Let's do some math:

2.1GWh

And

Multi billion dollar price (let's assume 3 billion)

2.1GWh - > 3billion

2.1MWh - > 3 millon

2.1kWh - > 3000 Usd /2.1

1KWh - > ~1430 USD

Considering that 1kWh in lithium ion batteries is like 150 USD they aren't getting a good value out of it.

I don't think the multibillion price tag is about the physical battery itself.

It's probably the cost of the entire project. Which includes:

  • Project management
  • Engineering
  • Digging the whole
  • Security
  • Maintainance
  • Environmental impact analysis (among many other analysis)
  • Reducing the environmental impact
  • Permits (and a LOT of bureaucracy)

The list goes on. Notice how I didn't even mention the battery itself.
