It's also not clear if they factored in battery costs. They mention lithium battery costs have also decreased in cost but not clear if its included. Batteries are a requirement for consistently delivering solar power. You cant just flip the sun on and off.
- DamonHD 1y agoNo generator runs 100%. Not so long ago the UK nuke fleet was managing only about 60% caopacity factor. The grid system runs as a whole with generators backing one another up. The last two big load shedding incidents (since the turn of the century, ~500k people had power cut to keep the rest of the grid up) on the GB grid involved thermal generators tripping; the older one was nuke+coal, the newer one gas+wind. And in general we know when the sun is going down a long time in advance so grid operators can plan for it!

This is even more important for solar eclipses: unlike normal sunrise and sunset which are gradual, the ramp in a solar eclipse is very steep, so the grid operator has to have enough reserve prepared in advance and ready to absorb the sudden decrease (and increase) in solar generation.
