Farmer'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.
A cornucopia of electrification optimism this week, with Ubco inking a big deal in Australia, FTN Motion also getting set to head across the Tasman, Octopus Energy's founder Greg Jackson on the new champ in energy town, David Wallace-Wells looks at what we will do with all our 'free' solar power, and Germany shows how loosening up permits for renewables has led to a huge and rapid boost of energy supply.

"Combined, New Zealand homes and businesses are currently spending around $55 million every day or $20 billion per year on fossil fuels, most of which are imported," says Saul Griffith. "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.”
Alka Prasad digs into the numbers in the Investing in Tomorrow report and finds out how New Zealand could save $29 million per week just by electrifying our homes and cars.

August 28: Rewiring Aotearoa has welcomed the announcement of a taskforce to address issues in the electricity market but says the time for investigating is over and it is now time for action.

"The principle narrative of the last few decades – that we can’t afford to solve climate change – is just not true," Rewiring Aotearoa CEO Mike Casey tells Ellen Rykers for the Future Proof newsletter as the organisation launches a new report outlining the economic opportunity of electrification called Investing in Tomorrow.

"You can actually now demonstrably show that for large sections of every economy in the world, it is now cost effective to solve climate change – and that's a pretty radical new idea," says Saul Griffith.
Following the launch of the Investing in Tomorrow report, Nine to Noon's Kathryn Ryan spoke to Dr Saul Griffith about the massive savings opportunity that electrification presents New Zealand households and the nation as a whole, the lessons we can learn from other markets and changes we need to make to our electricity system.

We’re all about the win-win-wins at Rewiring Aotearoa. And, as Dr Saul Griffith says in this presentation, electrification promises to save every New Zealander money, greatly improve the country’s books, and slash our emissions. What’s not to love?

New research from Rewiring Aotearoa shows electrification could save New Zealand households around $29 million per day by 2040 and massively reduce the country’s emissions.

More news, views and hullaballoos from the world of electrification, with a big event next week spelling out the economic opportunity for New Zealand; red states embracing solar and coppers embracing EVs in the US; Norway getting close to 100% on EVs; hydrogen cars sucking; Europe looking to the sky to get off Russian gas; and exciting news for e-bike entrepreneurs and explorers.
Rewiring 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.":
Our ERP2 submission outlines what we think needs to be done to improve the Government's plan to reach our climate targets, electrify the Aotearoa New Zealand economy and build a fairer future energy system for New Zealanders that saves people money and does not leave anyone behind.
Batteries in homes and businesses may seem individually small, but they could have a significant impact on the security and resilience of New Zealand’s power system. 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.

Our 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. But when it doesn't rain it shines and between April-August, sunshine hours are, on average, 5% higher in a dry year compared to the average.
We're all charged up this week with some more big - and magical - machines; one of the best looking caravans we've ever seen (plus some EV towing info); how the big batteries in these big machines are starting to play a role in the energy system; a solar breakthrough that might allow us to put solar cells on our clothes, mobiles or cars; and if you liked the movie Don’t Look Up, you might be into a new play at Silo Theatre called Scenes From The Climate Era.

There is a relevant saying: ‘Information wants to be free’. While the proposed Consumer and Data Product Bill takes a step in that direction, it does not offer the level of freedom that could be technically accomplished, nor the level of freedom that is likely to unlock the maximum level of innovation.
One'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.
"Electricity prices are higher than ever - clean energy charity Rewiring Aotearoa boss Mike Casey wants to change the game with solar power."
The 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.

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.

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 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.
