    isn't going to change the problem of electric utilities having to meet their own generation needs with minimal system import and purchased power.

    In addition, environmentalists should stop claiming we are going to solve our electricity generation problems by using new electric grid approaches.   Note that increasing the distance that you have to wheel power over the grid from the generation source to the electric customer inherently increases transmission line loss which is an inescapable part of the problem of electric transmission over long distances.

    •  True. (4+ / 0-)

      But if we want efficient, reliable, and environmentally non-destructive energy, you know what?  We have to take it on as an integrated federal project, not farm it out to private companies to run on the tightest margin (least service, least maintenance, least reliability) they can get away with for the biggest profit.  The power grid is a natural monopoly (it's too expensive for duplication by multiple parties and too essential to be allowed to have gaps or failures) and a public necessity.  That's the classic description of something too important to leave to the private, deregulated market.

      HVDC for long distance gives the grid a distance "robustictacy" that AC cant, while AC trans loss is 7% DC is 3%.

      IIRC resistive heating losses are worse with AC, specially in summer.

      Ultra HVDC is good for 1000-2000-2500 miles, Green Bay to LA, if you will. HVDC has its place, but by itself is not a solution.
