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.
