Regulatory capture can slow this trend. But as the article indicates, it's only temporary. Advances in energy storage and moderated consumption allows customers to disengage from the grid entirely.
If you're in the business of making electricity by burning stuff, or you sell oil, or cable TV, or internet, or 50 other good examples, you had better start reinventing your business now.
Those business make very rich people richer, so they're going to fight it tooth and nail, which is a shame when they could be putting that effort into reinvention.
I doubt that will change. If you want companies to have enormous amounts of idle capacity waiting around for a cloudy day then you have to make sure they can make money.
i.e. when the massive majority of houses and business have their own solar and storage, we don't need to pour billions into coal plants and the grid to have it sitting around waiting for... nothing.
