Allen Hall: Alright, Armando, welcome back to the podcast. Thank you guys. It’s a pleasure to be here again. Yeah. It’s been a couple of months since we’ve last had you on the podcast. But a lot has happened since then. Earth, wind, obviously huge Brazilian presence. You guys are working with most of the operators or much of most of the installed base in Brazil, and you’re expanding out into the United States and other places.
But the product offerings you have created over that short time span since we last talked are quite amazing and you want to announce this new software product. It’s called what? ArthNex.
Armando Costa Rego: Art Next, yeah. Yes. Yeah. This predator came from the idea to, to go deep in the value chain of the hippers, you know, everybody in the march, I think since 2017, the industry has experienced, uh, a fast improvement in the drone solution, the rover that we started like four years ago, and everybody’s talking about how long it takes an inspection and how long pressure to produce in minutes.
So we are talk 30, 20, 25. For me, what matters if we, we create data to hipper, so the, the discussion of the architect is, okay, we jump into this phase of, to discuss how fast an inspection we are now, uh, uh, using this data to provide it to the owners in operators, OEME, whatever, in the player in the market would be interested to use our.
Maybe he pair knowledge capabilities to go direct to actions that can prioritize what to do, how to do, and sometimes why to do. Yeah, that’s the question. Nobody do this question why to do that. Yeah. Those make sense or not? So the data will tell you what makes sense or those not make sense.
Joel Saxum: Yeah. So what, like when we look at most platforms out there, asset management blade inspection platforms, it’s here’s your inspections, here’s the findings from them.
Here’s a
Allen Hall: spreadsheet.
Joel Saxum: [00:02:00] Stop. Yeah, that’s it, right? There’s that. There’s no just looking at the earth Next platform. When Alan and I were peeking at it yesterday, it was like. Here’s a dashboard that shows you where your leading edge erosion status is on, on all your whole fleet. And this like, oh, that’s great.
Like, oh, your overall risk score is this, oh, this turbine has a risk score of that. Like, oh, what’s going on here? These are the ones that you need to stop now. Look at in two weeks, look at in 12 weeks, like. There was actionable data and that’s before we even get into the operational part of repairs, but actionable data that you can look at dashboard.
Now I know what decisions I need to make today.
Armando Costa Rego: Yeah, that’s right. That’s right. So it is a clean data, it’s clear data. We can interact with the image. We are not focused in show, like the entire blade in the platform because that consumes a lot of dev time of development, you know, so, and we note that only 4% of the emails have something to tell you.
Yeah, right. So some point of internet. So we work exclusively. And that information that’s really useful to the operator.
Allen Hall: Yeah, and I think that’s the problem, right? Is that when we get drone images or internal inspections, there’s a lot of data. Yeah. That then as we’ve talked to operators in the United States, we have engineers, usually junior engineers, going through all that data, trying to pick out what’s important and what’s not important so that they can develop a plan themselves internally, but they’re wasting.
Thousands of engineering hours doing it. Yes.
Joel Saxum: And the tr one of the troubles that we talk about regularly on, on the show is lack of technicians, but also the lack of engineering knowledge and support. So when you have a blade engineer that’s, this regularly happens in the states, I’m in charge, I’m the blade engineer, I’m in charge of a thousand turbines.
What? So they don’t have the bandwidth to take care of, to look through all of these different things, and that’s where the earth wind. Team with the Arthrex platform and all the engineering expertise you guys have in the background can help operators like that out a lot because they become their, you know, turn the tap on, turn the tap off blade engineering team that they can use.
Armando Costa Rego: Yeah. You know, in ArthWind we combining, we have a tried that we involve right people, we are talking about knowledge. And the experience of these people. Out of the 140 people that work for art in Brazil now have experienced some parts of the value chain, or in blade design, or in blade manufacturing, or in the OEME or make root cause analysis in broken blades.
You know, so we cover all life cycle. And the second pilot is technology. So we were the first company, maybe the, the South hemisphere in the world. To make an inspection with autonomous drone back in 2017. So in Brazil there nobody was talking about drone. And the last one is methodology. We are. Very confident that we cannot change the methodology, otherwise we will have a mess with data.
So since 2017, we created our own blade book, just to be straight to what this data does means. Yeah. Okay. If there is another, uh, categorization, for example, everybody’s talk about categorization, that’s a huge discussion. I disagree that we need to categorize from one after five. You know, I think that blade can talk much more than five levels.
Uh, but when you have our own methodology, we can combine the data from the inspection that we did from the ground, from in the manufacturing, and we can have a much more clear view during a root cause analysis when you will go to the blade, the data book and check the results. Yeah, that is no confusion.
If you crack, if the elimination, if the a Cat 5 is a Cat 3, we tell the history of each damage and the cause, the potential cause of those damage because our engineering is backed by blade designer. So they know what they are looking and what it, it can make this damage happens in the field, you know?
Allen Hall: Absolutely. And I think, uh, something that’s missed for American operators is realizing the talent that sits in Brazil, because Brazil was a blade manufacturer. That’s right. Long before America really started ramping up in blades and then even after America slowly stopped making blades. They were still being made in Brazil.
Yeah, so the, the manufacturing technology is in Brazil. The engineers who design blades and know all the inner structures of the blades and how to repair the blades and why certain blades performs this way and other, and others that way, that knowledge base is in Brazil, which makes art wind so. Valuable because you have just a huge people resource that doesn’t really exist in other parts of the world.
Maybe the only a place I would assume is like Denmark is where you have that kind of relationship between people that worked in the factory and understand how the bill blades then moved up to engineering and then moved up to management. That’s kind of there. But your people are hard to find in the states.
Yeah. And that and that thought process that goes along with it because you had to suffer through all the things that happened in the blade factory and then out in the real world. You develop some of these systems long before United States operators have. So that gives you like. Literally a 15 to 20 year jump of what’s out there otherwise, which is why Earth Wind is so valuable and whatnot, which I don’t understand why American operators aren’t using your resources as much just because you have the technology, you have the knowledge
Joel Saxum: and that, and now, like today, we wanted to make sure we talked about Earth Next, the new platform.
Yes. And that knowledge base is what built that platform. Absolutely, it did. It’s people that understand the whole value chain from manufacturing. I guess this, this sounds like a sales pitch for you, but we liked it so much when we saw I was blown away a lot,
Armando Costa Rego: you know? You know, yes. Back into 13 x we, we spent the last, the last seven years only processing data from the inspection, but we, all of us came from the Heary industry.
Yeah. Yeah. I started the business of in Europe in 2009. Yeah. Yeah. So I was dispatching two technicians for 23 countries like pizza, you know, 48 hours with, yeah.
Armando Costa Rego: And I, I thought that the way that we was managing repair 15 years ago. It’s not the way that we can accept anymore with modern blades, because if you see the margins, the uh, uh, the safety margin of the blades do not allow lack of no less during the hip air.
So that point that a x will play a crucial value in this field, because if you go to the hipper, everybody talk, uh, how long takes your inspection, doesn’t matter how long are you, save you in downtime with my data because. The new feature of the architect, we are going through the hip air value chain and we are broken in pieces, each task, and connecting the field technician direct with engineering.
Yes. What happens in the industry today after your technicians go? With a standard procedure, they start to grind. So it take three hours maybe to access the damage. They start to grind, Hey, I found a wave here. There was nothing procedure. So they climb down. They full stop. Yeah, let the turbine stop it. Go to the engineering by WhatsApp or whatever else saying the engineer, start to prepare the word documentation and send back to the, to the selected.
This is if you’re lucky.
Joel Saxum: Usually this is like a 24 hour delay in process. Oh, easy.
Armando Costa Rego: You know that it can take like 48 hours in downtime. So we are very focusing in reducing inspection time. But what is looking how to help this parts of the value chain and the aex? We do, we connect the technicians through the app with the standard procedure and if they, uh, found something different, they immediately in the tab, they press the button.
That it will be a pushup in the mobile, the engineering that you will start to work to the hip air. Yeah, no, you’ll not wait till overnight process. For tomorrow day, you solve the doubts of the technician not preparing a word. Give instruction because they know what to do and they just need to redact and say the instructions and pictures.
Send mockups, send the drafts, handmade drafts, you know, just to give you more research to the technician. Take decisions. You [00:10:00] know, and it, we are looking that we are already saving a lot of downtime in Brazil with this technology that we have for a customer applying, and the, the data that we are collecting is a good feedback from the blade repair companies.
Because it’s making the life of the bladed technicians much more easy. Yeah. They do not need to arrive in the hotel tired and prepare the reports. No, the work is done.
Allen Hall: The back office work is being done. Which is need in real time. In real time. Yeah. That, that’s the beauty of what Art Next is doing because you.
Been through the other way of doing it. Yeah. And you’ve seen how lossy it is and expensive it is. And the delays and the technicians you’ve created the platform though, that is easy to access. And I think that’s the, the hard part for a, a lot of people to grasp about Artex is you’re putting all that knowledge in a mobile phone.
It also appears on a desktop for the engineers to go through the, the communication interface is so much better than the WhatsApp we’ve been doing. Yeah. Text message, text messages, and also the track and
Armando Costa Rego: the data, the history of the, the story line of defect because when we broke the value chain of the hip air, there is a complex tasks.
Yes. Maybe a simple prepared 12 tasks. Right. Grinding, cleaning, et cetera, et cetera. So when we transform this offline data is online data. We generate gorgeous metadata, you know, because we can, uh, measure the fishings of the campaign, right. And also, uh, a second point of our tool that we control the quality assurance.
What kind of materials being employed, right? What’s the calibration certificates?
Joel Saxum: Yeah.
Armando Costa Rego: So we, we provide a, a full quality assurance services digital to the customer. For one year later, if there something is happening, you have all documentation of the damage. So you can use that with insurance companies to score qualified new suppliers for sure.
Yep. ’cause we are raising the bar of the quality controls of the industry.
Allen Hall: Yeah, and that’s the big problem I see mostly in the states, is that when they have an ISP show up on site. They don’t have discreet hours of how long it took to do this repair. They don’t know why it took longer than it did. They haven’t looked at how long should this repair really take and how do I budget this properly?
On top of it, I’m just getting a PDF after it’s done. I don’t see anything live. Yeah. So to speak, which is a huge problem because I think US operators don’t, can’t realize how much money and time they’re losing in that. Space. It’s millions. Millions of dollars. Millions of dollars. Easily, easily, easily. And that’s where Artex comes in because now you’re tracking ISPs, you’re tracking almost to a technician level the quality of the work engineering consisting of the work, the engineering of the work.
Right? Exactly. So now what? When I’m starting to do repairs, I come, I come in much more knowledgeable. And I have much better cost control measures in [00:13:00] place when I do it. So I can watch it go. I get alerts when the budget is running out. Yeah. Right. So that the, something happened, I, I got assigned budget to this.
I can’t go over, I need to know that our next provides me that, that look real time as the repair is happening. Um,
Armando Costa Rego: those are huge advantages. Uh, you know, I, I think that. Okay. We need to agree that to, to make bleed he air in the environment, in this environmental that we are living now with climate change, et et cetera.
That storm, we never have been some storm is knowing we’re so people is not ready how to plan. Right. So, uh, it’s very difficult to forecast how long you’ll take the repair today.
Speaker 4: Yeah.
Armando Costa Rego: So if you have more data. We can, uh, uh, learn a little bit more about that location to schedule or to make the, a better strategy, not changing the hip repair methodology, but change the chron, the, the timing.
Yeah. When to do that because, you know, sometimes I recommend to my customer to inspect the blade, the high wind season. That’s crazy. You lost production. No, you lost like. 30 minutes, but you, you prepare your campaign that that is the point. You know, you lose a lot of money, you know? Right. I think you, you’re touching
Joel Saxum: people on all sides of the value chain with the Earth Next platform.
So you’re making engineers happy by giving them qa, qc. Yeah. You’re making the procurement and the finance people happier because you’re optimizing the repairs themselves. You’re saving money there. Material. Material control. Material control. The asset managers like so from, I put my asset manager hat on when we were looking at the platform yesterday, and I see this.
Basically this entire health timeline of the blade, like from the factory inspections we did to the post commissioning end of warranty, all through the whole thing. It was like, on this date, we did this. On this date, we did that. And you’re able to see it in a flash
Allen Hall: in, in a graphical form. Yeah. Easy to digest.
It’s not images where I have to keep clicking the image to see the thing, and then I gotta figure out how a crack is progressing. It’s broken down, so it, it is visually easy to scan, which is what engineers have been asking for for the last five years, is I need to go in and scan a thousand blades. I need to know which 20 I’m gonna go look at today.
But I don’t wanna spend eight hours on each of these blades because I’m wasting my time. Going to Armando’s system and ArthNex, I can scan it. I know what my top priorities are for the day. That is an important feature as we get more cost conscious. And over the last, well, we had an election in the United States.
You may have heard about it, but we’re getting very cost conscious about how we spend our money. Are we spending the money wisely? The way that we’re gonna do that is with systems like Artex that’s gonna help us save money, be more efficient, get the repairs done, and extend the life of these turbines and produce more power.
So it ultimately comes to power?
Armando Costa Rego: Yes. Because we are connecting engineering. Yes. So the field. Yes. Without going to the building. So, uh, I have had some situation with field technician that where there, I don’t know what to do here. You know, and they do wrong tasks. No, it, we will, the damage will be still there.
So we go, okay, we can make a good finishing. Okay, but three months later we will, the crack will be still there. So I think that uh, uh, uh, one of the main points differential of our snacks, uh, people is asking, Hey, how fast did you do develop data? Two years, but there is a knowledge of 20 years of experie of my team.
So, and the, the best parts of that job, product owner, for example, he came from the field, he was a field inspector, so he started to. Creating small, uh, uh, uh, uh, programs to make his life better, you know, to make automated report. And you saw, hey, I think that we can create our own technology on that. So when you have the, the, the both of the developers that have been the field and really smart guy, I think that’s very [00:17:00] quickly to digitize the industry.
Uh, if you go to the positive, for example, if you are only a tech company and you try to figure out. What to develop. It’ll take longer. You’ll need much more trial, you need much more feedback. But when we know that we’re digitizing from fields. To the office much more fast. The, yeah, so,
Allen Hall: and the, uh, one of the advantages to the Earth next system is a lot of operators have 3, 4, 5 years of drone images, external, internal plus repair, PDFs, generally speaking their PDFs.
And if they wanted to implement the Arthrex system, it would be easy to do. You’re just gonna import that into the system. Arthrex is gonna. Digitize it, digitize it, and then analyze it so that you can see those trend lines almost within a couple of days. I think you could be up and running with the our next system for a lot of operators in the United States or globally Australia, I think in another place.
Yeah, they could use it. You’re gonna be busy. Armando, I you’re gonna be on an airplane quite a bit. Yeah,
Armando Costa Rego: we do. We actually do that. Uh, we have like customer, I, I think that we are achieving four gigawatts of contracting. Yeah. That’s Wow. But we feed three years contract, but we inspect more than 20 gigawatts per year in Brazil.
Right. For the spot inspection. Yeah. Which,
Allen Hall: which is important for everybody to understand. So what earth wind is doing in Brazil is. Gigawatts after gigawatts after gigawatts of inspection, which doesn’t really happen in the state and historic call. Historical year by year. By year. Yeah. Right.
Joel Saxum: That’s the trust, right?
Allen Hall: That’s the difference. There’s the trust
Joel Saxum: that that market has in you guys to get the solutions, right. Um, we want to export that. Yes. Let’s use that trust. Let’s use that track record to help. ’cause I mean, we talked about some of the successes that you’ve had, of course with Earth Wind, but with just the art Next platform guys have like four gigawatts you’ve onboarded here and then.
Yeah, on multiyear contracts, like great. Yeah.
Armando Costa Rego: And plus for megawatt wind turbine, so it’s modern turbine, auto turbine. We have a mix of technologies there. And also, uh, looking to what is the next, I think that we need to be much more concerned. Everybody’s talking about the standardization inspection, but we can go through the hipper as well.
How to communicate a hip pair, how to report. So if you go to the ax now where you press the bottle automatically, you have a beautiful report of five page.
Joel Saxum: Yeah.
Armando Costa Rego: Wow. We are receiving not 60 pages. Oh yeah. 60. No, it doesn’t matter. Not a photograph album for the wedding, you know, so it’s, uh, we need to have a registered to be used technically in the future with insurance company, with some discussion, technical discussion with OEMs, owner, et cetera.
Uh, but I think that the most beautiful is really to digitize this knowledge, you know, and put in the front line because our, we are very obsessed with the front line. We are always thinking how Aex can be better to the field technician because they are our customer. If they don’t like nobody use, so we are collecting this experience.
We are talking with technician. What’s the challenge of language? What the challenge of technical information doesn’t make any sense. To make a high technical procedure for someone that just need to understand, hey, how kind of layer. How is the size of the, the scarfing and how much product I need to prepare.
So we don’t need to complicate the terminology to the field operation. You need to make it easy, and I think that ArthNex will cross this bridge. Yeah. Yeah.
Allen Hall: Well, I, I want to touch on the insurance part of this. Yeah. Because insurance companies, as Joel has mentioned a number of times, run the world. So whatever insurance companies will pay for is what the industry will do.
What they won’t pay for, uh, is not gonna happen. And, but getting insurance buy-in into a system like ArthNex is really critical because they see the consistency of the repairs, they see the quality of the product. They can track it. They can also see where maybe an ISP is not doing the right thing and say, Hey, all right, you know, we need, we need to get address that.
The insurance industry is, is overseeing all of this at a tight level and they would love to have access to Aex to understand general trends that are happening in the industry. In
Joel Saxum: terms of blades. Exactly. I’m saying that dashboard, that quick look at a wind farm. If I’m a, if I’m an engineer, a renewables engineer from an insurance company.
And it’s renewal season and now I have to look at a hundred wind farms and some of them are printing out our next reports that are just like, risk score. Here’s this, here’s the top five, this is what we did this year, here’s my timeline. Boom. Check. They’re good, right? Boom. Reduce deductible. You’re gonna reduce the for
Armando Costa Rego: record that I have two keys to talk about.
Uh, you know, I think the info information. Affect the valuation of the wind farm. Yeah. We cannot forget that we are in m and A market in Brazil, for example. A lot of position in Brazil. Big companies are quite a big one. Right? You know, and the way we have the information organized, we have all technical details.
And the buyer will see this information, Hey, I can buy this risk. Yeah, yeah. Right. So you increase your valuation. But when we hide information, okay. Nobody buy. So decrease the valuation. Yeah. Due diligence becomes quick. We do a lot of due diligence. Brazil. Yeah. And when? When the buyers see our documentation.
Okay. It’s very well, I know that there’s a methodology that people, who knows what is saying. Okay. That is the documentation. And also a second point of insurance. I have a good case now we have good relation with insurance company. We do not work directly. But they told me sometimes, Hey, if I see this kind of dashboard, I can buy this risk.
’cause the problem is buy a risk that I do not know. Yeah. So if this li of management, I can reduce the premium and they can do more inspection. They can do more repair, they can be more proactive, you know? So I think that we need to join this mines to create value to the market, the industry, you know,
Joel Saxum: for that, that, that, that process.
Think about this, we’re gonna go buy a truck, right? And I’ve got two of them sitting there, but one of ’em. Has maintenance booked every record, every oil change, every tire rotation. What do rotation you do? Yeah. Yeah. And then it has a platform that I can look at it in. I’m like, I’m gonna buy that one. ’cause it’s reducing my risk.
Yeah. It, it gets rid of the worry. The one with all the details and everything organized well for me. That’s what I’m buying.
Allen Hall: Right. So Aex has sort of broken that barrier. Yeah. That we’ve been up against for the last couple of years in terms of understanding globally what is happening to Blades, how we can more efficiently take care of them, update them, keep them in good repair for a longer time without spending so much money and so much engineering time.
Spending around that is a huge value to the industry, and I know. I just saw Artex for the first time last week and were just blown away by it. ’cause I’ve seen a lot of operator inside monitoring systems and the spreadsheets and the picture and yeah, they’re kind of the same. They’re roughly the same.
The ui ux is different, but what the data you’re getting out of
Joel Saxum: is basically the same. It
Allen Hall: is. And it’s, it’s not super scannable. Yeah. And then the RX comes up. Mano says, look at this. But you know, I, even, I electrical engineer
Armando Costa Rego: understood what to do with those blades. You know, uh, we are a good threat company.
We are not selling product to investors or vc, et cetera. So we are selling product to the market, you know, that solve the problem of the industry today. Not tomorrow. So we need to solve the problem in the industry today. Okay. Right. Uh uh, what I see on that is everybody’s looking for a SaaS.
Yeah. SaaS doesn’t work without people.
Armando Costa Rego: Right. So our business model engineering as a service, the software is only the communication channel. That’s the problem. So we have people, we have an hour in Brazil, 25 people giving instruction to the customer through the platform. Wow. Have the AI in the platform. The ArthNex now brings the AI for this typical question, Hey, how many blades I affected with seven, five in two seconds.
It’s faster than to go to download the hip or call someone. The AI will tell. So for basic question, the AI is there for, even for, uh, people that don’t know nothing about Blades. Yeah, just it’s channel system, you know? Yeah. We’re having the hipper, uh, environment of the artex. We have a chat that we can send message, general message to the field.
For example, imagine that you are loud. Managing hundred drills that are more than 200 technicians. Yeah. And need to communicate something. Yeah. Now that’s important. So when you go in the shed, you select the work orders where you need that, this communication go through and you’ll send a note Now. Hey everyone, stop the work today for a safety induction.
So for project manager to have this level of communication and log in the platform that that is historical is very powerful because it’s very difficult to put everybody in the same page. Yeah, yeah. Oh yeah. Fragmented also for safety conditions. Yeah, yeah, for sure. To have the finding, Hey, everybody, stop their work.
Lightning. Yeah. The same time, right?
Allen Hall: Yeah.
Armando Costa Rego: You know? Yeah. So. If you are talking that the industry is paying like, I dunno, a hundred, $120 per hour per technician, why not you pay $40 per for a starlink to have this kind of connection that you save a lot of money in the
Joel Saxum: states and safety. This works at almost every window everywhere.
You’re not everybody. Not so much for you guys. Yeah. Well,
Allen Hall: yeah, we’re working on that. Elon’s working on that. So as an operator and a lot of operators listening to the podcast, in fact pretty much all of them do worldwide. How do they contact you to learn about Aex and get that demo so they can see this thing live?
How do they go about doing that? Do they just Google ArthNex, A-R-T-H-N-E-X and then it pops up or they go
Armando Costa Rego: to your website? Uh, they’ll go, they’ll find more details. Direct refers. So they can go to the commercial@arthwind.com gear or like to me. I’m very pleased to talk about ArthNext with everyone. No, because I can solve a lot of doubts.
I’m very, to talk with people is a product that I, we really believe that’s changed the industry, you know, so, yeah. So they can reach me out in Armando Costa at. Our twins.com. Do beer w beer.
Armando Costa Rego: Don’t not forget the beer com.
Allen Hall: And we’ll put Armando’s LinkedIn information please to the show notes so everybody can follow you and, uh, follow our next.
It’s a truly remarkable product. I know you’ve spent a lot of time developing it and it’s been vetted out. Now’s the time to get it globally out there. Yeah. Armando, I love having you on your podcast just. Such a resource for the wind industry. So thank you for appearing. Thank you guys. Thank you.
Armando Costa Rego: Thanks, buddy.

Do Social Democracies Commit Genocide on Their People?
Re: the meme here that a reader sent me, I’m not sure this is fair.
What social democrats are proposing exactly what most of the governments of Western Europe, and many other countries around the globe offer their citizens.
I don’t read too much about genocide in Denmark. Are they killing each other with pastries?

German Wind Turbine? Let’s Do Some Math
The turbine presented here has blades that are 0.5 meters in length, and that the average home requires 1.2 KW.
When we plug this into this wind power calculator, we learn that we’ll need an average wind speed of 37 mph.
Since the average wind speed in Germany is 11 mph and power is proportionate to the cube of the wind speed, the average German will need 38 of these to power his house.

What Operators Want to Hear at WOMA 2027
Weather Guard Lightning Tech

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.
