Tesla building secret giant batteries connected to Texas power grid, report says

That's a lot of power.

Tesla is making batteries a lot bigger than the ones for cars. 

Tesla appears to be taking another step into the energy business. The electric car company is reportedly building a giant battery that would plug into the Texas power grid, which had a massive failure in February due to a freeze across the state. 

Tesla has a secret project to build more than 100 megawatts of energy storage in Angleton, Texas, according to a report from Bloomberg on Monday. Gambit Energy Storage, a Tesla subsidiary, is reportedly doing the building. It also shares the same address as Tesla's auto plant in Fremont, California. Images from the site show equipment that's covered up, but workers can be seen wearing Tesla logos.

In February, a cold front brought rare snowfall to Texas and led to power outages across the state. It's unclear whether the project would be used to prevent any future issues stemming from a similar power failure.

Tesla CEO Elon Musk began developing a Tesla gigafactory in Texas over the summer. The state is also one of the locations for operations by SpaceX, another of Musk's companies.

Telsa didn't immediately respond to a request for comment.
