As long as they cut the power off to anyone who voted Green or Labour first, or runs an electric car, I'm ok with letting the coal run out.
Probably should have a permit to buy fuel based on your voting preferences too.

Transpower only run the national grid That is their job but they are clearly also the government's vehicle to push the unreliables nonsense per www.transpower.co.nz/about-us/our-strategyquote Our electricity system is already around 85% renewable and this is set to increase over the coming years. We need to make changes today to maintain our safe, secure and reliable supply of renewable energy as demand grows, encourage investment, and to build the workforce needed to run the new energy system.
We’re not doing this alone. Improving New Zealand’s energy sector is a collaborative exercise. We are working closely with policy makers, regulators, generators, electricity distribution businesses and consumers of all sizes including industry.
Working together is the most efficient way we can electrify our economy. |

Very happy with this sunny weather . Got the toaster and the espresso machine going full noise and have 800W coming in off the solar array already . Solar hot water hit 75.C yesterday .
Our american made charge controller has a setting for switching to grid tie once the batteries are charged which is usually 10.30-11 on a day like today . We could then sell power for 5 hours if we were connected to the grid …if such a thing is allowed ? Im aware there’s many gridtie systems but they don’t have batteries or they have a small back up power wall type thing .
Full blown solar systems with grid tie are popular in the US because the grid is so unreliable . If we relied on the grid right now I would be thinking of alternatives . Battery storage is not difficult anymore 9KW of storage in lifepo4 takes up as much room as a medium size filing cabinet .

I believe the financial issue for you to go on grid tie is you will be subject to full line charges which would most likely cancel out any benefit you get from "selling" power into the network. Better to stay off-grid in your situation |

Better to stay off-grid in your situation Yeah na last qoute to get power here 15 years ago was 100k so it’s definitely off the table . My point was quite few people in suburbia would be in the position to be grid tied but with a full battery bank . But I’m not sure the powerco’s allow that arrangement ? So you mostly supply power to the grid with very little to no consumption from the grid . from what I can see the current arrangement of grid tie is similar to a term deposit with a bank . They pay you less for it than what they sell it to you for . And 99% of people have no batteries or just a token powerwall will run the house for a few hours . |

Power generators can produce power cheaper than you or I can, regardless of who we do it. The differentiator comes down to the cost of grid connection. In a lot of rural and as per your example, it is simply prohibitive. Therefore offgrid power is far more economic. Noting that offgrid power, being solar panels and storage has become substantially more economic in the last decade or so. I had a really solid look at putting solar on my residential house. It had a payback that wasn't too bad in years, for a straight solar installation (no storage), but as soon as I applied the cost of finance it went straight out the window. Starting looking at it when mortgage rates were around 3% and it was a possibility, but with mortgages rates around 7% it was just dreaming. And the buy back rates on solar are marginal as well. A mate has solar and really the buy back is not part of the economic equation. It is more something to do with the spare solar. He has high use though, heats are spa pool during the day and now charges a Labour subsidised new EV. Easy to get solar payback if you have high lectrical demand. Not so much if you have low demand, LED lights and a wood burner. |

In the 15 years or so since the last winter drought the middle class has exploded , the population has increased and house hold electric gear has gone crazy . But Power generation has not increased in line with that . Im picking the next dry winter will be far worse than the last one unless the upper middle class turn off the bach , the boat in the marina , the pools , the beer fridges and spillover fridges in the garage , limit heat pump use and of course park up the Tesla or whatever EV . The two new data centres sound like needy bastards too , I read some where they are in the range of 2-3MW each ? |

The two new data centres sound like needy bastards too , I read some where they are in the range of 2-3MW each ? Energy security is definitely an issue as was high lighted by the "panic" created by Transpower couple of days ago. Not something you subject to regular financial analysis from a home owners perspective, but certainly huge from a national productivity perspective Ref your comment about Data Centres, reading this article a couple of days ago about the US looming self imposed energy disaster www.cfact.org/2024/05/04/the-looming-electricity-shortage/there was this comment (my underlining) But the electricity needed for the new artificial intelligence (AI) revolution will be greater than that needed for EVs, electric appliances, and green hydrogen combined. Amazon, Alphabet, Meta, Microsoft, and dozens of other firms are building massive new multi-acre data centers. In addition to new facilities, servers in the nation’s 2,700 data centers are being upgraded with new high-performance processing cards, boosting data center power consumption by six to ten times. Today, data centers use about 4% of US electricity, but the AI revolution is expected to boost that demand to more than 20% of US electricity consumption within the next ten years. Cryptocurrency generation, such as Bitcoin, also uses large amounts of electricity.This projected 500% increase in demand to power data centres is just huge and you can be sure power planners have not even though about this, they still have not got their heads around the increased demand for EV's |

The two new data centres sound like needy bastards too , I read some where they are in the range of 2-3MW each ? I bought a generator. 1200w for $400 from Repco. Sufficient to keep my freezer frozen, fridge cold, and to run my water pump (but not all at the same time) and to recharge my myriad of rechargeable batteries that power my collection of camping lanterns. I've got the wood burner, and gas for cooking (BBQ and gas ring). So if I can keep my food secure (frozen), I've got light, heat and drinking water. About the only thing I don't have covered is a hot shower, but I'll put that down as a first world problem. So far I've only used the generator on the boat. Turns out it can run all the power tools we need, being sanders, a router and a full sized vacuum cleaner (for cleaning sanding dust) I got the generator pre-covid, still have preper hang-ups having been dropped into the Chch earthquake with zero preperation by the Air Force. So the main purpose of the generator is covering for a major natural disaster, i.e. extended power outage of several weeks, but it also covers us to keep the freezer frozen in the first instance of basic supply outage. |

They pay you less for it than what they sell it to you for . And 99% of people have no batteries or just a token powerwall will run the house for a few hours . The majority of systems are grid tied according to a professional mate who installs the things. But he reckons it's a rip off in NZ as the mobs who organised it i.e Harrisons, Solar City etc push the things as green and planet friendly but try to keep away from the costs as payback on a system like that is crap for the home owner. Also power companies pay shit and love grid tied as they make moonbeams off them, buy for 4 or 5c, sell for 25c, pure bank margin shit. Also most of those systems have tiny banks so if mains goes down they have something but not much for not that long.
I am told the Power Cos are legally allowed to charge you line rental of the lines run to your boundary even if you aren't connected. We're in the planning stage of a development in Bayswater and we intend to go full off grid solar in them all, so trying to clarify that powerco things, some say yes, some say no, it is as clear as mud. I have asked the powercos but the front line staff don't know so I've gone to management but nothing heard. If that is true you'll probably see me screaming at them as that is 101% total bullshit!!! Solar wizz mate reckons full off grid will work,from our rural experience I full agree. They are designed to be solar off grid and purchasers will be made well aware to use power thristy gear at 10am not in the evening.
Rural power bank is 9.6kW 500mm x 500mm x 500mm. 4 x 200Amp Gels.

Pleased to say I have the barrel smoker in full swing,producing enough smoke to upset the neighbour,who came over and told me to stop.Not happening got veges and 2kg of bolar cooking,tell you what mate.Next 1 of your chickens comes over I will smoke it for you. Had a vist about 10 minutes ago from the local fire boys,they had a call saying I had a rubbish fire going,they left without question  |
