Fifteen years. That’s how long I’ve been navigating the ever-evolving currents of the energy sector. I still remember the first time I walked into PowerGen back in 2010. Back then, the energy world felt like a fortress of gas turbines, grid-scale generators, and legacy OEMs—each showcasing their industrial muscle. That memory has stayed with me—part nostalgia, part benchmark for how far we’ve come.
This year, PowerGen 2025 in Dallas felt different—leaner in scale but richer in substance. It reflected an industry at a tipping point, no longer just looking to innovate, but being compelled to. With the climate clock ticking, AI reshaping operations, and data centers emerging as energy titans, the power sector is undergoing a dramatic shift.
Here’s what I saw, heard, and felt on the ground at PowerGen 2025—an event that served more as a mirror to our industry’s future than a mere exhibition.
Walking Into the New Era of PowerGen
The first thing that hit me? The floor looked… smaller. Gone were the lavish double-decker booths from global OEMs. Major turbine players and service providers had noticeably scaled back—signaling industry-wide belt-tightening, strategic refocus, or both.
The global power generation market is shifting toward greater fragmentation, with investments increasingly split between centralized fossil-fuel plants and decentralized energy resources (DERs) such as solar, battery storage, and microgrids.
But what PowerGen lacked in showy scale, it made up for in purpose. The spotlight had shifted—from size to substance, from steel to software.
From Wrenches to Algorithms: Technology Takes the Lead
Technology didn’t just join the party this year—it stole the show.
NVIDIA was everywhere—from keynote panels to technical workshops—signalling that AI is no longer the future of energy; it’s the present. Their presence wasn’t just symbolic. NVIDIA announced that over 25 utilities and grid operators are now piloting its platforms for operational optimization, using models that can process up to 1 terabyte of real-time data per day from sensors and SCADA systems.
Digital twin adoption is surging, with the global market expected to hit $137 billion by 2030 (Allied Market Research). Companies like GE Vernova and Siemens Energy are embedding AI into everything—from combustion tuning to outage prediction.
But the real game-changer? Agentic AI in nuclear power. In a powerful session hosted by EPRI titled “Shaping the Future of AI and Electric Power,” AI was shown managing fault trees, stress models, and control logic with a level of autonomy once unthinkable. One pilot project in the Midwest cut unplanned downtime by 28% in its first year.
Companies like Hexagon and Prometheus Group showcased tools turning drone imagery and sensor feeds into predictive maintenance gold. These platforms are shaving O&M costs by 20–35% and giving operators a new superpower: foresight.
Keynote Highlights: A Sector Redefined by Data and Demand
1. Data Centers: The New Titans of Load Growth
The biggest surprise for many? The raw scale of energy demand coming from data centers. One stat still echoes in my mind: by 2030, data centers could consume 5–8% of global electricity, according to the IEA—up from just 1–2% a decade ago.
In the U.S. alone, AI data center electricity demand is forecast to reach 390 TWh by 2030—equivalent to the entire annual consumption of California.
Executives from NVIDIA, Duke Energy, and Compass Datacenters didn’t mince words. AI workloads are pushing traditional grid planning to its limits. Marc Spieler from NVIDIA said it best:
“AI is the new industrial process—one that consumes electrons to generate intelligence.”
In Arizona, a state with four of the top ten fastest-growing data center hubs, utility regulators are scrambling to greenlight new peaker plants and upgrade transmission lines to meet the surge—most of it coming from hyperscale AI deployments.
2. Gas Turbines: From Sunset Tech to Clean Energy Bridge
While it’s tempting to write off gas turbines as yesterday’s tech, PowerGen told a different story. The session “The Role of Gas Turbines in the Clean Energy Transition” was packed—and for good reason.
Hydrogen-blending pilots are no longer hypothetical. GE shared that its HA turbines have already clocked over 1 million fired hours, with hydrogen blends of 30–50% operational in Japan and the Netherlands. Mitsubishi Power aims for full 100% hydrogen combustion capability by 2035, and its U.S. operations are expanding in tandem.
Yet challenges persist. Lead times for F-class turbines have doubled since 2020, now averaging 20–24 months. That’s prompting manufacturers to scale U.S.-based fabrication and testing. Siemens Energy’s Charlotte hub is undergoing a $300 million upgrade to accommodate next-gen turbine and hydrogen R&D.
One of the most technically impressive presentations came from PSM, whose FlameSheet™ retrofit combustion system delivers an industry-record 60% hydrogen fuel blend while maintaining single-digit NOx emissions. It was a must-attend session for any engineer interested in the practical future of decarbonizing gas turbines.
The Global Power Generation Market: A Sector in Flux
According to BloombergNEF, global investments in energy transition technologies surpassed $1.8 trillion in 2024, with over $500 billion directed toward renewables alone. These figures underscore a rapidly diversifying energy landscape—where capital is flowing not just into wind and solar, but also into technologies that support grid stability and reliability.
Amid this transition, the gas turbine market is seeing a surprising resurgence. Demand is surging—not shrinking—driven by the need for dispatchable power to backstop intermittent renewables and meet the explosive growth of data center electricity consumption.
The result? Massive order backlogs and extended lead times for the world’s top turbine manufacturers:
GE Vernova reported a total power backlog of approximately $80 billion as of early 2025, with $30–40 billion tied specifically to gas turbine projects.
Siemens Energy announced a record-breaking $131 billion backlog in 2024, with a large portion driven by gas turbine demand amid grid expansion efforts in North America, the Middle East, and Southeast Asia.
Mitsubishi Power held the #1 global market share for gas turbines in 2023, capturing 36% of the market. The company has received orders for over 120 units of its advanced J-series turbines, many of which are hydrogen-ready.
While many predicted gas turbines would fade in the energy transition, the opposite is proving true: they are being repositioned as essential “bridge technologies,” enabling a smoother shift toward net-zero while maintaining grid resilience.
Innovation in the Aisles: Generators, Drones, and the Future Grid
The show floor, while more compact, pulsed with innovation. Wärtsilä and Caterpillar debuted gensets with ultra-low NOx emissions, designed for microgrid resiliency and black start capability. Asian entrants—particularly from South Korea and China—highlighted affordable modular generation systems.
But the real buzz was software. Startups like Hexagon drew crowds with AI-powered drones now used by over 30 U.S. utilities for real-time substation and tower inspections. Meanwhile, Prometheus Group’s asset intelligence platform lets engineers simulate failures, dispatch crews, and generate real-time work orders—all from one interface.
Challenges on the Horizon: Can PowerGen Regain Its Momentum?
There’s no sugarcoating it—PowerGen 2025 didn’t match the grandeur of its pre-pandemic editions. International participation was thin, and several stalwart exhibitors were absent. Budget constraints? Perhaps. A strategic pivot toward virtual engagement? Likely.
And yet, the heart of the event—the conversations—was very much alive. The dialogues around hydrogen, AI, decentralized grids, and energy equity weren’t just technical; they were existential.
The Takeaway: Energy’s Next Chapter is Collaborative
What stayed with me wasn’t just the gadgets or keynote slides. It was the collaborative spirit I witnessed.
Gone are the days when OEMs, utilities, and tech firms worked in silos. Everyone—from grid planners to AI engineers—is realizing that the energy transition is not a solo act. As one speaker eloquently put it:
“This isn’t a revolution—it’s a symphony. And everyone has to play in tune.”
Final Thoughts: From Turbines to Terabytes
PowerGen 2025 felt like a time capsule and a telescope. It reminded me where we came from and showed me glimpses of where we’re heading. It wasn’t perfect—but it was powerful.
To those navigating this shifting energy landscape—whether you’re a veteran like me or a newcomer just getting your footing—this much is clear: the grid of the future won’t just be stronger or cleaner. It will be smarter. And we must be too.
Until next year, PowerGen.
