When grid planners quietly admit “we could have a problem,” you know something has shifted. The second POWERGEN keynote in San Antonio did exactly that, turning a technical conference into a warning flare for anyone who depends on reliable electricity.
Behind the polished slides, the message was blunt: rising energy demand, surging data center loads and uneven renewable integration are converging faster than the wires and transformers that carry power can be reinforced. The future grid, delegates heard, will be decided as much in policy rooms and permitting offices as in control centers.
Grid challenges at POWERGEN: stress, AI and shifting risk
The afternoon session on the future of power generation brought leaders from ERCOT, PJM and SPP onto one stage, mirroring debates that now dominate planning meetings across North America. According to coverage in Power Engineering, the keynote framed a stark outlook: load curves bending upward, project queues stretching for years, and a transmission network struggling to keep pace.

Executives described how AI, electrified industry and extreme weather are reshaping the future grid. In some regions, demand forecasts are being revised upward by several gigawatts within a few years, largely from hyperscale data centers that expect 24/7 supply. That combination of speed and scale is pulling infrastructure resilience to the center of strategic discussions.
Market reforms and capacity accreditation under pressure
The keynote dug into how market rules, rather than physics alone, decide whether megawatts appear when they are needed. Panelists referenced ongoing efforts to “rebalance risk” in capacity markets, echoing discussions reported in industry analyses. With weather-dependent resources now providing a large share of capacity in some territories, system operators are revisiting how much firm contribution a wind farm or solar plant can reliably claim.
Capacity accreditation is evolving from simple nameplate figures to performance-based metrics that consider multi-day weather events and correlated outages. This shift affects investment decisions directly, tipping the scales between new combined-cycle gas projects, multi-hour battery storage, and grid-enhancing technologies that squeeze more capacity from existing lines.
Technology advancements: from microgrids to multi-hour storage
Between the sober warnings, the keynote also highlighted pathways through the bottleneck. Speakers pointed to on-site generation, microgrids and flexible assets as pressure valves for congested systems, a theme echoed by technical sessions such as “From Grid-Lock to Microgrid.” Companies like ACS have framed this as a practical blueprint for an agile, resilient energy future, as described in recent briefings.
Technologies on the table included grid-scale batteries in the 100–300 MW range with four or more hours of storage, fast-ramping gas turbines prepared for future hydrogen blending, and advanced inverters that treat solar and wind plants as active grid-support assets. Together, they promise to turn intermittent electrons into dependable megawatt-hours, provided market signals reward that flexibility.
Renewable integration and hidden limits of the network
Behind the expansion of wind and solar lies a quieter limit: the hosting capacity of the existing transmission and distribution network. The keynote revisited how queues filled with gigawatts of proposed projects do not necessarily translate into steel in the ground. Experiences shared at related sessions and reported in industry forums show developers waiting years for interconnection studies and network reinforcements.
That delay is more than an investment headache. It slows the decarbonisation timeline and keeps older, higher-emitting plants running longer than planners would prefer. As climate scientists at institutions such as the National Renewable Energy Laboratory frequently stress, each year of delay narrows the carbon budget window that separates manageable warming from more severe ecosystem disruption.
Energy policy, markets and the economics of the future grid
Policy threads ran through every part of the keynote. Delegates heard how permitting timelines for new lines can outlast construction times by a factor of two or three, turning transmission into the slowest component of the decarbonisation puzzle. Reporting around the event, including coverage in NewsBreak, underlined how that mismatch is now treated as a strategic risk.
Investment signals are shifting too. Where a decade ago attention sat firmly on levelised cost of energy for individual plants, the conversation now tracks system-wide costs: congestion rents, curtailment of surplus solar, and the price of keeping spinning reserves ready for sudden ramps. The keynote suggested that regulators and market designers must align tariffs, capacity markets and ancillary services to value grid support, not only raw energy.
POWERGEN keynote as a snapshot of industry direction
The second powergen keynote did more than diagnose problems. It formed part of a wider series that, according to the official program, tackles grid stress, AI load growth and project delivery together rather than in isolation. That joined-up framing mirrors a growing recognition that climate policy, industrial strategy and digitalisation are converging.
Events like POWERGEN’s “Shaping Tomorrow’s Energy Landscape” call for content have attracted utilities, independent generators and large energy users who once occupied separate conference tracks. Their shared concern is not only compliance with emissions targets, but the practical ability to connect new capacity fast enough to meet surging load.
Implications for decarbonisation and what comes next
What does this mean beyond the convention center walls? For a data center operator in Texas, a steel mill in the Midwest, or a coastal city planning heatwave resilience, the keynote messages translate into practical questions. How secure is local supply as electrification accelerates, and which investments can reduce exposure to congestion or outages?
Climate research, from the IPCC to regional modelling labs, indicates that resilient, low-carbon grids will depend on both centralised assets and distributed solutions. The keynote’s focus on shared responsibility suggests an emerging toolkit for large users and communities willing to participate in that transformation.
- On-site and community-scale projects can ease local constraints through solar, batteries and demand response.
- Flexible demand from industries and buildings can shift consumption away from peak stress periods.
- Engagement in energy policy helps align planning rules, permitting and market design with decarbonisation goals.
- Long-term contracts for low-carbon supply provide revenue stability for new projects and visibility for planners.
Researchers often describe this as moving from a one-way, fossil-fuelled system to a living infrastructure that responds to weather, ecosystems and human needs together. The second keynote at POWERGEN, with its blend of warning and opportunity, made that shift feel less like an abstract strategy and more like an urgent construction site.
Why did the POWERGEN keynote focus so much on AI and data centers?
Speakers highlighted AI and data centers because they drive very fast, very large load increases that are difficult for traditional planning models to accommodate. A single hyperscale facility can require hundreds of megawatts of firm capacity, operating around the clock, which stresses both generation and transmission and reshapes local grid planning assumptions.
How do transmission constraints affect renewable integration?
When transmission capacity does not expand quickly enough, new solar and wind projects face delays or curtailment. They may receive interconnection approvals years after initial planning, or be limited in how much power they can export. This slows decarbonisation, increases congestion costs, and sometimes forces system operators to keep older fossil plants running longer to maintain reliability.
What role can microgrids play in easing grid challenges?
Microgrids with on-site generation and storage can support local reliability during grid stress, reduce peak demand, and integrate more renewable energy near the point of use. By doing so, they lower pressure on transmission and distribution networks, and provide resilience for critical facilities such as hospitals, water treatment plants and data centers during extreme weather events.
Why are capacity accreditation rules being revised?
Traditional capacity rules were designed around predictable, fuel-based plants. As wind, solar and batteries take a larger share, system operators need methods that reflect performance under stressed conditions, such as heatwaves or low-wind periods. Updated accreditation aims to reward resources that can reliably deliver during those events, guiding investment toward technologies and configurations that truly support reliability.

While POWERGEN does not set policy directly, it brings together grid operators, regulators, developers and large users in one forum. The discussions, such as those described in reports like Aging energy grid meets explosive demand, inform regulatory dockets, utility resource plans and corporate strategies. Over time, these shared insights can shape how rules, incentives and investments evolve for the power sector.
