Aerospace Engineer here: This sounds more like a political and management issue rather than a technical issue. The idea of a community battery, especially in country towns makes an awful lot of sense. Buying a bigger industrial size battery in a 10ft or 20ft container SHOULD be a lot cheaper than smaller individual power walls. I was just touting today with someone talking about the costs of nuclear and they were whining about the costs of safety and labour. Safety and labour cost NOTHING compared to bad project management. *What's more if there are Cost Plus (C+) contracts involved then bad management can be MORE profitable than good management.* People often misunderstand that if a C+ project is mismanaged and takes longer the contractors make more money. For example. On a 1 million man hour project with each man costing $100/hr which in the remote mining industry is realistic. Those million hours cost $100 million. If the C+ rate is 20% then the contractor makes $20 million (cost + 20%). *BUT* if the contractor works a little slower and is allowed to get away with it. *OR* if the project managers allow too many design adjustments that take longer. *AND THEN* the contractor hours go up 10% to 1.1million hours the cost become $110 million and the profit becomes $22 million. *Its not bad working poorly or just letting project managers stuff up to get an extra $2 million.* That's what's killing projects across the Western World.

Thanks Rosie -As a rural New England town we have a municipal owned utility. More than a decade ago the town did approve two 1.5 MW wind turbines, which are still running today. We are planning a 2MW/8MW*hr battery and are working to support the development of a 1MW solar field. We don't sell shares of these assets to our ratepayers but we support the community environmental goals. We hope to eventually have smart meters and roll out a Virtual Power Plant (VPP ) style demand response system . We have a voluntary text message system to encourage peak load reductions, and support WiFi controlled EV chargers. Communities can be very innovative, but sometimes we can make mistakes too.

One thing often overlooked but pleased to see the Yack community address - invest in reducing load before trying to power it with renewables. Typically there is a lot of low hanging fruit so every $ spent improving energy efficiency will save multiples of renewable infrastructure $. And reduce energy and GHG emissions from manufacturing as less infrastructure is required

Agree Stephen, though depends a bit on circumstances. 90% of the time that is right. In my situation I found that adding one extra PV panel satisfies my daily water heating needs so more cost effective than solar HW. But that was after making sure hot water capacity is optimised (ie not oversized!). It helps that I live in warm sunny location and have low HW use. Point is, do some analysis of electrical consumption and reduce it as much as practical before adding renewable.

Thermal hotwater needs heavy infrastructure, a plumber, an electrician for the back up heating elements and a check on strength of the roof structure. Solar thermal hotwater was old school technology long before our PV panels.

Yep, agree thermal solar significantly more expensive - and all you get is HW, whereas increased PV more useful as can serve any electrical load. How much area is needed to heat water by either method really depends on local climate, solar irradiation and how much HW the household uses. We need only about 3m2 of PV but have lots of sun, warm incoming utility water and usually only 2 people. But very different in other scenarios I know! Loving Rosie’s great channel

Remember, all/every monopoly gets its exclusive business privileges from govt. and uses them to extort us.

Thanks for covering this. I think that community power is necessary as part of the "all of the above" strategy to fight climate change. There is not time to wait for large grid scale projects to solve the fundamental issue of reducing the rate we are putting carbon into the atmosphere. Every idea that creates less carbon than displaces has to be explored and implemented. We need Cheap basic transportation EVs and electric trucks and busses as soon as possible. For trucks and busses, electric hybrids could cut diesel use in half as a intermediate measure. Could you imagine reducing diesel carbon emissions by half globally while full electric heavy haul infrastructure is created? I still don't think hybrid cars are worthwhile but since truck emmissions represent such a large problem I would concede that electric semi trucks with a small diesel range extender could help bridge the gap since a generator can run intermittently at it's most efficient RPM when needed to recharge a medium sized battery.

Community batteries can be the best, most cost effective method of supporting the grid locally as well as soaking up excess solar. I think they should all be grid-connected to assist the grid beyond their borders and to make sure that excess solar can be used effectively. Personal batteries assist only the home-owner and any subsidies given by government only benefits that owner. If you're getting a subsidy for a home battery, I think you should be required to take part in a VPP scheme so that the community as a whole gets some benefit otherwise it's just "subsidies for the rich" who can afford to buy them anyway.

I lived in Ellenbrook in Perth in the 2010s, and most nights in summer the power would cut out right when all the streetlights would come on. They ended up running another main power line to boost local capacity but local storage would have been a better solution if it had been available at the time

Rosie, I have another take on the social inequalities. Power coops would be more equitable. Distributed power allows for community coops and individuals to compete with price gouging corporate monopolies, which in turn will lower prices. And, distributed power is more resilient to natural disasters and attacks.

Match the size of the community battery to the number of vehicles owned by the community. Population 2,000. Vehicles say about 1,500. With 100kwh batteries, then 150mWh storage daily.

Community batteries are located in the community. The government paid expansion of the grid to supply the extra electricity loads is avoided but not in the accounting. The failure to measure this saving is a failure to manage our future. I know expanding a commercial building footprint, and its new increased load on the local grid, depends on local grid expansion works. I have worked on such a project that was delayed from even BA approval until the grid operator's work was completed. This was a suburban building, not a greenfield site. More affordable housing will increase community demand. The expanding population of Sydney means expanding demand. Wealthy suburbs buy more Tesla's and other EVs and more rooftop PV. Government pays for the expensive grid expansion. Grid costs are 66% of electricity bills. The grid is incredibly expensive. Suburban land and the environment makes city construction even more expensive. Edit. I commented too fast, Hahaha. You did a great video. 👍 😊😊

An outstanding video again from Rosie. Great overview of what works and what is challenging. Where I live there is an overabundance of Nuclear (when it's running right) and Hydro backed up by coal. I've often wondered why the utility doesn't institute a program to put home (or community) batteries distributed throughout the jurisdiction to store the overnight generation instead of selling it for near zero, and then use that power when it's needed and they right now have to bring the coal online. Combine that with some community solar also in the battery and we could eliminate the coal entirely. Sadly, our government are dinosaurs who burn dinosaurs.

Thank you for the information. It seems like a simple idea that in the future each home or building will have power generation and storage. These building will be connected in groups / units / grids in a smart networks "breathing" in and out storing and using energy as needed.

I think batteries local to the load are a good thing. Yack is doing well. As (chemical) battery prices come down, efficiency goes up and solar adoption also increases, the more likely solution to my brain is micro-grids or self-sufficiency at a household level.

I think community batteries are a key stepping stone to individual batteries. They work by allowing customers to store the excess power their solar panels generate during the day for use later on in the evening. Community batteries are usually around the size of a large car in dimensions and can store around 500kWh of energy - that's enough to support about 250 households. 2kWh per household. Now if EVs are 100kwh and parked 23hrs every day then in my street of 30 homes and 60 vehicles we have 6,000kWh. That is 3,000 households. Thats 100 times the streets recomended needs. Naturally the home robotic vacuum cleaner and the selfparking EVs will plug into the grid 23hrs every day. Infact the EVs could plug into the grid anywhere there is a cheap wall plug at a car park space.

Thank you for the update on how mass renewable energy projects are massively delayed because National grid connection take years! The real estate we need for net zero is available now! No environmental checks! No public complaints, no grid connection delay and fitted and running in 2 weeks! Home solar and storage is easy fast and relatively cheap. Community storage is ok but what about the storage community, 10k homes with 10kw storage batteries the grid can access when demand is high. Need to stop thinking big, instead think small but plenty...

What I think could prompt some more community based energy solutions would be the ability to easily self generate their own fuels. Imagine decentralized small-scale fuel plants that could be community owned. It could really keep a lot of wealth from being siphoned out of smaller centers. Sadly industrial fuel synthesizing plants are large, complex and expensive builds that generally need economies of scale to financially make sense. But imagine if affordable simplified and low-maintenance modules could be bought where you only needed to supply them with water and power to get a fuel like ammonia which could be either sold as a commodity or used as a backup energy source for the community.

Rosie, isn't the key question, aren't these community batteries technically feasible? Whether the government and the utility stitches up the consumer is all about how the community battery is structured in that locale. I have a large amount of excess solar eight months a year. If I were to put in a charger at the end of my drive and make it available to the community in a way that solely benefitted the needy, isn't this really what we are talking about when we say 'community battery or charger'? Then a larger group within my community might expand the same concept more widely. All this is technically possible and need not interfere with the national grid in any significant way, or have I misunderstood?

This could be a valuable piece of the puzzle, especially for reducing the needs for transmission upgrades in hard to build areas. And grid scale solutions are still going to be needed for large commercial and industrial uses. And each project needs to be chosen and designed to fit the problems that exist in a specific situation. off the shelf components, yes. Off the shelf designs, no.

I don’t know, if you have just identified the major problem with the community grid system as bad demand management perhaps talk about the costs and problems of fixing that rather then reaching for more technology. Change the off peak times on the water heaters to the middle of the day or install smart meters to trigger the heaters at time of maximum supply. Thats a much more sensible solution then installing a battery or dam to heat water in the middle of the night. Then see how much missing power the town needs.

Excellent. This can be faster than EV roll out. And decades in front of nuclear electricity. Grid protection and not the incredibly expensive grid expansion to carry the increase in electricity as fossil fuels are phased out. The existing fossil fueled generation can be UNLOADED, and their lifetime extended. In the end, the community battery can be part of the rapid charging infrastructure at the corner store and on the main roads.

Excellent Rosie - if you see this taking off - Interview Lisa Daniels in the U.S. - She is the lead of community renewables here.

It's really frustrating constantly hearing about talk of reducing carbon emissions from electricity generation, but none of it includes nuclear energy. To be clear, I love cooperative and community solar, as well as cooperative and community wind energy. I actually want to by share in a solar or wind energy project myself. With that being said, places like Australia (not including Tasmania), most of the US, the UK, India, China, Japan, Germany, Denmark, Greece, and so many other places aren't blessed with massive hydropower resources to balance the grid during the night when the sun isn't shining, or during periods of dunkelflaute. As demonstrated in Brazil, Quebec, Tasmania, New Zealand France, Sweden, and Norway, cheap renewable sources like wind and solar are great because they can displace demand from hydroelectric dams, and save water for periods when it's night or during dunkelfaute. Nuclear power plants are inflexible, but they also work to displace demand from hydropower plants. Both nuclear *and* intermittent renewables are great because they can be backed up by hydropower, but talking about solar and wind as if they're the be-all and end-all is unhelpful and unproductive. Australia has emissions that are absolutely out of control. Really, Australia should be establishing a nuclear energy industry of its own, and replace its coal/gaspower plants with nuclear reactors. Large traditional nuclear reactors. None of this SMR bullshit.

Oh when I read community battery in the video title, "tragedy of the commons" promptly came to mind. But it was not so - this is more akin to distributed storage.

The price of batteries in terms of MWh are insane, compared to the sheer MWh demand on the grid. Acknowledging that prices have fallen 90+% over the last 3 decades does nothing to acknowledge the material demand & economic cost to implement the volume of MWh to reliably back the grid.

The right question why do we need big plants as industry collapses ?

Retaining grid connection is like having a big battery backup when the micro grid needs help or can supply extra to the grid. Can be like a system that transfers your home electricity to your EV plugged into the grid at work, or at the shops, or anywhere.

Aside from community solar and batteries, is renewable propane an option for communities that want to go completely off-grid? (This would be for occasional mid-winter use.) Another option for consumers with V2G would be to use their EVs to import power during the winter (e.g. from public chargers using hydro power).

Power to the people. Right on.

I'd like to know if it's possible to simply buy my neighbours excess solar? My house has too much shade for solar

Seems to me like community-scale batteries fall in an odd in-between zone. Factories pump out tons ready-to-use of home batteries, and there is little overhead otherwise. You just wire them in and you're done. Maybe you can even do much of the work yourself. Grid-scale you're looking at a ton of planning, managing, heavy-duty equipment and so on, but economies of scale make it affordable. At "community-scale" you're running into much of the same challenges as grid-scale (e.g. securing the installation), but you don't get the benefits of being large scale. No wonder the price per kWh is pretty high for this type of installation.

from: @3rdrock: >Why heat water at night, when you have excess power in the day? Indeed, this legacy thing of running water heaters overnight needs to be stopped today. To my thinking, the best and cheapest use of PV-generated electricity is to power water heaters during the day; then space heat, depending on the weather that day.. Hot water IS a means of storing energy, and there are no signs that humans will stop showering or washing clothes or dishes any time soon.

Grid stability and daytrading of excess might be valuable.

Excellent! Community batteries could make areas more independent of the grid, which has to be good. Will we ever reach the time when there is a battery bank in every electricity sub-station to store power locally and distribute it when needed? Governments seem to be favouring large grid batteries rather than encouraging local batteries. BTW, the Sunshine Coast Regional Council bought a farm and installed a solar farm and now meets its own electricity needs.

Every Substation should have a battery?

Bioenergy technologies, if applied intelligently, can go a long way toward getting community-scaled grids up beyond 100% local supply, both for generation and storage.

Good takeaway: Nothing is foolproof. Specific conditions and implementation can make all the difference. Independence from the grid is great, but for the climate, and other fossil fuel related aspects net reduction of fossil fuels is what's important. Not using any fossil fuels at all directly, for a specific thing, like electric power, for an individual, group/community, is more about that warm fuzzy feeling, than reducing real world problems. Not saying it's bad, it's great, but the goal of freeing oneself from the guilt of using fossils fuels completely, for electric power only, isn't as heroic as it might seem. Transitioning from fossil fuels is still great, even when it's partly/selectively. Subsidies have a tendency to benefit rich people more than poor people regardless of sector. Somehow it's more provoking if the subsidies are for something that benefits the environment. Look it up, most countries gives huge amounts of subsidies to companies, directly and indirectly, and it's not a secret, it's often "hidden" in complicated wording and structures, but most of it is legal, and not technically secrets. I'm obviously primarily talking about representative democracies. I mean, somehow people in general aren't very upset by the huge subsidies that goes into fossil fuels, but subsidizing clean energy that clearly benefits anyone without an interest in fossil fuels, that themselves use energy, and even anyone that breathes, makes some people extremely upset. The subsidies toward fossil fuels are officially intended to secure energy supply, usually/mostly, which I find ironic as the more fossil fuels we use the more urgent stop using them gets, and the faster they become difficult to supply in such huge quantities. The latter should be important even to climate science deniers. The mere fact that fossils fuels requires so much subsidies, despite the fact it's been "powering the world" since the industrial revolution proves they're unsustainable, even besides climate and other environmental aspects. Lack of technically viable options isn't the biggest problem with the transition from fossil fuels.

So, lets completely ignore the source of the renewables. The mining/refining/manufacturing/distribution of those pesky materials that we take for granted so the community can say FU to the grid. What a total fantasy? This comes to a end, real quick, when industrial mining and manufacturing is shutdown.

It doesn’t work, SA and ACT are great examples, proponents use the net energy arguments to be misleading the public, but they are dependent on fossil fuel most of the time. Gas turbines and nuclear are needed if coal fired power stations continue to go offline, as batteries and pumped hydro don’t have enough grunt to run cities.

i dunno if its more the smile or the accent but I'm in love with Rosie.

Thank you for a fair and balanced look at this topic! Ironic that when everything is sorted out…humanity’s vulnerabilities are best solved by community cooperation and coordinated efforts!

Why do you keep deleting any links I post, Rosie? Isn't this meant to be about science?

I have received nasty-grams from YT over posting links. It is most probably not Rosie who deletes your links.

Yeah maybe. But last time when I said “How dare you “ about Rosie flying to Europe, I think she deleted it because I got a notification from YT.

Great. One more tool in the HOA kit to bully homeowners

Grids are 66% of the power bills. 300gWh daily is our Australian avg demand, with peak generation capacity at 600gWh daily if you are lucky. 300gWh x $0.43/kWh = $130million daily. Plus $20million connection fee daily. $55 BILLION every year. GARRENTEED cashflow. NOBODY understands the size of the existing national transmission grid to 20million buildings and millions of ends to the grid. This engineering fact of concentrated electricity generation is totally ignored. Snowy 2 , a $2billion project is now a $12billion project. Smoke and mirrors from vested interests when people talk about the stuck tunnel machine. The original tunnelling was to be done inside the $2billion tender. The extra $10billion is the towers and wires across rugged terrain to distant electicity supply and users. The poles and wires are the real story to our energy future. Even the nuclear promoters attack grid costs for 'free' electricity. GRID COSTS are the UNSPOKEN cost with all centralised concentrated electric generation. Dispersed generation and storage on the existing national grid has this killer economic advantage. Talk about the real grid costs and particularly in a no fossil fueled future world. 5times more electricity is 5times more grid capacity.

Good to see you touched on some of the social impacts of this ‘transition’ (akin to a botched gender transition) cause transitioning is very fashionable these days. Though it's not community-owned, Coober Pedy is an interesting example of a stand-alone system - power prices are so ‘cheap’ that it needs to be subsidised by the state and the cost of the project was a contributing factor in getting the local council into debt. Most of the residents and businesses complain of the high prices - not good if you want to protect people from extreme heat. Solar and wind make electricity expensive unless you own the infrastructure yourself. Nuclear is expensive but makes electricity cheap.

This is a monster development, ironically enough.

Fast and very confusing. No definition. Few details. So much generality. Good topic, but needs more focus

There is a lot to like about community energy and the economics are great. Yet it shall never be more than a niche because it involves people willing to give up a bit of their independence and personal control for the benefit of all. The problem of the COMMONS all over again.

The tragedy of the commons is a bit of an oversimplified model, like most things you learn in econ 101, there's actually a lot of nuance to it that you learn in econ 201, 301, and a graduate program. In the classic example, you get rich people with a lot of sheep over grazing the land because there are no rules over who uses the commons for grazing, but a piece of technology that's built and owned by the community cooperatively would have rules about its use, and in fact could be programmed to enforce those rules in a way that everybody agrees to in advance. It's not really the same situation at all.

Community solar is likely to work better in collectivist societies than in individualist societies such as the USA. The "Lone Ranger" mentality here is partly what got private power generation going in the first place. To now expect dozens to hundreds of Lone Rangers to play nice together requires a stretch of the imagination.

as someone that lives off grid i have found solar is not green technology it lasts at best ten years at Peak output and is not fully recyclable and lets not forget the batteries

Yackandandah is not off grid. Most electricity is generated during off peak hours by rooftop solar which is heavily subsidised. Backup is provided free by the grid. This is essentially a parasitic system creating most electricity when it’s not needed. So the township receives exactly the same mix of wind, solar, coal, gas and hydro that everybody on the NEM receive. To go off grid and supply your own backup and FCAS would incur an astronomical cost per household. Dumping surplus off peak electricity and getting free backup is unsustainable and when coal and gas generators are gone backup costs will skyrocket. The whole concept of a cottage industry being cheaper than large industrial despatchable generators is ludicrous and invokes the Luddites.

Nordvpn ad was too long. Gave up on video.

If it uses batteries, it is a stupid notion!

Community Energy is NOT "power to the people". Administration is a headache. Conflicts of authority are frequent. Far better to promote individual solar systems.

Thanks!
