The first wave of digital grid infrastructure in the U.S. didn’t quite deliver on its promises. More than 100 million smart meters have rolled out across the country, buoyed initially by billions in federal funding. But instead of using them for exciting things like time-of-use pricing and automated demand response, utilities used them for more mundane things like automated billing, according to a whitepaper from Guidehouse.
Could the new wave of AI-based grid tech be different?
In this episode, Shayle talks to David Groarke, managing director at the energy consultancy Indigo Advisory Group, who co-authored a forthcoming Latitude Intelligence report on utilities and AI.
David says that AI shows promise so far. Unlike the first wave of hardware-focused advanced-metering infrastructure, AI leans heavily on relatively cheap software and data. He also says that AI’s capabilities are advancing quickly (“doing press ups” as the Irish say) by improving algorithms, handling more tasks, and improving efficiency.
David and Shayle cover use-cases and other topics like:

Announcer: Latitude Media. Podcast at the frontier of climate technology.
Shayle Kann: I'm Shayle Kann, and this is Catalyst.
David Groarke: In that last round of investment, it was generally large platforms. It was all communications infrastructure and hardware. So I don't think the original investments played out, but I think that is exactly why AI is interesting in the sector right now. Low cost solutions with high ROIs is what the name of the game of the sector is now.
Shayle Kann: All right, time to gear up as the AI hype and/or reality wave crashes through every sector of climate tech. This week, utilities. I'm Shayle Kann. I invest in revolutionary climate technologies at Energy Impact Partners. Welcome. Well, you already know this, I suspect, but let me just confirm for you what is happening and has been happening inside the boardroom of, I think, basically every large company in the world, which is at some point the company leadership in the board ask and attempt to answer the question of what AI will mean for their business. Is it a threat? Is it an opportunity? What should we do about it?
And I think in some sectors it's pretty obvious that AI is going to transform big businesses, like, if you're in the legal profession, for example. In others, it sure seems like AI should play a big role, but it's less obvious exactly how and when. And that's how I would categorize AI for utilities in the power sector today. They operate an extremely complex system that is full of data that could be leveraged for various versions of optimization, cost reduction, decarbonization, efficiency, reliability, all the things that you want.
So there probably should be something big there, but as we all know, everything in electricity is more complicated than you think it should be. That has, in fact, been my primary learning after having spent a good part of the last 17 or so years thinking about it. But there are things happening here and it could be transformative. You just have to look closely. So let's see what's what. David Groarke from Indigo Advisory Group has been working with utilities on AI since before it was cool, so I brought David on to run through the state of affairs with regard to AI in the power sector today. Here's David. David, welcome.
David Groarke: Thank you, Shayle.
Shayle Kann: Let's talk about AI in the electricity sector. I haven't talked enough about AI probably on this podcast today, so we're going to make up for it today by using the term three or 400 times in the course of a 45-minute conversation.
David Groarke: We'll do our best.
Shayle Kann: Yeah. It's a topic that everybody is talking about in every sector. So let's start with, why this one? And maybe talk a little bit also about why maybe not this one, but starting with why this one. Why is the electricity sector or electricity and gas, I suppose, the world of utilities, why is it an especially interesting one with regard to the possibility of new applications using AI?
David Groarke: It's a good question and it really is kind of the biggest question that folks ask, is, how does AI apply to the electricity sector? It's maybe not something you equate immediately, but I think the thing to say, Shayle, is that there's been a ton of investment in IT infrastructure and OT infrastructure and all of these smart meters. We're at over 70% smart meters in the US. There's all this digital infrastructure, and this is from years of vendors and rate cases and so on. So there's an appetite right now to prove out some of those promises from over the years and utilize all of this data and whatnot. So I think that's interesting. I think what's more interesting is the actual problems that AI is trying to solve in the sector.
If you stand back and you look at what the power sector is trying to do and take a leading role in decarbonization, and you think, "Right. Well, if AI, supposedly, is a set of computational processes that can perform a task at human intelligence, I mean, the scope is actually enormous in that regard." So AI has been put to use on various parts of the grid across the whole value chain. There's a whole set of use cases, but primarily it's been pointed at a set of problems, and it's using all of that data that's been gathered over the last number of years. When we look at use cases, they generally relate to top-line issues in the sector, and that's where the activity is.
Shayle Kann: So I definitely want to run through some actual use cases because I think that's often the thing that's lacking in these conversations. But before we get to it, I do think there's an interesting point in there which is, you and I together lived the world of smart grid 10, 15 years ago, whatever that was, and that was pre this AI wave. We were talking about "AI" a little bit at the time, but I don't think we meant the same thing that we mean today. And yet we were doing all of these "smart grid" investments, nonetheless.
Is there a case to be made that all those investments, as you said, smart meters at 70%, penetration now, all of the IT and OT infrastructure, all the DER management systems, all these different things that got implemented to varying degrees, that it turns out now we have the capability to leverage them where we didn't before, or at least leverage them better where we didn't before? Or is it more like, "Actually we're using them for exactly the things that we were intending to use them for, and now it just happens we have a new set of tools that we can do more with."
David Groarke: It's a really good question. I think the short answer is that a lot of the promises of, let's say the first wave of digital infrastructure, didn't really prove out in the US. I mean just the cost of infrastructure needed to deliver power is nearly equal to the cost of generating power itself, right?
Shayle Kann: Right. If the point was to reduce T&D costs, we failed.
David Groarke: We failed. And not only that. OpEx costs are up about 14% a year and there's been a host of other challenges that the sector is going through, but I think this proving ground is a long time coming. What's happened though, I think, is that AI has been doing press-ups in the background, and that's the interesting thing. Algorithms have got better. They can do more tasks. They're more efficient. We have all that training data, that first round of investment, and that's multimodal data. It's energy, electrical, customer, weather and gasses, visual text, a whole host of data.
So that training data, those advances in the algorithms, and I think that the solution decline, costs decline where vendors can leverage open source tools like TensorFlow or PyTorch and develop applications quickly, I think the cost to innovate has come down, whereas let's say in that last round of investment, it was generally large platforms. It was all communications infrastructure and hardware. I don't think the original investments played out, but I think that is exactly why AI is interesting in the sector right now. Low cost solutions with high ROIs is what the name of the game of the sector is now.
Shayle Kann: I'll note that you said AI has been doing press-ups in the background, and I just learned that press-ups is Irish for push-ups, or maybe push-ups are American for press-ups?
David Groarke: Let's go with the latter. Yeah.
Shayle Kann: Yeah, sure.
David Groarke: Push-ups, press-ups, yeah, and pull-ups even, right? But it's definitely been working out.
Shayle Kann: We can all agree on pull-ups, yeah. All right. So I think it's probably fairly self-evident why there's some opportunity. We have to define what that opportunity is, but some opportunity for AI in the power sector. It's an enormously complex system with an enormous amount of data and incredibly challenging optimizations alongside that, and so there must be opportunities somewhere in there. But before we get into those use cases, let's talk about why it's actually going to be tough, and in some ways why that first wave, as you said, hasn't played out as expected. Why is the electricity sector a hard one? Why is it not the first sector? There are lots of sectors where an AI is completely transformative already today. I think of the legal profession for example. Why is electricity probably not one of those?
David Groarke: Right. Yeah. I think it owes... The primary reason why we're not on a path towards full automation, and there's been a spade of use cases launched as just modeling grid physics accurately, is incredibly difficult for an algorithm. So solutions on power flow obviously need to take into account Ohm's law and Kirchhoff's law, and accurately predict or make real-time decisions. So there is a limit to where AIs can be deployed currently for real reasons. I think, just the complexity of the system. If you look at a Sankey of any utility and you've got the data sources and you've got the data management platforms and the visualization platforms, they are some of the most complex diagrams that you could witness.
So it's not an easy operating environment for solution providers or for solutions to be embedded. And look, I think there's the typical industry issues around just rate basing new technologies, but more broadly just for some of these use cases, the data's not available, Shayle, and it's not frequent enough so we don't have the millisecond granularity that's needed for some of these use cases. That makes it all a little bit difficult. I think it's also, there's a torturous sales cycles for start-ups which can be off-putting after a couple of years. I mean, people tend to give up.
Shayle Kann: Torturous is a literal word in some cases.
David Groarke: Right. Yeah. And that's not helpful to innovation or to start-ups. What you're seeing is incremental change by the grid giants over time and a few use cases and vendors making it through the ranks. But I think all of that, I think the complexity, I think the cybersecurity components, I think just the grid physics, I think all of that makes it complex. And I think when we talk about use cases you'll see that some of the use cases play out across areas that don't touch on those grid physics.
Shayle Kann: Yeah. I think it's this enormous opportunity meets incredibly high barrier to entry problem that basically everything in energy tends to face.
David Groarke: Right. And just to add to that complexity, it's also, there's so many problems within the sector around folks retiring. So your 50% of the workforce is going to retire in the next 10 years. You can see that happening right now, so you have this kind of field technicians are leaving, and there's other priorities. Building out transmission infrastructure, different capital programs and so on. So utilities are having to balance their IT investments with some very weighty challenges that they've been given, so there's a juggling act going on too.
Shayle Kann: Let's talk for just one minute about what we actually mean by AI. I think the term gets thrown around a lot. It has gotten thrown around a lot and it means different things to different people. There's the LLM ChatGPT version of it, and all this generative AI is a new phenomenon, but AI interspersed with machine learning and other tools is all over the place. As you think about it, specifically in the power sector, what are the subcategories of AI that we should be thinking most about?
David Groarke: Yeah, that's a good question, and that's the very start of a conversation with a utility or with any stakeholder in this industry. Defining AI, it's an interesting question in terms of how you frame it. I think one way that we've been looking at it is defining it through a set of capabilities so you can understand it from a business perspective, so looking at machine learning and predictive analytics. These are algorithms that detect patterns or can make decisions. That's one set of solutions. Computer vision, so these may be cameras that interpret or understand the visual world, right? Infrared cameras and so on. Another set. And natural language processing, interpreting text, voice, human language, robotics, anything that's doing a task in a robotic nature that a human would do, so perimeter security by a robot would be classified as AI.
I think areas like digital twins, so these are virtual replicas that move beyond things like anomaly detection into scenarios and decision-making. You mentioned LLMs. We're seeing some application of LLMs across the industry, but usually at the enterprise level around regulatory documents, around generating text or guidance. Less on the actual power sector side of the operation self itself. I think we look at distributed AI, Shayle, which is embedding that intelligence at the edge. So in the sector, remote substations that mightn't have strong communications with HQ. That's a big component.
I think there's less mature parts of AI in the sector too. There's an emerging area I think that the sector's really interested in called Explainable AI, which is really explaining how a decision was made. I think that's really important from a regulatory perspective as we move towards automation. But really it's just a set of capabilities, and these capabilities are embedded in existing applications. They're in new applications and these are the things that have been doing the pull-ups, Shayle. These have got better, they've got cheaper. Utilities have got more comfortable with them and vendors are using them more and more.
Shayle Kann: So you started to get into some applications, but I asked you to pick three actual applications, real use cases of AI in the power sector that you think are real and immediate and interesting. So let's talk about those. Pick your number one.
David Groarke: Okay. Well, I think, to look at something contained and something that's really new, that's it been in rate cases in the last 12 months across the country and for good reason. So, wildfire is obviously a frequent kind of event now for utilities, particularly on the West Coast and PG&E in 2022 had a 1.3 billion rate case for the wildfires that happened that year over a three-year period. And so anything that plays into that space is going to be a welcome event for utilities. Anything that helps vegetation management, which utilities spend billions a year on collectively, is interesting.
So AI for wildfire management. Very discrete area and we're seeing a lot of deployments in that. So what you have there, you've got new data. You've got cameras that are in fixed positions and they're monitoring images of vegetation. You've got drones that may be taking images of density of growth and so on. You've got historical GIS data, you've got lidar, which is obviously 3D modeling. So you have these new sensors and data is being deployed and you have external data that's used in the mix like satellite imagery, weather data.
And you combine all this data together when you're collecting these high resolution images and you're predicting the vector of growth, the vegetation, or you're seeing changes over time or positioning of vegetation in relation to infrastructure. You can do some pretty cool predictive analytics. And I think what we're seeing there is that you can better deploy field crew, your existing maintenance personnel and so on, and that sees immediate results. So I think why that's interesting, just from an AI perspective, it's a really discrete use case. You've got new sensors, you've got better algorithms, and-
Shayle Kann: It doesn't really interfere with core operations. I mean it's tied to core operations, but I see why the discreteness of it is valuable here because you can imagine saying, "Okay, well, this isn't like grid reliability, short of the wildfire itself impacting grid reliability, isn't going to be affected here."
David Groarke: Yeah. And it's also got a broader benefit. So the PG&E rate case. What they ended up building was this fire potential index with a whole series of partners. They used all that data you mentioned, and they used 30 years of historical data and they're sampling that several times a day, and that gives them a pretty good... Not real time, but a pretty accurate insight into potential threats. And it's relatively low cost. These are SaaS platforms with some sensors running to the millions over years of agreements. That's where the high value comes from, Shayle. But, yeah, discrete. Doesn't touch operations, not overly political, and can roll it out pretty quickly.
Shayle Kann: All right. So that's discrete, new data, new data sources sort of fits the mold for things that could apply new technology, or in this case AI of various stripes quickly.
David Groarke: Right.
Shayle Kann: What's number two?
David Groarke: Number two. I mean if we look at the customer side of things, which... And we'll get to some of the use cases on the power flow side, but customer propensity modeling, things like EV detection. What's really been interesting is, over the last 10 or 15 years, utilities have really waxed lyrical about owning the customer relationship, and monetizing all of this AMI data. It's a fixture as a panel at events and so on. I think that's actually happening. So in terms of how propensity models working for utilities at the moment, they have the AMI infrastructure, we said, that's over 70% deployed. They have obviously their customer information systems, which are all the records of the customer and their interactions and so on over time.
And then they have external data. So this will be data like socioeconomic data or weather data or property information, size and type. And what a utility can do with that is some interesting propositions for customers. You can perform non-intrusive load monitoring, which basically disaggregates the total energy signal of a smart meter, and you can look at various characteristics of that using machine models and get something like an EV charging signature and say, "Okay, we've detected an EV." Maybe you compare that detection with some other data and validate that an EV has been charged. That's actually really important for utility because that changes the nature of the customer relationship. You can be very direct.
You can do clustering and segmentation and get customers on new tariffs and own a little bit more of the relationship on the EV side. And that whole propensity modeling piece around clustering and segmentation, just using all of that data, utilities can be more purposeful about how they plant EV charging infrastructure based off those decisions, but also their grid infrastructure. So that non-intrusive load monitoring using external data, identifying consumption and selling new products and services is happening now. And that's live at utilities. Just like the wildfire example, there's live at Duke and Southern California Edison and so on, these EV detection segmentation use cases. I think that's pretty interesting. It's real value from the smart meters that we talked about earlier.
Shayle Kann: Yeah, so maybe what's distinct about that from the wildfire use cases, it's not exactly new data sources. That AMI data has been around for a while as have all the other sources of data that you described. It's maybe the capability to weave them all together and the desire to do something with it, and particularly the arrival of EVs en masse, at least for some utilities, maybe catalyzes some actual action on this.
David Groarke: Yeah, I think so. And there's upstream benefits for how you plan your grid and transformers, and you look at rolling out new infrastructure and so on. It's got benefits both sides of the meter, which is always appealing to utility. And it's about owning and transforming that customer relation a little bit because there's more you can do with that. You can transform how you communicate with the customer through more automated personalized messages and just communicate and own that relationship a bit.
We all know our relationship with the utilities is the only time we think about the utilities is when we get a bill, but this is a little different. And utilities are communicating more frequently with their customers and that. So, yeah, exactly, Shayle, that's why it's interesting. Again, somewhat discrete, right? Not dealing with operations or power flow or any of those complex matters as yet.
Shayle Kann: Right. Okay. Well power flow, you mentioned, we'll get to one of those. For number three, can we talk about something that is in the sort of core operations world of power flows?
David Groarke: Yeah, that is two here. I think in core operations, the first one I mention, because this is highly important for utilities, right? Substation, asset management, it doesn't light everyone's world on fire, but there's huge dollars associated with this. You've got vibration sensors, partial discharge sensors, gas sensors, temperature sensors. You've got inspection drones and robots and they're looking for wear and tear on equipment, they're looking at SF6 gasses, they're looking at insulation breakdowns and so on. And what's interesting is, again, the algorithms have got so much better in the past five years, so these computer vision platforms, they're analyzing video feeds from fixed cameras and they're able to detect corrosion on these assets.
The machine learning platforms, which can be built on some of these open-source tools and then made proprietary, are able to look at some predictive maintenance strategies, build it into existing digital twin software where you're moving beyond anomaly detection into digital replicas and scenarios and so on. I think that's a huge value use case for utilities. It can't be understated. You can reduce downtime of some of these critical components by like 30, 50%. You can extend the life of transformers. They cost anywhere from 100,000 to a million. They take forever to be delivered these days. I think all of that, that's pretty critical work for utilities. And the whole system space here and the point applications and the integration, utilities have got really good at this.
This is where, when we talk about the proving ground of AI, it mightn't be cool to somebody from outside the industry, but I think those types of use cases are pretty interesting, particularly at the substation level. Again, though, it's complex. There's lots of protocols, IEC 61850. There's lots of complexity in here, but this is, I think, where we've seen the most maturity in IT, OT, AI type work. I don't know if you want to touch on the power flow too, piece, Shayle. I think, yeah, right, quickly. So let's say transmission capacity optimization is an interesting area. You've got lines that you're using to get renewables from up north down south, wherever the low pocket may be.
And in the past, to look at the level of congestion or the heating or the sag of the line which causes a traffic jam effectively, utilities used to use traditional static grading. That was based on consumptions and environmental conditions and some external weather. What they're doing now is moving to using near real-time data. So they're looking at the current capacity of overhead lines, and I think these are live, these solutions. They're able to deploy non-intrusive centers, so you've got lidar solutions that are monitoring the line. These are video cameras.
You could be using mechanical data, looking at vibration centers, and you're losing real-time weather data. And that really gives you better control over how you write power and it helps remove the bottlenecks, relieve congestion, maximizes current infrastructure. The business cases here are really strong. Perhaps the FERC requirements and the regulatory direction are still emerging, but I think an area like this, this is right in AI's wheelhouse. It's non-intrusive and it can add pretty immediate value to increase transmission efficiency, for example. So that's pretty discrete and I think a pretty impactful area of AI right now.
Shayle Kann:Yeah, okay. So hopefully we've convinced ourselves and everybody who's listening that these things, they're not as obviously mind-blowing as all the generative AI stuff is today. But for everyone that we mentioned there are probably 10 that we didn't mention, right? There's just a million discrete little opportunities to leverage AI and new techniques and new tools and new data sets to improve this system.
The other question though, of course, especially if you're in the world of start-ups and venture capital and so on, is like, "Okay, but who's doing all this?" You alluded to this before in the first wave. A lot of what ended up happening, it was Schneider and Eaton and GE and Siemens and ABB and the typical large utility vendors who ended up rolling out most of the new technology. There were exceptions, but that tends to be how it goes in this sector. As you see this new wave of innovation coming, who are the suppliers delivering the new solutions? And is it any different from how it has been historically?
David Groarke: That's a great question. I think it is a little different, Shayle, and I mentioned that the cost to develop these solutions has kind of collapsed a little bit with these open source libraries and frameworks and packages. And we were purposeful in this work to look beyond the conglomerates and the grid giants to really get a temperature check on the market.
What we found was a series of start-ups here looking at discrete problems and across all of the areas where we mentioned it's the most pressing. Even across the use cases we mentioned there's a series of start-ups, so there's a lot of activity. We looked at, I think, 350 of the slowest deployments since 2001, and we had a focus on start-ups. And I think what we found was that start-ups received 1.5 billion from 80 rounds of funding related to those deployments since 2021. That's a pretty sizable capital inflow.
Shayle Kann: Well, wait, just to be clear, that's the venture funding that went into those companies? Or that's the money that came from customers?
David Groarke: Venture capital funding that went into start-ups since 2021.
Shayle Kann: So I guess what that tells us is that there are start-ups being funded to take on these challenges. Doesn't yet tell us if they will win.
David Groarke: No, that is... Yes. I think the journey of a start-up in this space might look very different than maybe other markets, Shayle. But, yeah, it does not tell us that they will win, but it does tell us that there's a healthy venture market. There are start-ups. There is data, and there is something different about this point in time in terms of access to data. That is not to discount that ABB, Siemens, Schneider Electric, Oracle, aren't doing incremental changes to their products and picking up start-ups along the way. I think what's more interesting is where the start-ups are occurring, and they are more so on the grid edge.
I think most of the start-ups we found were playing in the DER integration space or EV charging management place. We saw some start-ups in the enterprise type of use case space, even looking at regulatory documents with LLMs for example. As you go down the list from the grid edge and the customer into core utility operations, that becomes more grid-joint focused around fault and outage management detection and so on. But where there's change or urgency for solutions, there's markets being created.
They're typically organized around traditional utility imperatives, Shayle. That's what we found. I can't say that there is an enormous new market emerging because of AI. As a result I think AI is kind of riding the wave within the sector. Obviously you need policy changes and business model changes and whatnot for complete reinvention in the sector. But there's quite a few start-ups, and in the deployments we looked at, there's successful use cases that are scaling across the US.
Shayle Kann:I guess final question, if we take a slightly longer-term view here, the promise that lots of folks have gotten excited about, generally people who are new to the industry but are in the tech world, look at electricity and at some point get very excited about this idea of full optimization and automation of the electricity network. They then run in hard into the brick wall of reality at some point as they're trying to figure out how to actually implement that full automation. You could take a few different views today as to how that plays out. One is that, look, this is a pipe dream and let's be realistic, it's never going to happen.
The second is, maybe it will happen but it's going to happen via a series of incremental changes. There's no blanket solution who comes in and automates the entire system from generation to the customer, but we're doing it piece by piece now, and maybe thanks to these new technologies we could do it faster. The third is actually, yes, I think something will fundamentally change and the opportunity will be there to, I don't want to say rip and replace, but execute a fundamental transformation of how electricity is delivered in a relatively short period of time. Of those three options, or a fourth one that I haven't thought of, where do you sit?
David Groarke: Right. Yeah, good question. I think there's possible and preferred and potential futures across all three, and they're all beholden to different characteristics. I certainly think that it's potentially possible. We're a few years away from being a few years away from that though, so I think the timeframe is really important. I think if there was the right investment and the right technologies, we can talk about some of the challenges to get there. Your third option is possible. It could be a reality. I think number two, I think the incremental change over time will lead us to a system that eventually becomes very automated with the support of regulatory infrastructure and the support of proven technologies through rate cases. And so I think we'll get there.
But, Shayle, it's really important to underline in this that the data right now is not available for, let's say, real-time decision-making across the grid. What we have is AMI, which is minutes to hours. We have SCADA, which is seconds to minutes, and then we have PMUs, which are kind of millisecond and frequency and granularity. I mean, for that future you're talking about, what we'd need is 100% nodal determination, and you need a lot to get there. I mean, right now most of the work is on post-event analysis, after the fact model validation. And I think to get there, it needs a lot of investment, and that's where your third option would come in.
I think that things that need to happen there are quite large in terms of deploying PMUs and having better interaction between the digital and physical layer of the grid, taking into account Ohm's law, as we said, and I think that regulatory innovation. I think even communications infrastructure would need to greatly increase along with those PMU deployments. I think we talked about explainable AI. I think AI would have to explain how a decision was made to a regulator. It couldn't be fully automated.
I think there's so many steps to get there, but I think even the few use cases we touched upon, they're pretty significant jumps for how the sector operates today. And it mightn't be like the tech industry where you could see a huge leap and it's phenomenal and you can chart the growth to something. I don't think that this counts from the level of transformation that's actually happening right now. It mightn't be front page news of fast company, though, but it's still interesting. But, yeah, I'm going to stick with my answer being the second, incremental change, I think, Shayle, is where we'll end up.
Shayle Kann: It's probably the obvious answer, but it would be interesting if a few years from a few years from now, something really turns over. David, thank you so much for doing this. Really appreciate the time.
David Groarke: Yeah, of course. Great. Thanks, Shayle.
