When two men knocked on Ida Huddleston’s door last May, they carried a contract worth more than $33m in exchange for the Kentucky farm that had fed her family for centuries.

According to Huddleston, the men’s client, an unnamed “Fortune 100 company”, sought her 650 acres (260 hectares) in Mason county for an unspecified industrial development. Finding out any more would require signing a non-disclosure agreement.

More than a dozen of her neighbors received the same knock. Searching public records for answers, they discovered that a new customer had applied for a 2.2 gigawatt project from the local power plant, nearly double its annual generation capacity.

The unknown company was building a datacenter.
