Just curious. I assume installing solar system in MA is worth it, or you wouldn't be doing it. How long do you expect it to take to payout? What part of your home's energy usage will your system supply?
TOD pricing will have an effect on some usage, some people might run their dishwashers at night to save a few nickels and dimes, and many EV owners would continue to charge overnight as they currently do.
I am in "sunny" FL and about 10 years ago I had a survey done to see if solar was a viable option. for me the math didn't work. I could only expect to cover 2/3 of my needs with solar and it was an almost 20+ year break even point. For me the best application of solar would be for heating my swimming pool. have someone come in and survey your home to see how much "juice" you could actually capture with the panels and then do the math.
I was in San diego in 1986 for the republican nation convention and there were daily power disruptions across the state back then. CA has done little to improve their generation and distribution issues.
They are very few and far between now, at least where I live in So Cal (Torrance/Redondo Beach area). I honestly don’t remember the last time we had a rolling black out. Last couple of summers there have been short “brown outs” (which has disrupted my manufacturing company
) but very few disruptions at the house. Probably depends on where in CA one lives and which power company. 
staring thing is the roll-black outs happen when most EV's are not on grid - but late afternoon as AC usage ramps up and solar drops off…
You are looking at from the "glass half empty" perspective. Treat TOD not as "electricity more expensive during some time window" but rather "electricity is discounted during another time window". The goal is not to switch all usage, but only the usage which can be switched, for for example with current discounted electricity at night, you will not turn your AC off during the day, or your computers, etc, but you probably will schedule your EV to charge at night if you don't need it charging during the day. That will nicely flatten your load curve, which helps the utilities.
I live in the Seattle area, no rolling blackouts since I've lived here (~20 years). I lived around Boston for a bit too, no rolling blackouts. I lived in Dallas area too, never experienced a rolling blackout but I will qualify this with the fact that I didn't live there long (but did during what was described at the time as the hottest summer in many years, think 106F at night on some days). Living in East Bay near San Francisco, regular rolling blackouts, mostly in the summer IIRC. All of those places I just mentioned have actual population and economy IMO, or do they not qualify as actual population and economy by California standards?
can you cite such a place? I am frequently in the northeast US and I reside in FL, both of those regions have very large populations and vibrant economies.
this is just a guess but I suspect that the majority of people who charge their cars do so at home over the night time period.

it's a nationwide problem - the grid needs upgrading.
it should cover everything and be paid off in 6-7 years. With the EV and a pool with a heat pump our electric bill is high. We have good sun coverage and no trees blocking.
