# Speed-to-Power for Data Centers: Where Firm Nuclear Fits
Published July 23, 2026 · Updated July 24, 2026 · By [Jamie Kloncz](https://rankshieldenergy.com/authors/jamie-kloncz), Founder, RankShield Energy

HELIX microreactor, concept render. RankShield Energy is at the pre-application stage; this depicts a design under development, not an operating facility. Speed-to-power is the time from choosing a data center site to having firm, around-the-clock electricity available to energize the load. It has become the governing variable in site selection because electricity demand from data centers is rising faster than the grid can connect new load. The useful question is not which source looks best in the abstract. It is what can actually be energized, and when.
The demand side is documented and the supply side is constrained by process. Lawrence Berkeley National Laboratory reported that U.S. data centers used about 176 TWh in 2023, roughly 4.4% of U.S. electricity, with a projected range of 325 to 580 TWh by 2028, or about 6.7% to 12.0% [[1]](#src-1), and the Department of Energy released that assessment as an evaluation of rising data center demand [[2]](#src-2). EIA now forecasts the strongest four-year growth in U.S. electricity demand since 2000, attributed substantially to data centers [[3]](#src-3). Meanwhile NERC reports that 13 of 23 assessment areas face resource adequacy challenges over the next decade [[9]](#src-9). Load is arriving faster than firm supply is being connected.
One scope note before anything else. This article does not compare what any option costs. There are no unit-cost figures here, no energy-rate figures, and no ranking of the options by expense, because cost is a separate analysis with its own assumptions and it is deliberately out of scope for this piece. What follows compares three things only: time to power, firmness, and the constraint that actually governs each route. RankShield Energy is a pre-applicant with the U.S. Nuclear Regulatory Commission, holding no license, permit, or design approval [[15]](#src-15), and the closing section states our position on this timeline as plainly as we can.
Key takeaways

- Speed-to-power, not resource selection in the abstract, is the variable that decides where and when a large data center can be built.
- LBNL put U.S. data center use at about 176 TWh in 2023, roughly 4.4% of U.S. electricity, with a projected 325 to 580 TWh by 2028 [[1]](#src-1).
- The interconnection process is the first gate. LBNL reports a median above four years from request to commercial operation for generation projects completed 2018 to 2024, which describes completed projects rather than the current queue [[6]](#src-6).
- Firmness is not the same as capacity factor. EIA reports 2025 factors of 91.0% for nuclear, 58.4% for gas combined cycle, 34.2% for wind, and 24.4% for solar photovoltaic, and the gas figure reflects dispatch rather than availability [[11]](#src-11) [[12]](#src-12).
- Advanced nuclear is a 2030s option gated by licensing progress and fuel supply rather than by physics, and this article makes no claim that it is faster than any other route.

## Data center electricity demand is growing faster than new firm supply is being connected
The demand side is the least ambiguous part of this discussion. Lawrence Berkeley National Laboratory reported that United States data centers used about 176 TWh in 2023, roughly 4.4% of total U.S. electricity consumption, and projected a range of 325 to 580 TWh by 2028, or roughly 6.7% to 12.0% of national consumption [[1]](#src-1). The Department of Energy released that report and framed it as an evaluation of the increase in electricity demand coming from data centers [[2]](#src-2).
The federal forecasting picture points the same direction. EIA has stated that it expects the strongest four-year growth in U.S. electricity demand since 2000, and attributes that growth substantially to data centers [[3]](#src-3). The Annual Energy Outlook 2026 carries the same demand growth into EIA's long-term projections [[4]](#src-4).
The near-term supply response is worth noticing because it is not what most site plans assume. EIA has written that fossil generation could rise if data center power demand grows faster than expected [[5]](#src-5). In other words, the first answer to a demand surge is usually existing dispatchable units running more hours, not new plants of any kind arriving on the schedule the load wants.
One honest observation about that LBNL range: 325 to 580 TWh is close to a factor of two. Anyone building a campus around a single point estimate inside that band is planning against a number the source itself declined to give. The useful way to read it is as a statement that demand growth is large and its magnitude is genuinely uncertain, which argues for supply arrangements that can be staged rather than committed all at once.

## Interconnection timing, not generation capacity, is the first thing that gates a new large load
The bottleneck most buyers hit first is procedural. Lawrence Berkeley National Laboratory's Queued Up analysis reports a median duration of more than four years from interconnection request to commercial operation [[6]](#src-6). That figure has to be stated precisely to be useful: it describes projects that were completed between 2018 and 2024. It is not a statement about how long projects currently sitting in the queue will take, and it says nothing about requests that were withdrawn without ever reaching operation. Read it as evidence that the process has been slow for the projects that finished, not as a forecast for the project you are contemplating.
Reform is underway and is itself a multi-year process. FERC issued Order No. 2023 to improve generator interconnection procedures and agreements [[7]](#src-7), and the practical effect on any given region depends on how each transmission provider implements it through compliance filings and how the resulting study cycles run. A rule that improves a queue does not clear a queue.
Underneath the queue sits physical transmission. The Department of Energy's National Transmission Needs Study documents where the system needs additional transfer capability [[8]](#src-8). Transmission is the slowest element in the chain and the one least responsive to a single buyer's urgency.
There is a distinction worth drawing that often gets blurred in coverage of this topic. The queue statistics above describe generator interconnection. A data center is a load, and large load interconnection runs through its own studies and its own utility or regional processes. The two are related, because a new load frequently depends on new generation and new transmission being connected as well, but they are not the same process. When a developer quotes you a queue number, ask which queue.

## Firm means available around the clock, and capacity factor is the closest public measure of it
Firm power is electricity that is available when it is called for, around the clock, without depending on weather or time of day. A data center running training and inference workloads has a load shape that is close to flat and close to continuous, which is why firmness rather than annual energy volume is the property that governs procurement.
The most accessible public evidence on how different resources actually perform is EIA's capacity factor reporting. For 2025, EIA reports nuclear at 91.0%, wind at 34.2%, and solar photovoltaic at 24.4% [[11]](#src-11), and natural gas combined cycle at 58.4% [[12]](#src-12).
Those four numbers are frequently misused, so here is the qualification that belongs with them. Capacity factor is actual output divided by output at continuous full power. It blends two very different things: whether a unit was available, and whether it was called to run. The nuclear and renewable figures are dominated by availability and resource. The combined cycle figure is dominated by dispatch, meaning market conditions and system need determined how many hours those units ran. Nothing in the 58.4% figure implies that a gas unit could not have run more. Treating it as a firmness ceiling would be a misreading, and this article does not do that.
For a buyer, the operational definition of firm is narrower than the statistic: the capacity is available, the fuel or energy source is secured, and the dispatch right belongs to you or to a counterparty obligated to serve you. Several routes in the comparison below can satisfy that definition. They differ on what stands between the decision and the energized load, which is the only axis this article ranks them on.

## Resource adequacy is tightening at the same time the load is arriving
The system this load is joining is already under study for adequacy. NERC's 2025 Long-Term Reliability Assessment identifies 13 of 23 assessment areas as facing resource adequacy challenges over the ten-year assessment period, and reports that new data centers account for most of the projected increase in demand [[9]](#src-9).
The Department of Energy's July 2025 report on grid reliability and security supplies the capacity arithmetic behind that concern. DOE states that 104 GW of firm capacity is scheduled to retire by 2030, that 209 GW of new generation is planned over that period, and that only 22 GW of the planned additions is firm baseload [[10]](#src-10). Those are DOE's figures and DOE's definitions of firm and baseload, and they are cited here as that agency's characterization rather than as an independent finding.
The near-term consequence follows from the same arithmetic. EIA has noted that fossil generation could rise if data center demand grows faster than expected [[5]](#src-5), which is what happens when new firm additions do not keep pace with retirements and new load in the same window.
What this means for a specific project is less dramatic than the headline numbers suggest, but it is more binding. An interconnection request for several hundred megawatts of new load does not arrive in a neutral system. It arrives in a planning process that is already tracking a firm capacity gap, and that context shapes how long the studies take, what upgrades get assigned, and what conditions come attached. The adequacy picture is not background color for this topic. It is part of the schedule.

## Co-location is a partial workaround, and its limits are being worked out in public
Because the queue is the bottleneck, the obvious move is to sit next to generation that is already connected. Co-location places the load beside an existing plant and reduces or avoids the need for new transmission service to reach it. It is a real strategy, it is being pursued seriously, and it is the reason several announced projects have timelines that would be implausible through a standard interconnection path.
It also introduces questions the industry has not finished answering. NERC published a white paper on the characteristics and risks of emerging large loads that treats these loads as behaving differently from conventional load, with characteristics that need to be understood and modeled rather than assumed [[13]](#src-13). That is a reliability question independent of who supplies the electricity, and it applies to a co-located load as much as to a grid-connected one.
The commercial and regulatory terms are equally unsettled. FERC has an open proceeding on co-location at PJM under Docket Nos. EL25-49-000 and related dockets [[14]](#src-14). The questions in front of the Commission include how a large load sitting behind or beside an existing generator should be treated for purposes of transmission service and cost allocation to other customers. This article takes no position on the outcome and does not assume one.
The honest summary is that co-location can shorten one path while opening another. It converts a queue and transmission problem into a regulatory and reliability question that is currently being adjudicated. For a buyer, that means a co-location strategy carries schedule risk of a different kind rather than no schedule risk, and the risk is harder to estimate because the governing rules are still being written.

## Advanced nuclear is a 2030s answer gated by licensing and fuel, not by physics
A [microreactor](https://rankshieldenergy.com/resources/what-is-a-nuclear-microreactor) is small enough to be factory-built and sited near the load it serves, and it is designed to deliver firm baseload output continuously. The reason it is not a near-term answer has nothing to do with whether the physics works. It has to do with two gates that both take years.
The first gate is licensing. The NRC's risk-informed, technology-inclusive framework for advanced reactors, 10 CFR Part 53, was published in the Federal Register on March 30, 2026 and took effect in April 2026 [[15]](#src-15). A framework existing is not the same as a license being issued under it. A developer still moves through [pre-application engagement](https://rankshieldenergy.com/resources/nrc-pre-application-process-explained), then an application, then review. The NRC has separately proposed Part 57 for microreactors, which is a proposed rule and not final, and which we cover in [a separate article](https://rankshieldenergy.com/resources/nrc-part-57-autonomous-operation-explained).
The second gate is fuel. Most designs in this class need HALEU, and a commercial domestic supply chain for it is still being established. We set out where that fuel comes from, and the primary sources for it, in [our guide to HALEU supply](https://rankshieldenergy.com/resources/where-haleu-comes-from-advanced-reactor-fuel). For scheduling purposes the point is simply that fuel availability is a first-order input to any deployment date, not a detail to resolve later.
On timing, the most defensible public characterization comes from the program itself. The Idaho National Laboratory and DOE microreactor program plan describes the program as focused on designs that could be deployed as early as the late 2020s [[16]](#src-16). That is INL and DOE's characterization of a research and development program, not a delivery commitment from any vendor, and it should not be read as a schedule any specific buyer can procure against. This article makes no claim that advanced nuclear is faster than any other route on this list. For a load that needs energizing in the next two or three years, it is not the route to plan around.

## Firm-power routes, compared by what they deliver and what gates the timing
The table below compares six routes on two questions only: whether the route delivers firm 24/7 output, and what actually governs when it can be energized. There is no cost column, and no cost comparison is implied anywhere in it. Where a cell can be supported by one of the sources cited in this article, the citation is in the cell. Where it cannot, the cell is qualitative and says so, because filling a comparison table with confident numbers that have no primary source is how these comparisons usually go wrong.

Firm-power routes for a large data center load, compared by whether they deliver firm 24/7 output and by the primary constraint on timing. This table contains no comparison of cost.

Route
Delivers firm 24/7
Primary constraint on timing

New grid interconnection for a large load
Yes, once the connection is energized
Interconnection and transmission timing. LBNL reports a median of more than four years from interconnection request to commercial operation for generation projects that were completed between 2018 and 2024 [[6]](#src-6), and the FERC Order No. 2023 reforms are still being implemented through compliance filings [[7]](#src-7).

New on-site or adjacent gas generation
Yes, when fueled and dispatched
Permitting, air authorization, fuel delivery arrangements, and equipment lead times. Stated qualitatively because no figure in the cited set covers equipment delivery. EIA reports the natural gas combined cycle fleet at a 58.4% capacity factor in 2025, which reflects how often units were dispatched rather than a limit on their availability [[12]](#src-12).

Co-location beside an existing generator
Yes, subject to the terms of the arrangement
Unsettled regulatory questions. The terms are before FERC in the PJM co-location proceeding [[14]](#src-14), and NERC has documented reliability characteristics of emerging large loads that bear on how such arrangements are studied [[13]](#src-13).

Wind or solar paired with storage
Not firm on its own. Firmness depends on how storage is sized and operated
Resource availability plus the same interconnection process. EIA reports 2025 capacity factors of 34.2% for wind and 24.4% for solar photovoltaic [[11]](#src-11).

Existing nuclear capacity, through contracts or uprates
Yes. EIA reports the U.S. nuclear fleet at a 91.0% capacity factor in 2025 [[11]](#src-11)
Bounded by the units that already exist and by what is contractually available. Stated qualitatively.

Advanced nuclear, microreactor class
Firm baseload as designed. Not demonstrated in commercial service
Licensing stage and fuel supply. The Part 53 framework was published in the Federal Register on March 30, 2026 and took effect in April 2026 [[15]](#src-15). INL and DOE characterize the program as focused on designs that could be deployed as early as the late 2020s [[16]](#src-16), which is a program characterization rather than a delivery commitment.

*Reading notes. The four-year median in row one applies to generation projects completed between 2018 and 2024 [[6]](#src-6) and is not a prediction for any project now in a queue. Capacity factor figures describe fleet-wide 2025 performance and blend availability with dispatch, so they are not a ranking of reliability [[11]](#src-11) [[12]](#src-12). Rows two and five are deliberately qualitative because the cited sources do not carry equipment lead time or contract availability figures. Nothing in this table compares what any route costs, and nothing in it should be read as a claim that one route is faster than another in the general case, because the binding constraint is site-specific.*
The pattern that emerges is not that one route wins. It is that every route is gated by something procedural or physical rather than by the availability of the technology itself. Interconnection is gated by studies and upgrades. Gas is gated by permitting and equipment. Co-location is gated by an open regulatory question. Advanced nuclear is gated by licensing progress and fuel. A buyer who knows which gate applies to their site is in a much better position than one comparing headline lead times across regions that share almost no relevant conditions.

## What a buyer should actually do, and where RankShield Energy stands
The first action is unglamorous and often deferred: enter the applicable interconnection or large load study process, and find out which study cycle you are in and what upgrades are provisionally assigned to you. Everything else on the schedule is downstream of that answer. The second is to define firm in the contractual sense rather than the marketing sense, meaning availability, secured fuel or energy source, and a dispatch right that belongs to you. The third is to stage supply rather than commit it all at once, which is the reasonable response to a demand projection whose authors published a range spanning nearly a factor of two [[1]](#src-1) and to an adequacy picture federal assessments describe as tightening [[9]](#src-9) [[10]](#src-10).
For the portion of demand that lands in the 2030s, the evaluation questions shift from queue mechanics to developer diligence. Ask about licensing path and fuel path in the same conversation, because a project can be on schedule on one and stalled on the other. We set those questions out in our [microreactor vendor evaluation guide](https://rankshieldenergy.com/resources/how-to-evaluate-a-microreactor-vendor), and the harder version of the problem, how anyone confirms what many units are doing across many sites, is in our piece on [fleet-scale verification](https://rankshieldenergy.com/resources/fleet-scale-verification-one-operator-many-reactors).
Our own status, stated plainly so it cannot be misread. RankShield Energy is a pre-applicant engaged in early regulatory interaction with the NRC. We hold no license, no permit, and no design approval. Nothing about our design has been demonstrated to or accepted by the NRC. We have never operated a reactor and we operate no fleet. We are not offering firm power to any buyer on any date, and this article is not an offer of supply.
The reason we write about speed-to-power at all is that its honest framing is also the framing that disciplines us. If the question is what can actually be energized and when, the answer for advanced nuclear is governed by licensing progress and fuel availability, both visible, both slow, and neither improved by a vendor claiming otherwise. Our working domain is the verification and attestation layer around reactor operations rather than the reactor itself. The tradeoff we accept in saying all of this is a timeline that sounds less exciting than one from a competitor willing to quote a date, and a buyer planning a multi-hundred-megawatt campus is better served by the version that holds up.

## Frequently asked questions

### How long does it take to get firm power to a new data center site?
It depends on the route and the site, and the most defensible public anchor is narrower than it is often quoted as being. Lawrence Berkeley National Laboratory reports a median of more than four years from interconnection request to commercial operation for generation projects completed between 2018 and 2024 [[6]](#src-6). That describes completed projects, not projects currently waiting and not requests that were withdrawn, so it is evidence about how the process has behaved rather than a forecast for a new request. FERC Order No. 2023 is intended to improve those procedures, and its effect in any region depends on how each transmission provider implements it [[7]](#src-7). Underlying transfer capability is documented in DOE's National Transmission Needs Study [[8]](#src-8). The practical answer for a specific site comes from entering the study process and learning which cycle you are in.

### What does firm power mean, and does capacity factor measure it?
Firm power is electricity available on demand around the clock, independent of weather or time of day, which matches the near-continuous load shape of an AI data center. Capacity factor is the closest public proxy but it is not the same thing. EIA reports 2025 capacity factors of 91.0% for nuclear, 34.2% for wind, and 24.4% for solar photovoltaic [[11]](#src-11), and 58.4% for natural gas combined cycle [[12]](#src-12). The nuclear and renewable figures are driven mostly by availability and resource. The combined cycle figure is driven mostly by dispatch, meaning how often the market called those units to run, so it is not a statement about whether they could have run more. Firmness in a contract sense means available capacity, secured fuel or energy source, and a dispatch right.

### Is there enough capacity on the system to serve this load?
Federal assessments describe the margin as tightening rather than comfortable. NERC's 2025 Long-Term Reliability Assessment identifies 13 of 23 assessment areas as facing resource adequacy challenges over the ten-year period and reports that new data centers account for most of the projected demand increase [[9]](#src-9). The Department of Energy reports that 104 GW of firm capacity is scheduled to retire by 2030, that 209 GW of new generation is planned, and that only 22 GW of those additions is firm baseload [[10]](#src-10). Those are DOE's figures and definitions. EIA has separately noted that fossil generation could rise if data center demand grows faster than expected [[5]](#src-5), which is the near-term consequence of that same arithmetic.

### Does co-locating next to an existing power plant solve the timing problem?
It addresses part of it and opens a different question. Placing a large load beside generation that is already connected can reduce or avoid new transmission service, which is why several announced projects use this approach. But NERC has published a white paper documenting the characteristics and risks of emerging large loads, treating them as behaving differently from conventional load in ways that need to be modeled rather than assumed [[13]](#src-13). And the commercial and regulatory terms are being decided now, with FERC running an open proceeding on co-location at PJM under Docket Nos. EL25-49-000 and related dockets [[14]](#src-14). Co-location therefore substitutes one category of schedule risk for another rather than removing it, and the substitute is harder to estimate while the rules are still being set.

### When is advanced nuclear realistically available, and what is RankShield Energy's status?
Advanced nuclear is a 2030s option for most buyers, and the gates are licensing and fuel rather than physics. The NRC's Part 53 framework was published in the Federal Register on March 30, 2026 and took effect in April 2026 [[15]](#src-15), though a framework existing is not a license being issued under it. INL and DOE characterize the microreactor program as focused on designs that could be deployed as early as the late 2020s [[16]](#src-16), which is a program characterization rather than a vendor delivery commitment. HALEU supply is the second gate. As for us: RankShield Energy is a pre-applicant with the NRC. We hold no license, permit, or design approval, nothing about our design has been demonstrated to or accepted by the NRC, and we have never operated a reactor and operate no fleet. We are not offering firm power on any date.
