News & Updates

Lowest prices are just the beginning this week as Bunnings gets into the solar and battery game in a big way in Australia with plans for a zero-dollar upfront deal; Port Nelson has electric lift off with its new crane and a new solar powered hybrid cargo ship is launched; Inductive Robotics wants to bring chargers to the cars, rather than the other way around; a new campaign suggests that South Australians are revolting and loving it; and Johnny Solar releases a beautiful version of The Kinks' Lola.

Flexibility is an important aspect of our future energy system because we need to avoid over-spending on infrastructure and increasing bills when we could instead make better use of our existing poles and wires. The Electricity Authority's moves to lower off-peak power and offer higher export rates at peak are positive, but, as Kimberley O'Sullivan writes, "it is clear the sheer size and complexity of the problems mean government action, with community and industry collaboration, needs to go beyond slightly cheaper electricity when there is less demand." As she says, helping more New Zealanders, particularly renters and low-income homes, access solar with long-term low-interest finance is one of the main ways of reducing the cost of electricity.

Gavin Shoebridge runs through the many reasons EVs make sense in an opinion piece in The Post and points to Rewiring Aotearoa's research showing that "with smarter planning, EVs can play an important role in New Zealand’s energy grid, with the potential to save billions as a country. By tapping into EV batteries as decentralised energy storage, we can flatten peak demand, reduce blackout risks, and save on long-term infrastructure costs".

Rewiring Aotearoa has long argued that there were arbitrary restrictions on the amount of power those with rooftop solar could export to the grid and that was leading to smaller systems and savings - and higher electricity prices for everyone else. We said we'd be keeping an eye on the networks to ensure they followed the Government's recommendations so it's pleasing to see Aurora double its export limit for households from 5kw to 10kw.

There are an increasing number of Bright Sparks in the rural sector who have figured out that there is money to be saved and emissions to be reduced by embracing solar. Aidan Bichan from Kaiwaiwai Dairies in South Wairarapa realised that earlier than most.

Auckland CBD's biggest solar install shows that existing rooftops - big and small - are an easy win for electricity generation; New Zealand researchers leading the world on solar efficiency; a clever scheme to train up more heat pump installers in the UK; a very early example of loadshifting; and electric school buses hit the road in the US.

Fairly compensating households, farmers, and businesses with solar and batteries that export power at peak will give customers a better deal and give a much needed jolt to a market that has been slow to innovate and make the most of new technology.
Gas, batteries and emissions are discussed on RNZ's First Up - and we have some thoughts.
For Jack Tame, the question of going solar is not if, but when. As he said on his Newstalk ZB show after confronting a big electricity bill, "there are only so many gains to be won from policing light switches and shower times. I’m seriously wondering about solar ... The huge surge in solar is being driven by economics. Put simply, solar power is way, way, way cheaper than other forms of electricity generation. Between batteries and solar panels, the technology is only getting better and only getting cheaper."

Solar smashes a few records and helps the world get off gas and coal; homes, not power plants, are the key to lower power prices; 24 new bus chargers are installed in one day in Auckland; DARPA makes some very special popcorn by beaming energy wirelessly for 8km; and an astronomer discovers an addictive new star gazing app.
We know that going electric can help reduce household bills, but the upfront costs are still a big barrier for many. Getting past that requires access to finance and that's now closer than ever.

Rewiring Aotearoa's submission highlights that successful digitalisation should allow customers to maximise benefits from their provision of demand flexibility and solar and battery exports, without third parties (aggregators or VPPs) routinely taking a cut of the value. Retail offerings that include time of use prices and fair export tariffs will be key enablers of successful digitalisation of the electricity system. Customers need a fair deal through their electricity prices and export tariffs. This means the customers need to have the option to choose from a range of retail tariffs that include time of use prices, fair export tariffs (that reflect the value in the wholesale market) and symmetrical export tariffs from distributors.
'The neighbourhood effect' is a powerful force when it comes to influencing purchasing decisions. And that's why Bright Sparks like Stephen Drew are so crucial because they can give community members the knowledge and confidence they need to explore these cheaper, cleaner electric options for themselves.

Redwood Materials claims a record with old EV batteries used to store cheap solar to run a small data centre; OneEnergy launches a product that puts the sun directly into your water tank; more plug-in solar news from Ikea and Utah; very fast electric boats and cars; and a beautiful union between two star-crossed lovers.

While we like to talk about the economic, environmental and resilience benefits of using more electricity, there’s no denying that the news is dominated by stories about increasing electricity prices.

Evnex has established itself in New Zealand, and it's starting to plug in to the Australian market. Founder and CEO Ed Harvey and commercial & technical account manager Tony Davis take us for a tour of the Christchurch office where they assemble and test their smart chargers.

Rewiring Aotearoa's Queenstown Electrification Accelerator is on a mission to create the lowest bills, lowest emissions and highest resilience for the region, and make it easy for homes and businesses to go electric. And it just got a big boost after receiving $220,000 from the Central Lakes Trust.

On The Detail podcast, Sharon Brettkelly talks to Consumer's Paul Fuge about dwindling gas reserves, rising prices and why relying on new gas discoveries is a mug's game.

Victoria looks to get off the residential gas with a range of changes, an announcement in the UK gets everyone excited about V2X, why EVs are a good hedge against geopolitical strife, new comparison and switching partner announced (and we have a couple of requests), and it turns out that keeping the emissions out of the sky is a better idea than trying to catch them.

Rural Roundup's Andy Thompson talks to Mike Casey, a keynote speaker at the Primary Industries Summit, about the country's energy system and the growing appetite for solar among farmers.
More strong signals from the Government that it's focusing on lowering bills and embracing solar as projects in Rakiura / Stewart Island, Bay of Plenty and Hawke's Bay get loans of up to $28.1 million combined. "Solar power is playing an increasingly important role in increasing electricity generation in New Zealand. It will help us reach our renewable energy targets and bolster the security and affordability of our energy supply,” says Energy Minister Simon Watts.

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 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.
