Tesla to build Megapack 3 factory
- Tesla said on April 22 that a new factory outside Houston is on track to start producing Megapack 3 later in 2026, extending the company’s push deeper into utility-scale battery storage. - Tesla tied the Texas project to a broader 2026 manufacturing buildout, while local officials previously said the Brookshire-area site carries roughly $200 million of investment and about 1,500 projected jobs. - The plant adds a third major Megapack hub as Tesla leans harder on energy storage after record 46.7 gigawatt-hours of deployments in 2025.

Tesla said its new factory outside Houston is on track to begin producing Megapack 3 later in 2026. (assets-ir.tesla.com) The update came in Tesla’s first-quarter 2026 shareholder deck, which said progress had continued at the new Megafactory outside Houston and that the site will build Megapack 3 for Megablock. (assets-ir.tesla.com) Tesla also said in that deck that it had started ramping new factories across batteries and battery materials and was preparing lines for Megapack 3, Cybercab and the Tesla Semi. (assets-ir.tesla.com) Megapack is Tesla’s utility-scale battery system, built to store electricity from the grid or from wind and solar projects and discharge it later when demand rises. Tesla’s Lathrop, California, Megafactory is designed to produce 10,000 Megapacks a year, equal to 40 gigawatt-hours of storage. (tesla.com) The Texas site has been taking shape for months in Brookshire, in Waller County west of Houston. County officials approved tax abatements in March 2025, and local reporting later said the project was expected to bring at least 1,500 jobs by 2028. (energy-storage.news) (houstonpublicmedia.org) Those local agreements described a project with roughly $200 million in facility and equipment investment. Houston Public Media reported the site had begun hiring in November 2025, after county officials said Tesla would need at least $75 million in taxable inventory by January 1 and $300 million by the end of year three. (houstonpublicmedia.org) (energy-storage.news) Tesla is expanding that footprint as its energy business grows faster than its car business. The company said it deployed a record 46.7 gigawatt-hours of energy storage in 2025, including 14.2 gigawatt-hours in the fourth quarter alone. (ir.tesla.com) The Houston-area plant would give Tesla another Megapack production base alongside Lathrop and its Shanghai Megafactory, which Tesla opened to serve demand outside North America. Tesla has not publicly listed annual output for the Texas site in its April 2026 shareholder deck. (assets-ir.tesla.com) (tesla.com) For now, the clearest new fact is timing: Tesla says Megapack 3 production in Texas is still scheduled to start later in 2026. (assets-ir.tesla.com)
