The Power Certainty Premium: GPC Infrastructure CEO Jim Summers on Delivering Gas-Powered Compute at AI Scale

Reliability Is the Real Constraint

Summers evaluates every large-scale power decision against four pillars: legal, economic, sustainable, and reliable. In the current market, one dominates.

Reliability — defined not merely as uptime, but as certainty of project execution — has become the industry's most pressing problem.

"There's a lot of noise in the market," Summers says. "The question is whether a project is real; whether it can be delivered on time, and whether it can maintain multiple nines once it's operating."

Legal frameworks for behind-the-meter generation are largely settled. Economics matter, particularly across multi-year development cycles. Sustainability factors in, though in many cases it has been deferred behind more immediate concerns. Execution, by contrast, is now existential. Hyperscalers are no longer evaluating power sources alone: they are evaluating delivery credibility.

From Megawatts to Certainty, Speed, and Risk Transfer

Historically, data centers relied on utilities to supply three things together: energy, predictable timelines, and manageable risk. That bundle has broken down.

Utilities face long interconnection queues, uncertain delivery dates, and rising infrastructure costs. For developers, that uncertainty has created what industry observers and stakeholders are starting to call a "power certainty premium," i.e. a willingness to pay more for guaranteed timelines.

GPC's customers, Summers says, are no longer buying megawatts alone. They are buying speed to market, certainty of delivery, and risk transfer.

"Even if the timeline isn't shorter, they want a date certain," he notes. "Utilities often can't provide that today."

That evolution is driving demand for on-site, behind-the-meter generation, where developers control timelines and cost structures rather than waiting on grid expansion.

Supply Chain as the New Critical Path

Remove the grid and a new constraint appears: equipment availability.

For GPC, the primary gating factor is supply chain; specifically the "prime mover," the generation equipment itself.

Large industrial turbines now carry lead times exceeding five years. GPC favors smaller, more flexible systems: air-derivative turbines (including converted jet engines), reciprocating engines, and modular generation in the 100 MW to 1 GW range.

That approach creates optionality, but constraints remain. Transformers, switchgear, and other electrical components are in high demand. Permitting — air permits especially — and securing firm natural gas supply add further complexity.

Power delivery timelines are now governed as much by industrial logistics as by energy policy.

Natural Gas as a Permanent Layer, Not a Bridge

A year ago, behind-the-meter gas was commonly framed as a temporary bridge. That framing is disappearing.

Summers is unequivocal: on-site natural gas is becoming a permanent architectural layer in AI data center design.

"There are economic reasons why having load and power adjacent makes sense," he says. "About 10% of U.S. generation is already on-site — universities, hospitals, industrial facilities."

AI data centers are joining a long-established model. This doesn't displace the grid. It complements a broader mix that includes grid expansion, renewables, and nuclear. But for large AI workloads, on-site gas is emerging as a foundational component.

Why Batteries Are Now Non-Negotiable

AI workloads introduce a power challenge that average demand figures obscure. Instantaneous load can swing dramatically, ramping up or down within seconds. Traditional generation systems are not built for that volatility.

Batteries solve it. They buffer generation against load, absorbing rapid fluctuations and smoothing demand. Without them, those swings stress generators and erode reliability.

"They allow you to discharge from the battery instead of the generator," Summers says, "which extends equipment life and maintains reliability."

Gas provides the capacity. Batteries provide the control.

Rewriting the Risk Equation

Under the traditional utility model, operators have limited control over power costs. Tariffs are shaped by regulatory decisions, infrastructure investments, and commodity markets.

On-site generation changes that.

Developers take on capital and operational responsibility for their own infrastructure. In exchange, they shed exposure to utility build-out costs, infrastructure inflation, and interconnection delays. What remains is commodity risk — aka natural gas pricing.

Unlike utility tariffs, gas markets are liquid and hedgeable.

"It's like buying the cloth instead of the clothing," Summers says. "You now have the ability to manage that risk directly."

The Mobile PPA: Flexibility in a 20-Year Bet

To address long-term uncertainty, GPC has developed what it calls a mobile power purchase agreement.

Traditional models force a choice between short-term leases with high costs and long-term PPAs with little flexibility. The mobile PPA bridges that gap: costs are amortized over a long-term agreement, while equipment can be relocated to new sites, converted to backup power, or reassigned as grid capacity becomes available.

The goal is to prevent stranded assets in a market where demand, technology, and infrastructure are all in motion.

Waste Heat Capture: Efficiency Waiting on Adoption

Traditional power generation converts roughly 35 to 40 percent of input energy into electricity. The remainder escapes as heat.

That heat can be recaptured. In data centers, where cooling demand is constant, absorption chillers can convert waste heat into chilled water — turning a byproduct into a resource. Summers says the approach can push system efficiency toward 85 percent.

The obstacle is adoption. Waste heat capture adds complexity at a moment when operators are prioritizing speed. Water usage is a concern in some configurations. But Summers sees it as inevitable, drawing a parallel to the evolution of combined-cycle generation.

"Our belief is this will become the de facto standard," he says.

Misconceptions Are Fading — but Not Gone

Several early objections to behind-the-meter gas have largely dissolved. Regulatory frameworks are now in place. On-site gas infrastructure has proved more reliable than grid assumptions often allow. Hyperscalers are committing to gas as a long-term solution, not a stopgap.

One misconception persists: sustainability.

Summers argues that natural gas has done more than renewables to reduce emissions, primarily by displacing coal, and that on-site gas generation can produce fewer emissions than grid power in many regions.

It is a contested position, but one increasingly present in the industry's internal calculus.

The Bottom Line

The AI boom is no longer theoretical. It is a construction problem.

Power — delivered on time, at scale, with reliability — is the gating factor. Solutions that offer certainty, whether through on-site generation, flexible contracting, or integrated energy systems, are commanding a premium.

As Summers makes clear, the industry is no longer solving for megawatts. It is solving for execution.
