Blackstone purchase highlights Sunnyvale’s role in supporting AI and advanced manufacturing
Blackstone has purchased a 134,000-square-foot manufacturing building in Sunnyvale for $95 million, a transaction that underscores growing investor appetite for properties with robust electrical infrastructure as companies ramp up research, development and advanced manufacturing tied to artificial intelligence and other compute-heavy operations.
The property, located at 350 Cobalt Way, was built in 1978 and received an upgrade in 2022. The seller was SFF Realty Partners, according to reports. Nvidia, which is a tenant in the facility, is expected to remain in place under the new ownership.
Industry reporting notes the site carries nearly 10 megawatts of electrical capacity — a feature that has become increasingly valuable across Silicon Valley as companies seek locations that can power dense computing loads without waiting for major utility upgrades.

Why power capacity matters in Sunnyvale and the Valley
Local commercial real estate brokers and developers have said for months that a key constraint for growth in Silicon Valley is electrical capacity. Properties that already have substantial power — sometimes described as "power-rich" — are increasingly sought after by tenants that operate large computing clusters, development labs and advanced manufacturing facilities.
- Existing capacity reduces development time: Buildings with high electrical capacity can avoid long lead times for utility upgrades, making them more attractive to tenants who need immediate or near-term deployment.
- Higher rents and investment premiums: Power-rich properties often command higher prices or rents because they can accommodate compute-intensive users, including AI developers and semiconductor-related firms.
- Strategic value for investors: Institutional investors like Blackstone have been adding such assets to their portfolios to capture demand from technology companies scaling up operations.
Blackstone has publicly said investments in data centers, power and other digital infrastructure have been a notable part of its infrastructure strategy. Company officials have indicated such assets contributed significantly to the firm's infrastructure business, a point that helps explain the firm's activity in the Bay Area market.
Regional context and nearby activity
The deal in Sunnyvale comes as other major technology companies pursue similar facilities elsewhere in Silicon Valley. For example, OpenAI is reported to be closing in on a lease for a 70,000-square-foot building at 2950 Zanker Road in North San Jose that has about 19 megawatts of electrical capacity. Those moves together illustrate a broader shift: rather than relying solely on new utility builds, firms are seeking existing structures that can support heavy power loads.
For Sunnyvale, the sale may have several local implications. It could mean greater stability for tenants already in the building, like Nvidia, and signal to other investors and tenants that Sunnyvale properties with upgraded infrastructure command strong market interest. It also raises questions about future land use, local employment, and how cities in the Valley manage the balance between industrial, office and data- and power-intensive operations.
As institutional investors continue to target infrastructure serving AI and advanced manufacturing, Sunnyvale — centrally located in the heart of Silicon Valley — may see more transactions focusing on buildings with the electrical capacity to host next-generation computing hardware. City planners and utility partners will likely remain key stakeholders as development patterns shift to accommodate those demands.
