Factories shut after tripling of wholesale prices since July 1; Gentailers make $512.4m in profits since July 1, having paid out $4 in dividends for every $1 invested in generation since 2013
Ruapehu district has been battling for years to keep its snow and outdoors tourism industry going; now electricity prices are forcing timber mill and pulp paper plant closures that will cut 230 jobs out of the community. What is our government even doing?
Accepting the dividends and focusing on getting debt down to ensure home owners get an extra basis point or two of rate reduction, and to preserve high land values.
...much of this *waves hands in all directions* economic, social and political carnage is the result of a rookie political leader prepared to strike bizarre coalition deals to take power.
I've said all along that he is so far out of his depth. Hubris has got him this far - the real power brokers are happy to have him there but will throw him overboard as soon as convenient. I'd almost feel sorry for him as he is such a chump, but he's unworthy.
The light at the end of the tunnel is the Winston train about to derail the government when he is no longer DPM.
The Greens and Labour really have to get their shit together and avoid distractions like "should Tana be an MP". Focus on working to throw this hydra headed coalition out and fixing the myriad of problems that are becoming untenable, because I think we will have an election next year.
I think the factory should be putting solar panels up immediately with an subsidy from the Govt and whoever the electricity company who supplies them should give them a huge discount in order to keep those jobs. Honestly surely there is a way round this. Also apparently the snow is great at the moment. Lots of snow bunnies enjoying the slopes. Let's hope it gives the town a bit of joy and fills the koffers of locals.
Aotea Great Barrier Island is off the grid completely and has a large array of panels powering a group of shops, the gas station and a variety of businesses while saving power. It can be done and businesses should be getting interest free loans to go off grid.
Thing is- these kind of industrial users do use vast amounts of electricity- far more than a roof-full of panels could provide. Their power bill probably exceeds their wages bill even in normal times tbh (just me guessing). More hydro / storage + field-scale solar +wind, is probably the only way to get the power levels required. The great thing about electricity networks is they naturally work in both directions (distribution to users and aggregation to storage facilities from small-scale producers) but such operations are not commercially compatible with the current business model.
Kia ora Bernard, really interesting and important work! Have you tried to get in touch with Scott Willis from the green party? He's currently got a bill in thr biscuit tin aimed at fixing some of the market issues. Could be an interesting chat
Glad you called out the 'red herring' re: oil and gas exploration decisions - both the Labour and National-led governments have been deliberately misleading about this, which has then been picked up and promulgated by others. Let's be clear - there was never a 'ban' on this exploration, so there was actually nothing to be reversed. The 'ban' applied to the seeking of new permits only - there were/are plenty of existing permits - as you noted, the issue is that these existing permits have not found (at least not as much) as was expected. Further, if seeking new permits hadn't been banned, these permits would have been in areas that had largely already been declared as uneconomic to explore (by the oil & gas exploring companies themselves). It's been a classic case of deflective politics from both major parties with most of the unaware victims being their own voters.
Your reference Bernard to the extra level of tax coming from the very high prices of electricity and the big payouts to shareholders is true.
It is another layer of taxation indeed a secondary tax paid by domestic consumers. And it is paid from nett income after normal taxes been paid. And all this time there have been consents for many solar and wind farms. Bring back the Electricity Department now !
Oops pushed wrong button! It fascinates me that the small end consumer of electrons is asked to take cold showers( we have 18 panels on our roof) while the shareholders still get huge returns. Is it not possible that the shareholders could “take a haircut” like the rest of us to keep NZ workers in jobs? Or am I just a naive socialist and do not understand shareholder primacy? Or in fact neoliberal”Dog eat Dog capitalism”. I await our patient Alopecia suffering PM and the three headed Taniwha to explain it all to me. Does the system need changing?
Tautoko! Luxon is utterly deplorable, no doubt. But critiquing his lack of hair is no different to many of the lazy insults hurled at Ardern. There is so much to criticise Luxon for both as a PM and a numbered corporate employee!
Like a pay to save situation? surely that can be sorted with smart meters now? if you say sure I will reduce my power usage, if you pay me to, just like the smelter?
I'm with Octopus for electricity and they have been running regular trials where customers are refunded $2/kWh for every unit they don't use compared to regular usage. Most recent was 7.30-9am yesterday. I had an evening shower, delayed the washing machine and dishwasher and turned off the heat pump. On a previous session I was refunded $10. Not everyone can shunt their usage around, I wasn't willing to send my teenage son to school without a shower for example, but if we all did what we could and we're rewarded for it,that might make some difference. Of course, I'm still grumpy about the shitty policy settings that got us here. Maybe this ready-fire-aim govt can turn their attention to pushing a useful change through in the next week or so? Would make a change from bashing the health system or beneficiaries.
Given low lake levels and snow pack as we come into spring, I think we might be in a pickle next winter, going into the cold season with little water. It would be a good time to buy a diesel generator if you are running industrial freezers and so on for perishable goods.
I’m pretty sure it was this video that has (as well as good further info on the failed drilling in the last 5 years) a scary chart on what is expected to happen next year with even lower lake levels. https://youtu.be/VFzm7XjaGpg?si=dD1_Mnmpt_WBHvL-
I've just got off the phone to a solar installer who is happy to work with me (rather than offer me what is most profitable for them). The system being spec'd will include a battery so essential loads such as a freezer can be keep going even during an outage.
Geoff Bertram's recent comments on this power rort:
Comment posted on Newsroom story “Gas and solar to help answer ‘power profiteering’ claims” 14 August 2024
The call to roll out rooftop solar on a grand scale is absolutely right – but it’s important to remember why it hasn’t happened already. New Zealand was level-pegging with Australia on rolling out new renewables until 2013 , when part-privatisation killed new investment by the gentailers and anti- competitive market structures and pricing policies blocked private citizens from exercising their own initiative. (Besides which the installation cost of solar here is nearly double Australia’s because of the lack of scale and scope economies to date).
There are three key changes needed right now to unlock rooftop solar and battery backup:
1. Repeal the lines-energy split that was central to the Bradford reforms. That would mean that the local distribution companies (or new entrants!) could get back to their long-ago role of integrated operation of local energy systems and markets – both investing in, and coordinating, decentralised renewable generation and battery backup at community level.
2. End Transpower’s monopoly pricing arrangement under which all grid charges are compulsorily passed through to lines companies to pass through to all connected customers as (steadily rising) fixed charges. Those fixed charges really hurt the economics of rooftop solar (because even if you no longer require grid-supplied power you still carry the full grid costs unless you disconnect completely). Ideally, go back to the old Bulk Supply Tariff pricing arrangement under which the big gentailers would have to pay Transpower to carry their power to Grid Exit Points, where bundled wholesale supply would have to compete head-to-head with local distributed renewable generation. It’s called “competition for the market” and it has been completely stifled by the Bradford arrangements. Oil companies don’t (because they can’t) impose a fixed charge to drive into a petrol station. Supermarkets don’t (because they can’t) charge entry fees. They have to recover their fixed costs through variable charges.
3. Break up the gentailers to eliminate the self-hedging, barriers to entry and market-sharing that has kept independent retail confined to a tiny fringe. (And yes, the distribution companies, if freed from the lines/energy-split shackles, could be part of a retail revival).
As for Contact’s self-serving rhetoric about big balance sheets to fund investment, check out the last two decades. These fat cats didn’t get fat just yesterday – they got fat and stay fat by squatting on undeveloped investment opportunities that they control directly, while blocking entry by distributed generation. As for the Electricity Authority, the important thing to remember there is that as soon as it was set up in 2013 it demanded a memorandum of understanding relieving it of responsibility for regulating prices.
Rooftop solar is useless for this dry year problem, the scale of energy needed is almost beyond comprehension. Read the executive summary of the NZ Battery Project Indicative Business Case, prepared by Ernst & Young for Megan Woods & co. Here is the link:
One of starting assumptions behind that report is that the current market and regulatory settings remain unchanged. A big assumption.
"Overbuilding is considered a feasible way to achieve 100% renewable generation as it makes use of mature and well understood technologies (wind and solar) that can be built at scale under existing market and regulatory settings."
And the rest of the paragraph? Fixing profiteering is a great idea but it doesn't solve the dry year problem any more than rooftop solar will, these are supporting measures, not solutions, to the problem of missing Terawatt hours.
The executive summary clearly acknowledges that "it [the NZ battery project] aims to address an element that neither the market, nor policy or regulatory measures, are likely to solve on their own – the large-scale, long- term, and highly uncertain dry year problem."
Will better regulation save a bit of water? Sure.
Will it save enough to deal with NZ's unique dry year problem? Not even close.
How do we deal with the dry year problem at present? We light the fires of thermal, whenever we like. At least we did, until we started running out of gas - now we're having to de-industrialize too.
How do we deal with the dry year problem when thermal has been replaced with intermittent renewables? Terawatt hours worth of batteries! Overbuilding in the extreme!
We could explore the storage options tabled for further investigation by the project (link in my other post, nothing easy about those either), or we could drastically simplify our lives to live with an energy reduction (most sustainable, but impossible by choice). The most likely scenario I believe is we gradually build intermittent renewables backed up with imports of more gas/coal to keep the place civilised, and wait until the technology for NZ's unique energy security/storage/risk use case emerges at a viable price point and scale before we cut the fossils.
We had a solution for the dry year problem, but due to Willis insisting on tax cuts - and no doubt lobbying by the gentailers - it was one of the first items the hydra head threw on their bonfire.
Is rooftop solar useless, or are people missing the fact that using the solar at other times means less hydro needs to be used and therefore becomes the storage for the dry year, or those few months...
Solar will help conserve water for sure, but the issue is our lakes are too small, they don't actually store much water. So if it's not raining we still end up with a problem. This is why things like Lake Onslow got explored; from a conceptual/theoretical point of view, solar backed up by pumped hydro is absolutely marvellous
Here is a link to the documents produced for the NZ Battery Project "to explore possible renewable energy storage solutions for when our hydro lakes run low for long periods":
I note that in the non-hydro options analysis report by WSP, 1TWh of storage was the minimum storage criteria to cover the dry year problem. The options it recommended for further study are bioenergy (grow & store wood to burn), controlled geothermal, and hydrogen stored as liquid ammonia. Batteries were not recommended for further study due to cost, nor was compressed air storage. Here is the link to that specific document:
To put the scale of the storage problem in perspective, at around $1000 per kWh for batteries (e.g. Ruakaka Battery Park, 2024) you're looking at $1 trillion for 1TWh of storage.
Pursuing exponential growth and breaking fewer carbon-to-carbon molecular bonds are not compatible ideas at present, unfortunately...
Thank you Bernard. What a mess. The big picture and multi-pronged solutions are the only way out, which justifies your project of course. Decades of catering excessively to share prices, selling off assets, NZ laden with O/S owned companies using eye-watering amounts of energy with sweet deals eg Tiwai smelter (Rio Tinto and Sumitomo owned), Winstones(now Malaysian)and some very govt supported, et al They provide some NZ jobs but at extreme cost. This needs the large pic, with new and imaginative job creation, better laws and other regs round donations and lobbying, conflicts of interest in decision makers et al being a large part of it. So many things would be addressed if these regs were implemented, incl proposed gun laws, tobacco/vape issues, fast tracking of mining approvals without proper EIS et al. The current mob would not be there - another less damaging version of National might be but not this small minded lot. I do like some of their talk re a really competitive NZ bank but I am sceptical as it makes them look NZ-focussed while chances of it happening are negligible. The 4 main banks, the cartel, are US-owned and Australia managed I believe so much skin in the game. Some tightening of regs mentioned could happen quickly if the will were there and it won't be right now. Labour needs to transform itself and turn this around. It might get traction.. or a break away Nat party might do it.
• Get distributed renewables online as fast as possible to drive fossil fuels right out of the electricity generation mix
• Impose low-price contracts on established hydro generators (effectively tax away their rents)
• More fundamental: get ready to renationalise hydro into a single integrated operation and use it to counterbalance intermittent renewables – especially if in the meantime you have got local energy pools/networks going
• Even more fundamental: plan to re-integrate large hydro and geothermal generation with the Transpower grid to hold final price down while covering all costs
Re the comment by Contact CEO Mike Fugue "We're encouraging the politicians to keep their hands in their pockets. Don't fiddle with the market". Hah - a rather self serving comment. So he thinks its more important that the market stays the same than NZ businesses remain open? The market needs fundamental restructuring rather then fiddling! E.g. So that generation payments reflect the long run marginal cost not the short run marginal cost. To base payments for generation on the higher short-run marginal cost of fossil fuels such as coal when alternatives such as large scale batteries, wind and solar are cheaper than new large fossil fuel alternatives and when the cost structures between hydro and fossil fuel generation are fundamentally different does not send the appropriate incentive to invest in new, cheaper alternative generation. That the govt is talking about investing in LNG and more gas fired plants is not economically rational when there are these cheaper and more timely alternatives. And perhaps there should be incentives and sanctions for generators who hold resource consents for wind farms etc but don't actually build them. I understand that the full assessment of the Onslow pumped hydro storage option was not completed - it might have been a sound long term investment, not least if one assumes rising carbon prices.
A recommended principle for a restructured electricity market is that it results in the investment in the least-cost (including carbon cost) sources of supply based. (And that includes comprehensive investments in household energy efficiency, HH solar and HH batteries). This could be implemented through the Electricity Authority calling for bids for additional supply and using a national cost-benefit analysis approach that includes carbon costs to approving least cost new investments. Such systems apply in the US and Canada. E.g. in British Columbia the electricity companies and market regulator have mechanisms to encourage in investments in the least -cost alternatives, including investments in energy efficiency. E.g. British Columbia Hydro - a Canadian Crown corporation has incentives for hh solar and energy efficiency. https://www.bchydro.com/index.html

Hi Dan
Are the ski fields keeping their snow guns working?
Job losses in some town far, far away doesn't impact 'my' life, but not being able to go skiing - oh, the inhumanity (s).
Hey Steve, town has been packed with snow folk for the last few weeks, business people smiling and cash flowing into the local economy..then this.
I think the factory should be putting solar panels up immediately with an subsidy from the Govt and whoever the electricity company who supplies them should give them a huge discount in order to keep those jobs. Honestly surely there is a way round this. Also apparently the snow is great at the moment. Lots of snow bunnies enjoying the slopes.

Great for GB, but who funded it?
the people who live there, mostly.
And it's kinda expensive to just exist there.
Thing is- these kind of industrial users do use vast amounts of electricity- far more than a roof-full of panels could provide. Their power bill probably exceeds their wages bill even in normal times tbh (just me guessing).

So he thinks its more important that the market stays the same than NZ businesses remain open? The market needs fundamental restructuring rather then fiddling! E.g. So that generation payments reflect the long run marginal cost not the short run marginal cost. To base payments for generation on the higher short-run marginal cost of fossil fuels such as coal when alternatives such as large scale batteries, wind and solar are cheaper than new large fossil fuel alternatives and when the cost structures between hydro and fossil fuel generation are fundamentally different does not send the appropriate incentive to invest in new, cheaper alternative generation. That the govt is talking about investing in LNG and more gas fired plants is not economically rational when there are these cheaper and more timely alternatives. And perhaps there should be incentives and sanctions for generators who hold resource consents for wind farms etc but don't actually build them. I understand that the full assessment of the Onslow pumped hydro storage option was not completed - it might have been a sound long term investment, not least if one assumes rising carbon prices.
A recommended principle for a restructured electricity market is that it results in the investment in the least-cost (including carbon cost) sources of supply based. (And that includes comprehensive investments in household energy efficiency, HH solar and HH batteries). This could be implemented through the Electricity Authority calling for bids for additional supply and using a national cost-benefit analysis approach that includes carbon costs to approving least cost new investments. Such systems apply in the US and Canada. E.g. in British Columbia the electricity companies and market regulator have mechanisms to encourage in investments in the least -cost alternatives, including investments in energy efficiency. E.g. British Columbia Hydro - a Canadian Crown corporation has incentives for hh solar and energy efficiency. https://www.bchydro.com/index.html

Geoff Bertram of Victoria University has produced a number of papers etc on out electricity market and its flaws and his work is worth reading. https://geoffbertram.com/publications/#the-new-zealand-electricity-industry His work indicates that the problems with the market were forseen but ignored.
I don't want 'open banking', though I don't mind if others do.
I want a full-functional personal CBDC* account at the RBNZ, and fully bond-backed savings accounts there for my term deposits & Kiwisaver.
Oh, and while we're at-it, I want the banks out of the residential property market, and the re-establishment of old-fashioned Mutual / Building Societies for that purpose.
