So you might be able to increase all the turbines from 50 to 70. That will absorb the excess power for a moment. Then you're maxed out and still need to shed just as much power as before.
So it doesn't help in any significant way, you have to set up a more complicated grid with very expensive transformers, and it requires you to design all your turbines to be twice as strong.
