alt Hacker NewsThe massive battery buildout in places like California and Australia are seriously eating into these night time windows already, and we’ve really just gotten started. California will exit 26 with roughly ~20% fossil, and still dropping fast every year as batteries move deeper into the night. The opportunity for nuke to sell at higher prices during the night is being eaten fast. Batteries filled with cheap excess daytime solar are cheaper than nukes already, and can be deployed instantly. The niche won’t exist soon, which is why noones building nukes.
(Yes there is a small amount of legacy nuke in California too.)
Batteries are still too expensive to cover the whole night. So it will take few years before they will threaten nuclear base load. But they are already cheaper to serve electricity from solar or wind during 4 hours evening peak consumption than running natural gas peaker plants. Plus they reduce the scale of grid upgrades in many cases.
