This is the kind of thing that is funding the massive expansion in renewable energy build-out at the moment. The whole reason there's an energy transition happening is that solar and wind and batteries are cheap enough you can make a lot of money building them, and that'll remain true until basically the whole grid is renewable (finally kicking out the expensive gas turbines), and the average price drops to reach cost of supply.

(And the kind of optimisation that happens with this kind of paper is really in the margins stuff. It generally helps the predictive power of the grid, and usually doesn't make much money once more than one group starts doing it, since it's pretty cheap to run and the margins shrink quickly)
