Data centers in California are boosting the state's AI infrastructure through several upcoming data centers, such as the Goodman Group Silicon Valley Data Center, Prime Data Centers Sacramento Data Center, and Amazon East Gilroy Data Center. 

California has about 296 colocation data centers with 9 cloud service providers and 296 network fabrics. The California data center market ranks third in the U.S., with major data centers built across Northern California (mainly in Silicon Valley) and Southern California (particularly in Los Angeles and Santa Clara).

In this blog, we have listed the major upcoming data centers in California, ranked by capacity as of 2025.

List of Top Upcoming Data Centers in California 2025

Ameresco AI Data Center at Naval Air Station

Recently, in September 2025, Ameresco partnered with CyrusOne (acquired by Kohlberg Kravis Roberts (KKR) and Global Infrastructure Partners (GIP) in 2022) to build a 100 MW data center at Naval Air Station (NAS) Lemoore, California. The AI-optimized data center will be collocated with a dedicated on-site energy generation facility built by Ameresco. This generation facility will form a microgrid system that includes engine generators, control systems, and infrastructure upgrades. 

The Lemoore data center facility is planned to meet the federal security and compliance standards, including FedRAMP, FISMA High, and DoD Impact Levels 5 and 6, and will align with NIST cybersecurity frameworks. The facility will feature air-gapped architectures, cross-domain solutions, and zero-trust security models to secure sensitive workloads within the data center. 

The project is being built on land leased by Ameresco from the Department of Defense.

The first segment of the project is expected to be operational by 2027. Currently, the development agreements are still being finalized.

Recently, the company announced an update about the LAX1, stating it is on track with development approval expected in Q2 FY2026.

Amazon Data Services East Gilroy Data Center

Amazon Data Services is building a data center in East Gilroy in the northeast area of California. The project will span 438,000 sq ft of information and energy storage facilities at the southeast end of Arroyo Circle on a 56-acre site. 

The project will be built in two phases; phase 1 will include a single-story data center building spanning 218,000 sq ft and will require a 49 MW connection to PG&E (Pacific Gas and Electric Company, part of PG&E Corporation). Phase 1 will also be supported by 25 emergency generators, each with a 2.5 MW capacity to power the data center servers. Plans also include the addition of a 600 kW generator to power other functions, such as lighting, in case of a power outage at the facility. 

Phase 2 of the project will include another single-story building, which will also span 218,000 square feet. Plans include adding an off-site power transmission upgrade and BESS of up to 50 MW, along with a 2,500 square foot security building.

STACK Infrastructure SVY02A Campus

* SVY02A Campus Design

The SVY02A Campus is a 48 MW data center campus being constructed by STACK Infrastructure at Santa Clara, California. The Santa Clara data center will span 9 acres and will include 4-story data halls, each spanning 551,216 sq. ft. 

The data center will have 8 data halls, each with 6 MW capacity, spanning 24,000 sq ft with single & multi-tenant shell options. An on-site substation is planned with committed power through Silicon Valley Power (SVP) for the initial 12 MW. The project will be supported by a dual utility feed with N+1 block redundancy through generators and UPS. 

The project design supports multiple cooling deployments, including liquid to chip. Closed-loop water cooling systems provide optimal cooling for high-density workloads and N+1 345-ton air-cooled chillers with quick restart. The construction of the project is completed and is awaiting power from the local grid, Silicon Valley Power (SVP), as of November 2025.

Digital Realty 32 MW Data Center

Digital Realty is building a 32 MW data center in Los Angeles. The data center campus will include a 13-story facility near One Wilshire, with approximately 485,892 sq ft of floor space. The company recently acquired the land for the campus.

Conclusion

Data centers in California continue to expand the state's digital infrastructure with new colocation and large-scale facilities.  Several government bodies, such as the California Energy Commission, California lawmakers, and the California Department, are supporting building new data center projects across Silicon Valley, Los Angeles, and Sacramento. 

Thus, upcoming data centers such as Goodman Group Silicon Valley Data Center, Prime Data Centers Sacramento facility, and Amazon’s East Gilroy development, and several other projects, continue to strengthen its position as one of the leading data center markets in the United States.
