Nice to see folks "getting religion" and installing dynamic voltage support. This is a growing concern as larger and larger renewable resources are being built remote from the load centers. Adequate transmission and robust voltage support are crucial components needed to reliably deliver the energy.

What do you think has been the hold up behind getting such support installed? Simply heads in the sand?
