Silicon Valley data centers totalling nearly 100MW could 'sit empty for years' due to lack of power — huge installations are idle because Santa Clara can't cope with surging electricity demands

Data Center.

In the heart of Silicon Valley, two freshly built data centers designed for the world’s most power-hungry computing workloads are standing empty. Digital Realty’s four-story SJC37 facility and Stack Infrastructure’s SVY02A campus in Santa Clara, California, were both constructed to host tens of megawatts of high-density IT hardware. Instead, they’re waiting for electricity.

According to a Bloomberg report, both projects are complete but idle, with no firm timeline for full energization. Digital Realty’s 430,000-square-foot site was built for 48 megawatts of critical load. Stack’s nearby SVY02A campus — also designed for 48 megawatts — includes its own substation and eight data halls. Together, they represent nearly 100 megawatts of capacity ready for servers, accelerators, and networking gear that cannot be switched on until the local grid catches up. According to the report, both "may sit empty for years."
