I think you are missing the point. The protest should be against polluting the city to power a non-necessary activity by not going to the mall.
AND if the government purposely delayed an electricity connection by months or years, then you should protest against them too. The above problem doesn't seem to be an issue of supply & demand of electricity, but more of a power tussle between the builder & authorities for possible kickbacks.
Related, it seems like India is almost power surplus according to these sources : [1] [2] [3]
Nearly every major set up runs on diesel generators, where all would you stop going?
These sort of protests, bans etc don't scale well.
