News & Updates

A love letter to electrification this week as a kea soars high on solar, more electric buses for Auckland (and more Rivian vans for businesses), longer lasting EV batteries, more solar on smart schools, an open letter to the Australian Government asking for 'Real Zero' not net zero, and the world's first electric snowbike.

As Rewiring Aotearoa’s Electric Homes research has shown, New Zealand has already reached the electrification tipping point, so going electric and running your home and car with a combination of grid electricity and rooftop solar and batteries is already a good economic decision for most homes (and likely the best thing they can do to reduce emissions). But, as Newsroom's Marc Daalder writes about the Energy Competition Taskforce proposals (paywalled), "proposed changes to the electricity market could see Kiwis paid more for the solar power they export to the grid, and less when drawing from the grid at off-peak times".
"I firmly believe electricity is the next crop for farmers in New Zealand, and the more farmers that get involved in this, the better the returns for farmers are going to be ... My big dream is that farmers start powering New Zealand. That would be really cool." Seven Sharp ventured to Cromwell recently and Rachel Parkin put together a beautiful story about the all-electric Forest Lodge Orchard. The team has proven that it's possible to grow cherries without burning any diesel on the farm - 'not a single drop,' as manager Euan White says - and that farmers can play a role in the energy system by generating, using, storing and exporting their own electricity. At the moment, many homes, farms and businesses are reliant on expensive molecules sent to us from the other side of the world. Fossil fuels have taken us a long way, but there is a better and cheaper option: locally-produced electrons. That's good for businesses, and good for the country as a whole. Watch the show on TVNZ+ (skip to 4 mins).
Fully Charged, which has a large global reach and claims to be the world's number one home energy and electric vehicle channel, came to visit Mike Casey at the all-electric Forest Lodge recently. As host Robert Llewellyn (who Red Dwarf fans may recognise) says: "I think this is a shining example of what can be done today and what should be be done, particularly for countries like New Zealand that have to import their fossil fuels from a long, long way away".

RNZ's Susan Edmunds reports on the Energy Competition Taskforce proposals and says the changes "should lead to New Zealanders with solar power systems on their houses get more of a return for any power they put back into the system". As Electricity Authority chair Anna Kominik says: "New Zealand's electricity market currently relies on a few big generators to supply electricity at select locations and transmit it to households and businesses across the country. But as uptake of solar and battery systems continues to increase, more consumers will be able to contribute to our electricity system. And as smart electronics and vehicles become more ubiquitous, consumers will also be able to more actively manage their own energy use and costs. We're proposing three changes to help support this consumer empowerment and decentralisation of our energy system. Over time, this will increase community resilience and lower power costs for everyone," she said.
Homeowners with solar panels and batteries installed could be paid more to sell electricity back to the grid, reports TVNZ's Jessica Roden following the release of the Energy Competition Taskforce proposals. As Nelson solar installer Jon Pirie says in the piece, perfectly illustrating the 'neighbourhood effect', "year over year, people are more interested. They see the power bills going down and next thing the neighbours have got solar." Mike Casey also appears in the story saying anything we can do to incentivise customers to install their own generation and storage will help create the cheapest energy system.

Rewiring Aotearoa's response to the Energy Competition Taskforce: a pat on the back for recognising the shift and focusing on the role customers are playing - and will play - in the energy system, but just a light pat because more could be done to ensure the proposals are followed through on.
We're definitely not running on fumes this week ... Why our electric future - from e-bikes to e-boats - looks both fun and functional, why swapping fuel for finance is crucial for homeowners (and access to capital is crucial for businesses like Chargenet that are helping to speed up the transition), how renewable energy projects are helping developing countries and low-income communities, and an ad from 1929 that reminds us of something.
Stuff's Kylie Klein Nixon showcases the many benefits of Carl Hamlin's electric new build, which includes a hot water heat pump and solar panels. As the story says: "Water heating comprises about 1/3 of a household’s energy use, [EECA's Gareth] Gretton says. Hot water systems have a 15-year life expectancy, and 46% of hot water systems in New Zealand are over 10 years old. When we do replace old hot water systems, there is a tendency to replace like-for-like." Gas is the most expensive, hot water heat pumps have the lowest running costs and you're likely to make the most savings by electrifying your vehicle. If you want to save cash and slash emissions, your next purchasing decision should be electric.

The most important energy cost is not what a corporation pays to produce or generate it, but what a consumer pays to buy it. That’s why Mike Casey argues the delivered cost of rooftop solar and batteries – and the other benefits these technologies provide to the system – need to be factored in when making investment decisions.

New suburb-wide electrification pilot projects set to kick off in Australia, Fonterra's electrification plan to upgrade its boilers and trial EV tankers, Napier EV charging business Kwetta eyes up global expansion, Uber CEO Dara Khosrowshahi talks about the massive rise of electric taxis, the German balcony solar movement spreads into Spain, and what if fossil fuel cars were the new technology?
The Post's Alka Prasad has gone deep into how farmers are electrifying their operations, installing solar and batteries to alleviate concerns about dry years, and reducing their energy costs. As Maniototo farmer and owner of Solayer Becks Smith says in the story: "It's not an either-or situation from hydro-generated electricity to solar-generated electricity. It's about having a renewable electricity grid and shifting as far from fossil-fuel energy as we can,” she says. “For business resilience, the energy you can generate and use yourself is the cheapest energy you'll ever get." Rewiring Aotearoa CEO and electric orchardist Mike Casey says "farmers could have a huge positive influence on New Zealand's electricity system by generating power themselves and putting it into the grid for everybody else to be able to heat their homes, heat their water and charge their electric vehicles". "We can treat our hydropower scheme more like a battery which could power our homes and businesses at night time and solar can do a lot of the grunt work during the day,” he adds.
PV Magazine picks up Mike Casey's opinion piece on the need to level the playing field for customers with rooftop solar and batteries.
Some big switch energy this week as solar panels go vertical on farms (and on fences), induction disappears in fancy kitchens and celebrity chefs move towards the magnets, Counties Energy pushes a vision of the future that we can get behind, Bunnings spots a trend and launches a new range of EV charging products, and a brilliant game created to annoy asset managers investing in fossil fuels.

Writing in Newsroom, Rewiring Aotearoa CEO Mike Casey looks at what's holding New Zealanders back from buying EVs despite the many benefits and why this technological shift is inevitable. "Incumbents always try to cling on, but the horse and cart is now a novelty, as is the landline, the fax machine and the Blackberry. These technologies served us well at the time, but they have been usurped and my prediction is that petrol and diesel vehicles are next."

In need of some good climate news? Writing in the NZ Herald, Simon Wilson has compiled a list of New Zealand entrepreneurs and innovators, including Rewiring Aotearoa CEO and 'electric orchardist' Mike Casey, who are pushing things in a more positive direction. We need action across the board if we have any hope of reaching our climate targets, but energy is one area where positivity is warranted because the costs of renewables and electric machines continue to drop. At Rewiring Aotearoa we believe electrifying our homes, vehicles, farms and businesses will save us all money and help us address climate change. So let's embrace that win-win.
Mike Casey talks to Jamie McKay on The Country about the current cherry market, what's happening with EVs, why investing in solar can help reduce energy farmers' costs and his plans for 2025.
New research from Rewiring America explores homeowner awareness and motivations for making the switch from fossil fuels to electric - and offer some helpful guidance for anyone looking to convince New Zealand homeowners to go electric.

We're getting high on electrons this week as aviation goes electric in New Zealand and around the world, the rise of the anti Elon Tesla Club, how Toyota could be the next Kodak after ignoring the rise of EVs, inside the struggle of a family-owned oil company and more marae add solar and batteries to prepare for emergencies.
Drive Electric chair Kirsten Corson explains the significant reduction in lifetime costs from buying an EV compared to signing up for an expensive and unpredictable petrol or diesel subscription.

Read moreShareable linkDownloadWhile the potential implications of the Bill are wide-ranging, our submission has focused on the potential implications for the electrification of Aotearoa NZ if the Bill is enacted as proposed. This is pertinent to Rewiring’s work, because one of our core aims is to help reduce energy bills for customers - NZ’s households, farms, and businesses. Significant changes are needed to fix the status quo, and we are concerned that the Bill may inadvertently bake in the existing rules governing the sector.

These guidelines can provide a consolidated and trusted source of information to help households navigate the process of choosing and installing solar PV and batteries. There is some messaging and information in the PAS that we think needs to be changed or added to provide households with the best advice to support them to maximise benefits from solar PV and batteries. This includes removing the focus on pay back periods and informing households about cost savings from day one from solar PV and batteries financed over the life of the system. Households also need information about the potential risks of some existing lease to own sales models which provide little real benefit to households with the bulk of the savings captured in suppliers profits.

We agree that simplifying and streamlining the procurement process is important, and reducing rules is a logical starting point. However, this should not undermine key considerations and past efforts in ensuring government spending supports long-term positive outcomes. Government procurement can support us to go for growth by increasing productivity of energy, which is a fundamental economic input
Read moreShareable linkDownloadOverall, Rewiring Aotearoa welcomes the objectives of this package of proposals. from the Energy Competition Task Force. We view the package as a critical step in improving energy system outcomes for all consumers. We consider retailers paying consumers fairly as a critical step, and we are mostly satisfied with the Task Force’s approach to this (initiative 2C) and think it will create better outcomes for New Zealand consumers and the energy system as a whole. In contrast, the Task Force’s preferred option around how distributors are required to reward peak input from consumers (initiative 2A) will not in our view meet the Task Force’s (or the Electricity Authority’s) stated objectives.

Read moreShareable linkDownloadRakiura / Stewart Island faces the highest electricity prices in New Zealand. Successive governments have funded report after report and numerous fly-in visits by Ministers have failed to change this situation for the local community. Rewiring Aotearoa believes the opportunity is to harness existing solar and battery technology to deliver significant cost-of-living savings and reduced emissions at scale via electrification on Stewart Island right now. With financed solar and batteries, electricity usage costs for residents could be halved without delay. Rewiring Aotearoa has been engaging with the local community, who have been sending us their power bills. On Saturday 27th April some of the Rewiring team visited Stewart Island (including Mike Rewi who has strong whakapapa to Stewart Island). What we are hearing from this community is many locals fear the proposals and the likely “preferred option” will be focused on replacing current diesel generators, not on reducing the cost of energy for consumers. Our proposal outlines Rewiring Aotearoa’s pitch for an alternative approach to develop a community-led energy solution for the Island.

Rewiring Aotearoa believes one such outcome from market innovation is supporting the electrification opportunity for Aotearoa New Zealand. The Commission has the opportunity to play an active role in driving this not just through the energy market, but also through the personal banking market. It is important that these functions are not seen in isolation, but as a system, to better realise the Commission's role in delivering on NZ’s emissions reduction plan, and 2050 Nationally Determined Contribution.

A new report has shown that, on average, homes currently using gas appliances and petrol vehicles could save thousands every year if they went electric and got their electricity from a combination of rooftop solar, home battery and New Zealand’s already highly renewable grid.

However, today there is a systemic bias towards traditional infrastructure largely because it is seen as significantly more ‘dependable’. There are a variety of historical reasons for this. Our primary context to this submission is that many of the assumptions and rationale for this bias are quickly falling away, and DPP4 provides a significant opportunity for the Commerce Commission (the Commission) to reset the assumptions and correct some of this bias.

The EA has the ability to take a leadership role in the energy transition on behalf of electricity consumers. Far more than the Commerce Commission’s oversight of EDBs investment plans, the EA’s network pricing workplan gives consumers agency in the development of the electricity system. When consumer agency is stifled, they will likely have significantly worse financial outcomes on their bills. Much of the necessary changes have been demonstrated already locally or overseas, and the remaining question is not if the changes are possible but if we as a nation will have the courage to implement them on the timeline required to drive better energy transition outcomes for consumers.

Read morePlenty of people need cars (and plenty of people still want them), and other vehicles are literal engines of prosperity. We don't have to give them up to reach our climate goals. We just need them to be electric.
Read moreSolar on our rooftops, farms and businesses can displace the emissions generated by burning fossil fuels in our homes and especially our cars, provide the extra electricity we need to run our electric machines, help bring the cost of electricity down for everyone on the network, and improve our energy security by keeping water in our hydro lakes for when we need it most.
Read moreWe often hear from people who aren’t sure if switching to an electric alternative is the right move. One of the most common questions we get asked is ‘will switching to an electric machine actually reduce my carbon footprint if creating the new machine or materials produces emissions?’It’s a fair question, and we completely agree it’s important to think about the full life cycle of the products we buy and use. Electric alternatives, including vehicles, often produce more emissions than fossil fuel equivalents during manufacturing. But, over the lifetime of the machine, they create much less carbon pollution because they don't burn any fuel.
Read moreFossil fuels for homes, transport and industrial processes make up the vast majority of the country’s total energy consumption. Electrifying the machines that use these fossil fuels means we will use more electricity but much less energy overall.
Read moreAn electrified energy system is actually full of opportunities for redesign, reuse, recovery and recycling. There are opportunities for innovators and entrepreneurs to generate value across the lifespan of every energy asset, not least the return of its components to the manufacturing cycle. To explore this further, Rewiring Aotearoa has partnered with Circularity, local experts in circular design and strategy, to explain what the circular economy is, how to integrate circularity into the design of energy systems, and the role of policy strategy to make it happen.
Read moreThere are no free lunches in energy. But some lunches are far, far cheaper than others. Electrifying everything will massively reduce the overall material and energy requirements of the global energy system. This can be said with high confidence. To be sure, renewable energy systems take materials and energy to build. But this is dwarfed by the mind-boggling scale of extraction, consumption and wastefulness of fossil energy.
Read morePeople sometimes talk about ‘carbon tunnel vision’ – that is, the single-minded pursuit of emission reductions at the sake of everything else. But this is the wrong way to think about electrification. It isn’t only about emissions (even though preventing the world from dangerous overheating is quite the co-benefit). It isn’t only about the tech or the kit: the rooftop solar panels, the batteries, the electrified appliances and vehicles. These are just the means to an end. Electrification is about people and it is a fundamentally better way to power our lives and livelihoods.
