$4 Billion Data Center Phase Launches East of Valley International Airport

Key Takeaways

• The first phase represents a $4 billion investment within a planned 1100-acre data center development near Harlingen.
• Power availability, transmission capacity and network connectivity will shape how quickly the campus can expand.
• The project could broaden the Rio Grande Valley’s technology economy, although long-term employment and resource demands remain open questions.

The 1100-acre plan east of Valley International Airport places the Harlingen area squarely within the rapid expansion of artificial intelligence and cloud infrastructure. Its $4 billion first phase is substantial on its own (source). More importantly, the size of the site leaves room for a multi-building campus rather than a single computing facility.

That distinction matters. Large campuses are commonly developed in stages as power, fiber and customer commitments become available. The initial investment could cover land preparation, electrical infrastructure, cooling systems, network connections, security and one or more operating buildings. Key details, including computing capacity, construction schedules and prospective tenants, remain open.

The broader spending environment helps explain the scale. Dell’Oro Group reported that worldwide data center capital expenditure increased about 57% in 2025 as AI deployments accelerated. Meanwhile, an Analysis Atlas compilation estimated that the five largest hyperscalers, including Amazon Web Services, Microsoft Azure and Google Cloud, spent roughly $443 billion on capital expenditure in 2025 (source). Their projected 2026 spending ranges from about $602 billion to $690 billion.

Harlingen is entering the market during an unusually aggressive infrastructure cycle. Developers are looking beyond established clusters for large tracts of land, diverse fiber routes and electrical systems capable of supporting dense computing equipment. Proximity to Valley International Airport can also support equipment movement, contractor access and business travel, though an airport location alone does not make a data center site viable.

Electricity is likely to be the defining issue.

U.S. data centers consumed approximately 182 to 183 TWh of electricity in 2024, representing roughly 4% to 5% of national power demand, according to figures reviewed by the Pew Research Center. Projections indicate that the sector could account for 9% to 17% of U.S. demand by 2030. A campus spanning 1100 acres could therefore require extensive coordination involving generation, substations, transmission lines and backup systems as individual facilities come online.

Can the regional grid add capacity quickly enough without shifting excessive costs or reliability risks to surrounding customers? That will be one of the practical questions facing utilities, regulators and local stakeholders. Water use may receive similar attention, depending on the cooling technologies selected. Air-cooled and closed-loop designs can reduce water requirements, but their economics vary with climate, equipment density and energy prices.

Connectivity presents another test. Enterprise and hyperscale facilities generally seek multiple physically separated fiber paths so that one damaged route does not interrupt operations. The campus will also need internal telecom systems designed for maintainability and resilience. Those requirements can create opportunities for carriers and network contractors while improving regional fiber infrastructure more broadly.

The local economic effect will be more nuanced than the headline investment figure. Construction can generate demand for civil engineering, electrical work, concrete, mechanical systems and specialized trades. Operating facilities typically create technical roles in network operations, facilities management, security and equipment maintenance. Data centers, however, tend to employ fewer permanent workers than factories occupying comparable acreage.

Still, the project could give the Rio Grande Valley a new position in the digital infrastructure map. It may encourage additional investment in power systems, telecommunications and technical training. It could also help attract businesses that value nearby computing capacity or robust fiber access.

Execution now becomes the story. The $4 billion first phase signals ambition, but land development, utility agreements, permitting, network diversity and customer demand will determine the pace. If these requirements align, the site east of Valley International Airport could develop into a significant regional computing hub during one of the largest data center investment cycles on record.
