Obviously there is going to be an increased amount of solar and wind coming online in the near future, and I don't think that anyone running a power system network at the distribution or transmission level is going to dispute that. However there definitely is uncertainty about how much, and there is even more uncertainty about what our loads are going to look like with large amounts of EVs coming online and potential battery deployments. These things could have a big impact on the size and timing of grid peaks and inertia which can require big investments to manage appropriately. And as with any big investment, you want to make it at the right time, and you want to be sure that you are going to make a return on that investment.
