Most places have a very different mix of electricity sources, things like hydro and imports from places further to the east (where the sun is still shinning) or wind from west-ward. Nuclear provides the same base power all around the day, etc.

The need for peaker plants to offset the need for batteries is greatly exaggerated. The batteries are mostly required for grid frequency stabilization due to renewal intermittence (clouds passing through, wind slowing down), not so much for overnight storage in most locations.

Of course this varies drastically from place to place, Hawaii for example can't really import energy production from other places.

In America it is a little different. Unfortunately California is still using 48% natural gas at this point. But they are moving in the right direction. Most states are continuing this trend. Driving in Texas you see wide load trucks hauling wind turbine parts almost every day.
