If generally true, the utilities would be pestering their PUCs for an increase in the fixed monthly fees ALL their customers pay.
Net metering is a subsidy to PV owners, plain and simple. Let's not pretend it is anything else. That subsidy is paid by those who do not have PV and net metering.
OTOH, the two-meter approach which charges retail rates for consumption and pays wholesale for production is a rip-off for PV owners. The reason is that those owners have to pay a markup for ALL electricity, including that portion which they self-consume.

Most (not all) natural-gas power plants are so-called "peaker" plants which are built to come online to handle variable loads. But peaker plants cost more to operate than base-load plants due to the reduced thermal and financial efficiencies which can be achieved.
SageBrush wrote:The utilities have massive over capacity at night, while EV charging during the day would strain the current system without decentralized PV input. So it makes perfect sense for the utility and the system to prefer PV+EV as a pair. Either in isolation is more of a problem for them.
More nonsense. In 2016, CA produced approximately 6% of their electricity using solar power
. That 6% has already completely eliminated the mid-day peak on sunny spring days and turned it into a valley significantly lower than the nighttime load
And this is with far less than 1% of CA's total transportation energy coming from electricity. The simple fact is that converting ANY vehicle to electricity which is drawn during the nighttime will increase fossil-fuel usage unless there are wind generators in place and the wind just happens to be blowing at that time. This is true REGARDLESS of how much solar generation is in place. And with any non-trivial penetration level of BEVs we will experience electricity peaks that occur at nighttime. Again, this is regardless of how much PV is put in place.
Similarly, PV penetration levels beyond about 10% of total electricity production will cause serious operational difficulties for the power companies.
Where I live, electricity is the primary source of heat. As a result, in the wintertime, electricity consumption peaks AT NIGHT. If you add loads at night, you simply increase the peak load.
The obvious conclusion is just as I have already stated:

IMO, there is no way around this fact. Trying to do both without moving EV charging to the daytime will require us to build twice as many batteries as would be required with daytime charging. That would make no sense at all because it would cause excessive damage to the environment while simultaneously slowing the growth of BEVs.
