Eland BESS 1 [Tesla building energy storage farm in Mohave CA?]

[Mrbrock]

Tesla appears to be building an energy storage farm in Mojave, CA to support the 200MW Eland 1 Solar Farm. Permit valuation is $16,800,000. Not sure how many Megapacks this will be but maybe so who has more knowledge in that arena can chime in.

Battery storage at US$20/MWh? Breaking down low-cost solar-plus-storage PPAs in the USA

In this article, experts at consultancy Apricum examine with some simple “reverse engineering” how recent low solar-plus-storage PPAs in the USA were achieved, yet another example of the competitiveness of energy storage and new market opportunities emerging via storage-plus-renewables projects.

Doing a bit more digging it looks like 2 phases for the 400MW of solar and 300MW/1200MWh of storage. Also, the $20/MWh is power purchase price, not the cost of the Megapacks (or other battery storage). A similar sized system at Moss Landing used 449 Megapacks so figure half for phase 1 or 225. I doubt 225 Megapacks cost only $1.68 million. That’s only $7500 each. Maybe they used the powerwall cost in their calculation or forgot a few 0s?

They worked out a number of $98/MWh for storage; the $20/MWh was solar plus storage pricing.

Again, still pricing of the electricity being SOLD from such systems. Not the price of the system itself. By your math, a power wall should cost $1.32 (13.5kwh/1000*$98).
