The "MW, all listings" tile above is a wider measure (every tracked site that reports MW, any status, unverified directory listings included), so it is larger than Total listed.
Broker lease rates (CBRE/JLL): available on paid plans. Asking base rent per kW of critical IT capacity. Electricity is normally billed separately (metered pass-through), plus cross-connects and one-time fees. Signed deals, term and size change the number.

The market has drawn regulatory attention: city officials have adopted stricter approval processes for new data center development, and Texas Research Park has emerged as a focal point for regional deployment.
This pairing means operators pursuing incremental capacity will encounter elevated friction in securing grid access and managing interconnection timelines; it does not preclude new builds, but it narrows the margin for oversized power bids or aggressive multi-site expansion plans without prior offtake certainty.
No recent deals are currently tracked in San Antonio, leaving operator consolidation and capacity transfers opaque.
Regulatory scrutiny and the CAUTION verdict together suggest San Antonio's next phase will hinge on grid infrastructure upgrades and interconnection queue management rather than land or operator availability. Watch for announcements of transmission or substation investments tied to specific facility phases.
