Vistra (VST) — moat facet

The scarce thing in American power is not equipment. It is a place on the grid, and Vistra's 44,000 megawatts are already through the queue.

The scarce thing in American power is not equipment. It is a place on the grid, and every one of these megawatts already has one.

Adding a new power plant means joining an interconnection queue, and the queue has become the binding constraint across every major market. Studies, upgrades, cost allocation and construction take years, and the queue is full of projects that will never be built. Meanwhile ERCOT is managing about 83,707 megawatts of peak demand for roughly 27 million Texas customers1 and PJM about 160,709 megawatts for about 67 million people2, with data centres, oil-field electrification and vehicle charging all pulling demand upward at once3.

Vistra's 44,000 megawatts4 are already through that process. Every one of them is connected, permitted, staffed and dispatchable today. That is worth something structurally different from owning the same equipment in a warehouse, and it is the reason a hyperscaler negotiating for firm power in 2026 talks to incumbents rather than to developers.

The two markets pay for it differently, which matters more than it sounds. ERCOT is energy-only: a generator earns from selling power and ancillary services and receives nothing for merely being available. PJM runs a capacity market that pays for availability separately from energy. The same physical asset therefore has a different revenue shape depending on which side of the boundary it sits, and Vistra's East segment collected $793 million of capacity revenue in 2025 offset by $566 million purchased5 — a revenue line the Texas segment does not have at all.

The honest framing is that this is an advantage with a clock on it. Interconnection queues are a temporary condition created by a demand surge meeting a slow process, and both markets are actively reforming their queues. Every reform that speeds up interconnection reduces the scarcity value of already being connected.

What is not temporary is the location. Vistra's fleet is concentrated in the two markets where American load growth is happening, and that was a decision made long before anybody was forecasting it.

Moat trajectory: Narrowing

The advantage exists because interconnection queues are long, and every market operator in the country is working on shortening them. It is a real and temporary edge, and the reforms are being made by people who do not want incumbents to earn it.

The number that tests this moat
Reported
Generation capacity in service
About 44,000 MW

All of it through an interconnection process that now takes years for a new entrant. The advantage is real and dated: it lasts as long as the queues do, and both ERCOT and PJM are reforming them.

Aspects of the moat
DIG DEEPER 01
ERCOT: An Energy-Only Market
Nobody is paid for being available, so a year's earnings arrive in a handful of hours the state has capped.
DIG DEEPER 02
PJM: Where Being Available Gets Paid
A retainer for existing, set at auction by a committee that answers to consumers rather than to generators.
DIG DEEPER 03
The Queue Is the Barrier to Entry
Competitors are not short of capital; they are short of a connection — and every reform shortens the advantage.
DIG DEEPER 04
Dispatchable, and Therefore Scarce
The grid has plenty of capacity and not enough power that runs at four in the morning.
⚠ Threats to the moat
⚠ THREAT 01
The State Sets the Ceiling
Texas decided by administrative vote how much a generator may earn in the hours that justify the whole investment.
⚠ THREAT 02
A Grid Event Can Cost a Year of Earnings
A generator that cannot generate during scarcity is not missing the upside — it is short, at the cap.
