DER is great and can solve some problems, but its not the answer for everything. In a diverse world we need many technologies to support progress and the energy needs of new industries and consumers. There are many aspects of traditional grid that we take for granted that have not been fully solved in a 100% renewable grid scenario (physical inertia, black start capability, long duration storage as an example).
What you say 'exists in reality', mostly exists in a world where there is an ability for Vermont to rely on imports from neighbouring nuclear and coal to make sure the power doesnt go out.
The point of my comment is to offer an alternative point of view to the dominant narrative which is used by politicians to create policies and incentives that sound good and get votes, but don't actually solve the energy issues in a cost effective manner.
>More than 5,500 people in Vermont have similar home battery systems.
This is _literally_ a rounding error. It's less than 1% of Vermont.
So it's your comment that's truly baffling, though I'm sure others would appreciate if you posted your own source. There's certainly no power plant getting shut down because 5,500 customers have batteries, but again I'd love to be proven wrong.
I would argue that Vermont is an exotic example of where batteries offer disproportionate value. A city with a single privately owned monopoly supplying power and able to import power from nearby hydro, coal and nuclear plants.
