Pan-European 'Supergrid' Could Cut 32% From Energy Costs (techxplore.com) 219

A European wide 'supergrid' could cut almost a third from energy costs according to a new study from the UCD Energy Institute. TechXplore reports: Evaluating the capabilities of Europe's energy network, the study, commissioned by SuperNode, found that a pan-European transmission system would reduce energy costs by 32 percent compared to the current approach. The 32 percent cost reduction identified is borne primarily from the expansion of European power flows -- derestricting them to allow the location of renewable generation to be optimized, thereby significantly decreasing the total installed capacity. While this scenario proposes an increase in transmission capacity, the costs were found to be insignificant compared to the cost savings in generation investment over the same period.

This study was an extension of work carried out by SuperNod, based on their Energy Scenario for Europe 2050 modeling -- which aims to predict future energy trends across the continent. Its modelling work, validated and extended by the UCD study and facilitated through ConsultUCD, demonstrates the net benefit of large investment into the development of new transmission assets to ensure more efficient utilization of Europe's renewable resources; highlighting bottlenecks where investment is required, such as higher levels of grid storage. [...] Another key finding from the UCD study is that the existing transmission system is not fit for purpose for Europe's energy future. Without accelerated investment in infrastructure, Europe will face challenges with load shedding, generation curtailment and excessively high emissions. The failure to achieve decarbonisation targets will not just undermine international climate efforts but will adversely affect Europe's economies and ability to compete on a global scale, the report notes.

    Here's the interesting thing: the implication of moving to renewables and Net Zero is that you have to redo the transmission system. Its not an option.

    The closer the Eiuropeans (including the UK) get to planning Net Zero, instead of just talking about it, the more social and infrastructure implications emerge.

    This one is about redoing the transmission network. The latest UK information is another one, its that the utility companies there are talking about implementing smart meters to measure power use every half hour, and implementing differential prices according to total demand. We have already heard that the plan is to put car chargers and heat pumps on smart meters, so they can be turned off as needed to protect the grid at peak demand times.

    All this is coming out because they are planning to, at the same time,

    (1) move electricity generation to wind and solar
    (2) move home heating to heat pumps and cars to EVs

    They have a grid which cannot be moved to wind and solar in its present state, if done it will not meet current demand, and without a huge expansion cannot handle the increased demand from the proposed move to heat pumps and EVs.

    It can't handle the current demand because of intermittency. Its not possible economically, or probably logistically either, to install enough storage. All the attempt would do is increase use of gas powered backup.

    You want to see this in action, look here: https://gridwatch.co.uk/WIND [gridwatch.co.uk]

    All this is best considered as the social or financial cost of moving to wind and solar, just becoming clear. What its going to mean is that the financial risk of peak demand surges, currently borne by the supplier via the spot market, is going to be transferred to customers. At the same time, their access to the power they need to charge cars or heat homes will be curtailed via the smart meters.

    The UK and the EU are going to be poorer, colder, darker and less mobile. And the effect on the global climate is going to be zero.

        Whether the costly implementation of a transmission network is reasonable depends on the costs and benefits. Saying that it's not a reasonable option would imply an even greater level of insanity to the transition from kerosene lamps to electric lighting and the required costly implementation of the original electric transmission network.

      The rest of Europe is aiming to move to 15-minute measurement periods.

      UK seems to be going for "load shedding by force" by your description.

      In the Nordics on the other hand we're starting to see peak power charges. That is, your standing charge is determined by your peak use the last year. This gives a real incentive to not run your 11kW car charger at the same time as your 9kW electric Sauna and 4kW of Oven with Christmas ham cooking, especially not if it's cold outside and your heatpump is eating 12kW just to keep the house warm.

      I'm manually setting my heatpump to produce warm water for shower during the cheapest hour of the day. I'm hoping in the future to have a raspberry pi fetching weather reports and price forecasts so it could bump up the house temperature a bit before it gets cold and power gets expensive, and then let temperature indoors slide down a little bit during the cold period.

      It's overall somewhat nontrivial to manage heating by heatpump. Let's say you let indoor temp drop down while you're at work. In order to raise the temperature again, the heatpump is going to have to work harder. When it does that it's less efficient. The efficiency loss might or might not negate the power saved when you were at work.

      Already now with just manual measures like running dishwasher and laundry at night with their built in timers, my average electricity rate would be lower than the average wholesale price of electricity.

      I helped write the smart metering standards for North America got stuck with the helping edit and resolve the piece of crap the UK came up with. I'm a huge fan of smart metering, the idea of matching demand to supply as opposed to the current system of supply to demand. If it is after 6pm solar isn't going to do you any good and wind can't be predicted weeks in advance.

      Here are three examples of how stupid the UK changes where. Some UK smart meters can turn off the power to the house if the bill isn't paid. They wanted a device where you could "pop down" to the corner shop and get a code that would top up your meter. Of coarse you need a device in your house to enter this code in and I proposed a secure way to create the codes and relay them to the meter. 6 months later I see the UK had mostly adopted my ideas but added extra security to it. This extra security required the entry device to always be in communication with the meter, which meant it had to be plugged in, plugged in in the house where the power is off. The entire conference room laughed when I pointed it out but after the meeting I was actually physically threatened for pointing this out. Some companies said something along the lines of don't rock the boat, if we have a standard to build to the UK government will buy them regardless of whether or not they work. What they said is true, the Scottish utility once got a subsidy to buy devices to monitor home electric consumption. They chose a device that mostly didn't work but it didn't matter, the subsidy was for buying the devices not deploying them.

      Screw up number two, inside the smart meters there are is the actual metering device and a separate communication module. The UK government decided that the coms and meter should be made by different companies but couldn't agree on a connector between the parts. As a result they talk wirelessly inside the meter.

      Three, the certificates used in the UK are based on EC-QV implicit certificates. These are small, easy to validate and don't have the redundant length parsing vulnerability inherent to ASN1 based certs (e.g.X509). But no one in the UK understood how they worked and they swapped the order of the fields creating a requirement that the hash used be collision resistant. The hash used in the UK and North America is 128 bit AES-MMO. The North American implicit certs though only require 2nd preimage resistance. GHCQ claimed for months my math was wrong but I was eventually able to devise a simple proof of the flaw. Instead of changing the certificates they came back with it "has already been agree, you can't change it". I was on the committee, I sure as heck hadn't agreed to it, little did I know my job was just to help the editor and give the stamp of approval that it was an open standard. They did add an extra field near the start of the certs that would, if unknown to the attacker, prevent them from creating hash collisions but, I found out 5 years later, the entity creating this field was never told the field was for security and are not setting it in an unpredictable way.

      There is arrogance, stupidity and corruption in every committee, but the UK has cronyism and they do stupidity with a level of impunity that I've never seen in any other western country.

        Unfortunately you ran straight into a part of UK corporate face saving culture there too. To avoid them and their company being "embarrassed" a nasty root of corporate stubbornness has taken hold where certain people will DO ANYTHING to ensure what is presented does not disagree with what they just said. Basically the trick to get around it is to privately agree changes in little informal meetings before the formal meeting, as what is presented there will be fait accompli. The formal meetings are just as much fluff these days.

        Yep, the UK switch to smart meters has been a complete disaster. Aside from the spec being rubbish, which you kindly documented in your comment, the whole thing was a mess on the consumer side too.

        First they installed SMETS1 meters, which usually only worked with the energy provider that installed them. The next standard, SMETS2, could work with any provider if they could figure out how to get the data. So all the old SMETS1 smart meters need to be ripped out and replaced eventually.

        Pre-paid meters have been a problem in the UK for decades, and smart meters didn't improve things at all.

      • The UK government decided that the coms and meter should be made by different companies but couldn't agree on a connector between the parts.

        That is surprising. The IEC 62056-21 protocol already exists and it is usually used either with a RS485 connector or through infrared.

      The UK already has a wholesale electricity market that varies cost based on supply, not demand, it's been running successfully for years.

      The intention with Smart Meters and flexible tariffs is to reflect that wholesale cost to customers which then results in their usage better reflecting the available supply. Multiplied across millions of homes that will dramatically change demand and potentially avoid peaks in the first place, or reduce them to the point that storage can balance it. You can do it with smart devices today, EV chargers, battery smart inverters and similar. We already have tariffs that reduce during off-peak times and may even go negative at points so consumers are being paid to use electricity, smart devices poll the provider and flex usage based on that.

      If you have inflexible need for electricity then it's not going to be turned off, that is nonsense, it'll just cost more. If you have a car that sits for 12 hours but takes 4 to charge then why would you care if it's smart charger moves the charging time around? If you have a well insulated house then why would you care if the heating stops working for any given 30 minute period and the temperature drops by 0.2 degrees. We're not at that point today with the UK housing stock or vehicle fleet, but this is a long term approach.

      Storage is not the solution for intermittency, it's for local balancing. Running the entire grid from stores while the wind drops is not feasible. The current approach is a mixture of HVDC interconnectors, flexible usage, nuclear baseload, diverse generation sources and financial drivers to reduce the time that carbon creating generation methods are being used.

      Yes there will be a cost to this, the current belief is that the cost of doing nothing will be far higher. If you don't believe that then no doubt the investment won't seem worthwhile.

      No, it means you just need more capacity overall. Each site will be sized according to availability of energy and land ownership rights.

      Most likely much of the capacity will come from the North Sea and other off-shore wind farms.

      You would not have thought that the consequences of moving to Net Zero to save the planet would include tracking every single mile everyone drives, making it impossible to charge your car or heat your home between 5 and 8pm, and exposing you to the fluctuations of the spot electricity market for the power you need to cook dinner or take a shower or make a cup of tea.

      Fortunately none of that will happen.

      For per-mile taxing they will simply use the odometer reading at the yearly test every vehicle must go through to ensure it is safe and meets emissions standards. In the UK it's called an MOT, and it's mandatory. No need to track where the vehicle is the rest of the time.

      You will be able to charge your car or heat your home during peak times, it will just cost you more. Fortunately we have already figured out how to use timers to delay charging and heating to cheap times, and insulation retains the heat over the expensive parts.

    Fortunately this study is from an independent agency, without any financial stake in the game. Just kidding:

    SuperNode, headquartered at NovaUCD, designs and delivers superconducting bulk power transmission products to enable the future growth in large-scale renewables to help create a decarbonised energy supply.

    Do they really claim they can ship systems of superconducting transmission lines whose costs will be "negligible"?

    • I was wondering a bit why you needed a study, when you could have the current electricity markets rerun a year worth of auctions algorithm except have them set interconnect capacity to infinite.

    derestricting them to allow the location of renewable generation to be optimized, thereby significantly decreasing the total installed capacity

    Does this journalist know English? After reading that about three times, I can figure out what he meant, but what a tortured sentence.

    In a nutshell: If one installs more transmission capacity, the need to build *new* capacity will be reduced. Which isn't saying much, because demand is going through the roof. Where I live, more than 50% of new cars sold are EVs. Heating systems in new builds are heat pumps instead of oil. And some countries (Germany, for example) are turning off their nuclear plants.

    Renewable energy still doesn't make the cut. There are times - maybe once or twice a Winter- where almost all of Europe simultaneously has bad weather. A massive cold front with cloud cover and snow (or rain, in the south). Solar power = zero. During storms, wind power is also often unavailable, because wind speeds are too high. Where is that power - in the middle of Winter - going to come from? Magic fairy dust?

    • Renewable energy still doesn't make the cut. There are times - maybe once or twice a Winter- where almost all of Europe simultaneously has bad weather..

      It happened last year, from July through to October, wind speeds throughout much of Western Europe were the lowest since the 1960s with the UK's wind output barely averaging 2GW out of an installed capacity of 25GW. Solar output was also below average. Good luck finding a storage solution that will cover that.

      Wind and solar has its place as complementary sources but it's pure fantasy to believe you can power Northen European nations solely from something so intermittent and unreliable.

      • Natural gas supplies from Russia are intermittent and unreliable. It's cheaper to produce electricity using a solar/wind installation with gas peaking backup than combined-cycle gas. Those economics just aren't going to change since the price of the wind and sun don't vary.

      Because some forms of renewable energy are intermittent and some are less predictable than others, you need to over-build capacity. You over-build to the point where you can guarantee you have enough energy all the time.

      If you have a very highly connected grid that can move large amount of energy around, you don't need to over-build so much. The more widely distributed the generation is, the less it is subject to local variations in energy availability.

        That is a fair point only if you do not care about price. Otherwise you need a huge amount of storage (expensive as well but possibly less) or fossil fuels (a cheaper option).

        • by AmiMoJo ( 196126 )

          The cost can be kept low if we develop industries that can take advantage of excess cheap energy when it becomes available. Producing synthetic fuels, desalination, hydrogen production, opportunistic computing (there was an article about it yesterday on /.)...

          • by vyvepe ( 809573 )
            I can agree on the synthetic fuel production. It may work if we can find a cheap enough process to make them. They are enough energy dense to make a sense. The rest is unlikely to be good for absorbing intermittent overproduction. Too little energy density or too much capital tied in only intermittently used processes. The problem is that we need to store a LOT of energy for zero emission energy industry to be feasible.

          There is enough wind energy in the North Sea to cover all year round, every year. It's just a question of if we want to harvest it all.

          The other alternative is to keep some fossil fuel plants around to cover those times. Their emissions can be captured and sequestered, and offset in other ways. Net zero doesn't mean zero emissions, it means that any emissions that are made are offset by some means.

          • There is enough wind energy in the North Sea to cover all year round, every year. It's just a question of if we want to harvest it all.

            Sure, because the zone of bad weather that covers Europe is mathematically guaranteed to always have a hole for North Sea.

          In case you mean: bad for energy production, then we have to correct you. Winter is best time for wind.
          And in case we get the nice Russian high pressure zone, it is superb for solar too.

      Part of the answer to that is: another European country. If, say, Germany is suffering from the February high pressure zone above Scandinavia, Ireland and southern European countries are not. There must be a cold front somewhere with a lot of wind, and the high pressure zone is usually sunny. That is why a multinational supergrid makes a lot of sense.

    The latest French government has settled on nuclear power for baseline needs, seems like the best choice when the rest of the neighbors are committing to russian gas as the fuel to provide for the peak and home heating needs. The Germans seeing the French are setting themselves up as the EU power source will thaw on new nuclear plants as the grid becomes viable for massive energy exports. The southern EU nations with open spaces will counter with Solar. I expect electricity prices to go down over the next 40 years as time shifting of load by storage and control methods take hold for real. Taxes per KVAHr will sometimes be the only cost to power loads that can be delayed to weekend nights.

    North Africa will be covered in solar panels and a hydrogen or synthetic hydrocarbon (from carbon dioxide capture) will flood the world with cheap transport fuels of all types.
    With sufficient baseline covered at least the northern EU wont freeze if that gas supply ends up not cheap and reliable. The industry of EU can be stopped by an external player, must feel good to be in that place.

    Solar roofs will just about offset the needs of the consumer EV market for all but the most high rise of regions. The public EVs such as buses and trains already are accounted for as baselines.

    The rest of the EU industries collectively are becoming more energy efficient per unit of GDP as to make Global warming commitments carbon heavy industries are being exported at a rate now matching NA exceptional rate. The rich are putting the dirty into 3rd world nations, what else is new.
