A mystery hyperscaler is seeking a 200-acre site with at least 400MW of power for a new data center in the US.

Commercial property firm JLL is working on behalf of the unnamed company to secure a site, and has put out a request for information (RFI), seeking landowners that meet its client’s requirements.

Writing on LinkedIn, JLL’s executive managing director for data center solutions, Andy Cvengros, said: “We are currently engaged in a search on behalf of an investment-grade, hyperscaler client, who prefers to remain undisclosed, for potential sites across the US.”

Investment-grade typically refers to companies with a high credit rating, usually above BBB, with agencies such as Moody’s or S&P Global.

All three of the major hyperscale providers that dominate the cloud computing market - Amazon, Microsoft, and Google - are considered investment-grade, as are companies such as Oracle and Meta, both of which are investing billions of dollars in new digital infrastructure projects in the US and beyond.

To meet the requirements of the RFI, sites must be at least 200 acres and sit within an attainment zone - an area that meets clean air standards. It must have 400MW of power available by mid-2027, JLL said, with the potential to upgrade this to 1GW, either via natural gas or from the main grid.

The land must be pre-zoned for data center use, offer a relatively flat surface, and have an adequate water supply available.

Interested parties are invited to respond to the RFI by tomorrow, October 29.
