Like someone else said, 2024 has a "total eclipse", but its path is more central, largely avoiding the solar-heavy west. It will still hit Texas (ERCOT), but since the date is early April the grid conditions should be relaxed enough that it will be another event where some planning should mitigate potential issues.

The next eclipse that would hit in the summer (which would have tighter conditions and more reliance on solar to serve demand) won't be until August 2044. Who knows exactly what the grid will look like by then, but you will certainly see a massive dip in solar generation.
