Utilities Should Worry; Rooftop Solar Could Soon Cut Their Profit

Lucas123 writes A study by the Lawrence Berkeley National Laboratory predicts that distributed rooftop solar panel installations will grow from 0.2% market penetration today to 10% by 2022, during which time they're likely to cut utility profits from 8% to 41%. Using those same metrics, electricity rates for utility customers will grow only by as much as 2.7% over the next eight years. By comparison, the cost of electricity on average rose 3.1% from 2013 to 2014. The study was performed for the Office of Energy Efficiency and Renewable Energy under the U.S. Department of Energy. One of the main purposes of the study was to evaluate measures that could be pursued by utilities and regulators to reduce the financial impacts of distributed photovoltaics.

    And you think the utilities will suffer because of this? Here in Australia power companies have just started bringing in (opt-in for now) billing at different rates for different times of the day for all a house's power. They will simply make day-time power prices stay the same and increase prices for night-time usage, passing the loss on to customers as they always have.

    Quite naive to think a company would accept the losses themselves.

      the whole thing may either turn around or at least shift toward day-time electricity being cheaper simply because of basic economy principles, not because of some malicious intent.

      We should stop pretending that there is anything like a "Law of Supply and Demand" when it comes to energy.

      And if you want proof of "malicious intent"...

      The Koch Brothers (and others) are pushing these "solar tariff", sun tax and surcharge laws all across the country. The rationale in their advertisements has varied from place to place, but generally it's "Solar energy is costing us money so people who use solar energy should pay double, one way or the other, because screw you, that's why". And yes, it even applies to solar which is not on the grid. So if you want to set up some solar panels to augment your daytime energy use and maybe a battery for night time, be prepared to pay this new tariff because of the Koch Brothers and their representatives at Americans For Prosperity

      They're determined to send a message: "If you think you can leave us and go back to your mother, think again sweetie, or maybe you'll run into another door."

      The difference being that nobody needed buggy whips anymore. People here in Germany still need electricity at night.

      Because of the way the law is written, solar cell owners are allowed to use the grid as a battery. Their electricity consumption/production is not billed instantly but averaged, so that someone with enough excess solar power during the day doesn't have to pay anything for grid power during the night.

      The coal, gas and nuclear plants have to vary their production to take up the slack when wind and solar go down, which is expensive, and it becomes more expensive the more renewables there are. At some points it becomes unprofitable to build, and this is where we are now.

      that legal system for selling electricity was jury-rigged

      That phrase... I do not think it means what you think it means.

      Germany is in the middle of the transition. There are still 10 years to go. Things can get a bit extreme at times, but it's basically working really well. Short term price increases (still not the most expensive in Europe) and increased CO2 in exchange for being nuclear free, down heavily on coal and gas, and up massively on renewables by 2024. It also makes Germany the world leader in renewables, so German companies are getting all that business overseas too.

      Luckyo, you seem to have either not understood or ignored my reply last time, or maybe you just feel butthurt that your cool nuclear tech is being pushed out in favour of hippy windmills and solar panels. I'm sorry you feel that way.

    Utilities are boring because they do a simple job which generates small but predictable profits. Therefore investors put their money into them in the expectation that they will remain boring.

    When a new development comes along that destroys their business model, one of two things will happen; they will increase their prices, or they will go out of business. Note that 'the government taking them over' is a subset of 'they will increase their prices'. The service that they provide; a reliable baseload supply and a safe network to distribute electricity HAVE TO BE PAID FOR. At the moment those costs are hidden in the average cost of a kWh. If private solar power reduces the average demand some of the time, the average cost of a kWh will have to be increased, or the other features be recognised and paid for.

    Ladies and gentlemen, there is no such thing as a free lunch, despite politicians pretending otherwise for several thousand years.

  3. Generation and distribution by jbeaupre · · Score: 5, Insightful

    Utilities actually have two businesses: Generation and distribution. We pay one bill and conflate the two. Solar just makes it clear they are different.

    With home solar increasing, utilities will just invest less and less in generation. The transition is pretty gradual, so they can adapt just fine. Profits from generation will decline ... life will go on. But only if we accept that distribution also needs to be paid for.

    If and until home power storage also becomes economical, homes are still going to need to connect to the grid. That infrastructure will need to be paid for. It's going to be tacked onto the utility bill. In the past, we subsidized small users by paying by the kwh. Now we have to decide if connection fees are more appropriate. That's what the debate is going to turn into.

    Plus there are cases of outright bans on some kinds of solar setups (I cant find a cite right now but there have been cases where people have wanted to install solar panels and a battery bank or whatever and completly disconnect from grid power but have been prohibited from doing so by state and local laws)

    What happens if you don't pay your power bill and they come and disconnect you themselves? If they come and see the solar and have been instructed by company brass to forgo the disconnection in those cases, let the poor (that DO get disconnected) and their advocates know... won't take long before that changes.

  5. Re:cut utility profits from 8% to 41% by dbIII · · Score: 3, Insightful

    Rooftop solar flattens the daytime peak and cuts down on the maximum capacity needed to be produced and transmitted (along wires of course, but that's the word) from other places, so it does eventually pay for itself even when the money thrown at it is excessive. A bit of a problem is that throwing excessive amounts of money around builds political influence, but that's not a solar problem per se. Stop throwing money at it and they'll still be some takeup, especially in areas where utilities are indulging in excessive price gouging.

    With respect, take a look at a chart showing air pressure across your continent. Consider what it means in terms of wind, especially since windmills are spread out quite a bit now. The "wind is always blowing" thing is reality on the scale of a continental grid, even an electricity grid in Europe since there are such large interconnections between countries. If you look at a North American air pressure chart and the size of the US+Canada grid it's even more obvious.
    I've never had anything to do with windmills and don't even like them much but I'm sick of all the politically motivated bullshit attacking anything in power generation that is seen as remotely "green", and that's why I called the GP poster to task for his bullshit.

    In general, that is indeed correct, and how grid is generally balanced. But as with all engineering problems, devil is in the details. And details make his model utterly ridiculous and completely unfeasible. The problems here is DISTANCE and LOCALIZATION OF PRODUCTION.

    So you are arguing against widely distributed small generators on that basis? They provide LOCALIZATION OF PRODUCTION by their very nature, so I suggest you be a bit more honest about your reason for objecting to them.

    As nuclear is far more reliable

    It's a base load solution with a large capacity and is very expensive to turn off and on for peaks where you need a bit more capacity. Anybody who raves on about "one true energy" whether it is solar, wind, nuclear or coal is either selling something or has been conned - the answer is a mix of energy sources. It's cheaper to fire up a gas turbine (or several) than an entire coal or nuclear base load unit if you don't need the full capacity of a base load unit. Although wind has a lot of drawbacks it has a niche. Although photovoltaics are very expensive they now also have a place and are making a positive impact.
