A big week in the long-running battle to turn EVs into batteries on wheels, researchers prove that using cheap solar during the day to heat the water is a good idea for customers and the grid, a solar map of New Zealand that offers lot more detail, tiny turbines (and tiny homes inside massive turbines) and a flood resistant EV.
Driving it home
It’s long been a dream of EV enthusiasts for electric cars to power our homes and contribute to the grid, not just move us around and it looks like that will soon become a reality in Australia as Vehicle-to-grid (V2G) charging crossed an important regulatory hurdle this week.
This excellent ABC story runs through some of the barriers the technology has faced and the likely roll out of bi-drectional chargers that allow the transfer of electricity and, as it summarises:
In short:
Vehicle-to-grid (V2G) charging, where electric vehicles can be used to power households and export energy to the grid, has cleared an important regulatory hurdle.
The federal government says the first V2G chargers will be certified by Christmas, but industry experts say a more likely timeline is mid-2025.
What's next?
The mass uptake of V2G could reduce household energy spending and also defer the need for some big energy storage projects, but it's unclear which EV models currently on the market in Australia will support V2G next year.
New Zealand is currently looking to Australia and other trading partners to update over 400 outdated standards around solar installation and EV charging, as well as consulting on the voltage range. We’re confident it won’t be too long before this is available in New Zealand, and many of the newer EVs already come equipped with the tech required to do it.
As Saul Griffith said during his Investing in Tomorrow tour:
🚗🔋 All the electric vehicles in New Zealand will be one of the country's biggest batteries.
☀️🔌 All the rooftop solar on our homes and farms will be one of the country's biggest generators.
🏭 And, just as the hydro dams and transmission lines of the 20th Century got good deals on finance because they were seen as critical infrastructure, this growing collection of 21st Century customer assets needs to be seen as critical infrastructure, too.
As the cost of grid electricity keeps going and power bills rise next year to pay for the upgrades of our poles and wires, new technology allows savvy customers to offset some of those costs, either by producing your own or getting involved in the electricity market. This is a world we’re working towards and it will be a better world for customers.
Liquid assets
We like to do our own research at Rewiring Aotearoa (not in that way) but we also like it when others do research that backs up our view and in a real-world trial in Australia, academics have looked at whether using cheap rooftop solar during the day to heat water is a good idea.
The headline says it all, really: “If our hot water heaters ran off daytime solar, we would slash emissions and soak up cheap energy”.
“Switching water heaters to charge during the day can soak up solar power going to waste – known as curtailment – and make sure electricity supply and demand match. In our new real world trial, we put this technique to the test and found it works.”
“... As ever more renewables enter the grid and more Australian households go electric, many of us will ditch gas hot water systems. These trends mean heating water during the day will be even more valuable.”
In New Zealand, our Electric Homes report showed that heating water (which makes up around 30% of a home's energy use, not including vehicles) is cheap as chips with solar and a heat pump.
Drilling down (on solar)
Some more interesting research into solar, with Yvonne Matthews “using advanced machine learning techniques on aerial imagery to detect where solar panels have been installed in New Zealand and provide much more detailed information than the aggregated data available the EA.
This last one is what’s known as the neighbourhood effect and, as Mike Casey outlined in his latest opinion piece, “generally, we hang on to old ideas for a long time, and it basically takes someone's neighbour to do something before they adjust their views on it.”
Shoot the breeze
We talk a lot about rooftop solar, mostly because it’s the cheapest form of electricity available to New Zealand households, and how it's very different to solar farms because the delivery costs and middlemen fees are removed. So what about wind? Can we also go from just a few massive turbines to lots of small turbines?
The company behind Aeroleaf reckons it’s possible and has developed a turbine that looks like a curled leaf and are installed in groups called a ‘wind tree’ or ‘wind bush’.
“When the wind blows, it spins and generates energy that can go directly to a nearby building,” says Luc Eric Krief, CEO of a French startup called New World Wind.
Pretty clever, but, as always, it all comes down to cost. And in many cases it’s probably cheaper to get solar and a battery.
One unexpected benefit of going big is that an old turbine can be turned into a home.
Rise of the aquacar?
Sick of driving your EV on the roads? Chinese auto company BYD has you covered with the 'flood resistant' plug-in hybrid U8, which it has launched under the luxury sub-brand Yangwang.
It could be argued that modern cars are over-engineered but, as some have pointed out, floods are likely to be a more common occurrence in our hot world.
In case water resistance isn’t the main driver in your car purchasing decisions, it also has a range of other features and shows how far the Chinese EV manufacturing industry has come.
Just like flying cars, while the idea of amphibious vehicles has always been appealing, they have never really delivered.
Sorry, Aquada.
Paddy Gower recently paid Forest Lodge a visit on his national tour and Mike Casey was featured as The Brainy Kiwi. Casey explains the problem he's trying to solve and why he believes generating your own energy and using it at the source is a much better and more efficient way to run our homes and businesses.

Read moreDownloadRNZ's Kathryn Ryan has talked to energy researchers who claim rising demand for electricity in summer (largely due to increasing air conditioning requirements and EVs) will have repercussions on lake levels come next winter. And while Transpower says the risks of an electricity supply shortage this year have eased, next winter's forecast is concerning. Irrigation is also a major user of electricity in summer in some regions. Solar is well-suited to both of these cases as the electricity is usually required during the day when the sun is out, so more solar at home and on our farms can provide a lot of what we need with less strain on the grid and at the lowest cost.
As David Hasselhoff almost sang, jump in my much cheaper and increasingly popular electric car and see why 96% of EV owners would buy a second one; the UK's last coal-fired electricity plant is switched off; the IEA's renewables report makes for good reading; a Rivian takes an unexpected trip down a river; and comedian Tim Robinson gives some helpful advice to climate change communicators.

Read moreDownloadMike Casey learned about the difference between planting carbon-sucking trees and avoiding carbon-emitting diesel when he was setting up his Central Otago cherry orchard. As he writes in The Spinoff, seeing this laid out was something of an 'emissions epiphany' and showed he had good intentions but was focusing on the wrong thing. He believes "many New Zealanders are also focusing on the wrong thing and could do with an emissions epiphany of their own". Electrifying your car, cooktop, water heater and space heater and powering them with renewable energy from rooftop solar, home battery and the grid is likely to have the biggest impact on your emissions tally. And, by comparing these 'dinner table decisions' with return flights between Queenstown and Auckland, the piece shows that substitution is often more effective than sacrifice.

Danyl McLauchlan's latest column (paywalled) in The Listener examines what's stopping that opportunity from being realised (hint: incumbent interests and a profitable status quo being protected by industry lobbyists "swarming the Beehive like flies around a dead cat"). As he writes: "Eventually, someone will have to notice tens of billions of dollars lying on the ground, just waiting to be picked up – even if political expedience and ideological dogma are screaming at them to ignore it."
Read moreDownloadDr. Rajeev Shah is the president of the Rockefeller Foundation and, as world leaders gather for the United Nations General Assembly, he argues that nothing matters more to individual well-being than energy, which is what leaders need to focus on. As he writes: "Electrifying the world could produce the largest development gains since the 1990s. Electrification is about more than progress for individuals; it makes the world safer and more secure. High energy prices are straining livelihoods at a moment when coups, migration and unrest are destabilizing regions. And because the countries where energy access is lowest are projected to produce as much as 75 percent of greenhouse gas emissions by 2050, connecting people there to clean energy can help prevent climate catastrophe for us all."

Read moreDownloadFarmers stand to save money, make money and reduce emissions by adopting electric technology and powering it with solar and batteries. But, as the story in Farmers Weekly says, one sticking point for farmers is that, at present, they can’t gain the full value from rooftop solar when they have multiple connection points on one farm. Rewiring Aotearoa has called on the Government to make some regulatory changes so t farms with multiple connection points are able to group them together for billing purposes and make the most of their solar generation across the business.
Read moreDownloadLet's raise the roof! 🏠🌞 Customers with solar and batteries need to be seen as a critical part of our 21st Century energy system and academics from Auckland University of Technology agree, pointing out that the 14 biggest rooftops in Auckland would be equivalent to New Zealand’s largest solar farm. The rooftops of 167 schools and supermarkets would provide the same amount of energy, albeit much closer to the point of consumption and that's why we're arguing for a more decentralised system.

Read moreDownloadRewiring Aotearoa thinks customers need to be considered part of the energy infrastructure and three academics from AUT agree, arguing that a more decentralised system could play an important role in a more resilient system. As they say: "By focusing only on solar farms, we are using new technologies in an old-fashioned way, by centralising power generation in certain locations, in the hands of a few companies."
Read moreDownload"The only way we can begin to hedge our businesses against higher spot prices is by beginning to generate our own electricity," says Mike Casey. Read about how he hopes to turn his energy bill into a revenue stream with the help of solar and batteries that can generate electricity cheaply, and store it to sell when it's expensive.
Read moreDownloadMike Casey lays out Rewiring Aotearoa's argument for a regulatory change that would allow customers with solar and batteries to compete fairly with large generators, something we call symmetrical export tariffs. It's important to note that these are not subsidies or rebates. "They simply ensure customers get a true reflection of the value they provide to the electricity market. They are no more a rebate than the half-hourly prices in the wholesale market, paid to generators for their output ... The current pricing structure is compromising New Zealand’s delivery of a secure and affordable power system; it fails to recognise that peak demand could be reduced with the help of household batteries; it perpetuates the idea that we need to spend tens of billions to upgrade our poles and wires to cope with that peak demand; and it is stifling demand for solar and batteries among New Zealanders because their true value is not being accurately reflected in the price paid for export."
Read moreDownloadThe recently announced Energy Competition Taskforce has announced "two packages of work that collectively aim to encourage investment in new generation, bolster competition and provide more opportunities for consumers to manage their own electricity use and costs" and said it is "serious about creating change". Of particular interest to Rewiring Aotearoa was the section about better rewarding customers to "encourage greater uptake of things like time-of-use pricing plans, rooftop solar and batteries, and demand response by industrial firms," as EA chair Anna Kominik said in a press release. This is positive and aligns with what we've been asking for and what we outlined in our symmetrical export tariffs paper, but it is important to note that these are not rebates. This is just cost-reflective two-way pricing that levels the playing field between small and large generators. As Rewiring Aotearoa CEO Mike Casey says: "To date, every home giving energy back has been getting a bad deal. We believe their contribution to the system should be accurately priced and, as we said when the taskforce was announced, we want a level playing field, not just a slightly less uneven playing field." Casey says this pricing also needs to be mandatory otherwise the EA risks further delay to keeping bills down and building a more secure and resilient energy system. "We talk about guaranteeing investment signals on the big end of town. How about the average Kiwi got some guaranteed investment signals that are fair?"

He talks to Dr Saul Griffith about the savings at a household level, the $29 million a day electrification opportunity for the country as a whole, the economic slam dunk of rooftop solar and why the Government should be looking to give favourable finance to customers who can become part of our energy infrastructure.
Read moreDownloadOne News has covered the Investing in Tomorrow report, which shows that big household savings from electrification add up to big national savings. As Dr Saul Griffith says about the $29 million day that New Zealand could save if we swapped out fossil fuel machines for electric equivalents and ran them off renewable electricity from the grid, rooftop solar and batteries: "It's nice to be able to make the carrot that large because I think it focuses the policy mind on how to get there."

As it summarises: "Saul Griffith helped change the world a couple of years ago when he and a couple of "tech bro" mates convinced Joe Biden to rewrite the Democrats’ Green New Deal and pitch it as an Inflation Reduction Act to rewire America’s economy with renewable energy. Saul makes a pitch for Aotearoa to do the same, but much cheaper and much faster, instead of the government’s current plan to spend $1 billion importing gas over the next couple of years. He presents Rewiring Aotearoa’s paper on The Electrification Opportunity, which estimates cheaper power costs worth $10.7 billion per year by 2040.

Read moreDownloadFarmer's Weekly editor Bryan Gibson talks to Mike Casey on the InFocus podcast about paying back the capital on a recent solar investment in five years, the changes that need to be made to the 'braided river' that is our national grid to incentivise more farms to become power plants, and the strangeness of the current system that sees fossil fuels sent from Saudi Arabia, to Singapore and then onto boats and trucks, when we could be powering our electric farm machines directly from the farm.
As we've said before, it's not just us arguing for more rooftop solar. A number of academics are onboard and Kevin Trenberth, Distinguished Scholar at the National Center for Atmospheric Research in the US and honorary academic at the Faculty of Science, University of Auckland, is one of them. As he says: "Germany has about 20 percent less sunshine than New Zealand, but 3.7 million solar systems generating 61 gigawatts of power (12 percent of their total energy supply). In New Zealand, there is an estimated 200 MW from rooftop solar, and all solar (not just rooftop) provides under 1 percent of New Zealand’s power. A major reason for the very low uptake of solar in New Zealand is the absence of incentives and effectively, penalties against investing in it." We're doing our best to create incentives and remove penalties by pushing for symmetrical export tariffs, where a customer is paid the same amount for any electricity that is exported from the premises at peak times as they are charged for any power they consume at peak times. If we level the playing field, customers can become part of the energy system.

"Approximately two-thirds of New Zealand’s total energy needs are met by burning these expensive fossil fuels. But this country is one of the first in the world to cross an ‘electrification tipping point’, where the cost of buying and financing electric machines is cheaper over the long run than using fossil fuels. That leads to savings for individual households and it could lead to huge savings for the country as a whole.”

Read moreDownloadRewiring Aotearoa has been advocating strongly for rooftop solar, because it's the cheapest form of delivered electricity available to New Zealanders, unlocks a lot of the savings associated with household electrification and would help deal with dry years because there's more sun when it's not raining. So it's always nice when someone agrees with you and a piece by academics Stephen Poletti, Bruce Mountain and Geoff Bertram backs our argument up. As it says: "To alleviate the energy supply shortfalls primarily attributable to low rainfall, we suggest rapidly expanding cheap solar photovoltaics (PV), specifically rooftop solar for ordinary households. Our soon-to-be-published research suggests such capacity can be expanded quickly and cheaply... we encourage the energy minister to make the expansion of rooftop solar the top option for expanding the electricity supply and tackling the gentailer power that bedevils the market. He will almost certainly find it quicker, cheaper and more popular than importing gas.":

For example, 120,000 homes (or 5% of households in New Zealand) with a medium-sized battery could potentially reduce the peak electricity load by as much as our largest hydro power station, Manapouri. That’s why we’re asking the powers that be for something called symmetrical export tariffs so that customers with solar and batteries are paid fairly for their contribution, the payback time will be reduced and more people will have the confidence to invest in these technologies so the price of electricity can be reduced and we can keep the lights on in the event of an emergency.
Read moreDownloadOur hydro lakes are basically like big batteries and we need to save them for when they are most needed, says Mike Casey. Currently it's the job of coal to help keep this big battery charged during a dry year and that's expensive and polluting.

Read moreDownloadOne's also helluva cleaner, with the average solar install potentially stopping around one metric tonne of coal from being burned at Huntly, as Mike Casey outlines in his opinion piece about the current electricity situation on Newsroom NZ. Solar is by no means a silver bullet for our energy issues, but more of it on our homes, farms and businesses means we can potentially have our cake (keep electricity prices low for New Zealanders and reduce coal use) and eat it too (give customers with solar and batteries the ability to benefit if prices stay high). There will be benefits for everyone in New Zealand if more people own their power, rather than continuing to rent it. But we need to start thinking about customers as part of the infrastructure, something that the market has not been set up to handle.
Read moreDownloadThe Government has released a document outlining how it plans to meet our emissions targets. However, as stated by many climate scientists and media outlets, the combination of policies proposed in the ERP2 document will not keep New Zealand on track for Net Zero 2050, nor will they enable us to meet our third emissions budget. We want as many New Zealanders as possible to make a submission on the plan and share their main areas of concern and where they see the biggest missed opportunities. This guide will run you through the submisson process, outline our main arguments and even give you an email template to tailor.

As he writes: "No matter your political persuasion, one thing that seems to unite us is saving money so it has been encouraging to see genuine collaboration — reflecting, hopefully, a realisation that we are all in this climate crisis together and that electrifying the region means there is also something in it for the community."

This is an exciting conversation that really ignited the flame of opportunity and how farming can be a solution to the country's energy issues!"
“What I get a lot is people talk about electric vehicles and what they say with electric vehicles is that they’re great for people in the city, but they’re not great for the people in the country,” Casey told the 2024 National Renewables in Agriculture Conference in Queensland. “And I always have to remind them that that couldn’t actually be further from the truth. Literally, the more [kilometres] you drive, the better off you are driving an electric vehicle ... If charging purely from the grid it costs us around $9 for a full charge, however with our solar and battery array we are expecting the cost to be closer to $2 a charge and are currently collecting the data to verify this ... One of the most remarkable things we now see in New Zealand is the number of farmers that are adopting electric vehicles because they’re starting to realise that per kilometre cost [of fuelling them is] significantly less than [petrol or diesel]."

Rewiring Aotearoa's Electric Farms paper proved there are similar benefits for the rural sector if we can turn farms into power plants and, as he says - and as he has shown on his own cherry orchard - New Zealand’s farmers could reduce their operational costs by going electric and generating a lot of their own electricity through mid-scale solar and battery systems. And they can also make money by feeding electricity back into the grid at times of high demand. “Whether in the home or on the farm, electrification is a real win-win. It’s not just the right environmental decision anymore, it’s the right economic decision. It’s a no-brainer. We just have to figure out how to make it easy.”
Read moreDownloadQueenstown, Wānaka and the surrounding region have committed to one of the world’s most ambitious climate targets and pledged to create a carbon-zero visitor economy by 2030. It’s great to have a bold target to aim for but, as renowned electricity lover Thomas Edison said, vision without execution is just hallucination – and right now, the region is a long way off track and lagging behind a number of other places. So how can the region go from talking to walking? It basically all boils down to this: everything that can be electrified needs to be electrified - and quickly. Read Mike Casey's full opinion piece on Newsroom.
Read moreDownloadAnother great piece from RNZ's Eloise Gibson about our mixed rankings in the global EV charging stakes and the need to lift our game as EVs become more popular (globally, nearly one in five cars sold in 2023 was electric, a 35 percent year-on-year increase). The government promised 10,000 more public chargers by 2030 and $257 million in funding has been allocated to that goal. At this stage, it's not clear where that money will be spent, but one option that isn't explored in the story is the potential to make use of our 50,000 farms. Farmers investing in mid-scale solar and battery systems could not only power their own machines much more affordably and earn money for sending electricity back to the grid at peak times, but they could also become part of an extensive national charging network and create another new revenue stream. Farms are usually very close to the medium voltage networks, meaning they can scale up renewable systems without physical constraints or undue overloading risks to the distribution networks.

In New Zeland's Otago, cherry producer Mike Casey has been running a 6-hectare orchard without using any fossil fuels. Last year, it produced 80 tonnes of cherries for local and export markets. His fleet of 21 electric machines includes prototypes and traditional vehicles that have been converted to electric. "I never envisioned us going fully electric; I was just sort of thinking there will be some things that we can do to cut out diesel and cut our emissions," he said. "But what actually happened is we discovered we'd save about $40,000 a year of energy costs on our farm."
Read moreDownloadNew Zealand is going to need a lot more electricity as homes and businesses swap out fossil fuel machines for much more efficient electric versions. MBIE has just released a report showing a range of different scenarios and under favourable economic conditions the demand for electricity could rise by 81 percent by 2050. Where we get all that extra electricity from is an important strategic question for New Zealand and the report says wind and solar will be the "least cost" way to meet this demand. At Rewiring Aotearoa, we believe a lot of the extra electricity we need could come from rooftop solar and because it is produced where it is used it is the cheapest form of delivered electricity New Zealanders can get. Batteries are also dropping in price and rooftop solar and battery combinations can reduce peak loads while saving on energy bills. This is vital context for how we choose to build out the energy system to be low cost and highly resilient.

Following a keynote presentation at an agricultural conference in Perth, ABC's RN Drive show spoke to Mike about his all-electric orchard.
Read moreDownloadThe Guardian Australia's Aston Brown looks at the promise of electric technology in the agricultural sector as well as some of the existing barriers to update and talks to Mike Casey about the opportunities that already exist in horticulture and viticulture. He also talks to Terry Krieg, the co-founder of Linttas Electric Company, who is developing a semi-autonomous combine harvester that claims to reduce fuel use by a third. But it's not just about reducing carbon emissions and costs, says Prof. Ray Willis, managing director of Future Smart Strategies. “It’s about redesigning the vehicle for the first time in 100 years. If you make it electric, inevitably it turns out to be better, more durable, more reliable.”
Read moreDownloadRewiring Aotearoa CEO Mike Casey was invited to be the keynote speaker at AgZero 2030 conference in Perth recently, where he spoke about the opportunity in front of Australian farmers to do as he has done and electrify the machines on their farms and produce as much of the energy required to run them via rooftop solar - with battery storage offering another potential revenue stream. Not only does this save farmers money, it drastically reduces emissions through diesel use and, as the Countryman reported Casey as saying, "when everyone is winning, you don't need to fight".
Read moreDownloadThe Otago Daily Times and The South Today covered the inaugural Electrify Queenstown conference at Millbrook Resort yesterday. Destination Queenstown chief executive Mat Woods said the event was to show "the benefits of electrification, and what businesses can electrify such as vehicles, heating and cooking methods" and there was a huge amount of interest from the business community. "It was important to build an understanding that when things need to be replaced, replacing them with electric alternatives are not only better for the planet, but can also be cheaper, and more reliable ... Realistically we expected 50 people to turn up, but we had to cap attendance for the morning’s panel at 150 people." Rewiring Aotearoa's Mike Casey was the keynote speaker, and his electric tractor even provided heating for the tradeshow in the marquee.
Rewiring Aotearoa was proud to be part of the inaugural Electrifying Queenstown event at Millbrook alongside more than 150 members of the local business community. DQ boss Mat Woods told Mountain Scene the idea for the event was sparked by the Electric Homes report about New Zealand becoming one of the first countries in the world to reach the ‘‘tipping point’’ and there's a positive peer pressure in the Southern Lakes air as the region attempts to create a carbon zero visitor economy by 2030. To reach that goal it will have to, as Mike Casey said at the event, electrify everything that can be electrified - and quickly. As Kinloch Wilderness Lodge's Toni Glover said, the best way to do that is 'just start'. Kudos to Destination Queenstown, the Queenstown Business Chamber and Aurora for making it happen. We'd love to see more events like this right across the country so we can share the economic and environmental opportunities of electrification to more Kiwi businesses. Where next?

But the latest issue of its magazine is focused on the money (and emissions) Kiwis can save if they change their energy source from fossil fuels to electricity - and how there are even more savings on the table if you invest in solar panels. Consumer used a lot of the data created in Rewiring Aotearoa and EECA's Electric Homes report, and there are some handy tips in there for anyone thinking about upgrading their gas appliances or petrol vehicles.
Read moreDownloadRewiring Aotearoa's Mike Casey has plenty of fans, but the electric ones on his orchard are definitely the biggest. EECA's Technology Demonstration Fund helped Forest Lodge import and install two electric frost fighting fans in 2020 and, as the case study says, "the company has saved thousands on energy bills and significantly reduced its carbon emissions. These successes have been achieved without sacrificing frost-fighting performance". You might not need your own frost fighting fans, but electric equivalents - from hot water heat pumps to electric vehicles - are now cheaper to run and better for the environment.
Read moreDownloadJamie Mackay, who was recently made an Officer of the New Zealand Order of Merit for services to broadcasting and the rural community, says he has "a special thing going" with Rewiring Aotearoa CEO Mike Casey and admires the way he's driving innovation in the rural sector. Direct from Fieldays, he speaks with Casey about the practicalities of electric machines on different farms, and the new hybrid (and, soon enough, electric) utes.
From Fieldays, Rural Exchange speaks with Mike Casey about his presentation to kiwifruit growers at the Zespri tent ("it's all about how we save $40,000 a year on energy costs"), and how his orchard is showing other farmers what's possible.
