Sweden Rejects a New Electrical Interconnection With Germany (enerdata.net) 103

sonlas writes: Germany's energy transition plan includes extensive interconnection projects to distribute its intermittent renewable energy production. However, these projects face significant challenges. The latest example is Sweden. One such project, Hansa PowerBridge, announced in 2017, intended to link Germany and Sweden via a 300 km HVDC line through the Baltic Sea. This 700 MW project, estimated at 600 million euro, aimed to stabilize Germany's volatile electricity prices. However, on June 14, 2024, Sweden rejected the project, citing incompatibility between the countries' electricity systems. The connection would link northern Germany to southern Sweden, an area with insufficient infrastructure. Concerns also arose about the volatile German market disrupting Sweden's and increasing local prices. Energy Minister Ebba Busch justified this decision by saying the German market is currently not efficient enough and a connection would risk leading to higher prices and a more unstable electricity market in southern Sweden.

This highlights the difficulty Germany faces with its Energiewende, or energy transition model. This model leads to erratic electricity price behaviors and significant challenges in balancing production capacities. While a possible solution for Germany lies in interconnection with neighboring countries, the examples of Norway (which cancelled the NorGer project too) and Sweden show that from the perspective of these neighbors, it looks more like an "export of German problems" rather than a solution.

          Renewables are a bit like coal - both solutions externalise their costs and dump them on others. In case of coal it is pollution and for renewables it is grid instability. Let’s say renewables manage to price out nuclear and force it to shut down. Great, right until next night without wind.

            Indeed. The problems are to a quite great extent solvable with renewables, for a price. The lack of cold starting can be addressed with grid forming inverters. The lack of inertia and short term stability can be solved with synchronous condensers. And the weather problem can be solved with a mix of storage, massively increased long distance grid capacity and responsive loads.

            All solvable, none of it for free. I wouldn't quite say it's externalized because as the fraction rises the attendant price will start to bite. The grid operators will start paying for stabilization services, which may include thermal power plants, and the prices will go on the bill ultimately.

            Also WTF is with all the ragging on France. Since the 1970s France has dumped vastly less CO2 into the atmosphere and killed and maimed vastly fewer people from pollution from electricity generation than all of its peers. Sure it was "expensive", but that's because everyone else externalized the costs.

            The people promoting the environmental choice bloody well ought to know this. From an environmenal perspective, France's record here is way better than the one of whichever high horse they're riding.

          Or maybe Germany could fix its insane policy instead of chanting "there is no alternative" and then frantically looking to dump grid instability it causes on neighbours? When Germans looked at their coal plants and nuclear plants, then decided to kill the clean ones, they lost any right to lecture anybody else about 'saving humanity'. I could even understand the original Shroeder's plan that was stretched out to 2040 (if I remember correctly). It would possibly give enough time for storage to get so cheap, that coal could be killed immediately and then nuclear could be seamlessly phased out in favour of PV/wind+storage.

          However what Merkel did later was criminal.
      • According to the law the conservative Merkel government wrote, they can't.
    • This isn't sharing, it's Germany asking for expanding their market. If you have goods in one area that are cheaper and a more expensive area if you start to exchange goods then the prices start to move toward each other. Which is great for Germany, but no one wants higher electrical prices, especially in Sweden and Norway. So no connection.
      • I can kinda understand it. The electricity prices here in Norway skyrocketed after we installed new cables and joined the European ACER treaty. Mean yearly prices are up from about 0.3 NOK in 2017 to 1.4 NOK (with peaks up to 7 NOK) in 2023. That's a lot considering most Norwegian households typically use electricity for heating.

          Trade usually benefits both sides. Norwegian electricity companies must then make a lot of profit, which should overall benefit the economy in Norway. If the higher prices hit Norwegian households too much, this could certainly be fixed in different ways, e.g. with tax breaks, which should still be cheaper than not having the interconnection.

When the wind doesn't blow, Germany wants Swedish electricity and who knows if Sweden's capacity can provide it. These renewable projects need to be balanced locally.

      It's far worse. Germany periodically experiences periods of Dunkelflaute in winter: no wind, no sun (due to the short day and clouds), and low temperatures. These periods can last for _weeks_, and about once a century for a _month_ straight.

      No amount of batteries can supply that much buffer capacity. Right now coal and gas are used to ride out these cold spells.

          Also dams already built were usually built to have a surplus of water most of the time so they dump water downstream on a regular basis and/or just let it constantly overflow. Thus, having more water in the tank wouldn't be that much profitable most of the time.

          • In many cases, plain old hydroelectric power does as well as pumped storage. Think of the cyclical nature of pumped storage (water goes down, water is pumped up) offset by normal steam flow such that the peak in the storage part of the cycle is just zero. That's where a plain old hydro plant just lets the reservoir fill.

            It's just a matter of sizing the reservoir and generation correctly.

          • Maybe new dams should be built with that in mind, big them bigger than the natural water flow would justify and have them double as pumped energy storage for renewables. Some existing dams could possibly be retro-fitted for that purpose as well by augmenting capacity

            This may work in some places. I live in Manitoba, Canada, and most of our electricity is generated by hydro dams in the north. We have a large lake - Lake Winnipeg - which acts as a reservoir. The utilities operating license requires them to keep the lake within a certain height, because people actually live there. This limits how much water can be stored at any given time.

          "Lots of energy" is overstating it. Your typical battery stores enough energy to have full output for 2h and typical pumped storage is anything between 4h and 24h (usually closer to 4h). So it's not even close to providing enough energy to last for a week.

      Whever someone talks about "Germany" when speaking of an electrical grid problem you can see they don't have much of a clue. "Germany" doesn't get too much electricity. The northern tip of Germany gets too much electricity. They were looking for links to Sweeden and Norway to export wind in an effort to avoid building thousands of km of transmission lines between the north and south.

      In this regard Germany is as much a cohesive grid as the USA is a cohesive grid. There are different areas with different challenges and much like Texas, there are areas that don't currently play well with the rest of the country. Renewables don't need to be balanced locally, they need to be balanced over a large area. Hence efforts to upgrade grids and interconnect them.

      As for storage, firstly grid scale batteries acting as capacitors definitely exist, quite a few of them are in deployment, the first popped up in south Australia. For larger storage there are alternate technologies which also exist, e.g. Ammonia based storage systems (which has plants currently under construction, with a 55% end to end efficiency, and the ability to simply use big tanks to increase capacity (I say simply, this shit is toxic so it's an engineering challenge). Load balancing is also part of the solution. E.g. the very north of Germany currently has a large electrolysis plant being put up to stabilise the electricity grid generating green hydrogen when electricity is abundant, and dropping back to SMR when it's not, and then feeding a local refinery in effect using the intermittency to reduce the carbon footprint of a fixed consumption carbon emitter.

      By the way I've never met a solar or wind proponent who doesn't also recognise energy storage as being a required part of a stable grid. However...

      Right now, until grid scale batteries exist, nuclear is the only option.

      Option for what? Germany needs a solution now and in the next 10 years, not something that may be commissioned in 20+ years. Nuclear has zero position to play in any current electrical grid problems or any current climate goals. It's the time to construction that the the nuclear fanatics refuse to see and won't admit to.

Particularly when the system operator calls and tells you to go on line on a windless day. The power biz has had these issues solved for more than a hundred years. But now, some people want their own set of rules. Nope.

      • The 100% renewable energy storage problem is quite vast though, and the scale of the challenges involved are often downplayed quite strongly.

        I've noted many of the numbers quoted for the energy storage required assume 2-3 days, or maybe a week. You can definitely assume some renewable capacity will still be online during a reduction in generation (maybe a large bushfire reduces your solar output significantly), so you don't need enough storage to cover all power consumption... but you still need a lot.

      Why would Sweden buy the electricity if they don't need it?

      What you mean is that at times the price of electricity in Germany is extremely low, and Swedish energy producers are worried that it will undercut them. Meanwhile they don't see the opportunity to sell electricity to Germany as profitable enough, because as Germany's (and the continent's) grid gets greener the average price will keep falling.

        Yeah. That's exactly the opposite, but keep telling you that.

        Germany wants and needs this interconnection. Sweden does not want it and does not need it. There isn't much else.

          TFA actually explains it:

          Germany is a single power market zone, with a unified wholesale price. However, congestion on its grid, which lacks connections to move power from the wind-rich north to consumption centres in the south, has increased calls for a split into at least two zones.

          Germany opposes such a move, which it fears could increase prices in the south and impact industrial activity.
          By comparison, Sweden is divided into four power price zones.

          "The German power market doesn't function in a way that gives correct price signals to power market players, mainly because Germany, unlike Sweden, isn't divided into electricity areas in a way that corresponds to the significant bottlenecks," the Swedish government said.

          It's exactly what I said. In Sweden they like to have price discrimination based on location, because it is more profitable. A divided market is easier to exploit. The more freedom people have to buy energy from the cheapest source, the worse it is for them.

          • Germany is a single power market zone for the wholesale prices only. End users are discriminated based on location (sometimes the prices differ even between city districts) and have a lot of freedom to buy energy from hundreds of different sources.

          • Nope. Sweden simply doesn't want to be the one solving Germany's problems (grid instability and intermittency), because it would cost them money to solve those problems. Germany should and will be the ones paying and assuming their choices.

            Sweden solved those problems by having a good electricity mix [nowtricity.com]: 42% hydro, 22% wind, 30% nuclear (in 2023). They don't need Germany's "cheap" electricity, especially when it is at time where they already have enough electricity themselves. Germany, on the other hand, is fr

      • The free market doesn't solve all problems. One in particular it doesn't solve well is stability and consistency. All countries regulate their grids heavily to promote stability and consistency and Germany is no exception.

        There's a lack of interconnections in the German grid. Sweden doesn't want to have its energy producers pushed into unprofitability and therefore close, so Germany doesn't need to build those interconnections. Because then Sweden will be on the hook for their own ones.

  • This smells like protectionism, but perhaps it is justified. Germany has loads of excess electricity at times and is looking to export it, probably at very cheap prices. That could undercut national power sources in Sweden and stress their viability.

    • Yes, that is also the experience in Australia. The existing generators in Australia cannot be run economically at 3 c /kW, and so are taken offline when the wind blows and the sun shines. The lower profitability deters maintenance-why bother maintaining an asset that government policy wants closed in 1-10 years? The lie is then told that FF plants are unreliable - no they were fine until they had to go intermittent.

      But of course when the wind doesn't blow and the sun doesnt shine, as happens for 10 hours 3

    • his smells like protectionism, but perhaps it is justified. Germany has loads of excess electricity at times and is looking to export it, probably at very cheap prices.

      They also have massive shortages at times and import lots of electricity to cover it, raising prices in the neighboring countries. Which is cool for the energy industry, not so much for local users.

      • >> raising prices in the neighboring countries

        Show evidence. Germany is a net exporter of electricity.

        "The trade figures show that Germany's neighbours remain dependent on surplus power from Europe's biggest economy if their own generation supplies fall short."

        "Due to the technical problems affecting French reactors, Germany for the first time sold more power to France than it received from its neighbour, doubling its year-earlier export volume there."

        • Note that your link talks just about 2022, where France had problems due to technical problems, and it was an exception that they sold more to France than they bought. Which makes your claim "Germany is a net exporter of electricity." a bit shaky. It was in 2022, and your link supports the claim that it wasn't before. Since it's an article from early 23, there's no info after. But I'd venture to claim that it is upon you to show evidence that the tables have turned.
          • >> it is upon you to show evidence that the tables have turned

            The internet is easily searchable. If you have evidence contrary to what I showed its up to you.

            Here's more recent info. Figure 1 shows that Germany exports more than it imports.

      It is only protectionism” in the same way as forbidding your neighbour from dumping their trash into your backyard. Germany made a mess of their energy system by their insane policies (but the voters said so” does not trump physics it turns out) and now they are frantically looking for some sucker to pay for it.
      • >> Germany made a mess

        Germany has excess electricity at times. That doesn't make their energy system a mess and Sweden doesn't say it is.

        Sweden vaguely claims that "The German power market doesn't function in a way that gives correct price signals to power market players", and most likely that simply means the Swedish companies wouldn't be able to compete on price.

  • Sure sure, the EU, it's a like a "Union" of "Europiean countries" except not.

    Electricity is easy. Maintaining a close ratio of generation to use is not, and that's why we have power grids (no, Texas, ERCOT is not one).

    AC? Sure. DC? Sure? Long distance high voltage low current transmission lines? Sure. AC kinda sucks because of needs for substations and capacitors and transformers. DC kinda sucks because a power line on the road REALLY WIL KILL YOU.

    Sweden (love them folks) took 7 years to tell Germa

    • AC kinda sucks because of needs for substations and capacitors and transformers. DC kinda sucks because a power line on the road REALLY WIL KILL YOU.

      I'd argue the substations and transformers are way way more expensive for DC than AC. The main advantage of AC is the substations are cheap (relatively), robust and bidirectional. The advantage of DC is for high powers at long distances.

  • Seems like every other week I see a story about one or more undersea network cables getting cut by "accident", but I never see anything about undersea power cables. Are these cables better protected? Are they less newsworthy?

  • for shutting down their nuclear baseload. Germans love coal.
  • The conservative minority government of Sweden that is hellbent on going nuclear decided this a few days after their member parties lost votes to the Greens in the EU election. Odd.
