Wind Farm operators face mounting challenges from managing thousands of diverse turbines to navigating the energy markets and constant regulatory changes. This week we speak with Alejandro Cabrera Munoz, CEO, and founder of Green Eagle Solutions. Green Eagle’s ARSOS platform gives control rooms immediate responses to turbine issues, which dramatically increases productivity and captures more revenue from their turbines.
Welcome to Uptime Spotlight, shining Light on Wind. Energy’s brightest innovators. This is the progress powering tomorrow.
Allen Hall: Alejandro, welcome to the show.
Speaker 3: Thank you, Allen. Thank you for having me here today.
Allen Hall: so Green Eagle Solutions is in a unique space of the renewable energy marketplace, and you saw a problem several years ago, particularly in the control rooms of [00:01:00] wind operators. What is that problem that you identified?
Speaker 3: Yeah, Allen, I think it, it’s, It’s a challenge that, most of our customers, which are generally large operators, are facing today. But it’s a challenge that have been, growing, in the past years. So first of all, it’s, it goes along with the penetration of renewables in the industry, right?
So we have, due to all these many years of aggregating new wind farms and solar plants, We are seeing how the complexity, the technical complexity of operating and supervising these assets is growing exponentially, right? So we now have customers with thousands of wind turbines that have, different models, different versions of, controllers, And also different healthcare issues that they have to take care of. So the technical complexity is a fair, the first [00:02:00] factor that, it’s has to be tackled from a control room, And, makes, operations quite, challenging. Along with this, we have market volatility. So in the recent years especially, we are seeing how, Negative pricing and optional markets are now affecting operations in a daily, basis. Basically in every 15 minutes you dunno if you’re gonna produce or not. Up until recently it was as simple as if you had wind resource, you would produce energy from wind farms. If you had solar, you produce energy from solar plants.
It’s not like that anymore. So the market is quite, volatile. that adds a lot of complexity from the commercial point of view of, Of the assets. And the last, factor that is actually becoming, an increasing challenge for everyone is the regulatory changes. So basically due to the penetration of renewable energies, what we see is that all governments, all grid operators and our market operators are constantly issuing [00:03:00] new adapt, new regulatory changes, that everyone has to adapt to no matter what.
it doesn’t matter if you have an all wind farm or a newer wind farm. Or you prepared or not, like everyone has to be adapted to, to the new regulatory, changes. the three things are actually affecting, our customers and we are trying to solve all these issues, the way, the, best way that we can, right?
So most of our customers, we just have a control room full of people. they will do their best effort to accommodate these challenges. The reality is that we have to. Deal with, people, procedures, and, systems, and we, if we don’t put these three things in place, it’s impossible to cope up. With the complexity that we are dealing with, and that’s where we come in.
Joel Saxum: I think you painted the picture of a really good problem that’s not just like local to the eu, local to India, local to South America, whatever. it’s a global issue, right? You have the, massive build out of different kinds of [00:04:00] technologies that need to be managed in different ways that, bring their own issues, their own delivery to the grid, those kind of things.
and then you, and as Green Eagle has, painted the picture like, Hey, we saw these issues. This is where we come in, this is where we step in. So in that, what kind of inefficiencies are you seeing in the traditional wind farm operations versus what you guys are bringing to the table now?
Speaker 3: So just to give a few examples, and I think I, I can be quite, precise on this. let’s say that a wind turbine gets some fault because of, high temperature on the gearbox, and it’s a. It’s an automated response from the manufacturer that the ban is gonna stop for safety measures, right?
So in many cases. This is solved from the control room point. from the control room by waiting for an operator to just, follow a procedure, right? So this procedure takes a lot of time. Why? Because you are not only paying attention to one winter turbine band, you may have 2000 winter turbines, right?
[00:05:00] So you have to first identify, which is a model of winter turbine band that is affected by this issue. Then you have to go through the manual, then you have to check what are the parameters, and the whole process takes minimum half an hour if you wanna do it properly. The problem is when you have other issues like high wind speed, right?
So normally when you have high wind resource, which is basically when you can produce more energy, is when your assets suffer the most. And so they’re more prone to errors, they’re more prone to go get on fault. So if you take a look at these times, the country room, response time is actually gonna go up in hours, right?
So this one of the one simple example is a end-to-end full haling procedure that takes between. 20 minutes, two hours, depending on how you have a structure, your systems, people, and procedures, right? So this is the first thing that we can tackle. Like just as an example with our software, we can automate the whole process end to end.
That means that this problem is never gonna be dealt with. From an operator, This is gonna be [00:06:00] automated. This is an, this is never gonna become an issue for an operator ever again.
Allen Hall: Yeah. And I think this lends itself to software obviously, that there’s, if you look at these control rooms, if you, or especially if you looked 3, 4, 5 years ago.
It’s pretty chaotic in there. And if you are on the market for electricity and the price is fluctuating and you have turbines popping on and off, you have a crisis and it’s very hard to sort that out and to get the turbines up and running if you need them to be, to produce power so you can make money.
’cause ultimately we’re trying to maximize the revenue to our company. And that cannot be a human response. We’re too slow. Humans are too slow to respond to all this. And because we’d have to know every nuance to every turbine or solar farm makes the problem immensely impossible. So that’s where you have developed a piece of software called.
ARSOS and it’s a system approach to a very complicated problem. So you want to explain what ARSOS does
Speaker 3: [00:07:00] effectively, what, what ARSOS does is to provide immediate response to whatever issue you have already a procedure to deal with, right? So let’s take into account the, previous example that, that we were using, in this case.
And, there are hundreds of different cases where a wind turbine is gonna stop. Every wind turbine is gonna, can have potentially hundreds of different. Scenarios where it’s gonna go on fault and require human attention or attention from remote. So the first thing that we can, provide is, immediate response time.
I think all the investment funds, IPPs or utilities, can now rely on a system instead of, relying on people. They can rely on a system that is gonna do effectively. The first phase actually is gonna do exactly the same. With immediate response time, this is what our source is all about. according to our experience, we have identified if you, could take 100% of the issues or incidents that can impact, the availability of the assets.
We have identified that at least [00:08:00] 80% of those incidents can be managed autonomously. Among that 80%, almost 75% of them can be resolved autonomously, and the other 20%. It can be just dispatched to, technicians on site so they can actually go on the turbine and fix the issue on site. So this, this is, this is our goal.
We can multiply by five the operational capacity of our customers. but along with that comes many other benefits. So the, main one, we already tackling that, right? So immediate response time with that comes, increase of productivity because we don’t need operators to be doing repetitive tasks anymore, so they can actually do other.
Added value activities, but immediate response also provide with an increase of availability, which also translate into an increase of production and again, translate into additional revenue. So effectively what we’re doing is to transform a traditionally thought of, center of cost, like the, it is a [00:09:00] control room.
We can optimize the control room to a point where it’s no longer a center of cost. Actually an opportunity to turn that into a center of revenue. We can actually improve the operations. We can actually capture more revenue from our assets. But we can only do that through automation.
Joel Saxum: So when you’re talking with operators, okay, so I’m, right now I’m imagining Alejandro on a sales call and you’re talking with them and you have, you may have in that room, some energy traders.
You may have some of the operators from the ROC, you may have. an engineer in charge of it, an asset manager, someone of that sort, and you start talking through the problems that you guys can solve. Which ones make the light bulb go on the most? Is it the revenue? Is it like, Hey, we can actually pull more revenue outta here, or is it, Hey, operators of the control room, we’re going to ease your life.
Which, which of these are the breaking points that make people go, yes, we want to use Green Eagle?
Speaker 3: Yeah, that’s a great question, Joel, and unfortunately it’s not that simple to answer. I wish I had the, right answer to that. [00:10:00] But the reality is that every type of customer has different, interest.
and I’m gonna give you a few examples. if you’re a trader, what you’re gonna value is the capabilities to participate in advanced, optional markets, right? Especially in Spain, we are the most used, technology to participate in secondary markets and c services, restoration reserves and so on.
So we enable our customers, the traders in this case, to participate in all these markets with zero efforts so they can focus on trading. But all the infrastructure, all the communications, all the actual management of curtailments is done automatically. So they can just focus on trading. but that’s what they, see, right?
If we were talking to an IP for instance, ISPs are generally, focused on or driven by, service level agreement based on availability, right? So if they say, if they, if their commitment is 97% of availability, they’re [00:11:00] gonna try to reach that, right? So that driven by the availability. but that’s it. they’re not necessarily capturing more if the availability goes higher than 97% or if the site is being operated better, or if the site is being actually producing more.
Sometimes they’re not incentivized by that. This is why, the reason, this is the reason why we are not normally focused on large utilities and large operators because, effectively, large utilities and IPPs, they, if they’re large enough, they’re gonna have everything in house. So they’re gonna see the benefits at all levels.
They’re gonna increase the productivity, and they’re gonna improve their operational model as a whole. So that’s why, we are targeting, these larger operators.
Allen Hall: I know a lot of the different operators have their own models of how to respond to particular alarms. Everybody does it differently depending upon a lot of it’s where you are in the world, where your wind turbines are and how your wind turbines respond to certain conditions.
So they’ve [00:12:00] developed these sort of procedures themselves. Are they able to integrate their existing procedures into the ARSOS platform where. Basically they’re taking the human outta the loop, but just automating it, making it simpler for the control room to run these turbines.
Speaker 3: That’s a great question, Allen.
of course, yes. and this is something that, we’ve been, seeing from day one. at the beginning when we thought, let’s, automate all these processes and all these procedures, I, we thought that we were gonna find like a common ground of how to deal with this model of turbines. However, what we see is a complete different way to.
To operate a fleet. And it depends on both commercial, and operational strategies. for instance, a utility that is gonna keep their assets for 20 years, they’re gonna have be paying attention of what is the most effective way to operate, taking care of the healthcare, of the assets. So it’s gonna be more conservative, it’s gonna be more long-term thinking.[00:13:00]
on the contrary, if, let’s say that you have a portfolio that you’re gonna sell in two years. That may drive, you to a more aggressive protocol. So you may want to, hire the higher the availability, increase the production, even if that comes at a cost of, a little bit more fatigue on the winter turbines.
So it all depends on how, what you wanna get for your fleet. what’s important is that we allow, we provide the technology. We don’t tell our customers how to operate. Actually, they have. They have more knowledge than us, to be honest. They know their assets, they know how they behave, and if you ask them, they know exactly that Tar van, three out of 2000 in this wind farm has this issue, and the other one that has a different issue, they already know that stuff.
So we’re not gonna tell them how to operate their fleet, but we allow them to do whatever they think is best for turbine. By turbine, I mean with our software, you can actually define different protocols and assign each protocol to one turbine. That means that, for instance, [00:14:00] if you, change the, the gearbox of one tarn out of 2000, right?
Normally you, what you would like to do is that the next day everyone is paying attention to the tarn in case something happens, right? but you have 2000, so that’s actually not very realistic. So in that case, what you do is that you configure out protocol that is designed for that specific model of turbine, and that takes into account that the gearbox was replaced recently.
So if there’s an alert, on a fault related to a gearbox. Then the response is gonna be taking that, it’s gonna take that into account. So obviously this kind of things can only be done if you’re based on, automation. Otherwise you just, have to rely on a few notebooks that you have in your control room and that they’re static.
They never change. they’re the same for 20 years and they never evolve.
Allen Hall: Yeah, they’re the same for every turbine. And that’s just a approach that we need to give up, that we need to move on as an industry to be more efficient in what we do. So how. [00:15:00] Does an operator, and I know you’re working with a lot of large operators and have a lot of turbines under your systems.
How does the RSOs implementation take place? What does that look like?
Speaker 3: All right, so it depends on the, I would say on the digital maturity of our customers. So it depends. Some of them already have a very strong network. Secure network. They have a, let’s, say, one of our customers in the, us, right?
So they already have a NERC department in place. basically what, first we need to understand what, they have already in place and how we can fit into that, solution in this, in the most, let’s say most, most demanding scenario. We are, gonna deploy your software on premises. So it depends on whatever they have already in place with the, we deploy your software, we provide them with the installers.
We provide them with the procedures and they are autonomous to, to install it. Obviously with our support, from remote [00:16:00] in, in other cases, in the other extreme, we have customers that don’t have a large portfolio. They don’t have these large IT and nerc. Department, in place. So in for smaller portfolios, we can actually connect from our cloud.
Our cloud, we make sure that it’s cyber security. We have all the certification in place. and this is the solution that we have. So we have, our cloud is connected to an onsite, piece of software that we install on, the edge, and they’re connecting securely. And that’s how we do it. in terms of architecture, I think it’s important, to get deeper into.
Why we are, proposing a, we are also establishing a different, way to do things because it also has to do with the architecture itself. if you take into account, the NERC rules in the US but also any cybersecurity policy, it is basically gonna go against any kind of [00:17:00] optimization, in the operations, right?
Because when you have so many issues, as we mentioned before. The tendency is gonna be to, okay, so this let’s centralize everything into one place where I can actually manage everything, efficiently, right? So one place centralize. I can control everything from this place. I have a control room here. I.
That’s it. Now that goes totally against cyber security policies, philosophy, right? Which they would like to have everything isolated from each other. So you have to actually go to the site and push the button right there. Now we have a, I would say the best solution, that covers this, both worlds, right?
So we have a solution that allows you to centralize the configuration. Distribute the autonomous control. That means that instead of relying on a centralized control room where the operators are pushing the button, so in the control room, you actually don’t push the buttons. You have the control room to supervise and to define the protocols itself.
Then these protocols are. Sign to each turbines, [00:18:00] the right protocols, but then the control is actually done autonomously on site. So even if your control room gets disconnected from the sites, from the network, you lose connectivity to your control room. You cannot access for whatever reason to your control room, you can be certain that your sites are still being operated in the same way.
If you could access your control room. So this is actually compliance with the cyber security policies at the same time that is allow, is providing you with what you were looking for to begin with, which is efficiency in operations.
Allen Hall: When an operator installs the RSO system, what are the typical things that they’ll see immediately?
is it just easier to operate the turbines, it just requires less staff? Are they producing more revenue? What are those success stories look like?
Speaker 3: Yeah, success stories look like this. Just like any automation attempt at the beginning, everyone is suffering from a little bit of, control, fism, right?
So it is okay, am I losing control of this? So we already have a system to deal with this. So what we do, basically, we install [00:19:00] our software in parallel to your control room. it works as a shadow mode, in a simulation mode. So basically what it does is to say, if this was active, what would it do?
Automatically versus what actually, what, are my operators actually doing? So we can actually compare for a few weeks or a few months, the performance of the automation versus the performance of the, current room. So normally when we propose this, customers, I will say in the mindset, it’s okay to test this for two, three months and then.
Go ahead and say, okay, let’s activate it. I no longer want to do this manually. It’s a waste of time and resources, right? The reality is that as soon as we put it in place and they see how it works, how it re respond immediately instead of. The delay that comes from operators, it takes, I would say, no more than two weeks until they’re already ready to put it, in production mode.
Allen Hall: When they see the lost revenue, [00:20:00] they would immediately turn it on and start making some more money.
Speaker 3: It takes between two weeks, no more than a month for sure.
Joel Saxum: I hear water cooler conversations. That would be like the ro the robot beats you guys again, you
Speaker 3: know. automation has a very interesting effect.
It’s that. I would say it’s a vicious cycle. So once you see something working autonomously, the brain works in a very interesting way. It’s you never want to do that manually again. It’s am I doing it? It doesn’t, it does not make any sense anymore. so it triggers, whole, efforts to just more of it, right?
More of it. It’s okay, if we’re doing a. POC with 10 sites, but you have 30 sites. You want it in the 30 sites as soon as possible. If you’re doing it to automate a few cases, but you know that you can actually automate more cases. You wanna do it as soon as possible as well. So it triggers, once you start this process, there’s no way back.
it triggers this vicious cycle where you are constantly thinking, okay, what’s the next thing [00:21:00] that if possible, I don’t wanna do it again. It’s very exciting.
Joel Saxum: I’m thinking about when I used to write reports in Excel and I learned, I finally learned how to do a macro in Excel, and then I was like, why I’m never writing another basic one of these reports again.
I could just push a button and it does it all. and it’s life changing, right? So once you get onto that, there’s just, there’s, people that are wired that way too, right? I used to have a, mentor that was wired. How can we do this better, faster, more efficiently? And it, he was trying to put that into everything we did.
Once he figured out a little way to do here, a little way to do here was, how can we make this better? so you guys have been working, really hard to get this system out through the Green Eagle ASO solution out in the marketplace. Based on the success you’re seeing, what does it look like for the future?
What’s the next step?
Speaker 3: So I think that the, in the future what we see, at least what we are aiming for is that every wind farm should have a system like ours. I don’t really care if it’s ours or not, but it should work that way. as a, [00:22:00] from a technical point of view, it’s it doesn’t make any sense that not all wind farms are running with a system like ours.
So that’s the way we see it. Like it’s, Getting momentum. I think it took a while for us to, take off and to get large customers to use our software, but now that large customers are using it, and the system is more than validated. We already have this running in over 10,000 wind turbine vans.
So I think it’s more than proven that it works and that we are solving a problem that no longer exists anymore. This is how we see it, the wind industry in the next, three to five years. All of the wind farms should come with this, and essentially we’re trying to make it come with a software like ours from day one.
So even if they’re already still connected to the manufacturer. It only, this can only benefit in the long run, right? but starting from day one. So this is what we are working on and how to get there as soon as possible we can encourage our customers to, [00:23:00] to start using this automation. To enable them to take back control of their assets to their operations, to not rely on someone else to do your, the operations of your site.
if you wanna get out of the manufacturer and work with an ISP, you can also make sure that the response time from their control room is also gonna be immediate with the software. So as soon as you have it, you’re gonna see the returns. And actually, we also work with our customers to. To prove the increase of revenue that they experience.
And we, the benefits of automation also is that you can measure the impact, right? So we generally work with our customers. We can measure the impact in their operations and we normally capture like a third of what they are gonna receive. So it’s like a no brainer to use our software. And for that reason, we believe that three to five years from now, every wind farm is gonna be running autonomously.
Allen Hall: Wow. That would be amazing. And the Green Eagle Solutions website, if you haven’t [00:24:00] visited it, you need to, it’s green eagle solutions.com. There’s a. Great information on that site. If you want to dive in deep or just take a cursory look, that’s the place to start. Alejandro, if they want to connect with you to learn more about ARSOS and what it does, how would they do that?
Speaker 3: the most, straightforward way to write an email to sales@greeneaglesolutions.com.
Allen Hall: That’s a good place to start. And you can also find Alejandro, LinkedIn also. Alejandro, thank you so much for being with us today. Tremendous product, very interesting technology. I. Thank you so much for having me today.

What Operators Want to Hear at WOMA 2027
Two days of operator meetings in Melbourne shape the WOMA 2027 agenda, from performance upgrades and cable faults to foundations and bolts.
The Uptime Wind Energy Podcast is brought to you by Weather Guard Lightning Tech, creators of the StrikeTape Ultra LPS retrofit. Subscribe to Uptime’s Substack newsletter. And check out Rosemary’s “Engineering with Rosie” Youtube channel. Have a question we can answer on the show? Email us!
Allen Hall: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Matthew Stead and Rosemary Barnes. And Rosemary, where are we?
Rosemary Barnes: We’re in Melbourne, and we have been visiting future attendees and sponsors and people interested in, in the event to see what topics that we should be talking about.
What are the hot topics of the moment?
Allen Hall: Which is a very interesting two days, Matthew, in that, uh, we h- did meet with a number of operators based in Australia, but, uh, they’re also very worldly. They have talked to companies all over about operations and, and maintenance, and there are some really eye-opening topics- Mm
that will be- Mm … at WOMA 2027 this year.
Matthew Stead: Yeah. The thing that was interesting for me was [00:01:00]that actually the topics have changed each year. So, um, they’re evolving and the industry’s continuing to, to do better, and so that, that was really interesting. Performance upgrades was probably one of the big areas of, of new interest, I think.
I think we heard with the pressure on pricing, uh, the market and so forth, you know, that, that 1% or 2% now is becoming more important. Um, so I think, uh, upgrades will definitely feature quite a lot. Um, balance of plant was also a big topic. Um, you just can’t ig- ignore the, um, transmission, you can’t ignore the transformers, you can’t ignore, uh, condensers and all these sorts of things, so yeah.
Rosemary Barnes: Cables.
Matthew Stead: Cables.
Rosemary Barnes: Terminations. Terminations of cables. Specifically raised several times.
Allen Hall: Yep. Yeah. It’s all about being more efficient, uh, getting more production, and then with the PPA prices, uh, that are changing-
Matthew Stead: Mm …
Allen Hall: rapidly, uh, everybody is paying more attention to the bottom line.
Matthew Stead: Mm, mm.
Allen Hall: Absolutely. There, there’s less cash running around, uh, chasing new development.
It’s [00:02:00] more of a focus on making sure your, at least your existing assets are performing as, as well as they can be- Mm … which then opens up the, uh, Pandora’s box of opportunity. Mm. Because there are 1%’s all around a wind turbine. More specifically, uh, all the drive train issues, the blade issues, the generator issues, and even going into the substation.
Mm. I, I was really shocked on BOP e- the, the one topic that came up, uh, yesterday and today was buried cables. Mm. Like-
Matthew Stead: Faults …
Allen Hall: faults.
Rosemary Barnes: Yeah. Junctions. Finding- Yeah … finding faults and what to do about them. Yeah. Yeah. But I think in addition to just wanting more revenue, I think people have, are getting more sophisticated about what actually matters and then the finances.
You know, everyone’s focused so much on availability, and now people- Mm … are like, okay, yeah, like once you’re at a certain level of availability, gets harder and harder to get more. And actually, you know, not all availability is equal. Is good. It, it [00:03:00] depends. Yeah. Yeah, like you wanna, um, you wanna focus on how much you’re generating at the times when electricity prices are high specifically, which usually means during lower wind speed periods.
Yeah. Which is actually good because that matches really well with what is actually possible. It’s, it’s hard to get more power out of the turbine if it’s at, you know, its rated power, then you’re not g- More efficiency is not gonna get you any more, um, power output, whereas lower in the power curve- Mm … um, when wind speeds are lower, there’s less electricity in the grid and so prices are higher.
And so- Mm … yeah, I mean, that’s, that’s why people are really asking to know more about what efficiency upgrades are possible, better ways to operate, scheduled maintenance, um, all those sorts of things. Mm. So that will be really interesting.
Matthew Stead: Raising the bar on sophistication. Um, but also life extension
Allen Hall: Yes, a lot of discussion about life extension
Rosemary Barnes: Yeah, end of life and life extension End of life Yeah, um-
Matthew Stead: Foundations, structures Which is
Allen Hall: tied to PPA.
Mm. A lot of that [00:04:00] discussion I, at least I looked at it as, uh, if I had a PPA and I can continue with that PPA with an existing turbine, I want to do that. Mm,
Matthew Stead: mm,
Allen Hall: mm. But how do I do that and how do I know that that existing turbine can last another five years? It seemed to go in five-year blocks, like can we get to another five years and then another and then, then another.
Wow.
Rosemary Barnes: Yeah. Once you get to 20, 20, 25 years, I think people like, uh, they, you know- It’s getting a little- Their original agreement might have been for 20, then they kind of just assume that there will be another five, and then after that they’re- Yeah … kind of reassessing cyclically and yeah, I know that people make plans for, you know, what components are replaceable, what would they have to get in, and I think that sometimes, uh, people doing those plans aren’t as familiar with the, you know, actual technical issues that are being faced.
Like, is a blade a replaceable component? It may be early on in the life it sort of is, not easily, but you know, like a 25-year-old wind turbine, you know, good luck trying to order 10 new blades because you’ve got a, you know, an issue that’s-
Allen Hall: Oh, well you, you need to read the news. Did you [00:05:00] see the news today about, uh, the, the wooden wind turbine blades as a replacement for aged blades?
That, that’s happening- … in real time, Rosa.
Rosemary Barnes: Okay. I know they- Yeah. Yep, yep. Okay. Okay. So that, that’s, that’s good. Making carbon new blade. E- even so, I don’t think that they’re- Okay. … gonna be, like, super-duper cheap, so you’re still gonna wanna be, um, doing a trade-off between y- you know, like, what kind of repairs.
You might be able to change the way you’re operating to reduce loads. Um, you might be able to monitor to make sure that your blades are safe. You know, if you know that there’s an issue, um, you just wanna get some advanced warning before blades start falling off your, your tower. Mm. You know, and then you can push it further.
Yeah. Whereas if you’ve got no information, then you have to be conservative and shut it down. Yeah. So yeah, I think there’s a whole lot that can be g- can be done there in that area.
Matthew Stead: There was a point that came up today, which I think was close to your heart, on, you know, if you’re going to be going for 1% or 2% or 0.5% AEP improvement, how do you actually measure that and how do you set up a proper experiment?
So-
Rosemary Barnes: Yeah …
Matthew Stead: I, I, I love that topic. [00:06:00]
Rosemary Barnes: Yeah. No, it’s one that I, um, yeah, I deal with m- my clients I, I’m often… It’s one of the things that Pablo really loves to do, is to organize trials of that nature of new technologies and see if they work. But, um, yeah, asset managers are usually very, uh, focused on fast results.
You know, they’ve got a, a big problem and they want a solution now, so they wanna just roll out the new technology over an entire wind farm. But if you do that, then it’s almost impossible. Unless you get, like, a huge benefit, like, uh, 10% gains or, you know, like reduce your failures by 50% or more, it’s really hard to actually- Mm
pick that out if you just replace everything. Mm. Whereas if you do a really, really good, um, trial plan- Systematic. Yeah … and you match pairs very well so that you have, you know, a control for each turbine and there’s- so many variables in a wind farm. It’s not, it’s not as easy as just, like, randomly choosing 50% to do and not do.
Mm. Mm. Mm. Like, you have to, you know, put some work into the trial design, and then, you know, like, do your statistical calculations ahead of time to know how long it’s gonna take you to get s- statistical [00:07:00]significance. So then you don’t just have a gut feeling about- Yep … how something went. You’ve actually got numbers, and then you can take those numbers to, you know, other wind farms that you’ve got- Yeah
and, and know what’s going on much better.
Matthew Stead: Worst study is an inconclusive study.
Rosemary Barnes: Yeah. Yeah, that’s true. Definitely.
Allen Hall: Well, that comes back to the data analysis- Mm … which a lot of operators mentioned, and how much data there is and what to do with it, and it did seem like a couple of operators have chosen some AI tools, varying degrees, all the way down from Microsoft Copilot to something much more complicated.
Uh, but I think there’s, uh, getting that d- to the last 1, 2, 3%, you’re going to need those tools- Absolutely … because what do you choose? Do you choose a blade? Do you choose a gearbox? Do you choose a generator? Do you go to the substation to get that percentage point or two Without having some really powerful tools- Mm.
you may be wasting your time [00:08:00] and money.
Matthew Stead: Mm.
Allen Hall: Which is a, a, a very interesting, uh, aspect to wind energy because it’s such an industrial business that, uh, we haven’t used heavy computational tools, uh, un- until really now.
Matthew Stead: Mm.
Allen Hall: And maybe Australia’s at the forefront because of the PPA and negative pricing is that that will, uh, actually lead an industry.
Because I haven’t seen a lot of that being used globally. Mm. So this is the first time an operator- Mm … that I’ve talked to has said, “We’re using it.”
Matthew Stead: Yeah. It’s quite a different discussion, um, I think, you know, this year compared to previous years in that I think in the past it was getting to know what’s possible, but now it’s like real case studies are coming through.
And a few of the people had some really good examples that we can talk about at the conference as to how they’ve actually been helped and how they did this and what the outcome was. I think, yeah, that would be really great content on that.
Rosemary Barnes: Yeah. I think it’s gonna be a good mix of people who have used third party tools and have experience with it, people that are doing it in-house and can share- Mm
some of the kinds of results- Mm … that, that you can get just from analyzing your own- Mm … [00:09:00] SCADA data. Um, people talking about how they get the data that they want. Mm. ‘Cause it’s not always so easy. You would think that, you know, you own a wind turbine, you have a right to have all of the data that comes through it, but it’s not.
Um, even if you do technically have a right, it’s, uh, it, it’s harder to actually get it than you might think. Mm. So yeah, sharing all, all those kinds of things. But I think also, like just as important as talking about the successes is talking about the, the gaps that– people still feel lots of gaps. Like, okay, we’ve got all the data, we’re collecting it.
We know that there’s so much potential here- Mm … but we don’t really- Mm … know what we can do, or it’s hard for us to, you know- Mm … make headway in this particular pain point. And that is really useful for companies that are developing tools to know what are the, the problems. Mm. Because then they can e- you know, they’re well placed to fix them.
Allen Hall: Mm. Which leads to the discussion we had with the operators and, uh, some of the suppliers for WOMA 2027. There’s a lot of interest. And as we’re sitting in the conference rooms, I’m thinking, we may not have enough room to [00:10:00] seat everybody. Uh, the WOMA 2027 website is up and running, and you can register now.
So just go to woma2027.com and get started there. At the same point, we’ve had a lot of contact with, uh, pretty much everybody that wants to sponsor the event, and there’s only a limited number of ways to sponsor. So if you’re interested in doing that, you, you need to go to woma2027.com and look at those, uh, part- particular packages and see what- Mm
fits your, your business. Uh- Going back to some of the, the comments we were just discussing downstairs about what we heard at 2026, like, which is only a couple of months ago, right? It’s back in February this year. Uh, there’s, they’re still discussing what happened at WOMA 2026- Mm. Which was very fascinating- Mm
because I think Rosemary, you and I have been to conferences that I have not thought an iota … about what happened at those conferences. Just nothing interesting does occur. There’s no new, new information, there’s [00:11:00] no new science, there’s no new operator approaches.
Rosemary Barnes: Mm.
Allen Hall: But we’re gonna see a number of those- Yeah.
Mm … come next March.
Rosemary Barnes: Yeah. Well, I think it’s partly because I don’t know what other conference organizers do, but, you know, we’ve had a exhausting few days here. You’ve come all the way from America, obviously, and, and Claire as well, also come over, our producer. Um, so, y- you know, like, we’re working really hard to make sure that the topics…
Like, it’s not an accident that the topics are ones that people are talking about later, because we come here to make sure that we get the right topics. And it’s not just these meetings as well. People get in touch, and- Mm … anybody watching, listening, who has, you know, something that they wanna talk about, then definitely, you know, send us a message, and yeah, we’re working on the agenda.
We’ll, we’ll have a draft agenda in the next couple of weeks based on what we’ve learned here, but then we’ve got the hard job of it’s not just that you have a really interesting topic, you need to have a really great speaker- Yeah … or several really great speakers, usually covering several different aspects of the problem.
You know, maybe it’s, uh, yeah, an asset [00:12:00] owner, an OEM, and some, some technology provider, you know, all together giving different, um, yeah, perspectives. That’s, I think, what makes a really great session. Mm. So yeah, we need the ideas for the sessions, and we also need the ideas for great speakers.
Matthew Stead: Yeah.
Rosemary Barnes: Right.
Matthew Stead: Yeah. I think we’ve, we’ve already matched a few of those dots, so- Yeah … I, we’ve heard people asking for certain topics they wanna hear about, and then we’ve heard other operators saying, “Well, this is what we could talk about.” So I think we’ve already-
Rosemary Barnes: Yeah, yeah … got some great
Matthew Stead: progress.
Rosemary Barnes: It was, it was interesting ’cause we, we built up a list of, you know-
Matthew Stead: Yeah
Rosemary Barnes: frequently raised topics, and then you’d say it to the next person that you went to- Mm … and they’re like, “Oh, that’s not a problem for us because we’ve done X, Y, Z.” And you’re like, “Okay. Well, excellent. You can, you can present the solutions that we know that other people- Yeah. Yes … are, are looking for.” Yeah.
So it has been… Yeah. Yeah. I mean, it’s definitely worthwhile coming, as, as tiring as it is. Yeah. Um, definitely worthwhile, and we’ll get a much better agenda for the- Yeah … for the effort.
Matthew Stead: And I think, I mean, it has been tiring. Um, but what, what made it for me was one of the operators said that [00:13:00] this is the only conference they will go to So I think, I think we’re doing the right thing.
Rosemary Barnes: Yeah. Yeah. I, I think so. I understand too, like, you know, all of us, we kind of are forced to go to events because that’s where our, our clients and customers are, and so you need to see them. And yeah, like I’ve even gone to the extent of some events where I don’t particularly like the event, but I know everyone’s going.
Mm. I just go and sit near the event for a couple of days and meet people at a cafe. So yeah, like we can’t get away from it. But if you’re an asset manager or, um, yeah, somebody in that kind of type of work, like you’ve got better things to do than listen to sales pitches aggressively thrown at you that aren’t relevant- Yeah
to what you’re doing. So, um, yeah. Like I, I definitely love to hear that kind of feedback- Yeah … and wanna make sure that we get it every, every year. Like that’s- It’s, it’s
Matthew Stead: encouraging.
Rosemary Barnes: Yeah … yeah, that’s, that’s the point of the conference, so.
Matthew Stead: Yeah.
Rosemary Barnes: Yeah.
Matthew Stead: The other big topic was we would really love more OEM involvement.
Um-
Rosemary Barnes: Yeah. Everybody wants more- … a lot of the operators- … OEM involvement- Yeah … all of the asset owners.
Matthew Stead: Yeah.
Rosemary Barnes: Like we want to [00:14:00] hear from OEMs more, have them there. Um, so yeah, we’re, we’ll be trying to To get those sorted
Allen Hall: Well, WOMA is a global conference, although it’s Australia-based and there’s a, a number of Australian operators.
There are Danish, Americans, uh, plenty of Europeans. Uh, we’re gonna see some from Southeast Asia, I think, this year. Mm-hmm. And, and Japan hopefully will come. Uh, because it’s a, it’s a global conference, there’s global knowledge- Mm … and wind is such a big industry. You may not have the solution in the United States, it may be sitting in Australia, and we need to exchange those ideas.
Mm. And that, that’s the point. So w- we are continuing to look for those world experts as we have received all the inputs of these are all the topics we wanna go hear about. Great. Now it’s on us three to go find some of those world experts and, and try to get them to Melbourne. Yeah. And I, I think that’s a great opportunity.
So if we do call you and ask you to participate in WOMA [00:15:00] 2027, please take it seriously because- Mm … you will be bombarded with great questions- Mm … and contacts and information. Uh, it’s an event you won’t wanna miss. Yeah. And- But I would- … there’s opportunity there.
Rosemary Barnes: Yeah. I’d say we’re, we’re prioritizing OEMs, um, to, to get more participation, ideally to speak, but at least to be there.
And we have heard from multiple asset owners in Australia that they want, they, they want to know what are some of the upgrades that they can do- Yeah … that you’re offering. They wanna know what’s coming next in terms of technology. They wanna know what are some of the non-Western options. So, you know, like it would be great to get some Chinese wind turbine, um, manufacturers as well.
Like, they want all this information. They don’t want a slick sales brochure pitch that doesn’t give them any technical information. So we’re hopeful that we’ll be able to get, you know, some technical people to speak on, yeah, what are the upgrades you offer and how does it work- Mm-hmm … and show us a case study that demonstrates the improvements.
Um, ’cause that [00:16:00] sometimes is really hard to get out of- Mm … out of OEMs. You know, that, “We’ve got this thing, it’s so amazing, you should get it.” Okay, well, what’s the business case for it? “Oh, well, we don’t have any numbers. Just trust us.”
Matthew Stead: Yeah.
Rosemary Barnes: Um, it’s so common to get a pitch like that. So yeah, any, any OEM that has any- anything like that, either for the next generation of wind turbines or for upgrading the current fleet, yeah, if you’re willing to bring the data, then people, they are desperate to hear this information.
Allen Hall: Mm.
Matthew Stead: Yeah. That came up so many times.
Rosemary Barnes: Mm.
Allen Hall: So what were the other, uh, topics that we’re… I’m just not thinking off the top of my head. I know foundations came up quite a bit- Foundations, yeah … which was an odd one, I think, because we haven’t seen that a lot in Australia. Yeah. But this year, foundations, foundations, foundations.
Basically, the health of foundations. Yeah.
Matthew Stead: Yeah. I think really there was a lifting of the maturity. Um, I think the topics were sort of showing that, you know, Maslow’s hierarchy and moving into the more of optimization rather than making do, and I think life extension around the foundations was a, a really good example of that.
Allen Hall: And bolts.
Matthew Stead: Bolts? Yeah, bolts.
Allen Hall: [00:17:00] Everybody said bolts. Bolts.
Matthew Stead: Bolts.
Allen Hall: You think the world’s simplest device, we’ve been making bolts for nearly 1,000 years or at least a couple hundred. But it does- And, you know- … come up quite often … cable, cable
Matthew Stead: terminations, again, some really
Rosemary Barnes: basic- Yeah, that, really specific ones that were raised multiple times.
Yeah. Um, yeah, which, which is great- Yeah … ’cause it gives us a good direction to go. But I do love how it changes so much every year- Yeah … ’cause it makes me feel like, okay, yeah, like we’re actually, you know, it’s worthwhile, um, putting on another event. Mm. Um, not just recording one event and then just, you know, like replaying that every year or something.
Re-educating.
Allen Hall: Yeah. Well, I, I think there’s a learning exercise that has happened over the past two years where people now are knowledgeable about those things we talked about- Mm … two years ago. Uh, was it, was it even two years ago? It was a year and a half ago when we first started this, so we’re, we’re not that deep into it.
Although our third conference will be next March, uh, you just see more energy, more industry knowledge in some of the references that I heard, uh, in terms of other companies and the approaches they’re taking clearly came from WOMA.
Matthew Stead: Yeah.
Rosemary Barnes: Mm.
Matthew Stead: Yeah,
Allen Hall: yeah. Which is, which is [00:18:00] fascinating. Yeah. That’s
Rosemary Barnes: good. I mean, we want- It, it is
Allen Hall: sticking
Rosemary Barnes: we want tech conferences to get better, right? That was the- No … the reason why we, uh, we started this conference was ’cause we didn’t think that it was sufficient, what we had available. So, you know, it’s not a bad thing if other conferences, um, get better. Yeah. Yeah. We should also mention that blades were, were raised a fair bit.
We talked so much about blades in the previous years, and we will be talking about blades a lot again, including we’ve got a master class on the Friday. Uh, it’s… Yeah, we’ll go back to some of the basics about how the composite materials work and how a blade is designed and certified and manufactured, and, um- Lightning.
Y- yeah, yeah, a little, a little bit about lightning. Um, I don’t wanna cover it too much because we did the master class on lightning- Right … last year. Mm. Um, yeah. And yeah, some of the common damage methods anyway. And of course- Mm … yeah, lightning is probably the most- … common, or I guess leading edge erosion is the most, and then lightning would be the most expensive.
Um, yeah, so we’ll be, we’ll be covering all that and just try and raise the knowledge level a little bit, um, for [00:19:00] everybody to… It’s a very complicated kind of, uh, yeah, component.
Matthew Stead: Yeah.
Rosemary Barnes: Yeah.
Matthew Stead: And workshops. So each year we’ve run sort of workshops or roundtables or whatever, so we’re still thinking about the format for them, but, um, thinking about how we’ll reintroduce them again this year.
You know, specific topics, specific questions, specific answers.
Rosemary Barnes: Mm.
Allen Hall: And the three of us will be in Hamburg in a couple of weeks at Wind Energy Hamburg, so if you see us and you’re interested in coming to Australia, that’s the place to grab us and- Yep … and shake us and say, “I wanna go to Australia. How do I do it?”
Rosemary Barnes: Mm.
Allen Hall: Uh, yeah. Yeah.
Rosemary Barnes: Especially if you’ve got a, a t- technology that addresses some of those specific issues that we’ve mentioned- Mm … then, um, yeah, just know ahead of time that Australia needs, needs more information and more, um, solutions available to them. So, yeah. And
Matthew Stead: that reminds me, we had a really discussion a- around safety and, you know, reasonable and [00:20:00] practicable, and discussion around all the lessons learned about how…
or what is best practice on a site, what is best practice about how to manage risks and-
Rosemary Barnes: Mm.
Matthew Stead: Yeah. Yeah. I know you, you, you enjoyed that one.
Rosemary Barnes: Yeah, yeah, definitely. And we’re not talking about, like, safety the- Ear muffs or hats. The, um, rou- Yeah, the routine safety that if you- The goggles, yeah … yeah, trip over and graze your knee, then you need to let the site supervisor know.
You, you know, it’s not that stuff, ’cause sites have that under control. That’s a given, yeah. Or at least the ability to get that under control. We’re talking about the bigger- Yeah … bigger things, you know. Like, uh, is there a issue that is causing blades to fall off turbines every now and then? Is there an issue that, uh, can lead to, you know, a fire?
I, I think everyone, like- Yeah … a big fear of everybody’s. There’s never been, um, in Australia at least, there’s never been a wind turbine fire that has caused a bush fire, but it is a possibility, and it would be so bad for the industry. So, you know, it’s those things- Mm … that could be just terrible, preventing those before they happen.
Mm. So that’s the kind of safety that we’re gonna mainly focus on. Mm. Although, you know, we’re not gonna [00:21:00] turn down questions on, um, some of the smaller stuff as well.
Matthew Stead: Yeah.
Rosemary Barnes: Mm.
Matthew Stead: And we even thought about getting some lawyers-
Rosemary Barnes: Yeah …
Matthew Stead: you missed out on this discussion, Rosie. Okay.
Rosemary Barnes: Yeah.
Matthew Stead: So
Rosemary Barnes: Yeah. Lawyers, this is news to me.
Well, I mean, are we talking contracts or, um-
Matthew Stead: No, no … no … it’s really operations. I mean- Right … the environmental, um, issues- Oh yeah … the operational issues. Mm. You know, there’s, there’s a few things in there that the lawyers can add.
Rosemary Barnes: Yeah. I mean- … I’ve, I constantly find myself having to interpret, you know, legal, um, legal text and also anticipate, you know, it’s one thing about what’s the right engineering, but then there is also the legal interpretation of it- Yeah
uh, as well, you know, in terms of contract law, but then also in, in terms of safety. Yeah. Um, yeah. Was this certification done correctly? You know- Yeah … that’s got some legal aspect to it. So yeah, that- Yeah … makes sense to me. Insurance is another one where I would say- Yeah, actually that came up … you know, like some, some people might think that that doesn’t sound interesting, but yeah, in- insurance is the other-
Matthew Stead: Mm
Rosemary Barnes: aspect that you [00:22:00] just can’t, um, you can’t get away from it. Like, you can’t just think that you’re, you’re doing your engineering without bothering about Mm … yeah, like finance and law and, um, and insurance. Those are things that- Mm … you spend a lot of time thinking about.
Matthew Stead: Yeah. Mm. And I guess we would also love to hear, you know, about potential speakers, but we’d also love to hear any other topics that people are attending and want to know about as well.
Rosemary Barnes: Mm-hmm.
Allen Hall: Absolutely. And if you haven’t registered for WOMA 2027, which will be March 3rd through 5th at the Pullman in East Melbourne, right? East Melbourne, yeah. They just redefined it. It’s Pullman in East Melbourne. Uh, go ahead and go to woma2027.com and register now. Uh, Matthew and Rosemary, it’s great to see you in person again, and we’ll see you in a couple of weeks, uh, hopefully in, in Germany.
Rosemary Barnes: Mm.
Allen Hall: Very [00:23:00] exciting.
The substance of the meme here is correct; Florida public schools require comprehensive K-12 instruction on the history and dangers of communism, following a series of legislative moves and curriculum standards. The updated “History of Communism” curriculum is rolling out for the 2026–2027 school year, mandating that students learn about the “brutal realities” and (the catastrophic) global impact of communist regimes.
When I was a schoolboy in the 1960s and early 1970s, we came to learn that all efforts to establish a viable communist nation had failed, but our teachers were not shackled as to what they could teach and how they could teach it. As a result, we came to a variety of helpful viewpoints, and these are what I offered my own kids as they were growing up, e.g.,
- “Men are not angels,” as my sixth-grade social studies teacher explained. Those who do not need to work in order to survive can simply goof off.
- Yet idleness is averse to most people’s psychological needs to be an active and productive person, and member of society.
- Power corrupts, and absolutely power corrupts absolutely. Democracy prevents the accumulation of a pathological amount of power on the part of any one leader. (This was assumed to be true until Donald Trump’s second term.)
- If Lenin (a butcher) hadn’t had Trotsky (a compassionate intellectual) assassinated, the entirety of the USSR would have turned out completely differently.
- If the U.S. hadn’t, through its embargoes, made it impossible for Cuba to offer its people a decent quality of life, their revolution may have succeeded and brought forth a new way of thinking.
- There are examples of smaller scale societies in which the ideals of communism work out very nicely, e.g., the Israeli kibbutz.
- We read and discussed at length a book called “Social Ideals and Ideal Societies” in which these concepts were analyzed fairly and in great depth.
Now, will the typical American schoolchild turn out better if he’s cut off from thinking critically about all this and forced to accept the mantra that “communism = evil?” The typical Florida Republican would say the answer is an obvious yes, but most intelligent people would dispute that.
Producing educated people who can think for themselves is an idea quite opposed to the ongoing control of a population.
To the author of the meme here, I say: It’s safe to say that most folks in Trump’s MAGA base are stupid, though one needs more than a low IQ to fit into this segment.
In particular, we mustn’t omit mean-spiritedness. People who are kind, compassionate, decent and tolerant of others are grossly unqualified to be rank-and-file Trumpers.
