Tesla Megapack Factory in Texas

by

There are report that there will be a third Tesla megapack factory and it will be in Texas. The will be located in Waller County, within the Empire West Industrial Park, near Houston and part of the Houston metropolitan area (close to Katy, Texas). It is expected to span approximately 1.6 million square feet, though one report mentions 1.03 million square feet, indicating a possible discrepancy or evolving plans. This makes it significantly larger than Tesla’s existing Megapack factories in Lathrop, California (440,000 square feet) and Shanghai, China (880,000 square feet). I believe the 1.6 million square feet report. Shanghai is twice the size of Lathrop and Texas will be twice the size of Shanghai. There are two small buildings at the Shanghai megapack factory. This would mean 40 GWH/year in Lathrop california, 80 GWH/year in China and 160 GWh/year in Texas. IF it is 1 million square feet then assuming constant capacity scaling we would expect 100 GWh/year of production (25000 megapacks per year).

The building and industrial park is 6 miles from Katy, Texas and 36 miles from Houston, Texas.

It appears to be the building at 111 Empire Boulevard, Brookshire Texas.

The dirt beside the building at 111 Empire Boulevard looks like it is exactly big enough for 600,000 square feet with a parking lot.

There was previous talk in 2023 and 2024 that Tesla had leased the building as a warehouse. It now appears that the reports are saying the building was adjusted to specifications.

The facility is projected to create around 1,500 jobs in the region and generate $20-30 billion/year in annual revenue once operational. It would make 40,000 megapacks per year and the megapacks would cost $500,000 to 750,000 each. Costs of megapacks have dropped from $2 million each for 3.9 mwh system to about $1.0-1.2 million now to about $500k-750k in a couple of years.

Tesla is investing approximately $194 million in upgrades and equipment for the facility, which will occupy two existing buildings. The Waller County Commissioners Court has approved a tax abatement program to support the project, incentivizing its development.

This will be Tesla’s third Megapack factory globally, following the ones in California and China. The use of existing structures is expected to allow production to start earlier than if a new building were constructed from scratch.

This information Tesla-focused news outlets like Teslarati, DriveTeslaca and CoveringKaty sources.

Tesla will operate a new Megapack battery storage manufacturing facility at a 1 million-square-foot building, which was initially constructed with no tenant on speculation that it would attract jobs and economic development.

Stream Realty built the so-called “spec” building at its Empire West business park. Stream will also oversee the construction of a new 600,000-square-foot distribution facility with some manufacturing capabilities. When completed, Tesla will occupy both buildings.

It sounds like Stream Realty construction of the 1 million square foot is well underway.

This was the view of the Shanghai megapack factory under construction.

I made a size estimate of it.
