CalEthos, a new data center company, plans to build a 300 MW wholesale campus in Southern California. According to the company, a site of one million square meters, 92,900 square feet, will be built on an 80 hectare site in the Lithium Valley of Imperial County, surrounded by geothermal power plants.

According to CalEthos, it's been hiring people from Microsoft, Google, Meta, NTT, CenturyLink and Global Switch. The company's president and COO Joel Stone was formerly the head of global site sourcing at Meta, and spent two years as the SVP of RagingWire.


In partnership with the architecture and design firm HDR Engineering, the company carried out a feasibility study for Phase 1 of the project. To provide 100 percent clean geothermal and solar energy for the site, it has hired Z Global Energy Services to develop a grid connectivity plan.


It has also brought on American Dark Fiber to complete engineering and permit preparation of multiple diverse paths for accessing several close-by long-haul and dark-fiber communication networks.


The second phase is now under way, including the procurement of infrastructure and building designs, preparatory work for a new construction project as well as customer selection activities.
