LCOE of batteries is 10x the LCOE of generation from my understanding.
- ben_w 6y agoGiven the prices listed in the article, that sounds like it was true for the dates listed, but both (PV) generation and (Tesla) batteries are cheaper now than they were in 2018, and I calculate Tesla batteries cost less than 7.5x even for the best generation. • https://www.carbonbrief.org/solar-is-now-cheapest-electricity-in-history-confirms-iea https://www.carbonbrief.org/solar-is-now-cheapest-electricit... • https://www.theverge.com/2020/9/22/21450916/tesla-battery-pack-elon-musk-price-kilowatt-hour-ev-cost-tabless https://www.theverge.com/2020/9/22/21450916/tesla-battery-pa... • https://news.ycombinator.com/item?id=24816619 https://news.ycombinator.com/item?id=24816619
- epistasis 6y agoTaking the mid points of the ranges from Lazard's latest: https://www.lazard.com/perspective/lcoe2020 https://www.lazard.com/perspective/lcoe2020 Solar is about $35/MWh, and storage, including the energy to charge the battery, is about $190/MWh. So the multiple is now about 5x. This ratio is key for determining the balance between overprovisioning generation capacity versus storage. When excess generation capacity is cheaper, we will lean harder into that and use less storage, and when storage is cheap we will use more of that and have less excess power.
