That's been a problem with businesses in the USA for quite a while. My dad always blamed the Harvard Business School. I have no proof either way.
Well - to be fair, there's a little bit of nuance here.
Individual public utilities DO plan for the future. They all file 10-year Integrated Resource Plans (IRPs) that lay out their estimates for electricity demand in their area and how they plan to supply it (fuel mix) as well as their maintenance plans, expansion plans, etc.
What they are talking about here are high voltage long-range transmission lines that interconnect between individual utilities within a given grid (e.g. PJM or SPP) or how the grids interconnect.
There is less long-term planning on those because it's a lot more complicated, in terms who is footing the bill for it since it may have asymmetrical benefits to individual utilities.
So this new initiative is a good thing because the ability to quickly import and export power from utility to utility or grid to grid is going to be more and more important as more renewables are added and also behind-the-meter solar, which will change grid loads substantially over the next 10-15 years.
