Your views on our proposed 2018/19 appropriations and focus
We invite you to share your views on our proposed appropriations for the 2018/19 year and the focus of our work programme.
The Authority is funded by the Crown through appropriations of public money. The Crown recovers the cost of this funding through the Electricity Industry levy on industry participants.
Before requesting this funding, each year we consult with levy payers in the electricity industry to take on board their feedback, improve our focus and comply with our requirements under the Electricity Industry Act (2010).
For 2018/19 we are proposing funding of $74.270 million to enable us to deliver core functions and progress our work to promote a competitive, reliable and efficient industry for the long term benefit of consumers.
More than 70 per cent of this money will fund the operation of the electricity system and market, with the remainder used to fund the Authority’s core operating expenses and work targeted at facilitating consumer participation.
In addition to our core operational appropriation, we also seek funding for two contingent appropriations: Managing the security of New Zealand’s electricity supply and the Electricity litigation fund. For 2018/19 we are proposing that these appropriations stay at the same level as in 2017/18.

Proposed Electricity industry governance and market operations appropriation in 2018/19 ($74.270 million)
What’s different this year
The electricity industry is undergoing transformation and responding to evolving technology, changing consumer expectations and increasing uncertainty. A significant commitment to market development is needed to ensure the industry remains flexible into the future so that consumers can make the most of opportunities resulting from innovation.
For the Electricity industry governance and market operations appropriation, our proposal of $74.270 million is a slight increase of $0.333 million from 2017/18.
This reflects a small increase in funding that we consulted on last year to enable the system operator to deliver improvements to its Electronic Dispatch Facility.
We are also seeking feedback about extra funding from 2021/22 that would be needed to enable the Authority’s Board to make a decision to implement real-time pricing. Implementing real-time pricing will provide much better price certainty and unlock a range of opportunities for new technologies and new business models.
Our work programme
We’re also seeking feedback on the six programmes covering our key project work. These programmes are aligned with our strategies for delivering long term benefit for consumers.
To help you understand more about how they align, we’ve included a short table that summarises the links between the programmes and strategies below.
We need your views by 5 pm on 19 December. We always get great value from the input our stakeholders and levy payers provide and we appreciate the effort you put into this process.
The appropriations will be announced in the Government’s Budget, which usually occurs in mid-May. The detailed information will be published in the Authority’s Statement of Performance Expectations (SPE) for 2018/2019.
More detail including the full consultation documents are available on our website.
Note—we have corrected a typo in the consultation paper affecting Question 6 (Page 19). This question should refer to 2018/19 as opposed to 2017/18. The link to the consultation paper now refers to the document with this corrected.

Financial Transmission Rights - successful product for managing risk
In June 2013, the Authority started the Financial Transmission Rights (FTR) market. The successful development of this financial risk management tool is helping the wholesale market mature.
The chart shows the amount of transmission price risk covered by FTRs each year since this market was launched in 2013.
Volume of FTRs covered - (GWh)
The Authority introduced FTRs to help generators and retailers manage the future price risk from transmitting electricity across different geographical points in the country. This price difference is caused by constraints and losses that exist on the transmission network. (The risk is very much like the exchange rate risk for importers and exporters)
The FTR manager has been able to increase the volume of FTRs available, measured in terms of GWh. This has mainly been because initial success of this market has meant the Authority increased the number of FTR hubs from two in 2013 to five in 2014 and eight now.
Another measure of success is the participants have broadened from generators, large industrial users and retailers, to increasingly also proprietary traders who use this product to be more active and support liquidity in the ASX futures and options market. Also, as a result of this increasing competition, the auction prices for FTRs have moved closer to a more cost-efficient level, that is, better reflecting the network costs involved.

Our People Series - Tuong Nguyen
Designing and operating New Zealand’s electricity system takes great people. In this series, we shine a light on a selection of our staff members. This month we spoke to Tuong Nguyen from the Market Analytics team.
The Authority continually monitors the wholesale electricity market and identifies areas for development. This market development work wouldn’t be possible without a team of expert data analysts working behind the scenes.
Senior Analyst, Tuong Nguyen is one of these experts. Tuong works in the Market Analytics team – who are responsible for managing the provision of modelling and data analysis to support the Authority’s wider work.
For Tuong this means wading through large sets of complex data and finding ways to make it meaningful and helpful for other teams.
“We have a lot of data to work with in our data warehouse and great tools to analyse it,” says Tuong. “This makes it much easier for the Authority to see what goes on in the market and check the market works as expected.”
A lot of this data is then made publicly available through the EMI website in the form of graphs and tables.
The team receives data from a number of sources on a daily basis and it’s important that this information is up-to-date and correct.
Like any good data analyst, Tuong uses his eye for detail to spot when something isn’t quite right.
“I’m always busy looking through data. If I notice something doesn’t look right I’ll investigate it further and dig up more data,” says Tuong. He’ll then raise this with the appropriate team in the organisation.
Next year, Tuong will celebrate ten years with the Market Analytics team – he joined shortly after the Electricity Authority was established. Tuong has built up an extensive knowledge and interest in the wholesale electricity market while at the Authority, as well as during previous roles at Transpower and Contact.
Tuong was based in Singapore working for the Energy Market Company when a friend told him of a job opening at Transpower. He jumped at the chance to move to New Zealand to join the electricity industry here.
Since joining the Authority Tuong has helped on many of the Authority’s wholesale market development projects. At the moment he is busy supporting the Real-time pricing project team with data analysis and modelling to check the impact of their proposed changes.
“I enjoy working with the different teams across the organisation – there are some very intelligent people here,” he says. “In their roles they may not have the data or tools so that’s where I can help.”

Managing security of supply
We are proposing changes to the regulatory settings for official conservation campaigns – one of the key tools we use to manage security of supply.
The main challenge to security of supply in New Zealand is a dry year because of our significant reliance on hydro generation. If there is low rainfall it means the lakes that provide the water for this generation can also be low.
To manage the risk posed by low lake levels we have a number of tools in place, including the ability to call an official conservation campaign (OCC). If an OCC is called, the system operator (Transpower) will ask New Zealanders to voluntarily reduce their electricity usage. Residential customers and other small consumers are then paid $10.50 a week compensation by their retailers.
Since the OCC scheme was introduced on 1 April 2011, the starting point of an OCC has been defined by the 10 per cent hydro risk curve (the red line on the below chart). If hydro storage (the blue line) drops to this level there would be a 10 per cent chance of running out of remaining hydro storage if no efforts were made to reduce electricity usage.
Hydro risk curves
Alongside Transpower, we monitor and assess security of supply to ensure participants have the information and incentives needed for the electricity system to operate efficiently. We also regularly assess whether the tools to manage security of supply, such as OCCs, are working as they should be.
Recently, Transpower has proposed amendments to the calculation of the hydro risk curves. They propose that these would be improved if contingent storage was included in the assessment.
Contingent storage is hydro storage not ordinarily available for generating electricity, but which becomes available when hydro lake levels are low. Three of the major hydro lakes in New Zealand have some storage classified in this way: Tekapo, Pukaki and Hāwea.
As Transpower’s proposed changes could have an effect on how OCCs start and end, we are proposing some complementary changes to OCCs. We are interested to hear if participants agree whether the 10 per cent hydro risk curve (calculated inclusive of contingent storage) should be used to trigger the start of an OCC, and whether our suggestions on ending an OCC should be introduced.
We would also like to get your view on other aspects of the OCCs, including the current geographical extent of OCCs. Currently there are two forms of OCC: South Island-only and New Zealand-wide. We are considering the possible removal of the South Island-only OCC for several reasons, including the possible confusion this could cause among consumers when they are asked to conserve electricity.
Together, the changes proposed by the Authority and the system operator are likely to affect when OCCs are triggered and hence how dry year risk will be managed in the future. We expect the change would promote reliability of electricity supply and the efficient operation of the electricity industry.
We’re interested to hear your opinions on what we’re proposing. The consultation is open until 5pm on 11 February 2019.

Wholesale market update, Spring 2018
In this Market Commentary, Authority chief executive James Stevenson-Wallace gives observations on what’s been happening in the spot market recently.
Update - 15 November
The situation has eased in the past two weeks, due to reducing demand with warmer weather, rainfall flowing into hydro lakes and strong wind generation. Gas production remains constrained, and we are working with the industry to monitor this.
Strong inflows have increased storage rapidly—national controlled storage
Prices have fallen—average daily spot prices at Benmore and Otahuhu
Forward prices have come down: quarterly forward curve at Benmore and Otahuhu compared with one week prior
In the meantime, on Thursday, 8 November 2018 we received a claim of an undesirable trading situation (UTS). The claim has been made by five parties – Electric Kiwi Limited, Flick Energy Limited, Pulse Energy, Switch Utilities Limited and Vector Limited. The claim relates to the period from 15 September 2018 onwards. The Authority is investigating this.
Our view on the current situation - 30 October
The wholesale electricity market is in a period of high spot prices, which started at the beginning of October. The industry can manage through this, as it has in the past.
Spot prices are high due to a double whammy of lower than normal lake levels and reduced gas production. These high prices are a signal to the market that fuel is constrained.
This level of pricing is not unprecedented but is unusual given the timing. The average wholesale price for most of October was $300 per MWh compared to the previous highest October monthly average1 price of $102. Prices around current levels are more common during winter months in unusually dry years.
Lake levels have been below average for this time of year since late winter. They are often reasonably low this time of year, but storage has been falling for some months due to low inflows - so they are now in the lowest 10 percent of historic storage levels. Usually when lake storage is low generators look to run thermal plant.
At the same time there have been restrictions on gas production due to equipment problems in the Pohokura gas field since late September. We understand these could persist until late November. Kupe, another gas field, is due for inspection next month and this will reduce gas output from this source.
As a result of these constrained supply conditions thermal generators are running far less than we would expect given the price. Currently thermal is only running at 40 percent of its potential, compared to last winter when we saw similar prices but with thermal running at 80 percent.
From a demand perspective, we see that consumption of electricity is trending down as we move towards summer, as it usually does this time of year.
Chart showing the seasonal demand pattern
The situation has also meant more price volatility and large increases in near-term hedge prices. This has led to spreads in the ASX futures market widening in the same way as they did in winter 2017. As a consequence trading volumes are down. However, we found in our review of the winter 2017 that purchasers exposed to the spot price bought hedges (a type of insurance) well in advance. While we are concerned at the performance of the current spreads on the ASX, the impacts are likely to have been mitigated, to varying degrees, by purchasers buying hedge cover in advance.
We understand spreads can go beyond the five percent threshold in times of stress and that their agreements allow for this. But we believe more can be done to develop the hedge market and are committed to working with industry and the ASX to improve its usefulness as a risk management tool.

What we’re doing in response
The Authority is monitoring the situation closely and our view is the market is responding as we would expect, given the fuel constraints.
As with any significant market event, we're reviewing the situation and are asking questions of industry. Some of the things we look at daily include the spot market offers, thermal generation patterns, outages, behaviour in the hedge market and hydro inflows. We’re also noting and responding to claims in the media where we find they are misleading consumers and the public.
We’re aware of concerns being raised by some industry participants about market behaviour. We take these seriously and look into them. At this point we have not detected evidence of suspicious behaviour.
We’re well prepared for situations like this and have long had regulations in place to ensure companies understand, plan for and manage risk.
We have a mandatory stress testing regime in place. This requires companies trading on the wholesale market to model their financial resilience under two scenarios. This means undertake quarterly tests to help them understand the impact high prices can have on their business. The scenarios cover off a one-off daily spike as well as sustained high prices and the results provide these companies with good information to take appropriate action. They must assure us their board has considered the results of the tests. Large businesses buying directly from the wholesale market also do stress testing to ensure they are aware of the spot market risk they are taking.
As a result of sustained high prices at an unexpected time of year, there may be companies who experience stress. Again, the Authority has a process to minimize any disruption to consumers if a retailer defaults.
Both our work on developing the hedge market and the stress testing regime are based on the belief that the industry are best placed to manage their own risk. To facilitate this we develop the tools and provide transparent information to assist companies to assess the risk and undertake appropriate actions for their business.
In spot markets, consumers benefit from low prices but are similarly exposed to the risk of higher prices – it’s up to them to choose what kind of plan is best for them.
We are focused on ensuring spot price retailers are effective in informing their customers about the benefits and risks of being exposed to fluctuating prices. As part of this, we provide and promote guidance on our website to help current and potential customers understand more about spot pricing.
Only around 1 per cent of New Zealand households are on spot-price electricity contracts.
1Compared to the previous highest monthly average for October (since 2010) of $102, which was in 2011. (The previous highest month was March 2013 at $162 average across the month.) Note that the 2018 figure is only for part of the month and it could still change

Our People Series - Julia Hall
Designing and operating New Zealand’s electricity system takes great people. In this series, we shine a light on a selection of our staff members. This month we spoke to Julia Hall from the Market Monitoring team.
On weekends you’ll find Julia Hall hurtling through the hills of Wellington on her mountain bike or exploring trails around the country. But come Monday to Friday, you’ll find her knee-deep in data, keeping an eye on the electricity market.
As a Senior Economist, Julia is part of the Market Monitoring team who are responsible for carrying out post implementation reviews − evaluating an initiative the Authority has implemented against its expected outcomes. From the Authority’s perspective, this enables learning about how regulatory decisions are affecting the sector and whether further policy action is required.
A typical day for Julia can involve everything from writing code to analysing data, reading background material (such as consultation papers and submissions) or reading about what other countries have done. She might also get the opportunity to speak to industry players about how certain changes have affected them – an aspect of the job she thoroughly enjoys.
“It’s really interesting talking to different people in the industry, getting their thoughts on how it’s working for them,” she says. “I’ve also been reading a lot about what other countries have done − or have tried to do − in the space.”
The most rewarding part of the job for Julia is seeing all the hard work pay off when a review is published. Recently she worked on the Post implementation review of dispatchable demand − a project that went live in 2014.
When asked what led her to the role at the Authority, Julia says it was all down to “a bit of luck”.
“A friend of mine actually had this role before me so when they left they encouraged me to apply,” she says. “I was drawn to the problem-solving aspects − figuring out how something is working in practice − and of course learning new stuff. I also liked the idea of working in a smaller organisation.”
Previously Julia has worked at larger organisations such as The Treasury and Statistics NZ. She joined The Treasury as a researcher when she was fresh out of university. Just over two years later she moved to London for her OE, but not before a quick stop in Hong Kong to play in the Oceania Korfball Champs.
Korfball (a ball sport similar to basketball and netball) was a big part of Julia’s life while she lived overseas for 6 ½ years. Work-wise, she spent time at a marketing consultancy firm and then moved to a role at the National Centre for Social Research. There she helped with the sample design and weighting for large-scale social surveys.
Back in New Zealand Julia spent 4 ½ years in the methodology team at Statistics NZ and then joined the Authority just over a year ago. She admits it’s been challenging getting her head around some complex issues in the electricity industry. But knowing her work can make a difference to everyone in some way − because everyone uses electricity − is gratifying.
Outside work, Julia enjoys mountain biking, an interest shared by many across the Authority.
“When I moved back to New Zealand I took up mountain biking − my dad got me into it − and now that’s about all I do. I also volunteer as a ride guide for the Wellington women’s mountain bike club Revolve.”

2017/18 Annual Report released
We have published our Annual Report for the 2017/18 financial year, highlighting our key achievements in promoting a competitive, reliable and efficient electricity market.
It was another record breaking year for consumer choice in 2017/18 as New Zealanders continue to benefit from a competitive electricity market.
- As at June 2018, there were 52 retail brands supplying New Zealand households (compared to 40 the year prior). The more brands that consumers can choose from, the harder those brands have to compete with each other.
- We closed out 2017 with 439,689 New Zealanders switching electricity companies, beating the previous record of 417,639 set in 2015 by more than five per cent.
We have seen improved efficiency and reliability in the market as New Zealand’s electricity industry effectively managed another dry winter.
- This last winter was one of the driest on record for the Southern hydro lakes, and the industry managed the challenge without it impacting significantly on household consumers. Our Winter 2017 review (published in June 2018) showed regulatory and market mechanisms successfully maintained security of supply. The biggest contribution to the effective management of dry winters has come from clear rules about when an official conservation campaign would be run and a stress-testing regime that ensure major retailers and users of electricity are aware of the risks they face.
We continued on our work to promote greater innovation and participation in the electricity sector.
- We consulted with stakeholders on what may prevent ‘mass participation’ in the electricity market. Submissions indicated that equal access to monopoly distribution networks – that is, allowing more parties to use electricity networks to exchange products and services – is a key concern for parties using or wanting to use the distribution network, particularly those interested in innovation and evolving technologies.
- We consulted on a project about barriers to consumers entering into multiple trading relationships. At present, the market rules and industry practices limit consumers’ ability to establish relationships with more than one electricity services provider. But the electricity world is changing and, as an example, we’re seeing more consumers choosing to generate their own electricity and exploring the potential for battery storage. We have signalled we may look to change the rules over the coming year.
- We collaborated with NZ power provider Mercury to assess whether there were any barriers in the Code (the electricity rulebook) that would prevent them using a battery storage facility in the wholesale market. Storing electricity directly from the national grid in a battery is a first for New Zealand.
We launched the Electricity Education Portal, the first of its kind, as part of our work to improve information availability for new entrants and participants.
- The new tool saves time for anyone wanting to find our guidelines by putting the information they need at their fingertips. Initial feedback from our stakeholders has been extremely positive and since it was launched in June 2018 there have been almost 900 users of the new tool.
As part of our work to improve the hedge market we expanded the financial transmission right (FTR) products to include three additional hubs in Kikawa, Redclyffe and Whakamaru.
- The addition of the new FTR hubs has the potential to increase competition in the retail market by allowing more small and medium retailers to enter the market in areas outside where they buy their hedge products.

Six-monthly power market review
A review of power market trends, January to June 2018
The Electricity Authority says results for the first six months of 2018 show New Zealand households are continuing to get more choice of power supplier.
The Authority’s Market Performance team keep an eye on several measures that show what is happening for consumers and enable the Authority to see what is working well and where things can be improved.
Our six-monthly health check of the market shows consumers are benefitting from a market that is open to new power companies or brands. Our analysts look particularly at the structure, conduct and performance of the market, using a range of measures.
There were 34 power companies servicing residential consumers at the end of June 2018.
A key measure of market structure is the Herfindahl-Hirschman Index (or HHI), which is based on retailers’ share of consumer accounts. A reducing number indicates more companies taking market share, which improves the competitive environment for all consumers. The HHI for the New Zealand residential retail electricity market has continued a significant downward trend during the first half of 2018. It has been going downward since at least 2008, and in a decade it more than halved, from 5509 on 30 June 2008 to 2463 on 30 June 2017. (See the graph below.)
The number of customers changing suppliers tends to be higher in winter months, and more than 40,000 consumers switched in June 2018. New, smaller retailers have been gaining market share while long-standing, larger companies have tended to drop slightly.
The Authority also monitors power company conduct to see if they are competing strongly, and one key measure is surveying consumers to find out how often they have been approached by retailers. The latest consumer survey, done in August 2018, shows more than half of households (57 per cent) have been approached about switching in the previous two years. This is very close to the 2016 survey result (56 per cent).
The team assesses how well the market is performing in delivering value for consumers. The most useful overall measure of electricity prices actually paid by households is the sales-based residential electricity cost data from the Ministry of Business, Innovation and Employment (MBIE). MBIE figures show the energy component of the cost of power to households (the part that the Authority regulates) fell by an average of 0.7 per cent during the year to March 2018. That now makes it two out of the last three years that the nominal energy costs (that is, excluding distribution costs) to residential consumers have fallen. However, due to an increase in average distribution costs (up 2.9 per cent) in the year to March 2018, the average combined cost for delivered energy increased 0.8 per cent.
Also, our statistics show demand for electricity was slightly up in most months of the past half-year compared to the past 10-year average. But overall, the level of demand is still relatively static.

Telling New Zealand's electricity story
We have released new and refreshed materials aimed at increasing consumer awareness and understanding of key concepts in the electricity industry. These materials are designed to explain the industry in simple terms and demystify complexity.
A key part of our function is to monitor, inform and educate; this includes making information available and accessible. Improving awareness and understanding of how electricity markets work is vital to help consumers understand how to participate in markets and the choices they have available to them.
Our What’s My Number campaign has proven to be an excellent way of raising awareness about competition in the retail sector, and motivating consumers to take action to check they are on the best deal for their situation.
In addition to running the campaign, we regularly publish Plain English articles in our Market Commentary newsletter, through the media and on the consumer pages of our website. These articles, publications and stories try to simplify key rules and concepts about the electricity systems, markets and rules and make them relevant to everyday consumers in New Zealand.
As more people begin to interact and engage with electricity systems and markets in more complex ways, it’s only natural that we are seeing more people taking an interest in our work. In fact, the amount of visitors to the consumer pages of our website increased by 200 per cent over the last financial year. And we know more people want to be communicated with through different mediums outside traditional text. By combining text, visual aids and good design, we can reach and improve understanding of complex information with a wider range of people.
In 2017 we created a video animation alongside the release of our Statement of Intent 2017–2021 to help inform a broader, non-sector audience about what we do and where we’re going. We tested the video with a group of non-expert consumers and 89 per cent agreed that video was a good way for us to communicate with them. This animation continues to be the most watched video on the Authority’s YouTube channel.
Since receiving this feedback, we have been working on creating a short series of videos to explain key areas of the electricity industry and topics where we receive the most enquiries and see the most misunderstanding. This first video aims to explain how electricity flows and the key parts that make up electricity pricing in New Zealand, including the average proportion that relates to generation, transmission, distribution and retail.
We have updated our flagship publication, Electricity in New Zealand. This popular resource is used to increase public and consumer awareness, and understanding of key concepts in the electricity industry.
Schools, new entrants to the electricity sector, customer service staff and consumers, find this resource very valuable. It explains what distribution, transmission, and generation companies do, and the marketplaces where electricity is traded. It also includes some great facts about electricity history as well as graphs, examples and infographics to bring the information to life.
If you know others who would be interested in finding out more, please encourage them to subscribe to our Market Commentary newsletter, visit our consumer web pages and follow our Twitter, YouTube and LinkedIn accounts.
If you’d like to receive hard copies of Electricity in New Zealand or want to know more about our consumer materials, email us at: email@example.com.

Participation of battery storage units in the wholesale market
The Authority has a project underway focused on the Participation of new generating technologies in the wholesale market. It will investigate and address any barriers in the Code (the electricity rulebook) to the efficient operation of new generating technologies, like batteries, in the wholesale electricity market for energy and ancillary services.
The Authority has also considered a specific proposal by Mercury for the integration of the first battery directly connected to the high voltage national transmission grid. The Authority was satisfied that there were no barriers in the Electricity Industry Participation Code 2010 (Code) that prevented Mercury from implementing its proposal.
Storing electricity directly from the national grid in a battery is a first for New Zealand. The electricity stored in the battery will then be traded on both the wholesale energy and instantaneous reserve markets.
The benefits of any future batteries could also be achieved by connecting to a local network rather than the national grid.
Electricity Authority Senior Advisor Wholesale Markets Mike Collis says, “We are striving to develop regulatory systems able to be flexible and innovate quickly to ensure consumers’ benefit from the efficient operation of new storage technologies in the wholesale market.
“The Authority encourages Transpower and distributors to adopt approaches that allow those providing innovative services from devices such as batteries, to access their networks on a non-discriminatory basis.”
In the future, consumers will have greater opportunities and choices to enjoy the benefits of the new technologies becoming available.
Removing barriers to different forms of generating technologies in the wholesale market will improve supply side competition, contribute to reliability and potentially improve the operational efficiency of the electricity industry.
Mr Collis says, “The Electricity Authority wants to see households, and commercial and industrial consumers, enjoy the benefits of greater choice.
“The battery will also have benefits for the consumer by helping meeting peak demand, and will complement New Zealand’s existing storage in hydro lakes as well as enhancing security of supply to Auckland.”
The battery, at Southdown in Auckland, provides an opportunity to research the integration of battery technology into New Zealand’s electricity system.
The battery is modular and fully scalable. The Southdown site and grid connection has the capability to ultimately deliver 100+ MW of battery-stored power into the national grid, supporting national security of supply.
Mercury will be holding a battery launch event at Southdown on Wednesday, 22 August and the Minister of Energy and Resources, Hon Dr Megan Woods has confirmed her attendance along with key electricity industry participants.

Our People Series - Chris Otton
Designing and operating New Zealand’s electricity system takes great people. In this edition of Our People, we shine a light on Chris Otton from the Wholesale Team.
The Authority has turned out to be an ideal place for Chris to put his background in applied physics, love of problem solving and strong interest in the wholesale electricity market into action.
As an adviser in the Wholesale Markets Team, Chris provides expert advice and analysis on developing the wholesale market including the primary spot market, the secondary hedge market and ancillary service markets.
When he’s not busy providing subject matter expertise on the Extended reserve implementation project he uses his wide industry experience to support other advisers on their projects. He enjoys helping out and providing input to the Authority's wider work programme where needed.
Chris was drawn to the role at the Authority because he wanted to get back into the area of wholesale markets, after working in other areas of the electricity sector.
Chris started his career in the NZ electricity sector as a market services analyst at the system operator (Transpower). The main focus of his role was managing and monitoring ancillary services provision and developing system operator’s data storage and reporting capabilities.
Before joining the Authority in August 2017, Chris worked for Contact Energy, first as a spot trader and then in business performance. In the spot trader role he focused on the week ahead trading strategy—looking at plant and fuel availability, market conditions and financial priorities, and then set a broad strategy for the real time traders to implement.
Chris Otton says, “I enjoyed the detail involved in working in the spot market. It was a real problem solving role with many moving parts.”
But a career highlight for Chris came while working for the system operator during the commissioning of HVDC pole 3 in 2013. During this time, he managed the Market Contracting Team.
Mr Otton says, “The commissioning period was a dynamic time—trying to figure out what we needed from the participants to achieve the testing conditions for the engineers, while trying to make sure we could achieve it at a reasonable cost.
“I really enjoyed working to tight deadlines, leading a team of very engaged and professional people.”
Lucky for Chris, he is also surrounded by talented and engaged people at the Authority who like himself are keenly interested in what they do to develop the electricity sector.
Mr Otton says, “Moving into a regulatory environment has been a big change for me but I’ve found everyone at the Authority to be very supportive and more than willing to share their experience. It’s great to be working with such a passionate and knowledgeable group.”

Our 2018/19 Work Programme and strategy documents
We have recently published our 2018/19 Work Programme along with the Statement of Performance Expectations (SPE) on our website. The Authority’s work programme details the major strategic projects we intend to progress during the 2018/19 financial year.
To remain responsive to changes in our operating environment, we review the focus of our work programme each year.
The work programme makes a significant contribution to achieving our strategic objectives, as set out within the 2017-21 Statement of Intent. We then set out in the SPE how our work for the coming year is expected to contribute to achieving our strategic objectives.
After taking on-board stakeholder feedback, we are more focused on delivering our priority projects faster, so consumers can benefit sooner. We are confident that by doing fewer projects each year we will achieve more overall.
A key component of our strategy is the removal of inefficient barriers for companies wishing to use new technologies or business models to offer new products and services to residential and commercial consumers.
Two of our priority projects are focused on addressing inefficient barriers: The Equal Access project is focused on addressing inefficient barriers to the ‘poles and wires’ that electricity networks use to transport electricity. The Multiple Trading Relationships project is focussed on inefficient barriers to consumer’s ability to establish relationships with more than one electricity services provider.
Our work to improve price signals represents another key component of our strategy. When parties can see the real distribution and transmission costs of their decisions, they are more likely to adopt the most appropriate technologies for their circumstances. We want improved price signals so that consumers and participants can make more efficient operational and investment decisions.
To find out more about our work programme and our priority projects go to the ‘About us’ section of our website.
We value our stakeholders’ feedback. Don’t hesitate to get in contact to find out more about our work.

New Electricity Education Portal a first for the energy sector in New Zealand
A new online Electricity Education Portal tool was launched in June, to help new and existing electricity market participants find key information more easily. It also helps participants interact with each other, the regulator and the market.
The portal shows the relationships between hundreds of different topics and knowledge areas within the industry’s guidelines. It’s aimed at anyone with a desire to understand how the electricity system works.
As part of his role as Principal Advisor Market Services, Ron Beatty, works with new entrants to the electricity sector.
“A couple of years ago we had been considering ways of better presenting information and we were shown some new visualisation software,” says Mr Beatty.
“It was immediately apparent to me that we could enhance the guidelines with this type of software. It fixed a lot of issues we knew we had with presenting information to participants in an integrated manner.”
Data visualisation software has been applied to electricity sector guidelines to present information in an easily accessible format. Users who are looking for more in-depth information can follow links to find as much detail as they need.
The tool focuses on the relationships between hundreds of different topics and knowledge areas within the guidelines. It is like a three dimensional neural network.
Mr Beatty says, “There is so much development going on worldwide in technology that is being applied in the electricity industry. There is a lot to keep up with. With over four decades’ experience, I am still learning.
“It’s very important that participants like retailers and generators, networks and metering equipment providers, understand the role they play within the market.
“If, for example, you are retailer new to the sector, you can search on a specific topic, or you can follow the Use Cases as a learning scenario, to find out about the framework that you must operate within (Electricity Industry Participation Code 2010), and what your obligations are to the electricity market.”
The Code talks about obligations and outcomes, but doesn’t show participants the linkages that they need to understand to make their obligations work. The Portal saves time for anyone wanting to find our guidelines by putting the information they need at their fingertips.
Whiteboard Energy and the Authority have worked collaboratively to produce this portal which can be viewed here. This information will continue to be developed going forward. What you see now is the starting point.
To assist you to use the portal we have developed a user guide and video.

Snapshot of the retail electricity market
We have released a new interactive tool to highlight key changes in the retail electricity market. Users can interact with information in the Retail market snapshot and see how the market has evolved over time.
The new interactive Retail market snapshot tool uses Tableau software to summarise key information on switching, market size and share, market concentration, consumer choice, smart meter deployment and solar generation. Users can engage and interact with the information and easily see year-on-year comparisons.
The tool is directly linked to the Electricity Market Information (EMI) website for anyone who wants to drill into the information in more depth.
New Zealanders continue to enjoy a highly competitive retail electricity market. In 2017 we saw small and medium retailer growth, a continuing uptake of new technology and the highest rate of switching on record.
Consumer choice at new high
At the end of 2017, residential electricity consumers had a choice of between 12 and 35 retail brands depending on where they live. This is a new high. Having new brands and options come into the market pushing existing retailers to create new and innovative offerings is an indicator of healthy competition. Consumers are responding to the choice by switching electricity providers at record rates. 2017 had the highest rate of switching on record with 439,720 consumers switching. Otago was the region with the highest switching rate. In total, 23.4 per cent of Otago consumer connections switched retailers in 2017.
Small and medium retailers continue to grow
The growth of small and medium-sized retailers continued in 2017 with new entrants entering the market and competing for customers. In 2017 small and medium retailers supplied 11.1 per cent of consumer connections, up 1.7 per cent from 9.4 per cent in 2016. Electric Kiwi increased the number of connections they supply the most in 2017, gaining an additional 12,239 customers across New Zealand.
Smart meter deployment continues
Installations with smart meters continued to increase in 2017. At the end of 2017, 81.1 per cent of residential consumer connections had a smart meter, 4.4 per cent more than in 2016. Smart metering technology lowers the cost of collecting meter readings and provides access to more detailed information on consumption. More importantly, smart meters allow retailers to design more innovative and tailored offerings to consumers.
Users looking for more in-depth insights can hover over each section in the tool and follow the link to the corresponding EMI report. The EMI website allows users to customise content and visualise New Zealand electricity market information in dashboards and reports as charts, maps and tables. Users can also create their own dashboards allowing them to capture content that they want to return to keeping it in one easy-to-access place.

The electricity sector is on the cusp of transformation
Electricity Authority’s Manager Retail and Network Markets Craig Evans, outlines the exciting and ever changing environment of the electricity sector and the work the Authority is undertaking to reduce barriers to participation.
The changes are underway now, and in the future consumers will have greater opportunities and choices. Electric vehicles, energy management systems, solar panels and batteries are giving consumers more choice about how they use electricity and where they get it from.
Mr Evans says, “We think the New Zealand electricity sector is well placed for consumers to enjoy the benefits of the new technologies becoming available.”
The Electricity Authority wants to see households, and commercial and industrial consumers, enjoy the benefits of greater choice.
Consumers’ and suppliers’ ability to participate depends on their ability to get access to services.
Adjusting to New Zealand’s electricity future involves three factors that need to be considered to promote increased participation:
- the physical platform, for example the poles and wires used to transport and distribute electricity across the country,
- the market system – how electricity is bought and sold, and
- suppliers of services, for example P2Power which matches people with local generation (eg solar) selling to their neighbours.
Facilitating innovation and participation is a key focus of the Electricity Authority’s work along with reducing barriers to the entry, expansion, and exit, of parties in electricity markets. Craig Evans’ role within the Market Design team is to progress a number of projects in these areas.
“We have several projects looking at barriers to accessing services, such as the Equal Access and Default distributor agreement projects. A particular focus is the relationship between distributors and parties using the distribution network, because most of the changes to the sector are occurring at the consumer and distribution level,” says Mr Evans.
Craig Evans’ team are looking at data flows – “there’s a lot of data behind the scenes in New Zealand’s electricity system. We want to see that data is exchanged between participants across the supply chain.” The Multiple Trading Relationships project is examining concerns related to possible barriers to parties providing services to consumers, such as obtaining data.
They are also investigating pricing – “this is about the prices of the bundle of services needed to get electricity to the consumer better reflecting the cost of supplying each service,” says Mr Evans.
“Our Distribution Pricing project is about encouraging distributors to adopt prices that provide parties using the distribution network with the best possible information about the value and cost of using the network at a particular time and place.”
The Electricity Authority, with the Commerce Commission, are working hard to find and reduce unnecessary barriers to more participation and to consumers enjoying the long-term benefits of the changes occurring around us now.
The Authority’s work feeds into making recommendations for regulatory change.
