Corporate nuclear power purchase agreements Market Outlook 2026–2036: Growth Drivers, Key Companies, Strategic Developments & Adoption Forecast — A Meticulous Next™ Foresight Brief

This Meticulous Next™ brief examines corporate nuclear offtake, where a technology company or other large buyer contracts the output of an existing, restarted or new nuclear plant, or funds an uprate or a new reactor in exchange for future power. It tests how far these agreements become a standard route to firm clean power for large buyers by 2036, and what that means for nuclear operators, reactor developers, technology buyers and utilities.

Contracts have grown from single plants to portfolios. Constellation agreed in September 2024 to restart Crane for Microsoft under a 20-year agreement for 835 MW, and in June 2025 signed a 20-year agreement with Meta for 1,121 MW from Clinton plus a 30 MW uprate. In September 2025 Vistra agreed a 20-year, 1,200 MW agreement with Amazon at Comanche Peak. In January 2026 Meta announced agreements with Vistra, TerraPower and Oklo that support up to 6.6 GW of new and existing nuclear capacity by 2035. The conclusion is that the largest technology buyers have moved from one-off deals to multi-gigawatt programmes in about 16 months.

Buyers are now paying for new capacity at existing plants. On 30 September 2026 Amazon and Constellation announced a 20-year, 690 MW agreement at Calvert Cliffs that includes a 190 MW uprate expected between 2030 and 2032 and more than USD 3 billion of investment. In its November 2026 results Constellation reported a 20-year agreement with Google to fund more than USD 4.3 billion of uprates across 11 nuclear units in Illinois, Pennsylvania and New Jersey, adding about 890 MW with the first uprate expected in 2028, and a separate 15-year load following agreement for 2,700 MW in PJM. The conclusion is that buyers are funding extra output from the existing fleet, which is the quickest source of new nuclear power.

New reactors are funded years ahead. Meta funds the development of up to eight TerraPower Natrium units, with delivery of the first two units of up to 690 MW each as early as 2032, and prepays Oklo for a 1.2 GW power campus in Ohio with a first phase as early as 2030 and the full 1.2 GW by 2034. The conclusion is that a technology buyer is carrying development risk in return for supply from reactors still to be built, and the first deliveries from advanced reactors will fall within the horizon of this brief.

The brief treats corporate nuclear offtake as a high-impact signal with a ten year horizon to 2036. It identifies which nuclear operators, reactor developers and technology buyers move first and what each means for agreements, uprates and clean firm supply. It is a focused 112-page decision brief that presents an indicative trajectory rather than a segmented market model.

Existing plants are the first source. Under its agreements with Meta, Vistra will supply 2,176 MW from the Perry and Davis-Besse plants in Ohio under 20-year agreements, with energy from uprates at Perry, Davis-Besse and Beaver Valley bringing the total to 2,609 MW by 2034. The conclusion is that existing plants provide large, firm output at known cost, and buyers use long agreements to secure it before competitors do.

Uprates and restarts add output. The Crane restart for Microsoft, the Duane Arnold restart for Google and NextEra and the Calvert Cliffs uprate for Amazon all add capacity at sites that already hold licences. The conclusion is that restarts and uprates can be delivered in a few years, while new reactors take longer, so they set the pace in the first half of the horizon.

Advanced reactors depend on funded development. TerraPower Natrium units combine a sodium fast reactor with storage, and Meta reports up to 2.8 GW of baseload capacity plus 1.2 GW of built-in storage across the programme. The conclusion is that buyers are paying for firm supply that can follow load, which is the product that wind and solar cannot provide.

Utilities are building tariffs. Google and Georgia Power agreed to about 96 MW of uprates at Vogtle and Hatch under a tariff awaiting Georgia Public Service Commission approval, and Constellation reported a first transaction of its Peak+ product for 270 MW of unit-contingent power from 2028. The conclusion is that utilities and operators are creating standard products so that smaller buyers can take part.

The limits are contract length and credit risk, cost and schedule of new reactors and licensing, fuel and supply chain limits. The brief tests each limit against the cost trajectory to 2036.

The corporate nuclear power purchase agreements market, covering power purchase agreements, uprate and restart funding, development prepayments and utility tariffs under which corporate buyers contract nuclear power from existing, restarted and new reactors, measured by annual revenue from energy delivered and development funding paid under such agreements, and excluding utility sales to general grid customers, government funded programmes and fuel supply contracts, is valued at USD 2.5–4 billion in 2026 and is projected to reach USD 18.26–29.22 billion by 2036, at a CAGR of 22%.

The 2026 base rests on energy delivered under agreements from existing and restarted plants and on development funding paid for uprates and new reactors, mostly in the United States, with growing activity in Europe and Asia. Growth then follows the number of restarts and uprates completed, the first advanced reactor deliveries and the share of data center load contracted to nuclear.

The forecast is sensitive to the cost and schedule of new reactors, state regulator approvals and licensing.

The base case assumes uprates and restarts complete on schedule and the first advanced reactors begin delivery by the early 2030s, bringing the inflection to about 2032 and a 2036 value near the middle of the range. An accelerated case assumes strong federal support and fast licensing, bringing the inflection to 2030 and lifting the 2036 value to the top of the range. A delayed case assumes cost overruns and licensing delays at new reactors, moving the inflection to 2034 and holding growth at the bottom of the range.

Growth drivers

• Corporate clean power commitments.
• Data center electricity demand.
• Grid reliability and firm supply needs.
• Government support for nuclear.

Enablers

• Uprate, restart and advanced reactor advances.
• Federal loans and regulatory support.
• Contract and project evidence.
• Operator and technology buyer partnerships.

Restraints and barriers

• Contract length and credit risk.
• Cost and schedule of new reactors.
• Licensing, fuel and supply chain limits.
• Differences in national rules and standards.

The direction of corporate nuclear offtake is set by corporate demand for firm clean power, technology buyer and nuclear operator investment, data center load growth and grid constraints, advances in uprates, restarts and advanced reactors, and the readiness of buyers and operators to sign long agreements.

The key participants in corporate nuclear power purchase agreements and nuclear offtake include Constellation Energy Corporation, Vistra Corp., Talen Energy Corporation, NextEra Energy, Inc., Dominion Energy, Inc., The Southern Company, Électricité de France SA, Fortum Oyj, GE Vernova Inc., Oklo Inc., NuScale Power Corporation, Cameco Corporation, BWX Technologies, Inc., Doosan Enerbility Co., Ltd., Korea Hydro & Nuclear Power Co., Ltd., Rolls-Royce Holdings plc, Microsoft Corporation, Alphabet Inc., Amazon.com, Inc., Meta Platforms, Inc., Duke Energy Corporation, Tennessee Valley Authority, Centrus Energy Corp., Oracle Corporation, Switch, Inc., Equinix, Inc., Digital Realty Trust, Inc., Energy Northwest, Mitsubishi Heavy Industries, Ltd., Orano SA, Siemens Energy AG, Fluor Corporation, Jacobs Solutions Inc., Ontario Power Generation Inc., the International Atomic Energy Agency, the World Nuclear Association, the Nuclear Energy Institute, the United States Nuclear Regulatory Commission, the United States Department of Energy, PJM Interconnection, L.L.C. and the Georgia Public Service Commission.

The brief profiles representative participants in each archetype and assesses which are positioned to lead as uprates complete and advanced reactors begin delivery.

Constellation, Vistra, Talen and NextEra lead among nuclear operators and generators, GE Vernova, Oklo, NuScale and Rolls-Royce lead among reactor developers and equipment makers, and Microsoft, Alphabet, Amazon and Meta lead among technology buyers. Competitive intensity is rising as buyers compete for a limited supply of existing plant output and uprates.

Where value migrates.

In 2026 value sits with operators of existing plants that sign long agreements with technology buyers and with the owners of restart and uprate projects. By 2032 it moves toward reactor developers and fuel suppliers as the first advanced reactors deliver under funded agreements, because the buyer has paid for development in advance. By 2036 it settles with nuclear agreements as a standard route for corporate firm clean power, where existing plant capacity, uprates and financing carry the margin. Margins hold for operators with licensed capacity and long contracts, and narrow for developers that depend on a single buyer.

Meta agreements for up to 6.6 GW, Amazon and Google agreements with Constellation in late 2026 and federal loan support for uprates support growth, while contract length and credit risk, the cost and schedule of new reactors and licensing and supply chain limits hold back the pace.

Cost overruns at new reactors, licensing delays and state approvals could slow progress. The brief therefore tracks four indicators: contracted nuclear capacity, uprate and restart capacity completed, advanced reactor delivery dates and price of nuclear power under contract.

Existing plant agreements by technology buyers first, then uprates, restarts and advanced reactor deliveries at scale, then standard route status is the expected order of change.
