It’s true everything is bigger in Texas from trucks to people to batteries. A relatively small town in Texas is using a battery the size of a house for energy storage and transmission. It’s hoped that batteries like the Texas one can be used to store energy from more sustainable sources during high production periods for use later (capture solar during the day and store it for night).
BOB, short for â€œBig-Old Battery,â€ began charging up this week. The giant sodium sulfur powerhouse, which is literally the size of a house, can store four megawatts of power for up to eight hours. Before BOB came online, a single, 60-year-old transmission line was the only thing connecting Presidio to the grid. The town frequently experienced power outages. BOB serves as a much-needed back-up plan, and it holds enough power to generate electricity for the whole town.
