If you continue just to build more renewables without tackling the grid, of course you spend a lot of money and then you have to curtail the renewable generation at a certain point of time because you have too much, the grid cannot take it and cannot deliver it to the consumer.
00:00:16.088 --> 00:00:19.789
So, of course then you have no economical benefit of doing so.
00:00:30.268 --> 00:00:35.279
And once the grid becomes a constraint, this stops being just an energy problem.
00:00:35.819 --> 00:00:41.219
It starts shaping where investment, industry, and electrification can actually happen.
00:00:42.329 --> 00:00:46.079
Good morning, good afternoon, or good evening, wherever you are in the world.
00:00:46.499 --> 00:00:55.768
This is Climate Confident Stories and Strategies that Cut Emissions episode 294, and I'm your host, Tom Raftery.
00:00:56.759 --> 00:01:11.069
My guest today is Niklas Persson, CEO of Grid Integration at Hitachi Energy, and we're going to look at the grid as the missing link between clean generation and real world decarbonisation.
00:01:11.459 --> 00:01:22.920
From interconnectors and resilience, to permitting, industrial competitiveness, and the infrastructure needed to make electrification work at scale.
00:01:24.000 --> 00:01:24.689
Let's get into it.
00:01:25.588 --> 00:01:26.159
Niklas.
00:01:26.179 --> 00:01:27.528
Welcome to the podcast.
00:01:27.528 --> 00:01:29.088
Would you like to introduce yourself?
00:01:29.772 --> 00:01:30.552
Thank you Tom.
00:01:30.552 --> 00:01:32.591
Really happy to be with you today.
00:01:32.591 --> 00:01:39.484
So Niklas Persson is my name, working with Hitachi Energy since almost 30 years now in the industry of electrification.
00:01:40.215 --> 00:01:56.697
And today I'm the CEO of GRID integration that is covering all our systems solutions within Hitachi energy, working with HVDC, power Electronic Solutions, substations and other grid solutions that the society badly needs today, Tom and happy to be here with you.
00:01:57.500 --> 00:01:58.159
Fantastic.
00:01:58.159 --> 00:01:59.629
And for people who are unaware.
00:01:59.640 --> 00:02:09.379
Niklas, can you give us some kind of top line numbers around Hitachi Energy, you know, number of employees gigawatts under control, countries worked in, anything like that?
00:02:10.899 --> 00:02:14.588
We are a company that is working in more than a hundred countries.
00:02:14.748 --> 00:02:18.139
You can say Asia, Europe, Middle East, and Americas.
00:02:19.128 --> 00:02:21.769
So quite well spread from a geographical standpoint.
00:02:22.519 --> 00:02:27.699
And today we are more than 50,000 people and have more than $20 billion of revenues.
00:02:28.299 --> 00:02:30.068
And we are rapidly increasing.
00:02:30.068 --> 00:02:34.436
So we, we grow with the, ambition that the society have today.
00:02:34.538 --> 00:02:42.248
So we are a the world number one in electrification when it comes to transmission systems and transmission products.
00:02:42.794 --> 00:02:46.663
We are very happy to be in that spot and to be able to support our customers.
00:02:47.572 --> 00:02:48.201
Fantastic.
00:02:48.201 --> 00:02:55.431
And what does then grid integration actually mean and why should someone running a business care?
00:02:56.485 --> 00:03:08.277
We are putting everything together and engineering solutions in a even more complex system today that we have with more renewable integration coming into the energy system.
00:03:08.997 --> 00:03:19.127
And that's where we provide value to our customers to run large projects, do the engineering, the delivery, and the construction of these large projects.
00:03:19.795 --> 00:03:28.586
And Niklas, for decades, if not longer, the grid has been largely invisible to people, but that's changing very quickly.
00:03:28.586 --> 00:03:34.165
So what would you say has changed to make grids now a policy and boardroom issue?
00:03:35.304 --> 00:03:47.264
I think in the past we have had a, a very successful target both from customer but also from Hitachi Energy and our competitors to improve efficiency.
00:03:47.954 --> 00:04:02.963
And while electricity as a share of the energy mix has not rapidly increased, we have been able also to utilise the spare capacity you can say in grids, but also come with more efficient solutions with less losses.
00:04:02.963 --> 00:04:08.633
So you can run the grid more effectively in the past and now for various reasons.
00:04:08.633 --> 00:04:16.223
But of course the change in the energy mix that we want to add more renewables into the grid is changing.
00:04:16.553 --> 00:04:35.517
We also want to have a more secure and, and resilient grid, which means that we have to have more electricity instead of fossil fuels, especially in the regions like Europe, which wants to be less dependent on fossil fuel in the future, which means that you need to have grid to carry the electrons to the consumers.
00:04:36.478 --> 00:04:43.240
And this is of course then spiking the electricity demand industries and data centres, et cetera.
00:04:44.747 --> 00:04:48.240
Also want to have more electricity or clean energy.
00:04:49.021 --> 00:05:02.110
And therefore you see now today a much bigger interest of grids because that's the key bottleneck, to make sure that you do this energy transition, not only to change the type of generation that we have, today.
00:05:03.285 --> 00:05:03.735
Okay.
00:05:04.665 --> 00:05:11.774
Are we reaching a point where building more renewables without fixing the grid delivers diminishing climate returns?
00:05:13.218 --> 00:05:29.608
I would say if you continue just to build more renewables without tackling the grid, of course you spend a lot of money and then you have to curtail the renewable generation at a certain point of time because you have too much, the grid cannot take it and cannot deliver it to the consumer.
00:05:30.209 --> 00:05:33.908
So, of course then you have no

economical benefit of doing so.
00:05:33.999 --> 00:05:49.809
So you have to have a synchronised planning to be able to achieve what we want to achieve actually to change fundamentally the energy system, to carry more electrons than to have an energy system that is based on fossil fuels.
00:05:50.749 --> 00:05:54.769
When the grid can't keep pace, where does that pain show up first?
00:05:54.769 --> 00:05:55.699
Is it emissions?
00:05:55.699 --> 00:05:56.629
Is it prices?
00:05:56.629 --> 00:05:58.098
Is it reliability?
00:05:58.098 --> 00:05:59.119
Investments?
00:05:59.209 --> 00:05:59.629
Somewhere else?
00:06:00.550 --> 00:06:02.939
Tom, I think it's all of the above actually.
00:06:04.199 --> 00:06:14.579
You have pain points everywhere, but I think the, the one that is seen now in many countries that you have, 10's of gigawatts of applications where they want to connect to the grid.
00:06:15.660 --> 00:06:32.149
This is of course a big pain point where, could be a data centre, it can be an industry, it can be a, a fleet of vehicles that wants to connect to the grid and get energy through electrons that is simply not onset positively within time.
00:06:32.759 --> 00:06:38.569
So you have the risk of having, of course, a more renewable energy or any energy source.
00:06:38.629 --> 00:06:45.180
Could be nuclear as well added grid, but not grid that is ready to receive it in an effective way.
00:06:45.180 --> 00:06:47.370
And of course, that is the key challenge.
00:06:47.370 --> 00:06:49.966
We as a society, especially here in Europe have.
00:06:50.430 --> 00:06:56.939
So would you say grids are becoming an industrial competitiveness issue as much as an energy issue?
00:06:57.759 --> 00:06:58.600
Absolutely.
00:06:58.644 --> 00:06:59.829
I, I, I believe so.
00:06:59.829 --> 00:07:05.170
I mean, if fundamentally, if you take Australia, it's a very interesting case actually.
00:07:05.800 --> 00:07:17.627
And they are managing to add a lot of solar, but also wind into the energy system to be cleaner, but also to have homegrown energy to be resilient in terms of the energy source.
00:07:17.699 --> 00:07:20.040
And they're managing the complexity that comes with it.
00:07:20.129 --> 00:07:28.350
We have also, to be clear, renewable integration is going to have less intermittency in the grid and that has to be managed.
00:07:28.769 --> 00:07:37.029
Thereby they're adding a lot of battery energy storage so they can manage the fluctuation and still run a grid that is reliable.
00:07:37.509 --> 00:07:42.250
And Australia is managing this and they are moving very fast, I must say.
00:07:43.149 --> 00:07:50.019
Of course, it's very expensive in the transition when you still have the old way of doing things and you're adding the new way.
00:07:50.019 --> 00:07:59.089
And that transition, and this is where we as a consumer, we see some pain points on industries that in the transition period it'll be a bit expensive.
00:08:00.110 --> 00:08:06.259
That means
there's kind of an awkward investment problem then that the grid has to arrive before the demand does.
00:08:06.259 --> 00:08:13.574
So what's more expensive, building grid capacity too early or waiting until demand is certain?
00:08:15.024 --> 00:08:20.543
I think one way of actually managing this Tom is also to look at interconnectors.
00:08:20.543 --> 00:08:23.918
I think we have to collaborate more.
00:08:24.648 --> 00:08:40.288
And you see this in North America, you see it in Europe, but you see also quite interesting phenomena in India and in China, which are vast regions or countries where they shift bulk power across states.
00:08:40.557 --> 00:08:42.697
It is one country and they can manage it.
00:08:43.268 --> 00:08:48.999
While here in Europe, but also partly in North America through state regulations and federal regulations.
00:08:50.148 --> 00:08:56.038
We are not as interconnected as these large continents are or will be in the future.
00:08:56.187 --> 00:08:57.868
If you look into India and China.
00:08:58.967 --> 00:09:10.293
And I think that that's somewhere where we can actually ease the cost of generational grid first to do more interconnected, because that adds flexibility to the grid.
00:09:10.474 --> 00:09:19.974
And this is an area where I, I believe our politicians and the grid planners and and so on that they need to really look into, add more interconnection capacity.
00:09:20.615 --> 00:09:22.924
Nicholas's answer points to a third option.
00:09:23.764 --> 00:09:27.365
Don't treat every national grid as an island.
00:09:28.115 --> 00:09:33.394
Interconnection can reduce the amount of spare capacity each system has to build alone.
00:09:33.845 --> 00:09:39.039
But does that shared dependence make you safer or more vulnerable?
00:09:40.118 --> 00:09:43.707
Here it becomes, from my perspective, it's a political discussion.
00:09:43.707 --> 00:09:55.398
And of course you can see that relying on Russian gas, which is another type of energy through a gas pipeline instead of a cable or an overhead line, that made you vulnerable.
00:09:56.227 --> 00:10:04.508
At the end it is about peace and, and countries that have the same kind of view on the, on the world, the order, et cetera.
00:10:04.807 --> 00:10:14.695
If you can collaborate cross borders, of course that is the most efficient way of building out the grid and the energy system.
00:10:15.508 --> 00:10:24.477
And I believe that that is the also a way of getting countries to actually align and, and work together because it's cheaper at the for both parties.
00:10:25.126 --> 00:10:33.197
So is energy independence in an electrified world actually going to require more interdependence?
00:10:34.541 --> 00:10:41.321
I don't think you should say yes if you want to be a country where you say, okay, I take care of myself and so on.
00:10:41.681 --> 00:10:43.931
But just think about the cost to consumer.
00:10:43.931 --> 00:10:53.291
If you have to design one system in one region to be fully self sufficient when it comes to own energy, you have to design your system for peak demand.
00:10:54.490 --> 00:10:55.390
Your own peak demand.
00:10:56.171 --> 00:11:06.600
And as a energy and electricity will grow in the future given the, trends with data centres, electrification of vehicles and industries, et cetera.
00:11:07.650 --> 00:11:11.581
If you then try to do that as a country yourself, it'll be costly.
00:11:11.610 --> 00:11:22.291
But if you interconnect and start to manage the system with the technology that is available today, you can reduce the cost to consumers and quite a lot actually.
00:11:22.801 --> 00:11:23.490
Sure, sure, sure.
00:11:23.490 --> 00:11:34.620
And we'll come on to Elmed in a second, but where have interconnectors already made a measurable difference to resilience, prices or renewable utilisation?
00:11:34.921 --> 00:11:39.043
I think for me, Denmark is a very good example actually.
00:11:39.403 --> 00:11:49.923
And from time to time they have more renewable energy than they consume and they have interconnectors to Norway, to Sweden, to Germany, to UK.
00:11:50.482 --> 00:11:55.123
And they can transport that wind energy to all these countries which is using it.
00:11:55.123 --> 00:12:04.035
And in Norway you can use it to not consume your hydropower water that you have in your dams and therefore you can save it.
00:12:04.035 --> 00:12:07.186
It's kind of a large battery, but it's water instead of batteries.
00:12:08.296 --> 00:12:20.885
So Denmark I think is a very good example of being, well interconnected, can sell energy at times, but there are also times when wind is not blowing and they have a deficiency.
00:12:21.816 --> 00:12:28.740
And therefore, Sweden, Norway, Germany, UK, can support Denmark in times of no wind or little wind in the country.
00:12:28.880 --> 00:12:35.485
And it is a super good example of how interconnection can actually help not only Denmark, but the neighbouring countries as well.
00:12:36.004 --> 00:12:37.684
I mentioned Elmed earlier.
00:12:37.684 --> 00:12:45.394
For people who are not familiar, can you tell us what Elmed is and then we'll dive a little deeper into that.
00:12:45.794 --> 00:12:49.695
Yeah, Elmed is an interconnector between Tunisia and Italy.
00:12:49.695 --> 00:12:54.914
So it's the first HVDC connection between Africa and Europe.
00:12:56.004 --> 00:13:18.320
And it's a great example of where you connect solar power, wind power where Tunisia is aiming to build out their renewable energy and creating a secure energy system in both ways, both for South Italy with Sicily and, but also for Tunisia when they would have deficiency or problems and so on.
00:13:18.504 --> 00:13:29.274
So it's both resiliency for both countries, but it's also in the future being an enabler for energy through electrons, but also in a more sustainable way.
00:13:29.835 --> 00:13:31.820
And what kind of size is the Elmed project?
00:13:32.629 --> 00:13:33.652
It's a 600
megawatt.
00:13:34.894 --> 00:13:35.735
600 megawatt.
00:13:35.735 --> 00:13:36.065
Okay.
00:13:36.455 --> 00:13:42.544
What becomes possible when we start connecting energy systems across continents rather than simply across neighbouring countries.
00:13:44.264 --> 00:13:46.004
So it depends how you run the system.
00:13:46.033 --> 00:13:48.313
But, but of course you can have energy trade.
00:13:48.714 --> 00:13:54.833
You can also sell and buy depending on your needs, but it can also be a generator.
00:13:54.833 --> 00:14:02.557
So if you add a lot of solar in southern part of Italy and you would run the, Elmed, project, let's say not at full power all the time.
00:14:02.557 --> 00:14:12.787
Let's say you run 400 megawatt and you, you would have a problem in the system, you can maybe very fast add another 200 megawatt, which provide inertia to the grid.
00:14:13.386 --> 00:14:32.652
So interconnectors, depending on how they are utilised and how you plan them, you can also use, use as kind of a generator to build resiliency in the grid in times of disturbances, as you add more renewables, you have less intermittency and you need also to have functions where you can support the grid.
00:14:33.282 --> 00:14:44.595
We have also something that we call grid forming capability where you can, through the power converters, you can help to stabilise the grid from a frequency and voltage perspective.
00:14:45.075 --> 00:14:53.105
When you have maybe issues in the AC grid, can use the converter to stabilise both the voltage and frequency.
00:14:53.105 --> 00:14:56.065
So that's kind of an advantage when you do kind of interconnectors.
00:15:24.974 --> 00:15:29.099
And what does that change strategically for Europe and North Africa?
00:15:30.733 --> 00:15:37.573
I think for North Africa is strategically for them, given how much sun you have in, in the Sahara.
00:15:37.573 --> 00:15:44.486
If you can make this politically show that it's stable, you can be a trusted party to Europe.
00:15:45.416 --> 00:15:53.426
In theory, you could add a lot of clean energy from Africa to Europe, especially to part of Europe.
00:15:54.396 --> 00:16:07.326
And it's fairly cheap as well to build if you compare to build solar power in Africa, flatland desert compared to build it in Greece or hilly Italy and so on, it is of course much cheaper.
00:16:07.326 --> 00:16:17.201
So you can get cheaper energy, you can get clean energy and you can get the energy that helps to secure your resiliency as well when you interconnect.
00:16:17.666 --> 00:16:25.191
So there are many benefits both from Africa and the African and northern countries, but also as Europe quite a lot of benefits.
00:16:25.356 --> 00:16:34.966
You get cheaper energy, you get flexibility and at the end you can connect energy up to the northern part or central part of Europe as well.
00:16:35.386 --> 00:16:42.087
And you start then to be able to support and that's what the European Commission wants with the grid package.
00:16:42.526 --> 00:16:52.426
More interconnection can help to stabilise the whole grid and bring cheap energy from the north with the hydropower and the North Sea with the wind and then the sun from Africa.
00:16:53.333 --> 00:17:06.182
It doesn't go over a, a day or a, a year or two, but over the decades and you talk 2040, there is a lot that can be done for the society trying to tie these energy systems together.
00:17:07.271 --> 00:17:07.541
Right.
00:17:08.622 --> 00:17:16.092
And of course, Europe and Africa have kind of a, a chequered history.
00:17:16.961 --> 00:17:25.991
Are projects like this being done sensitively to make sure that we're not just extracting value from North Africa without giving anything back.
00:17:27.439 --> 00:17:29.298
You mean that Africa gets anything back
00:17:29.703 --> 00:17:30.453
Yeah, exactly.
00:17:30.693 --> 00:17:31.173
Exactly.
00:17:31.173 --> 00:17:33.028
In terms of community benefits or things like that.
00:17:33.328 --> 00:17:33.687
yeah.
00:17:33.687 --> 00:17:45.130
I, you know, I, here, I must say that of course Tunisia get paid for the energy that we buy, and so it's a clear business proposition for them as well to sell that energy.
00:17:45.130 --> 00:17:56.410
So there is a return of investment for sure, for Tunisia as well doing these kind of projects as it is also for Italy to do it, because of course they see a return on investment.
00:17:56.450 --> 00:18:00.000
So you can see it either from a financial perspective.
00:18:00.000 --> 00:18:00.600
Yes.
00:18:00.650 --> 00:18:02.539
I believe that there is a clear benefit.
00:18:03.110 --> 00:18:05.750
You can see it from a community perspective.
00:18:05.870 --> 00:18:09.019
You create a job to construct the projects.
00:18:09.019 --> 00:18:21.407
You create service opportunity for people, and you create an opportunity to develop your workforce to be a skilled workforce, in Tunisia as well, and over time.
00:18:21.407 --> 00:18:26.711
So I think it, there are many benefits that that comes with these kind of complex and large projects.
00:18:27.745 --> 00:18:28.015
Cool.
00:18:28.345 --> 00:18:28.615
Great.
00:18:29.215 --> 00:18:33.505
And of course, drawing lines between countries and a map is, is easier than building them.
00:18:33.505 --> 00:18:40.404
So without getting technical, what does HVDC allow us to do that conventional transmission might struggle with?
00:18:41.307 --> 00:18:43.077
So that's a, a good question.
00:18:43.077 --> 00:18:46.468
And these, connections are long distance.
00:18:46.587 --> 00:18:53.708
And long distance normally you have quite a lot of losses through AC .You can say 10% losses.
00:18:53.738 --> 00:18:57.803
While in DC you have maybe up to one, one and a half, 2% losses.
00:18:57.803 --> 00:19:02.918
So it's quite a big difference in terms of losing energy when you do long distance transmission.
00:19:03.758 --> 00:19:19.988
If you want to connect the northern part of of Africa and if you to
say, okay, I want energy in Italy, from Africa on AC you can of course go to South Spain and then build transmission through Spain and around France and back in into Italy.
00:19:20.317 --> 00:19:22.418
Very costly and very time consuming.
00:19:22.418 --> 00:19:27.158
And of course, permits is, is an issue to get when you want to build on land with overhead lines.
00:19:27.817 --> 00:19:30.337
So that's a, a drawback of doing it in AC.
00:19:30.394 --> 00:19:39.938
While on DC you can just lay a, a cable and if it's more than a hundred kilometres you go DC because of loss system and problems to do it on an AC cable.
00:19:40.928 --> 00:19:42.158
That's the real benefit.
00:19:42.307 --> 00:19:47.178
You can connect long distances very effectively and it's also more affordable.
00:19:48.155 --> 00:20:09.536
Right, and I, I've seen reports of HVDC in China where they're connecting western China, where there's a lot of renewables generating electricity to eastern China where there's a lot of consumption and we're talking distances of two, three, 4,000 kilometres and they're transferring gigawatts of electricity.
00:20:09.536 --> 00:20:11.871
So it's, it's incredible feat of engineering.
00:20:12.559 --> 00:20:18.620
It, it is, and we are, as Hitachi Energy, quite heavily involved in, in supporting the customers in China.
00:20:18.620 --> 00:20:24.150
And we have this 1100 KVDC project that we built together with them.
00:20:24.150 --> 00:20:30.897
And it's more, was more than 3000 kilometres distance, 12 gigawatt of energy So it's quite a lot.
00:20:31.817 --> 00:20:46.797
That, if you compare to Europe, for example, but also US you need to have a very strong grid to be able to receive such amount of power and to lose, you don't lose 12 gigawatt in one, but maybe you can lose three, four gigawatt depending on the configuration.
00:20:46.797 --> 00:20:53.086
While in Europe we have set our guidelines or grid codes to not lose more than two gigawatt.
00:20:53.957 --> 00:21:00.307
So that's sort of why we build this systems that are not more than two gigawatt in Europe for the time being.
00:21:00.977 --> 00:21:05.836
And in United States, you have three gigawatt, as the maximum loss.
00:21:08.497 --> 00:21:15.427
And what would you say then has proven harder than you expected about modernising grids?
00:21:16.750 --> 00:21:22.870
I must say, Tom, interestingly, I think we are timely having the right technology.
00:21:24.009 --> 00:21:33.970
So just building more of the AC, it's more about us adding more capacity, transformers, switch gears, engineering, et cetera, and we are on that path.
00:21:34.049 --> 00:21:35.220
So that's not an issue.
00:21:35.220 --> 00:21:43.130
If you talk about power electronic solution where HVDC is part as well the technology is available also to build the future grid.
00:21:44.070 --> 00:21:57.385
I think what is really problematic is that the scale is so big and of course we need to coordinate or do it a bit differently as, as a community.
00:21:58.066 --> 00:22:04.456
For us, it doesn't work when customers go to market and say, I want one project here, one project there, and so on.
00:22:04.875 --> 00:22:11.836
Our view is that we, we need to have more kind of frameworks or to create synergies and affordability as well.
00:22:12.586 --> 00:22:15.286
It's very expensive to do one project at a time.
00:22:15.996 --> 00:22:27.895
And maybe the third one is of course the, I think grid planners are taking a by surprise about giving permits to build because the queue is so long.
00:22:27.956 --> 00:22:37.732
And so the timing there is, is a real concern for, me that we see some projects slipping because they don't get consent to build just because of the queue.
00:22:37.803 --> 00:22:40.393
And that is concerning I must say.
00:22:41.843 --> 00:22:44.817
So that, that is a piece where I think we could do better.
00:22:45.844 --> 00:22:46.653
How do we fix that?
00:22:47.802 --> 00:22:49.192
I think you need to reform.
00:22:49.662 --> 00:22:54.682
Today it has been, you know first comes, first serve in, in terms of getting in grid connection.
00:22:55.612 --> 00:23:04.251
And you, I think you need a holistic view on the network and say, okay, I do have to prioritise generation with transmission and consumption.
00:23:05.102 --> 00:23:06.211
How to do this?
00:23:06.241 --> 00:23:09.872
It's of course up to the strategy of countries or regions.
00:23:10.542 --> 00:23:18.692
It's not an easy one to fix because you can be, you can feel that you be unfairly treated, of course if you're not pushed up in the queue.
00:23:18.692 --> 00:23:25.832
But as a society, I think we need to work on finding a priority depending on what we want to do.
00:23:26.113 --> 00:23:36.612
If you want to electrify the vehicle fleets, you need to build depots, et cetera, and then you need to get access to electricity, otherwise it doesn't work.
00:23:36.792 --> 00:23:38.501
And then you need to put priority on that.
00:23:38.674 --> 00:23:51.805
If you want to build data centres and have them close to for example, financial districts or whatever, to have speed, or you want to have AI data centre, you need to have access to electricity, and then you have to have priority on that.
00:23:51.845 --> 00:24:02.805
So if you want to add maybe one windmill of two three, five megawatt, just because you want to be investing it, maybe that's not the right priority for the time being, for that grid connection.
00:24:02.805 --> 00:24:07.424
So you have to have a, a strategy behind it, which has been lacking a bit so far.
00:24:08.235 --> 00:24:08.505
Okay.
00:24:09.642 --> 00:24:13.662
And that's where grid planning stops being a purely technical exercise.
00:24:14.412 --> 00:24:24.677
If access to power determines which factories, depots, or data centres get built, connection policies starts to look a lot like industrial policy.
00:24:26.077 --> 00:24:32.107
Would you say national grids are
eventually going to become the wrong mental model for electricity?
00:24:33.222 --> 00:24:41.083
I think of course transmission grids needs to be there to, to move bulk power to load centres from generation is very important.
00:24:41.083 --> 00:24:46.363
But I also see that micro grids, so grids, yes, you are right Tom.
00:24:46.363 --> 00:24:55.783
I think that is enabling the energy transition, but it doesn't have to be the old mental model where you have generation, transmission, distribution.
00:24:55.783 --> 00:25:02.033
I think you will have more ecosystems where, things are collaborating more across grids.
00:25:02.033 --> 00:25:26.133
And one thing that we are thinking of is if you take cities like Mumbai and really dense populated cities where it's not so easy to build new infrastructure and you have generation around a lot of solar and wind maybe you need just to have a small and medium voltage DC to, cut cross two, distribution segments and so on.
00:25:26.133 --> 00:25:36.333
So I think there is also maybe a reform to be made between distribution companies and transmission companies on how you collaborate to make this effectively.
00:25:37.070 --> 00:25:44.990
And what's one development you'd watch as evidence that we've genuinely moved from talking about grid transformation to actually delivering it.
00:25:46.497 --> 00:26:00.317
What is really going to be a, fundamental shift is if we are able to create an offshore grid or an offshore generation area where several countries can collaborate.
00:26:01.487 --> 00:26:07.997
And that's not easy because it's also all about rules and priorities and guidelines.
00:26:07.997 --> 00:26:23.932
And maybe you even need a transmission operator offshore that collaborates several countries So maybe we need that and, and that is of course would be in evidence when we start to see that several countries collaborate in building out the North Sea.
00:26:24.563 --> 00:26:26.043
'cause that's also more affordable.
00:26:26.753 --> 00:26:28.702
We have to build point to point.
00:26:28.843 --> 00:26:33.743
You can actually use one to three, four countries if you want.
00:26:34.498 --> 00:26:36.023
And that is in evidence for me.
00:26:36.083 --> 00:26:42.653
If that happens, then we have actually achieved a big fundamental shift in, how we build the future energy system.
00:26:43.931 --> 00:26:44.230
Super.
00:26:44.471 --> 00:26:45.321
Okay, Niklas.
00:26:45.341 --> 00:26:52.211
It's time now for the lightning round where I ask three or four questions and you get one sentence answers.
00:26:52.211 --> 00:26:52.596
You ready for that?
00:26:52.941 --> 00:26:54.201
Yeah, I try.
00:26:55.045 --> 00:26:55.945
Okay, great.
00:26:56.575 --> 00:27:00.025
So build early or wait for certainty?
00:27:01.380 --> 00:27:03.299
Build early when they talk about transmission.
00:27:05.004 --> 00:27:05.304
All right.
00:27:05.933 --> 00:27:08.244
More generation or stronger connections?
00:27:09.796 --> 00:27:15.166
We need more generation to do the electricity and energy shift we need.
00:27:16.913 --> 00:27:20.058
Okay, faster approvals or more investment?
00:27:21.688 --> 00:27:23.388
Faster approvals and more investment.
00:27:26.186 --> 00:27:28.436
National self-reliance or shared resilience?
00:27:28.910 --> 00:27:29.840
Shared resilience.
00:27:30.621 --> 00:27:30.861
Right.
00:27:31.295 --> 00:27:33.095
What's the most expensive grid mistake?
00:27:34.725 --> 00:27:35.355
Not building.
00:27:36.987 --> 00:27:38.914
Okay, Complete this sentence.
00:27:39.423 --> 00:27:41.558
Clean electricity only counts when…
00:27:43.096 --> 00:27:44.836
When it can be brought to the consumers.
00:27:45.970 --> 00:27:49.437
Yeah, Is the grid essentially the logistics system for electricity?
00:27:49.437 --> 00:27:53.606
I mean, we can produce all the clean power we like, but generation is not delivery.
00:27:54.793 --> 00:27:54.893
No, exactly.
00:27:56.173 --> 00:28:12.814
Okay, time for a left field question now Niklas, if you could have any person or character, alive or dead real or fictional as a champion for grid modernisation, who would it be and why?
00:28:14.303 --> 00:28:16.593
I would have to pick Uno Lamm actually.
00:28:16.613 --> 00:28:25.222
He's the father of HVDC and he took 20 years to innovate the first HVDC link between Sweden, mainland and Gotland.
00:28:25.942 --> 00:28:27.893
And we are still building on his legacy.
00:28:28.503 --> 00:28:42.533
He was a fantastic engineer, a visionary, and brought a lot of innovation into the energy system and I must say he's a fantastic person that is still impacting the energy system of today and in the future.
00:28:43.011 --> 00:28:43.282
Great.
00:28:43.778 --> 00:28:45.138
Niklas, that's been really interesting.
00:28:45.258 --> 00:28:47.028
Thanks a million for coming on the podcast today.
00:28:47.273 --> 00:28:47.993
Thank you, Tom.
00:28:48.323 --> 00:28:49.013
Nice to talk to you
