"The answer isn’t just to fast-track and crack through and remove the barriers. It’s actually to do some strategic thinking about what can go where. Is there enough lower value land to accommodate all of this stuff? And if there is, let’s develop a permissive regime for that and protect the best bits."#GaryTaylor, Environment Defence Society, 2023https://northandsouth.co.nz/2023/07/24/renewable-energy-by-2050/(1/?)#RMA #RenewableEnergy #development #EDS

That will provide not only a good environmental outcome, it will provide a good climate outcome and it’ll give the sector a bit more certainty about where they can go."We can’t lose our heads in the rush to renewables. We’ve got to be working towards good environmental and climate change outcomes, and not sacrifice one on the pillar of the other.”#GaryTaylor, Environment Defence Society, 2023https://northandsouth.co.nz/2023/07/24/renewable-energy-by-2050/(2/2)

"In March, Transpower reported there were 30GW of new renewable generation 'in the pipeline' — about half of which were solar farms. While most of the projects were in an early stage, the state-owned enterprise believed the country was already on track to more than double our generation."#GeorgeDriver, 2023https://northandsouth.co.nz/2023/07/24/renewable-energy-by-2050/BTW why on earth is #Transpower structured as a corporation? It's 100% publicly-owned and always has been, and the national grid it stewards is a natural monopoly.

Also, if you click on the #TransPower tag, you'll see that in 2025, giving an electricity company this kind of newspeak name creates potential for confusion with something totally unrelated ; )

"Greenpeace is also advocating for household solar projects to be given priority over large scale commercial projects. 'Just because energy production is renewable, it’s not necessarily sustainable', Greenpeace lead climate campaigner Christine Rose says. 'The adverse environmental and social impacts of the centralised ‘Think Big’ generation model can be addressed by rooftop solar and battery storage'.”#GeorgeDriver, 2023https://northandsouth.co.nz/2023/07/24/renewable-energy-by-2050/#RooftopSolar #DomesticBatteries #ThinkBig

"In 2019, a Transpower report found that if 58 per cent of households and 25 per cent of businesses in New Zealand had rooftop solar it could provide more than half of the power generation required. If 69 per cent of households and 40 per cent of businesses install solar, it found it would generate two-thirds of our current power consumption."#GeorgeDriver, 2023https://northandsouth.co.nz/2023/07/24/renewable-energy-by-2050/(1/2)

"Ralph Sims says in future, small-scale nuclear power may prove more economic, and may be more palatable to the public if mass scale wind and solar farms are the alternative."#GeorgeDriver, 2023https://northandsouth.co.nz/2023/07/24/renewable-energy-by-2050/Just no. Not now, not ever.

@strypey You can have a nuclear power plant once you have a proper plan to look after the waste for 10,000 years. No? Ok, no plant allowed.

I mean FFS, we're a small, tectonically active country, already running out of safe dump sites for the wastes we currently produce. Where does Sims think we'll build facilities to keep radioactive waste, and how does he think we'll keep safely contained through tens of thousands of years of earthquakes and volcanic eruptions?The hubris is mindboggling.(2/2)

@podsrover I'm always curious about the nuts and bolts of doing this kind of system. What did it cost roughly to get your solar installed? Are they grid connected or on a separate local circuit? What kind of storage did you get, and what capacity?If you don't mind sharing of course.

@strypey its not all finished yet but it will be connected to the grid, we got a 14kwh battery and it cost around 25k

@strypey its a victron battery, lfp chemistry. I haven't actually seen it yet. Due to be installed next week with a bit of luck.

If you're not already locked in, I highly recommend checking out Sodium Ion batteries.Friends of mine got some about a year ago, ordered directly from a supplier in China, and can't stop singing their praises. They reckon they're cheaper per unit of capacity, last longer even with full cycling, and of course they come with zero fire risk : ) Also they're free of conflict minerals, easier to recondition/ recycle, and fairly nontoxic at EOL.(1/2)#renewables #SodiumIon #batteries@podsrover

The world's biggest battery maker is getting into the tech too, leading to sodium ion batteries that have;"... higher energy density than even those of most current Lithium Iron Phosphate (LFP) batteries, coming in at 175 Wh/kg.That’s above the roughly 150 Wh/kg seen in many mass produced LFP batteries."https://thedriven.io/2025/04/23/worlds-biggest-battery-maker-flags-first-commercial-sodium-battery-packs-by-end-of-year/(2/2)

@strypey @podsroverFor new deployments Sodium look like the type to go for. Unfortunately they do not play well with LiFePO4 because the charge /discharge curve is completely different meaning that you can't mix them with other battery packs. I have several LiFePO4 strings in both my systemsSodium cells currently don't have the cycle life of LiFePO4 but rhey are improving.

@llnz > the UK equivalent (creatively named National Grid) is a private company, so it could be worseOh believe me the Ruthenasiacs would have hocked ours off too if they thought they could get away with it. As with the roads and water infrastructure, and the surviving bits of the public education and health systems, there were dedicated and militant anti-corporatisation campaigns to stop them.

@midgephoto > Gridscale projects can conveniently provide power at grid or intermediate voltagesLike the quote I was commenting on, that sounds like corporate propaganda produced by "gridscale" developers to me. Generating closer to the point of use reduces transmission losses, and 1000 solar panels is a 1000 solar panels, whether it's spread across hectares of productive farmland, or hectares of unproductive rooftops;https://www.rewiring.nz/news/more-rooftop-solar-in-cities-would-help-solve-nzs-energy-crisis---and-build-disaster-resilience

@midgephoto > making process heat from power collected off a million rooftops... probably isn't a good use for electricity from solar. Facilities that need process heat would be better to create their own renewable generation, on our near the site where it's used. Again, consider transmission losses.> perhaps the network would have been built differently if that was the ideaIt's well-established that the grid needs to be upgraded for the 21st century. So this is just one more reason.

@strypey yes that's probably the way we should have gone but a bit late now. LFP is pretty safe though and reasonably durable.

@podsrover > LFP is pretty safe though and reasonably durableThey'll get your started, and I suspect that by the time you need to replace them, sodium ion will have taken over the market. Hopefully with much if it being manufactured domestically.
