San Jose residents near Silver Creek Valley Road will likely see months of construction and new electrical infrastructure if a plan filed by real estate giant Prologis moves forward. The company is proposing a three-story data center totaling 516,000 sq ft on roughly 15 acres at 5977 Silver Creek Valley Road that would deliver 99MW of capacity and include an on-site substation.
What will change for nearby residents
The application indicates construction would take about two years and that Prologis will fund necessary transmission upgrades. That could mean heavy equipment and utility work, new traffic patterns during construction and long-term changes to the site’s use from the industrial warehouse initially proposed there.
"will cover the costs of transmission upgrades."
The site has a development history: Duke Realty originally bought the parcel in 2021 for $40.2 million from Peery Arrillaga and filed plans for a 281,875 sq ft industrial warehouse that never advanced to construction. Prologis acquired Duke Realty in 2022 as part of a broader $23 billion purchase and now controls the property.
Local energy and planning implications
The plan includes an on-site substation to support the facility’s power needs. Prologis has said it will fund transmission upgrades required to deliver the capacity. City planning and utility approvals will be necessary before work can begin, and residents should expect public review opportunities through San Jose’s planning process.

Prologis is pursuing other large-scale data center projects in San Jose, including a proposed campus near Zanker Road adjacent to the Los Esteros Energy Center that could total 400MW across multiple buildings. Nationally and internationally, the company says it has roughly 5.6GW of power committed or in advanced negotiations and is targeting up to 10GW over the next decade.
For San Jose policymakers, the project raises questions about local grid capacity, traffic and land-use priorities. The developer’s commitment to pay for transmission upgrades may ease some utility concerns, but the project will still require city permits and environmental review before construction can begin.
Residents who want updates should monitor San Jose Planning Department filings and notices, as the proposal will move through public-review stages that include additional details on traffic mitigation, noise, landscaping and construction scheduling.
Reporting for this item relied on filings and reporting by national outlets and industry sources identifying the site, ownership history and the developer’s stated commitments on power upgrades.
