SpaceX has proposed building a $24 billion natural gas power station and data centre complex near the Port of Brownsville, Texas, according to a public hearing notice from Starbase.
The site would cover more than 400 acres between Boca Chica Boulevard and the port.
In August, Brownsville commissioners voted to remove the land from the city and place it under the control of Starbase, the town that is home to SpaceX's launch site.
Starbase commissioners will consider a property tax break for the project at a public meeting on 9 December.
At the same August meeting, Brownsville approved a separate deal allowing SpaceX to pay up to $220 million towards water and sewage infrastructure.
Power for AI
The project is part of Elon Musk's push to build AI data centres with their own dedicated power supplies.
That strategy has been complicated by a shortage of gas turbines, the engines used to generate electricity in gas power plants.
SpaceX is also developing its own system for linking Nvidia chips, codenamed Kessel.
It replaces conventional cabling with a single large circuit board and is designed for data centres both on Earth and in space.
Turbine row
The competition for turbines has turned bitter.
SoftBank, the Japanese investment group, recently took a $3.7 billion hit to its earnings after giving up more than 13 gigawatts of reserved turbine capacity.
Musk had publicly claimed SoftBank defaulted on its orders.
SoftBank's chief financial officer said the claim was "simply not correct at all".
Local politics
The plan has also become caught up in Texas politics.
Gina Hinojosa, the Democratic governor-elect, campaigned against a related SpaceX land deal near Boca Chica State Park.
She has since softened her stance, saying she can work with Musk's companies "on our terms".
