Tesla has started building its next-generation Megapack 3 grid battery, with the first units rolling off the line at the company’s new Megafactory in Brookshire, Texas.

The plant went from groundbreaking to production in 16 months and is designed to build 50 GWh of Megapack 3 a year. That’s the version Tesla says packs roughly 28% more energy into the same footprint as the Megapack it replaces.

Tesla has signed a long-term deal to buy 90% of the output of Project Sterling, a big solar and battery plant going up in Arizona.

The project pairs 509 MW of solar with a 360 MW battery, and it’s being built by ContourGlobal, the power producer owned by private equity firm KKR. It’s expected online in 2028.

Tesla has signed a long-term power purchase agreement to buy the entire output of a 140-MWac solar farm being built in northeast Texas.

The plant, called Lumen Farm, is being developed by Zelestra, an EQT-backed renewable developer. Construction is expected to start in 2027, with the farm going online in 2029.

A Tesla solar customer went to pull up their lease agreement in their Tesla account this month and found something other than a contract waiting for them: the Book of Enoch, an ancient apocalyptic text about fallen angels.

Not a scanned copy of their agreement. Not an error page. The full text of a roughly 2,000-year-old religious book, sitting exactly where their legally binding solar lease was supposed to be. Electrek confirmed it.

Tesla has launched Tesla Home, a home energy management platform powered by an AI engine called Opticaster that it says makes “hundreds of decisions” a day about when to store and use electricity to lower your bill.

However, it’s not an entirely new product as Electrek has been reporting on Tesla’s Opticaster for 5 years.
