technology will drive a change in the way we do things at Transpower.

Where assets are required in the long-term, we need to continue to maintain them to ensure a secure and resilient electricity service in the future.

Due to the changes on the horizon, we need to think carefully before building any new assets, in order to avoid over-investing.

Our future: Transmission Tomorrow

We are frequently asked to relocate our assets to enable roading and rail projects, or to underground, consolidate or relocate lines to enable housing development. Increasingly, other ancillary infrastructure is also impacting our assets, e.g. water and fibre.

And, as a normal day to day activity, we also need to work in our substations to ensure that Auckland’s distribution companies Vector and Counties Power, and our direct

connect customer New Zealand Steel, continue to be supplied with electricity.

We estimate we will undertake at least $350M of work on the Grid in Auckland over the next five years, for known infrastructure projects, to enable transport and housing developments, and to ensure our customers can meet electricity demand. Much of this work is funded by the transport or housing developer, or distribution company.

2322 Auckland’s Strategic Direction — Our Auckland Strategy

It is about how we are planning our work now, to support Auckland’s growth, in a way that recognises the electricity sector’s uncertain future. Because the vast majority of Auckland’s future electricity needs can be supplied by the existing Grid, we’ve taken the opportunity to consider how we optimise the Grid for the future, given the major maintenance that must be undertaken.

Our interim findings and emerging strategy bring all these drivers together.

Our Auckland Strategy

24 Auckland’s Strategic Direction — Our Auckland Strategy 25

Developing our emerging strategyOur interim findings come from a range of work streams — investigations and research, technical analysis and assessment, and stakeholder engagement.

28 29Auckland’s Strategic Direction — Our Auckland Strategy

Key findings

Taking into account the options, issues and challenges, costs and risks, and what our key stakeholders had to say, we found that our final Auckland Strategy must meet the following principles:

Even with higher than expected load growth, we have enough infrastructure to provide Auckland with a resilient electricity supply for the next 20 years due to our investment programme in the early-2010s.

Our lines in Auckland will require significant maintenance work at different times over the next 30 years.

The 220kV network is vital to the supply of Auckland’s electricity — it is the backbone of Auckland’s Grid. A new cable in South-East Auckland may be required around 2030 and a new cross-Auckland cable may be required around 2040.

The 110kV network, while it has played an important role, now acts largely as a distribution network. There may be opportunities to rationalise parts of the 110kV network over time.

Where assets are required in the long-term, we need to continue to maintain them to ensure a secure and resilient electricity service in the future.

Some communities have asked us to underground our lines as they can pose a constraint on development and have a visual impact. Undergrounding is not an easy answer to these problems — it is costly, technically complex, and outages following a fault are likely to be significantly longer.

We know that some options may require third party financial support to enable them to occur —undergrounding would be one of these. This is because our current regulatory funding framework is based on a least-cost to New Zealand principle: the cost of most of our assets in Auckland is spread across all New Zealand electricity consumers. Some assets are funded by the beneficiary customer e.g. Vector.

Emerging strategy: Central Auckland

Our emerging strategy identifies which overhead lines are to remain and need maintaining. It rationalises the Grid’s footprint, where practicable, in a way that creates the least impacts — it reduces, rather than increases impacts on communities.

Our emerging strategy for Central Auckland would:

• retain the 220kV lines and continue to maintain them;

• remove approximately 60km of 110kV overhead line, including from the Manukau Harbour shoreline, and most of the 110kV lines between Albany, Henderson and Otahuhu;

• retain the 110kV lines between Hepburn Road and Mt Roskill substations; and

• install two new underground cables, one across Auckland (Pakuranga – Albany) and one between Brownhill and Otahuhu.

In order to enable this we would need to:

• build a short 700m overhead line to connect the 220kV line to Hepburn Road substation to facilitate removal of the 110kV lines between Henderson and Otahuhu; and

• build new equipment at substations.

We note again that each project will be assessed on its merits at the time detailed planning occurs.

We considered removing the 220kV lines from the Manukau Harbour shoreline. This option is significantly more complex than our emerging strategy because it would require rebuilding these lines over residential areas or undergrounding them which will have considerable environmental and property challenges.

We considered removal of all 110kV lines. Again, this option is significantly

more complex than our emerging strategy because it would require a cable termination station located in a residential area to connect the Mt Roskill substation to the 220kV line. Similarly, this would pose considerable environmental and property challenges.

We considered undergrounding of lines. This option is significantly more expensive (approximately $4B+) and technically complex. Lines can’t be removed until underground cables are in service and this would take decades to achieve. Additionally, the gap between what Transpower could fund under the current regulatory funding framework and the costs to underground are significant.

Emerging strategy: South Auckland

33

Our work in South Auckland is further ahead than Central Auckland — a number of investigations and projects are already underway.

Our emerging strategy for South Auckland would:

• retain the 220kV lines and continue to maintain them;

• retain and upgrade the 110kV line between Otahuhu and Wiri;

• remove approximately 25km of 110kV line between Bombay and Wiri (currently under investigation);

• build new equipment at substations; and

• remove approximately 140km of 110kV line between Bombay and Hamilton (currently under investigation).

While the final Auckland Strategy provides the direction for where we are heading, we know that this work will happen over a long time period (40 years). Therefore it is important that each project is assessed on its merits — this will occur when the lines are ready for major maintenance, or other infrastructure projects conflict with our assets. At this stage we will investigate whether we can rationalise these assets instead of maintaining them for the future.

Undergrounding

Some communities have asked us to underground our lines as they can pose a constraint on development and have a visual impact.

Getting ready for our work

We considered undergrounding all or parts of the network as part of our process and it was put through the multi-criteria analysis alongside all other options.

Undergrounding is technically feasible and would remove the visual impacts of overhead lines. It would also free up land to enable further growth.

But, it is not without its challenges.

• It’s not a quick fix — lines couldn’t be removed until underground cables were in service — which could be many decades away.

• Finding suitable underground routes for new cables, free of conflicting infrastructure e.g. gas, would be challenging. Other infrastructure would likely need to be relocated and/or be prevented from co-locating in the vicinity of underground cables. Significant disruption of the road network would also occur during construction and potentially during maintenance and fault repairs.

We are investigating technological advances in transmission line engineering, technology, and maintenance techniques which will help us to work in urban environments.

These include new types of equipment and conductor and innovative work methods and practices to assist us to reduce disruption to our communities.

We are also looking into how new technologies (e.g. batteries) provide an opportunity to defer future investments and get the most out of our existing assets.

We are investigating building a new training facility to trial these new technologies and procedures.

We will continue to monitor new technologies and changes in demand.

We will work with our regulators to facilitate regulatory approvals for projects.

• Cable faults are harder to locate and fix than for overhead lines. This potentially means longer outages or times on lower security supply levels. To counter this, we would need to install multiple cables on diverse routes and this adds to the costs.

• Costs to underground all lines in Auckland are significant, approximately $4B+. Initial construction costs, and operation and maintenance costs are higher than for overhead lines. Underground cables also have a shorter lifespan than overhead lines, so would need to be replaced earlier.

• The gap between what Transpower could fund under its current regulatory funding framework and the costs of undergrounding are likely to be significant. We also consider it unlikely that funds would be available from a third party (e.g. Auckland Council), given Auckland’s current infrastructure priorities.

Many of the undergrounding benefits can be met from removal or rationalisation of transmission lines — but with fewer challenges.

On balance, we consider undergrounding shouldn’t be pursued at a strategy level although undergrounding of some individual lines at a project level would continue to be considered. (for instance, to enable housing development subject to the developer funding it).

Our funding framework for major maintenance

As a regulated monopoly Transpower’s funding is set by the Commerce Commission to ensure the money we spend provides long-term benefits to New Zealand electricity consumers.

The Commerce Commission establishes various processes to ensure this objective can be followed.

Funding for our projects is recovered from electricity consumers nationwide via electricity retailers, making up a fixed charge on electricity bills.

We constantly seek to be efficient and avoid unnecessary price increases for electricity consumers.

Grid Investment Test methodology (Commerce Commission)Principle: highest consumer benefit for lowest life cycle cost

Options analysed and alternatives considered in project investigation

Rationalisation or removal is the same cost or cheaper than retaining and maintaining into the future

Transpower funds on business as usual

Need 3rd party funding for deficit in project cost for project to proceedExample: Total cost of project $35M (undergrounding a section of line).

Retention of the line and maintenance (reconductoring) is least cost for NZ electricity consumers $15M.

Deficit in funding $20M. Would need to come from a 3rd party.

Rationalisation or removal is more expensive than retaining and maintaining into the future

Transpower pays for option with highest consumer benefit for lowest lifecycle cost
