News & Updates

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.
Read moreMike 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.

Read moreThe New Zealand Herald's Chris Keall (paywalled) has gone deep on the SolarZero collapse and, while there are still questions being asked about the public investment, Rewiring Aotearoa CEO Mike Casey says it was a business model failure and, just as Kodak didn't define the camera industry, this shouldn't define a sector or dent confidence in the technology. Energy Minister Simeon Brown also talked about a number of positive changes that will make it cheaper and easier to install rooftop solar.

Read moreOverall, 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.
Read moreShareable linkDownloadIn this future, consumer infrastructure needs to compete on a level playing field with traditional infrastructure – if a $10,000 battery on a consumer’s premises can provide the same service as a $20,000 supply-side asset (a network or generation investment), the consumer’s asset should be selected for the service. 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.
