Elon Musk: Insufficient Land Near Storage Cabinets for Full Solar Power Quality
Elon Musk responded that energy quality can be addressed with Tesla's Megapack. There is not enough land nearby for Terafab to be fully powered by solar energy, but it will partially use solar energy.
Terafab is a chip factory planned by SpaceX and Tesla in Grimes County, Texas, about an hour's drive northwest of Houston, with an estimated cost of approximately $16.8 billion. It claims to cover over 100 million square feet and aims to produce terawatt-level computing chips for robots, autonomous vehicles, Starlink, and orbital data centers. The site is located next to the decommissioned Gibbons Creek coal-fired power plant and reservoir, using water from the reservoir rather than local groundwater.
The previously disclosed power supply plan primarily involves on-site natural gas units and large-scale battery arrays, with documents not listing Tesla's photovoltaics as a primary energy source. Chip equipment is highly sensitive to voltage stability and harmonics, with millisecond-level disturbances potentially ruining entire batches of wafers; gas turbines produce synchronous AC power directly, while photovoltaics require inversion, necessitating additional management of harmonics and intermittency. Energy storage is described as quality buffering rather than converting photovoltaics into baseload power.
xAI has purchased approximately $2.69 billion worth of Megapacks from Tesla this year. Tesla is also planning a gigawatt-level photovoltaic manufacturing and storage facility in the Houston area, but manufacturing photovoltaics and supplying power to the wafer factory are two separate grids. Musk has directed most of the computing power goals towards space, citing that the total electricity generation in the U.S. is about 0.5 terawatts, which is insufficient to support a trillion-watt computing ambition.
Partial solar energy means the factory will still rely on gas for baseload, with photovoltaics only covering daytime needs. Land constraints have removed the "fully green electric wafer factory" from engineering options, leaving a combination of gas, cabinets, and a small area of panels. Grid connection and permitting will still follow natural gas power plant protocols, not photovoltaic power station protocols.
In market mechanisms, the seller is a unified control system selling chip capacity, natural gas power generation, and storage cabinets simultaneously, while the buyer requires stable voltage for wafer equipment and seeks narratives in the capital market. The event-driven aspect is external inquiries about why they do not use their own photovoltaics. Funding initially flows towards turbines, batteries, and land, with photovoltaic manufacturing investments accounted separately. Beneficiaries include the Megapack production line and on-site power generation construction; pressures arise from portraying Terafab as a purely clean computing base and the land planning around the factory needing to accommodate both gas and batteries.

Musk combines three products in one statement: the wafer factory needs clean sine waves, the storage cabinet sells millisecond-level buffering, and photovoltaics provide kilowatt-hours during the day. The lack of nearby land acknowledges that the energy density of ground photovoltaics cannot fill a terawatt narrative for the chip city. The reliance on gas remains because baseload and energy quality can be achieved faster than covering the area with panels. While marketing photovoltaics and storage for data centers, the choice of gas for the most expensive factory indicates that the customer is the wafer equipment, not the brand manual.
The capital path reflects the division of labor within vertical integration: SpaceX handles on-site power generation and satellite computing, Tesla manages batteries and some photovoltaic manufacturing, while chips attempt to bypass the outsourcing queue. The reservoir and old coal plant site address water and high-voltage corridors but do not resolve the land issue for solar energy. Megapack transitions from being a customer for data centers to a component for energy quality at its own wafer factory, locking storage demand into the same cash flow. Space computing remains a narrative that highlights insufficient ground electricity, without changing how many megawatts of gas Grimes County needs tonight.
Analogies can be drawn to TSMC's Tainan plant using dedicated substations and uninterrupted power systems, Intel incorporating power quality into equipment contract appendices, and data centers switching to turbines while queuing for grid connection. The industry phase is that artificial intelligence pushes chip factories from "buying green power certificates" to "building dispatchable power sources." Those who can deliver within harmonic specifications can open lines; those with only daytime panels can only play a supporting role.
Structural judgment pertains to energy structure choices after technological substitutions are hindered. The mechanism is: photovoltaics solve for energy quantity, while wafer factories purchase waveforms. Insufficient land halts energy quantity solutions, forcing storage to only correct waveforms, with baseload reverting to gas turbines that can operate 24 hours. Partial solar energy acknowledges physical limitations, not a transitional phrase on the roadmap.
