Cipher McLennan Data Center, Riesel, Texas
Overview
Cipher McLennan is a central Texas development record, not a verified operating data center. TYPE3’s map data names Cipher Digital Inc., gives E State Highway 6 in Riesel, and records Announced with 0 MW. Cipher materials describe an approximately 293-acre opportunity with up to 500 MW of total potential or gross capacity. The figure is subject to load studies and the ERCOT approval or related process, so it is not approved, energized, delivered, or current customer IT load.
The timing has also changed. The 2024 business update targeted energization in Q4 2027, while a 2026 business update places McLennan in a 2028 planning group and references the ERCOT batch process. Both dates belong in the record. Local reporting describes a proposed project near the Sandy Creek Power Plant and says building plans depended on the end user, which supports a development narrative but not a construction claim.
The public-facing name “Cipher McLennan” should remain linked to any legal or site alias discovered during later verification. The address and map pin are location leads, not parcel proof. Searchers looking for a 500 MW Texas data center need the distinction between target capacity, interconnection conditions, and energized load stated plainly. No demand-response contract or delivered workload is established here.
Questions
Is Cipher McLennan a 500 MW operating data center?
No. The 500 MW figure is a company-stated potential gross capacity subject to studies and approvals. TYPE3’s map data records 0 MW and Announced status.
Where is the McLennan site?
TYPE3’s map data places it near Riesel on E State Highway 6 in McLennan County. The parcel and exact public-facing location still need confirmation.
When will Cipher McLennan be energized?
The 2024 materials targeted Q4 2027, while 2026 updates place the site in a 2028 planning group. Treat both as dated estimates, not a commitment.

This state sits outside ERCOT and outside the survey. Sponsoring one funds the work of charting it — pulling its interconnection queue, large loads, and price data onto the map.
