I'm having trouble believing that its that cheap- battery prices have not fallen 8x in the last two years. I believe the report I was reading was from 2021.

- bryanlarsen 3y agoThe report is from 2021. The sources they used for prices are from earlier. 160 -> 40 is 4x. That's about 3 years worth of price drops at the rate they fell in the 2010s.
- Straw 3y agoAccording to this recent source, its currently 100-130 $/MWh: https://www.lazard.com/media/2ozoovyg/lazards-lcoeplus-april-2023.pdf https://www.lazard.com/media/2ozoovyg/lazards-lcoeplus-april... And that's for 100MW solar with 50MW of 4-hour storage
- bryanlarsen 3y agoSure, but only 1/6 (or less) of the energy uses the battery. $10 + $130/6 = $31.67. Sell for $40/MWh and profit.
- Straw 3y agoSure, you can sell solar for cheaper when the sun shines. But if we want to consider replacing the entire grid, we need to look at the cost including storage and not accounting for slack in other generation sources!
