Twenty Month Payback for Tesla 100-MW Utility Scale Battery Storage System

Elon (and Panasonic) may have just found another multi-billion dollar business.
Going forward the chemistry probably won't be Lithium ion, maybe molten-salt or iron based, but the fact TSLA can now pitch this kind of payback probably heralds the beginnings of lithium rush 3.0, or at least the promotion thereof.

Australia has determined that Tesla 100MW battery system saved $40 million and the system had cost only $66 million. This is a 20-month payback on the investment.
Tesla’s 100MW/129MWh Powerpack project in South Australia provide the same grid services as peaker plants, but cheaper, quicker, and with zero-emissions, through its battery system

Here are the key findings from the report are that the Hornsdale Power Reserve:
* Has contributed to the removal of the requirement for a 35 MW local Frequency Control Ancillary Service (FCAS), saving nearly $40 million per year in typical annual costs
* Has reduced the South Australian regulation FCAS price by 75% while also providing these services for other regions
* Provides a premium contingency service with response time of less than 100 milliseconds...
