President Donald Trump’s administration announced a massive data center deal with Japan on Friday, March 21, 2026. Over 20 companies from the United States and Japan formed the Portsmouth Consortium to redevelop former Department of Energy facilities in Piketon, Ohio, into a natural gas and artificial intelligence hub. The core project carries a $33 billion price tag and forms the centerpiece of broader Japanese investments under the U.S.-Japan Strategic Trade and Investment Agreement.
The deal centers on the Portsmouth site, a defunct uranium enrichment complex previously operated by the Department of Energy. SoftBank, through its subsidiary SB Energy, leads the effort. The consortium will build a large natural gas-fired power plant to supply electricity directly to a hyperscale AI data center complex planned for the location. Reports indicate the data center could reach 10 gigawatts of capacity, one of the largest such facilities in the United States. American Electric Power, known as AEP, participates as the local utility partner. The group will also fund new transmission lines, electrical substations, and supporting gas pipeline infrastructure.
This announcement marks the latest concrete step in a $550 billion Japanese investment commitment to the United States. The pledge originated from trade negotiations in 2025. In exchange for tariff relief on Japanese exports, including a reduction to 15 percent on certain goods, Tokyo agreed to direct hundreds of billions into American projects over several years. The first tranche, valued at $36 billion, was unveiled in February 2026 and included:
- The Ohio natural gas plant
- An oil export terminal in Texas
- A synthetic diamond manufacturing facility in Georgia
Friday’s announcement advances the second round of projects, pushing total disclosed commitments closer to $100 billion when combined with related energy and infrastructure efforts.
Timeline of the agreement shows steady progress. President Trump and Japanese Prime Minister Sanae Takaichi met in Tokyo in October 2025 to outline the framework. Additional details emerged during their Washington summit in March 2026. Commerce Secretary Howard Lutnick and other administration officials highlighted the Portsmouth project as a direct outcome of those talks. SoftBank executives joined federal and local leaders in Pike County, Ohio, for the formal rollout. Construction planning for the gas plant and data center infrastructure begins immediately, with initial site preparation already underway at the DOE-owned land.
The project addresses surging electricity demand driven by artificial intelligence development. Data centers require enormous amounts of reliable power. Traditional grid capacity in many regions has struggled to keep pace. By locating the facility at the Portsmouth site and pairing it with dedicated natural gas generation, the consortium ensures the data center does not strain existing household electricity supplies. This approach aligns with the Ratepayer Protection Pledge that President Trump secured with major tech companies including Amazon, Google, Meta, Microsoft, OpenAI, Oracle, and xAI in early March 2026. Under that pledge, data center operators commit to building, bringing, or buying new power generation and covering all related infrastructure costs so that American consumers do not face higher bills.
SB Energy will lease the former uranium enrichment facility from the Department of Energy. The company shoulders a significant portion of redevelopment expenses, including environmental remediation and modernization of the site. AEP Ohio will handle grid integration, new substations, and transmission upgrades. Japanese firms supply key components valued in the billions as part of the larger investment package, such as:
- Power station systems and transformers
- Optical fiber cables
- Electronic modules from Mitsubishi Electric, TDK, Fujikura, and Hitachi
Economic implications for Ohio stand out clearly. The project creates thousands of construction jobs in the short term and hundreds of permanent high-tech and operations positions once the data center comes online. Pike County and surrounding areas in southern Ohio gain a major economic boost after decades of decline tied to the closure of federal nuclear-related facilities. Local leaders described the announcement as a turning point for regional revitalization. Federal officials emphasized that the deal brings advanced AI infrastructure to the heartland rather than concentrating it solely on coastal tech hubs.
Broader national security and competitiveness factors drove the agreement. The Trump administration has prioritized rapid expansion of AI capabilities to maintain technological superiority. Reliable domestic power sources reduce dependence on foreign supply chains for critical computing infrastructure. Natural gas provides immediate baseload power while longer-term options like small modular nuclear reactors receive parallel investment through the same U.S.-Japan framework. The deal counters aggressive Chinese advances in AI and energy technology by securing allied capital and expertise for American soil.
Critics of previous administrations often pointed to bureaucratic delays and regulatory obstacles that slowed energy and infrastructure projects. This deal moved forward through direct negotiations between the two governments and private sector partners.
- The use of existing DOE land avoided lengthy new permitting battles.
- Dedicated funding for transmission and pipelines eliminates common bottlenecks that have stalled other data center proposals elsewhere in the country.
Japanese participation extends beyond capital. Firms bring specialized manufacturing strengths in power electronics and cooling systems essential for large-scale AI operations. The arrangement strengthens bilateral supply chains and reduces vulnerabilities exposed during recent global disruptions. At the same time, the structure keeps majority control and operational benefits within the United States through the consortium model and federal oversight of the DOE site.
The $33 billion Ohio project represents only one piece of a much larger picture. Additional tranches under the $550 billion commitment target small modular reactors in Tennessee and Alabama, further natural gas facilities in Pennsylvania and Texas, and advanced manufacturing initiatives. Total proposed energy investments linked to the framework now exceed $100 billion. Administration officials describe the approach as pragmatic deal-making that delivers jobs, energy security, and technological progress without burdening American taxpayers.
Local utility planning already accounts for excess power from the new gas plant. Once the data center reaches full operation, surplus electricity will feed into the regional grid, providing a buffer for other users. This built-in redundancy supports the administration’s goal of affordable and abundant energy. It also demonstrates how targeted private investment can solve grid constraints that government programs alone have failed to address in recent years.
Environmental reviews for the site will proceed under existing federal guidelines for brownfield redevelopment. The project incorporates modern emissions controls on the gas turbines. Proponents note that powering AI infrastructure with domestic natural gas offers a lower-carbon alternative to coal or imported energy sources while delivering the reliability AI systems demand.
State and federal coordination played a key role in finalizing terms. Ohio Governor Mike DeWine’s office worked closely with Commerce Department representatives. The Department of Energy facilitated the land lease and provided technical data on the Portsmouth site’s prior infrastructure. These steps cut months off typical timelines for similar developments.
Industry analysts project that U.S. data center power demand could double or triple within the next five years as artificial intelligence adoption accelerates across sectors. The Portsmouth hub positions the United States to capture a larger share of that growth. By securing Japanese financing and technology, the deal accelerates deployment without forcing utilities to raise rates on residential customers.
President Trump’s Ratepayer Protection Pledge set the policy foundation. It required tech companies to internalize the full cost of their power needs rather than shifting expenses to the public. The Japan deal operationalizes that principle at scale by tying new generation directly to new demand. This model prevents the cost socialization that occurred in some earlier data center expansions.
The Portsmouth Consortium includes American and Japanese entities working under a unified structure. Governance ensures compliance with U.S. national security standards for critical infrastructure. Data center operations will adhere to strict cybersecurity protocols given the sensitive nature of AI workloads.
Construction milestones include initial groundbreaking for the gas plant later in 2026, with phased data center buildout following. Full commercial operation targets the early 2030s, though initial capacity could come online sooner. Job training programs in Pike County will prepare local workers for roles in construction, operations, and maintenance.
This agreement demonstrates a clear break from prior policies that often treated energy abundance and technological leadership as separate issues. By linking them through strategic international partnerships, the Trump administration advances both simultaneously. The result brings concrete investment, jobs, and infrastructure to American communities while reinforcing alliances that counter strategic competitors.
The deal secures a major win for U.S. energy and technology policy by delivering dedicated power for advanced AI on American soil through allied investment.
