Construction of the massive new Tesla energy storage system at the PG&E substation in Moss Landing is almost complete, and a new flyover video shows the rows of gleaming white battery units. 

At 182.5 megawatts, the battery system would be one of the largest in the world when it comes online and adds capacity to the power grid, enough to power more than 130,000 homes. The project was approved by the Monterey County Planning Commission in February last year. 

Meanwhile, another, even bigger battery project locating on an adjacent lot has come online. On Jan. 6, Vistra Energy announced that its 300-megawatt system has connected to the power grid, calling it the largest battery in the world. The company is already building the second phase of the project to expand it to 400 megawatts.
