Grid Queues Send Businesses Shopping for Bigger Onsite Turbines

Capstone Energy+ chief executive Vince Canino told Reuters that businesses unable to secure capacity from strained American utilities are ordering larger onsite generation blocks, shifting demand toward bigger self-supplied power systems.

Companies that cannot get the electricity they want from their local utility are increasingly deciding to make it themselves — and they are ordering bigger machines to do it. That is the message from Capstone Energy+ chief executive Vince Canino, who said in an interview with Reuters that rising demand for onsite power among businesses struggling to secure capacity from strained American utilities is pushing orders toward larger generation blocks.

The comment, reported by BNN Bloomberg, is a small window onto a large and increasingly awkward problem in North American electricity: the queue to connect to the grid has become long enough that a growing set of industrial and commercial buyers has stopped waiting in it.

What a "larger generation block" actually means

Onsite power — sometimes called distributed generation or behind-the-meter generation — is electricity produced at the place where it is consumed, rather than delivered over transmission and distribution lines from a central plant. Historically, much of it was backup: a diesel set that runs when the grid fails, or a small gas turbine trimming peak demand charges.

A "generation block" is the modular unit a customer buys. Vendors in this market typically sell in standardized increments and let customers stack them to reach the capacity they need. When a supplier says orders are moving toward larger blocks, it means buyers are no longer specifying enough capacity to keep the lights on in an outage. They are specifying enough to run the business.

That is a meaningful change in intent. Backup generation is an insurance product, bought reluctantly and sized to the minimum. Primary onsite generation is an infrastructure decision, bought because the alternative — a utility interconnection — is either unavailable, too slow, or too expensive to wait for. The size of the order is the tell.

Why the interconnection queue is doing the selling

Canino's framing puts the cause squarely on the utility side: customers are struggling to secure capacity. Two forces are colliding in the American grid at once. Demand is rising after two decades of near-flat load growth, driven by data centers, electrified industrial processes, transport charging and hotter summers. And the supply-side response — new generation, new transmission, new substations — runs on permitting and construction timelines measured in years.

The result is rationing by queue. A manufacturer that wants an additional block of firm capacity at an existing site may be told the upgrade depends on a substation project that has not been scheduled. A developer siting a new facility may find that the fastest path to power is not the nearest transmission line but a fenced yard full of turbines.

For the buyer, the calculation is not really about the cost of electricity per unit. It is about the cost of not having any. A plant that cannot expand, a data hall that cannot be energized, or a campus that cannot add a production line has a revenue problem that dwarfs the fuel bill. That is why onsite generation economics, which look unattractive on a simple per-kilowatt-hour comparison against utility tariffs, keep clearing the hurdle anyway.

Who wins and who is left holding the meter

The obvious beneficiaries are the equipment suppliers — turbine and engine manufacturers, packagers, switchgear and controls vendors, and the service firms that maintain the fleet once it is installed. Onsite generation is also an annuity business: machines sold today generate parts, monitoring and long-term service agreements for years afterward. Order mix shifting toward larger blocks lifts both the initial ticket and the eventual service base.

Fuel suppliers benefit too. Most onsite blocks of this type burn natural gas, sometimes biogas or a blend, which means each installation adds a pipeline customer and a durable demand point outside the power sector's own dispatch.

The party with the harder problem is the utility. Every large customer that self-supplies is a customer that stops paying for the shared network at the volume the rate base assumed. Fixed transmission and distribution costs do not fall when a factory installs turbines; they get spread across a smaller volume of billed energy. That is the classic utility death-spiral argument, and it has been theoretical for most of its history. It becomes less theoretical if the buyers doing the leaving are the largest loads on the system.

Regulators are the third actor. Interconnection reform, standby rates, exit fees and rules on who may build behind the meter are all live questions in multiple jurisdictions. How they are settled will determine whether the trend Canino describes is a temporary bridge during a capacity crunch or a structural reallocation of where electricity gets made.

What to watch from here

The useful measures are not headline demand statements but order-book detail. Watch for disclosure of average order size, backlog conversion, and the split between backup-duty and prime-duty applications — the second of those is where the margin and the service revenue live. Watch delivery lead times as well: in a market where every supplier is reporting strong demand, the binding constraint moves from customer appetite to turbine availability, and buyers start queuing for equipment much as they queued for interconnections.

Watch, too, whether the buyers broaden. If onsite orders remain concentrated in data centers, the trend is a subset of the artificial-intelligence buildout and will rise and fall with it. If manufacturers, hospitals, cold-chain operators and campuses are also sizing up, the shift is about the grid itself rather than any single end market.

Broader equity markets gave little away on the day the comments circulated. As of the last trade at 16:30 GMT on 24 August 2026, the S&P 500 tracker (NYSEARCA: SPY) stood at $764.95, down 0.10% from a previous close of $765.72, with the Nasdaq 100 tracker (NASDAQ: QQQ) at $708.88, off 0.64%, and the Dow tracker (NYSEARCA: DIA) at $533.94, up 0.32%. A tape that flat is a reminder that grid constraint is a slow-burning industrial story, not a one-session trade — its effects show up in capital budgets and order books long before they show up in an index.

The uncomfortable implication for policymakers is straightforward. When a supplier's customers respond to grid scarcity by buying more of their own generation rather than less, the market is signaling that it has priced in delay. Fixing the queue is the only thing that changes that signal.

Frequently asked questions

What did Capstone Energy+ actually say?

Chief executive Vince Canino told Reuters that demand for onsite power is rising among businesses that cannot secure capacity from strained American utilities, and that this demand is pushing customer orders toward larger generation blocks. He did not disclose specific order volumes or pricing in the reported remarks.

What is onsite power generation?

Onsite or behind-the-meter power is electricity produced at the location where it is consumed, rather than delivered over utility transmission and distribution lines. It ranges from small backup engines that run only during outages to full prime-duty installations sized to supply a facility's normal operating load continuously.

Why can't businesses get capacity from utilities?

Electricity demand is rising after years of flat growth, driven by data centers, industrial electrification and transport charging, while new generation, transmission and substation projects take years to permit and build. The gap creates interconnection queues, so some customers are told new capacity depends on infrastructure that is not yet scheduled.

What is a generation block?

A generation block is the standardized modular unit that onsite power suppliers sell. Customers stack multiple blocks to reach the capacity they need. When a supplier reports orders shifting to larger blocks, it indicates buyers are sizing systems to run operations rather than merely to survive a grid outage.

How does this affect utilities?

Large customers that self-supply reduce the volume of billed electricity across which fixed network costs are spread, which can pressure rates for remaining customers. Regulators are weighing responses including interconnection reform, standby rates and rules governing behind-the-meter generation, and those decisions will shape how far the trend runs.

What should investors watch next?

Order-book detail rather than demand rhetoric: average order size, backlog conversion, equipment lead times, and the split between backup-duty and prime-duty applications, since prime duty carries larger tickets and longer service revenue. Also watch whether buyers extend beyond data centers into manufacturing, healthcare and campus loads.
