Sell Land for Data Center Development in Ellis County, Texas
Ellis County is on the southern Dallas–Fort Worth transmission work Oncor has filed for large loads. If you own land in Midlothian, Waxahachie, Ennis, or the unincorporated county, that filing is the public context. It is not a price and it is not your interconnection. The read on your parcel is free, and there is no obligation unless a deal closes.
The transmission filing
On April 29, 2025 Oncor presented its Southern DFW Load Interconnection and General Grid Strengthening Project to ERCOT’s Regional Planning Group. The slide deck says the project is driven by 4,064 MW of large loads in southern DFW that had either executed an interconnection agreement or shown defined progress toward a 2026–2028 load date. Counties named include Tarrant, Dallas, Ellis, Navarro, Parker, Freestone, Leon, Henderson, Rockwall, and Collin. The cost estimate on the deck is $1.219 billion.
The same deck shows new 138 kV lines from a new Ironwood switch to Midlothian Tap. Ellis County is in the project. The 4,064 MW is not an Ellis County total. It is the multi-county load that justified the project, and only for customers who had an agreement or equivalent forward motion — a much tighter set than ERCOT’s statewide request stack.
A local zoning decision, and the statewide queue
The City of Midlothian adopted Ordinance 2025-26, zoning about 173.94 acres in the Radford Berry Survey to Planned Development District 182 for light industrial uses and a data center. That is a zoning entitlement on a defined tract. It is not a tenant announcement and not a megawatt award.
Statewide, ERCOT’s CEO told a Texas Senate committee that as of March 26, 2026 the grid operator was tracking about 410 GW of large-load interconnection requests, of which about 87 percent were data centers. A June 2026 ERCOT explainer put the mid-2026 request stack above 438,000 MW, nearly 90 percent data centers, against an all-time peak of 85,508 MW on August 10, 2023. Requested load is not deliverable load. The queue study explains why a landowner should not quote either number as the value of a pasture. ERCOT defines a large load as a site above 75 MW.

What this does not tell you
- The 4,064 MW figure is multi-county, and only for loads with agreements or equivalent progress.
- No tenant roster for Ellis County. A trade-press list of operators near a planned substation is intentionally not repeated here.
- No per-acre price.
If you own the land
- Oncor is the transmission provider on the RPG filing. Confirm the provider and the nearest substation on your parcel instead of assuming the Ironwood–Midlothian work serves you.
- City limits versus unincorporated county changes the zoning path. The Midlothian ordinance covers one tract.
- Johnson County, immediately south, is a separate page because it does not have this same filing. Submit Ellis County land with sale or lease marked.

Questions landowners ask
Does ERCOT’s 410 GW mean Ellis County is out of power?
It means requests far exceed historical peak. It does not, by itself, say whether a specific Midlothian parcel can be served.
Is the Midlothian PD a project I can tour?
The ordinance allows a data center on that tract. It does not identify an operator in the text used here.
How do I submit?
Submit the parcel. Distance to a substation is a required field because that is the screening fact.
