It could be that the grid can't handle any significant generation of PV
energy. If it could, economics would dictate that excess PV energy would
be sold, not shut down.
The other possibility is this will produce an incentive to create
hydrogen storage for excess PV energy. In my opinion, that's an
excellent use for electrolysis plus either hydrogen turbines or fuel
cells. Note, for this application, the hydrogen does not need to be
compressed.

We have a nation wide grid and a market for power. Storage is less of a
problem than cost. CA may not be selling at a price people are buying. It's
also hard to raise level of pump storage when the water gets used for ag.
My first guess is CA has distorted the market with subsidies, etc. It is
likely a pendulum swing, the asking price will have to come down. Supply
greater than demand. Some one is going to get some electrons below cost.

they're actually deliberately cutting output - there's more supply than
demand. Springtime is a particular problem because there's ample
sunshine,
but the weather is mild, so there's little need for heating or aircon.
Long-term storage would seem to be the real answer, I guess (I"m not an
expert), and maybe the legislature needs to revisit their RE goals.
But for the immediate situation, more EVs => more demand => more efficient
use of installed PV, no?
Since charging tends to be at night, short-term storage would be a factor,
I
suppose. Seems easier to implement than long-term storage, but again,
what
do I know?
