Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow
Allen Hall: Alejandro, welcome back to the program.
Alejandro Cabrera Muños: Thank you so much, Allen. It’s a pleasure to be here.
Allen Hall: Well, so last time we talked, you had so much happening at Green Eagle, and it is, uh, amazing to watch the progress there. You’ve been around for quite a while now. You started, what, in 2011 working on SCADA systems.
Uh, uh, there’s been a lot of evolution since then. Walk me through, like, the process where you thought, “Hey, there’s a business here.”
Alejandro Cabrera Muños: Of course. Uh, we actually started officially back in 2012. It’s been a, quite a, of a long journey to, to get here. Uh, yeah, we started, uh, back, back then. We say it’s a whole new world, right?
If we look backwards, like, almost 15 years. Makes me, makes me feel, like, extremely [00:01:00] old. Uh, but ne- nevertheless, um, yeah, back then we were trying to, to cover, like, a lot of issues that were based on OEM SCADAs, which by the way, we still are dealing with. But, but that, that was starting point. It was, um- It was, uh, based on understanding that the, the renewable energy industry is so complex.
Every wind farm, every solar plant has different issues, different systems. Even, even the same models from the same manufacturer sometimes have complete different systems, which complicates everything. So it was very exciting to, to start our careers in a, in an industry where nothing is standard and where everyone is looking for something that is standard.
So that’s, that’s where we fit in. Um, yeah, and in these years, we, we started basically creating the f- the foundations, uh, uh, on top of, uh, SCADA systems. [00:02:00] But as soon as we had that, those foundations, we realized that this sector is not gonna evolve, uh, it’s gonna cope up with the complexity, uh, of the technical complexity, market volatility, regulatory compliance.
That’s not gonna be solved by just having more SCADAs. So we created a layer of automation in place, which is basically what we’ve been, um, evolving in the last 10 years now, um, with the, with the mindset and with the goal that every wind turbine should be running autonomously without having to have people behind it, uh, supervising and taking control of it.
Allen Hall: Yeah, and that’s a great founding idea, but that has grown from an idea to you’re automating, what, 40 gigawatts of renewable assets right now?
Alejandro Cabrera Muños: Oh, we’re actually now connected to over 70 gigawatts.
Allen Hall: That’s amazing. Alejandro, that’s incredible.
Alejandro Cabrera Muños: And all of them are different.
Allen Hall: Sure. So that, that’s a combination– 70 gigawatts is a combination of wind and solar and anything else?
Alejandro Cabrera Muños: Yes. [00:03:00] Well, actually, one of the, one of the main, um, needs that we try to cover from day one is to be able to connect to all, um, asset classes. So we understand that, um, the challenge of operating a large portfolio for our customers, um, can only be solved if we have the ability to connect to all type of asset classes.
So we can have to connect to wind turbines, inverters, trackers, substations, um, energy meters, you name it. You– we have to connect to every single asset class, um, because what’s important is how you manage that data on top of that and how you react on the anomalies.
Allen Hall: Right. Because I think a lot of operators are now considering taking your model, the Green Eagle model of s-self-operating, but they need that help, they need that insight into the operation of a solar farm or a wind farm or, or any of those assets, renewable assets, ensure those inverter-driven assets.
You’re, you’re seeing– I, I think we’re seeing the same thing, which is a lot of operators decide to [00:04:00] leave full service agreements globally, and what do you think is driving that now? Uh, is it a financial decision? Is it a performance decision, or is it both?
Alejandro Cabrera Muños: I think there are many factors, but I think the main driver is the financial aspects of it.
I think when you, when you delegate the operations to a third-party, uh, entity They are gonna optimize their services to whatever service level agreement or availability they are committed to. And for that reason, you’re never gonna get– effectively, you’re never gonna get the extra mile. You’re never gonna get any extra from there.
Um, and that’s okay when the market is– has great conditions and everything w- is going well. But we are seeing how in the last years we have, uh, a lot of market volatility, negative pricing. Everything is becoming more and more complex, so many projects are actually under stake financially. And I think that’s, um, that’s pressuring everyone to look for opportunities to squeeze their assets a little bit more or a little bit better, I would say.[00:05:00]
Um, and part of that is to take operations in-house so you at least you have the opportunity to, to do, um, a better job, uh, let’s say.
Allen Hall: Yeah, and part of what we’re seeing is, at least in the United States and, and globally now, I think it’s, there’s more action globally than there has been on mergers and acquisitions.
So an operator that has historically had a particular OEM in wind, you know, say it’s Vestas or Siemens or GE, whoever, Nordex, it could be any of them. Uh, when they acquire another competitor or another farm, they’re bringing in a f- a wind turbine they probably don’t know much about. And, and that’s a huge problem.
And, and there’s not a lot of resources for them to grab hold of. Uh, that’s one of the marketplaces you’re trying to fill right now, right?
Alejandro Cabrera Muños: Of course. Uh, as I mentioned before, if something describes our sector is that nothing is standard, despite everyone is seeking standardization of everything, right? Uh, but nothing is standard for, [00:06:00] for– and that, that’s the reality.
So the first thing when, when you have a portfolio and you are incorporating new assets into it, you need, um, a solution that is able to connect to all type of assets, right? Um, w-we call our solution a three-in-one solution because first of all, it acts as a second level SCADA, so you can connect everything there, uh, everything there, and you have access to all the data across all your assets.
Then we have the SCADA automation layer, and then we have the data analysis layer on top of that. Okay. But let’s focus on the operations, which was, uh, your question, right? So you have a new bunch of assets. Sometimes you don’t have any documentation whatsoever, but these are Gamesas, Nordex, a bunch of them from different years.
Um, the first thing that we provide is a second level SCADA, so you can connect to all of those. But We have, uh, something that we believe is very unique. So what we provide to our [00:07:00] customers is ability to automate all these assets autonomously. And what that gives you, it’s, um, set of data that can be analyzed, and we can learn from what’s working, what’s not working, beyond what the manufacturer’s gonna tell you to do, right?
So we have thousands of General Electric turbines connected to our software, for instance. Um, we know what works, what doesn’t works, uh, what are the faults that can be resetted remotely, what are the ones that are not, what is the success ratio of those resets, ’cause that’s a metric that nobody else has unless you have automation in place.
Uh, but we can actually understand, is it working? Is it not working? Is it creating fatigue for no reason to these turbines? So what– we have all this, this, uh, un- this knowledge and this, um, knowhow, uh, for all these models. Um- I believe one of the main, um, value that we provide to our customers is, is not only the, the solution itself, but it’s also the [00:08:00] ability to be somehow prescriptive.
It’s, it’s not that we’re gonna know more about how to operate the assets than our customers, but, uh, we have a sense of what’s the benchmark, right? So I, I– And that benchmark is very, very useful for them as well.
Allen Hall: So th- that’s part of getting to scale, and 70 gigawatts is a, a lot of scale, where you have seen a number of turbines in different places operating in different environments and performing at different levels.
That’s unique, right? That gives you insight into really what’s happening to a turbine or a solar asset globally and also locally. For a lot of operators that just happen to acquire or, or, or take on a- an older wind farm, uh, they tend to get stuck, right? They, they, they, they don’t tend to be able to, to find their way through those little nuances.
That’s a huge financial impact to them eventually, right?
Alejandro Cabrera Muños: It is. And I, and I believe that for many years this was something that in a way got, um– [00:09:00] didn’t get a lot of visibility. I think people were not fully aware of how much revenue, how much production they were losing just because they were not operating their assets at the best capacity.
Um, now we have the data to prove what, what better can look like. W- uh, we have data to prove that if you follow the OEM’s, uh, protocols, you may be creating fatigue for no reason. Um, and there are improv- there are ways to improve that thing. So I think it’s, um– We are, we are opening the door for a new, complete new way to operate your, your portfolio and get more benefit from it.
Allen Hall: I think that’s a very interesting aspect of the sort of the structural aspects of how a, a wind turbine performs, and a lot of that is driven by software. And you, you realize if you’re paying close attention to the OEMs that some of the software updates are not necessarily performance enhancements.
They’re more of protecting the turbine because they realize they may have a problem. So it may be a slight derate, it may be a, a different sort of power curve that happens. [00:10:00] But a lot of operators don’t really sense that that is happening up close because they’re not into the details of that. That’s where Green Eagle separates itself.
You are into all those details. And do you have a lot of operators just reach out for help immediately saying, “Hey, I have this Siemens Gamesa or Gamesa wind farm,” think about an older wind farm, a Gamesa wind farm Help. Just please help. Uh, whatever you can do, just show us you can do it. Do you, do you start to run a little test campaign on that site, or do you, or do you go pull back from the 70 gigawatts and 15 years of history to, to show this is what you can do with that particular asset to, to get them involved in a thinking about the problem a little bit differently?
Alejandro Cabrera Muños: Well, I wish, I wish it was that way. Um, but what, what– It, it was that transparent, but what happens is that we’re working with the largest, uh, some of the largest utilities and IPPs in the world. So what happens is that they, they will never come to us saying, [00:11:00] “We don’t know how to operate this turbine,” or, “We don’t have enough information.”
Um, the way they ask for it is like, “Are you compatible with this?” And, “Do you know… Do you have some protocols? Do you know the standard protocols to run these turbines?” Um, and that’s the way we, we start the conversation, and then they, uh, they, they get confident that we can actually help them with that. We only know about how, how much or how little they know about a specific model once we start working with them.
And it’s not all or nothing. I- Ev-Even the largest manufacturer, e-even the largest utilities, their portfolio is constantly evolving. They’re incorporating new sites almost every month. So there’s always one site that they don’t, they don’t have expertise in the, in the house, so it’s, it’s normal. Like, basically not many people have expertise in some of the models from old Nordex or Gamesas or you name it.
It, it’s impossible basically to have to understand all models in the world. So I think we [00:12:00] have the, the data, the benchmarks, and experience, and on top of that, the of course, the, the tools, so you can actually operate better those, those assets.
Allen Hall: So the name of your system is called ARSOS, A-R-S-O-S, and for anybody listening to this podcast, you can just Google it, and it’s gonna take you to Green Eagle.
What is that product? How would, how would you define or describe that product?
Alejandro Cabrera Muños: Well, ARSOS is a suite. Um, what– The way I like to think about it is a, is a three-in-one solution, right? So it’s first of all, it acts, it, it, it fits in between the SCADA world and the REMs, uh, the REMs, uh, solutions. Okay? And they’re complete different worlds even though you see dashboards and they look the same thing.
But SCADAs must be, um, must be able to be installed on premises. They require OT enterprise cybersecurity level. They can be, they should be installed on air-gapped infrastructure, so no access to internet whatsoever. [00:13:00]Um, and that they tend to be extremely complex to configure and, and, uh, adapt to every, uh, every different site.
So that’s one world. Um, on the other hand, we have the, the REM solutions that are like more like a SaaS platform, like a Power- it could be Power BI, it could be like the, the normal use cases that you need it. You need something, some tools to create the reports at the end of the month to understand the performance of your assets, right?
So you have these two, two worlds. So what we are proposing here is a solution that has been built for the past 15 years, but it fits right in the middle. So it covers Almost everything that you need from a SCADA and second level SCADA solution. It puts automation in place, and then it also gives you all the data so you can consume it in the best way, uh, possible, which by the way, now with, uh, artificial intelligence, it’s incredible what you can do with it.
So this is basically what we have built, um, right [00:14:00] now. And the main differentiation here is that since we are in the middle, we are trying to solve all this complexity from a SCADA world with a product that is already pre-configured. So you can basically connect to your sites in a completely easy way, um, doing clicks and not a lot of complexity because it’s already pre-made for your needs.
Um, because of that, the time to market is extremely much, uh, faster compared to a SCADA solution, so you can have a solution in thing, in hours and not in months. It’s, it’s not a project anymore, right? Which is, which it sounds like normal when you, when you talk about applications, it sounds like a normal thing to do, that you have a, a system running in hours or minutes.
But when you’re talking about SCADAs, that’s like sci- uh, sci-fiction, right? Um, that’s what we’re bringing to, into, onto the table. It’s, it’s, uh, something that you can connect to all your assets in a seamless way, painless, and, uh, and, uh, off the [00:15:00] shelf.
Allen Hall: Well, that’s a very interesting way of framing, uh, the product because, uh, you do see both ends of the spectrum here, where y- there’s a number of companies that are offering a c- completely SaaS product, which is a very pretty dashboard, and it still relies on a human to watch this dashboard and, and to make sense of it, and it provides some insight.
And then you get to the other side, which is almost a completely mechanical system, where it’s just SCADA data and, and you’re just picking up data for datas, uh, to have, basically. So you, you f- you sort of find that middle ground. The, the, the amount of software and technology that it’s in that space, though, must be huge, and what is the effect of AI bring to you?
Does that help you more with just on the, on the, on the model side or just the, the statistical analysis of all the data that you have access to now?
Alejandro Cabrera Muños: Let me make a, um, clarification. Because since, uh, we are, we are providing automation [00:16:00] in a world that is mission critical, right? So there’s no, a lot of, there’s no room for creativity or probabilistic approach.
It all has to be the deterministic, right? Uh, so when we talk about automation, we’ve always been focused on deterministic automation, so rule-based, uh, automation, and that’s what we have implemented on top of the level of the SCADAs, right? So that’s, that’s the part where you know how to deal with an asset.
You have the protocols. You want to understand how they work, but you want to have certainty of what happens if the turbine is on fault and the fault is related to the gearbox temperature and so on. So you wanna make sure that there’s a reset automatically executed only if the temperature of the gearbox is under X threshold.
So this very deterministic approach. Uh, but we have, uh, something, um, very unique when we go on the, on the other side, when we go on the side of the REMs. Because we not only have the data of, of the assets, we [00:17:00] not only have statuses, performance, availability, uh, production. We also have the data of how these assets, assets have been operated, right?
So we know how much fatigue they have received, how they’ve been operated, um, have they received curtailments or not? How many curtailments? What were the reasons? So we can actually have a 360, uh, degree of all the data, including all the control, not only how they’re performing, but also how we are operating those assets.
And we believe that this is very unique because only if you have all these 360 data, then you can actually enhance what you have on top of that. And that is where AI come, comes in, right? So AI, AI is great in, um, helping our customers in doing root cause analysis, um, dealing with anomalies are not well, um, uh, procedure.
Uh, there’s no course of action that is clear, that you don’t know. It’s, they’re not like too [00:18:00] frequent to, to have one. Uh, mixing different type of data. Like I mentioned before, you have, uh, market data, you have curtailments, you have, uh, commands to stop or start a turbine. You have a lot of information there, and you can put all together.
Uh, also along with the CMMS information. Um- Lastly, they get– they can pull that together to do whatever they need, right? Uh, they can build with AI. You, you can now do your own dashboards. You can create your own APMs if you wanted to. Um, and I like to think about it, like, with these new tools that you can create disposable dashboards.
And, uh, the concept is that it doesn’t matter how many different dashboards you have in an APM, but tomorrow you have a, a specific case. And I think it’s amazing that now with AI and the right, uh, data structure, you can now create a dashboard, and maybe it’s just for one use case, you know? And you just build it today, look at the data.
You have [00:19:00] a, um, a case study, and that’s it. May– you never use it that again. The trick for being able to, to, to create this ecosystem where you analyze the data in a completely different way is that we have been working on how to structure the data so the AI is gonna be able to understand the data itself.
So once that, that layer is structured in the right way, then you can actually create your own APMs or your own dashboards as you need to.
Allen Hall: That’s fascinating. So instead of just thinking of a turbine or a, a solar field as a asset where you’re trying to maximize performance necessarily, you’re looking at it from the marketplace, the, the, uh, the shutdowns, all the, the things that are contr- overriding the performance and trying to optimize performance in this market environment, which may be very turbulent, and I think for a lot of wind operators is very turbulent, uh, at, at the minute just [00:20:00] because of the nature of the electricity grid.
So you’re, you’re then thinking about Having an AI tool to help you do investigative work on the particulars, not just the global data set of how this turbine globally operates, but the specifics, that’s fascinating because that allows you then to treat each turbine as its own separate power plant, in a sense, but also to, to think about lifetime issues and how to maintain that piece of equipment in a much more efficient way.
That’s remarkable.
Alejandro Cabrera Muños: And you have the– With AI, you also have the capabilities to automate all these type of analysis. So once you have a specific, uh, case to be analyzed, then you can automate that case to be analyzed in a daily basis, in a weekly basis. But that’s, uh, that, that’s, uh, that’s, uh, the world that we are moving to.
Allen Hall: So a lot of what’s happening at Green Eagle at the moment is being automated and, and making it easy for, for customers to get [00:21:00]onboarded to the RSO system. What does that look like today? Uh, how do, how do I get onboarded? I have an asset of I got 1,000 turbines and a couple of solar fields. What does it look like to get me started in the RSO system with Green Eagle?
Alejandro Cabrera Muños: Well, if you’re using our cloud, it’s, it’s gonna be a process of If you have a, a portfolio of 500 gigawatts, you can connect to our, to our cloud in a matter of like one month to two months So that’s something that you can do by yourself. So, um, you can create the assets, you can create the connectivity.
The connectivity is done through IP filtering or VPN tunnels. All that is from the, from the dashboards, from, from the cloud. Um, then you can, based on the model directory, you can choose which is the, the assets that you want to connect to and through what channels, whether you have Modbus, OPC, and so on.
Um, but that’s a- as complex as, as it gets. Really? It’s n- it’s not easy either, because [00:22:00] you need to understand what is a Modbus, what is a OPC, but that’s what it is. It, it’s not a matter of, like, installing something on site and doing tons of, uh, complex, uh, um, configurations. You don’t need, uh, SCADA engineers to be, like, building these dashboards tailor-made for your sites and, and all that is, is something from the past in o- in our opinion.
Allen Hall: So you’re not on the telephone, or you’re not on a, a online chat with the Green Eagle team, because it’s, it’s, it’s– you’ve, you’ve done enough capacity now that you’ve automated this.
Alejandro Cabrera Muños: You don’t have to.
Allen Hall: That’s amazing, because I think that’s the first worry for any operator that is gonna make that leap saying, “Hey, I need a little bit of help with this wind farm or this solar site,” is that, “Oh, I gotta be on the phone.
I gotta– There’s a lot of im- of onboarding that has to happen,” and you’ve eliminated that.
Alejandro Cabrera Muños: Well, first, w- I, I totally understand this hesitation. Um, many of our customers are living in, in the, in the SCADA world, right? Uh, and which w- it was probably once a pain [00:23:00] to be configured to begin with, and I think half the sector is traumatized by these processes.
So I, I tot- I totally understand that that pain is, is still there, right? I understand that. But what we’re trying to do is to, to move forward and say like, “Yeah, that, that’s gone. That was the past. Now we have a different way to do it.” And if you have, uh, either new assets that you need to connect or you even consider, like, moving to something more modern, something with more capabilities, something that comes with automation in place, uh, well, we have a solution that is painless.
Allen Hall: Can I discuss, or can we go back and forth about the, the use of inverter-based resources, the solar and the wind sites, in terms of the, the move from grid following to grid forming and stabilizing the grid? I think there’s gonna be a lot of changes in the way that we operate these assets over the next year.
Mostly, uh, I see action in the United States from the Iberian blackout about a year ago. They’re changing the thought process of how they want to run the grid so that the wind [00:24:00] and solar can keep the grid operating. Is– Are you involved in, are you involved in that aspect of how you operate those assets and how those inverters perform and, and configuring them to, to do more of the, of the grid forming and keeping the grid stable?
Alejandro Cabrera Muños: I believe, to be honest, this is more related to power plant controllers and hybrid plants. So we have, we have made several projects with, um- With a mix, uh, of, uh, wind, solar, um, and storage. And wh- but what we’re doing here, uh, to be completely honest, we are not involved in the power plant controllers. Uh, we believe that that’s an electrical device and has, uh, uh, particularities that are out of us- our scope.
But what we do is to, again, we connect to all asset classes, right? So we also w- connect to the PPCs, and we can monitor the PPC, the performance of the PPC, and we integrate that into everything else, right? So [00:25:00] that’s, for us, that’s another asset that we are connecting to, and that it make– it completes the view of, um, of sites that are now, like, almost like mini portfolios at, at the same place, right?
‘Cause you have, uh, different technologies, service stations. You have so many things that you need to orchestrate as well. So we’re, we’re w- moving into, into that area as well, uh, f- with the same concepts.
Allen Hall: B- so in a, in a sense, you’re able to monitor the health or status of the grid. Because you’re connected to so many of these assets, you have a pretty good understanding of how the grid is doing at any particular moment then.
Alejandro Cabrera Muños: That’s right, yeah, especially in, in Spain, of course, ’cause we’re connected to, um, over 25 gigawatts at the, uh, at, in Spain, so.
Allen Hall: Alejandro, that’s amazing.
Alejandro Cabrera Muños: Over 25 gigawatts at the, uh, at, in Spain. So, so that’s s- it’s almost a third of the, of the installed capacity in Spain.
Allen Hall: Is there a movement in Spain to, to use technology like yours [00:26:00] to better monitor, regulate, control the, uh, wind and solar assets so- such that they stay engaged when, when the, the grid starts to, to vary a little bit?
Has anybody asked you to, to be involved with that? Because it seems like you’re the right– you’re in the right place at the right time.
Alejandro Cabrera Muños: The challenge of all these grid codes, uh, in, in most of cases is just that There are tons of curtailments that are coming from many different reasons, technical restrictions, market, uh, dispatch, um, other type of compliance.
Um, the, the first challenge is to just execute on them, right? So they’re coming, you need to apply on the, on the sites. Um, that was the first, the first phase. But now that we have so many gigawatts connected, and that we’re also participating in balance mechanis- balance mechanisms and ancillary services, what we are seeing is that depending on how your assets perform and how quickly they are in regulating, um, you are gonna [00:27:00] have penalties or more, uh, profitability in the participation of the markets.
So that’s, that’s extremely important as well ’cause it’s, it’s quite difficult to, to measure. But we have all the– Since everything is automated, you can always track, and you can statistically understand which of the sites are performing better or worse, in what cases, and therefore you have opportunities to improve the regulation and get more revenue from it.
Allen Hall: Okay. So Green Eagle then is, because of the scale that it has at the minute, can look at the grid and is involved in, in the, the grid requirements, so to speak, of, of, uh, curtailments and what assets are operating when, and also the voltage control aspects and frequency control, which is the other part of it.
You, because you’re, because you have so many assets in Spain and globally, you, it’s amazing the number of assets you have. You, you then can actually, one, see health of the grid, two, [00:28:00] provide insights to operators on what that looks like. I mean, real time you could, you can do that. And then are, are, are the regulators then coming to, to you asking advice on how these assets should perform?
Because it does seem like you would be a tremendous resource on how the grid is actually doing on a larger scale from a renewables standpoint.
Alejandro Cabrera Muños: Yeah. Well, fortunately, the, the regulator has its own also, uh, system, so it’s, uh, redundant, right? So as far as we, we are working to, to have, uh, the best system in the world, but, but it will be a lot of, uh, responsibility for us to just have the whole grid depending on us.
That would be a lot of weight. Uh, but in a, in a way, in, in a, in a way, it already depends on us, uh, effectively. So, so the pressure is, is there. We have, we have talked to them, um, since we have so many customers, um, in the, in the– at this level, uh, we have to be very quick in implementing new grid codes and new [00:29:00] regulatory, uh, compliance issues and, and so on.
So that’s, that’s, um… It’s a challenge, but at the same time, it’s, it’s very exciting that we are always ahead in, in this regard.
Allen Hall: Right. If, if I was an operator and I had Green Eagle as one of my, uh, helpers in a sense, uh, assistants in a sense, that helps with the, the grid code i-in terms of, one, understanding it, and two, being able to implement the changes that are coming down all the time.
You have a resource there that understands it from a larger perspective because you see it from multiple operators in multiple places trying to do the same thing. That’s a huge advantage instead of you trying to na-navigate or try to understand all those grid code changes and why they’re happening and what it means to you and how do you operate your assets.
So you can provide a little bit of guidance there for the operators.
Alejandro Cabrera Muños: Of, of course. Um, uh, the main, the main value proposition that we can have here for anyone that wants to participate or be part of the Spanish market is that we already have all this figured out. So if you wanna start from the scratch [00:30:00] with, uh, with a SCADA, industrial SCADA, well, let’s, let’s go with, let’s go with that.
You’re gonna be probably traumatized in the future, right? Uh, but with us you have an off-the-shelf product that is already compliance. It, uh, h- we have already set, uh, the system certified by the TSO in Spain. So we have already gone through this process so many times, and it’s off the shelf, so you don’t have to worry about any of this.
And on top of that, you have the Peace of mind that if tomorrow there’s gonna be a, a, a new change in the, in the, in a new grid code, well, which most likely is gonna happen, um, soon, uh, we have to, we have to do it. Because we have already, uh, a lot of customers that, that, that need it. So for us, it’s actually also, uh, strategic to, to be ahead and be fast in implementing these grid codes.
Allen Hall: That’s amazing. That’s such a huge resource for Spain and the rest of the world. Yeah, that’s amazing. Well, I, I know people who are listening to this podcast right now are thinking, “Okay, I haven’t heard of Green [00:31:00]Eagle, but now I’m interested, and I need to f- find out more.” How do they contact you? Where do they go first?
What’s the best first step?
Alejandro Cabrera Muños: Well, they can connect, uh, directly to me through LinkedIn, or they can just write to sales@greeneaglesolutions.com.
Allen Hall: Great, yeah, and Alejandro’s available on LinkedIn, so you can f- find him there. And we’ll put his contact information in the show notes to, so you have quick access.
Alejandro, you gotta come back more often because the, the things that you’re doing with Green Eagle are amazing, and, uh, the, the scale is incredible. Congratulations on that. Uh, and, and I, I, I need you to come back and tell us what the next generation looks like because I know when you guys get ahold of AI and start thinking through some of these real challenging problems, Green Eagle will have solutions.
So you’re welcome back anytime.
Alejandro Cabrera Muños: Super exciting to come back, uh, when you invite me. Thank you so [00:32:00] much.

And Mexico Will Pay for the Wall
One of the most remarkable characteristics of Donald Trump is his shamelessness. No matter how many lies he gets caught in, he’s always willing to tell one more–one that’s even more outrageous.
One would think that he and his supporters would eventually reach a limit, but the answer is clearly that such a limit does not exist.

Allen Hall 2025: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Matthew Stead, Yolanda Padron, and Rosemary Barnes is back this week.
Rosemary, you’ve been to a number of training courses over the last couple of weeks. The first off was GWO. What was your experience at GWO training?
Rosemary1: It was the fourth or maybe even fifth time that I’ve done it. Um, I did it a few times in Denmark and then, uh, this is the second time doing it in Australia. also, this was my first time doing first aid in Australia. Last time they did GWO here, but my first aid was still valid from Europe, so I, I didn’t redo it. And it’s like so much about [00:01:00] snakes and spiders and jellyfish But a good, good rule of thumb, not 100% accurate, but good rule of thumb, if it is something from the ocean that stung you, then you put something warm on it, and if it’s something from the land that stung or bit you, then something cold on it,
Allen Hall 2025: well, how often do you usually take GWO training?
Rosemary1: You gotta do it every two years to be valid. I don’t do it every two years because, um, if you do it every two years, like within two years, then you can do the refresher course. So that’s three days instead of four However, um, because I don’t climb constantly, like often it will be six months or more in between climbs, I’ll just do it before I know that I’ve got a climb.
all the other people except for one were technicians who, you know, have been working for a while.
So they’re also doing the full course, not the refresher. So they get a little bit more practice than I do. But, um, it’s just not often enough. Y-you know, like every time I go it’s like I, I really feel the need to have the refresher, um, because I’m just not fully on top of it. ‘Cause it’s [00:02:00] not just that you need to know what to do. You need to be able to… Like if you need to use it, you’re gonna be freaking out, you know?
This is the worst thing that’s probably ever happened in your life, and now you’ve gotta remember all your training. It’s like you want it to be actually second nature to some extent. So yeah, first day is manual handling, which is v- you know, very– That one’s very easy and I would be happy to never do that again.
Like I will always remember that. Um, then you got fire, um, fire safety awareness, and that one’s just fun ’cause you just get to, um, light fires and put stuff out then first aid, which I definitely always want a refresher on.
The CPR dummies at this place, they had lights, um, and it lit up green if you were doing it right, and I haven’t used a dummy that was so advanced before, so that was quite good. I realized I wasn’t pressing hard enough. and then yeah, last two days is working at heights training, which is the most intense ’cause you got your harness on all day and, um, you know, climbing up and down and rescuing people.
this was Rite Training in Goulburn, and, um, the [00:03:00] instructor’s name was Claire. highly recommend doing that one.
Allen Hall 2025: Is that a general requirement in Australia that you have GWO before you can climb?
Rosemary1: Like, yeah, they will sometimes, um, let you climb if you are babysat by people. I would not recommend other engineers, like if you’ve never climbed a wind turbine before, like I would really not recommend that you just go up with a team and haven’t done the training because you do need to be able to use a ladder safely and, um, you can, y- you can easily, like even inside the nacelle, you could easily hurt yourself really badly if you’re used to working in an office, uh, you’re upping your danger level by, you know, like many, many, many times by going up a turbine and it’s just something that you gotta take seriously.
Allen Hall 2025: How busy are the courses in Australia? Are a lot of technicians trying to get in and get trained?
Rosemary1: No, it’s people that have a job that are getting trained. But there were heaps of techs in this course. There were maybe eight or so, which is also part of the reason why it took a really long time.
Allen Hall 2025: So [00:04:00] this week, as we record, y- you’re presenting a blade repair course for engineers and technicians. a completely new area that you’re, uh, going into in terms of offering advice and expertise that it’s really hard to find on the planet. It’s probably a, a, a busy or, or requested course, I would imagine, in Australia, where you just don’t have access to a lot of the manufacturers.
Rosemary2: it’s a, it’s a course for just for engineers or technical type people, um, but including hands-on stuff. So the way that I I forced this to come into being was just the last five years. I, um, you know, I started working a lot on wind turbine blade repairs and, um, people would ask me, you know, “Have these repairs been done right?”
And the thing is that the only repairs that I had anything to do with when I was working at LM were weirdo ones, right? [00:05:00] Where the normal, like a technician couldn’t, couldn’t handle it. It was outside of, um, yeah, their, their standard, uh, kind of repairs that they can do for whatever reason. and now in the work that we do at Part Load, it’s primarily normal repairs, and I just didn’t know exactly what technicians know. You know, how do they, how do they know whether they can repair it or not? What do they know before they go up there?
When are they calling the engineer? Um, all that sort of stuff, like the normal stuff. eventually it became less about me learning, ’cause like I said, I kind of picked up most of it. Um, but now I’ve got staff that I’m training up to be, uh, you know, composites engineers and to work with these kinds of issues. There’s a lot of repetitive tasks involved in what we do when we, like, assess the condition of a wind farm.
A lot of what we do is look main- manually looking through photos and thing- if things are classified right or not. I [00:06:00] Found this guy from Direct Wind Services, Jurij Eska. He’s a blade engineer. He’s worked in Europe and then come back to Australia, so a little bit like me. And, um, I just worked with him on a few projects and I’m like, “Oh, okay. Well, this guy, uh, he really gets it.” And I asked him, “How do you, how do you train your technicians?
What course do they do? Maybe I can do that course.” And he said, “Oh, we train them ourselves.” And so then I asked him to put this course together. So where we started off the course yesterday, that was, um, uh, an indoor session where I was talking through how are blades designed, uh, certified, tested, manufactured, um, what kinds of manufacturing defects can you see and what do they do about them in the factory?
‘Cause you know that they’re doing a lot of repairs in the factory already before you ever see a, a brand new blade. and then the next three days we’re going to be working on, um, yeah, grinding and [00:07:00] infusions and a bit of a, a bit of theory about, um, composite repairs.
Allen Hall 2025: What do you feel like are those key skill sets that engineers should know how to do, maybe not as well as a, a professional technician that does it a lot, but at least at a beginner’s level should be able to complete them before they start repairing blades on their own and giving advice about how to repair blades?
What, what are those key items?
Rosemary2: part of it is that I want them to be able to understand what is a bad damage and what’s not a bad damage cause you look a lot at images from the outside, but it’s really about what’s on the inside and how deep it goes is the real thing.
So, um, it’ll be about learning, you know, developing some judgment about, um, how bad it can be and how bad it can look on the outside. We’re not gonna be looking at so many real damages ’cause like obviously we’re just dealing with pieces that are in the, um, in the, uh, workshop and Yuri has [00:08:00] made some samples for us, um, purposely made them badly so that we’ve got some, you know, damage to find.
Allen Hall 2025: Are you addressing carbon fiber at all?
Rosemary2: Uh, I actually haven’t asked about that. I don’t think so. Carbon fiber is, um, is a real pain to work with because it’s conductive. Like, even grinding it makes a bit of a hazardous work environment. We did talk a little bit about the different materials yesterday and, um, about pultrusions. And actually, it turns out Yuri used to work somewhere where they, uh, manufactured pultrusions, and I had always, I was always under the impression that a pultrusion is, you know, like, perfectly s- perfectly straight.
That’s the point. And he’s like, “No way.” No way. There’s waviness in the pultrusions
Allen Hall 2025: And on March 3rd through 5th at WOMA 2027, Rosie, you’re gonna give part of this course as part of WOMA, right?
Rosemary2: Little, little mini course. We’ll have to decide what, what makes sense to include, ’cause it was… Yeah, I went through really a, a fair [00:09:00]bit about blades yesterday, you know, like why they are shaped the way that they are. So we had to talk about aerodynamics and, um, why they’re made of composite. So we had to talk about, you know, like composite materials, like how, how they, how they work So I don’t know if, uh, people wanna write in comments that m- we should, we should do some sort of, um, poll beforehand to see what are the topics that are most interesting to people, ’cause I think we’ll have a half day, right? So we’ll need to be, we’ll need to be focused.
Allen Hall 2025: the description of repairs and what repairs should look like could be tremendously valuable. Everybody who has seen a repair always wonders, “Was that repair done right?” And s- and if you can have some general tools to know, like, “Uh, maybe there’s something not quite right here,” or, “That looks like a solid repair,” that would be a tremendous help to the industry, p- particularly for asset managers
Rosemary2: Yeah. And you know what I think is even more useful than being able to pick out when it’s wrong is to be able to know when it’s right. You can– Y-you know, like it is so– [00:10:00] It’s such a relief. Like it takes such a mental load off you when you’re just like, “Yeah, that’s all, that’s all good. That’s normal. Okay, I know that that– I knew that that would happen, so this is not a surprise.”
‘ know, once you know you can make that judgment, you can do it very quickly and focus your attention where it should be, so you don’t need to stress for an hour over every repair. You’re just like, “Yeah. Good, good, good, good, good.” And then, “Mm, please explain why you have chosen to not, not repair this, but just put a Band-Aid over it.”
that’s the goal of this training is to get everybody, y-you know, technical people, not people who wanna ever be a blade repair technician. They’ve got their own training that covers what they need to know. But this one is just, yeah, getting people like asset managers or my employees to learn what they need to know about composites, given that they have already got a strong engineering education.
So, um, you know, they know a lot of the stuff, but just need to know the composite-specific stuff and wind turbine blade-specific stuff
I will run this course again, by the [00:11:00] way, ’cause there was a lot of people who wanted to do it I couldn’t fit in. So it’ll happen at least once. I’ll keep on running it until everybody that wants to do it has, has done it. But, um, yeah, feel free
to get in touch

Allen Hall 2025: [00:12:00] Well, over in Canada, they just approved a, really a wind farm big enough to power a small city, and almost none of the electricity is going to the grid, which is a very interesting aspect to some of the things that are happening in Canada at the minute.
So up in Nova Scotia, uh, they’ve conditionally approved the Ocean Lake Wind Project. This’d be the largest wind farm in the province’s history. Up to 158 turbines will rise, uh, generating as much as 1.2 gigawatts of power. But this power is not headed to households in Canada. Nearly all of it will be feeding Everwind Fuels’ green hydrogen and ammonia plant at Point Tupper, where clean electrons will become a fuel that can be shipped across the ocean to Europe. And Matthew, there’s been a lot of [00:13:00] projects like this in Europe that have stopped more recently, particularly in northern Europe and up in Scandinavia, uh, on the hydrogen side. Or at least they’ve slowed them down. Canada seems to be going into that breach maybe to fill that void. And is there a marketplace for this to occur up in Canada?
Matthew Stead: Yeah, I think it’s very interesting. Um, you know, like you say, a number of canceled projects, and in Australia there’s been numerous canceled projects. So I like, um, the analogy or use of the term hopium rather than hydrogen, um, where, um, everyone’s hoping hydrogen will be the answer. Um, although, you know, what I, what I’ve read and understood is that, um, you know, the commercials just don’t really stack up and, um, yeah. So in terms of South Australia anyway, um, there was some major, um, hydrogen, uh, development planned with, um, you know, it, it never stacked up. So, you know, it sounds like a great [00:14:00] idea, um, but I’m not sure that the commercials will ever stack up unless you’ve got that guaranteed offtake for the, for the ammonium
Allen Hall 2025: Yolanda, what kind of uphill battle is this to get this wind farm up and running knowing that it’s one customer and that commercial market is a little shaky at the minute?
Yolanda Padron: what we saw, they have a lot of ca- caveats, right? So they’ve, they need to secure the customers before they start building and before they do anything, um, behind the meter. But it’s, I mean, it’s, it’s a pretty big wind farm, and it’s pretty far up north. But I mean, we, we talked to someone in, in northern US today who was having icing issues.
So I mean, of course we know Canada is no, no stranger to that, if they do make it work, I think it’d be really, really exciting to, to have sort of one technology power another, um, instead of just what we’ve been hearing a lot of the potential data centers and, and just wind po- [00:15:00] powering data centers.
Matthew Stead: Why not data centers? You know, seriously, like you said, Yolanda. why not go something that does have commercial demand?
Yolanda Padron: we’ve talked a lot about the potential of da- data centers, right? And we’ve talked a lot about people wanting to do them. Um, but there’s also a lot of talk of potentially doing data centers up in space and a lot of talk of maybe what if we do it offshore or, you know. And so I think there’s a lot of what ifs with data centers.
Of course, there’s a lot of what if with this, but just from a technology standpoint, I think this is really intriguing to have something that’s, that’s a little bit even more out there than what we’ve heard so far
Allen Hall 2025: Is it a build it and they will come type of s- situation here that hydrogen and ammonia may be the, the first offtake, but realistically, if that doesn’t work out, they can still connect to the grid and feed Canada, feed the Northeast of the United States or something else
Matthew Stead: Also, um, like Japan has [00:16:00] also expressed strong demand for, um, ammonia, and so, you know, they- they’re on the East Coast, aren’t they? So, you know, shipping it from East Coast to Japan is not gonna be so, so easy. I stick by what I said before. It’s hopium. it’s not a plan
Allen Hall 2025: I just saw an article today talking about Airbus continuing on with a hydrogen aircraft, and I think they were gonna work with a Japanese firm to work on that together. Six months ago I thought that died, but maybe it’s still in the offering. Maybe there’s an offtake for hydrogen. B- besides the, you know, replacement for some of the, uh, more unpleasant gases that are used in steel production and in some other industry things, maybe part of this is airplane fuel.
Which ammonia is one of those offerings also, right? The, there’s been a number of efforts to turn ammonia fuel into essentially jet fuel. They configure the engines to burn ammonia, which is a possibility. It does seem remote though, [00:17:00] honestly. There doesn’t seem to be a huge pull for hydrogen, and there’s not a, a major market for ammonia at at least at the moment.
So I don’t know. It, it’s… When you’re talking about gigawatts of capacity you’re gonna build, you, you hopefully have an offtake
for it
Yolanda Padron: if they designed it for it being not connected to the grid, right, it just is kind of like a behind the meter thing, and then could they later retrofit it into there? Like, how would all that permitting and everything
Allen Hall 2025: I–
well, that’s a great question. I– There are a number of, uh, connections between the United States and Canada at the moment. guess is that when they place this wind farm, they have that alternate route lined up, just like any wind farm in here in the States, that you’ll find them real close to high-voltage transmission lines.
Generally, those are the easy ones because transmission lines cost money and take time for permitting. I’m not sure Canada has those kind of restrictions, right? But Nova Scotia is not the easiest place in the world to do heavy construction work, just the [00:18:00] nature of Nova Scotia. It will be fascinating to see how they progress with this, but it’s something to keep an eye on because a lot of other projects like this have slowed down
Matthew Stead: Do you remember when some of the OEMs were talking about, um, putting electrolyzers on their offshore wind turbines? So the, the theory, the theory was you’ve got offshore wind turbine, you don’t connect it to the grid standalone, um, and you generate hydrogen or, uh, possibly ammonia on the actual wind turbine.
And then every now and then you just decant it, you know, drive up with a boat, you know, plug in the hose, and then suck out the hydrogen or ammonia. So, um, yeah, once again, all of those have gone quiet, haven’t
they?
Allen Hall 2025: speaking of Japan, a global oil giant is walking away from the Japanese offshore wind project, uh, but the project’s not dying. BP has told its Japanese partners it intends to withdraw from a wind farm planned off Yamagata Prefecture, uh, apparently worried about [00:19:00] profitability. The 450-megawatt project sits, uh, just off the coast, and it is led by trading house Marubeni, which says it will press ahead without BP.
Kansai Electric and Tokyo Gas remain on board also. So BP’s exit follows really a, a brutal year for Japan, where Mitsubishi has, and some others, have pulled out of, uh, at least three projects so far, uh, over rising construction costs, and I think a lot of that’s tied to inflation. Uh, the ambition’s still there for, uh, for a number of companies, but it’s just getting harder and harder to do projects in Japan.
Is this just the nature of the economy in Japan at the moment, or is this more about Japanese policy on the offtake,
Matthew Stead: I, I’m not really deep into the details but, you know, it just appears to me like a blip. I mean, there, I think there’s a lot of commitment in Japan to, you know, carry [00:20:00] out their offshore developments and I, I think this is probably more just a blip, um, and a little, you know, internal corporate, you know, argument rather than a sustained issue on offtake agreements and so forth
Allen Hall 2025: Well, Yolanda, how hard is it to keep partners on a wind development in general? Are there a lot of moving pieces there until the turbines hit the water or hit the
earth?
there’s
Yolanda Padron: I think a lot of moving pieces, but not, uh, I haven’t seen a lot of changes once it’s been publicly announced and everything’s, you know, everything’s been signed and everything. Um, I do think this is really interesting. I know we’ve talked a lot about, about having, about the idea of like sometimes people think wind’s really expensive, and the way that we’re gonna make wind work is just making it cheaper for everybody and just optimizing it as much as possible, um, and, and just being, having the turbines be as resilient as possible, right?
And I think such a strong player just backing out maybe [00:21:00] will incentivize some of the people in Japan to sort of try to see how they can optimize it a little bit more. I’m really excited to see it. I don’t know. It’d be… I think it’d be a nice it
Allen Hall 2025: Isn’t the bonus to offshore wind the price stability? Although the price may be higher today than you may be happy to pay, the stability of that price is a huge leverage point when you compare it to things like oil and gas or natural gas, um, in particular, which are highly volatile, that for electricity, at least you have this fairly steady source at a fixed price that you can plan out 10 years, 20 years, 25 years, maybe even 30 years. And as batteries become more prevalent on the grid, that the math even gets better over the years. Isn’t that the bonus? And, and if [00:22:00] everybody can focus on the long-term effects to the economy is where all the action will be?
Matthew Stead: Yeah, I mean, when I first, um, started looking into wind, you know, 10 plus years ago, I, I won- wondered why. Why would you build offshore with all that expense? And then, you know, it became clear to me just around the, um, you know, the diversity, you know, the, the fact that you might get more wind at times that you don’t get onshore wind, and the fact that it’s more consistent.
Um, yeah, and, you know, so those… I- it’s really a trade-off, isn’t it? Between the capital costs and the, um, more reliable, more consistent, um, offshore wind. So I think, you know, I, I was convinced at the start, I thought it was crazy, but then obviously it’s, it’s a, it’s a… it makes sense
Yolanda Padron: Yeah, I agree. And I think, uh, depending on where you’re having your offshore wind farm, you run into things that you maybe haven’t run into before, right? I know onshore we run into a lot of things in the [00:23:00]US and Australia that we, you know, the, the turbines just maybe weren’t designed for, or there wasn’t a lot of research being done because it was being done in Europe and, and the conditions are really different.
Um, and just the same way, you know, the sea is different in different places. There’s different depths. There are diff- different things that you need to worry about. but yeah, I, I completely agree that there’s a lot more generation, um, offshore. It’s, it’s bigger turbines. Um, there can be bigger, larger costs. You know, if you need to do a blade replacement or something, it, it can get, again, really expensive really quickly. But, but it’s, it’s a trade-off for sure.
Allen Hall 2025: We’re gonna take a quick break, but when we come back, we wanna talk about a place where wind is being fought over versus projects slowing down
[00:24:00] over in the UK, there’s a big fight about offshore wind, and not just about where wind turbines will be planted, but more about how they will affect other wind turbines.
So RWE is defending the UK government’s approval of its three-gigawatt Dogger Bank South project, which won its consent order, uh, basically a month and a half ago. Uh, but the developers next door are taking that approval to court. Equinor, SSE, Vårgrön own the neighboring 3.6-gigawatt Dogger Bank wind farm, and they have filed for j-judicial review.
Their argument is technical, but the price tag is not. They say wake effects, where one wind farm steals the wind from another due to turbulence, could cut their output and cost them between €500 million and [00:25:00] €669 million over the life of their project. That’s a lot of money, Matthew. A half a million euros is not something to ignore.
It looks like this is headed to some judicial court or maybe arbitration. Wake effects, which are actually not that well understood from what I can tell at the moment, there’s a lot of discussion and argument about, uh, how real are they or, or what effect they can have on power output. Uh, there’s a lot of money at stake, and the location of some of these wind farms is pretty close to one
another
Matthew Stead: you know, we always, always talk about, you know, AEP loss and, you know, the, the challenge is actually measuring it. And, um, you know, I’ve heard different numbers, but, you know, plus or minus half a percent of AEP loss, um, appears to me from what– in discussions, you know, the, the limit of what you can actually ever measure on a good day.
Um, I just wonder, I mean, while those numbers, you know, €500, um, [00:26:00] million is a, is a big number, um, but what is that as a percentage of the overall output of that, of that facility? Um, I, I don’t know the answer, but, you know, if, if it’s, you know, half a percent, I think you’d be struggling to, um, struggling to justify that, that wake effect loss.
I mean, you know, going back to what you said, Allen, you know, there are wake effects of some sort, but it’s a question of how much. I mean, that-that’s why aircraft don’t take off, um, too closely, isn’t it? Because there’s wake effects. Um, so it’s definitely a given, definitely a given. Um, but, you know, how much of an impact it truly is.
Um, and I mean, there’s always other variables, you know, variables in the weather, you know, wind patterns, da, da, da, da, da, da, da, and how much do this– does this actually compare to those other, other variables?
Allen Hall 2025: Yolanda, how would you even mitigate wake turbulence on an adjacent wind farm? Are there ways to do that today?
Yolanda Padron: I think the, the aerodynamics, Allen, would [00:27:00] be a lot more in your court than, than in mine.
Matthew does have a really good point. I mean, what are we… With the UK wanting to ramp up offshore as much as they want to ramp up, right? They’re not going to just cancel a large project, and they need to… I mean, it’s not, uh, there’s a finite amount of space, right? So what, I mean, what, what are you, what are you gonna do?
It’s like, it’s what, like, what happens in onshore where you, you really hope maybe that you don’t get a wind farm that’s really, really close by. Um, but you might also want to plan for it. I mean, I know of sites that have le- that lease a little bit of extra land so that way no one else can lease it, or that they can, they can use that to, to travel between turbines.
Um, and it’s, I mean, it’s, it’s kind of… Isn’t it kind of just part of it, part of the trade?
Allen Hall 2025: it has to be, right, at some point. [00:28:00] The question in my mind about all this is how much wake is there? Is it directly impacting the adjacent wind farm? Is there– are there things that can be done to minimize that wake turbulence? I think the answer is yes, but as wind turbine blade designers, I haven’t seen the same level of wake reduction that we have seen more recently in aerospace.
It’s complicated to do some of these things on a wind turbine blade. You’re mass-producing. You’re making a blade a day or a blade in a day-and-a-half timeframe. Are you gonna design this really aerodynamic tip to go on to reduce the wake on a particular wind farm? Probably not, right? So it’s, it’s– is it worth doing that versus the, the cost it would be?
So it’s gonna cost 500 million euros in loss to an adjacent wind farm. Do you put that 500 million into the design effort and the molds and [00:29:00]everything else to make these blades different? Uh, it’s a tight trade-off, right? It– from the engineering side. It may be better settled in the courts, honestly. Just it may be cheaper to do it that way.
Matthew Stead: Uh, I, I was gonna go down a different avenue. I mean, obviously there’s always curtailment. There’s always curtailment due to grid congestion, et cetera, et cetera, et cetera, maintenance. I mean, if they, if they just– when wind is coming from a certain direction, they could just de-rate and, uh, just not absorb as much energy, um, out of the wind when the wind is coming from that sector.
And so that would be a way of, um, not modifying the turbine, just de-rating it under a certain wind condition. I mean, the same thing occurs with noise curtailment all the time. Um, so there’s, there’s noise modes. There could be a, a wake loss mode. We should trademark that
Allen Hall 2025: Well, you know who’s gonna make money out of this no matter what? The
lawyers.
Allen Hall 2025: [00:30:00] Well, in this quarter’s PES Wind magazine, there are a number of great articles, and you can download the entire magazine and all those great articles at peswind.com. There’s a nice little article from Enerpac Tool Group, and if you’re not familiar with them, they make a, a number of tools that are handy in the wind industry.
Uh, and, you know, routine torque checks is kind of a pain, right? And the problem with a lot of those checks is that you have to haul around a heavy hydraulic pump to do it. And so if you’ve ever been to a trade show and seen some of these [00:31:00] pumps, it is a pain. And if you h- have to move around, especially on a w- wind site a lot, you really don’t wanna have a heavy pump that maybe is made for something, uh, more robust.
Uh, and you need something that’s portable. That’s what you really need, right? So the Enerpac Tool Group has really created this, uh, LU series they call. Which is a lightweight, portable, hydraulic pump, which is for intermittent work, which is what happens on most wind sites. It’s intermittent. Uh, so the product line director, Angie Wallace, uh, talks about this and says technician feedback has shaped this new tool, uh, from multiple carrying handles and an upward-facing gauge.
And that is a big thumbs up from me. When you put the gauge on the side of the tool where you can’t see it, such a problem. It’s like they’ve never used it. Well, obviously, the Enerpac has been talking to technicians, and they put the gauge where the technician can actually see it. Uh, and it’s designed to go through towers and, and tight [00:32:00] spaces.
Uh, so this is made specifically for offshore conditions. It’s ruggedized, and it’s a great tool. And a lot of times, Matthew, when you s- see the technicians about and some of the tools they carry, you’re like, man, that is not a good tool for this. That is, that is too much to be hauling around, particularly uptower.
It’s nice that we can see some tools that are designed job
Matthew Stead: I, I’m completely convinced. I, I don’t have much to say. Um, I mean, my, my day job is, um, you know, designing products and working out what products we’re going to, to work on, and, you know, the customer is the main voice you should listen to, um, at least in the first step. So always listen to the customer first, and I think from what you’ve described, customer first, and then develop the product to suit the application.
Yeah, so yeah, I’m convinced
Allen Hall 2025: Yolanda, you’ve seen Interpack on sites, haven’t you? It does seem like I run across them once in a while at some of the US
sites
Yolanda Padron: Every once [00:33:00] in a while. I do gotta say I love the idea of when, like, actual, like, boots on the ground people’s feedback is taken into consideration for, for anything really. And so this is, this just makes me really happy because I think a lot of times, like, as engineers, like, we love the idea of just, oh, I’m gonna do this really cool fancy thing, and then it’s just it- no one can use it, or a very specialized person has to be able to use it.
And so actually doing, you know, modifying a product so that it, it makes sense for the people using it, and I know we’ve, we’ve all talked about it a lot internally and, and we continue to work towards making it easier and easier on, on the people actually installing the product. Like, this is, this is really exciting.
Allen Hall 2025: So if you need a lightweight pump for tightening some bolts uptower, particularly if you’re offshore, take a look at this Enerpac line of LU lightweight series tools. It’s well worth it. And at that same time, you should check out PES Wind magazine. Just go to [00:34:00] peswind.com
