I'm in a major city, and the grid isn't very stable, but stable enough for me to get an electric vehicle that I need to charge once a week. Solar panels are easy to get, but the utilities are realizing that nett metering isn't a good deal for them - my otherwise high electricity bill will be zero if I get solar panels, and so they have no incentive to service my house.
That aside, because our cities are so crowded and generally hot already, everyone is very keenly aware of the heat and smoke diesel and petrol vehicles put out - if electric vehicles are affordable and charging infrastructure is in place, there's going to be no problems with adoption. The issue, of course, is that making them affordable and setting up charging infra go against the interests of the oil and gas companies that built India up to where it is so far.
To its credit, though, the government seems keen to get things going, even at the expense of breaking earlier promises to big oil and big auto. Now it's just figuring out the chicken and egg situation of bringing down costs and setting up infra without clear current demand.
