WI: More TVAs?

In 1937, there were plans for seven more TVA type authorities to be set up around the country, which, although considered 'must' bills at Roosevelt's second inauguration that were certain to pass, never came to fruition. So, how do we get the plans through, and what are the short and long term effects? Are more set up? Does this lead to more acceptance of government as a direct part of the average American's lives, or a backlash?
 
in Inside USA (published in 1946), John Gunther mentioned an Ohio Valley and a Missouri Valley authority by name. Don't know which the others might have been (Mississippi? Delaware?) but one suspects the answer would be to have been short-term acceptance and longer-term backlash toward privatization.

Makes one wonder what the effects of cheaper hydroelectric power would have been through World War II and beyond. Maybe it would have slowed (not denied) conversion of transit from streetcars/trolley coaches to buses. Could be air conditioning could have become more prevalent sooner--or the same could be said for TV. Possibly it could have paved the way for a wider, faster deployment of nuke plants also.
 
Well, this also mentions Savannah Valley and the Columbia Valley (possibly others, but only the first page is open to public view.)

Might more of these authorities also lead to a greater consideration for more centralised planning and co-ordination? Perhaps this leads to far more logically organised urban expansion and more thoughout public transit and the like?

Also, is it possible these authorities could act as springboards for other federal regional development authorities? Instead of more GSEs being chartered under LBJ and onwards could we see more regional economic development mandates tacked on?
