Tesla's New Texas Megapack Factory: 50 GWh and 1,500 Jobs

BASENOR Team / June 08, 2026

Tesla is building its biggest Megapack factory yet, and it's going up just outside Houston. The facility in Brookshire, Texas is targeted to produce 50 GWh of energy storage annually once fully ramped — more than the company's California and China plants combined — and is expected to employ up to 1,500 people by 2028.

What's Being Built — and Why It's Different:

The Brookshire site, located in Waller County's Empire West Industrial Park roughly 35–40 miles west of downtown Houston, isn't just a scaled-up version of Tesla's existing Megapack lines. According to verified reports, the factory will produce two next-generation products: the Megapack 3 and the new Megablock system.

The Megapack 3 offers approximately 5 MWh per unit — a roughly 28% increase over the Megapack 2's 3.9 MWh capacity — with a redesigned thermal management system that reduces connections by 78%. The Megablock takes that further, integrating four Megapack 3 units with a transformer and switchgear into a single 20 MWh assembly. That kind of density matters enormously for utility-scale grid projects where installation time and footprint are major cost drivers.

The complex spans two buildings totaling over 1.65 million square feet: Building 9 (~1 million sq ft) handles primary manufacturing and robotic assembly, while Building 10 (~600,000 sq ft) covers warehousing and logistics.
