That said, get acquainted with:

- How the electrical grid works. You will at the least want to have a working understanding on how generators synchronize to produce a coherent grid and how frequency regulation works. You should be able to at least immediately tell the difference between a MW and a MVAR, or to clearly explain the impact of power factor correction on transmission line capacity.

- The various different primary energy sources (fossil fuels, nuclear, wind, solar) and how they differ.

- Your local electricity grid regulator will have published rules for the local wholesale electricity market. Learn those and how to interact with them. You should probably be aware that for most markets the minimum bid size is in the order of megawatts, which is enough for about a thousand homes.

- The economics of how power generation works. Power generation has massive economies of scale and single-person initiatives are unlikely to be able to compete.

- Last but certainly not least, get yourself up to date with safety regulations. Grid level electricity will not only kill you, it will hurt the entire time too.

If you want to "just" make enough electricity for yourself, get some solar panels on your roof. I'm sorry this post is probably not what you were hoping for but electricity is really really dangerous and not something you should be going into if you don't have a firm grasp of what you are doing.

The only "in" for a small player is remote/rural where the cost of distribution infrastructure dominates. Also dispatchable service to provide frequency stability seems to be a niche.

Even then, you still have the same high cost for distribution infrastructure (actually higher once you factor in economies of scale) with none of the experience building said infrastructure. And you're probably not going to be able to build an isolated grid because (at least in the US) power companies have already run wires basically anywhere people are willing to pay for power.

The biggest market I can see is neighbors pooling funds for a large solar installation and wiring up everyone's houses to reduce power bills, but that would probably be a permitting nightmare (and that's assuming there's no legislation prohibiting this already).

Building-level electricity is the type where a dropped spanner instantly becomes a faceful of gaseous metal. If you think you have time to feel the pain, you don't understand grid level energy yet.

Yeah, was about to say - grid level arc flashes don’t even require being particularly close to a conductor, let alone provide enough time for the miscreant to feel pain before becoming chunks or vapor.

It can leave cool scorch marks though!

And for reference, a MW of Solar panels costs close to $1M - so this is not really a feasible industry for the average Joe to enter.

People would take out loans to afford them, or rent them from the real "franchise owner".

Not everybody aspires to a unicorn exit. Predictable returns are worth a lot too, even small ones. The drivers who took out loans for their medallions really got screwed when Uber came in, but if the demand for electricity drops catastrophically, we'll probably have bigger problems than a bit of debt.

2) you might need to have 10x that much (in just panels).

3) I'd be amazed if you could find financing for this.

It might look more like a micro financing idea than a franchise. Most of the commercial-scale solar installations today are built by a developer and then either a) held in their portfolio or b) sold to a utility

Earhart had been a pilot for eight years before attempting to cross the Atlantic.

The only exemple of someone entering a highly regulated industry without being an insider I can think of is Musk and SpaceX and even then he was previously rich, started by building the connection which would allow him to get public funds through the Mars Society and his first move was hiring Tom Mueller, an industry insider.

In my experience, people with a software background who don’t have an industrial background heavily underestimate the complexity involved.

Yes, there are specific parallels to the Wright brothers - if you want to make and fly a plane exactly like the Wright brothers did, well, you can't simply do that anymore, you need to follow FAA regulations and safety standards which didn't exist back then; and recommending that someone "just do it" would be irresponsible.

For example, with an ultralight you do not need any sort of pilot's license or medical certificate.

EDIT: Actually the wright bros aircraft would be too heavy to qualify as ultralight nowadays. But with today's materials I'd bet if they did it again they could get it under the weight limit.

See also: those "crazy/wacky/funny laws in <city/state/country>" books and listicles that feature antiquated laws that are still on the books (some of which are most certainly unconstitutional) but nobody cares about enforcing them, so there exists no political will to repeal them.

Civilization has had grid scale electrical power for over a hundred years. It’s sheer hubris to ignore the fact that this is a mature industry with experts that have studied the problem for decades.

Not to me tonight your examples are a bit off. This is nowhere like the first powered flight. Earhart when missing swing her risky thing and was never seen again. Edison intentionally extracted large animals to drive artificial fear over the safety of AC, not to mention many of his most famous inventions are considered to be the fruit of his employees rather than his own intellect.

Also, the people you cite had expert level knowledge in their field when they built novel projects; they weren't asking beginner questions on HN.

You really need to do a lot of research to figure out if it's feasible and if you have enough sunlight, area for panels, etc. to make it worthwhile. There's a lot of upfront costs too with the panels, meters, and extra protections necessary for when you're interfacing with sending power onto the grid--a lot of folks need to run their system for 5-10 years or more before it breaks even and starts making them money vs. all the initial costs.

I could do something economically productive with the billing credit, like charge EVs or mine crypto, but I consider that more a knock-on effect than a moneymaker.

[1] EU; I gathered that solar is significantly more expensive in the US.

You put some modern panels on your roof that absorb power from the sun that now no longer gets absorbed by your roof - so your roof is now a little cooler. A wooden roof is now actually less of a fire risk and a tiled roof will now absorb and radiate less heat - bonus!

I live in the UK. We build from sticks n bricks. We've had a bit of a heat wave recently that concentrates the mind somewhat. My office (I'm the MD) has a vast expanse of red brick double skinned which is south facing. My desk environment is around 10C warmer than the external temperature (I have a lot of sensors deployed). I have now decreed that when my desk temp is 30C then we abandon ship and work from home.

I'm going to investigate skimming the red brickwork with a white render. My parent's house is a modern build and that seems to help.

Oh, fire risk? What on earth are you on about? Insurance risk? What are you on about?

Adding a whole bunch of electrical equipment (that's exposed to the elements, wildlife, etc.) absolutely increases the risk of fire. Panels are heavy as well, so you're increasing the load on the roof, could increase risk of collapse (especially in areas that get lots of snow). Plus, if you don't notify your insurance company, it's at best not going to cover replacement cost of panels if something goes wrong and at worst invalidate your whole policy.

I trained as a Civ Eng in Plymouth (the British one). I now own an IT company. I have a fair idea about fire risk (I'm our fire officer too) and how some materials behave in general and under loads and incident (eg fire).

In my opinion, roof mounted solar panels have very few risks in the UK. The likeliest risk is wind related. We are seeing increasingly strong gusts - virtually nothing compared to tornados but this is a land that does not have tornadoes (yet).

We need to consider surviving Beaufort force 12 as a minimum standard.

https://www.bbc.com/news/education-33136737

Easily said but ... don't

Properly installed? Sure, no or minimal risk.

But insurance companies deal in aggregate, which includes improperly installed panels.

My understanding is that the legislation actually requires the working environment be cooler than that, so I get the sentiment, and ironically probably many of your employees' homes will be hotter, but I think you've set the bar too high.

I am the H&S bod, and shortly I'll be first aid accredited (again). Mind you I've done first aid for sailing and skiing back in the day too, so I know what you are supposed to do when hit by an avalanche ("swim" and pray, or soil yourself and pray - which is more likely) and how to treat or at least mitigate hypothermia.

For some reason we have had loads of practice in working from home recently. I'm an expert in VPNs and all my staff have home phones virtually wired up to our PBX.

The other 75% of solar energy heats up the panels themselves I guess and/or is reflected.

The stats showed that the rooftop isolation switches shorting out was the leading cause of fires. We no longer fit them.

"More than 90% of inspected rooftops had significant safety and fire risks. Here’s how to protect your solar asset."

Lots of bad wiring. Get a 3rd party inspector.

May be best to watch the inspector do the inspection?

More electrical systems in your house means more risk of fire.

Pre the latest increase today 'leccy costed around 30p per KWH - after today it will be at least 45p. 7.5p for self generated is nice but I suggest you use your own generated power.

If you really do want to operate a business generating electricity, start by learning how the power market operates in your area. Unless you live off-grid with a high degree of autonomy, you're likely to find that there are zero opportunities for an individual to enter this market on their own. Providing stable power to the grid requires unbelievable amounts of capital, planning, compliance, person-hours, and way too many other elements to list here.

If what you're actually interested in is generating electricity for yourself or your community, the good news is this is much more approachable. Developing and operating small-scale off-grid renewable energy system for a small home is achievable with off-the-shelf components and a basic understanding of electronics. You'll still want an electrician to validate and perhaps perform some of the work, but it's all pretty basic.

If what you're actually interested in is spearheading a renewable energy campaign for a large community currently dependent on other forms of power, take a look at community solar programs and energy cooperatives. Both are in practice all over the US.

I kind of want of something in between the first two potential interests. Imagine something that is like a cross between a solar panel and a night light that you plug in to an AC outlet, but that plays nice with the local power grid in every which way. Sure the amount of power it could produce would be negligible, but being able to create something that is able to feed the grid and meet all appropriate regulations for the electrical code would be an accomplishment in itself. I don’t know what the physics and capital costs behind creating something like that would be or if this idea absolutely infeasible because of the same physics and capital costs, but that is also what I am trying to learn. I am also not married to this idea at all: it is just an illustration of my level of knowledge on the subject matter as a whole, and the kinds of questions that first come to my mind.

For what it’s worth, the scenario you describe is basically how the state of the art home systems work in the markets that support them. Distributed generation (via solar), energy storage (via batteries), and bidirectional grid connections for feeding surplus energy to the grid. Some companies even aggregate homes to act as a virtual power plant which can be dispatched on demand. There is a ton of interesting stuff happening in this area, I hope you find an opportunity that suits you!

2. There is a tariff for interconnection, and you need anti islanding. Inspections are backlogged by 6-12 months in the area. You’ll need an electrician to draw up the plans for submission to Centerpoint.

3. Even though Texas’s power market is famously “unregulated”, it’s still very regulated. I recommend starting here: https://www.ercot.com/services/training/courses/details?name...

ERCOT has a wealth of information available so that you can get up to speed.

That said, my approach was to find businesses or individuals as near as possible to a given piece of land (a lot I own) and see if they would buy power directly from me. I also contacted the local utility provider (as other commenters suggest) to see if I could sell them power or lease them equipment or land.

The idea was something like: find a large power consumer nearby - someone heating a hot tub, running a woodworking shop, data centre, whatever; undercut the local utility, see what the payback period would be on the capital equipment, then get a legal consult on how to paper it, then hire electricians to hook it all up.

tldr I suggest validating the market first.

Becoming a solar installer and engaging in some kind of revenue sharing or a loan kind of structure for getting residential or commercial customers in on it.

Building solar powered vehicle charging stations.

Building backup generation facilities for things like data centers or hospitals.

So get on a roof and put solar panels on, you can do it! Fall off? Relax! Fall on the bouncy castle, sprained ankle at worst.

And you align solar with the future, which is to say the children.

OP please steal this idea. Please. Never give me credit, I just would love seeing a pamphlet saying "bouncy castle solar" on it, ideally handed to me in an inconvenient time and demanding my attention rudely. That level of success.

More progressive installations and new builds can just go 100% DC and drop the AC and the grid entirely. Whether this is appropriate is case-dependent. It's easier if you cook, shower and heat with gas. This obviously restricts internal design decisions but is totally possible, provides better results, greatly reduces regulatory overheads and safety concerns and is closer to what we see on cruising yachts which often have combinations of wind generation, solar generation and propeller-based generation.

Another concern is energy storage methodology. If you are building a new site you can consider interesting storage technologies such as buried flywheels vs. batteries. Some of these techniques will cost more up front but function far longer with far less maintenance. Fossil-fuel based generators are a good backup option. You really need to profile the loads in terms of peak and continuous draw plus cycle time and frequency before specifying storage.

Note that distribution cabling is expensive. Both copper and aluminium are going up in price and even at wholesale rates here in China heavier gauge copper cable is USD$1.5/meter or so (bare). Cheaper aluminium cables cost about 25% of that but Al is brittle and develops resistance over time owing to surface oxidation, contributing to the probability of delayed failures.

You could start with reading your national electrical code and national building code to understand the installation applicable regulations.

If you are an an electric deregulated market:

- Utility commission (PUC, etc.). They will typically have a lot of sway in your day to day.

- Retail Electric Providers: companies that operate as hedge funds and try to buy from you cheaply and sell to customers on a spread

- Aggregators: aggregate customers that purchase energy as a bloc

- Transmission & Distribution: the wires folks

- Power market: your area will vary, but this is an open market where you can sell. Typically you'll sell forward or futures contracts of a sort. There is often a day-ahead market and a real time market as well to help plug any gaps. A power provider that can spin up quickly does well here. Someone with a bunch of airplane turbines can also help here when supply > demand if they wire their turbines up (turbine = generators, backwards). There is a lot of creative financial focus in this space since the returns are more apparent than in power generation

Without it that access, you are likely going nowhere even with a small commercial solar farm.

Think about the supply chain. Is there a consumable which you could source and supply at better margin and lower cost? Is there a niche in replacement china insulation pots for the posts and wires? Can you make a better self tensioning high current wire connector?

Think about software. Is there a gap on demand management, software for power monitoring, weather prediction.

Do you know enough about it, to take baby steps?

Do you have some examples? I think those that were successful despite not knowing anything had other advantages, as the parent is saying (a lot of money, some friends, some expertise in some other field that was applicable to this problem...). So I think it's a fair question.

2. Find land that works for building your plant. It should be near existing transmission or distribution infrastructure so you don’t have to build as much yourself, which is expensive, and it should have good road access already, so you don’t have to build as much yourself, which is expensive.

3. Get a connection study done by the utility which proves it is possible for them to accept the energy at the ___location you want to build your plant

4. Sign contract to sell your energy

4. Get environmental studies done to prove you won’t harm birds fish insects etc

5. Get financing and insurance

6. Contract out design and construction of your plant. Probably operation too.

The technical side is the easy part. Getting the contracts and permits in place is harder.

Under capitalization is most likely to bite you. That’s true of all business.

Good luck.

Something like a microcontroller based remote weather sensing node, or a garden night-light, powered by a 1-watt PV panel. That has generation, transmission, conversion, storage and end use all in one package. End to end. Very thin. Maintainable by an individual.

A business? Hire a registered electrical engineer who specialized in Power Systems Engineering. Likely, you'll need several, because of the sub-specialties. Lawyers too. This is not 1887. We have a lot of laws about consumer and third-party safety now.

If you just want to learn about generation and distribution, get an EE degree specialising in Power Systems.

Regulation. (Highly depends on where you live, though).

1. Connectivity is an issue that isn't power generation per se but a potential business opportunity. From what I gather, the power grid would be more stable if we had better connectivity and the isolation of Texas from other parts of the US has been a factor in some of their issues of late.

2. Electricity generation is very much an environmental issue. Regulation is a big thing generally, but environmental regulation is something likely to bit you at some point. If you can do something that is so high quality in that regard that it is likely to exceed any standards that may be instituted in the near future, you would have an edge on competitors.

3. Energy storage is a big issue. We are moving towards solar and wind, both of which put out energy but don't create stored energy, unlike historical hydro which dammed up water and thus created a store of potential energy that could be adjusted at times.

4. Both solar and wind are variable in their ability to produce energy. Wind power has the issue that when a big storm comes, they may need to shut things down to prevent damage to the system and cannot handle the potential big influx of power the high winds represent. We are apparently failing to capture a lot of value in that regard.

5. Wind and solar tend to be complementary but I don't know how often they get packaged together for off-grid applications. It's common for it to be windier than usual when the sun is not available (during storms, shortly after dark).

I think there is lots of ways you could create new businesses related to energy. I encourage you to find some means to just start reading, come up with your own ideas of where some of our energy generation pain points are and go from there.

People tend to do more of the same old, same old. If you find some new angle, keep it quiet until you get traction etc, you can potentially make a mint and also go down in history as some kind of hero for solving this. We currently do a lot of hand-wringing about how there are too many people, there are not enough resources to support them, we are doomed, we need to stop consuming so much electricity, etc ad nauseum.

Best of luck.

It'll be a while before you get to the point where you can safely hook up to the grid "DIY", so don't do that. As other posts have mentioned, how the national grid works is fascinating and non-trivial. (I love knowing that stuff, just because I'm a dork)

To answer your questions.

1. Create your own vertical based on your surroundings. There are really only two ways we currently make electricity, spinning a turbine which then spins a generator, and photovoltaics.

A generator can be made from an electric motor. Figure out how to spin your generator and you are making electricity, or buy some solar panels.

2. Be familiar with Maxwell's equations (these equations explain how both generators and electric motors work), how to read and understand loss charts for wiring, College level circuits, and most importantly safety.

3. Learn basic electrical safety and high voltage electrical safety. High voltage safety is different because of the potential for arcing and it can "grab" you.

However, if you can conceivably generate emissions-free power on-demand at a cost lower than what they're paying now, you will likely have hundreds of companies knocking your door down trying to help fund your scale out.

In that sense, a minimal self-contained idea might be to build a charging station. You can build one using solar charging, battery storage and with grid power backup, for example, from first principles.

The solar + battery storage part of the charging station is the power plant and you can build that with existing tech components.

If you are focused on the business aspect of it more than the tech, you can instead focus on becoming an operator by choosing tech (charging stations) that is already available off-the-shelf and instead build a charging network (in a specific geography or market such as residential/apartments/parking lots).

To answer your question on the parts that are easy to dismiss: Focus on the business context, technology, organization, people and process questions. Each of these has a lot of problems and opportunities that you can uniquely choose to address with your company/initiative.

Good luck.

Then understanding battery storage for the solar and integrating this.

You should become licensed to do all of this or be prepared to build a business that employs people to do so.

Next would be to build a solar grid in your yard or buy some land to build on. Then offer to sell it at below market rates to neighbors and integrate your solar grid into their homes.

The end goal being something analogous to a WISP which you could continue to add on to as capital and experience permits.

https://www.wispa.org/what_is_a_wisp.php

https://www.allpowerlabs.com/

Your state probably has a public service commission that won't allow you to compete with the local power company. Competition in the utilities business is illegal.

Or perhaps it would make more sense to colocate with someone already producing such a product and selling them electricity so that you don't actually have to deal with making the product yourself?

I'm thinking aluminum, hydrogen, synthetic hydrocarbons, etc.

I'm completely uninformed, correct me if this is a stupid idea.

Beyond that is extremely costly (capital, labour, time etc). You could look at solar farms or low profile wind energy installs though (e.g. look at improving the wind-type TENGs).

None, you'll want to have an accountant and a lawyer and incorporate your business before you begin to approach your states Public Utility Commission.

Your best bet is taking over an existing hydro-dam, but there are VERY good reasons people don't want to own them.

It's perfectly fine as an outsider to try to break into an unfamiliar industry, even a mature one. But what is it exactly you want to accomplish?

Electrical power generation is a mature industry. So what's the problem with the industry you think you can fix? What's your idea for something that isn't already being done?

Get enough amps from / to the grid.

So what happened in the late 60's early 70's when OPEC, the copper predecessor of petroleum OPEP, in English called OPEC, was successfully cornering the market on copper. And people went apeshit! Like USG said no more pennies because people were melting down pennies. Melt value it's called in currencies. So that's when they substituted with zinc for the inside of the penny--still a bad deal these days because you still need a layer of copper on the shell of the penny, that's a money loser for USG. Speaking neutrally in this case, USG is a neutral term even the US Embassy to Russia uses on its website. United States Government. Anyway. Like USG can lose some money but they can't blow money especially not in the direction of an antagonistic Marxist democratic winner president. So...the pennies got hollowed out--and again those pennies are worth 5¢ still, bad deal, just not a terrible deal like it was before. Could have been worth a quarter, fucks up the whole system.

There is a system. System doesn't want to talk about there being a system, but there's a system. And it needs integrity, which I like to give it, because when there is no integrity all Hell breaks loose.

So that's one way you could win. Do away with all that flamboyant high-voltage shit and do voltages humans can tolerate, like household voltages, just using a lot more copper. Lots more. Take the USG out of your equation, buy copper, hey it's a precious metal, it's an exotic metal, you're clearly not politically aligned with negreating Chile, Peru, Zambia, Zimbabwe, Arizona, and Mexico right? And copper in your wires is a great investment. Copper hasn't had a bull run in ages. Again, very niggardly buyers who through golps of state (coups d'etat), highly negreated commodity. Very political. In fact for copper wire thickness it's not an optimum to use the thin wires they use out there, it's calculated based on interest rates and metal prices, and then there's the political layer. Get wires as thick as whale-hunting rope, six inches diameter, go for it. More efficient at every voltage, can use lower voltage, less liability insurance, go for it. Electricity can't leak onto more copper.

There's caveats. Although you should also do your own experiments to verify, don't get everything from a single pipe because then you're destined to suck it. That goes for electricity generation as well, you can give people options, maybe jump in during a disaster, when too-efficient (not effective) power generators go offline.

And study up. Be an autodidact if you wish, but be solid. Work through like three books, working out all the exercises, with only minor gaps.

OK so you get one of those books from an Elmer, which is a common baby name in the 1890's I think, meaning an old-timer who's seen all kinds of shit. All kinds. And in addition to all that shit of all kinds, seen a lot of the same shit over and over. In Japan people respect this level of repetition, in America no you gotta be a movie star and always do radically different stuff in a single respectable line of business perpertually...forget the American. So in Japan a sushi apprentice must cook rice for ten years before he gets promoted to a chef. That has worth! You end up knowing the rice so perfectly...every detail, the times, the temps, the water, the purity of the water, tap water or non-effed-up water (F'ing as in F the letter for Fluorine). Like I just tried cooking rice and fucked up hardcore, it burned into the pot, because I didn't know the bottom of the rice had charred while the top was soggy.

So get that Elmer.

And then, read those books. And then you know what why don't you verify experiments, read about Tesla's experiments verify them, there's shit going on there, there's political stuff reaching into the physics, it's not flat physics. Know that a friend whose judgment is ground truth said Newton's physics formulae didn't check out. Like at all.

Maybe we're in a Riemann geometry insofar as the laws of spacetime physics.

But in the meantime, be very very independent, find beauty is simply and solely how little resistance there is to verification.

And start strong, get worn out, struggle to death. Then you'll get a second chance.
