Ventasso Energy Storage, LLC is a battery storage power plant in California with a nameplate capacity of 50.0 MW.
The 50.0 MW is nameplate capacity: the most this plant's generators are rated to produce, not what it actually generates. EPA eGRID reports no positive net generation for it this year.
How it works
Why the numbers look like this: every charge-and-discharge cycle loses some energy as heat, so a storage site usually reports slightly negative net generation: it takes in a little more than it gives back. Its job is timing, not making energy.

Battery storage facilities don't generate electricity — they store it. They charge from the grid (often from solar during the day) and discharge during peak demand or to firm up renewables. EIA classifies them as power plants because they connect to the grid like one.
