Generators don't ramp up/down immediately. Especially when peak power usage is 4-5pm, people getting off work, but also closer to sunset. That's a lot of power

Generators don't ramp up/down immediately. Especially when peak power usage is 4-5pm, people getting off work, but also closer to sunset. That's a lot of power that needs to be generated immediately for stability. More solar (without batteries) makes that worse. https://en.wikipedia.org/wiki/Duck_curve https://en.wikipedia.org/wiki/Duck_curve
