The Milam Data Center is an AI data center campus under construction near Burlington in Milam County, Texas. SB Energy is developing it and says it will be the long-term owner and operator, with OpenAI as the customer. Lease disclosures cover about 753 MW of critical IT capacity in two buildings, with a last ready-for-service year of 2028. High-voltage interconnection is planned in phases for an initial campus load of about 660 MW, and SB Energy says it plans new generation to support the site.
