List of Top 5 Largest Upcoming Digital Realty Data Center Projects in 2026

Digital Realty-Blackstone Hyperscale Campus JV

One of the largest upcoming projects in Digital Realty’s global pipeline is its USD 7 billion hyperscale joint venture with Blackstone to develop four major data center campuses across Frankfurt, Paris, and Northern Virginia. The multi-year program will deliver approximately 500MW of total IT load capacity across 10 data centers across Tier 1 markets in Europe and North America.

Under the agreement, Blackstone will acquire an 80% ownership stake in the joint venture through an initial capital contribution of roughly USD 700 million, while Digital Realty retains a 20% interest and will oversee development and day-to-day operations. The campuses are being developed in phases, with 46MW already under construction and partially pre-leased. Around 20% of the total planned capacity is expected to come online by 2025, with the majority scheduled for delivery in 2026 and beyond.

Atlanta Campus Expansion

Digital Realty is planning a major expansion in the Atlanta metro with a new two-building data center campus in Forest Park, Clayton County, approximately nine miles south of downtown Atlanta. Filed through its Digital Fort Gillem LLC affiliate, the project is undergoing a Development of Regional Impact review with the Georgia Department of Community Affairs.

The ATL 15 and ATL 16 campuses will span roughly 1.9 million square feet across a 97-acre site that was formerly part of the Fort Gillem US Army base. The development is expected to deliver approximately 200MW of capacity and represents an estimated USD 2 billion investment. The site sits within the broader Gillem Logistics Center and will be integrated with Digital Realty’s existing Atlanta footprint.

Garland Data Center Expansion

Digital Realty is expanding its planned Garland data center campus in the Dallas-Fort Worth metro. The company has filed to develop Digital Garland DFW37, a 410,000 square foot facility at 1502 Ferris Road featuring six 8MW data halls and dedicated tenant office space. Construction on the USD 120 million building is scheduled from March 2025 through October 2026.

Beyond DFW37, Digital Realty is advancing a broader multi-building expansion across its Garland footprint. On a 45-acre site at 1702 W. Campbell Road, the company plans to construct up to four additional data center buildings, each representing a minimum capital investment of USD 160 million. 

Full build-out of the campus is expected to exceed 1 million square feet, with total developer investment surpassing USD 600 million, excluding additional tenant capital. The expansion also includes a 172,000 square foot facility at 1505 Ferris Road, where Wells Fargo is confirmed as a tenant.

Vernon Data Center

Digital Realty has acquired a five-acre site at 4400-4458 Pacific Boulevard in Vernon, California, for approximately USD 48.8 million as part of its strategic expansion in Southern California. The property is expected to support up to 32 megawatts (MW) of IT capacity, positioning it as a high-density facility aimed at meeting accelerating demand for AI and cloud workloads in the Los Angeles metro.

The site currently includes a 253,200 square foot industrial building originally constructed in 1925. Located in Vernon, just southeast of downtown Los Angeles, the property benefits from strong connectivity infrastructure and access to independent local power resources.

FRA20 Data Center

In November 2025, Digital Realty began construction of FRA20, its latest state-of-the-art data center in Frankfurt. Located at Digital Park Fechenheim, the facility is designed to support AI innovation and high-density deployments in one of Europe’s most important data hub markets.

FRA20 will deliver approximately 16 MW of installed IT capacity across more than 8,100 square meters. The project will be completed in two phases, with the first phase expected to be operational in spring 2027.

The facility will leverage advanced cooling systems and energy-efficient architecture to support AI and machine learning workloads. In line with Digital Realty’s global sustainability strategy, FRA20 will be matched with 100% renewable energy.

Once fully built out, Digital Park Fechenheim is expected to comprise 11 interconnected data centers delivering up to 200MW of IT capacity across approximately 90,000 square meters, further adding to Digital Realty’s capacity in Germany.

Conclusion

Digital Realty’s future in the data center industry is closely tied to AI-driven transformation. They have a strong pre-leasing momentum, a USD 1.4 billion backlog, capital-efficient joint ventures, and continued expansion across key global metros. The company is positioning itself as a neutral, global platform for hyperscale cloud and AI workloads. As demand for high-density computing and sustainable infrastructure rises, Digital Realty’s large-scale, Ai data centers are expected to play a central role in shaping the next phase of digital infrastructure growth.
