100% clean energy is decades away, I'm not such a pessimist to presume we will have no grid improvements by then. Marketplaces themselves are already straining due to the cheapness of renewables at certain times. Batteries plus renewables will avoid some of this, but overbuilding capacity and demand response with EVs and industry should be another component. I also expect utilities to buy access to appliances and heating and cooling and dynamically control their customers' use.

I really, really don't want the power company to control my thermostat. Big companies are invading my home and violating my agency enough as it is. If past behavior is any indication of future behavior, smart appliances are more likely to be snuck in like the phone-home misfeatures on smart TVs than they are to be a willing contract between the home owner and the power company.

There is another approach that could also alleviate some of the pressure. Instead of keeping the consumer price fixed and allowing the utility to control your load, you can allow the consumer price to float.

Most of these markets have a 24hr-ahead clearing price for energy. I think you aught to be able to expose retail consumers to fluctuations based on the day-ahead market to let people make their own choices for energy usage. Given that exposure, enough consumers will change their behavior to soften the variability in price. It might also make distributed energy storage Just Work (TM) if individual battery owners have a vector to profit from supporting the grid.

In the USA I thought the price already floated based on market rates.

Yes, absolutely this is the way to go. It works well for gasoline, for instance.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by brandmeyer on Tuesday July 02, 2019 @01:18PM (#20337224)
Retail consumer prices don't float in most markets. Some markets have time-of-use pricing for some part of the year, but even those have a fixed peak/off-peak rate that is fixed well in advance.

What prevents an electric company from significantly raising prices for a day to catch people off guard? I can't exactly switch electric companies to punish them.

Isn't that basically what Enron did to California? Theoretically they are already doing this, just not to retail customers.

You can't switch electric companies, but you can choose to switch off your load (or increase your source), thus denying them revenue or increasing their payments to you.

It also gets harder to game this system as distributed generation gets better penetration. The optimal thing to do as a residential energy provider is also naturally stabilizing for the grid. If a cabal of generators acts to restrict supply and artificially raise the price, then everyone who isn't a member of the cabal makes a killing selling energy into the market.

Its also hard for a cabal to squeeze residential providers out of the market through lower prices. Distributed generation is a small fraction of any individual provider's income. In most cases, a residential provider is paying for their system over several years. So in order to squeeze them out, a cabal would also have to sustain a campaign of artificially low prices for a span of years in order to have an impact.

Distributed generation means that there is a pool of small independent suppliers whose rational choice always acts to counter the actions of any oligopoly that attempts to form.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by brandmeyer on Tuesday July 02, 2019 @01:50PM (#20337585)
There are other futures markets that are bootstrapped off of the day-ahead market. Weeks/months out are used to schedule maintenance operations. Years out are used to schedule construction/decommissioning.

So if the extended market prices are high enough, then this acts as a signal to add generation and/or distribution capacity. Likewise, if the extended market prices are low enough, this acts as a signal to retire capacity that has a higher operating cost/lower profit margins.

Nest partners with utilities to support demand shedding/load response [1]; you get a utility bill credit for allowing the utility to send Nest demand shedding signals when local power demand is high (which suspends your AC cooling cycle for 1-3 hours), but you can override the thermostat setting if you must (you just don't get the credit). Cheaper than firing up a single cycle gas peaker (super expensive, comparatively speaking to base load and renewables).

You don't have to allow the utility to control your consumption automatically, but then you'll be exposed to the real time price of power (not a regulated average as occurred in the past because of dumb meters).

I have this on my nest, and one interesting feature, is it turns down the AC to a lower temp a few hours before the 'energy rush hour' so that your house doesn't get as warm.

IE, I have it at 72 deg, a 'energy rush hour' is declared, the nest automatically turns my thermostat to 70 deg an hour or two before, then to 75 deg during the rush hour.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by HeWhoLurksLate on Tuesday July 02, 2019 @12:37PM (#20336781)
So then could I hook up a load to a Nest and have a regular, dumb thermostat control my house and get those credits without actually doing anything? That doesn't seem too hard to pull off.
Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by grimjack00 on Tuesday July 02, 2019 @12:43PM (#20336855)
Until the utility upgrades to the next version of demand response software, which notices that you were sent a control message, but your consumption didn't change, so you're no longer eligible for the credit.
Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by solarkraft on Tuesday July 02, 2019 @02:58PM (#20338268)
Then your electricity will probably be more expensive than that of the people who will utilize the night's cheaper rates and will get rebates for installing a device that will turn some devices down on unexpected peaks.

If you still "really don't want the power company to control my thermostat" after seeing your potential savings, that is.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by ThomPete on Tuesday July 02, 2019 @11:54AM (#20336310)
It's centuries away.

So much legacy technology and machinery, buildings, installations, infrastructure not to mention the fact that neither wind nor solar and not even hydro are anywhere close to being able to provide that it's only a few percentages of world energy usage and have upper limits.

In my view the only real fundamental progress when it comes to energy, within sight (and it's still far away if ever) is Thorium and Fusion.

Furthermore the externalities of things like wind and solar isn't calculated today and would make two things very clear. You can't have wind and solar without the backup of oil/nuclear/coal and they will never be able to provide us with enough energy to meet our needs to not talk about meeting our future needs (which will be many times higher than it is today)

I am all for green energy but i share your pessimism.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by telchar on Tuesday July 02, 2019 @12:45PM (#20336874)
Grid power distribution itself is barely more than a century old, and you think it will take several times that to adjust to a mix of different power sources, despite that being already well underway? On what basis?
Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by ThomPete on Tuesday July 02, 2019 @02:25PM (#20337934)
Because it's too expensive at the end of the day.

The more wind/solar you build, the more backup from coal/nuclear/wind you will need.

But the way to make us all better off is to make energy cheaper. There is a 1-1 correlation between energy usage and then rich, advanced, safe, clean and flourishing societies.

Wind and solar will only go as far as the political goodwill will take them. They are IMO unfairly promoted and that will incur a cost on their fundamental ability to be a solid enough energy form IMO. They are great as plugins to the existing system but the idea that we should build a smart grid because of their inabilities to provide on demand is not sustainable at the end of the day.

So my basis is based on part speculation, part knowing the limits and true cost of wind and solar and other alternatives.

Only Fusion or Thorium or maybe if we are lucky, fuel cells, will be actual progress which will also be economically viable. But this idea of a giant mix all handles by a smart grid is the not how it's going to play out as the upside of the usual alternatives simply aren't enough to outweigh the downside of cost and complexity they will incur on society.

But it's just my personal opinion of course. Each to their own.

At current rate of adoption it may be centuries, but I'm willing to bet that by the end of this century (possibly earlier) there will be a great deal more public pressure to revamp the underlying infrastructure. We could do it in a few decades if we decided to spend the capital on it, its ultimately a question of political willpower.

I do agree that fusion would be the ultimate form of power generation and would have the least impact on the current grid. But regardless, the future of energy generation is in diversity of sources.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by ThomPete on Tuesday July 02, 2019 @01:03PM (#20337071)
There already is pressure today to do that. However, I am unconvinced it will actually get done on any significant scale unless there will be fundamental improvements with regards to energy sources. Otherwise, fossil fuels are simply going to be too valuable in no small part due to its multiple applications which none of the other types of energy provides.

Otherwise, it will come down to economics. So I agree we will diversify but fossil fuels aren't going anywhere anytime soon.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by headcanon on Tuesday July 02, 2019 @01:32PM (#20337370)
Honestly I don't even think it would be as complicated as all that. Its all down to what becomes more valuable. Here is a breakdown of energy generation in the US:

https://www.eia.gov/tools/faqs/faq.php?id=427&t=3

63% of power generation comes from "fossil fuels", but half of that comes from natural gas. If we focus purely on carbon emissions and ignore implications of fracking, natural gas can be considered "clean". Also assuming all renewables are zero-emission, this means roughly 30% of our power generation has the potential for carbon emissions.

By simply instituting a carbon tax, or even requiring coal plants to sequester emissions would make burning coal expensive enough that other forms of power will become cheaper, and thus the market would align appropriately. These are things being talked about right now, so its not unrealistic. The coal lobby won't like this of course and will continue to push us away from that, but I believe in 50 years when Miami and New Orleans have turned into Venice and the new generation of people won't be working in coal, American conservatives, as well as other nations, will stop complaining about the coal industry so much. All that has to happen is a few percentage points in a certain direction and the machinations will start to work.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by ThomPete on Tuesday July 02, 2019 @02:25PM (#20337930)
You are looking at electricity generation, not energy. Electricity production is a subset of energy and that's kind of my point.

We get these rosy images of how far we are with renewables when in reality once you dig into it you realize we are nowhere near anything that can replace our current primarily fossil based system.

We don't appreciate how much fossil fuels are making our lives more livable and how little alternatives add to this livability.

I understand the potential CO2 emission risk etc, but we are safer because we use fossil fuels, not despite of it.

And we are not just talking for energy here, we are talking plastic used in more or less any industry you can think of from healthcare to textiles to toys. We are talking for greasing, we use it for fertilizers which makes it possible for us to produce the amount of food we do etc. Which means that oil will play a very very very significant part of our lives for many centuries unless of course some completely new material shows up with as much versatility and application. And now that we are drilling for the oil anyway....

I understand that this isn't what we want to hear, but that's the reality and there isn't currently much of an alternative.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by headcanon on Tuesday July 02, 2019 @05:32PM (#20339596)
Yes, my statement was purely scoped to emissions, and using fossil fuels for electricity generation, as well as powering vehicles. If fossil fuels weren't useful we would of course not continue using them. Hydrocarbons will of course continue to be used in various materials.

However, for everything we make in plastic, there is a potential alternative. In many cases that alternative is more expensive than plastic for its specific purpose. Much of the reason plastic is cheaper is (conjecture here) because it is subsidized by fact that we use so much oil for energy. If all (or most) cars were electric, demand and production of crude would go down, and so would the economies of scale, possibly making plastic more expensive than biodegradable alternatives.

People will continue to use the materials that are cheaper. However our economy is not set up to internalize the costs to the world and to its biosphere. In that sense fossil fuels are very expensive, and we are incurring a debt. At some point its going to be time to pay the piper, and the alternatives will become cheaper by comparison.

Re:US Electricity Markets Aren't Designed to Handle 100% Cle... by ThomPete on Tuesday July 02, 2019 @11:27PM (#20341368)
It's not a question of whether there is an alternative it's a question about what we are using plastics for.

Plastic today is a highly versatile material it can be almost as hard as diamonds, it can be ultra precise like lego and so soft it's weaved into our textiles.

You've seen the sorry substitutes for straws? They can't even make that.

You won't find alternatives for that and again ex. wind and solar are subsidized without providing any of those benefits.

You last comment is speculation and your conclusion even if it was true isn't the only alternative. There are many others. Some of them include us developing methods to deal with CO2 if it turned out to be a problem and you are forgetting the most important thing here.

People who don't have access to cheap and plentiful energy are already incurring a debt to survive and paying the piper. There is a cost to NOT using fossil fuels, one very few are ready to make. I for one am not ready to exchange things like food security for the risk of some speculative consequences we dont even know and to the extent we know isn't something we can't deal with.
