Obviously there are a variety of sizes and configurations, but if you assumed 3.5MWh per 20ft container, that's 5771 containers, and if you assumed a PCS container per two battery container, that's 8656 containers, just for an idea of the scale.

and then it's roughly just a rectangle of 100 by 100 containers, still big, but maybe not sooo big :-)
or a cube of 20x20x20 containers, seems small enough. (funny how we interpret numbers and sizes
I've always wondered why they don't stack them in deployment -- the containers are obviously fine with it! -- but I guess land is cheap enough not to bother.
Horizontally they need plenty of room for airflow, as each container has some HVAC-or-whatever module on the side. But vertically...
I always thought they were spread apart so much to further reduce the chance of catastrophic spread of fire from one container to another.
That would be a lot harder if you stack them since heat likes to rise.
But no clue if that is the actual reason.
Yeah, that's probably part of it. Some do have explosion vents in the top of the container.
It'd just be impressive to see a giant wall of battery. A bunch of little batteries camping in a field doesn't play the same visually. Ah well.
Foundations, maintenance, fire risk.
Land is cheap relative to a container full of cells.
They are pretty heavy and batteries already need to do adequate foundation work before installation.
I would assume it has something to do with fire hazard ?
