New York Bets on 5 Gigawatts of New Nuclear, Vendor Unnamed
Albany wants 5 gigawatts of new nuclear a half-decade after Indian Point closed. No reactor design has been picked yet, and the choice between a large Westinghouse AP1000 and GE Vernova Hitachi's 300 MW…
Governor Kathy Hochul is pursuing 5 gigawatts of new nuclear capacity in New York, with at least 1 GW to be developed by the state-owned New York Power Authority and a separate 4 GW initiative, five years after the last reactor at Indian Point shut down; no reactor technology has been selected, though the Westinghouse AP1000 and the 300 MW BWRX-300 from GE Vernova Hitachi are the likeliest candidates.
Five years after the final reactor at Indian Point powered down, New York is trying to build back what it retired. Governor Kathy Hochul is pushing for 5 gigawatts of new nuclear generation in the state, with at least 1 GW to be developed by the New York Power Authority, the publicly owned utility, and a separate 4 GW initiative alongside it. What the state has not done is say what it intends to build.
That omission is the whole story. A gigawatt target is a political statement; a reactor model is a procurement decision, with a supply chain, a construction schedule and a cost curve attached to it. Until Albany names a technology, the 5 GW figure is a direction of travel rather than a project pipeline.
Two very different machines are in the running
As OilPrice notes, the likeliest candidates are the Westinghouse AP1000, a large conventional pressurized-water reactor, and the BWRX-300, a small modular boiling-water design from GE Vernova Hitachi rated at 300 megawatts.
They imply opposite strategies. The AP1000 concentrates enormous capacity on a single licensed site, which means fewer siting fights, fewer interconnection queues and one very large capital commitment that has to be financed before a single electron moves. The BWRX-300 spreads the same total across many smaller units that are meant to be built in series, with the cost savings coming from repetition rather than scale.
The arithmetic makes the contrast plain. On an illustrative basis, filling the separate 4 GW tranche entirely with 300 MW modules would take roughly 13 units, and the NYPA's 1 GW share alone would need three to four of them. Building the same 4 GW with large reactors is a matter of a handful of units on one or two sites. Neither path is obviously cheaper in advance. Large reactors carry the well-documented risk that a first-of-a-kind build overruns badly; small modular reactors carry the risk that the promised learning curve never arrives because the order book is too thin to generate one.
Why the order matters more than the megawatts
For a supplier, an order of this size is not simply revenue. It is the thing that justifies tooling, forging capacity, welder training and long-lead component slots. A state that commits to a fleet, rather than a demonstration unit, is offering the one thing the nuclear supply chain has lacked for a generation: repeatability.
That is why the vendor decision reaches well past the reactor island. A single build draws in heavy forgings, turbine generators, reactor coolant pumps, instrumentation and control systems, containment steel, cabling and construction labor at a scale that cannot be spun up in a quarter. Engineering and construction firms, specialty steel makers and nuclear-grade component fabricators all sit downstream of a decision Albany has not yet announced.
GE Vernova is the most directly exposed listed name mentioned in the discussion, through the GE Vernova Hitachi joint venture that markets the BWRX-300. The stock last traded at 941.95 in the session that closed on Fri, 04 Sep 2026, effectively flat on the day at +0.01%, after ranging between 939.32 and 959.00. That session was a soft one for the broader tape: the S&P 500 (SPY) closed at $770.19, down 0.39%, and the Dow 30 (DIA) closed at $534.08, down 0.53%, while the Nasdaq 100 (QQQ) edged up 0.18% to $718.96.
Westinghouse, the AP1000 vendor, is not publicly traded in its own right, which limits how directly investors can express a view on that outcome.
The clock is the constraint, not the ambition
Westinghouse, the AP1000 vendor, is not publicly traded in its own right, which limits how directly investors can express a view on that outcome.
Nuclear plants are not procured on the timetable of a governor's term. Between site selection, an application to the Nuclear Regulatory Commission, financing, long-lead component orders and construction, the gap between announcing a target and delivering firm output is measured in years, not seasons. Every month spent without a named technology is a month the licensing clock is not running.
The financing question is equally unresolved. Putting at least 1 GW inside the New York Power Authority is a deliberate choice: a public developer can borrow against a public balance sheet and take on a construction risk profile that private merchant developers, disciplined by equity markets, generally will not. It also means New York ratepayers and taxpayers, rather than shareholders, absorb the consequences if a build runs long. The structure of the separate 4 GW initiative — how much is public, how much is contracted, who eats overruns — is the detail that will determine whether the target is credible.
What the demand side is really asking for
The revived interest is not nostalgia. Retiring Indian Point removed a large block of generation that ran continuously and did not burn fossil fuel, and nothing with the same characteristics replaced it. Wind and solar are cheap but intermittent; storage shifts hours, not seasons. Meanwhile electricity demand growth — driven by data centers, electrified heating and transport — has turned round-the-clock, low-carbon capacity into a scarce commodity that states are now competing for.
That competition is itself a risk to New York's plan. If several states and several data-center developers chase the same reactor vendors, the same forging capacity and the same nuclear-qualified construction workforce at once, the constraint becomes delivery slots rather than money. Early movers get schedule certainty. Late movers get a place in a queue.
What to watch next
- The technology announcement. Naming AP1000 or BWRX-300 converts a target into a procurement and starts the regulatory clock.
- Site selection. Existing nuclear sites with grid connections and community familiarity are the fastest path; greenfield sites are the slowest.
- The financing structure. Who carries construction risk on the 4 GW tranche, and whether NYPA's at least 1 GW is funded before the rest.
- Order concentration. Whether New York buys a fleet in series or one unit at a time, which determines whether any cost learning is possible.
- Supply-chain signals. Long-lead forging and turbine orders are the earliest hard evidence that a project is real.
For now the honest read is that New York has stated an ambition of a scale that would make it one of the more consequential nuclear buyers in the country, without yet making the one decision that turns ambition into contracts. The vendors know it, the supply chain knows it, and the megawatt figures will stay theoretical until the design is named.

Frequently asked questions
How much nuclear capacity does New York want to build?
Governor Kathy Hochul is pursuing 5 gigawatts of new nuclear capacity in New York. At least 1 GW of that is to be developed by the New York Power Authority, the state's publicly owned utility, with a separate 4 GW initiative accounting for the balance. No individual project sites or in-service dates have been attached to those targets publicly.
Which reactor technology will New York use?
No technology has been announced. The two most likely candidates are the Westinghouse AP1000, a large conventional pressurized-water reactor, and the BWRX-300, a 300 megawatt small modular boiling-water reactor from GE Vernova Hitachi. Until a design is selected, licensing cannot begin and no supplier contracts can be placed, so the capacity target remains an ambition rather than a pipeline.
Why is New York returning to nuclear power now?
The last reactor at Indian Point shut down five years ago, removing a large block of generation that ran continuously without burning fossil fuel. Nothing with the same round-the-clock, low-carbon characteristics replaced it. With electricity demand rising, states are competing for firm generation that wind, solar and batteries cannot fully supply on their own.
Which listed company is most exposed to the decision?
GE Vernova, through the GE Vernova Hitachi joint venture that markets the BWRX-300, is the publicly traded name most directly tied to the outcome. Its shares last traded at 941.95, up 0.01% on the day, in the session that closed on Fri, 04 Sep 2026. Westinghouse, the AP1000 vendor, is not separately listed.
What is the difference between a large reactor and a small modular reactor?
A large reactor such as the AP1000 concentrates a great deal of capacity on one licensed site, meaning fewer siting and interconnection processes but a single very large capital commitment. A small modular reactor like the 300 MW BWRX-300 spreads the same output across many smaller units, aiming to cut costs through repeat manufacturing rather than sheer scale.
What should investors watch next in this story?
The technology selection is the key milestone, because it starts the Nuclear Regulatory Commission licensing clock and enables supplier contracts. After that, watch site selection, the financing structure of the 4 GW tranche, whether reactors are ordered as a fleet or one at a time, and early long-lead orders for forgings and turbine generators.
