It's the 1st option.

There isn't enough money in it because they're useless for conventional power generation. They're also useless for places that already have a conventional power grid and just a little bit of supplementary solar/wind. There's no need to store any power, just close the throttle a little on the boiler when demand is low.

If you had a region solely dependent on solar or wind power, then storage would be a requirement for 24/7 availability. But if people can do without power at night they won't bother spending money on batteries.
