SB Energy

What SB Energy does

SB Energy is a fully integrated U.S. data center and power infrastructure platform that develops, constructs, owns, and operates utility-scale energy assets and AI data center campuses. Founded in 2019 as a wholly-owned SoftBank Group subsidiary and headquartered in Redwood City, California, the company operates two tightly linked business lines: (1) energy projects — utility-scale solar PV, battery energy storage (Fluence), and natural gas peaking generation — with ~5 GW operating and under construction and a 20+ GW development pipeline, and (2) AI data center campuses — including the 1.2 GW Milam County "Freebird" campus in Texas and the proposed 10 GW PORTS Technology Campus in Piketon, Ohio. The company reaches commercial operation on the 900 MWdc Orion Solar Belt in October 2024, signed a 942 MW PPA with Google in 2022, and entered a $1B strategic partnership with OpenAI and SoftBank in January 2026 as the build-and-operate partner for the Stargate initiative.

The core technology is a co-located, multi-source energy and data center delivery model that combines utility-scale solar, battery storage, and gas generation with first-party data center design (via the OpenAI partnership) and in-house construction management (via the Studio 151 acquisition, covering 20 data center campuses). The platform is designed to bypass grid interconnection queues by co-locating generation with data center load, securing priority interconnection at constrained sites, and qualifying projects for IRA domestic content and energy community adders. The company has raised $18B+ in project capital since 2019, including the first U.S. utility-scale financings to reach financial close with the IRA domestic content adder, and leads a 21-company U.S.–Japan consortium for the 9.2 GW Portsmouth gas and 10 GW Piketon data center project.

The business model is anchored on long-dated, multi-gigawatt bilateral contracts with hyperscalers (Google PPAs, OpenAI build/lease/operate) and utilities/CCAs (San Diego Community Power, Austin Energy, LCRA), plus public-private partnerships (U.S. DOE, AEP Ohio). Revenue mechanics include subscription/recurring 15-year PPAs, managed-services build/lease/operate fees on data center campuses (e.g., 20-year OpenAI lease), and capacity/ancillary services from storage assets. Pricing is quote-based and not publicly disclosed. The company filed a confidential S-1 in May 2026 for a proposed U.S. IPO as early as September 2026 at a target valuation exceeding $50B.

Revenue model

1. Long-term Power Purchase Agreements (PPAs): Multi-year (e.g., 15-year) fixed-price PPAs with hyperscalers (Google) and community choice aggregators (San Diego Community Power) for energy and renewable attributes; ~942 MW of the Orion portfolio under a 15-year PPA with Google as anchor offtake.
2. Data Center Development, Construction, and Operations: Build, own, and operate hyperscale AI data center campuses (1.2 GW Milam County TX, 10 GW PORTS Piketon OH, Borden County TX, Lubbock TX), with long-dated lease structures (e.g., 20-year OpenAI lease) and large upfront capex financed via equity, tax equity, and project debt.
3. Energy Storage and Capacity Services: Develop, own, and operate utility-scale battery energy storage (1.6 GWh Athos in Riverside County with Fluence; 954 MWh Pelican's Jaw in Kern County) providing capacity, ancillary services, and storage-as-a-transmission to California grid (CAISO).
4. OpenAI Enterprise Customer Relationship: SB Energy will become a major customer of OpenAI, leveraging its APIs and deploying ChatGPT for its employees — reciprocal revenue flow under the strategic partnership.
5. International Data Center Build-Out (France JV): JV with SoftBank and Schneider Electric to invest up to €75 billion in French AI data center infrastructure (3.1 GW phase 1, up to 5 GW total) across Dunkirk, Bosquel, and Bouchain — revenue via build fees, ownership, and power supply.

Core offering

SB Energy is a fully integrated U.S. data center and power platform that develops, constructs, owns, and operates utility-scale solar PV, battery energy storage, natural gas generation, and multi-gigawatt AI data center campuses. The company sells firm, 24/7 carbon-aware power under long-term Power Purchase Agreements (PPAs) with hyperscalers and utilities, and provides build/lease/operate services for hyperscale AI data center campuses, including a 1.2 GW Stargate site for OpenAI and a 10 GW proposed campus in Ohio.

Product overview

SB Energy operates a unified, fully integrated U.S. data center and power infrastructure platform that develops, constructs, owns, and operates critical physical infrastructure for the AI economy. The platform combines two tightly linked business lines — (1) energy projects (solar, battery storage, and natural-gas generation) and (2) data center campuses — that are designed to work together so SB Energy can deliver "speed to power" for hyperscalers. Energy products include the operating Orion Solar Belt (900 MWdc) powering Google data centers, the Athos Storage (1.6 GWh) and Pelican's Jaw (954 MWh storage + 570 MWdc solar) projects under construction, and a 20+ GW project pipeline. Data center products include the PORTS Technology Campus (10 GW, Piketon, OH), the Milam Data Center (1+ GW, Milam County, TX — built for OpenAI under the Stargate initiative), the Borden County Data Center Campus, and additional multi-gigawatt campuses in development. The platform is reinforced by the in-house Studio 151 data center construction management capability (acquired in 2026), $18 billion+ in project capital raised since 2019, and a $1 billion strategic partnership with OpenAI and SoftBank (plus $800 million of prior Ares redeemable preferred equity) supporting execution.
